1st: what is the difference from your answer to Solution 1 ?
2nd: you have answered a nearly 14 year old question - that looks like Reputationpoints-hunting and you could get banned for it ...

Ralf Meier 20-May-24 14:27pm View

Thanls Maciej ... but btw : what was wrong ?

Ralf Meier 10-May-24 14:30pm View

Sorry for my late response - it could have been earlier if you used the REPLY-widget insteat of writing a new comment.
Basicly @Grame_Grant has posted a possible Solution to do that.
You should use the SELECT CASE Statement with for example an Integer-Variable.
Now each Step of yor Statemachine is a new CASE of this with a new Value of that Integer.
After doing a step you should increase that Variable for the next step. Inside this next step you wait for the result to increase the Variable again ... and so on ...
Is that clear for you or should I create an example ?

Ralf Meier 5-May-24 6:14am View

Please explain a little bit better what you are trying ... perhaps with some examples, What are the condition(s) to go to the next step ?

Ralf Meier 22-Apr-24 18:43pm View

Have you ever checked with the Debugger if :
- GetSesionData is really called ?
- data is not Null ?
- what is data.Errorcode ?
- what is data.Chargerstate ?

Suspending the Layout isn't necessary - I suppose that one of those listed things is your problem ...

Ralf Meier 9-Apr-24 3:05am View

Without seeing what your Debugger "says" I suppose that the assignment to the Eventhandler isn't realized at the right point.
I suggest that you don't do it manually and assign it with the Designer - so it will be established with the Form call.
Why have you coded it inside the TopliNapitciButton_Click-method ?

Ralf Meier 11-Feb-24 5:14am View

based on this Solution I posted some little modifications for you - see below ...

Ralf Meier 9-Feb-24 3:29am View

If you have a question to OG then use the "Have a Question or Comment"-Widget inside his Solution. In that case he is notified.
This is not an answer so it's downvoted !

To answer your question : you don't know how to add location-points ? Make a new Point and assign the Groupbox-Location to it. After that you add your Button.X-Value to the Point.X-Value and the same with the Y-Value. If you want that the Cursor is middle over the Button the add also the half of the Button-Height to the Point.Y and the same with the Width to the X-Value ...

Ralf Meier 5-Feb-24 4:12am View

I'm not quiet sure what you are exactly doing (not much code posted) - but perhaps it could help if you write an Invalidate to your Label and after this an "Application.doEvents" before you start your method ...

Ralf Meier 20-Nov-23 15:21pm View

what is thge sense of using an unvisible Listbox ?
and ... do you allways want to get the last Item of the Entries inside yor Listbox ?
In fact you could get any Item of your Listbox at any time - independant of the Listbox.Visible-State

Ralf Meier 15-Nov-23 18:13pm View

I'm sorry but I can't use it - I only have VS 2010 which doesn't support a higher Framework than 4.0.

Perhaps I will by a newer Version if it is cheaper to get ...

Ralf Meier 15-Nov-23 18:07pm View

+5 It`s much easier as my own Solution ... 👍 (and works similar 😃)

Ralf Meier 15-Nov-23 11:09am View

Also an additional a very good Sugestion from you was the PropertyName-Deklaration - some of the Properties have a Name which is not useful to be worked with the Deserializer - mean or example "input:0{sub-deklarations}" - here I could give a different Propertyname for the Deklaration and for the Deserializer ...

Ralf Meier 15-Nov-23 8:59am View

Thank you very very much, Richard. My +5
Of course, you posted in C# - but that wasn't a problem for me (I only prefer coding in VB)
The de-serialisation is working now ... 👍

With the original posted JSON from me you are right - I had formatted it for better seeing without the commas (replace "," with vbCRLF)

Ralf Meier 14-Nov-23 4:27am View

thanks a lot for that Info :-)

Ralf Meier 14-Nov-23 4:26am View

The using of this Framework is a kind of Lazyness at me ... so now I will switch to 4.6.2

Oops ... from where do I get the "System.Net.Http" ?
I'm using Framework 4.0 and it seems that there is no Namespace like that in it ...

Ralf Meier 14-Nov-23 2:32am View

Since there is no useful information to be found in the web I decided to make an Article (later when I'm finished) which describes how to work with the Shelly-Devices (Smart-Home Relais)

Ralf Meier 14-Nov-23 2:29am View

Thanks a lot for sharing your sample - I will a little later make tries with it ...
To make it easier for me : how should a request look like which gets an answer from the device ? Would you be so kind to improve your Solution with that Method ?

Ralf Meier 13-Nov-23 14:41pm View

which part isn't clear for you ?
I want to send the HTTP-Command "http://192.168.xxx.xxx/relay/0?turn=off" with the click of a Button for example.
Freezes means that I could send it 2 times and it works and then teh application isn't responsive anymore ...
Don't you have a useful sample for that ?

Ralf Meier 12-Nov-23 11:30am View

have you rad this article : https://github.com/dotnet/winforms/issues/3063

Ralf Meier 12-Nov-23 11:09am View

did you set it inside the "InitializeComponent" of your class to false ?

Ralf Meier 12-Nov-23 11:07am View

the next manipulator is your "SelectionIndent"-Setting inside the "InitializeComponent" of your class. With this you could manipulate the left position (left margin). I thought that this was planned by you ...

Ralf Meier 12-Nov-23 11:00am View

but what I'm complete not understood is what you tried to achieve ...
It would be nice if you will explain it to me ...

Ralf Meier 12-Nov-23 10:57am View

If I understood it right your problem comes from the Property "ShowSelectionMargin" you set to true - if it's false the shift from 10 pixes is away. I couldn't find out where this could be manipulated ...

Ralf Meier 12-Nov-23 9:32am View

it is still untestable for me.
To see what I mean you should move this class to a new independant project ...

Ralf Meier 12-Nov-23 9:29am View

it's only for me to be able to test it by myself ...

Ralf Meier 12-Nov-23 8:44am View

I'm sorry - there are too much declarations/definitions inside your class which came from/point to outside it - change your code to let it independant from your project ...

Ralf Meier 12-Nov-23 5:13am View

Please post your complete code - use the "improve question" widget inside the question.
While testing your actual code-snippet I found that the Cursor isn't set to standard when leaving the modified control. So you are doing something wrong - to make a suggestion I msut understand your issue ...
Another thing : if you want a reaction from some of us you should use the "reply"-widget at the comment you are refering ...

Ralf Meier 11-Nov-23 19:19pm View

it could be helpful if you tell us (me) something more about the protocoll.
To get something similar work I would also let it 1st work inside the UI-Thread.

Ralf Meier 11-Nov-23 19:11pm View

Please explain me what the sense of these code is - for you.
The behaviour you try to achieve (for me) is standard-functionality of a RichTextbox ... (without this code-snippet)

Ralf Meier 9-Nov-23 13:01pm View

Ralf Meier 22-Aug-23 5:29am View

Perhaps you could create a Component or a customized Control - but for this it is necessary to know what the goal is. That was the reason for my last comment ...

Ralf Meier 21-Aug-23 17:35pm View

you've got an answer from Dave - but for my understanding : what is the final goal you are facing with this question ?

Ralf Meier 21-Aug-23 4:29am View

could you give an example how the moving-path of your machine-part looks like ?
I think there is a way with customized controls and using more parts of the graphics-unit - but for this I need more infomation ...

Ralf Meier 19-Aug-23 11:13am View

I suggest you should declare the _person outside the method GridviewToObject. In your sample this object only exists inside the method ...

Ralf Meier 27-Jul-23 7:51am View

But Ahmed has written that the Color comes from the Author-Settings and not from the comment itself ...

Ralf Meier 27-Jul-23 7:48am View

I'm sorry ... not really ... because I don't have your Document and also not your code.
But a suggestion : try to follow the sample from StackOverFlow ... and also : what does this Porperty deliver to you ?

Ralf Meier 25-Jul-23 6:29am View

you might be right - with that I wasn't sure ...
bur nevertheless - the OP could make an Error-Handling which is even better as nothing (like mentioned by you)

Ralf Meier 23-Jul-23 14:54pm View

very good approach ... +5

Ralf Meier 20-Jul-23 15:41pm View

The provided code is more or less nothing - I can't imagine that it is the work you have done ... what are you awaiting from us ?

Ralf Meier 18-Jul-23 11:41am View

and for your new problem the answer is the same : look what the Debugger tells you ...

Ralf Meier 18-Jul-23 11:40am View

Don't post an answer as a Solution - for this we have the widgets "have a question or comment ?"

Ralf Meier 17-Jul-23 8:44am View

... and your actual code is ...?
Have you took a look with the Debugger to see what is happening inside your code ?

Ralf Meier 17-Jul-23 4:41am View

back to your method :
sender is an object - if you want to use it you must at first assign it to a variable which type it the original type of the sender - in your case Employee. Object is the base-type from variables and it doesn't consists of items and so on - it's more or less a kind of pointer ...

Ralf Meier 17-Jul-23 4:38am View

complete agree with you ... but I suppose we are (he is) lightyears away from using the binding ...

Ralf Meier 17-Jul-23 4:36am View

I see your code and in my opinion it's wrong at all - have you ever used the Debugger to see what is really happening ?
But at first : please explain what you want to happen inside the handler-method ?

Ralf Meier 17-Jul-23 4:24am View

of course all your links are very useful for the OP - but I suppose the problem he has is using the List and especially the items in it in the wrong way.

Ralf Meier 17-Jul-23 4:20am View

... but now the original Code is gone ... lets go back to there because there is the part which throws the exception because you make a complete wrong assignment. Please improve this question with that code and perhaps made corrections ...

Ralf Meier 16-Jul-23 16:55pm View

... but when the OP doubleclicks a Excel-Cell then the Action must come from a VB-Script inside the Excel-Workbook which catches the Event from the Cell ... or am I wrong ?

Ralf Meier 16-Jul-23 8:41am View

Perhaps (but I'm not sure) your mistake is that you try to change the item and not it's value - that depends perhaps on the type of the elements of your List.
You should provide more Info - also what kind of exeption do you get and where ...?

Ralf Meier 11-Jul-23 5:16am View

It's your part do do - this was my suggestion because it was the first thought when I saw the code and whats happend with the string ...

Ralf Meier 10-Jul-23 16:26pm View

Take a look at the Split-Method for strings. With that you can seperate it into the single values inside an Array. I can imagine that it makes it mujch easier ...

Ralf Meier 7-Jul-23 16:57pm View

And what have you done to realize those calculation ?

Ralf Meier 5-Jul-23 2:37am View

In Germany we say "ohne Fleiss kein Preis" which means "without working on it you have no success".
Thats your decission - I and everyone else here could only make suggestions ...

Ralf Meier 4-Jul-23 18:41pm View

okay .. but that is a mistake in your Application and NOT in the answer of OG - a Solution could be not to use the same Method for both actions ...
And there is no reason to downvote this Solution because it's answer is quiet right.
+5 rom me to correct it ...

Ralf Meier 4-Jul-23 18:33pm View

List is a Class-Object with own Methods and Properties.
One of it's Methodes is "Add" - with that you enter a new Entry into the List. Also you have other Methods like "Remove" and so on.
It's Property "Count" delivers you the Number of Entries inside the List.
As I allready pointed out : you should engage yourself with that - List is a very mighty Tool ...

Ralf Meier 4-Jul-23 12:18pm View

I don't believe ... For your issue the best approach would be, as allready mentioned by me, the Solution with the List (of String).
Perhaps you take a look on in and engage yourself with it ...

Ralf Meier 4-Jul-23 5:43am View

In my opinion the memory-usage comes from the underlying class. In your Solution your dimension of the BankNames-Array is done outside it.
What happens if you later (in same months or more) go back to your application ? Or someone complete different ? I suppose that is difficult to realize the/your layout. Also in my opinion it is complete against OOP - but that are my 2 cents ...

Ralf Meier 4-Jul-23 3:00am View

I#M sorry - you version may work ... but it isn't a good way to realize that. I don't agree with it ...

Ralf Meier 4-Jul-23 2:58am View

the Solution from Dave should also work if you use it in the right way. But a List is different to an Array - that is something you should realize ...

Ralf Meier 3-Jul-23 16:04pm View

As I wrote at my suggestion - it is complete different --- but very much better ...

Ralf Meier 3-Jul-23 16:03pm View

that isn't possible - sorry.
In this case you should think about the suggestion of Dave - but that isn't an Array - that is an empty suitcase which could be filled with your need. Perhaps you engage yourself a little with that ...

Ralf Meier 3-Jul-23 16:00pm View

the difference is that the class now has a defined array in it which will be delivered with the Property. Using a Porperty like a public Variable isn't a good style at any time. It's allways better to use the Getter and the Setter Methodes of it ...

Ralf Meier 3-Jul-23 15:54pm View

See my Solution - it is exactly like that ...

Ralf Meier 3-Jul-23 15:50pm View

I must add a last comment :
Inside the Solution of Grame_Grant was added a Link for explaining Arrays. When you take a look at that Description there you will see that my Explaining of Array-Dimensioning was complete right. An Array (4) consists of 5 Elements (0 .. 4).

Ralf Meier 3-Jul-23 4:25am View

this discussion goes to nowhere - inside my Visual-Studio an Array(1) has 2 Elements ... and my code-part 3 doesn't fail.
That has nothing in common with unallocated memory as mentioned by Richard - it simply works and as I remember that was every time like this.
If you create an Array (10) it is the same - it has 11 Elements and I can access the Index 10.
If wwe speak about Collections or Lists there is a Difference ...
So ... to finalize it : if no one can explain me why my code works (and my development system) I'm out of this discussion.
And ... also thanks for downvoting (to 1 !!!) my Solution ... very very nice ...

Ralf Meier 3-Jul-23 2:35am View

where is the difference between your suggestion_1 and my suggestion_2 ?
after dimensioning the Array to 1 it consists of 2 elements (Index 0 and Index 1) - I don't know if that is equal to C# ... but at VB it happens like described ...

Ralf Meier 3-Jul-23 2:29am View

I'm sorry, Bradley ... but I see absolutely no difference between the Solution 2 and 4 and I also can't see why one of these Solutions is better than the other because both are using the same mechanism.
In fact it is no Problem to give an additional answer to an old question if it's different and/or a complete new approach - but in this case I see more the point which is called "Reputation Points Hunting" - and that is a very often used practise in this Forum. Perhaps you take a look at the "community" and there to the "Spam and Abuse watch".
But also for me there is no need to discuss this further - sorry ...

I agree with @Grame_Grant - somewhere in your code (perhaps the Countdown-Display) forces an Invalidate of the complete Form.

Ralf Meier 26-Jan-23 18:04pm View

without understanding the sense of your question :
- take the Byte-Part (for example 1A) from the string

- divide it by 2 or do a shift right
- rebuild a string-value from the new byte-value

What we do here is helping those who stuck at a specific point. Perhaps it is possible to help you ... but without some code from you and a idea what you want to have it is impossible (for me) - or in other way : we don't sit in front of your PC and can't see what is happening.
The concept for game rules (generally) are the rules of the game itself - if you want to create a kind of KI it depends primary also on this rules ...

Ralf Meier 12-Jan-23 11:46am View

I don't see a question ... or is it the ask for "do the remaining work for me" ?

Ralf Meier 9-Jan-23 16:49pm View

If ypou don't understand what I mean I must ask you for your knowledge. Did you understood any of that what I've written ?
For example derive or customizing ?

Ralf Meier 6-Jan-23 13:22pm View

Sorry - this code doesn't help ... :(
What I would do :
- create your owh (customized) Picturebox which derives from Picturebox and has some additional Properties as :
- Back-Image (which as to be seen when the Picturebox is not activated)
- Active-Image (which is to be seen when the Picturebox was activated)
- Active-Image-Code (same Images has the same code)
- Status (tell you that the Picturebox was activated)
and also additional Methods as :
- Change_to_Active_Image (when Clicked change the Image from Background to Active)
- Change_to_Back_Image (when called change the Image from Active to Background)
- now assign the Images (randomly) to those Pictureboxes and give them a code for identifying
- if you click the 1st PB memorise it and it's code
- when you click the 2nd PB memorise it and it's code
- compare the both codes - if they are matching switch them to unvisible
- if they are not matching change both to the Backimage
- the game is over when no PB is visible

Ralf Meier 5-Jan-23 13:43pm View

The Description from Griff for me is quiet clear - but it seams not for you ...
I suggest you provide some of your code because without it it's complete senseless to give more advises.
I suggest also that you read the solution from Griff once more and this time more carefully ...

Ralf Meier 13-Dec-22 11:54am View

OK ... very good ... that seems to be exactly (or nearly) what you have asked for ...
Since I am a kind of collector it is very interesting for me - who knows when I need something like that by myself ...
Thanks for your Reply :)

Ralf Meier 12-Dec-22 11:17am View

Thanks for the Sample - I will take later a deeper look on it ...
The posted Solution I found (on CP) while looking for a complete different approach ...

Ralf Meier 12-Dec-22 8:05am View

I have posted a way to a Solution for you ...

Ralf Meier 12-Dec-22 7:02am View

you could be right - it seams to be a mix between C# and VB.Net ... (but perhaps it could be modified)
But now I have a little time - so I will try it by myself. If I get a Solution I will post it for you ...

Ralf Meier 11-Dec-22 11:56am View

it looks good - you should provide it as a Solution ...

Ralf Meier 11-Dec-22 7:56am View

Complete correct.
Wheen I do this I normally scan the Controls-Collection for the names and add them to a Listbox inside my Form (so I could see the Names) - often the Name itself says all about the Function of the Control. If not you should do the same with the Types.
I'm very interested on your progress - so please hold me informed ... ;-)
And of course if there are further questions ...

Ralf Meier 11-Dec-22 6:54am View

As I wrote before :
You must use Reflection. Each Control has a Controls-Collection which holds all Sub-Control inside it (if there are some). Now what you have to do is : iterate through this collection and find the Name (and by this also) the Reference from the Tabcontrol. But perhaps (that could also be possible) the control is the TabControl (that means derives from it).
If you have the TabControls Reference you can add a new TabPage to it.
How familiar are you with doing something like this ?

Ralf Meier 11-Dec-22 6:35am View

Basicly I can imagine that the Solution from Mike is working - but there is a lot of knowledge neccessary to do this.
In the past I often modified the windows-delivered Editors but mostly to exclude given controls or functions - but I suppose that the other way round is also possible. For this you need to know the content of the UI - that means : what is the Name of the Tabcontrol and where is it located. Now you can perhaps add another Tabpage to it with the content you like to have. The functions of your new Tabpage must deliver the selected value to the Return-Parameter from the original UI - for this you need to know how it is done. I think that this is the most problematicly part (and I have no idea how it could be done).
If you want to have this special function ... why don`t you create you own ColorEditor which works like you want to have ...?

Hi ...
I'm glad to see that you have accepted the solution.
If this answer is working for you please be so kind and rate it.

Ralf Meier 17-Oct-22 2:27am View

Basicly, when working with a Com-Port, you should allways know how the communication-protokoll is. That means : what is the request und what is the answer. If the answer is variable you normally get this information from one of the first bytes of the answer.
In the moment I don't know how to give you more help ...

Ralf Meier 16-Oct-22 10:24am View

I'm not quiet sure if I had complete understand your problem - but perhaps :
If you use the DataReceived-Event from the Com-Port you should realize that this Event is fired with the first incomming Character - that means that you should check if all the Characters you are awaiting are inside the Receive-Buffer - that may be a time later.
Baiscly you could check how many Chars are inside the Buffer before do anything further ...

Ralf Meier 29-Sep-22 6:10am View

You should give much more Information - either about your control and also about the code you are using ...
Without this it is impossible to give useful advises - sorry

Ralf Meier 11-Jul-22 3:57am View

you should 1st identify what is one weighting-sequence - I suppose that each time you get a string from your unit it is the actual value. So I suggest you not append your textbox (richTextBox1.Text += ...) but assign to it (richTextBox1.Text = ...).

but ... what device you are using - I think that your "problem" is to be solved with paramters of the device ...

Ralf Meier 19-Apr-22 8:43am View

do you know the Specification of the Line you are searching for ?
Or the other way round : with your 1st sample you work with the line (1,1 - 2,2 - 3,3) - who says that this is the right line ? the right line could also be 1,1 - 1,4 and then the 2 points between are wrong ...?
the same with the 2nd line ...

Ralf Meier 19-Apr-22 8:38am View

Hi Eddie,
I have to say that I'm not quiet sure at the moment if the KeyPressed-Event is exactly the right approach (in the moment I'm not able to look for it). If it is right you will get the Enter-Key as possible KeyCode-selection. Otherwise you should look for what Richard has mentioned - the KeyDown-Event. Also there you have EventArgs which gives you much more Info than the "Standard"-EventArgs - but you are allways able to select that because all Special-EventArgs are deriving from this class ...

Ralf Meier 15-Mar-22 8:00am View

To answer your question in your reply (to Griff) : Yes i did ...
Perhaps you haven't had any idea - but in this case you should give much more information. You did nothing of that - no ground to start from ...
And ... for me the answer you gave to Griff was abusive ...

Ralf Meier 15-Mar-22 4:17am View

Think about what you write and don't be abusive ...
Of course you will get an answer if you give information where you stuck - but what you have done is : "do the work for me ..."

Which Property do you mean exactly ?
Do you have set the DesignerVisibility to DesignerVisibility.Content at the Property-Attributes ?

Ralf Meier 27-Aug-21 15:14pm View

I agree completely with Bill because your own desciption says exactly what has to happen - you only have to create a code from it.
To give xou a little start :
- the Selection of you Combobox should depending on the Seletion assign something.
- the Button, if pressed, has to work with that what was previously assigned.
Perhaps you give it a try ...

I asked you to describe what should happen - as you see by the answer of OriginalGriff your code itself makes no real sense.
So what should happen ?

Ralf Meier 28-Jun-21 5:14am View

Perhaps it is easier if you try to describe what you want to achieve ...

Ralf Meier 28-Jun-21 4:13am View

If none of the given answers are matching to your issue you should think about the description of what you want to do.
Perhaps you should improve your question with much more information - for me it sounds that you want to have sub-items to your items ...?

Hi Griff,
the Brackets ? Right ?
But you are right - today it's really very early in the morning ... ;)

Ralf Meier 20-Jun-21 3:36am View

It is like Patrice allready has mentioned : you should set a Breakpoint (perhaps at the line 'TextBox2.Text = ArrayTag(2)') and look with the Debugger what REALLY is inside ArrayTag - I suppose that you will see that there are only 2 Elements inside ArrayTag (Index 0 and 1). Give it a try ... ;-)

Ralf Meier 11-Jun-21 4:08am View

Initilized means that the Variable "exists" - if we speak about a Variable. If we have a Class-type you only have a placeholder - that doesn't mean that the Variable is instanced.
If you want to have a defined content you have to do it. If we speak about a (more or less) Standard-Variable you have to assign it. If we have a Class-type it could be done with the Constructor (to Default) or with a customized Contructor (as in your sample above) to special values.

Ralf Meier 11-Jun-21 1:28am View

As Richard wrote in the other Solution : if you want to have a defined content you are responsible by yourself to ensure that.
I would never let a Variable unassigned - but that's my 2 cent ...

Ralf Meier 10-Jun-21 4:22am View

I'm sorry - I refered to your Class-Example ...
The Struct must be initialized when used as a Variable (perhaps with the Constructor of the Class which uses it)

Ralf Meier 20-Apr-21 3:42am View

to get a useful answer it's very necessary to give information about your issue AND information where you stuck.
Apologize ... but for me your question is complete un-understandable and senseless ...

Ralf Meier 15-Apr-21 8:44am View

If you have a Question then ask it as Question and do not add it as Answer to an existing Question ...

Ralf Meier 28-Mar-21 6:50am View

not quiet correct ... I suppose.
As I see each incomming sequence is ended with a LF - I haven't seen that before.
Your Solution might work (in the moment - but could make an error in future). You look if your incomming sequence contains a LF - I would change it to that your incomming data must End with LF ot ENQ or EOT. Also you should work only with that String-part which is ended with one of these Chars ...

Ralf Meier 26-Mar-21 13:43pm View

Not really. It depends on your Communication-Protokoll.
The Serailport has the Property BytesToRead. This Property gives you the Information how much Bytes are actually inside the Buffer.
If your are awaiting (for exmaple) 10 Chars and there are only 6 in it you should exit the Method - with the next incomming Char the Event raises again.
If the Buffer contains more than 10 Chars - but you need only 10 - you should not ReadExisting - read only those which are needed by you.

Another Approach could be not to use the DataReceived-Event. You could also use a Timer (for example each 100 ms) and check there if the count of Chars are matching to what you need.

Give it a try - you know much better than I what is needed and when ...

Ralf Meier 19-Mar-21 9:04am View

There is no real difference to the code from the OP. It must work with .Value as well ...

OriginalGriff exactly wrote what your problem is - your Exeception says : "expected Typed is DateTime" - you give it a string ...

I don't understand the calculation within your provided code. I suppose you try a kind of scaling.

What are the "many changes" you made to your Application ?

Ralf Meier 11-Mar-21 9:07am View

Why don't you listen to what Richard wrote to you ?
Don't you know the difference between those Types of Variables ?

What I don't understand :
You have a String why those values inside. Why do you first convert it to an Array and after this want it back as a string ?
If you can answer this I suppose you find the real answer by yourself ...
sorry for that ...
