And you are sure about you are the one who control the handshake?
E.g. be sure you disabled xon/xoff, rts/cts etc?

And btw. baudrate you don't need to bother about with 'USB CDC'. USB will take over here.

Do you have question or only an order to code for you?
Trying to do by yourself is widely known as learning.

*lol* just was about to ask the same question :-)

I suggest to use type 'application/octet-stream' or 'application/zip', this because 'sample.xlsx' and here especally '.xlsx' points to a zip file (xlsx are zipped excel files). You can open an .xlsx with e.g. 7 zip to see the details.
I hope it helps.

At first I thought what a useless answer, I'll vote something between 1...3.

But after reading it again (and again) and especally the statement 'Always a pointer is only a pointer to some memory and NOT the memory to which it is pointing.' made me give it a 5 ;)

I see, thank you very much. And btw. my 5 for your answer.

And that means?

Implement a minimal DHCP Server, there are a lot of examples available.

You can use also rax or rbx, which are 64 bit

Similar should be tested for sqrt of negative values.

?

And, any success?

How about google? ;)
https://blender.stackexchange.com/questions/129674/apply-transformation-matrix-to-existing-mesh[^]

It us much more simple to use transform(matrix)

Great one, *thumbsup* and my 5

Of course a 5

In c++ there is a 'logic'. The logic is to evaluate parameters from right to left. But of course, I would not rely on, that every compiler does it the same way.
Therefore, your statement 'The take home message being: do not use expressions like this.' is very ok but unfortunately I can't give you a five here for a comment ;)

And I don't see a logic for that result :-)

My 5. And yes, 'static' does not (should never) have any effect.

You mean from right to left, right?
And I wouldn't rely on all compilers doing it this way. Altought it seems most do it ;)

Try qualified name in where: WHERE T1.DocumentNo NOT IN ...

Use COALESCE instead of ISNULL.
See here: SQL Server COALESCE() Function[^]

Looks not like a mistake. Looks more, your PC reads then and when faster than arduino can send.

See here: https://pubs.acs.org/doi/full/10.1021/acssensors.8b00340[^]

I would try backup/restore the database.

Sould not be the sequence like this: DecodeJpeg -> WebPEncodeRGBA -> WebPDecodeRGBA?
My wild guess is, that DecodeJpeg adjusts the 'W32 BGRA' to 'WebRGBA' under the hood of 'QImage'.

What happens if you use quality of 100 instead of 80? Or as alternative use directly WebPEncodeLosslessRGBA

Maybe a read of this will help: Run-time type information - Wikipedia[^]

Ok, we see what you tried. Now the questions:
a.) What part you are not happy about
b.) What you expect?

No problem. But you mentioned you tried TinyExpr. That means, you can use it and write the code to varying the variable in a loop 'in a structured way' and let TinyExpr evaluate. That comes nearly to a solver.
Sorry for my English...

There are a lot, I'm sure.
But meanwhile I had a closer look to your equation and if '%' means Modulo then of course there will no solution. This because (x+38)%4 has no chance to give a reminder of 30 ;)

There are a lot of solver examples: Google for "solver c++". Solver in very easy words means for your example to solve the equation (x + 38)%4") - 30 = 0 by varying parameter x (also called root search).

You are welcome

From PHP: sqlsrv_num_rows - Manual[^]
sqlsrv_num_rows, Return Values
Returns the number of rows retrieved on success and false if an error occurred. If a forward cursor (the default) or dynamic cursor is used, false is returned.

Oh yes the "+=" i did not recognize. My 5.

Looks like you only have to wait long enough until the random number num1, num2 and num3 will be the same...

And your code is?
Use 'Improve question' Editing a Question[^] to show your code.

'I have a faulty mouse that sometimes double clicks when I only single click': How is about to buy a new mouse?

Pragmatic approach: SUM(Quantity * Price) / SUM(Quantity)

I tried it and it does not return the one for which only one entry exists ;)

Looks like you tried nothing. Read this: Python String find() method - GeeksforGeeks[^]

And to get true or false simply compare the return value >= 0

But what if no second exists and there is only one?

You are right, I was wrong :(

Wild guess, something like this: COUNT(*) OVER (PARTITION BY xyz) xyzcount and then WHERE seq = 2 OR xyzcount = 1

Better you post the complete SQL statement. Use 'Improve question': Editing a Question[^]

Now you tried it with the code you mentioned.
Where is your question?
What do you expect and what your code so far delivers? And with which result you are not happy?

'Not from me': Oh yes from you. Please have a look to that crap piece of code. I'm pretty sure you have commented such crap for a new member much more directly :)

Trash only

The Question and the answer is simply stupid/bs. Why you are protecting a member because it is simply a long time meber? A beginner would get only ridicule for it... :(

I don't understand why you support such bull sh*t

Sorry, I'm very sure I'm right and you are _very_ wrong.
And yes, I claim you don't understand the basics of logical comparisons!

[Edit]
And you even don't get that it is better to reply to a comment using the 'reply button' of a comment

No idea what you mean with 'Bit bounds checking'. The code I suggested is simply: simple and logical and correct ;)

The code you provided shows a lack of knowledge on boolean math ;)

Think about what happens when temperature == Min_Temp and also the case when temperature == Max_Temp ;)

This should do the job:

if (temperature < Min_Temp)
{
....
}else if(temperature < Max_Temp)
{
....
}else
{
....
}


No, no. You gave the correct background info ;)

Looks more like Base64

Do you mean Base64 Encoding/Decoding?

Are Sequences mayba an option?

Looks like you mix up the things....
In your main you instanciate parent_class parent; and derived_class derived1; and I think that ends in your confusion.
These two instances are completely unrelated instances and each of these instances hold it's _own_ data.

The instance parent has private1 equals to -1 and private2 equals to -12.
While the instance of derived1 has the values private1 of 20 and private2 of 32 (both stored in base class/in other words members of the base class) and additinal the member private3 of 45, member of the dreived class.

Again: The instances of parent_class parent; and derived_class derived1; are completely unrelated variables.

Read Solution 1 and try to understand the hints there. As a detail for the future: Replace you boolean upwards by an int direction where -1 means downwards +1 means upwards.

Last but not least: When you reply to a comment, use the 'reply' button of the comment to which you like to reply. This keeps the writer of the comment you answer informed ;)

try this:if(diff>0) {
upwards= true;
elevetorMover.Start();
}
else if (diff < 0){
upwards= false;
elevetorMover.Start();
}
else{
MessageBox.Show("You cannot remain in the same floor");
}


Yes but you don't set it to upwards when last direction was downwards.
And again: You don't start the levator in case it goes downwards.

On a first glance:
a.) In button2_Click_1 in case it goes down you don't start the elevator in case if(diff<0)
b.) In the same method make sure to always set the direction upwards to the correct value. This wheter it goes up or down.

For this you have the methods [void] OnStart([string[]]$args) {
Write-Host "Service started"
} which will called

Same idea here.. but I was unsure. Have my little 5.
[Edit]
And holy whatever...
also the else needs to be intended? How I hate that language. How i love it for numpy :)

Now I'm far away from knowing phyton... but is it not only the break in line no. 10 which needs to be 'inserted' ?
How I hate languages depending on intendations :-)

What I understand when reading the documentation is: A score of 1 is perfect. Therefor 0.6 is something away from being perfect ;)

I was assuming your js runs in a browser. And from what I understand CORS is handled by the browser and only by it. But yes, I don't know so much in that field, was anyway only a wild guess *blush* ;)

[Edit]
I'm pretty sure that @RichardDeeming can solve that :D

Maybe a CORS issue?

I have added your correction. Thanks for accepting the answer.

You are welcome. Which of your two answers?

You are welcome.
'tunneling is probably above my pay grade': I don't think so, give it a try ;)

What exactly? Nit pickings or Send vs. Post ;P :D

Try something like this. I will not google it for you ;) And of course set the right parameters where I simply put a 0
[DllImport("user32.dll", SetLastError = true, CharSet = CharSet.Auto)]
static extern bool PostMessage(IntPtr hWnd, uint Msg, IntPtr wParam, IntPtr lParam);

private void button1_Click(object sender, EventArgs e)
{
PostMessage(new IntPtr(), 0, (IntPtr)0, (IntPtr)0);
}

[Deleted]... wait a moment

Send: pinvoke.net: sendmessage (user32)[^]

Post: pinvoke.net: postmessage (user32)[^]

Because it is a broadcast message the HWnd parameter does not count (I think). simply pass 0 or null....

The arguments are exactly the same as for SendMessage. Or where I'm wrong, where is the problem?

Thanks, but for this somebody downvoted you :(
Use 'Improve Question' on you original question to add such information.
... and it looks like you did not try to replace SendMessage by PostMessage :(

Wait wait... Don't post things like this as an answer. There are crazy nit picking members around here which will downvote something like that (as you can see :( ).
Use 'improve question' in your original question to post information like this.

And btw. looks like you did not replaced SendMessage by PostMessage....

Can you please post the code of the app based on the CPs article code?

Btw. I will delete my answer, because it does not looks like it helped ;)
Think also about to delete what you posted as answer to prevent you from downvotes.

I'm groping in the dark, most probably my lack in English :(
Also I'm not shure what code you are using now. The one in your question or the one of the article.
But maybe simply remove screenSaverProcess.WaitForExit(); will help?
Another thing: Running that kind of code from VS can also have some side effects.

I don't understand what you mean with this (keep in mind I'm not native English speaker ;) )
What keeps open? Your app?

Same as for SendMessage:
PostMessage(new IntPtr((int)SpecialHandles.HWND_BROADCAST),
WM_SYSCOMMAND,
SC_SCREENSAVE,
0);
I'm something confused. Above you wrote it works and I should submit it as an answer.
Now it looks for me, nothing works?

I would say this is a subject for a new question ;)
[Edit]
I'm not clear about what the problem is. But it sounds like you need to use PostMessage() instead of SendMessage()

Did you try it? If yes what is the problem?

Can be I don't understand your request. But for me it looks like you need something like this: Preview events - WPF .NET | Microsoft Learn[^]

Maybe this helps with some ideas: Programmatically Turning on the Screen Saver[^]

That sounds good (for OP), please take over :D

Thanks for this. I'm not experienced with XPath, that's why I did not post a solution but only a comment. At least I tested it before posting ;)

1. XmlNodeList xnList = xml.SelectNodes("Etichetta");
should be XmlNodeList xnList = xml.SelectNodes("PrintDymo/Etichetta");
2. Barcode and Materiale are Attributes of _individual_ Campi nodes, which at least for me makes not big sense.

You showed what you got, that's good.
But you do not explain/show what you expect.

I see...
const { parse, format } = require('date-fns');
const frenchDate = "2 avril 2023";
const parsedDate = parse(frenchDate, "d MMMM yyyy", new Date(), { locale: require('date-fns/locale/fr') });
const formattedDate = format(parsedDate, 'dd-MM-yyyy');
console.log(formattedDate); // Output: 02-04-2023


Btw. use correct reply button ;)

const frenchDate = "2 avril 2023";
const dateObj = new Date(frenchDate);

// Get day, month, and year values from the date object
const day = dateObj.getDate().toString().padStart(2, '0');
const month = (dateObj.getMonth() + 1).toString().padStart(2, '0'); // Note that month value starts from 0
const year = dateObj.getFullYear();

// Combine day, month, and year values into the desired format
const formattedDate = `${day}-${month}-${year}`;

Anyway a bad approach. Try to stay on formal date/time.

My guess is: If you draw your shapes etc. in Panel.Paint Event you should be fine.

Guess from where I got that:
When you take a picture in the emulator, it's stored in the emulator's file system. The path to the file will be different than in production, where the file will be stored on the device's file system.

Regarding your code, Environment.SpecialFolder.Personal is the correct way to retrieve the path to the app's private directory in the emulator. The private directory is where your app can store files that are specific to your app and won't be accessible by other apps or the user.

To find the exact location where your image is being saved, you can use the Android Device Monitor tool that comes with Android Studio.

Here are the steps to find the file location:

Start the emulator and make sure your app is running on it.
Open the Android Device Monitor by selecting it from the Tools menu in Android Studio.
Select your running emulator from the Devices tab.
Navigate to the File Explorer tab.
From there, you should be able to browse the emulator's file system and find your app's private directory, where your image should be saved.
Alternatively, you can use the adb command-line tool to pull the file from the emulator to your local machine. The command would look something like this:

adb pull /data/data/your.package.name/files/image.jpg

Replace your.package.name with your app's package name and image.jpg with the name of your image file.

Keep calm. It will adjust with time ;)

Not sure what is in question here...
I remember, that I marked an accepted article publication from @V_Cento as 'Wrong type (tip, blog, article). The article was original approved by cp staff.
I hope that is not the issue...

Anyway: There was no downvote involved from my side

Thanks ;)

You are right. Sorry, I didn't checked the details :(

According to CP staff, there is no problem, answering the own question ;)

I'm aware now I'm becoming something off topic to ask a question in a comment.
Nevertheless I do it ;) :
Is it a bad praxis to 'POST' e.g. a zip file as content type 'octet stream' to a rest service?

Thank you very much again.

Hundred thousand thanks. I can only give my little 5 :)

Share your code if you expect help. Use 'Improve question' to add your relevant code snippets.

Sorry, that it did not helped.
Maybe you can add a hex representation, what your c# receives as filename. This, because I think to remember, that I fighted with a similar issue for USB driveres, where the W32 API should deliver WideChar but always delivered Ansi (and this even I used the xyz_W api)

Have a look here: IOCTL problem sending string value to usermode[^]

And, where is the problem exactly?

Thank you very much for your feedback.
I tested it indeed with c++. So have my 5 then.

I'm only on the first case a = (*p)++;

You wrote
- take the value stored in p and increment it by one
- then save the resultant value in variable a

But it is, because post increment
- take the value stored in p and assign it to a
- then increment the value (*p), which at least with my compiler does nothing.

Not a thing to worry about I think ;)

The correct answer. 5, even pre inc. I don't see in the Question and will most probably confuse OP to mention it :-)

The question was about a=(*p)++; and not a = *p++; which is a different thing ;)

Not really correct and no vote from my side! a = (*p)++; means
assign the value stored in p and afterwards increment the value stored on p.... and that increment disapears then in the nirvana ;)

Just visited the docs, see my edited answer. At least for MSSQL FROM is optional. Surprise, surprise for me :-)

Sorry, I'm out of ideas :(
I trust you, that the grid does not show only the last and only one column :-)

Only big speculation, try to trim the string you get from the grid. I mean .ToString().Trim(' ')
And yes, can't be the reason because you explained, last record will be deleted.... headache ;)

Is Serial of type integer or is it char(xyz)? If char, maybe some blanks in the database and the grid does trimm them?

MSSQL or MySql or what? Anyway strange that a SQL engine acceppt your delete statement.

have my five ;)
but still strange that the last record has been deleted :-)

Apart from that your delete sql is wrong I see no problem. But it is curious that you have success deleting the last row ;)

From my point of view it should be, notice 'FROM' DELETE FROM Articol WHERE Serial = @Serial"

I see. Thank you for the vote.

You have one dictionary were the values (of the key/value pair) is a list. Therefore to print that you have to loop over the value- list.
That's it.

From my point of view you have one list too much. But anyway to get the expected result with your current code it would be something like this (take care intendation much probably destroyed in the comment):

for i in operand:
for key, value in i.items():
for listValue in value :
for listListValue in listValue:
print(key, listListValue)


Would be nice you give a short summary how you solved.

Ok then. But then document.getElementById("the_id").innerHTML can get the specific detail?

I guess it would be forwarded anyway to DebugOutput which can be observed with tools like 'Dbgview.exe'. But it is only a guess.

I'm completely noob on that. But my speculation is, that only input fields will be posted back and therefore are available with $_POST

Publish your code in question in your question. Nobody here is keen click a link.

"what is the error in my code it is not printing the answer."
Which of the about 5 ones?

Start here: Replace # include <bits stdc++.h> by
#include <iostream>
#include <vector>

After all that, have a look to line 27.

And so on and so on.

Reported as 'not a question'

And what should be the result in case src= '0303'?
Btw, makes sense you show your code.

There is also that old OutputDebugString in combination with "Dbgview.exe"

'This same exact call works with C# in with no problem': Payload is completely different.
What is, if you use exactly same payload in VB which you are using in c#?

Finally after five updates, I hope it fits :(

[Edit]
@AVG_SALARY as INTEGER does not really make sense, but let us take that for finetuning...

Sorry from my side for the confusion from my side. I mixed up the syntax of mssql with another server.
For mssql it needs to be more something like:

...
DECLARE @AVG_SALARY INT

SELECT @AVG_SALARY = (SELECT AVG(SALARY) FROM EMP_DETAILS WHERE DEPARTMENT_ID = @P_DEPARTMENT_ID)

UPDATE EMP_DETAILS
SET SALARY = SALARY + SALARY * 0.25
WHERE SALARY < @AVG_SALARY
AND DEPARTMENT_ID = @P_DEPARTMENT_ID


Yes, but don't foget to include also DEPARTMENT_ID in the UPDATE WHERE clause. I updated my first comment, see there.

And it is very ok to ask back, no need to be sorry ;)

a.) What is the error message if there is one?
b.) You can't get the average that simple by AVG(SALARY). Most easy you select avarage in advance.
Something like SELECT AVG(SALARY) FROM EMP_DETAILS WHERE DEPARTMENT_ID = @P_DEPARTMENT_ID INTO @AVG_SALARY

After that use that @AVG_SALARY as parameter for the update SQL.
UPDATE EMP_DETAILS
SET SALARY = SALARY + SALARY * 0.25
WHERE SALARY < @AVG_SALARY
AND DEPARTMENT_ID = @P_DEPARTMENT_ID;

Thank you very much for this explanation. Appreciated very much.

Sorry, but for a 13 year member you should know how to comment to a answer or a comment.
What you posted here is not an answer it is only a comment to Richard's answer and therefore should be handled like that. E.g. by Is it possible to send a fraudulent email?[^]

Sorry, but then you have to define 'how many text' need to be equal, to show 'equal'. Not that easy...

And please, take care with your answers. Try to answer to the member with the correct'reply' button. It makes things easier ;)

What is the problem?
Barcode 1 -> Text1
Barcode 2 -> Text2

bool isSame= Text1 == Text2;

What means 'html design popup' ?

Sorry, again hard to understand. Try to use google translate (or similar) to translate the question written in your native language into English ;)

Furthermore: '... text inside barcode equal to other barcode ...' has a very wide range. What means equals here? One word, two words ...?

Is it not for windows at least, that a named mutex Global\\xyz does what op is expecting?

What boolean value you would expect if e.g. for c.BaseCostShareProjectPerson?.Hrn == p.BasePerson?.Hrn the left or the right hand side or both is null?

To be more precise, what do you expect what the results should be
1. undefined == defined
2. undefined == undefined

And moreover, what should happen when concatenating such results with e.g. or, what should be the results for ...
1. undefined or defined
2. undefined or undefined

I have some problems reading and understanding you first paragraph. Maybe you should rewrite that...
Apart from that: How is about decode the barcodes and compare the results?

I suggest to arrange the columns for both parts of the union statement to have _exactly_ the same order. After that try it again.

You should post the section of code that causes this error.

No vote from my side ;p

But the information is correct. 5.

Quote:"What I'm not understanding is why are we setting inputDir at 0th row, 1st column?"
inputDir is the direction. And therefor it is not set to the 0th row, 1st column. It holds _the direction_ of the next movement.

Thank you very much Sir ;)

Please tell us, which method returns a '0'.
I think in case a connection can't be established it would be more 408 'Request Timeout'. But to be honest, here I'm not quite sure ;)

But I'm pretty sure @RichardDeeming can help on that

FYI: http status code 0 does not exists and also not for 'older' courses ;)
HTTP-Statuscode – Wikipedia[^]

Please tell us at what point from what method you get that '0'.

Yep. Then this is the problem I think. Now it is up to you to figure out, why the server respond with an empty string. Btw, what is the http response code the server replies for your request?

Then please show what the server responses exactly. This to get a chance to help what's wrong

What is the json data you receive?
For me it looks you get an empty string and therefore json parsing fails.

You are very welcome.
1) You checked allready for '== NULL'. For me it confuses more if you check again for '!= NULL'.
2) Because your original code fragment shows 'C++' I assumed you are working with 'C++'. Now I recognize you are working with 'C'. Then of course you are on the right path with 'malloc'. Sorry for that confusion.

[Edit]
An additional comment to 1)
If a test for equal fails, it can only be unequal. Therefore testing again for unequal - at least for me - makes no sense and does confuse.
I hope it helps ;)

[Edit1]
Quote: ' Is there any performance difference of one over the other?'
I don't think so. I would assume that today's compilers will optimize that 'double check' anyway.

I'm too lazy to go trough all this code. From experience here, I would say you code is perfect. A 5.

On a first glance:
In your addData you forgot to set next_node in the last existing item to the new added element.

I would say: if(strcmp(argv[2],"output.wav")!=0) instead of if(strcmp(argv[2],"output.wav")==0)

Wow! 5

Are you asking for 'multi level' sorting?

google for 'Authentication' and also maybe for future for 'Authentication vs. Authorization'. It should give you an idea what you need.

Little bit tricky with a loop, but working ;)

Happy new year you too ;)

Does it work or not? If not, what is wrong?

So what you have to do first is to define all the rules. So far I can see them it is
a.) Numbers in a line
b.) Numbers delimited by '/' (except the number is at end of line?)
c.) What more? E.g. delimited by whitechars like space, tab, ...? E.g. 'AlphaPart 3051 ,'

Have a look to your SQL statement e.g. here: https://codebeautify.org/sqlformatter[^]

And be aware of SQL injection when using user inputs directly as part of your SQL ;)

The first step will be to refactor the code where decisions will be taken on e.g. button captions.
After that you simply can localize the GUI elements while loading the page.
