Well, great :) Perhaps it's tine you upvoted my solution ?

For some reason, I am getting 2 email notifications for each of your comments.

Hi, I wanr to help you if I can !

Right now, I need more specific information on what your problem is.

I suggest you post a new question which includes your current code and an example of output that is not what you expect.

Please do not send the same comment twice.

cheers, Bill

What have you tried ? And what solution are you after ?

Please be very specific.

+5 amen !

a node can have only one child node ? that's a linked list ?

what is the reason you need to traverse up and down at the same time ?

That indicates some kind of install error: you've got to identify the exact dependency that is not implemwnted, and remove the older whatever that is invoked now. Sorry I can't be more helpful.

but, your code does not cause an error ? Try putting a break-point at the start of your code, then single-step (F11), observing the state of variables.

What happens ... or does not happen ... when you run your code ?

While a TabPage doesn't expose an 'Enabled property at design-time, you can set it at runtime in code, and, the TabPage can still be selected.

see revised solution.

if this is C#, why are you using low-level API calls rather than controls on a Form or WPF Window ?

This idea and its code is so confused i suggest you get a good back on C# and study the "basics," and, re-think your design. What type of calculator increments some variable by #7 each time a mouse-click on a button occurs ?

There are lots of examples of C# calculators on-line: study them !

'base ? what is the context here that makes you use ;base ?

I suggest you set your MDIForm size in its code, then use use the Dock Property to make amy one of child Forms fill it.

Name:John,Age:18,Hobby:(text message)
Name:May,Age:17,Hobby:(text message)
Name:Jane,Age:17,Hobby:(text message)

this is the string output you want ? where each "text message" can havew any number of lines ?

from the "builders" of C# Tuples (.NET 4.0 release):

https://docs.microsoft.com/en-us/archive/msdn-magazine/2009/brownfield/building-tuple#id0400060

"The first major decision was whether to treat tuples either as a reference or value type. Since they are immutable any time you want to change the values of a tuple, you have to create a new one. If they are reference types, this means there can be lots of garbage generated if you are changing elements in a tuple in a tight loop. F# tuples were reference types, but there was a feeling from the team that they could realize a performance improvement if two, and perhaps three, element tuples were value types instead. Some teams that had created internal tuples had used value instead of reference types, because their scenarios were very sensitive to creating lots of managed objects. They found that using a value type gave them better performance. In our first draft of the tuple specification, we kept the two-, three-, and four-element tuples as value types, with the rest being reference types. However, during a design meeting that included representatives from other languages it was decided that this "split" design would be confusing, due to the slightly different semantics between the two types. Consistency in behavior and design was determined to be of higher priority than potential performance increases. Based on this input, we changed the design so that all tuples are reference types, although we asked the F# team to do some performance investigation to see if it experienced a speedup when using a value type for some sizes of tuples. It had a good way to test this, since its compiler, written in F#, was a good example of a large program that used tuples in a variety of scenarios. In the end, the F# team found that it did not get a performance improvement when some tuples were value types instead of reference types. This made us feel better about our decision to use reference types for tuple."

just to keep things interesting :)

// Flight is a Class
IEnumerable<flight> testflight = null;

// => true
bool isnull1 = testflight is null;

// ValueType assignment compile error
// (Flight, Flight) testflights = null;

// no compile error
// (Flight, Flight) testflights = default;

// no compile error
// (Flight, Flight) testflights = (null, null);

// no error
(Flight, Flight) testflights = (new Flight("X"), null);

// => false
bool isnull2 = testflights.Item1 is null && testflights.Item2 is null;

testflights.Item2 = new Flight("Y");

// => true
bool isnull3 = testflights.Item1 != null && testflights.Item2!= null;

consider: if testflights is immutable, what will/won't happen when its Item2 is assigned after its first use ?

:) Tony Hoare in 2009, speaking of his 1965 inventor of null: "I call it my billion-dollar mistake…At that time, I was designing the first comprehensive type system for references in an object-oriented language. My goal was to ensure that all use of references should be absolutely safe, with checking performed automatically by the compiler. But I couldn’t resist the temptation to put in a null reference, simply because it was so easy to implement. This has led to innumerable errors, vulnerabilities, and system crashes, which have probably caused a billion dollars of pain and damage in the last forty years."

Thanks ! I expanded the comment you just responded to. The second type declaration in your first example does not have a ? suffix ... accident ?

Since an IEnumerable is by definition nullable, why is the ? required ?

You use DisplayMember and ValueMember ONLY when you use binding. If you ARE using binding: reset them after you add items and reset the DataSource and see if that makes a difference.

As over-engineered as the Pragma weirdness :) ?

One other thought: is there something special about the Tuple Type that is a factor here ? In .NET 4.0, the new Tuple Type is a reference type; then, in 7.0, the "literal" Tuple (ValueType) was introduced.

So, if I'm using a Tuple that I believe is not literal: why, if I just return null, does the compiler shout:

Error CS0037 Cannot convert null to '(IEnumerable<flight>, IEnumerable<flight>)' because it is a non-nullable value type

Clearly it sees the Tuple I define as a ValueType which explains why returning 'default works, but, makes the fact (null,null) works ... strange.

+5 as usual :)

i am wondering if there's a better syntax for returning a null value for a Tuple like this where type T in an IEnumerable<t> is a reference type.

(null, null) does work.

see second example added to solution.

excellent answers are timeless :) ... and deserve up-votes !

+5 very useful !

Have you considered opening an issue on the GitHub site ?

Got it. Wonder how many DFA gurus are using the internet from their Himalayan caves OMG :)

Happy New Year !

Writing a function that takes string data and a list of regex's as inputs, and then executes the regex's in sequence is not acceptable ?

1) ListBox Items are Type Object: when you assign them at design-time they will be Strings.

2) assigning other Types will work if their Type implements 'ToString.

3) your code:

a) every time you create a new "something" inside a method (locally), the reference to that something is lost when the method exits (goes out of scope). That is almost always a bad thing. Define variables of Type something outside the method, andassign new whatevers tp them inside the method: that way you don't lose the reference.

b) I can't tell what you are trying to do with this code: revise your original post, and clearly explain it.

fyi: there is a Dapper area on StackOverFlow: https://stackoverflow.com/search?q=dapper

then, you'll have to do the hard work of finding that icon file in Windows using the techniques I directed you to. but, first, you need to research if Windows includes a 128x128 or larger icon for "This PC" which is a rather unique icon in terms of usage.

https://www.creativefreedom.co.uk/icon-designers-blog/windows-7-icon-sizes/

when/if you have the Icon file, you can display it in a Picturebox:

picturebox1.Image = TheIcon.ToBitmap();

What shows up on screen for a UFO ... a bitmap ? an icon ? a character in a font of picture/symbols ? ?

Unclear: are you asking how to report the state/value of something you did not find, or did not expect to fins ?

Sorry, that's the only thing i can think of ... one way to check that might be to look for some other call to that librarys facilities and see if that, also, breaks ?

Are you sure Win 10/11 does nor have a 128x128 size This PC icon ? You can almost certainly find a graphic you can capture or download on Google:

well, i should not have mentioned "actual code" ... no time to try and decipher other people's complex code ... i'd be surprised if any of us who volunteer here would do that.

Is there any way you can examine the project file, or other app settings, to see if there is a valid reference to 'System.Runtime, Version=6.0.0.0 ?

I wish I could assist further, but, without using your actual source code, I can only think of one more thing to check:

Set break-points after the DataGridView loads, and after you have reset the binding source:

When you hit the break-points: examine the 'Enabled and 'EditMode properties of the DataGridView: see any difference ?

Your solution is logically inconsistent: you say OG's is correct, and it is ... then, you show an example of inserting a Form into another Form's Controls which is not only a bad practice, but also is not relevant to the OP's question.

Voted #1: Putting a Form inside another Form is always a bad idea. In this case the user asks how to load a Form.

+5 a thorough, satisfying, reply !

If this is an assignment, you need to clarify what the assignment actually is.

An assignment to create a structure that emulates a C# Array, but provides Add/Remove functions makes no sense: if you remove an element the indexes may no longer point to the elements they were originally accessed by.

Yes, a possible hypothesis, but, i think we don't have enough information to make that a probable hypothesis. imho, the most probable hypothesis is that the OP is confused.

I've added another comment to the OP's post.
to try and get them to clarify,

Merry Xmas :)

+5 at last the voice of reason speaks :)

Start experimenting and post code here with specific questions.

The date data you show here are not Hjri dates ? Is the problem how to convert to Hijri date ?

+5 what a thorough analysis !

Look carefully at the difference in structure between the first two entries, and the third: variations like that make parsing much more complex,

Is there any way you re-structure the data to avoid inconsistency in format ?

Hi, that partly clarifies the context for me, thanks, but, i define my role here as "educator," and, the idea of helping you write code for some project of which you are a team-member, and. you can't disclose details ... that is not the dance music my feet are keen to move to :)

A general solution to creating a grid of sub-grids, and then efficiently
accessing/selecting "cells" by any arbitrarily defined row, #rows, column, #columns, sub-grid, etc., is an interesting problem ... particularly, if you have nested sub-grids beyond 1 level deep.

In your case, i don't think you'll need to get recursive (deal with more than one level of sub-grids).

Depending on my energy level, I may post some general ideas about one strategy you might pursue.

cheers, bill

Hi, This question is specific enough i can help you with some specific code :)

First, i need to see/understand the code/strategy that creates the grid:

Are you binding the grid to a DataTable; or, creating it directly in a nested for loop ?

And, i believe you omit the case that you need to check for duplicates in a 3x3 sub-grid.

Are you looking for a generic solution for any size grid, or, only a solution for the classic Sudoku 3x3 sub-grids each 3x3 ?

As Richard said, this is pretty simple, but, imho, a program that shows a moving picture until it exits is almost always annoying.

If you want the user to be able to do "other things" while the picture is being displayed, doing that in the SAME Form means you'll have to run it in a separate thread.

you just go ahead and quibble all you need to :)

okay, but, conversion will result in values of the same type ?

Are the numbers represented by the line-strings always of the same Type ? i.e. : Int32, or Double /

Hi, I don't want to see your script code ... I do want to see if I can help you to "pin down/define" what you want in a way that you can get more specific feedback :)

Please revise your original post to include;

The context in which you plan to use Unity ... in WPF, or, WinForms ? other ? What language is your script written in and what is its execution context ... in Unity ?

Describe the structure of your grid; show your code method that defined the Grid,

Sleep well, GMT+7 here :)

Are you using WinForms, or WPF ?

I do know you can use Unity 3d in WinForms, although I have never tried that:

https://docs.unity3d.com/Manual/UnityasaLibrary-Windows.html

I'm having difficulty visualizing what the different size grids are. Let's take the typical 3x3 sub-grid case where each sub-grid is 3x3 cells ... 9 rows, 9 columns, 81 cells.

I assume your script will "seed" the grid with valid initial values ... right ?

Then, the user will input a value in a cell, and you wish to check if that value is valid for the row and column where the value is entered ... right ?

One obvious strategy is to define the data structure for the grid, then pass it by reference to the code that seeds it with initial values ... does that seem relevant ?

"3d ness" ? Are only the contents of the cells 3d elements ? I am not familiar with Unity 3d, so don't know what data structures are available.

Glad you found my response relevant.

"making the 2D Array to hold the selected values for all subgrids."

please clarify what "selected" means here: this refers to cells the user has selected, or cells containing user entered values ... or ?

"I have been able to get a script that generates the whole grid"

what structure is returned by the script ? an array ?

What makes your game 3d ? What does the player see that a 2d flat grid doesn't show ?

"No he is asking how to ensure only one execution of a specific application is running at any one time."

uhhh ... that is what I said.

"You can run any number of copies of an application, even if it contains a singleton class within it."

The OP is talking about an application, not a class: i assume the OP is/has written the App, and the task is to enforce singleton behavior on one machine. Use of Mutex is one standard way to create a Singleton in a context where thread safety is critical.

It's been over 15 years since i touched C++, and i am not aware of current issues in creating Win apps.

hi, we are talking about making an app behave like a singleton class here.

imho, this OP needs education, not having his code written for him.

Any knowledge you have about patterns in the data can be exploited. "Real world data," is often not random.

If the data is "meaningfully" random, then you may be able to omit sorting. Of course, if sorting is a requirement ...

okay, i'll study your explanation when i am more rested. another possibility is: a point may be on more than one segment. to the extent you can narrowly define the results you want, and exclude testing for other cases, you can optimize the code.

in "real world code," skilled programmers often optimize using assumptions about the likely frequency of what types of values the data holds. for example, if i can assume every point is on the line, i can omit testing for that; if the data os organized by magnitude, maybe i don't need to sort.

Different search functions may be used to optimize searching.

Hi, maybe my brain is not at 100% today :) If i think of a horizontal line from x0,y to x1,y then any point on the line can be defined by an x value, and any segment by two x values. In the case the segments do not fully cover the width of the line, there is a possibility that a point can be on the line, and not on any segment.

Other possibilities include: a point is outside the line; or, a segment is "not legal" ... however you define "not legal."

If this accurately describes your "context," please help me understand how the sample data shown "work."

Hi George, I will not engage with this thread further because i see no positive outcome in terms of enduring CP quality, and, my time is limited by vision problems.

Trying to drag information out of you piece-by-piece to try and get the big picture of what you are doing is a waste of time. Amd, i qn not about to go baxk to Win 7 and an early .NET Framework to test your code.

i have carefully verified your code, and Luc's, will not work in a standard VS 2019, C@ 4.8 Console app for reasons i understand completely.

i believe the idea/strategy of using both a Form and a Console is a serious mistake that will result in unnecessary complications.

What i will do, that i think will be valuable for CP in the long run, and will not waste my time, is to post a tip/trick showing what i consider a useful architecture for interactive run-time control of a WinForm's behavior where "control" is defined as response to a well-defined set of commamds, and/or queries.

voted #3; i do not believe this post addresses the key issue for the OP which involves Office interop stuff in ASP.

TreeListView is not a standard WinForm, or WPF, Control: what Control are you using ? Telerik ?

Where's the code for the Buttons click handlers ?

sorry, i thought your name was 'Feorge :)

Hi, follow-up questions (i am unable to duplicate your results, and i get exactly the type of errors i expect to see):

0) what does the user enter into the Console ? a Directory of files ?

1) when you created this project, did you select Console as the project type /

2) did you make any change to the application output type (accessed by the solution property window) ?

3) i notice the show_images method is not declared static: why ?

4) if you would show what the Main method code is, that would be useful

cheers, bill the bloodhound

thanks, George, i will study and test this code today, comparing it to the non-working Console app i am currently testing.

You mention Mono for future use in Linux; please verify this a standa4d C# Console app created on a Win PC.

cheers, Bill

Hi, since solution #3 (as is) does not work in a "standard" Console app i created (specifically to test this code) in VS 2019, using framework 4.8, on a pc running Win 10/64, i am curious to ask you:

0. are you using the exact code shown in solution #3 ?

1. what is your pc's OS, what IDE are you using.

2. when you run solution #3, what do you see on the screen ?

i am always willing to learn :)

thanks, Bill

do you realize that you have an accepted an answer that does not work ?

repost of https://www.codeproject.com/Questions/5315673/How-do-I-fix-this-issue

however: requirement to ignore negative numbers is new.

that's a very gracious response, and very appreciated ! Luc is one of my CP "heroes" :) ... any comments from him are "gold" !

Describe exactly what you want to end up with: a lis of integers ? or ?

We can't read your mind.

i respect that choice :)

OP: "actions I do in the second project must be passed on to the first one."

Your answer is good, but it doesn't address the two-way interaction between processes the OP describes. Of course, that is a very advanced topic !

"Close" means hide, or means dispose of the instance ?

The future users appear in my dreams, voting solutions i have not posted yet to questions they have not asked yet ... #5's :)

imho, the current poster needs an overview of benchmarking; based on awareness of techniques, they can, in the future, make appropriate choices for implementation. Using 'DateTime is a sign to me of lack of knowledge which you address in your post.

Good point ! Is there anything in my post you think is valid, or valuable for this OP, or, for future CP members ?

"the actions I do in the second project must be passed on to the first one."

is having two processes (.exe) running a requirement /

great !

where does the zone information data come from ?

What happens when you run your code ? Errors ? Unexpected results ?

Are you the person who creates the data/text file ?

Why aren't you using a database ?

Hi, "as the words fail me" reminds me of one of my favorite poems "In Broken Images:" by Robert Graves :)

Olease give us a clue what "Cosmos Library" is ... is it one of these:

+5 nice to see you here again, Luc !

When are you going to stop spinning your wheels in semantic sand and start learning how to use the language.

Those of us who volunteer here to answer questions are here to help people learn; not to get side-tracked into discussions of 3rd. party conversations.

Sending multiple comments harping on wanting my opinion is annoying, and inappropriate.

This is not a code writing service. Do some research, experiment with code, ask specific questions related to code you have posted here.

"I guess what I'm asking is what your opinion on what that other user said."

as i said, i can't react meaningfully to a conversation i'm not a party to :)

Hi Tom, i can't react meaningfully to a conversation i'm not a party to :)

My opinions here are deliberately expressed "provocatively."

i prefer a language with very strict strong-typing: is that bias, or preference, habit, or wisdom learned from experience ?

Perhaps you'd enjoy my rant/story about a recent semantic clash i found:

good essay/question ! for the DevX and DevComp components, I'd ask the companies what they are planning.

check the LoadProcess form: is the TextBox on the Form named textBox1000 ? does the error occur when you build/compile ?

i tested the code example before posting it; here's the button click handler for a button on Form1 :

private void button1_Click(object sender, EventArgs e)
{
if (Loading == null) return;

ProJex.LoadingState = "Setting up data adapters\r\n";
Loading.SetStateMessage();
}

is textBox1000 sited in the LoadProcess Form ? is your ProJex,Variables class defined as static and LoadingState field defined as static ?

put a breakpoint on the first line of Form1_Load and single-step through the code, examining what's happening. describe the errors in more detail if possible.

cheers, Bill

inho, this would get #5's if posted as a solu5ion

glad i could assist :)
