When I open 2nd form wrom 1st one with "Show" and then messagebox from 2nd form, then after closing 1st form the program hangs up. The problem is because messagebox is opened as a dialog from 2nd form. What should I do to close every window after closing 1st form?
I'm opening 2nd form with:
System.Reflection.Assembly assembly = System.Reflection.Assembly.LoadFrom("WindowsControlLibrary1.dll");
object obj = assembly.CreateInstance("WindowsControlLibrary1.Form1",true);
obj.GetType().InvokeMember("Show",System.Reflection.BindingFlags.InvokeMethod,null,obj,null);
Thanks for every help

So you have access to the control library or make a reference to that dll and then Just :
WindowsControlLibrary1.Form1 myForm = new WindowsControlLibrary1.Form1();<br />
myForm.Show();
this will close it whenever the main form closes.

Thanks but this still hangs up.
And I would prefere not adding references (I wont to load additional .dll's when program start).
I explain again:
|----| |----| |----|
| 1 | -> | 2 | -> | 3 |
|____| |____| |____|
I open form #1,
then from form #1 I open form #2 (Show),
and from form #2 I open messagebox #3.
When I close #1 the other two are still working.
Then if I close #2 and #3 the program is still running and to be seen in task manager.
Hope I explained everything this time.

Well, since Form holds the references to all the other forms, it can't close until all of its child forms close. Which, in your case, can't happen because your Form2 is stuck waiting for a mesagebox to close.
What you'll have to do is implement a status mechanism on Form2. In Form1's closing event, it has to check with all the forms it opened and ask each one if it is safe to close, and if so, then it can close itself after it closes each of the child forms.
Each of the forms that your Form1 opens has to implement some kind of method to track its own status. For instance, if Form2 opens a MessageBox, it has to update a flag in its code that says that it is "not OK to close". When the MessageBox finally returns, then it can change that flag to something that means "OK to close". When Form1 iterates through all the forms that it opened, it calls a function on each form that checks that flag. If any of the forms returns that it is NOT ok to close, then Form1 has to abort closing itself.

How can i use application in win98. I used .NET Framework 1.1. I have instaled in win98. When i use that program, i got System.NullReferenceExpliction. Under xp, i don't have a problem. I have programd in C++ 2003
|
|
|
|
|
What exactly are you doing? It's not really clear if your using managed c++ or where the exception is being thrown.
Anyway some things like EventLogs don't exist on windows 98.
Have a look at this list[^] of supported features.
|
|
|
|
|
I Don't Use eventLogs
I use RegistryKey Does this support.
I din't find anything at that link
|
|
|
|
|
Some registry keys that exist under an NT Kernel (NT/2000/XP/2003) don't exist under 98. Your code should have been written to check return values before trying to use them. You'r going to have to go back and write some tracing code into your code so you can see where this error is taking place.
Without knowing anything about your code, what you're doing, where the error in your code is occuring, ..., it's impossible to tell you what's wrong. I mean, all your told us is, literally, "My program works on XP, but breaks on 98". There's absolutely nothing we can do with a description like this.

You're kidding, right? You don't pay me enough to debug your code for you, especially a chunk of code this long. I'm telling you how to find it yourself. You hope it helps me?!? No. Help yourself...
Let me show your what your NOT doing. I told you to check your return values before you try to use them. You're not doing that. For example:
RegistryKey *pKey = Registry::ClassesRoot;
pKey = pKey->OpenSubKey(S"ArtMoneyTable\\Shell\\Open\\Command");
Object *pValue = pKey->GetValue(S"");
Did OpenSubKey actually return a Registry object or is it null? You're not checking this. You're just assuming that it worked and returned the object you expected. Now, your next line immediately tries to use the returned object, calling its GetValue method. If OpenSubKey returned null, which exception do you think will be throw when you try and execute?
Object *pValue = null->GetValue(S"");
I'm not saying this is your codes' problem, but this is a glaring example of why your code is failing and you can't find where the problem is. Always check your return values before you try to use them!

Thanks for your attention.
Currently I am working on a image processing program for PPC (using C#), yet there are two problems remained to be solved:
1.  Rotating an image. Compact framework doesn't support the methods such as "Image.RotateFlip" or "Graphics.DrawImage(Image, Point[])", so I need to implement the rotation function completely by manually coding. Therefore I need an algorithm, which doesn't invoke any special system-provided method, to perform image rotation.
2. Saving an image. The compact framework doesn't support the Image.Save method, so I have to find another way to save a Bitmap object into a JPEG file.
Any kind of help will be greatly appreciated. Thanks.

I have code in C++ using Editbox, appending \r\n to each line to make a new line.
In .NET, using Textbox, I actually SEE the \r\n and everything is on one line.

Thanks.
BTW, I was using editBox.Text += "\r\n" and it wasn't working.
Using Environment.Newline works great.
I've never used the @ prefix in literals.

Hi,
I created a backup file containing sources around 2.5G. The compressed CAB file size is around 1 G.
Now when I am trying to extract the contents of the cab file, I am getting an error FDICopy() Failed: code 11[User aborted] while it reaches one particular file.
I tried viewing the list of files in the cab, I could see all the files I had asked to be archived.
Even when I tried to extract using Winzip, the winzip also encountered problems at the same file. I was trying to extract the cab file onto my D:\. The following was the error message -
"CAB file is continued on disk as in drive D:\...." "D:\ is not a CAB file..." "Error processing multi-part CAB file"
Pls help me as I need the cab file contents!
Thanks, Sheela

Hello, I am designing a very basic video game, and I want an image to move relative to key presses. This image is on top of a background image. I use picture boxes, however there is a rectangle surrounding the image I wish to move, and it does not look right. Is there a way to make it so that the moving image appears to be part of the background image, so when I move it around? Much like any video game out there with characters that move. Thank you very much

Don't use picturebox ,but use Graphics.DrawImage() as it will draw over the back ground and when you call this.Refresh(),It will re paint the back ground and you casn after this call immediatly draw it again in another location.
|
|
|
|
|
Is there a specific way to call that function; I have tried this so far:
Bitmap* MyImage;<br />
System::String* image = "Resource/wiggle.gif";<br />
<br />
MyImage = new Bitmap(image);<br />
Graphics* Dr = new Graphics;<br />
Dr.DrawImage((dynamic_cast<Image*>(MyImage)),50,50);
however I get errors. Thank you very much for the help you have given me thus far.

Hi, I'm developing a stand alone system for Pocket PC. Currently facing problem on how to create database for Pocket PC. I using VB .net to develop the system. Anyone can help here? Thanks in advance!

The SQL Server CE tools on the PDA have a simple Query Analzyer tool, you can execute sql or visually design the tables with this tool.
|
|
|
|
|
Thank Dan_P for your reply. Just try to confirm with you. The SQL server CE tools is pre-installed on the PDA or it needed to get the software install in it.
|
|
|
|
|
|
Also the first time you deploy an app that uses SqlServer CE, it installs it.

This might not be the best forum for this question but I hope someone will be able to answer it anyway.
I have a bunch of nunit tests that I want to run. The problem is that they fail if run them all. If I run them one by one they work fine. These tests tests some sockets network code. The network connection is done using a static object. This means all tests use the same network connection object. I thought that the tests run one after the other, but it seems they run in parallell sometimes. This has the effect that a test connects to the server and starts doing what the test does and then another test opens a new connection with the effect that the state needed in the first tests is lost, and thereby causing the first test to fail.
So the real question is how NUnit runs the tests? Does it run them one after the other or (atleast to some degree) in parallell?
