Thanks, but the problem was only solved when I used static linking instead of dynamic linking of multithreaded C library

In that case, you either deployed a debug build, or didn't install the CRT
libraries properly on the target machine.

Hi all
I am launching from my C++/Cli console application a child process using System::Diagnostics::Process class.
This child process throws an exception and the damned "do you wish to debug" window .
Is there any way to trap this kind of exception in my code?
Many Thanks
ManuStone

exceptions are a stack mechanism, a parent process has no access to a child process stack.

Hello,
I have a problem with a mixed mode dll. In this dll it is a class (#pragma unmanaged) which contains a singleton. But now I have a porblem during unloading the program. During unload the program I became allways the message "Unhandled exception at 0x7c812a5b in Test.exe: 0xC0020001: The string binding is invalid".
I have searched already a lot around the internet but there are a lot of messages regarding this problem. The most have only a solution for VS2003 and not VS2005. I have tested all what I have found.
It is really easy to reproduce this problem. You need only a mixed mode dll and a unmanaged class with an singleton (the problems happens also with automatic atexit registration and also in manual)
Best regards
Hansjörg

Have you tried freeing the Singleton prior to the process exiting?

How I should free the singleton prior to process exiting? It is freeing automatically and I don't wont an explicitly call to a function.
Best regards

Just as a way of testing to see if it solves the problem, why not?

Make an assembly and then reference it from another project.

What is the assembly you mean? Is it a module(.def) or dll?

I don't understand. Certainly you know how to make a button with a single letter for the text label right?

I have connected my application with the Microsoft Access database, via ADO.NET OLEDB. I can insert and edit data, but I have no idea how to search the database, or just to select some record and to insert that into some string.
Here is a example for inserting a new record
String ^strData = "INSERT INTO Continents VALUES('Abcd',12345678,87654321);";<br />
OleDbCommand ^cmdDatabase=gcnew OleDbCommand(strData, oleDbConnection1);<br />
cmdDatabase->ExecuteNonQuery();
Please help.

Hi i'm wondering if the console could be viewed in windows forms?
I'm not sure what the line would be to view the console.

Because there isn't one since you just took the code and put it in a Windows Forms application.
gman2008 wrote: I don't want this information to be displayed to the user on the form but as a background job in a windows console.
Ok but it doesn't need to be a Console. You can just create a 2nd form and display it there. David Crow has sort of explained that already without the 2nd form part. Based on your apparent beginners level you will likely have some difficulty doing this in any way you attempt to do it. You probably want to do some reading[^] on creating multiple forms, particularly Modeless forms.

First off - a bit of background:
For a project i'm working on I need to distribute objects to groups of users based on a number of different algorithms, my idea was to store the state for each algorithm inside their respective functions using static variables. This was to be done in C# until I realised C# doesn't support this functionality but i know C++ does. Sooo ...
Does Managed C++ support static variables inside functions in the same way as standard C++ does or is it a limitation of the CLR that means this functionality isn't available in .NET?
Thanks
Richard

Never mind, I refactored my code so each algorithm is inside its own class and can now use static class members to store current state.

That is the right way to do it, whatever language you choose. State belongs to an object,
not to a function.

A .NET application? That's what this forum is for. If not you are in the wrong forum.

Hi,
I am a "hobby" programmer with a lot of familiarity with pre-.NET C++ programming in Windows, but not too much with .NET. I've written a Form based Windows application and want to set it up so that the app monitors changes to clipboard data. Therefore, I need to call the Win32 functions SetClipBoardViewer, etc. (Or is there another way to do this in .NET that I haven't found)?
As far as I can tell, I need to use the PInvoke mechanism with declarations something like:
[DllImport("User32")]
static int SetClipboardViewer(int hWndNewViewer);
(I would think these should be HWND's, but the above is what I found.)
My problem is that I don't know the correct declarations for these functions, and I don't know how to set up the calls to them. I found an example for C# that shows how to do the whole process of setting up a clipboard monitoring application, but I really want to learn how to do this in C++.
Any help would be appreciated!
Thanks,
Tom
