You're using the same binary on both Windows XP and Windows 2000, and the same version of the MFC DLL?
Is the Windows 2000 system running Service Pack 4? The DLL Help Database[^] indicates that Windows 2000 SP4 shipped a new version, 6.0.9586.0, of mfc42.dll. If you're compiling with MFC 6.0, supplied with Visual Studio 6.0, this might (potentially) be causing the problem. An even newer version, 6.0.9782.0, ships in Visual Studio 6 Service Pack 6.
Exactly what problem occurs? Do you get an ASSERT failure, or an error message? Is the behaviour consistent across Debug and Release builds?
If you get an ASSERT, what source file and line is listed? If you get an error, what is the exact error message?
[edit] Are you using a CSingleDocTemplate, a CMultiDocTemplate, or your own class derived either from one of those or directly from CDocTemplate? [/edit]

Hi, I have some functions written in C# I want to use in Win32 API program (C++ used).
How can I do it. If someone can give me a sample code or direct to the some tutorial.
Thanks

The 'easy' way - use the regasm tool to export the C# class to COM. Use COM to load the C# code and call it.
The harder way - decompile your C# code with ildasm, add the appropriate declarations to the IL to get the CLR to generate flat exports (as in a traditional C DLL) and recompile with ilasm.
The really hard way - investigate the CLR hosting interfaces.

Does anyone know whether it's possible to recognize right clicks with the CButtonST class developed by Davide Calabro? I know that you can declare a function
afx_msg void OnButton(UNIT nID)
in order to handle left-clicking a button, but can a similar process be applied for a right click? If anyone knows how to do this, please let me know.

Is there a way that you can attach a command-line parameter on the end of an url? I want to send someone a hyperlink that will open up an .exe - that part works fine, but I also want them to be able to send 2 parameters, (the name of two text files). Is there any way to do that?

just append the variables to the end of the URL. THey will be ignored if not needed.
so if the URL is "http://this.com/that.exe" just change it to "http://this.com/that.exe?VAR1=foo.txt&VAR2=bar.txt"

A while back I read something telling me that there was a way to call a base class function from the child class; does anyone know how to do this? Thanks!!

or simply function() if the child class do not have a function with the same name where the base class declare this function to be virtual...

What's the best way to write HTML code to a file? Is it simply to write the raw tags or are there some libraries around that simply this? Thanks in advance.

Just write tags like if you were writing some kind of text. save it as you would do with a text file. is the same, but put the .htm extension.

wouldn't you prefer declare me as a bool& or even a bool* instead ?

Depend on his religoius philosophy; whether me destructs when leaving life's scope. (That's almost nausiatingly poetic in a nerdy sort of way. Don't think of it as dying, think of it as going out of scope.)

As a bool, it consumes 1 byte. As a bool*, it would consume 4 bytes. Correct? If so, future posts would therefore be 300% larger than necessary!

ok for the bool*, but that was an expectation for getting me out of the scope. but what about a bool&?

Michael Dunn told me "Use the CCS_NOPARENTALIGN style".
I've used it but what I win with this is that I can set up the height free, but I am not able to put 30 pixels from left for example. I use this function to call the CToolBarCtrl:
my_tool_bar.Create(WS_CHILD|WS_VISIBLE|CCS_NODIVIDER|CCS_NOPARENTALIGN, CRect(0, 110, 80, 80), this, IDC_MY_TOOL_BAR);
If I set up like this:
my_tool_bar.Create(WS_CHILD|WS_VISIBLE|CCS_NODIVIDER|CCS_NOPARENTALIGN, CRect(30, 110, 80, 80), this, IDC_MY_TOOL_BAR);
The top fails... I don't know what to do...
Please, if you could put me an example of how to create a CToolBarCtrl with no top or bottom alignment into the window... I want to draw it into a CRect from the Window.
Thanks in advance !!!

Well, I solved it:
my_tool_bar.Create(WS_CHILD|WS_VISIBLE|CCS_NODIVIDER|CCS_NOPARENTALIGN|CBRS_NOALIGN|CBRS_FLYBY, CRect(30, 110, 80, 80), this, IDC_MY_TOOL_BAR);
Thanx anyway !!

Hi all! I had a question concerning visual c++ 6.0. I'm coding a card game in Win32 (no MFC) and am trying to fill an edit box on a dialog window dynamically with child controls. What the program does is it queries the current directory for all sound (.wav) files and, for each sound file, inserts three child controls in the edit box on one line. The controls are, from left to right, an edit box for the caption the user wants for this sound file, a play button to listen to the sound, and a second edit box for the name of the sound file.
I'm inserting these into an edit box because, since the sound list is obviously dynamic and of arbitrary length, I'd like to utilize the scroll bar on the edit box. The problem I'm running into is that the edit box is unaware of anything being added to it. I'm calling CreateWindow to add these controls to the edit box, with the handle to the edit box as the parent parameter, and the lines of child controls for the sound files fill up past the depth of the edit box without the scroll bar being activated.
One solution I tried was to insert a newline character into the edit box for each line of controls I added. This solved the scroll bar problem, but when you scroll the edit box the display gets really confused as to what to display (the controls or the "\n").
Any advice is GREATLY appreciated.

I've never heard of anything other than text being added to an edit control. Do you have an example that shows this?

I'm envisioning a list control with two "columns," one for caption and the other for filename. Each of these can be edited in place. A "Play" button would reside next to the list control and would act upon whatever file is currently selected.
