It may very well be a problem with different versions of DLLs found in the system. XP probably delivers newer DLLs (MSVCRT et al) than Windows 2000, and if the semantics have changed (bug fixes, etc), then your code may very well be affected.
Can't you just debug the app on XP to see what's going on?

Hi All,
I am very much in need of a program, which I have downloaded a year back. I presume, I downloaded it from Codeproject / MSDN Sample. This program when executed, launches a VB like IDE( Editor ), having toolbox and property windows, from where you can drag and drop controls to a form provided, and we can even write code by double clicking on the controls. I forgot the name of the application, which is supplied with the source.
If any one has seen or downloaded the same, pl. help me by giving the link / the name of the program.
Thanks

Sounds alot like VBLite[^],

And if the paths that I have followed/have tread against the flow/there is no need for sorrow

Hello. I've created a standard MFC app using VC++ 2002.
The toolbar works great and uses CMainFrame::OnDatabase and ::OnTransport to fire-up a child window specific to the button's stated purpose. So far, I have two buttons, one to fire-up the "database functions" window and then one for the "transport functions" window.
BUT, I need to ensure that only ONE child window that does the specific purpose is created when the button is pressed. It doesn't make sense to allow the user to hit a button multiple times, creating multiple "database" or "transport" function child windows... I want to disable a specific button when the child window is visible.
So, I've been trying to work with the ON_UPDATE_COMMAND_UI messages to disable the toolbar button when the child window is successfully created from CMainFrame and then re-enable the toolbar button when the child window is closed by catching the WM_CLOSE message in CMainFrame.
I've experimented with various codings, trying to do the toolbar notifications in both CMainFrame and then, in the two child window objects I have created so far. No real success yet.
Could someone provide me with some source code showing an example of what I need to accomplish?? There's gotta be an accepted way to accomplish this.
Thanks!
Joe

The ON_UPDATE_COMMAND_UI should be called on OnIdle ( IIRC ), so will be called when stuff changes in the UI.
In the ON_UPDATE_COMMAND_UI callback, you can do something like :
...
pCmdUI->Enable( ( IsYourChildWindowVisible() == TRUE ) );
...

That is working A-OK but...
If both child windows are visible, and one loses the focus, the toolbar button of the lost-focus window re-enables itself. In other words, "visible" doesn't actually mean visible but rather "has input focus."
Is there a function to use other than IsWindowVisible that will detect windows that are visible but perhaps don't have the input focus?
Thanks again. Getting there.
Joe
Code in each window's .h/.cpp respective files is (only one shown below):
(in .h file)
afx_msg void OnUpdateToolbarButtons(CCmdUI* pCmdUI);
(in .cpp file)
ON_UPDATE_COMMAND_UI (ID_TRANSPORT, OnUpdateToolbarButtons)
void CHelloWnd::OnUpdateToolbarButtons (CCmdUI* pCmdUI) {
if (IsWindowVisible() == TRUE) {
pCmdUI->Enable (FALSE);
}
if (IsWindowVisible() == FALSE) {
pCmdUI->Enable (TRUE);
}
}
Other file works with the CDatabaseWnd object and addresses that toolbar button message ID and object.

AHA! Got it working properly but unfortunately did have to use two global vars to track the two child window states.
Maybe I'll come back to this problem in the future. I'm burned-out from tweaking it today to work right...
No, I'm not a professional programmer. 
Thanks again Maximilien!

Hello all.
how can I print a very very long string to the printer?
I tried to cut the string at every 50th letter and print it on next line. but it doesn't look nice on the paper after it printed out.. sometime there is a lot of space to fit all the string characters on one sentence.
I want to know if there is a way to find out that the string going beyond the right side of the page?
I'm using CDC.TextOut, StartDoc,EndDoc to print a very long string
Thank you

I''ve made simple COM object, loaded it into Explorer's address space (or what to say) with SHLoadInProc(). When I close my app, the DLL and object is still alaive (of course), so I want to know how to unload it. Hope you understand my explanation.

I use my own Owner-Drawn menus.
Under 2000 I manage to draw OVER window's menu-border and thus have my own menu-border.
Under XP with Flat Menus, XP decides to draw the border AFTER I draw my menu and thus it overrides my border and I get a white-border.
I want to disable FLAT menus, but only for my application/menus, is this possible ?
thanks

Hi,
B&W BMP files are stored in PocketPC. These files have to be run length encoded(RLE) and only the data bits(except the header and fileinfo) have to sent to com port.
Does any one have idea?

Thanks for your reply,
Please can you tell me what technology I have to use and how the control flows. I know MFC. Do I have to use COM+ or ATL in this. Please suggest me how I have to program this application.
