Hi All,

while i am try to close the Application, at that time i am getting an error message. The Error message is displayed in popup Message Box.

"Windows has triggered a breakpoint in PlantView.exe.

This may be due to a corruption of the heap, which indicates a bug in PlantView.exe or any of the DLLs it has loaded.

This may also be due to the user pressing F12 while PlantView.exe has focus.

The output window may have more diagnostic information."

I am dubegging my application in Visula studio 2008.

Please any one can help me...

Why is a crash an expected/allowed behaviour if the user presses F12? Suspicious | :suss:

I would track down what happens when the user presses F12.

Simple: fix the error!

The message box with the error message is, to my knowledge, something unique to your application. There's no way for anybody else to explain to you why the error occurs.
To me it's clear that the application comes equipped with a bug that some developer could not solve that happens e.g. when the user presses F12. The developer also "explained" it to be quite normal behaviour since he/she put it in the error message text.
It could be a way to end/terminate the application by pressing F12, but in that case there should not be an error message popping up, so I assume this is a bug.

You have to debug your application.
A good starting point would be a message handler called when the user presses F12 and work your way down. Find out what happened that made this message box pop up by asking the user what he/she did and particularly whether F12 was pressed or not.

ICopyHook COM interface is one option, but not sure if it catches file copying using dos commands.

To answer your query, with MFC alone, you cannot do something like that. And ICopyHook as such does not work with files, but only with folders. So you'd better off be doing a little more research on it.

Start reading up on File filter driver[^]. You will have to write one for your needs.

Also, see if The UltimateToolbox File Watcher[^] is of any help.

Please Suggest....
///CODE TO Draw Text
GetClientRect(GetDlgItem(ts.hWnd, IDC_STATIC_BMP1), &r);
hdc = GetDC(GetDlgItem(ts.hWnd, IDC_STATIC_BMP1));
SetBkMode(hdc ,TRANSPARENT);
SetTextColor(hdc , RGB(0,0,0));
DrawText(hdc , szTempBuffer, -1, &r , DT_SINGLELINE | DT_CENTER | DT_VCENTER);

There is nothing like an API for this, you've got to devise logic for this purpose, probably invalidate that region where the text is printed. Or probably set the text color (Dc.SetTextColor()) to background color and then print the text again. Don't forget to test this well cause there may be cases where the edges of text are still visible.

Some other options that came to my mind is to use FillSolidRect/FillRect with background colors, but then there will be problems when you have gradient backgrounds.
