It is because you access memory that you shouldn't. You probably read or write at an invalid address (0x0000000 or an unitialized pointer). Use your debugger to see where it happens.

Probably you would be writing to some invalid memory location that you have not yet initialized,
Try using the debugger to get to the root of this problem.
Somethings seem HARD to do, until we know how to do them.

Or you are probably trying to deallocate block of memory which was allocated by another dll

Hi all
In a dialog call proc the following lines never allow me debug the block contained as below...
#ifdef _WINDU_SOURCE
case WM_ERASEBKGND:
{
InvalidateRect(hDlg,NULL,FALSE); // ensures painting of buttons in front of background bitmap
if(GetDlgItem(hDlg, IDB_KEY1))
DrawKeyBackground(hDlg, IDB_KEY1, IDB_KEY_MAP_1);
return 0;
}
#endif
I put F9 at DrawKeyBackGround() function but debugger disabled it and I could not debug this function . What is this _WINDU_SOURCE ?

It's a pre-processor macro which means that it will be checked before the compilation. If you cannot debug there, it simply means that the macro is not defined thus no code is generated for this section.
|
|
|
|
|
I do not understand . In fact the function inside the block is very important so that the bitmap itself is BlgBlt there . So if code is not generated for this function then the bitmap could not be displayed - but it is displayed !!

This code is for the WM_ERASEBKGND, not for the WM_PAINT message. So, probably there is something also for the WM_PAINT message.

Thank you. But i dont want it to be redirected into a file. I want to copy it directly to the buffer in the program at runtime.
Is it possible?

Sorry for posting an incomplete question.
My question is...
I want to run another exe from my application as console and want to catch the output into a buffer of this application without redirecting into another file.

Well , whether you launch another application or not , whatever in output buffer can be read if you read the IO stream .
Note :
Use CreateProcess() (if you want to posses the handle of child exe and destory it ) or ShellExecute() to launch another exe

You have to implement registry modifications needed for enabling the sub menu item in your InitInstance or whatever is the init function and when the exe exits remove the modifcations aas before ...

If you are referring to files with a .doc extension, see the following registry key:
HKEY_CLASSES_ROOT\.doc
Picture files and music files have various extensions. They are also located in the HKCR hive.

I have an edit control in a dialog. This dialog has bitmap image over it. I have handled the OnCtlColor in the dialog class. I have set the background mode as TRANSPARENT for the edit control.
When i scroll the bitmap image on the dialog is also getting scrolled. I need to avoid this. The scrolling show happen without moving the bitmap on the dialog. How do i achieve this???

I'm not exatcly sure what you mean.... But I've used this method to stop my dialog from scrolling from non window scrollbars.
if you have a OnHScroll or OnVScroll for your dialog ...
try returning from the function if pScrollBar is not NULL before doing any of the switch statements.
void CEdrumMonDlg::OnHScroll(UINT nSBCode, UINT nPos, CScrollBar* pScrollBar)
{
if(pScrollBar != NULL){return;}
switch (nSBCode).........
.......
}
