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).........

.......

}

Try using CException instead. The exception might not be from CFile.

Check this article[^]. Try using TRY and CATCH macros see if it helps. Unsure | :~

Or have you used catch(...)?

Check out SetErrorMode()
I think you can use this:

<br />
SetErrorMode(SEM_FAILCRITICALERRORS);<br />
...... Do stuff, such as filling up the disk and get the errorcode.<br />
SetErrorMode(0);<br />

resize CFileDialog problem!

For MFC, use TRY/CATCH instead.

I used class CFileDialog in order to open file and save file in my application
But when I select CFileDialog with mode open (flag bOpenFileDialog = TRUE),change size it and close.
I select CFileDialog with mode save as (flag bOpenFileDialog = FALSE).
size of save as dialog exactly the same like size of open dialog when close.
Can I avoid this behaviour?
Please help me!

The file dialog is a system dialog and the size is saved in the registry for each app that uses it. To change the behaviour you have to subclass the file dialog and do all the saving and restoring of the dialog sizes yourself. There are articles about subclassing the CFileDialog here on CP, do a search.

Can you tell me more clearly about key of system dialog in registry .
I have tried subclassing the CFileDialog and set size of it in OnDestroy() and on OnInitDialog() but not successed.
