Disable/Enable Graphical Pushbutton in Dialog...

I have a dialog that displays records from a MSAccess database using a few static labels, edit fields, and some  graphical record navigation buttons ( |<  <  >  >| ).

I would like to disable the appropriate button according to the record state, ie... If the last record is currently being viewed, then gray-out and disable the Next & Last Record buttons.

I do not want to wipe the image, but display a greyed-out replacement image when the button is disabled.  So, this would not work...

m_IDC_LASTRECORD->EnableWindow(FALSE);

...where m_IDC_LASTRECORD is a pointer object to the CButton class.

The idea is very much like disabling graphical buttons on a toolbar.

Maybe this can be done using the CBitmapButton MFC Class, but the button response is soooooo slow using this class.

Thanks!

I don't see any reason why this won't work.

m_IDC_LASTRECORD->EnableWindow(FALSE);

Try it!

That statement will disable the button, but it wipes the image or makes the image a big block of dark gray.  I want the image to still be there, but in a shade of gray.  This is exactly the same as disabling a graphical button on a toolbar.

When you use that statement with a button that has text, the text will gray out, but when used with an image the button is simply filled with a dark gray.

I appreciate your efforts, but I am looking for a  different method to solve this problem.

CBitmap use four bitmaps.
normal,selected(down),focus ,disable

BOOL LoadBitmaps( LPCTSTR lpszBitmapResource, LPCTSTR lpszBitmapResourceSel = NULL, LPCTSTR lpszBitmapResourceFocus = NULL, LPCTSTR lpszBitmapResourceDisabled = NULL );

hope this function will help you . =)

So, I guess the only possible solution is to use the CBitmapButton Class?

I would love to use this class, but the button press/depress timing is sooooooooooooo slow.
