you have to override WM_MOUSEMOVE and check that the mouse is over your control. if so, then you set the bitmap exactly like you set the first one...

Use below API CBitmapButton::LoadBitmaps

CBitmapButton::LoadBitmaps <br />
<br />
BOOL LoadBitmaps( LPCTSTR lpszBitmapResource, LPCTSTR lpszBitmapResourceSel = NULL, LPCTSTR lpszBitmapResourceFocus = NULL, LPCTSTR lpszBitmapResourceDisabled = NULL );<br />
<br />
BOOL LoadBitmaps( UINT nIDBitmapResource, UINT nIDBitmapResourceSel = 0, UINT nIDBitmapResourceFocus = 0, UINT nIDBitmapResourceDisabled = 0 );

Paresh.

You need to handle WM_MOUSEMOVE for this. At the same time you need to use TrackMouseEvent to caputre WM_MOUSELEAVE.

Using MFC "Object dump" usually refers to an object that inherits from CObject.
Dumping an object means calling CObject::Dump( CDumpContext& ) on that object. The dump function will write relevant information to the dumping context (usually a debug window) about the object's state, memory usage and whatever the developer that created the object thought could be useful.

The object dumping technique is not unique for MFC-CObject-derived objects. It's really about having a base class with a virtual function that can be called during debug sessions.

I am planning to have installshield for VC++ 6.0 which comes along with VC++ 6.0 to install some of the binaries.

All these day, I had been using Installation batch file to create directories,and copying the respective file into the directories and manully making registry entries using .reg file.

I would like to know, is it OK to use Installshiled which comes with VC++ 6.0 or to use the latest Installshield product itself.

What way using the Latest Installshield product is beneficial compared to the version of the Installshield comes along with VC++ 6.0

Is it possible to make use custom action dll & coinstaller in Installshield with VC++ 6.0??

Thanks
