Changing from MFC to ATL is a complicated procedure as you have found out. You don't need to go through the pain. You can make a MFC COM object although that has it's own pains.

I plan to copy all the MFC Class ,Including GUI Class ,such as Frmae,View, to the Atl Project .And it can be complied successfully. Then I can further modify the Atl project based on that. I will add some interface in Atl project to call function instead of the automation message loop . In this way , I think I could let the Atl dll run in VB GUI,with his own GUI (Frame ,view,Dialog ) just loaded in memory and not shown. This is my idea . What do you think of it ? I just want to get a general structrue ,and then I can modify the Atl code into more simple project,such as change Frame,view into other substitutes. In this way ,I can achieve my goal. Expecting your advice. Now I have copied all the MFC Class ,Including GUI Class ,such as Frmae,View,from the MFC Project to the Atl Project .And it can be complied successfully. But when I attempt to register the DLL I get the following error: Debug Assertion Failed! Program: C:\WINNT\System32\regsvr32.exe File: D:\Program Files\Microsoft Visual Studio\VC98\MFC\SRC\APPCORE.CPP Line: 85 Expression: ASSERT(AfxGetThread() == NULL); So what does this really tell me and what can I do to correct it? Any ideas???

There is no tool that I know of, because it is *difficult* What kind of MFC code do you want to change to ATL ? It is a simple COM object, ActiveX control, or full blown MFC app ? In any case, I wish you luck V
