Using VB4.0 with VC++4.2

With the added new features in VB4.0 in being able to build OLE servers, which duties do you think should be delegated to VB and which to VC? I am in the process of converting a VB3.0 app to a VB4.0 based application where I'll be able to use Visual C++ 4.2.

I plan to use VB4.0 for the main application (calling app if you will) and use VC4.2 to create the DLLs, OCX controls, OLE servers.  Would this be the best path, or can VB4.0 handle most of the above?

Also any other information on moving the project from VB3.0 to VB4.0 (with VC4.2) would be appreciated. (ie, VBX to 32-bit OCX).
Thanks,

This is a pretty common question people ask.

Yes, you are right. VB being a 'more RAD' tool than VC++ can be used to develop some jazzy front-ends. It has a much lower learning curve compared to VC++.

VC++ is much faster in terms of speed and the EXE is standalone unlike in VB (which relies on VBRUN*.DLL). I think it is good idea to develop your DLL's , OCX's etc using VC++. Go ahead mate. But a few issues you have to remember.

- VB is not MFC compliant. So If you are using C++ classes make sure you have a wrapper C call to it. This way you will be able to access this export function in VB.

- Avoid returning pointer as VB may not be very happy with it.

About porting issues in VB. Sorry mate, this is a MFC newsgroup. I am not a VB guru.
