I use the VC .NET in my EPOC development. Our company doesn't have lic. with old VC 6.0.
How to resolve all problems with using VC 7.0 project engine.
Create from mmp --> dsw project by makmake.
Convert to the Visual C++ 7.0 project format.
Open Project properties and do two settings

Code Generation
Minimize CRT in USE ---> YES
Enable C++ Exceptions ---> NO
Buffer Security Check ---> NO
Command Line
Additional Options

Then compile and enjoy VC .NET IDE

Then I create with C# .mmp - > VC .NET .vcproj wizard for convert and
use it for direct generation project.
