    Hi Guys, I am wondering if anyone can give me the scoop on this. I am developing a dll file and I have some very good developers telling me that if I develop the dll in Visual Studio 2005/2008 in win32 unmanaged c++ that the dll will not work on win98/me and that it will be dependant on MSVCP80.DLL. They tell me that if I develop the dll in Visual Studio 6.0 that it will work on older operating systems like win98/me and it wont be dependant on MSVCP80.DLL. Now is this true? and if so is there anyway that I can develop the dll using visual studio 2005/2008 so that it will still work on win98/me and NOT be dependant on MSVCP80.DLL? Thanks, Greg

      The only way to develop using VS2005/8 and not be dependent on the C/C++ runtime library is to avoid any references to it. How important is it to maintain support for Win98/ME?

        Dependencies are inevitable. That's why an installation package is created to distribute an application.

          I believe you can statically link the C and C++ run-times into your DLL, so it won't try and load the VS2005/2008 DLLs when it's used. If you do this, you need to take care with memory management of objects passed back from your DLL.

          Java, Basic, who cares - it's all a bunch of tree-hugging hippy cr*p
