There are two important things to do when adding C code to a C++ project:

1 - Select all .c files, right click to Properties, C++, Precompiled Headers, Precompiled Header and change "Use" to "Not Using Precompiled Headers".

2 - Open every .h file that relates to .c files and add at the beggining extern "C" { and close it with } at the end.

Remember that c code go in .c files and C++ code go in .cpp files.

What do you mean by embedding a project into another project?
What is the output of the C project - EXE/DLL/???

You use the source files in an MFC project by adding them as .C files into the MFC project.
If the output is an EXE, you can use ShellExecute/CreateProcess to invoke it from the MFC project.
If the output is a DLL or LIB, you can use as you would normally from the MFC project.

Is that what you wish to do?
If so, right click on the MFC project in Solutions Explorer and select Add -> Existing Item and select the .C and .H files.

Check if it works if you do a rebuild all.
Check this link - http://msdn.microsoft.com/en-us/library/zww6zdh7(v=vs.100).aspx

Just add Stdafx.h in your all .c files or donot use "pre-compiled headers". You can change this via properties->C/C++/precompiled Headers in VC++

Don't add StdAfx.h into .c files. StdAfx contains links to C++ classes.

But do set the properties to not use precompiled headers.

As previously replied i hv done this but aftr that getting error of C2471....
i think some thing is going different as you are thinking.So please try to give more to more options to me.Thanks

You may try to delete all files in the Debug/Release output directories, start your VS, and rebuild all. If this does not help: Which VS and Windows versions you are using (C2471 is a known error with VS2003 and Windows Vista/7)?
