The first error indicates that you need to (re-)create your pre-compiled headers. See the Compiler section in the Project settings.

The second error indicates that the linker cannot find the definition of cD25Dlg::GetThisClass. Possibly because of the first error, possibly because one source module did not compile.

I added a 5 vote to your solution, so I hope it really is now the "above" solution.

Right click on the project in solution explorer.

Navigate to >Properties >All Configurations.

Open the tree for C/C++ and then >Precompiled Headers. Select Use {/Yu}

Fill in the Header File field- yours should default to something like pch.h

Make sure your header files contain pch.h and that your #include is edited correctly

Verify you have a pch.cpp file in project. Create if not present. Should only contain #include pch.h at the top
View Properties >AllConfigs on this file. Select PreCompiled Header Create {/Yc}. This will bind to only pch.cpp

Verify that #include pch.h is the first line of all source files.
