Question

.
I found sample called “Creating a COM Server Using a Text Editor” in MSDN.
http://msdn.microsoft.com/en-us/library/2wad1c0e(v=vs.71).aspx

It compiles fine from command promt, but not from Visual Studio IDE.

I decided to move this project to Visual Studio.
I have created new project (File>>New>>Project>>Empty project) and add MyServer.cpp file to “Source Files” and MyIncludes.h to Header Files. I got following error after I tried to build project:

1>------ Build started: Project: Myserver, Configuration: Release Win32 ------
1>Compiling...
1>MyServer.cpp
1>.\MyServer.cpp(26) : warning C4581: deprecated behavior: '"apartment"' replaced with 'apartment' to process attribute
1>Linking...

1>Myserver - 1 error(s), 1 warning(s)
 ========= Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

How to solve this problem?

Answer 1

The translation errors told you need a entry function in an EXE module.
you must define a main(…) function as the entry, otherwise is an invalid EXE since there is no startup point.
Simply, you can create an console window project for IDE, or just add main(…) manually as I said.
