With main missing it appears you've built the program as the wrong kind of project. main() starts a command line program, so did you try to build it as a Windows program (which must start with WinMain)?

To build a command line project, go to File -> New -> Project; in Visual C++ select Win32; in Templates pick Win32 Console Application. At the appropriate point switch precompiled headers off. Then add daginda.cpp to the project and comment out the existing tmain function, and it should build OK.
