I am learning windows based programming and I am having a hard time following the code on what is going on.  I have been programming in C for a bit and understand what is happening there.  For Example

#include <files here>

int main() {   //program begins
  declare variables
  call functions
  end program
}

very easy to understand.  However, in visual c++ it is a bit more elusive for me to follow.

Can someone just basically go through how it starts, creates window, handles some type of input and exits?  I am not looking for code, but just some kind of flow in more detail then above.

Thanks
Darrell

Are you using MFC? Are you using MFC AppWizard to create your program?

Windows application is based on message loop proccessing messages( notification that something hase happened).When you create windows application you create at least one window and define special function called window procedure callback function to be called every time some message needs processing. Each message is defined by unique ID and has two parameters through which extra data can be passed, This message loop roots data when special message is sent to the window indicating you should exit message loop, close window and appplication is terminated. This equivalent to defineing while loop in main C procedure and when condition of while statement becomes false( equivalent to window receiving close message) you exit while loop and main returns.
