Question

When I build and run code, the window opens and closes instantly

Anonymous

The program '[8796] PLEASE.exe' has exited with code 184 (0xb8).

How to get the window to stay open? Even a hello world program window doesnt stay open.

Do what RLWA32 said,

and, as I see "game" in your code, a game loop is rather with PeekMessage instead of GetMessage...

Answer 1

The program you are running is incomplete. It is missing a message loop so it exits immediately. Because it does not return an int value upon exit the error code that is printed is not meaningful. These are not the only issues with the code that is shown by the attached image.

You should create a new project using the Windows Desktop Application template as shown below -

This will create a fully formed Windows desktop application that you can study and/or modify to meet your needs.
