Replacing WinMain() with main() function in Win32 programs

Question

I searched a little bit on StackOverflow and Google but couldn't get the idea. I want to start my application with this type of user programming:

int main() {   Window App("Test", 640, 480);    while(App.IsOpen())   {     // Do the stuff   } } 

But this isn't possible because I should pass the hInstance and hPrevInstance and other parameters to a WinMain function. Actually there is a Window class which I designed to make the window creation a little bit easier. I saw this implementation on SFML but I don't know how it did come to this.

Right now I'm using the usual way:

int WINAPI WinMain(HINSTANCE hInst, HINSTANCE hPrevInst, LPSTR, int) {   Window App(hInst, hPrevInst, "Test", 640, 480);    while(App.IsOpen())   {     // Do the stuff   } } 

Thanks.

You can use standard main in a "windows" app (that is, a GUI subsystem Windows application) even with the Microsoft tools, if you add the following to the Microsoft linker options:

/subsystem:windows /ENTRY:mainCRTStartup 

Note that this is not necessary for the GNU toolchain.

Still for the Microsoft tools you can alternatively add this to your main file:

#ifdef _MSC_VER #    pragma comment(linker, "/subsystem:windows /ENTRY:mainCRTStartup") #endif 

James McNellis tells you how to get the hInstance.
