Thread: Windows GUI

How does C code become windows program ? do you design your app windows in Visual studio and paste code on buttons sort of like creating hyperlinks and hotspots on a web page ?

just curious

thanx..

For dialog style applications, pretty much.

I am not sure I understand your question quite well but perhaps this might help

Code:

#include <windows.h> 

LRESULT CALLBACK WindowFunc(HWND, UINT, WPARAM, LPARAM); 
char szWinName[] = "MyWin"; 

int WINAPI WinMain(HINSTANCE hThisInst, HINSTANCE hPrevInst, 
LPSTR lpszArgs, int nWinMode) 
{ 
        HWND hwnd; 
        MSG msg; 
        WNDCLASSEX wcl; 

        wcl.cbSize = sizeof(WNDCLASSEX); 

        wcl.hInstance = hThisInst; 
        wcl.lpszClassName = szWinName; 
        wcl.lpfnWndProc = WindowFunc; 
        wcl.style = 0; 

        wcl.hIcon = LoadIcon(NULL, IDI_APPLICATION); 
        wcl.hIconSm = NULL; 
        wcl.hCursor = LoadCursor(NULL, IDC_ARROW); 

        wcl.lpszMenuName = NULL; 
        wcl.cbClsExtra = 0; 
        wcl.cbWndExtra = 0; 

        if(!RegisterClassEx(&wcl)) return 0; 

        hwnd = CreateWindow(

        while(GetMessage(&msg, NULL, 0, 0))
