[펌] 콘솔 어플리케이션에서 윈도우 만들기

[펌자료] 원문 : http://unfinished.egloos.com/3138081

C의 console application mode에서 윈도우를 만들기.

가장 핵심이 되는 것은 system에서 받아와야 옳지만, console application에서는 자동으로 받을 수 없는 WNDCLASS 구조의hInstance였다.

 HINSTANCE hInstance = GetModuleHandle(NULL);

아래의 코드를 실행하면 이렇게 간단한 윈도우가 생성된다.

#include <windows.h>

LRESULT CALLBACK WndProc(HWND hWnd, UINT iMessage, WPARAM wParam, LPARAM IParam);
HINSTANCE g_Inst;
LPCTSTR lpszClass = TEXT("First");

int main()
{
 HWND hWnd;
 MSG Message;
 WNDCLASS WndClass;

 HINSTANCE hInstance = GetModuleHandle(NULL);
 g_Inst = hInstance;

 WndClass.cbClsExtra = 0;
 WndClass.cbWndExtra = 0;
 WndClass.hbrBackground = (HBRUSH)GetStockObject(WHITE_BRUSH);
 WndClass.hCursor = LoadCursor(NULL, IDC_ARROW);
 WndClass.hIcon = LoadIcon(NULL, IDI_APPLICATION);
 WndClass.hInstance = hInstance;
 WndClass.lpszClassName = lpszClass;
 WndClass.lpszMenuName = NULL;
 WndClass.style = CS_HREDRAW|CS_VREDRAW;

 WndClass.lpfnWndProc = WndProc;

 RegisterClass(&WndClass);

 hWnd = CreateWindow(lpszClass, lpszClass, WS_OVERLAPPEDWINDOW,
      0, 0, 640, 480,
      NULL, (HMENU)NULL, hInstance, NULL);

 ShowWindow(hWnd, SW_SHOW);

 while(GetMessage(&Message, NULL, 0, 0))
 {
  TranslateMessage(&Message);
  DispatchMessage(&Message);
 }

 return (int)Message.wParam;

}
 
LRESULT CALLBACK WndProc(HWND hWnd, UINT iMessage, WPARAM wParam, LPARAM IParam)
{
 switch(iMessage)
 {
 case WM_DESTROY:
  PostQuitMessage(0);
  return 0;
 }

 return(DefWindowProc(hWnd, iMessage, wParam, IParam));
}
