Code:
#include "stdafx.h"
#include <windows.h>
#include "Dx.h"
HWND g_hwnd;
INT WINAPI WinMain(HINSTANCE hInstance,HINSTANCE,LPSTR,INT)
{
RegisterWindowClass(hInstance);
RegisterWindow(hInstance);
ShowWindow(g_hwnd,SW_SHOWDEFAULT);
UpdateWindow(g_hwnd);
INT result = StartMessageLoop();
return result;
}
LRESULT WINAPI WndProc(HWND hWnd,UINT msg,WPARAM wParam,LPARAM lParam)
{
switch(msg)
{
case WM_CREATE:
return 0;
case WM_DESTROY:
PostQuitMessage(0);
return 0;
case WM_PAINT:
ValidateRect(g_hwnd,NULL);
return 0;
}
return DefWindowProc(hWnd,msg,wParam,lParam);
}
void RegisterWindowClass(HINSTANCE hInstance)
{
WNDCLASSEX wc;
wc.cbSize = sizeof(WNDCLASSEX);
wc.style = CS_HREDRAW | CS_VREDRAW | CS_OWNDC;
wc.lpfnWndProc = WndProc;
wc.cbClsExtra = 0;
wc.cbWndExtra = 0;
wc.hInstance = hInstance;
wc.hIcon = LoadIcon(NULL,IDI_APPLICATION);
wc.hCursor = (HCURSOR)LoadCursor(hInstance,IDC_ARROW);
wc.hbrBackground = (HBRUSH)GetStockObject(WHITE_BRUSH);
wc.lpszMenuName = NULL;
wc.lpszClassName = "WinApp";
wc.hIconSm = NULL;
RegisterClassEx(&wc);
}
void RegisterWindow(HINSTANCE hInstance)
{
g_hwnd = CreateWindowEx(NULL,"WinApp","Basic Windows Application",
WS_OVERLAPPEDWINDOW,
100,
