刚学到滚动条, 突然想到这小甲鱼的这个例子, 折腾了很久还是加不上滚动条
- #include <Windows.h>
- LRESULT CALLBACK WndProc(HWND, UINT, WPARAM, LPARAM);
- int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, PSTR szCmdLine, int iCmdShow)
- {
- WNDCLASS wndclass;
- static TCHAR* szAppName = TEXT("abc");
- HWND hwnd;
- MSG msg;
- wndclass.style = CS_HREDRAW | CS_VREDRAW;
- wndclass.lpfnWndProc = WndProc;
- wndclass.cbClsExtra = 0;
- wndclass.cbWndExtra = 0;
- wndclass.hInstance = hInstance;
- wndclass.hIcon = LoadIcon(hInstance, IDI_APPLICATION);
- wndclass.hCursor = LoadCursor(NULL, IDC_ARROW);
- wndclass.hbrBackground = (HBRUSH)GetStockObject(WHITE_BRUSH);
- wndclass.lpszMenuName = NULL;
- wndclass.lpszClassName = szAppName;
- if (!RegisterClass(&wndclass))
- {
- MessageBox(NULL, TEXT("程序只能在 Windows NT 下运行"),
- szAppName, MB_ICONERROR);
- return 0;
- }
- hwnd = CreateWindow(szAppName,
- TEXT("abc"),
- WS_OVERLAPPEDWINDOW,
- CW_USEDEFAULT,
- CW_USEDEFAULT,
- 600, 400,
- NULL, NULL,
- hInstance,
- NULL);
- ShowWindow(hwnd, iCmdShow);
- UpdateWindow(hwnd);
- while (GetMessage(&msg, NULL, 0, 0))
- {
- TranslateMessage(&msg);
- DispatchMessage(&msg);
- }
- return msg.wParam;
- }
- LRESULT CALLBACK WndProc(HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam)
- {
- PAINTSTRUCT ps;
- HDC hdc;
- TCHAR szBuffer[128];
- int i;
- switch (message)
- {
- case WM_PAINT:
- hdc = BeginPaint(hwnd, &ps);
- for (i = 0; i < 100; i++)
- {
- wsprintf(szBuffer, TEXT("%d: %s"), i + 1, TEXT("I love FishC.com!"));
- TextOut(hdc, 0, i * 15, szBuffer, lstrlen(szBuffer));
- }
- EndPaint(hwnd, &ps);
- return 0;
- case WM_DESTROY:
- PostQuitMessage(0);
- return 0;
- }
- return DefWindowProc(hwnd, message, wParam, lParam);
