问题出在这一行:
改正如下:
- #include <windows.h>
- #include <strsafe.h>
- LRESULT CALLBACK WndProc(HWND, UINT, WPARAM, LPARAM);
- int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, PSTR szCmdLine, int iCmdShow)
- {
- static TCHAR szAppName[] = TEXT("MyWindows");
- HWND hwnd;
- MSG msg;
- WNDCLASS wndclass;
- wndclass.style = CS_HREDRAW | CS_VREDRAW;
- wndclass.lpfnWndProc = WndProc;
- wndclass.cbClsExtra = 0;
- wndclass.cbWndExtra = 0;
- wndclass.hInstance = hInstance;
- wndclass.hIcon = LoadIcon(NULL, 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("这个程序需要在 Windows NT 才能执行!"), szAppName, MB_ICONERROR);
- return 0;
- }
- hwnd = CreateWindow(szAppName,
- TEXT("鱼C工作室"),
- WS_OVERLAPPEDWINDOW | WM_HSCROLL | WM_VSCROLL,
- 200,
- 100,
- 300,
- 200,
- 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)
- {
- HDC hdc;
- PAINTSTRUCT ps;
- RECT rect;
- static TCHAR str[300][200];
- int i, j, t;
- size_t it;
- TEXTMETRIC tm;
- static int cxChar, cyChar, cxCou, cyCou;
- switch (message)
- {
- case WM_SIZE:
- hdc = GetDC(hwnd);
- SelectObject(hdc, GetStockObject(SYSTEM_FIXED_FONT));
- GetTextMetrics(hdc, &tm);
- GetClientRect(hwnd, &rect);
- cxChar = tm.tmAveCharWidth;
- cyChar = tm.tmHeight;
- cxCou = (rect.right - rect.left) / cxChar;
- cyCou = (rect.bottom - rect.top) / cyChar;
- for (i = 0; i < 300; i++)
- {
- StringCchPrintf(&str[i][0], 200, TEXT("%d"), i + 1);
- StringCchLength(&str[i][0], 200, &it);
- for (j = it, t = 0; j < 200; j++, t++)
- {
- if (t > 25) t = 0;
- str[i][j] = 'A' + t;
- }
- }
- ReleaseDC(hwnd, hdc);
- return 0;
- case WM_PAINT:
- hdc = BeginPaint(hwnd, &ps);
- SelectObject(hdc, GetStockObject(SYSTEM_FIXED_FONT));
- for (i = 0; i < cyCou; i++)
- {
- for (j = 0; j < cxCou; j++)
- {
- TextOut(hdc, cxChar*j, cyChar*i, &str[i][j], 1);
- }
- }
- EndPaint(hwnd, &ps);
- return 0;
- case WM_DESTROY:
- PostQuitMessage(0);
- return 0;
- }
- return DefWindowProc(hwnd, message, wParam, lParam);
- }
