OPENFILENAME示例代码

 OPENFILENAME结构参考MSDN。

HANDLE OpenDataFile(HWND hWnd){　　OPENFILENAME ofn;　　HANDLE hFile;　　char szFileName[MAX_PATH]; 　　strcpy(szFileName, "file.txt");　　memset(&ofn, 0, sizeof(OPENFILENAME));　　ofn.lStructSize = sizeof(OPENFILENAME);　　ofn.hwndOwner = hWnd;　　ofn.lpstrFilter = "Text Files (*.TXT)\0*.txt\0\　　　　　　　　　　 ASCII Files (*.ASC)\0*.asc\0\　　　　　　　　　　 All Files (*.*)\0*.*\0\0";　　ofn.lpstrFile = szFileName;　　ofn.nMaxFile = MAX_PATH;　　ofn.lpstrTitle = "Open File";　　ofn.Flags = OFN_FILEMUSTEXIST | OFN_HIDEREADONLY;　　if(GetOpenFileName(&ofn))　　　　hFile = CreateFile(szFileName, GENERIC_READ, 0, NULL, OPEN_EXISTING, 0, NULL);　　else　　　　MessageBox(0, "Cannot open the file", "Open File", MB_ICONSTOP | MB_OK);　　return hFile;}
