任何人都可以告訴我如何使用DropDownList(如C#組合框控件DropDownStyle = DropDownList)創建一個ComboBox沒有資源和沒有MFC?我搜索了大約20分鐘,但是我發現的所有代碼樣本都爲我創建了奇怪的控件(例如,帶有複選框的平原區域,無法檢查...)。我的代碼如下所示:WinApi - >如何創建一個組合框(沒有資源)
WNDCLASSEX wcex;
HWND hwnd;
HWND button;
HDC hDC;
HGLRC hRC;
MSG msg;
BOOL bQuit = FALSE;
float theta = 0.0f;
/* register window class */
wcex.cbSize = sizeof(WNDCLASSEX);
wcex.style = CS_OWNDC;
wcex.lpfnWndProc = WindowProc;
wcex.cbClsExtra = 0;
wcex.cbWndExtra = 0;
wcex.hInstance = hInstance;
wcex.hIcon = LoadIcon(NULL, IDI_APPLICATION);
wcex.hCursor = LoadCursor(NULL, IDC_ARROW);
wcex.hbrBackground = (HBRUSH)GetStockObject(BLACK_BRUSH);
wcex.lpszMenuName = NULL;
wcex.lpszClassName = "GLSample";
wcex.hIconSm = LoadIcon(NULL, IDI_APPLICATION);;
if (!RegisterClassEx(&wcex))
return 0;
/* create main window */
hwnd = CreateWindowEx(0,
"GLSample",
"OpenGL Sample",
WS_OVERLAPPEDWINDOW,
CW_USEDEFAULT,
CW_USEDEFAULT,
256,
256,
NULL,
NULL,
hInstance,
NULL);
ShowWindow(hwnd, nCmdShow);
button = CreateWindow("GLSample", "knopf", WS_CHILD | WS_VISIBLE, 200, 200, 150, 60, hwnd, NULL, hInstance, NULL);
@BlackBear:再次感謝,也許你能告訴我如何獲得當前選定的項目嗎?那麼今天我很高興^^ – 2011-04-13 12:33:16
@Alex Kruger:WM_SETTEXT和WM_GETTEXT應該讓你設置/獲取選擇的項目文本我認爲(從來沒有使用過:)) – BlackBear 2011-04-13 12:41:16
