如何给控件定义类对象？？

[klkkklkl]

如题

老大我就怎么多分了全给你了

使用RegisterClassEx

ATOM RegisterClassEx(
CONST WNDCLASSEX *lpwcx // class data
);

以下例子来源于MSDN:

#include <windows.h>

// Global variable

HINSTANCE hinst;

// Function prototypes.

int WINAPI WinMain(HINSTANCE, HINSTANCE, LPSTR, int);
InitApplication(HINSTANCE);
InitInstance(HINSTANCE, int);
LRESULT CALLBACK MainWndProc(HWND, UINT, WPARAM, LPARAM);

// Application entry point.

int WINAPI WinMain(HINSTANCE hinstance, HINSTANCE hPrevInstance,
LPSTR lpCmdLine, int nCmdShow)
{
MSG msg;

if (!InitApplication(hinstance))
return FALSE;

if (!InitInstance(hinstance, nCmdShow))
return FALSE;

while (GetMessage(&msg, (HWND) NULL, 0, 0) != 0 && GetMessage(&msg, (HWND) NULL, 0, 0) != -1)
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
return msg.wParam;
UNREFERENCED_PARAMETER(lpCmdLine);
}

BOOL InitApplication(HINSTANCE hinstance)
{
WNDCLASSEX wcx;

// Fill in the window class structure with parameters
// that describe the main window.

wcx.cbSize = sizeof(wcx); // size of structure
wcx.style = CS_HREDRAW |
CS_VREDRAW; // redraw if size changes
wcx.lpfnWndProc = MainWndProc; // points to window procedure
wcx.cbClsExtra = 0; // no extra class memory
wcx.cbWndExtra = 0; // no extra window memory
wcx.hInstance = hinstance; // handle to instance
wcx.hIcon = LoadIcon(NULL,
IDI_APPLICATION); // predefined app. icon
wcx.hCursor = LoadCursor(NULL,
IDC_ARROW); // predefined arrow
wcx.hbrBackground = GetStockObject(
WHITE_BRUSH); // white background brush
wcx.lpszMenuName = "MainMenu"; // name of menu resource
wcx.lpszClassName = "MainWClass"; // name of window class
wcx.hIconSm = LoadImage(hinstance, // small class icon
MAKEINTRESOURCE(5),
IMAGE_ICON,
GetSystemMetrics(SM_CXSMICON),
GetSystemMetrics(SM_CYSMICON),
LR_DEFAULTCOLOR);

// Register the window class.

return RegisterClassEx(&wcx);
}

BOOL InitInstance(HINSTANCE hinstance, int nCmdShow)
{
HWND hwnd;

// Save the application-instance handle.

hinst = hinstance;

// Create the main window.

hwnd = CreateWindow(
"MainWClass", // name of window class
"Sample", // title-bar string
WS_OVERLAPPEDWINDOW, // top-level window
CW_USEDEFAULT, // default horizontal position
CW_USEDEFAULT, // default vertical position
CW_USEDEFAULT, // default width
CW_USEDEFAULT, // default height
(HWND) NULL, // no owner window
(HMENU) NULL, // use class menu
hinstance, // handle to application instance
(LPVOID) NULL); // no window-creation data

if (!hwnd)
return FALSE;

// Show the window and send a WM_PAINT message to the window
// procedure.

ShowWindow(hwnd, nCmdShow);
UpdateWindow(hwnd);
return TRUE;

}

比如组合框控件
直接定义成这样CComboBox m_myBox;

你的意思是这样吗？

[klkkklkl]

stevecrisewu(月亮骑士) 我的意思就是你说的

[flyelf]

直接这么定义之后，如果该控件还没有创建，那么还需要调用Create方法来创建，或者使用SubclassDlgItem直接依附到某个已经创建的控件上

非常感谢
