win32程序响应创建的按钮(用API写的).
代码如下：
创建了一个按钮，并且成功显示，但我要响应这个按钮，我就无从下手了，
记得MFC都有 ID 什么的，现在这个ID不晓得怎么下手啊，
求指点~~~~~~
HWND CreateButton()
{
HWND hwndButton;
hwndButton = CreateWindowEx(WS_EX_WINDOWEDGE ,//附加样式
WC_BUTTON ,//窗口类
"BUTTON",// 窗口的标题
// 窗口样式 ：可见，子窗口，
WS_CHILDWINDOW|BS_DEFPUSHBUTTON,
80,
260,
80,
30,
mainhwnd,// 父窗口句柄
(HMENU)NULL,// 没有菜单
mhInstance,// 应用程序实例
NULL );// 没有附加
ShowWindow(hwndButton, SW_SHOWNORMAL); //显示
return hwndButton;
}
[解决办法]
HMENU hMenu, // handle to menu or child-window identifier

case WM_COMMAND 请察看这个消息! 你需要捕捉它，下面的代码对你有作用。
#include <windows.h>
LRESULT CALLBACK WindowProcedure(HWND,UINT,WPARAM,LPARAM);
char szClassName[]= "Filepool ";
int WINAPI WinMain(HINSTANCE hThisInstance,HINSTANCE hPrevInstance,LPSTR lpszArgument,int nFunsterStil)
{
HWND hwnd;
MSG messages;

wincl.hInstance=hThisInstance;
wincl.lpszClassName=szClassName;

}

ShowWindow(hwnd,nFunsterStil);
while(GetMessage(&messages,NULL,0,0))
{
TranslateMessage(&messages);
DispatchMessage(&messages);
}
return messages.wParam;

SelectObject (hdc, GetStockObject (SYSTEM_FIXED_FONT));

ReleaseDC (hwnd, hdc);
/* Now create the button */
hwndButton = CreateWindow (

CreateWindow的参数HMENU

HWND hButton = NULL;
#define IDC_BUTTON 0x1101
case WM_CREATE:
{
hButton = CreateWindow(_T("BUTTON"), _T("Button"), WS_CHILD

WS_VISIBLE

BS_PUSHBUTTON,
0, 0, 100, 30, hWnd, (HMENU)IDC_BUTTON, hInst, NULL);
}
break;
case WM_COMMAND:
wmId = LOWORD(wParam);
wmEvent = HIWORD(wParam);
// Parse the menu selections:
switch (wmId)

case IDC_BUTTON:
MessageBox(hWnd, _T("Hello,World!"), _T("Message"), MB_OK

MB_ICONINFORMATION);
break;
default:
return DefWindowProc(hWnd, message, wParam, lParam);
}
break;

hMenu就是控件ID
