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;
}
case WM_CREATE:
{
/* The window is being created. Create our button
* window now. */
TEXTMETRIC tm;
/* First we use the system fixed font size to choose
* a nice button size. */
hdc = GetDC (hwnd);
SelectObject (hdc, GetStockObject (SYSTEM_FIXED_FONT));
GetTextMetrics (hdc, &tm);
cx = tm.tmAveCharWidth * 30;
cy = (tm.tmHeight + tm.tmExternalLeading) * 2;
ReleaseDC (hwnd, hdc);
/* Now create the button */
hwndButton = CreateWindow (
"button ",/* Builtin button class */
"Click Here ",
