//按钮点击
DL = FindWindowEx(h, DL, "AfxWnd42", null);
if (!DL.Equals(IntPtr.Zero))
{
SendMessage(DL, WM_CLICK, h, "0");
}
}
}
为什么这个点击没有执行呢？？

//按钮点击 //DL = FindWindowEx(h, DL, "AfxWnd42", null); DL = FindWindowEx(h, YZMA, "AfxWnd42", null); 或者 DL = FindWindowEx(h, MIMA, "AfxWnd42", null);

如果真的找到了按钮的指针，完全可以用API找到按钮的区域，然后用API把光标挪到那个区域然后模似一个左键单击。
[解决办法]
BM_CLICK是"BUTTON"类的消息，不知道这个"AfxWnd42"类是否响应这个消息。
BM_CLICK消息要求后两个参数都是0，并且按钮所在窗口必须处于激活状态才会响应。
可以试试向父窗口发BN_CLICKED事件（通过WM_COMMAND消息）；或者向按钮Post鼠标消息。
