在得到一个按钮句柄的情况下,如何用使用SENDMESSAGE中的VM_ENABLE使得该按钮变得可用和可见呢?

SendMessage(YourHandleThatYouWantToSetItEnabled, VM_ENABLE, Longint(True), 0);
or
SendMessage(YourHandleThatYouWantToSetItEnabled, VM_ENABLE, Longint(False), 0);

So easy!

其实还有单独的API的
EnableWindow
这个可以单独用。

EnableWindow(button2.Handle, True);
showwindow(button2.Handle,longint(True));
谢谢了！
