有点难，害我忙了一星期

[srg777]

我获取了窗口句柄：

POINT pt;
GetCursorPos(&ps);
HWND =WindowFromPoint(pt);

可是怎样判断 hwnd 是可以接受文字输入的窗口？

[dongfa]

得窗口区域，使用GetCaretPos得位置，判断位置不否在区域里.
除此之外，我想还应该调用GetClassName来判断类名是否是"Edit"，若是再判断是否有ES_READONLY属性。
我也是想的，不只能否实现.呵呵~~~`

[不解]

GetWindowStyle..

[srg777]

不在同一个进程中，GetCaretPos 不管用，

输入类名除了Edit外，还有许多，不好判断啊！

[ma811]

用IsKindOf试一试吧
好像用GetWindowLong

[dash]

类名：
vc:Edit; cb or delphi:TEdit; vb:待查

[show]

GetWindowStyle是哪个库里面的，怎么MSDN上没有查到啊？
