如何判断窗口标题栏是否具有最大化，最小化，关闭按钮？

如题！

[zwfgdlc]

if (GetWindowLongPtr(hwnd, GWL_STYLE) & WS_MAXIMIZEBOX) //有最大化按钮
if (GetWindowLongPtr(hwnd, GWL_STYLE) & WS_MINIMIZEBOX) //有最小化按钮

[Eleven]

GetWindowLong(...,GWL_STYLE,...);

The GetWindowLongPtr function retrieves information about the specified window. The function also retrieves the value at a specified offset into the extra window memory.

If you are retrieving a pointer or a handle, this function supersedes the GetWindowLong function. (Pointers and handles are 32 bits on 32-bit Microsoft Windows and 64 bits on 64-bit Windows.) To write code that is compatible with both 32-bit and 64-bit versions of Windows, use GetWindowLongPtr.
