推荐答案

使用 SetWindowLong [ ^ ] ...

来自互联网:
删除一些样式 [

Use GetWindowLong[^] and SetWindowLong[^]...

From the Internet:
Removing some styles[^]:

LONG lStyle = GetWindowLong(hwnd, GWL_STYLE);
lStyle &= ~(WS_CAPTION | WS_THICKFRAME | WS_MINIMIZE | WS_MAXIMIZE | WS_SYSMENU);
SetWindowLong(hwnd, GWL_STYLE, lStyle);

删除扩展样式 [

Removing extended styles[^]:

LONG lExStyle = GetWindowLong(hwnd, GWL_EXSTYLE);
lExStyle &= ~(WS_EX_DLGMODALFRAME | WS_EX_CLIENTEDGE | WS_EX_STATICEDGE);SetWindowLong(hwnd, GWL_EXSTYLE, lExStyle);

之后，您需要重新绘制窗口:

And after that you need to redraw the window:

SetWindowPos(hwnd, NULL, 0,0,0,0, SWP_FRAMECHANGED | SWP_NOMOVE | SWP_NOSIZE | SWP_NOZORDER | SWP_NOOWNERZORDER);
