BOOL ModifyStyleEx( DWORD dwRemove, DWORD dwAdd, UINT nFlags = 0 );[通俗易懂]

大家好，又见面了，我是你们的朋友全栈君。

CWnd::ModifyStyleEx //修改窗口的Style

BOOL ModifyStyleEx( DWORD dwRemove, DWORD dwAdd, UINT nFlags = 0 );

Return Value

Nonzero if style was successfully modified; otherwise, 0.

Parameters

dwRemove

Specifies extended styles to be removed during style modification.

dwAdd

Specifies extended styles to be added during style modification.

nFlags

Flags to be passed to SetWindowPos, or zero if SetWindowPos should not be called. The default is zero. See the Remarks section for a list of preset flags.

Remarks

Call this member function to modify a window’s extended style. Styles to be added or removed can be combined by using the bitwise OR (|) operator. See the topics Extended Window Styles in this book and::CreateWindowEx in the Win32 SDK Programmer’s Reference for information about the available extended styles

If nFlags is nonzero, ModifyStyleEx calls the Windows API function::SetWindowPos and redraws the window by combining nFlags with the following four preset flags:

• SWP_NOSIZE Retains the current size.
• SWP_NOMOVE Retains the current position.
• SWP_NOZORDER Retains the current Z order.
• SWP_NOACTIVATE Does not activate the window.
