Disable Window Resizing Win32
提问by Chris
how do I disable resizing by dragging the edge of windows?
如何通过拖动窗口边缘禁用调整大小？

The WS_OVERLAPPEDWINDOWstyle includes the WS_THICKFRAMEstyle which, i think, is responslible for making your window resizeable.
该WS_OVERLAPPEDWINDOW款式包括WS_THICKFRAME风格，我想，是responslible为使您的窗口调整大小。
Consider something like
考虑类似
dwStyle=(WS_OVERLAPPED | WS_CAPTION | WS_SYSMENU | WS_MINIMIZEBOX | WS_MAXIMIZEBOX);
回答by user3006930
You can use WS_OVERLAPPEDWINDOW ^ WS_THICKFRAME
您可以使用 WS_OVERLAPPEDWINDOW ^ WS_THICKFRAME
The XOR will keep everything in WS_OVERLAPPEDWINDOW except for WS_THICKFRAME
XOR 会将所有内容保留在 WS_OVERLAPPEDWINDOW 中，除了 WS_THICKFRAME
回答by Jingjing Zhong
You can try something like this:
你可以尝试这样的事情：
::SetWindowLong(hWnd, GWL_STYLE, GetWindowLong(hWnd, GWL_STYLE)&~WS_SIZEBOX);
It only disable resizing by dragging the edge of windows. By the way, WS_SIZEBOX is the same as WS_THICKFRAME because of
它只能通过拖动窗口边缘来禁用调整大小。顺便说一下，WS_SIZEBOX 和 WS_THICKFRAME 是一样的，因为
#define WS_SIZEBOX WS_THICKFRAME
回答by ciyo
If you use WS_OVERLAPPED | WS_MINIMIZEBOX | WS_SYSMENU, it disable both maximizing and resizing.
如果您使用WS_OVERLAPPED | WS_MINIMIZEBOX | WS_SYSMENU，它将禁用最大化和调整大小。
回答by Ben Dove
Change your window style from WS_OVERLAPPEDWINDOW to, say, WS_CAPTION | WS_SYSMENU | WS_MINIMIZEBOX. In other words, it's overlappedwindow minus the thickframe (resizable border) and the maxbox.
将窗口样式从 WS_OVERLAPPEDWINDOW 更改为 WS_CAPTION | WS_SYSMENU | WS_MINIMIZEBOX。换句话说，它是重叠窗口减去厚框（可调整大小的边框）和最大框。

Process the WM_SIZING message and override all attempts to change the window's rectangle.
处理 WM_SIZE 消息并覆盖所有更改窗口矩形的尝试。

That works for me, but instead of using
这对我有用，但不是使用
WS_OVERLAPPEDWINDOW & ~WS_THICKFRAME
use only
只使用
WS_OVERLAPPEDWINDOW
