Stop window from being able to maximize

Hey, I have a program with a dialog and i want it not to be able to maximize. With the ms visual c++ resource editor I seleced it not to have the maximize button in the top right corner. However you can still click on the window on the taskbar and choose maximize. How can i stop this?

I have a dialog and in the "Dialog Properties" under the "Styles" tab, I have "Title Bar", "System menu" & "Minimize box" checked and that disallows the dialog to be maximized even from the taskbar. I don't know if this is any help but I thought i'd say anyway. :)

Yah, i have the same things selected, however you can maximize it from the taskbar.

This is easy to do. When you create the window make sure that the third argument for the CreateWindow() doesn't OR in WS_MAXIMIZE, WS_OVERLAPPEDWINDOW, or WS_TILEDWINDOW. Now the window will be created without a maximize button (even on the task bar).

I'm not using CreateWindow though. I'm making a dialog in visual c++ 6 and then calling it with DialogBox().

Opps must read the other posts.


If you create the dialog in VC then just deselect the 'maximise box' or 'system menu' under STYLES (2nd TAB) in the resource editor.

else
Get the dlg's style with GetWindowLong() and GWL_STYLE and '~' off the WS_MAXIMIZEBOX style.
Then put the style back with SetWindowLong().

Yes, that exactly what I'm doing with VC.

"and '~' off the WS_MAXIMIZEBOX style." How do you do this?

Try this:

-----
ModifyStyle(WS_MAXIMIZEBOX, 0, 0)

or

GetParent()->ModifyStyle(WS_MAXIMIZEBOX, 0, 0)

I'm not using mfc so those commands don't work.

DWORD foo=(DWORD) GetWindowLong(hwnd, GWL_STYLE);
SetWindowLong(hwnd, GWL_STYLE, (LONG) (foo & (~WS_MAXIMIZE)));

P.S. Replace hwnd with the handle of your window.
