Overriding the minimize, size and close toolbar buttons

[shades234]

hi, i'm new here and have a programming question


I'm developing a SDI program with database use. I want to override the buttons in the top right of the screen, the _, the resize and the (x) close buttons.

what i really want is for the users not to be able to resize the windown in any way, and if they hit [x] to close, it brings up a box asking if they really want to close. i was able to get the File->Close to refer to the close button i made.

can anyone point me in the right direction

Remove them if you don't want them, if you're using Windows forms it's just a setting in the properties tab.... otherwise if you want to do it in code you need to use the SetWindowLong() function and set the style as not WS_MINIMIZEBOX & not WS_MAXIMIZEBOX

As far as the close confirmation just put what you want in the appropriate message handler, WM_DESTROY if I'm not mistaken, but that may be too late I'm not certain.

i tried that, but if the user doubble clicks on the top tool bar even if the min and max buttons aren't there, the program still does a resize and then i can't get the program to maximize

Are you using Windows forms? If so, have you set the resizable flag to false?

Try responding to the WM_SIZE message and not letting the size be smaller than full screen.

For the close, I think you want WM_CLOSE; WM_DESTROY is too late. There's also a message that asks the program if it is in a state where it can close. If necessary I can find it for you.

i reid the close and destroy but they happened after my event.

i found that using the mainfrm.cpp and working with the close in there is fine, but i need to save data from my program, is there a way to access it from mainfrm.cpp? my data is stored in "Connector TestView.cpp" but the class is CConnectorTestView
