Processing KeyDown in MDI ParentIs there a way to catch a KeyDown event in a MDI parent form? I have a
special admin login prompt that only appears when you press Ctrl+Shift+A, but currently I have to open one of the children forms first before I can catch this key stroke. I do not want this option to be obvious to the end users since I hard-coded that password since I know of no secure way to store it otherwise and not have it get changed from one workstation to another. Thanks. -- Chris Lieb UPS CACH, Hodgekins, IL Tech Support Group - Systems/Apps When a key is pressed, as long as the Alt key is not being pressed, the
WM_KEYDOWN message will be sent to the window that has the focus. When there are no children, this might be the MDI client window, or it may be another window in your application, e.g. a sibling of the MDI client window. Use Spy++ to spy on the main (top level) window of your application, check 'windows of same process' and clear all messages but WM_KEYDOWN, then do your keystroke - then in the message log right click on the message to find out which window it got sent to. I'm not sure whether the MDI client window even can receive focus but if it can and does, then you might have to subclass it to receive the message. If the MDI client window has siblings (e.g. treeview), then you can't be sure it won't be one of the siblings that receives the keystroke message.
