My MDI form has several child forms in maximized state. Pressing Ctrl-F6
causes next child to show, which I don't like. How can I cancel standard
Ctrl-F6 behaviour?
Thank you

Alex,
You should be able to hook into the KeyDown event on the main form, and
detect the modifier that is pressed at the same time (the ctrl key). You
should be able to cancel this event.
If that doesn't work, then you can always override the WndProc method on
the main form and then handle the key events there (by handling the windows
message yourself).
Hope this helps.

See Nicholas' earlier post on some options to do what you want.
However, you might like to consider that, unless you are writing
applications *only for yourself*, what you like and dislike is largely
irrelevant. Ctrl-F6 is the standard keystroke for moving between child forms
in MDI apps (as you know), so any of your users who've ever used such an app
(e.g. Word, Excel etc) will fully expect to be able to use that keystroke in
your app too, otherwise they might move to another vendor's solution whose
usage is more intuitive to them.
Just a thought...
KeyDown on main form does not work: it is not fired when ctrl-F6 pressed.
Now I am trying to catch it in WndProc
Thanks

I wrote "I don't like" just to indicate my problem. For my application it is
absolutely critical to avoid standard MDI behaviour because it appears to
user as a normal single form interface. (only one child is visible at any
particular moment and MDI parent controls the switching between childs based
on functions executed by user).
So don't worry about me losing clients: the app is developed by their specs.
BTW, from options suggested by Nicholas, none seem to work. So, I am still
looking for the right answer...

Alex,
What messages are you looking for in WndProc? There has to be SOME
message that is handling this, you just have to find the right one.
Also, are you calling the base implementation before or after you check
the message in WndProc?

I've found the solution.
Message is WM_SYSCOMMAND = 0x112,
and WndProc must be defined in all child forms, but not in MDI paremt form.
Finally, it works!
Thank you

I'm creating a simple reply form, and if a form item isn't answered I
get an error:
"Notice: Undefined index: rb_amntspent in

even if in the code I allow for an unselected item. (Code at the

It works fine otherwise.
Now in the past I've made a change to php.ini to repress errors, but
for this project I don't have access to the php.ini.

Hi all,
I have a simple aspx page. On the page there is only one button. When I
click on the button, the event sequence is Page_Load, Button1_click and
Page_PreRender. How do I supress the PreRender event? I know if I call
Server.Transfer or Reponse.Redirect in the Button1 click event, the page
prerender event will not occur.
Thanks.
