Problem with key events in dockable windows

[thomas.klaus]

Hi there,

We use dockable windows to show own forms and controls. Now we have a
problem with several key presses. For example, a textbox has the focus
within a dockable window, now when the user presses the Delete key,
the selected shape will be removed from the Visio drawing, when I only
want to delete a character in the textbox! How can I avoid that the
Keyevent gets through to Visio? I can catch the KeyUp event in the
textbox and can handle the Delete, but I don't know how to avoid that
this key gets through to Visio...

The strange thing is in a Combobox it works! That means the delete
keys removes one char without deleting the selected shape.

Many thanks in advance.
Tom

Hi Tom,

It's bedtime here in Vienna, so I don't have more time to look into
this, but you might search the Visio Developer Help for:

OnKeystrokeMessageForAddon

I think this has something to do with what you need.

Chris,

Thanks for your reply.

I have a C# Visio COM-AddIn and i'm trying to catch the
OnKeystrokeMessageForAddon event. But unfortunetaly an event is never
caught.

Here is the C# code for a dockable window:
Window visioWindow = visibleVisioDocument.Window.Windows.Add(
findElementForm.Text,
tagVisWindowStates.visWSAnchorLeft |
tagVisWindowStates.visWSAnchorAutoHide |
tagVisWindowStates.visWSVisible,
tagVisWinTypes.visAnchorBarAddon,
0, top, width, height, null, null, null);
visioWindow.OnKeystrokeMessageForAddon +=
visioWindow_OnKeystrokeMessageForAddon;

Thanks for your help.
Tom

You should try declaring your visioWindow object globally rather than
locally. Otherwise it will go out of scope and the event handler will be
terminated.

Hi Mark,

Thanks for your answer. I tried to set the visioWindow and the event
handler object globally. I even tried to catch the event on the
application, but without success. You got any hints for that?

Thanks!

Regards,
Tom

Take a look at the event stream from Visio using the EventMonitor tool (part
of Visio's SDK) to make sure that the event is firing.

Mark, the event OnKeystrokeMessageForAddon is not even listed in the
event options of the EventMonitor tool of Visio 2007!

Hmm, quite right. I need to investigate that further.
