Select-Event - Strange Behavior

[C-Hoppen]

Hello!

I've been watching for a long time a strange behavior I can not explain.

• I have a Add-In that starts a Win-Form. This form contains a button.
• When the user clicks the button, a selection is started (Select-Event as shown in the API-Sample).
• I always use the same code to handle the Select Event.
• The form is a child of Inventor [IntPtr _temp = SetWindowLong(this.Handle, GWL_HWNDPARENT, oApp.MainFrameHWND);]

After starting the Select Event objects should be prehighlighted when the mouse moves over.

Sometimes it does, sometimes I first have to click in the inventor window to see prehighlighting.

It seems to be an arbitrary behavior.

Is this a known issue?

Hi,

Try setting the parent like this instead:

That might not solve the issue though, which sounds like the focus stays on your dialog. You could simply try to activate the Inventor main window before starting the selection.

Cheers,
