    Combobox .change event stops work after a while??

    Hi
    I am building a large application where we use the combobox feature a
    lot.
    Its an office addin for office XP.
    I am using Visual studio 2003 VB.

    In outlook and excel it works perfect all the time, but in Word it
    stops work after a randomly amount of time?
    (The Event ".Change" does apparently not fire).
    Does anyone have some ideas what can cause this problem?

    Below are some code snippets from my application.
    Any help appriciated.

    Kind Regards:
    Karsten Markmann

    cbrNewToolbar = KiCData.hostApp .CommandBars.Ad d(Name:="KiC LRØ

    With cmbSearchCoveo

      Difficult to tell, but it looks like you didn't declare the object
      variable for the toolbars and buttons at the class level? If you do
      not, they'll eventually be garbage collected.

      The other thing to watch out for is that you should assign a unique
      string value to the controls' TAG property. Word uses this (with its
      MDI UI) to keep track of what window you're currently in.

              Karsten,

              I an not (yet) known with using Microsoft.offic e in VB.Net.

              However be aware that an event in a combobox in VB.Net will often result
              that he calls himself again (recursive) a good reason that your program
              stops because the combobox has eaten all your memory.

              Cor
