Combobox .change event stops work after a while??

Karsten_Markmann

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

Private WithEvents cmbSearchCoveo As CommandBarComboBox
----

cbrNewToolbar = KiCData.hostApp.CommandBars.Add(Name:="KiC LRØ
system 2", Position:=msoBarTop, Temporary:=True)
----

cmbSearchCoveo =
cbrNewToolbar.Controls.Add(Type:=MsoControlType.msoControlComboBox)
With cmbSearchCoveo
.BeginGroup = True
.Visible = True
.Style = MsoComboStyle.msoComboLabel
.Caption = "Fritekst søgning:"
.TooltipText = "Fritekst søgefelt i KiC systemet.
Søger i alle dokumenter efter det skrevne."
.Tag = "SearchCoveo"
End With

Private Sub cmbSearchCoveo_Change(ByVal Ctrl As
Microsoft.Office.Core.CommandBarComboBox) Handles
cmbSearchCoveo.Change

ShowIEURL(HTTPSEARCH & cmbSearchCoveo.Text)

End Sub

Click to expand...
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.office 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.
