Hi, I have several error when I try to change or use the button state of toolbar button in outlook.

For example:

If myADXModule.toolTrack.State = AddinExpress.VSTO.ADXMsoButtonState.adxMsoButtonDown Then

I ot this error (not at each time): COM object that has been separated from its underlying RCW cannot be used.

Another error like this:
append on this code:

toolRegarding.Caption = "Regarding: " & sTexte
toolRegarding.TooltipText = Reponse(1)

RaceOnRCWCleanup was detected
Message: An attempt has been made to free an RCW that is in use. The RCW is in use on the active thread or another thread. Attempting to free an in-use RCW can cause corruption or data loss.

the 2 case are located in the OutlookItemEventsClass and ADXModule class.
How Can I do to resolve this? Thanks

Hi Pierre.

Most likely the button is not connected.
Is the button placed in Outlook inspector?

Yes in the inspector. If I add breakpoint in my code the error are not called out anymore. But without breakpoint, I got the error sometime, I can't found a stable patturn

Hi Pierre.

The point is that you can change the state of inspector controls in the active inspector only. E.g. you can use the code above in the InspectorActivate event handler.

Can I read the state without error or the same problem may appears?

Hi Pierre.

No. You can change/read the state where you want but the changes will apply if at least one inspector is opened. Please check the IsConnected property of the button before you call the State property.

hi,
I try to put on a if bloc the code that generate the problem:

If toolRegarding.IsConnected = True Then
'toolRegarding.Caption = "Regarding: " & sTexte
'toolRegarding.TooltipText = Reponse(1)
End If

But if I do not put the 2 inner line in comment, i got the problem after several test. But in comment all work good. I have a active inspector displyed on the screen. I do:
1- Open the inspector
2- Click on the button ToolRegarding
3- This fonction call a dialog windows asking to select something
4- Close the dialog et return the selection
5- Put the selection name in the captin of the button

The wierd thing is that work well sometime and crash other time.
