ComboBox errors part 3
Accessing ComboBox.ListCount on disabled combobox throws

An unspecified COM exception is thrown when accessing a ComboBox where Enabled == false.

The exception is (Exception from HRESULT: 0x80004005 (E_FAIL))

Is this a known issue, and is there a fix or work around ?

Stig, you get the exception because the combo box is not connected to the Office control. Can you please send me the code? I will test it on my PC.

This happens in my code as well. It's easy enough to recreate. If you set your combobox to Enabled=false all of you properties have COM exceptions in the watch window. Set Enabled=true everything works again. The information is always there in the base.

Hi Will.

For some reason MS Office Object Model doesn't allow us to access control's properties if it is disabled.
