Re: AutomatedQA TestComplete - Interface not supported
Does the object returned by the ColumnByIndex property implement the IDispatch interface?
Also, please set a breakpoint on the problematic line and launch the script. When the script execution is paused on the breakpoint, select 'objectsomthing.ColumnByIndex(2)' in the code editor and press Ctrl + F7 (or click the 'Call the Evaluation Dialog' toolbar button). In the dialog that appears, click Inspect and post here an image of the Inspect window's Properties page.
