Why is an MSCOMM control in my Access application no longer supported by my application?
Posted on 2009-07-09
I am developing an Access 2007 "project" (.adp) as a front end to a SQL Server 2005 Express database.
A couple of months ago I got myself sorted with "MSCOMM32.OCX" that allowed me to add a "Microsoft Communications Control V6" Active X Control to an Access Form, which in turn allowed me to read input from a barcode scanner attached to the COM1 serial port.
That all worked OK, but now that I am returning to do final testing, it seems that the control is not working.
I get a run-time error when I try to open the Form that contains the control and initialise its settings (error # 438, "Object doesn't support this object or method").
When I look at the form in "design mode", the control appears as a plain white box, as opposed to the "telephone icon" that I think appeared previously.
When I try to add a new MSCOMM control to my form I am told that my project "doesn't support this ActiveX control".
In my VBA Editor's "Tools - References" list, the "Microsoft Comm Control 6.0" box is ticked.
Can anyone explain why this control appears to have become disabled and how I can make it active again?
