at _Click(Object sender, EventArgs e) at (DoWorkEventArgs e) at (Object argument) This operation failed because the QueryInterface call on the COM component for the interface with IID '' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)). System.InvalidCastException: Unable to cast COM object of type '' to interface type ''. It throws following Unhandled exception as soon as i press Detect Media Button. If you can look into the problem that will really be helpful. if you can please try this application on XP, because though it is working on Vista it is not working on XP so many developers are not able to use it in there applications. As i read on blog i saw it is giving problem on xp to many developers. We have tried same application on vista that is working fine.but it is giving following problem on XP SP3. Thanks, for replaying so quickly.Your application regarding IMAPI 2.0 is very useful to many developers.Thanks for that also.
