Hi I use UniDAC for accessing SQL Server data, though I note there is also SDAC.

I have recently been getting the occasional exception with message: "OLE DB error occurred. Code 80040E21h".

This is difficult to repro so I am trying to get as much information when the error arises.

Internet zen says I should walk the raw OLE DB IErrorInfo/ISQLErrorInfo for further information.

The only evident exception class is DBAccess.EDAError, which doesn't offer much other than the ErrorCode property.

However over in SDAC I see there are EOLEDBError and EMSError exception classes that surface an array of error objects with messages that might potentially provide useful information.

Is there any means to get more information from UniDAC when a vague OLE DB error occurs deep down inside the stack? I really need more information and it seems I do not have it....

Thanks
