The Number property returns a long integer that contains the error code returned by a COM component. This is a standard COM error code.

When decyphering a COM error code, convert the number to hexidecimal, examine the last 8 digits, and use the instructions at Structure of COM Error Codes to understand what the error is. For example, the error -2146828277 converts to FFFFFFFF800A000B in hexidecimal. The 8 represents ?FACULTY_WINDOWS: Used for additional error codes from Microsoft-defined interfaces?, the A represents Visual Basic, and the B represents decimal 11 which is the Visual Basic error code for a "divide by zero" error. For a list of COM error codes, see System Error Codes.
