Home : Search : Code Sample Library : Downloads : About : Feedback : Because CDO 1.x and the CDO HTML Rendering library 1.x relies on MAPI all calls return a value which is zero if the call was successful or non-zero if an error, or warning, has occurred. A warning means the call was at least partially successful but may have produced an unexpected result or side effect. An error means the call was not successful.
For Microsoft Visual Basic programmers CDO 1.x define 32-bit type library constants for all relevant warning and error codes. They are returned as 32-bit values to Microsoft Visual Basic programs for both warnings and errors, but Microsoft Visual Basic treats the two cases differently. Errors are passed as 32-bit codes, while warnings are returned as the sum of decimal 1000 and the low-order word of the warning, even on a 32-bit platform.
To test for a warning in a Microsoft Visual Basic program, it is possible to use the decimal value from the following tables directly into the program. Alternatively, it is possible to compare the return value by subtracting the &H40000 bit and then adding 1000 decimal. This is equivalent to subtracting decimal 261144 from the constant.
The following code snippet shows how to check if a warning is returned:
| If Err.Number =
CdoW_PARTIAL_COMPLETION - 261144 Then MsgBox "An error has occurred. Description: " & Err.Description & " Number: " _ & Err.Number End If |

Note that the Microsoft Visual Basic Scripting Edition and Microsoft JScript do not support any predefined constants. If your application is running as server-side script (e. g. a Microsoft Active Server Pages application or a Microsoft Exchange Scripting & Routing script) or client-side script (e. g. in a Microsoft Outlook form), you must use the appropriate hexadecimal or decimal values instead of the type library constants.
