Error Codes

It's possible you'll see many different error codes show up in applications that you are developing. To find the descriptions for the error codes, you can check the Microsoft Developer Network Web site (http://msdn.microsoft.com/developer) and Table 3-4.

Visual InterDev uses the data environment object model, based on the Microsoft ActiveX Data Objects (ADO) object model, for accessing and processing database records. Table 3-4 lists the error numbers and descriptions that are returned by the ADO object model. You might also receive error messages that are generated from the database driver or from the database engine your application uses.

Table 3-4. A partial list of ADO error codes.
