Returns a string containing an error message for the last database error that occurred.
If dwcontrol is null, the method returns null.
Call GetLastError and GetLastErrorString to get information about database errors that caused SetAction, Update, Retrieve, and RetrieveEx to return –1.
This code in a page server script calls Retrieve for the Web DataWindow server component called dwComponent and gets information about the database error if Retrieve fails:
retVal = dwComponent.Retrieve( );
if (retVal < 0) {
Response.Write("Retrieval error: "
+ dwComponent.GetLastError( )
+ "<BR>"
+ dwComponent.GetLastErrorString( )
+ "<BR>");
}
