The CXADO.DLL library functions typically return one of the internal error values as defined in ADO.INC. These are defined as follows:
const ADOERR_NRARGS ="-1"; # Bad number of arguments passed to the function
const ADOERR_BADPARM ="-2"; # One of the arguments passed to the function was invalid
const ADOERR_TOOMANY ="-3"; # Exceeded the maximum number of concurrently open connection or recordset handles
const ADOERR_ALLOC ="-4"; # Memory allocation error (out of memory)
const ADOERR_NAMEDUP ="-5"; # Name has already been used for connection or recordset
const ADOERR_TOOLONG ="-6"; # Query/command/connection string exceeded the limit of 2047 characters
const ADOERR_CMDCLASH ="-7"; # Attempt to execute a command whilst another asyncronous command is in progress
const ADOERR_NOTOWNER ="-8"; # Attempt to access a private connection or recordset handle
const ADOERR_INVLDNAME ="-9"; # Named connection or recordset not found
const ADOERR_BADHANDLE ="-10"; # Invalid connection or recordset handle
const ADOERR_NOTREADY ="-11"; # Attempt to execute a function on an unopened connection or recordset
const ADOERR_COMERR ="-12"; # An ADO error occurred access adoLastError() to obtain error value
If the function returns the code ADOERR_COMERR then the underlying ADO error value is stored in the task structure for the task that made the original call and can be obtained through the adoLastError() function.
