GetErrorInfo method

Use this method to retrieve additional information about the failure immediately after another method in the interface fails.

Syntax
DBSC_ErrorInfo GetErrorInfo()
Returns

Returns a pointer to a DBSC_ErrorInfo structure that contains information about the failure. The contents of this structure may be overwritten the next time any class method is called. The DBSC_ErrorInfo structure is defined as follows:

 public struct DBSC_ErrorInfo
  {
    public DBSC_ErrorType type;
    public String str1;
    public String str2;
    public Int32 val1;
    public Int32 val2;
    public UInt32 hdl1;
  }
Remarks

The type field contains a value that indicates the reason for the failure. Currently, type may take the following values:

Type value Description
DBSC_ERR_OK

No error occurred.

DBSC_ERR_NOT_INITIALIZED

The class has not been initialized by calling the init method.

DBSC_ERR_ALREADY_INITIALIZED

The init method was called on a class that was already initialized.

DBSC_ERR_NOT_CONNECTED

No connection to a dbmlsync server is in place.

DBSC_ERR_CANT_RESOLVE_HOST

Cannot resolve host information.

DBSC_ERR_CONNECT_FAILED

Connection failed.

DBSC_ERR_INITIALIZING_TCP_LAYER

Error initializing TCP layer.

DBSC_ERR_ALREADY_CONNECTED

Connection failed because a connection was already in place.

DBSC_ERR_PROTOCOL_ERROR

This is an internal error.

DBSC_ERR_CONNECTION_REJECTED

The connection was rejected by the dbmlsync server.

DBSC_ERR_TIMED _OUT

The timeout expired while waiting for a response from the server.

DBSC_ERR_STILL_CONNECTED

Could not Fini the class because it is still connected to the server.

DBSC_ERR_SYNC_NOT_CANCELED

The server could not cancel the synchronization request, probably because the synchronization was already in progress.

DBSC_ERR_INVALID_VALUE

An invalid property value was passed to the SetProperty method.

DBSC_ERR_INVALID_PROP_NAME

The specified property name is not valid.

DBCS_ERR_VALUE_TOO_LONG

The property value is too long. Properties must be less than DBCS_MAX_PROPERTY_LEN bytes long.

DBSC_ERR_SERVER_SIDE_ERROR

There was an error on the server.

DBSC_ERR_CREATE_PROCESS_FAILED

Unable to start a new dbmlsync server.

DBSC_ERR_READ_FAILED

Error occurred while reading data from the dbmlsync server.

DBSC_ERR_WRITE_FAILED

Error occurred while sending data to the dbmlsync server.

DBSC_ERR_NO_SERVER_RESPONSE

Failed to receive a response from the server that is required to complete the requested action.

DBSC_ERR_UID_OR_PWD_TOO_LONG

The UID or PWD specified is too long.

DBSC_ERR_UID_OR_PWD_NOT_VALID

The UID or PWD specified is not valid.

DBSC_ERR_INVALID_PARAMETER

One of the parameters passed to the function was not valid.

DBSC_ERR_WAIT_FAILED

An error occurred while waiting for the server to shutdown.

DBSC_SHUTDOWN_NOT_CALLED

WaitForServerShutdown method was called without first calling the ShutdownServer method.

DBSC_ERR_NO_SYNC_ACK

A synchronization request was sent to the server but no acknowledgement was received. There is no way to tell if the server received the request.

DBSC_ERR_CONNECTION_REJECTED

str1 points to a string returned by the server which may provide more information about why the connection attempt was rejected.

DBSC_ERR_NO_SYNC_ACK

hdl1 is the handle for the sync request that was sent. If the server received the request, this handle can be used to identify events for the synchronization retrieved using the GetEvent method.

DBSC_ERR_SERVER_SIDE_ERROR

str1 points to a string returned by the server which may provide more information about the error.

str1, str2, val1, val2 and hdl1 contain additional information about the failure and their meaning depends on the type value. For most type values there is no useful information in any of these fields. The exceptions are:
