2519 (09D7) (RC2519): MQRC_SELECTION_STRING_ERROR

Explanation

The SelectionString must be specified according to the description of how to use an MQCHARV structure. Examples of why this error was returned:
  • SelectionString.VSLength is greater than zero, but SelectionString.VSOffset is zero and SelectionString.VSPtr is a null pointer.
  • SelectionString.VSOffset is nonzero and SelectionString.VSPtr is not the null pointer (that is, it appears both fields are being used where only one is allowed).
  • SelectionString.VSPtr is not a valid pointer.
  • SelectionString.VSOffset or SelectionString.VSPtr points to storage that is not accessible.
  • SelectionString.VSLength exceeds the maximum length allowed for this field. The maximum length is determined by MQ_SELECTOR_LENGTH.

Completion code

MQCC_FAILED

Programmer response

Modify the fields of the MQCHARV so that it follows the rules for a valid MQCHARV structure.
