Visual FoxPro 9.0 Service Pack 2 improves the capability of the AError() function for errors 1104 - Error reading file, and 1105 - Error writing file. For these errors only, the array produced by AError() contains additional error information consisting of the underlying operating system error number and error text. The error number and error text are stored in the AError() array, elements 6 and 7 respectively.

The explanation for the error isn't too helpful and even confusing as the error often shows up on computers with plenty of memory.

The error is related to the RowSource or ControlSource of a ListBox/ComboBox.

The WIN API FormatMessage function (among other things) can retrieve message definition from an already-loaded module or the system's message table. The error code usually is provided by the GetLastError WIN API function.
