GetCustomField Method
Gets a custom field value from QuickBooks.
Syntax
QString GetCustomField(const QString& qsFieldName);
Remarks
This method will get the value of a custom field, which has been defined by the user from within the QuickBooks UI.
To read the values of custom fields, be sure to set QBXMLVersion to at least "2.0" when retrieving data from QuickBooks. Then, QuickBooks will return custom field information, and it will be accessible through this method.
You may also invoke Config to read the value of custom fields. However, to set the value of custom fields you must set QBXMLVersion to at least "3.0" and invoke SetCustomField.
Error Handling
This method returns a String value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.
