SetCustomField Method
Sets a custom field value within QuickBooks.
Syntax
int SetCustomField(const QString& qsFieldName, const QString& qsFieldValue);
Remarks
This method requires QuickBooks 2004 or above, with QBXMLVersion set to at least "3.0".
This method will immediately set the value of a QuickBooks custom field, which has been defined by the user from within the QuickBooks UI. Before calling this method, the preceding operation must retrieve the object from QuickBooks, using Get, ObjSearch, etc. Then, you may use SetCustomField to set custom field values (the fields will be modified or added, as appropriate).
Note that invoking this method will create a connection to QuickBooks if one is not already in place.
Error Handling
This method returns a 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. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
