NON Fatal run time error-Library function error(return value -13,invalid control ID)

[shishen yang]

 I have using this command which is  

SetAttributeForCtrls(ui, ATTR_DIMMED, 1, 5,
            PANEL_LISTBOX, PANEL_COMMAND_SET, PANEL_COMMAND_RUN_TESTS
            ); on the LabWindows/CVI(2009) at main.c at line 1169,1180 & after running Debugxx.exe for my project that get NON-FATAL run time error message which indicated library function error,return value is -13 -invalid control ID,my question is what is meaning for invalid control ID & how to step by step to debug this error,until found the root cause?

Thank you foor your help!

Not sure that this can be the reason for this error (I can't test on a CVI machine at the moment) but there is an evident typo in your code: you are passing 5 in numberOfCtrls parameters but then you are passing 3 controls IDs only.

Unless you set 0 as numberOfCtrls parameters (in which case you must add a zero parameter to mark the end of the list), numberOfCtrls must match the number of contrl IDs passed to the function.
