What's the difference between add a device manually and dbCreateInst? It caused formInitProc failed ..

ArthurLinMTK

Dear Andrew:

The most callback work well after I create the instance by dbCreateInst, but when I created the cell with formInitProc, it got the error message - Can't modify attributes of effective CDF parameters, then I can't trigger the callback normally.


I've tried call the function first,as PasCdfFormInit(cdfgData) , and I got the error message "Can't modify attributes of effective CDF parameters"


But if I create the instance manually, the formInitProc function could be run normally, so I think there are some functions be trigger when we add the instance and select to open a CDF form.

What should I do to (after dbCreateInst and before call formInitProc) to make the formInitProc run just like we add an instance and 'q' it manually?  Thanks a lot..

Best Regard,

Arthur

  • Arthur,

    Are you using abInvokeCdfCallbacks or CCSinvokeCdfCallbacks (two different versions of the same code of mine) to trigger the callbacks after creation with dbCreateInst? They have explicit options to help solve this problem, so I'm trying to understand where you're starting from.

    Kind Regards,

    Andrew.
