Hello,

I've created a script in Visual Basic in order to change the parameters of my  50 objects in HMI.  I receive no errors and warnings in TIA PORTAL window but get the following warning  from Visual studio Just-In-Time-Debugger : "An unhandled exception ('no screen item 'Circle_51'; please check transfer of names option.') occurred in HmiRTm.exe [12092]."  All in all the script works fine but every time i load it the warnings from the Debugger are displayed. Here's my simple script:

Question: Is there something wrong with my loop? The conditions shouldn't alow to get an index of Circle that equals 51. Any ideas? I'm just a newbie when it comes to VB :)

Regards.

Hello jb99,

does it work if you use "AND" instead of "&"?

"&" is an Operator to add strings in VBS, "AND" is used as a logical operator.

How big is "Nr_Elements"?

It was just as you mentioned H.J. and Murof. I just used 'AND' instead of '&' and everything is fine now. Such a simple mistake. Thanks guys for your asnwers.  

New question published by yosri2 is split to a separate thread with the subject Visual Studio "An unhandled exception occured".
