Hello to all. i use TiaPortal v17 and Wcc professional.

My question is the follow: into my project i have 2 screen window. This screen window are contained to other screen window. 

to do an example the first screen window display a PAGE 1 and the second screen window display  PAGE 2

Into PAGE 1 i have a pushbutton. Into PAGE 2 have a  I/O field . Usualy The I/O field is not visible.

I would like modify the "visible" property of I/O field into PAGE 2 from button into PAGE 1

It's necessary use a C language because the project is already run and some button are already

existant with C language script. I need only to add a new code

I do not want use a internal tag to do this i would like write directly the property.

GetParentScreen or GetParentScreenWindow i can reach the screen window, not the displayed screen and related object

Thank you in advanced 

Fabio

Hi,

Based on your description, I have made a sample that does what I think you want.

See the attached two printscreens in zip file.

They show a sample script with one start screen containing two picture Windows (called "scrWin1" and "scrWin2").

In each Window is a picture "page1" and "page2".

In page1 are two buttons containing the same c-script. One sets the IO field "Visible" property to FALSE, the other to TRUE. Printscren 02-page1clickevent.PNG show the script that sets it to invisible.

I hope it helps.

A thousand thanks . It's exactly what I was looking for. You solved a big problem for me

Thank you again

Fabio
