Hello, I am trying to access a textbox value programmed in visual studio in the tia portal and it always stays at 0 and does not update in real time. Could you tell me how to "update" that value?

Code: 

Thank you.

Greetings.

Hi, I was dealing with some similar issue yesterday. How to trigger externally a method in my usercontrol. I did it in this way:

 1) Add a dummy variable in your Usercontrol like this

[Description("Dummy variable to trigger method"), Category("InternalDoNotTouch")]

public string SendEmail

{

get { return ""; }

set { if (string != "") SendEmail_implementation(value); }

}

The method void SendEmail_implementation(string text) in your usercontrol contains the "how" you send the e-mail.

 2) Use a C Script in Wincc to set the Dummy variable to the desired value

#include "GlobalDefinitions.h"

void FuncionC_1()

{

SetPropChar("Image","UserControl_1","SendEmail","Alarm 123 has been triggered");

}

 

I'd like to know how did you do this:

1. Wrote a small C script to extract the alarm text on the "Status changed" event.  This works just fine.
