Automatically Update HS3 device value from HSTouch

[wmcmath]

I have a text box in HSTouch that tracks the value of device A. Is there anyway to automatically update the value of Device A when the text box in HSTouch changes? I know I can setup an element in HSTouch, that when pressed, runs a script with values from elements that can update Device A's value, but this requires that the user has to click another element to force the update. I am hoping there is a way that HSTouch can automatically update Device A's value when the text box tracking Device A's value changes.

If you look at the text box as given below. You have an action when text changed. This is where you would update the device by calling a script. This is a text box not text.

I cannot get the ActionsWhenTextChanged ot work, here is what I tested:



Under Misc for the textbox Properties, EnterIsChange = True and IgnoreCHange = False

The Script to be run, HSTouchTextBoxChanged.vb is:

Sub Main(parm as string())
hs.writelog("HSTouch","Text Box Changed")
End Sub

When I changed the contents of the text box and press enter, no log entry occurs in the HS log.

Sub Main(parm as string())
hs.writelog("HSTouch","Text Box Changed")
End Sub

Just a warning here: Strings are passed differently between calling the script from an event and calling the script directly inside of HS3 Touch. Event just passes one string, HS3 Touch will pass an array of strings. Defining the subroutine one way will cause a parameter mismatch when called the other way.

Solution is to declare the parameter as an object, then decide in code whether it is a string or string array:

Sub Main(parm as Object)
  If parm.GetType().ToString = "System.String" then
    ' single string called from event
  Else
   ' String array called by HS Touch
  End If
  ...

Thanks, I will work on this and use your code
