Hi,
how can I combine following conditions, for better transparency

----------------------------------
void Station2_M700_ValueChange(System.Object sender, Neo.ApplicationFramework.Interfaces.Events.ValueChangedEventArgs e)
{
ScriptModule1.Start();
}

void Station2_M710_ValueChange(System.Object sender, Neo.ApplicationFramework.Interfaces.Events.ValueChangedEventArgs e)
{
ScriptModule1.Start();
}
----------------------------------
Like this ... ? ->

"Station2_M700_ValueChange or Station2_M710_ValueChange"
{
ScriptModule1.Start();
}
----------------------------------
Thanks for reply

Joe

Create a function that calls ScriptModule1.Start(). Then use that function in both of your ValueChange events.

You are free to create your own functions in a screen script. You do not have to use ours.

Code: Select all

namespace Neo.ApplicationFramework.Generated
{
    using System.Windows.Forms;
    using System;
    using System.Drawing;
    using Neo.ApplicationFramework.Tools;
    using Neo.ApplicationFramework.Common.Graphics.Logic;
    using Neo.ApplicationFramework.Controls;
    using Neo.ApplicationFramework.Interfaces;
    
    
    public partial class Screen1
    {
		
		void Button1_Click(System.Object sender, System.EventArgs e)
		{
                       MyFunction();
		}
		
		void MyFunction()
		{
			ScriptModule1.Start();
		}
		
    }
}

A slightly different option is the one I use. I create 1 single ValueChanged event, or manually create a function with matching signature. Per your existing convention.

Code: Select all

void Station2_Mxxx_ValueChange(System.Object sender, Neo.ApplicationFramework.Interfaces.Events.ValueChangedEventArgs e)
{
    ScriptModule1.Start(); 
}

Now from the script editor for Tags you can right click each tag you wish to use this ValueChange event code, and "Hookup existing..."

You can also cast "sender" to a GlobalDataItem if you want to gain access to the Tag's name, Gain, or Value for further specific function upon the change in value.

For Example, Assuming 4 Tags [Tag1 ... Tag4] are created, each assigned the same event handler.

Code: Select all

void Station2_Mxxx_ValueChange(System.Object sender, Neo.ApplicationFramework.Interfaces.Events.ValueChangedEventArgs e)
{
    GlobalDataItem tag = (GlobalDataItem)sender;
    if(tag.Name.Equals("Tag2"))
        MessageBox.Show("Tag2 Was Changed!");
}

You can now react to an individual condition (such as Name) depending on which tag was changed.

This is the methodology I use to create a central value change event handler and dispatch functionality to other Class Methods depending on the desired behavior I want.
