[ozi]

Hi,
I need write and read value of variable in the VSTA, when I use VB.Net language. Can somebody write code in VB.Net. Thanks

Hi ozi,

There are several examples here in this forum, mostly in C#, that can be adopted for use in VB.NET.

Use the search function for "get_value". One example with an online container can be found here:

This VB.NET macro will read the value of the variable with the name "return_numeric" and write it to the output window.

   Public Sub Macro_ReadValue()
        Dim obVar As zenOn.IVariable
        Dim vValue As Integer
        obVar = Me.Variables.Item("return_numeric_1")
        If Not obVar Is Nothing Then
            If obVar.IsOnline() Then
                'safe to read, variable exists and has a valid value
                vValue = obVar.get_Value(0)
                System.Diagnostics.Debug.Print(vValue.ToString())

            Else : System.Diagnostics.Debug.Print("variable has no valid value")
            End If
        Else : System.Diagnostics.Debug.Print("variable does not exist")
        End If
    End Sub
