.Net Control in WinCC v7.2 - create a UserControl with public property

Hi ,I have a problem with the .net controls :

I development with Visual stusio 2010 in VB.net.

I have create a UserControl with public property :

Public Property S_CounterReset_1() As Boolean

Get

Return _S_CounterReset_1

End Get

Set(ByVal value As Boolean)

_S_CounterReset_1 = value

In Wincc environment , I,assign a variable to the property.

With my control i read this variable, but if i assign a value in net at this property , in Winncc don't change .

Thank's

new subject after Splitting from How to use .Net Control in WinCC v7.2

When i change value from one property in .netControl (at runtime),  in WinCC the associated variable don't changes value . I already  tried to raise an event , and in this way working properly, but I can not pass values ... 

In .Net code i ha some public property that to run time i change from .Net Control.

In Wncc my .netControl have the varible has variables associated , but form net i'm be able to read the change of them but if i change a value from net in winncc the associated variables don't change.

I need to change a integer/string variable and in this case i can't use the net event ...

Es.: 

Public Property S_CounterReset_1() As Boolean
        Get
            Return _S_CounterReset_1
        End Get
        Set(ByVal value As Boolean)
            _S_CounterReset_1 = value
        End Set
    End Property

 Private Sub ButtonStartLine1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ButtonStartLine1.Click

        Me._StartLine1 = Date.Now
        Me.LottoInCorso_1 = True
        Me.S_CounterReset_1 = True
        Me.LabelSTL1.Text = _StartLine1
        Me.LabelETL1.Text = ""
        Me._IdLottoLine1 = Insert_ProductionBatch("LINE 1", -1, _StartLine1)

    End Sub

Thank's

The way I solved this was to have my .Net user control raise an event that WinCC can see. Before raising the event I set the values of the .Net values I need WinCC to see.

I then used code like this in the WinCC event handler to set the .Net property values to WinCC's tags.

HMIRuntime.Tags( "TagName" ).Write ScreenItems( "NetControlNameSetInWinCC" ).MyControlValue

where NetControlNameSetInWinCC is the name of the .Net control in the WinCC screen and MyControlValue the public get,set propery in the .Net control containing the value that is needed to be passed on to a tag in WinCC.
