[RESOLVED] Passing a new string value to an open form

[britt13]

(v2008) I need to pass a new string value (and other data) from a second instance to a form that is already open. I'm setting a new string value as the command line in StartupNextInstance. Here is my code in ApplicationEvents:

            
        Private Sub MyApplication_StartupNextInstance(ByVal sender As Object, ByVal e As Microsoft.VisualBasic.ApplicationServices.StartupNextInstanceEventArgs) _
        Handles Me.StartupNextInstance
            strCommandLine = e.CommandLine.Item(0)
            frmStartup.MainText = strCommandLine
            e.BringToForeground = True
        End Sub

Here is my code in the startup form (frmStartup):

    
Public Property MainText()
        Get
            Return TextBox1.Text
        End Get
        Set(ByVal value)
            TextBox1.Text = value
            TextBox1.Update()
        End Set
End Property

During debug, it appears as though TextBox1 does in fact get set to the command line string as expected, but it doesn't display on the form.

Help!
