VB.NET Syntax (Toggle Plain Text)

Private Sub Button9_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button9.Click
  If OpenFileDialog1.ShowDialog = Windows.Forms.DialogResult.OK Then
    WebBrowser1.Navigate(OpenFileDialog1.FileName)
  End If
End Sub

Private Sub Button9_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button9.Click If OpenFileDialog1.ShowDialog = Windows.Forms.DialogResult.OK Then WebBrowser1.Navigate(OpenFileDialog1.FileName) End If End Sub

now it may or may not open and show the file in the control. If you try to open exe or similar file, you'll get IE's "Run/Save/Cancel" -dialog.

What custom settings? Please, be more specific.

In your code you set and save the setting:

My.Settings.Item("SliderOpacity") = 15
My.Settings.Save()

My.Settings.Item("SliderOpacity") = 15 My.Settings.Save()

and read the setting:

Dim Opacity As Integer
Opacity = CInt(My.Settings.Item("SliderOpacity"))

Dim Opacity As Integer Opacity = CInt(My.Settings.Item("SliderOpacity"))
