How do I activate an HTML Help FIle on Button click ?

Expand Post »

I already have web pages written in HTML that give out Help info about various functions of the application.

How do I get them to pop up when the user clicks a button on the VB.NET form ?

Private Sub btnHelp_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnHElp.Click

??

End Sub

I managed to do something like this in the meantime >>

Private Sub MenuItem1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MenuItem11.Click

Try
Process.Start("IExplore.exe", "C:/....../bin/GettingStarted.htm")
Catch
MsgBox("Error launching Internet Explorer")
End Try

End Sub

Re: How do I activate an HTML Help FIle on Button click ?

I use another form with a webbrowser on it. On the form I have a property:

VB.NET Syntax (Toggle Plain Text)
    Public WriteOnly Property HelpFile()
        Set(ByVal value)
            Me.WebBrowser1.Navigate(value)
        End Set
    End Property
    Public WriteOnly Property HelpFile()
        Set(ByVal value)
            Me.WebBrowser1.Navigate(value)
        End Set
    End Property

In the button or menu click event I put the path and file I want to show.

VB.NET Syntax (Toggle Plain Text)
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Form2.HelpFile = "d:\mywebs\vbnet.html"
        Form2.ShowDialog()
    End Sub
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Form2.HelpFile = "d:\mywebs\vbnet.html"
        Form2.ShowDialog()
    End Sub

Hope this help some.
