Questions on forms

Hello,
I am currently converting a plugin from a standalone VB .net application to Add In Express.

I came up with two questions which I could not solve on my own :oops:
Question a)
I tried adding and showing a simple vb windows form. For this matter i used the following code:

Dim frm As Form1 = New Form1()
frm.ShowDialog()

=> Very simple. However, when I run it it does not work when run from the IE toolbar. It shows the form and immidiately hides the form again. When I run the same code from a context menu button, it works w/out any problems. Why is that?

I also tried using frm.Show(), that does show the form, but in the background.

I use Windows Vista x32 with Internet Explorer 8 and MS VB .net in VS 2008.

Question b)
I have a windows form with a link on it. When the user clicks the link, IE is supposed to navigate to the uRL on the link. How do I access the IEApp object from a vb form? I tried using IEModule.IEApp.Navigate(...), but IEModule.IeApp is not available.


Thanks for your reply in advance

Hello Stephan,

1. Try using frm.ShowDialog(IWin32Window) overload. Use ADXIEModule.MainWindowHandle to initialize the class implementing IWin32Window.

2. You can create a constructor accepting ADXIEModule.

Hey Andrei,
thanks for your reply! I am progressing with my addin very well.

Tip #2 worked very fine for me, however I have trouble implementing tip #1. How do I set up a wrapper class in VB .net to make that possible? Could you give me an example? My tries unfortunately did not result in success.

Furthermore I came up with a new question:
I configured some shorcuts for my context menus. However, none of them work - although I tried using combos that are not used by IE (e.g. CTRL+SHIFT+N). Although they are correctly displayed in the context menu, when I push the combination nothing happens.

I also have to correct myself. I am using IE7, not IE8. So IE7 on x32 Vista with VB .net 2008.

Thanks in advance for your help :D

Public Class MyWindow 
    Implements System.Windows.Forms.IWin32Window 

    Dim theHandle As IntPtr 

    Public Sub New(ByVal aHandle As System.IntPtr)
        theHandle = aHandle 
    End Sub

    Public ReadOnly Property Handle() As System.IntPtr _
        Implements System.Windows.Forms.IWin32Window.Handle
        Get
            Return theHandle
        End Get
    End Property
End Class

Please check if you set HandleShortcuts = tue in the properties of the IE module.
