vb.net open link in new IE11 tab (instead of window) - vb.net

Question

I need to force my application to open few links (there are few buttons - one link under one button) in IE11 (regardless if it's set as default browser or not).
I tried multiple ways, but the result is always the same like with:
Process.Start("iexplore.exe", address)
It works perfectly for Firefox, or Chrome, but for IE - it always opens new window for each link. Regardless IE is already opened or not.
Few years ago I wrote similar thing which worked with IE7 I guess...:
Imports SHDocVw
Dim internetExplorerInstances As New ShellWindows()
Dim foundIE As Boolean = False
foundIE = False
For Each ie As InternetExplorer In internetExplorerInstances
If ie.Name = "internet explorer" Then
ie.Navigate(address, &H800)
foundIE = True
Exit For
End If
Next
If Not foundIE Then
With oPro
.StartInfo.UseShellExecute = True
.StartInfo.Arguments = address
.StartInfo.FileName = "iexplore"
.Start()
End With
End If
But today, with IE 11 it doesn't work.... I mean it still opens URLs in new windows.
Do you have any ideas how to programatically force IE11 to open link in new Tab, not in new window?

Answer 1

Generally above code is OK except one detail - it should be:
If IE.Name = "Internet Explorer" Then... it is case sensitive.
Finally my code looks like this:
Imports SHDocVw
Const openInTab As Object = &H800
Dim internetExplorerInstances As New ShellWindows()
Public Function IsProcessOpen(ByVal name As String) As Boolean
For Each clsProcess As Process In Process.GetProcesses
If clsProcess.ProcessName.Contains(name) Then
Return True
End If
Next
Return False
End Function
(...)
And call:
If IsProcessOpen("iexplore") Then
For Each IE As InternetExplorer In internetExplorerInstances
If IE.Name = "Internet Explorer" Then
IE.Navigate2(address, openInTab)
Exit For
End If
Next
Else
Process.Start("iexplore", address)
End If
And it works :)
