Interop.SHDocVw not found, after added as reference

[Mark]

I am trying to take a working VB.NET program (the SHOW HTML program
from the Halvorson book) and pass in parameter values which are used to
build the URL that IE looks up.

The original program works with a fixed URL, such as
"http://www.microsoft.com". Interop.SHDocVw is part of the original
program.

However, when I bring in values from outside the program, the url
string is built correctly, but the program crashes saying:

"File or assembly name Interop.SHDocVw, or one of its dependencies,
were not found."
Any help resolving this would be greatly appreciated.

This seems quite a common problem & each seemed to be resolved by viewing
this document:

http://support.microsoft.com/default.aspx?scid=kb;en-us;834610

It addresses a FileIOExecption error.

Let me know if this helps

Mark,

In the way you describe it, it should not crash, are you sure you set a
complete url in it including the http://

Yes. I can paste the new url in and it works fine (in the original
program). The problem seems to be where the call to IE happens after
the parameter values are passed in. It never gets launched.
I have used the MessageBox.Show method to show me the values on the
screen as the program executes, and they all get passed in OK.

I must mention that this is VB.NET 2003, and that I have included the
Interops.SHDocVw library, but it doesn't work. Overall, I'm not
impressed with the whole Interops library concept, but that is another
discussion.

Crouchie1998,
I went to the support site you listed, and couldn't understand what it
was trying to tell me. I'm not that sophisticated or experienced in
VB.NET yet. Thanks for your help, though.

Mark,

You don't believe it, however I don't have the Halverson book.

Can you show what is so special on it.

Here is the original code:

Public Class Form1

#Region " Windows Form Designer generated code "

Public Sub New()
MyBase.New()

'This call is required by the Windows Form Designer.
InitializeComponent()

'Add any initialization after the InitializeComponent() call

End Sub

'Form overrides dispose to clean up the component list.
Protected Overloads Overrides Sub Dispose(ByVal disposing As
Boolean)
If disposing Then
If Not (components Is Nothing) Then
components.Dispose()
End If
End If
MyBase.Dispose(disposing)

'Add a few useful Web sites to the combo box at startup

ComboBox1.Items.Add("http://msdn.microsoft.com/vbasic")
ComboBox1.Items.Add("http://www.devx.com")
End Sub

End Class

'end of program

The problem occur when I put the following code in to build the URL
text that goes in the ComboBox1 object.

Dim MyStartupArguments() As String, intCount As Integer
MyStartupArguments = System.Environment.GetCommandLineArgs()
For intCount = 0 To UBound(MyStartupArguments)
myVariable1 = MyStartupArguments(1) 'Takes the first
argument off the command line
myVariable2 = MyStartupArguments(2) 'Takes the second
argument off the command line
myVariable3 = MyStartupArguments(3) 'Takes the third
argument off the command line
Next
This appears to block the initiation of the IE application.

Mark,

I looked at your code,

What is the purpose from those commandline arguments, which you get when you
start the program using a DOS box.

It does by the way in the way you show it nothing,
