Hello, I am struggling to print a web page from a VB.NET terminal application. Basically, when our system sees a command in the database, it prints off a web page based on the value of that command. The problem I am having, is calling a web browser control gives me an ActiveX error about the application not having multiple threads.

Any code snippets for this would be really appreciated.

I just did a test in my vb.net 2005.  I added a WebBrowser control to the form, set it the url to both a url and to a html file, then executed
Me.WebBrowser1.Print()
for both types of pages and it printed find.  Are you trying to print it from a background worker?

If trying to print from a thread, implement something similar to this:
 
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
    Me.WebBrowser1.Print()
    If Me.WebBrowser1.InvokeRequired Then
      Me.WebBrowser1.Invoke(New MethodInvoker(AddressOf printbrowser))
    Else
      WebBrowser1.Print()
    End If
  End Sub

  Private Sub printbrowser()
    Me.WebBrowser1.Print()
  End Sub

Open in new window

delete the first me.webbrowser1.print from the code above at line 2.  I forgot to remove it.

Sorry, both of you seem to have missed (though this is my fault) that this application is a Terminal application, or a Console application in VB.NET terms. Sorry, but thank you for trying.

Does it have to be console app?

One option is to develop another winforms based app which you can launch from your console app. That app can use the webbrowser and print the web page.

I am thinking of just moving from a console app to a winforms app. As nice as it is having a nice simple system, I think it is time to move to winforms as the solution.

Thanks for all your help.

Shame there was never a full solution, but still made me see what had to be done.
