Calling vbscript function from html button

Question

Don't be surprised if what I'm doing is completely wrong or if the solution is obvious.

<script type="text/vbscript">
    Function AddPrinter()
        Set objNetwork = CreateObject("WScript.Network")
        objNetwork.AddWindowsPrinterConnection "\\a2031slhsfile1\2031CAT-T113-HP4014dn"
        objNetwork.SetDefaultPrinter "\\a2031slhsfile1\2031CAT-T113-HP4014dn"
        MsgBox "The printer was added and set as the default printer."
    End Function
</script>

I added the above vbscript to an HTML document in the head section and one of the buttons has the following property:

onclick="AddPrinter()"

I didn't find much about this when searching on Google for an hour. What I did find didn't work. How does it know whether you're calling the function from javascript or vbscript or whatever anyway?

I get this error:

SCRIPT429: ActiveX component can't create object: 'WScript.Network'

You can't do that from a webpage.

Your Internet Explorer security settings prevent the creation of the ActiveX control. You need to allow "initialize and script ActiveX controls not marked as safe for scripting".

That's what I did to fix it but I forgot to come back to this question when I was done. Better late than never.

Hmm, WScript.Network works just fine in IE, at least up to version 8. As about OnClick, its default assignation (whether run JavaScript or VBScript) depend on script content in the page. If your page has scripts in both languages (JavaScript and VBScript), then JavaScript is default, i.e.:

onClick="MyFunc()" 'is equal to:
onClick="javascript:MyFunc()"

In seach case you'll need to use explicit language modifier to run your VBScript.

onClick="vbscript:MyFunc()"

But if your page contain only VBScript then that not necessary.

<html>
  <head>
    <title>Example</title>
    <script type="text/vbscript">
      Sub Hello()
          Set objNetwork = CreateObject("WScript.Network")
          If IsObject(objNetwork) Then
              MsgBox "Its working"
              MsgBox "Computer Name = " & objNetwork.ComputerName
          Else
              MsgBox "Not working"
          End If
      End Sub
      Sub btnTest2_OnClick()
          Hello()
      End Sub
    </script>
  </head>
  <body>
    <button onClick="Hello()">Test 1</button>
    <input type="button" value="Test 2" id="btnTest2">
    <input type="button" value="Test 3" onClick="Hello()">
  </body>
</html>

P.S. And if you not change your IE security settings, as Ansgar Wiechers suggest then you'll need to confirm (on first click).

Works in IE9 as well. And depending on the security level and/or manual zone configuration there won't be a prompt.

I added the vbscript: before the function and added all of those tests but it's still getting the same error. It's definitely not getting past the CreateObject("WScript.Network")

You may elect to bypass the security settings of the Internet Explorer completely by saving the file as an HTA rather than an HTML. HTA's are hyper-text applications that are written as htmls and use the Internet Explorer as a GUI, but are not restricted by the same security concerns as an HTML. the only change you need to make is change the file extension from *.html to *.hta.
