Can VB force a javascript command on a web page? And if not, can a click event be forced on a gif if it doesn't have a name assigned to it?

I have a form on a web page that I need to populate and then submit. The gif has an onClick event that activates a javascript checkForm...the script then submits the form.

I either need to force a click event on the gif, or just activate the js script.

Thanks!

Private Sub Command1_Click()
    Dim iLoop As Integer
    For iLoop = 0 To WebBrowser1.Document.All.tags("IMG").length - 1
        If WebBrowser1.Document.All.tags("IMG")(iLoop).src = "file:///c:/test.bmp" Then
            WebBrowser1.Document.All.tags("IMG")(iLoop).Click
        End If
    Next iLoop
End Sub
Private Sub Form_Load()
    WebBrowser1.Navigate "c:\test.html"
End Sub


The above searches for an IMG and if it's src (location of image) is "file:///c:/test.bmp", it'll Click it. I had an OnClick javascript alert tagged to the image and it worked for me. It'd be more efficient if you could use IHTMLElementCollection but the above is fine also and you don't have to worry about an additional reference.

>> or just activate the js script.

Lack of questions and had too much sugar so..

There's a execScript method that allows you to either pass the actual javascript "code" to execute or just the name of a pre-existing function. Since you probably know the function name..

Private Sub Command1_Click()
    WebBrowser1.document.parentWindow.execScript "MyScript()"
End Sub
Private Sub Form_Load()
    WebBrowser1.navigate "c:\test.html"
End Sub

AmyL,

Are you looking to do this with an external VB program (i.e. a standalone Exe)  or are you looking for some vbscript you can add to the web page that'll accomplish this task?
