passing parameters to the WebBrowser control in Outlook Form, (also ReadyState not changing)

I have embedded a WebBrowser control in a custom Outlook contact form
and have code that calls the navigate method to load a local .htm
file. I would like to be able to pass a parameter into the .htm file
which will help customize what is displayed based on the current
contact item.
The ultimate purpose being that ADODB will be used in the vbscript of
the .htm to create a report based on this parameter.

I first tried passing the following to the Navigate method,
"C:\SaarIQ\CMReports\default.htm?id=1"
But the parameters did not show up in the document.url, not even the
"?"

I then tried changing the value of a hidden textbox in the loaded .htm
file with the following code
Set objInsp = Item.GetInspector
objInsp.ModifiedFormPages("SaarIQ").WB.document.all.item("txtTest").value
= "1234"
Which threw a object required error. I then added a do loop to check
for the objInsp.ModifiedFormPages("SaarIQ").WB.ReadyState, which
resulted in an infinite loop.

In troubleshooting this I was able to receive the ReadyState = 4 after
a msgbox was used for variable testing.

It seems the WebBrowser.ReadyState variable is not changed within an
Outlook Form unless I use a msgbox.

I am running Office XP - sp2, so I was wondering if this was part of
the security patch.

Sorry for such a long message, I just wanted to bring you up to speed
on what I have currently tried.

I would appreciate anyones help in either
1) passing a parameter to the document in a webbrowser control
2) or why the ReadyState only changes with a message box, and if there
is a work around for this.

Thank you for your help,
Jeff

I solved the first part of my problem.

I was using document.url instead of location.search

Any help on the ReadyState value would still be much appreciateded.

Thanks,
Jeff
