How Do I open a website URL in 'Pop Up Mode' from a form in access.

[Nod_Swerdna]

I am writing a program that allows users to enter customer info and I want to be able to pop up a window that will search for Postal (Zip) codes using the Postal Service URL. (I would like to position the popup so that the contents of the Address and Postal Code fields are still visible on the form). I would also like to know if there is a way to copy the contents of the Address Field in my program to the Windows Clipboard, using VBA code, so that I can paste it into the Postal Code Finder without highlighting the field contents and pressing Ctrl-C.
Thank you so much for your help in advance...

I built a form with boxes for each item
street #
street name
street type (ave, st, way)
city
state

In the form I added the activeX control , microsoft web browser , when the user click the find button, it builds the URLstring to the browser...

Private Sub btnFind_Click()
Dim vUrl
    Dim strURL As String
    Dim objIE As Object

    strURL = "http://www.yahoo.com"


vUrl = "https://tools.usps.com/go/ZipLookupResultsAction!input.action?resultMode=0&companyName=&address1="
vUrl = vUrl & txtNum & "+" & txtStreet & "+" & txtStType
vUrl = vUrl & "&address2=&city=" & txtCity
vUrl = vUrl & "&state=" & cboState & "+"
vUrl = vUrl & "&urbanCode=&postalCode=&zip="

    Set objIE = Me.WebBrowser1.Object
    objIE.Navigate vUrl

End Sub

Thank you for your help with this problem. I don't completely know how to adapt your code to my program, but I will try it as soon as I get a chance and I'm sure I can work it out. Thanks again...
