My experience with VB6 is limited, but, what you're asking for is very simple. Here's what you'd do in later versions.
* In your IDE, open the Toolbox
* Find the Webbrowser control and drag it on your Form. ( If you can't find the control, right-click on the toolbox and add it, as a new item.)
* Drag a button on the Form also.
Ensure the controls are named as webBrowser1 and Button1 (for this example to work).
In the click event for the button, you need to tell the browser where to go:
Private Sub button1_click(sender as object, e as eventargs) Handles Button1.click
webBrowser1.navigate("Your web page")
In VB6, the handler will look a little different.
Are you really using VB6? If so, why? It's quite an old language now...
May I suggest a trip to MSDN
Hope this helps you.
