Checking to see if internet stuff is finished

[Edwin Gore]

 Chipp,

Thanks, that's exactly what I was looking for.

Sorry about the html text - I didn't realize my webmail thingee did that.
Unfortunately, it doesn't have any setting to change that, and it's the only
way I can do personal email around the firewall at work - it blocks normal
web mail sites...

Thanks again,

Edwin Gore

only set after the data is finished being recived from the server. The same
is true with:

return data is not placed into the variable it until post is finished.

something like:
>
> on mouseUp
>    ImBusy
>    put URL "http://www.mypage.com?name=Edwin" into tXML
>    put tXML into fld 1
>    ImNotBusy
> end mouseUp
>
> on ImBusy
>    show img "spinningIcon.gif"
>    show btn "coverEverything"
>    put "Please wait...downloading URL" into fld "status"
> end ImBusy
>
> on ImNotBusy
>    hide img "spinningIcon.gif"
>    hide btn "coverEverything"
>    put "Successful download" into fld "status"
> end ImNotBusy
>
> Create a 'clear' button at the top layer which covers everything (except a
Stop/Reset button). When your app is looking for a URL, it will display this
button along with an animated GIF and a status string in a field at the
bottom of the page.
