Hello,

I need a "waiting screen" in CGI, i use vdsinet.dll
It's for a loginpage when the the cgi get all the date from a database, but that could takes up to 10 sec, so i want to display a message while the data is processed. Any idea's

<META HTTP-EQUIV="Refresh" CONTENT="0; URL=blablabla?value1=23&value2=34"> doesn't do the job.

Maybe you can do something like this:

When a user calls page1.exe, send the wait page with a refesh. Then let the refresh page call page2.exe. In the mean while, page1.exe should contact the database and write the value to a file (database.txt or something). When page2.exde is loaded, just send the database.txt file to the user.

I hope you understand me. If you don't, please contact me in some way, so I can explain in Dutch... Wink

That doesn't work (META HTTP-EQUIV="Refresh" CONTENT="blablabla.exe?v1=12&v2=34).

I try to do that but IE comes with a message box thats tell you to try again to send the value's and stay's on that page.

Looks like U added "Javascript" Confused

I think its different from java Question

I dont know anything in this field cgi etc but just wondering

That's Javascript indeed. Java can be used outside HTML files as well, so there are much more functions and commands which can show dialogs, open files, etc.

What I would do in this situation, is have the cgi program "WAIT 1" in a
loop. In that loop, I'd keep adding like the period character to the page
like a progress bar until whatever you are doing is complete, then leave
the loop and print whatever results.

This would require two exe's though. One is the main exe which the
browser is communicating with, and the other is the one that does the
search. Use your preferred method of communicating between the two
exe files.

But find out what the time out is on your server, as it is possible for
your waiting to exceed the time out and then your exe would be killed
by the server. Typically, I've seen 60 and 90 seconds as the most
common.

That "progress bar" doesn't work with vdsinet, it sends the page after the script stops.

The javaSCRIPT Smile

does the job very well now.
