dHTML/JScript - How to simulate a timed message? (OpenInsight Specific)
At 04 AUG 2000 12:39:29PM Wilhelm Schmitt wrote:
Our web application uses 2 access ways to data:
- Typing the key (immediate response within 2-3 seconds). No problem.
- Searching index (may take more than 15 seconds). After 5 seconds many users get nervous … and update the page, starting over again.
When searching the index, I would like to post a message for several seconds saying something like "Please wait. Processing request…" and then start the process.
Questions:
a) Is there a way to do that in HTML/JScript?
b) Would it be possible to chain the process directly through OI?
(1) Display waiting message (HTML)(2) Search the index (RBasic)(3) Display search results (inet_rlist HTML)Any suggestions?
Regards
Wilhelm

Chaining the routine back through OICGI is going to be the hardest part, since it can only handle one request at a time. You could send a post event to an open window to process the selection script or have the system work in two parts.
The simple way is have the script return a document that informs the user of the time delay, then instantly sends back a request to do the real search. The results of the search will return back and replace the screen.
More complicated is to send off the post event to execute the selection. Since you;ll have no control of the INET_GATEWAY from here, you'll have to write the final response doc out to a file/record somewhere. The "please wait" window will have to return requests searching for this doc, returning if it finds its, rediplaying the please wait message otherwise. All the post event will do is split the process, as it will never be able to check the request since the select will be processing, By the time the check request is executed, the select must have finished.
will reload the current page every 5 seconds, for what it's worth in this situation.
Most complicated is to work with hidden frames, use them to handle the requests back and forth, then use JS to shut down the "message" window informing the user to wait.
This would be easier if OICGI could process more than a single request at a time. Luckily, we don't have this problem at Sprezz.

Are you saying OICGI can't have more than one thread going at any one time?

OICGI is a 32 bit process which communicates with OpenInsight and OpenInsight is single threaded. So if it is processing one web request all other users are blocked out until that request has finished executing. This places severe restrictions on internet program design.

I totally agree - that is a near unworkable situation in many instances. I find it interesting that the sample Golf application is a retail style store which would be most inappropriate for a scenario like this.
Can you give me some idea how you work around it, or should I contact you directly?
TIA
James.

This means, that you either:
1) know about some undocumented features
2) have an add-on to OI
3) have a replacement for the OICGI
4) do not use OI at all for your web-applications
Could you be a little bit more specific?
