Hi,

I would like to know if it is possible to execute js functions while i'm processing a large procedure.

I've a frameset where in the top frame appears a loading message, and in the main frame I process my focexec, when it is finished it changes the body size of the top frame and make it disappear, but I would like to send messages to the top frame like: 'First part of your request is processed (Include 1)', 'Second part processed', etc.

Is there any way to do what i want??

Thanks!!!

NO.

WebFocus does not return anything to the browser until the request is finished.

Because it is a non persistent connection you cannot return an interim status.
Trying to do so means’ everything you have done so far is lost.

I've never done this, but here is an idea:

Allocate a text file.

After each
...
END
-RUN

add a -WRITE into a file.

If JavaScript can read the text file, display the contents of the text file in the frame.

Don't know if this will work...

Here is an idea. Only an Idea. you could break up your procedure into seperate steps (where you want to show a message), at the end of each step be an -HTMLFORM statement with a message to display back to the user and some javascript code the execute the next step. Be sure you create unique files for each step for each user and use them in the next step. This may be a lot of work but may give you what you want. If it were me, I would just try to display a page that says processing your request, and maybe put an animated gif on that page. Using the first technique does have it benefits if the request is a long processing request because after each step is completed the browser fires off the next request which will help prevent browser time outs. If you do get the first suggestion working please post the code here for other users. Hope this idea helps.

Having said NO the responses have given me a nudge.

When you call your focexec pass a unique identifier for use as a file name.

In this file which is an html page to be displayed in the top frame, you write the status at each process step.

The top frame has a time based auto refresh reloading the html file and so your status is updated.

The file obviously must be written to a directory visable to the browser and will need deleting to prevent
a build up of rubbish.

The easiest way to do this would be to have an action in the top frame that ran a focexec that issued a !del file or !rm file dependant on the OS.
