TestWebClient freezing the app

[Alberto]

Hi,
I need to read data from some web pages.
For this porpouse I use the TestWebClient proc of the Demo Nettalk app.
I´ve modified it, hiding the window and commenting all diplaying lines.
It works ok.
Now I need to run the read process in the background.
Then I create a window proc with a timer that calls the TestWebClient proc.
I START that hidden window proc from the Frame but...
each time the timer calls the TestWebClient the entire app frezes until the read proces finished.
What am I doing wrong?
Thanks and happy new year!!!!

Hi Alberto, I won't be at my computer for a few days to dig up an example, but I think Bruce has a fairly new example that uses the Yield statement to do something similar. I actually was able to build a pretty slick "live" progress bar using this technique.

Perhaps you need to post an example here Alberto.

It's hard to comment on what you've done wrong without being able to see the code.

Ok, Bruce. no problem, but I need to sedn you the original app, it is pretty short.
Please, send me an emal so I can reply it attaching the files.
Thanks
Alberto

Bruce, I´ve send you the files. (C71, NTWS5)
Have you received it?
Thanks

Bruce,
It worked ok with the MDI window attribute but...
Every time the proc is called, (the window is hidden) the actual window looses its focus, I´ve tryed everithing but it stoles the focus.
Is there any way to concert the proc in a source proc?
I´ve been trying but I think the problem is to RETURN from the source proc from inside a procedure, once the page is loaded.
May you please give me a hand?
THanks

>> Is there any way to [create?] the proc in a source proc?

no, you need an Accept loop because the comms is Event driven.

If you set the window with the Toolbar attribute, or
after the window is opened set
0{prop:active} = 0
then I think it won't grab the focus.

Cheers

Hi Bruce,

The toolbar attribute make the app to freeze, like when it had not the MDI attribute.
The prop:active does not work.
I´ve tried posting an event:gainfocus to the browse but it does not work either.
Any other idea?
Thanks
Alberto

Bruce, coming back to this problem...

I´m calling the TestWebClient proc with another proc for it to read some web pages.
Then the calling proc parses it and fill a table with the data.
How can I do it inside the TestWebClient proc?
My idea is that the TestWebClient proc has a timer and from the timer call one by one a list of pages, parse it and fill the table.
Is there any way to do it?

Thanks
Alberto

It sounds to me like your calling proc should just have a web client class inside itself rather than calling off to another (synchronous) procedure.
