Hi there dear LiveCoders,

I'm coding a tiny news application.
Actually, it's almost done.
Unfortunately, I cannot show the image of related news in its corresponding area.
set the filename of image "myImage" to myUrl doesn't work, naturally
Images are on the web and I don't want to download them into a temp directory.
And I can't use browser controls because there are hundreds of news.
I don't know how to deal hundreds of iOS controls, I don't want to either.
Is there a way to do this, like
Or do I have to download them first into a temp folder, then set their filenames to the local images?

Hi Ender,

set the filename of image "myImage" to myUrl
doesn't work, naturally

well, but that's the correct and official syntax!

According to the dictionary this should also work on iOS.
Did you try it? Maybe it takes while, but should work!

Yes, it works
It's taking too long but it loads all the images.
I've imagined that it can't load therefore freezes my app.
It waits on splash screen to load them.
Now, I have to think a workaround against this waiting issue.
Any quick idea?

By the way, thanks so much Klaus,

Hi Ender,

well, loading stuff from the net in the splash screen/appstart is a bad idea!

I would displasy a static image in the splash screen and then load the images AFTER the splash screen disappeared.
Maybe you could really "load" the images first, which is non blocking, and then set their filename to the files on disk
or to the cached url, where the latter is of course not persistent.

Maybe you could first check if you already downloaded one or more of the images before loading again.

Check "load" in the dictionary, you can define a "callback" message that is send when the download has finished.
Please try this and come back with specific questions.

Thanks, I'll try.
I'm also thinking a server-side solution.
A php code which will produce a 4kb thumbnail image of ~100 kb actual image,
right after when the client enters the actual image url in the app's admin panel on web.
The admin panel is only to enter the news' into database, btw.

Well, the image area of each news is 50px*50px.
There is no need to load actual big image, right?

I think your advice and my solution combined is gonna work
Thanks again...

Hi Ender,

yep, the rule of thumb is to have images on the net in the same size as they are displayed.
That is the most efficient way, even in the days of high-speed DSL

May I ask where you are from?
Your name sounds a bit turkish to me

Yes, I'm Turkish, I live in Istanbul;
und ich glaub' du bist Deutsch, richtig?
Twenty years ago I've studied Deutsch for 2 years, that's what's left ha ha
