Hi,
I wrote an email sender/receiver in IMAP (using cURL if anyone is curious). I parse the email received and decompose it into its different parts but when I try to show its body with "set the htmltext...", if the email has any img tags, it will very often crash or starts running forever. The reason is that Livecode doesn't give enough time to download the src and can't close properly the connexion. I can get read of the img and then it works but that's obviously not a super satisfying answer...
I still have to investigate to understand exatly the "mecanism" of htmltext before maybe reporting a bug but has anyone experienced somthing similar ? Any suggestions/solutions ?
Thanks !

Re: htmltext crashes because of images
The problem could also be in the image reference. Can you post an example of some htmltext that fails?

Re: htmltext crashes because of images
Thanks for the reply Jacque. Sorry for taking so long to answer back... I am trying to refine my test to understand what is going on.
First, you have to know that I have had this problem with many different email body in html form but that it doesn't happen every time (for one email). It seems to depend on the quality of the connection...
Also, the thing happens too when I reopen a card containing a field already set to htmltext.
When you ask for an example do you mean an actual html file that causes the problem ? If yes, I can't because my upload is rejected ("identifie as possible attack"). Otherwise, for the code itstelf, I simply do a
inside a command in a button.
But the whole program is pretty complex because its an OS interface for blind people, so there are constantly observations and changes of fields, properties and variable via the idle so the person can be informed.
Thanks again for your help !

Re: htmltext crashes because of images
I was mainly wondering if there was something unusual in the html, in either the image references or some other formatting. You could copy a short section of a text file that you know fails and paste it into a reply here.
But the real issue may be that the script is using the wrong property name. It should be "htmltext" rather than "html" .
Edit: I'd think it shouldn't crash because setting "the html" of a field should just create a custom property of the field rather than display the text. I wonder if "html" is an undocumented reserved word that sends the engine into an infinite loop. At any rate, a crash is always a bug so it should be reported.

Re: htmltext crashes because of images
Ok first of all, sorry for calling you Jacque.. Jacqueline. Secondly, my mistake, I wrote too fast : the code is indeed and not the html...
Also, here is an example of email body in html format that causes problems :

Re: htmltext crashes because of images
Hi godot,
just made a quick test:
Where field 1 contains the html source you posted here.
No images in the field, but also no crashes!
OS X 10.11.1 and LC 7.1.1RC3

Re: htmltext crashes because of images
LC 6.7.6 is getting the images.
But watch out, they end up at the top not down the left side.
