libURLSetStatusCallback: is there a simpler way?
I am getting errors with fetching data from a web server. The symptoms are: On occassion put url someURL in someXML return empty - that is someXML is empty. This happens when I click a couple of times on different items in the GUI in succession resuling in an error. I think though it is hard to debug, that this is because I am using load and mixing these calls with blocking call like the above when I want to get the data now. I am sure I read somewhere in the docs that multiple calls to the same URL can cause problems - is this right ??? In which case I should do a check with urlstatus(someURL) before calling the url? URLStaus? Well if this is the cause of the problem I could not fix it - as AFAIK urlstatus(someURL) only allows you to check the status of a url you know. In my case the previous url would be different from the one I am about to call - that is the script is about to check: www.mydomain/new.cgi and I have a number of load url http://www.mydomain/someimage.png; in progress. My guess is that because they share the same domain - the call to the cgi is returning empty - but that I cannot check the urlstatus before the call to the cgi as the urlstatus of new.cgi is empty and without tracking all the load calls in my script there is no way to find out how many urls are currenty loading but no finished loading - this is surely a deficiency of the urlstatus function? The hard way? Before embarking on this I thought I would check in to see if there is an easier way... but this is what I am thinking of doing... If I set libURLSetStatusCallback then I could effectively log all calls to urls that are in the process of loading but not in the cache yet. That is the following status commands would be (effectively) sent back from the server: queued: on hold until a previous request to the same site is completed contacted: the site has been contacted but no data has been sent or received yet requested: the URL has been requested And I could then store the urls of the pending urls yet to be cached by the load function? The easy way? It would seem there must be an easier way? Am I right about the source of the error? The only other way I can think of doing this is simply not to mix load and get url... from the same server. If I used another load if would be place in th cue. However then I loose my ability to prioritize calls to certain urls and all 500 thumbnails would have to load before a user click shows the full image... ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution
libURLSetStatusCallback
Dave, Thanks that works great. I'm still not understanding how the libUrlSetStatusCallback works. I've been reading the docs and I keep getting an error with the following test code: libURLSetStatusCallback myProgress,the long ID of me go stack URL http://www.x12help.com/mystack.rev; in a new window put myProgress into fld tester I have a button that is executing the code above and an empty field called tester. From what I've read I think the messages is going into MyProgress which I think I should be able to put out to a field or progress bar. I keep getting the error below. I'd appreciate any help I could get.

Also can you combine the Go Stack URL with the URLStatus and feed it to a progrress bar? You won't be able to use urlStatus, but you can use libUrlSetStatusCallback to track the progress. As for checking errors, it is probably easier to check the result. go stack url myUrl put the result into tRes if tRes is not empty then answer tRes end if Cheers Dave ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution

RE: libURLSetStatusCallback
Dave, Again that worked great. I'm going to try to feed it into a progress bar next.
