Status for read (load) Re: Re: url restrictions

The example url could be: http://maps.dnr.state.mn.us/cgi- bin/mapserv36?map=/usr/local/www/docs/mapserver_demos/tests36/aut o_rotate/test.map&mode=map&map_test_class_label_position=CC&map_t est_class_label_angle=0 Thanks to Gabriele, the load works for it! Sorrry ... I am just starting to go in the structure of Docs... ;-) The next question is how to get status/progress for loading process of the image. I would like to display them for user in an statuss bar. I searched scripts for and find that read-thru could be used. Is this the right way? The docs of read-thru are quite limited (no examples) - dificult for dummies. ;-) Anyway - I tried some variants, but all excepting with to refinement returns error: .... 0.597625 0.597625 ** Access Error: Cannot open /c/progz/rebol/public/maps.dnr.state.mn.us/cgi-bin/mapserv3 6?map=/ ** Near: make-dir/deep loc-path And again this way I would not prefer if it is possible, because it requires to write to disk. Am I going to right direction? brgds Janeks On 17 Jan 2005 at 19:20, Anton Rolls wrote:

Hi Janeks Anton's script referred to in the ML archive message thread seems to have moved. As an alternative, there are a number of examples of progress bars in the script library: www.rebol.org script library home search for progress Regards Peter

Is it so, that request-download any way makes an temp file? brgds Janeks On 18 Jan 2005 at 21:34, sags-apollo.lv wrote: >>>>myImg: request-download

Rebol's PATH-THRU (used eventually by request-download), does not do anything about illegal filenames (ie. containing the character "?". So when request-download goes to save the file, it fails. I suggest you either specify your own location for the file like this: request-download/to url %image.gif view layout [image %image.gif] which I think you probably want to do anyway (placing your own map/ directory somewhere nice), or you need to make your own version of path-thru which creates a good filename even when given "bad" characters like "?", and make a modified version of request-download which uses that. I was actually thinking about this recently - it annoys me once every while that I can't cache rebol.org scripts easily ( just by the idiom READ-THRU url). Doing a good job of fixing it is a large task. You need to find out what the allowed characters are for each platform supported by rebol, then munge the filenames in such a way that there are not likely to be collisions, etc.. Anton.

O'k than that is a minor problem. Anyway for this case the fetched image file will not be lage, so going throught saved file in every case wiil not cause significant time/performance loss. brgds Janeks On 19 Jan 2005 at 18:51, Anton Rolls wrote:
