| Janeks 28-Sep-2006 [1781] | Ups - finaly I got what was wrong - if you used in the past larger verion numbers - it is not good idea to reset them back to smaller. Soory for disturbance! |
| Gregg 28-Sep-2006 [1782x2] | You mean the version in your script header? |
Or the version in your HTML page? | |
| Louis 12-Oct-2006 [1784x2] | I get the following error message: ** Syntax Error: Script is missing a REBOL header ** Where: do-thru ** Near: do/args url arg >> but there is a valid rebol header. What could be causing this? |
Here is the script that is being called: REBOL [] print "What?" ask "Continue?" | |
| Allen 12-Oct-2006 [1786] | How is it being called? Why is it going via do-thru?, is the script (cached by do-thru) exactly the same as the remote one? |
| Louis 12-Oct-2006 [1787x5] | Here is the script that calls it: <HTML><HEAD><TITLE>Test - REBOL Plugin Demo</TITLE> <script language='javascript' src='http://127.0.0.1:1026/js.cgi?pca&r=28703'></script> </HEAD> <CENTER> <H1>Test - REBOL Plugin Demo</H1> <OBJECT ID="REBOL_IE" CLASSID="CLSID:9DDFB297-9ED8-421d-B2AC-372A0F36E6C5" CODEBASE="http://www.rebol.com/plugin/rebolb7.cab#Version=1,0,0,0" WIDTH="360" HEIGHT="442" BORDER="1" ALT="REBOL/Plugin"> <PARAM NAME="LaunchURL" value="http://localhost/slideshow/test.r"> <PARAM NAME="bgcolor" value="#ffffff"> <PARAM NAME="version" value="1.0.2"> </OBJECT></CENTER></BODY></HTML> <script language='javascript'>postamble();</script> |
I'm running Cheyenne so I can test the plug in on my local computer. | |
I don't know about the caching question. How do I check that? | |
Sorry for the delays in answering. I'm paying by the minute, so have to log off while waiting for people to answer. | |
I just deleted all off-line content cached by Internet Explorer. The problem remains. | |
| Anton 12-Oct-2006 [1792] | You would examine the cached file using: editor path-thru http://localhost/slideshow/test.r But let us see what this returns: print read http://localhost/slideshow/test.r |
| Louis 12-Oct-2006 [1793x2] | editor path-thru http://localhost/slideshow/test.r brings up an erro message saying the file cannot be read (perhaps because it doesn't exist?) print read http://localhost/slideshow/test.rreturns >> print read http://localhost/slideshow/test.r connecting to: localhost What? Continue? >> >> print read http://localhost/slideshow/test.r connecting to: localhost What? Continue? >>>> print read http://localhost/slideshow/test.r connecting to: localhost What? Continue? >>>> print read http://localhost/slideshow/test.r connecting to: localhost What? Continue? >> |
Whoops! a few repeats there; I pasted too many times. | |
| Anton 12-Oct-2006 [1795x3] | exists? path-thru http://.... |
probe info? path-thru http://... | |
But that "What? Continue?" doesn't look right to me :) Try 127.0.0.1 instead of localhost and see if that makes a difference. | |
| Louis 12-Oct-2006 [1798x2] | >> exists? path-thru http://localhost/slideshow/test.r == false >> probe info? http://localhost/slideshow/test.r connecting to: localhost make object! [ size: 15 date: none type: 'file ] >> |
127.0.0.1 makes no difference. | |
| Anton 12-Oct-2006 [1800] | Right, well, it looks like it is not a plugin issue, but a url or webserver issue. |
| Louis 12-Oct-2006 [1801] | OK, thanks. |
| Anton 12-Oct-2006 [1802] | Have you tried opening that url in a browser ? |
| Louis 12-Oct-2006 [1803] | Yes, that is when I get the error message. First the web page displays with a box containing the message REBOL/Plugin 2.6.6.3.1, then a REBOL/ViewDLL window pops up with the error message. |
| Anton 12-Oct-2006 [1804x2] | No I mean directly opening that url in a browser, eg: browse http://localhost/slideshow/test.r |
It seems to me that reading this url is not getting the rebol script that you are expecting, so of course the plugin is going to fail when you direct it to it. | |
| Anton 13-Oct-2006 [1806x3] | I expected your console session to look like this: >> print read http://localhost/slideshow/test.r connecting to: localhost REBOL [] print "What?" ask "Continue?" >> and not this: >> print read http://localhost/slideshow/test.r connecting to: localhost What? Continue? >> |
You're using Cheyenne as the web server, so probably Cheyenne is doing the rebol script as it would to support Rebol Server Pages. | |
You should look into Cheyenne's options regarding Rebol Server Pages and see it there's a way to disable it for certain scripts. | |
| Louis 13-Oct-2006 [1809x2] | Anton said: No I mean directly opening that url in a browser, eg: browse http://localhost/slideshow/test.r OK, that works! Would you believe it? I was doing the same thing wrong that I did earlier. I misunderstood the reason behind it. Anyway this does not appear to have been caused by Cheyenne, but merely by my ignorance. Anton, thanks again for your help! |
No, I spoke too soon. http://localhost/slideshow/test.ris the plug in script. http://localhost/slideshow/SlideShow2.htmlstill gives the error. | |
| Anton 13-Oct-2006 [1811] | What does browse http://localhost/slideshow/test.r give you ? What is shown in the browser ? |
| Louis 13-Oct-2006 [1812] | What? Continue? |
| Dockimbel 13-Oct-2006 [1813x5] | .r files are treated as CGI script by default in Cheyenne. To change that, you have to edit the httpd.cfg file and change the following line : |
bind-extern CGI to [ .cgi .r ] | |
to | |
bind-extern CGI to [.cgi] | |
So .r files will be treated as static ressources. | |
| Graham 13-Oct-2006 [1818] | so change the extension ? |
| Louis 13-Oct-2006 [1819x12] | Doc, thanks. My test script now runs. |
However, when I try to run my slideshow script, the plugin is unable to load the data file. | |
Ok, I put the data into the script as a block of blocks, but now the plugin cannot load the image files. Am I at a deadend here? or is there still a way to make this work? | |
Simplicity is turning complicated. | |
If I use to-binary to convert an image to a binary string that can be stored in the View script, how can I then display it? image to-image binary-string doesn't work. | |
I remember seeing a script that did this once, but I don't remember which script it was. One of Carl's perhaps. | |
build-pack.r from the library seems to be just what I need. | |
No, I don't think build-pack.r will work either, as it would have to download all the data with the script before the slideshow would start. | |
I have one other idea. | |
Sweet success! It now works perfectly running under Cheyenne on my local machine. Now for testing on a remote server. | |
Thank you Dockimbel! Cheyenne made this possible. | |
Thanks also to Anton, who always helps me through the difficult parts. | |
