Illegal characters in path message during file upload

[mobybrick]

Hi,

 

Using HAP+ 8.6.

 

When using MyFiles, users can browse all paths successfully. If, however, a user tries to upload to a remote path that contains an ampersand in the remote pathname (e.g. "Art & Design") then the upload fails with the message below. Downloads are not affected - it appears to be upload operations only.

 

Thanks,

Moby.

Anyone? This appears to be a reproduceable problem.

Sorry wrong post. I will investigate a fix for this.

 

Which upload agent are you using? HTML5 or the old HTML uploader (1 upload box or 5)?

Ok, I think I've found the issue will be fixed in the next release, hopefully later today.

Hi Nick,

 

Sorry to report, but this is still happening. IE9, so HTML uploader. With the 8.7 code. Note how the apersand is replaced to |26 in the browser bar.

 

The upload path was ../testhap/myfiles/#G\2012-2013\DEPARTMENTS - FACULTIES\DESIGN FACULTY\Design |26 Technology\Food\New folder

Can you try the attached dll and report if it fixes it

[mac_shinobi]

@nickbro - appologies in advance if this is of no relevance or help at all, if it is not then can a mod please delete this comment if required

 

On the "Security" tab in the "Internet Properties" control panel there is a button to customise the security level for whichever zone is selected there. Clicking that gives you another dialogue box with a list of options. Roughly halfway down that list there is an option for "Include local directory path when uploading files to a server". If that's disabled for the relevant zone (whatever zone IE says it's using when you're using your app), try enabling it.

 

Just wondering if this helps at all ( obviously depends on version of IE ) Think this setting is for IE 8, not sure if this setting exists in IE 9 or other versions of IE

 

Just a shot in the dark / thought that may or may not help

[mobybrick]

Don't believe the local path is anything to do with it - the local path is C:\

Hi Nick,

 

Tried the DLL - thanks - but no joy:

Ok, I'll have to have another look when I get home tonight, see if I can get some more information outputted when you go on that page

[mobybrick]

Hi Nick,

 

I've never been able to build HAP at home, but if I build a quick test app then any call to Path.Combine will cause an exception if " |26 " is in the string. Why |26 is/may be in the string I don't know apart from the fact it obviously takes the place of the ampersand.

 

The line

string path = Server.UrlDecode(Request.QueryString["path"].Remove(0, 1).Replace('^', '&'));

 

could be replaced by

string path = Server.UrlDecode(Request.QueryString["path"].Remove(0, 1).Replace('^', '&').Replace("|26", "&&");

 

but I don't know what other problems that might introduce. Nor why one should have to fudge around it anyway! Anyway, it case it helps.... thanks for looking at this...

 

Regards

Moby.

[nickbro]

Doh, I'd added it to the load function but not the upload button function

 

the script is

 

string path = Server.UrlDecode(Request.QueryString["path"].Remove(0, 1).Replace('^', '&').Replace("|", "%"));

 

Can you try this one next, otherwise I'll have to go back to the drawing board and see what else I've missed

[mobybrick]

Hi Nick,

 

I'll try this tomorrow as soon as I get a chance

 

Thanks,

Moby

[nickbro]

thanks let me know, it should work as it's the same code as the html5 upload script

[mobybrick]

Hi Nick,

 

Sorry for the delay in responding - couldn't try anything yesterday due to a project.

 

The last web.dll fix does indeed correct the problem with the upload issue. Thanks again!
