I am using the webcustomcontrols plugin (in version 2.2 as it does not yet work in any newer versions) however under mavericks it is very intermittent so I am trying to detect if we is connected to a mavricks o/s or not. Don’t think this is possible but I need to call the Xojo file uploader if its not mavericks and wcc if it is. Anyone know if this is possible?
You could use Session.Header(“User-Agent”) to pull the user agent string like this:
dim s as string = Session.Header("User-Agent")
dim rx as new RegEx
rx.SearchPattern = "(?mi-Us)Mac OS X ([0-9_]*)"
dim rxOptions as RegExOptions = rx.Options
rxOptions.LineEndType = 4
dim match as RegExMatch = rx.Search( s )
if match<>nil and match.SubExpressionCount > 0 Then
dim vers as string = match.SubExpressionString(1).ReplaceAll("_",".")
End If
I’d do this in the Session.Open event so it only gets called once.
Remember: vers is a string because it could return “10.8.5”
(Special thanks to @Kem Tekinay for his RegExRx app which I used to generate this code 
)
Web Custom Controls does work with Xojo 2013r3.x. It’s only the jQueryFileUpload control that has a problem with r3 due to Feedback issue 29775, which has been fixed but has not yet shipped.
Dave - I have been unable to reproduce your issue using jQueryFileUpload with Xojo 2013r2. The test project you sent worked perfectly. I would love to help you with this but I’m going to need more information or a test project that more closely approximates what’s happening in your application. Please email me for further assistance.
