Hello,

I just updated to Revolution Studio 4.00 and Snow Leopard 10.6.2.
With this brand new Revolution Studio version, I made an update of one of my "good old" standalone freeware appl and I received a strange bug report: if the session's user has no administrator rights, the standalone only displays a white rectangle (only main card edges are visible) when launched on OS 10.6.2.
As usual, I compiled the standalone with "remove all profiles on objects" option checked and for Mac OS X Universal.

I'm not familiar with these administrator rights: I use a Mac with a single accout/user so I don't know what to do.
Can anyone tell me how could I manage this? Is it a bug, or maybe I made something wrong with this new Revolution Studio version? I never encountered this kind of problem with older versions.

Thanks for your help.

Hi Zax,

do you write something to disk "on openstack" or "on preopenstack"?

No, I only read settings from a xml file with "get revCreateXMLTreeFromFile(fichierPrefs,false,true,false)" on openstack.

Hi Zax,

hmm, it works on other machines, right?

You could use a "try" structure and show a dialog on error like this:
...

Code: Select all

try
 get revCreateXMLTreeFromFile(fichierPrefs,false,true,false)
## In case something does not work, the error will be "caught" in this variable "tError" and you can display it:
catch tError
  anser "Error:" & CR & tError
end try
...

Maybe this will give you a hint on what's going wrong.

Best

Klaus

Thanks Klaus, I'll try this soon and keep you informed here.

Some news:
It seems the reported bug was due to a buggy Mac account but, to be sure, can you tell if there is a difference between the "try - catch" method and the old hypercard method I use to use:

Code: Select all

get revCreateXMLTreeFromFile(xmlFile,false,true,false)
if word 1 of it is not "xmlerr" then -- or if the result is empty then
...ok, do some stuff
else
... problem
end if

Hi Zax,

sure this also works fine in this case!
The "try" approach is more generic and will work with any error in any script.

Have a nice weekend!

Best

OK, I understand.
The "try-catch" generic method seems better as the syntax is always the same.

Thank you Klaus
