VO Application ported to X#

Juraj · Post by **Juraj** » Wed Jul 26, 2017 6:50 am

Hi All,
I have old project created with CaVo 2.6. Can be imported into X#? If yes, how to proceed?

Hi Juraj,

theoretically it should work the same manner as with a 2.8 application because the xPorter reads AEFs.

But the compiler could give a lot more errors than with a 2.8 application because the 2.7 and 2.8 compilers introduced a lot more checks, and some things that gave no errors in 2.5/2.6 resulted in warnings in later versions, like methods without return statement and some assignments between signed/unsigned numeric variables.

If you have no Vulcan license, you could try to use the Vulcan demo version and try to move your application to X#.

Another possibility would be to acquire the update to VO 2.8 and move your application there. That would also give your a better starting point for the VO class libraries (that cannot be delivered with X# because of license issues).
Anyway, a migration to VO 2.6 to 2.8 would boost your productivity for the time you are working with VO.
But of course it depends how many code you have to move and how important this code is.

Unfortunately I cannot say anything precise because I have never worked with VO 2.6 (moved directly from 2.5 to 2.7 and then to 2.8 ).

Hi Juraj

the Porter can not read .aefs from previous versions to vo 2.8.
That means you have to Import your 2.6 / 2.7 aef to 2.8 and Export it again.

Markus,
where did you take that from?
VN-Transporter had this limitation (reading projects), but i can't remember the aef-format having changed between Vo versions...

Hi Karl, hi Markus,

I have now dowloaded a 2.5 AEF from fabtoys.net and tried to read it with xPorter, and it could transport it without issues.

The AEF format has changed between versions, but the library used by the xPorter should be able to read all formats.

Hi all,
Where can I download the version XPorter for VO? My current version work only with Vulcan files.

Hi Karl

if I try to Import a 2.7 aef the Transporter gives an error message. If I Import this 2.7 aef into 2.8 and Export it again, then the Transporter works as expected.

Hi Juraj,

VO-xPorter should be installed in the VOXporter subdirectory of your X# directory.
It is a separate application.

Hi Markus,

strange.... I have now downloaded the 2.7 version of FabZip and tried xPorter on it, and it worked. Maybe your AEF is damaged and the import/export procedure fixes it?

Wolfgang

Juraj · Post by **Juraj** » Wed Jul 26, 2017 8:19 am

Hi Wolfgang,

Thank you for your answers, helped me a lot. I porting my AEF file to X# successfully
and I'm going to remove errors from my code.The error is the most repeated:

error XS9002: Parser: mismatched input '(' expection EOS

my code is:

lOk:=oZoz:CreateOrder("ZOZICO",WorkDir()+"ZOZICO","ICO",{||_field->ICO})

oZoz is DbServer

or:
infobox{SELF,"Indexovanie zoznamu..","Nepodarilo sa preindexovat zoznam firiem."}:Show()
or:
FErase(String2Psz(WorkDir()+"A1.DBF"))
