Different behaviour from VO to X#

Hi to all, i am transporting a big VO APP to X#.
i found an different behaviour from VO to X# about DATAWINDOW.
This code in VO open the window on shell, in X# not:
oWnd := Wnd_Acquisisci{SELF,,,Arr}
oWnd:Show()
SELF is a datawindow owner. Both are datawindow.
In X#, see image 1, the window is mixed with it’s owner.
Same code in VO, i have clicked on button “PDF ed Immagini”, see image 2
Any solution? Or i must change my code?
Bye

other different behavior:
I have to create a DBF from Array list. This array list come from a query.
In this query for join effect i have duplicate names like:
abi
abi
abicr
abiweb
accisa
acronimo
2 times abi, In VO this was working, in X# i got an error.
Clear that is an error but in VO code was working. I am currently porting from VO to X# and I don't know how many times in my code I have this case.
How can I fix it? How do you outclass the various DBCreates from the rdd ? In this case I would handle them myself.
Thanks a lot Alessandro

Sorry this is a different behavior from SQL return from VO and X#.
Thanks

Alessando,
I just tried this in VO and it also complains about a duplicate field name:
Code: Select all
FUNCTION Start( )
LOCAL aStruct AS ARRAY
aStruct := {{"ABC","C",10,0},{"ABC","C",10,0}}
DBCREATE("test",aStruct,"DBFNTX") // Error:
DBUSEAREA(TRUE,"DBFNTX","test")
? FieldName(1)
? FieldName(2)
DBCLOSEAREA()
WAIT
RETURN NIL
Error message in VO
Code: Select all
Error message:
--------------
Error Code: 1 [ ARGUMENT ERROR ]
Subsystem: DBFNTX
Error Subcode: 1037 (Field name already exists)
Function: DBCREATE
Argument: ABC
If you ignore the error in VO then the code continues but the file is NOT created.
RETURN NIL

Hi Robert,
sorry, i didn't realize there was a difference on calculating the DBStruct from SQL. I wrote a post about it right away, see above.
Thank you

Hi Alessandro,
di you are sure that you are not changing something in your window subclass?
In VO, if you are using a datawindow a another datawindows owner, the second becomes a subdatawindow of the first one. This is a standard behavior in VO (and it fouled me several times).
I suspect that you are checking somewhere in your code if the owner is a datawindow, and then use the owner of this datawindow.
