LISTBOX ALIAS

[Otto]

I have a listbox where I show the data.
I close the database and then I send the dbf-file back to the server.

In case that something goes wrong the user should return to the previous status.

select rechnung
use

oLbxRG:lCloseArea() // if I use lCloseArea the msginfo is ok otherwise I get an error

But then I find no way how to "oLbxRG:lOpenArea()" - how to rebind the oLbxRg again

lret := MEMOWRIT2(cSrc, cDSt )

lret := .f. //procl for testing a network error

if lret = .f.

Msginfo1 ( "N e t z w e r k f e h l e r" )


USE ( CurDir() + "\RECHNUNG" ) VIA "DBFCDX" NEW ALIAS RECHNUNG
oLbxRG:cAlias := "RECHNUNG"

endif


Best regards,
Otto

Otto,

Class TWBrowse Method lCloseArea() calls DbCloseArea(), so after calling it you may need to USE the DBF again if you need to manage it again

[Otto]

Hello Antonio,
I tried to do this but with no result:

if lret = .f.
USE ( CurDir() + "\RECHNUNG" ) VIA "DBFCDX" NEW ALIAS RECHNUNG
oLbxRG:cAlias := "RECHNUNG"
oLbxRG:show()
oLbxRG:gotop()
oLbxRG:refresh()
endif

Best regards,
Otto

Otto,

Why do you close the DBF and try to open it again from the same browse ?

[Otto]

Antonio,
doesn't PPC open the dbf-exclusivly?
I will check if I can copy a opened dbf back to the server.
Best regards,
Otto

Otto,

> doesn't PPC open the dbf-exclusivly?

I have not checked it myself

[Otto]

Antonio,
It I try to copy the opened dbf i get a dbf on the server with 0 byte.
Best regards,
Otto

Otto,

Have you tried to copy it before USE ing it ?

How do you copy it ? What source code do you use ?

[Otto]

Antonio,
If the file is not opend all is working.
This is the code I use:

Otto,

have you tried to USE the DBF in shared mode ?

[Otto]

Antonio,
thank you. SHARED works. But I am uncertain if SHARED is ready for use with PPC.
There are some posts in this forum which report of problems.
Would you suggest to use it?
Best regards,
Otto

[Antonio Linares]

Otto,

The FWPPC build that we published in march this year it is based on march Harbour and imo shared should work fine.

We were using a much more older Harbour previously so hence the shared complains. Anyhow, you tests will have the final word

[Otto]

Antonio,
thank you.
I shall install the new version of PPC and do more tests.
Best regards,
Otto

Shared mode works OK with fwppc, my app uses it since quite a while

PS : i am using an old version of fwppc
