Please Karinha,
For some time now, dear sir, you have been writing messages even if you have not been asked for anything, and even with other topics, if you read my post carefully, I was asking for a specific thing in particular

1) I not have Netuse
2) I made a test for dbf, tdatabase and tdata
3) I asked to try the test of Tdata, do you have the classs Tdata of James Bott ?

you have remmed these lines

// cSortOrder ??
// @ 20, 280 COMBOBOX oBrw:oSortCbx VAR oBrw:cSortOrder;
// SIZE 200, 400 PIXEL OF oDlg HEIGHTGET 20 STYLE CBS_DROPDOWN

I see that you have not understood my problem, my problem is in that combobox please see fwh\samples\xbsortcb.prg to see the original Nages sample

[karinha]

Sorry, my version doesn't have: fwh\samples\xbsortcb.prg

Regards.

When I created the application for the beach, in December 2020
james corrected the definitions for opening the archives by creating a class called Tincremental which was only used to add a counter.

In these definitions james omits the "DBFCDX" driver because perhaps with Tdata it was not needed or he takes them automatically.

Code: Select all | Expand

CLASS TTCategorie from TXAuto
   METHOD New()
ENDCLASS

METHOD New( lShared ) CLASS TTCategorie
   Default lShared := .t.
   ::super:New(,::cPath + "Categorie" ,, lShared)
   if ::use()
      ::setOrder(1)
      ::gotop()
   endif
RETURN Self
 

Just yesterday reviewing the code I realized that the definition created by James calls the New method of Tdatabase which,

Code: Select all | Expand

 ::super:New(,::cPath + "Categorie" ,, lShared)

however, wants the definition of the "DBFCDX" driver,

Code: Select all | Expand

 ::super:New(,::cPath + "Categorie" ,"DBFCDX", lShared

in fact adding this parameter then the test works wonders.

[James Bott]

You don't ever want to add the database driver in the database class's New() method--you should define the default driver at the beginning of the program. This way all routines in the app use the same driver and if you ever want to change the driver you only have to change it in one place.

The only exception to this rule (that I can think of) is if you needed to use a file and index from a different app that is using a different driver. Then you still use a default driver for the current app but specify a different driver for a special routine. This would extremely rare I think--I have never needed to do this.

James,
