i want to shsw DELETED Record so i use

Code: Select all | Expand

    SET DELETED OFF
   BrowseDBF( cPath, cFile, cAlias, cRdd )
   SET DELETED ON

but when call

Code: Select all | Expand

   oBrwDBF:Delete( .T. ) // what is Parameter .T. for ?

i got a "YesNo Box" and after "Yes" Record disappear in XBROWSE ...

so how configure XBROWSE to "show" DELETED Record which i can RECALL

p.s. open DBF have no Index

[Jimmy]

hi,

did nobody have a Solution to "show" DELETED Record in XBROWSE

[nageswaragunupudi]

I am just starting my work.
Pls wait

[nageswaragunupudi]

what is Parameter .T. for ?

Syntax:

Code: Select all | Expand

oBrw:Delete( [lMessage] )

If the lMessage parameter is .T., a MsgeYesNo() box is displayed and only if the user selects "Yes", the Record is deleted()
Otherwise, the record is deleted without any message.

If SET DELETED IS ON, deleted records are not displayed and after deletion, the deleted record goes out sight.
If SET DELETED IS OFF, all deleted records appear and even after deletion, the record still appears.
We confirm this behavior.

If in your case, after deletion, the record disappears, Set Deleted might be ON at that time. We request you to recheck your program.

hi,

you Sample work

i saw these Line

Code: Select all | Expand

    COLUMNS "DELETED() AS DELETED","CODE","NAME" ;

   :RecSelShowRecNo()
   :Deleted:SetCheck(,.t.)

Sample need COLUMNS "DELETED() AS DELETED" ... but i don´t know Column as i don´t have "fix" DBF

i do use

Code: Select all | Expand

   COLUMNS ColsNumber( DBSTRUCT() ) ;

hm ... can i build a String of COLUMNS before create XBROWSE, will that work

--

i have add Msginfo(() before ACTIVATE

Code: Select all | Expand

   Msginfo(" DETELED IS " + If( Set(_SET_DELETED), "ON", "OFF" ) )

   ACTIVATE WINDOW oWnd ;
 

just to be sure that DELETED if OFF

but still i do not seen any DELETED Record in XBROWSE ...

Code: Select all | Expand

      @ nBhight,  2 XBROWSE oBrwDBF SIZE nWidth - 20, nHeight - 90 PIXEL OF oWnd ;
              DATASOURCE cAlias ;                 // ALIAS cAlias
              COLUMNS ColsNumber( DBSTRUCT() ) ;
              FONT oFontDefault ;
              COLOR BFcolor, BGcolor ;
              CELL LINES NOBORDER FASTEDIT AUTOCOLS AUTOSORT

      oBrwDBF:nStretchCol := STRETCHCOL_WIDEST

      oBrwDBF:lRecordSelector := .F.
      oBrwDBF:bChange := { || SayStatusDBF( oBrwDBF, oGet, @nVar ) }
      oBrwDBF:bOnSort := { || oBrwDBF:Refresh() }

      // oBrwDBF:bClrEdit     := { || { BFcolor, BGcolor } }
      oBrwDBF:bClrStd := { || { BFcolor, BGcolor } }
      // oBrwDBF:bClrSel      := { || { BFcolor, BGcolor } }
      oBrwDBF:bClrHeader := { || { BFcolor, BGcolor } }
      // oBrwDBF:bClrFooter   := { || { BFcolor, BGcolor } }
      // oBrwDBF:bClrSelFocus := { || { CLR_WHITE, GetSysColor( COLOR_MENUHILIGHT ) } }
      oBrwDBF:bClrGrad := bGradient

      // edit CELL
      // oBrwDBF:nEditTypes := EDIT_GET
      // override F2 CELL edit
      // oBrwDBF:lF2KeyToEdit := .T.

      * oBrwDBF:RecSelShowRecNo()
      * oBrwDBF:Deleted:SetCheck(,.t.) // COLUMNS "DELETED() AS DELETED",

      oBrwDBF:CreateFromCode()
 

what i´m doing wrong that DELETED Record are not show in XBROWSE

will try to make Sample

[Jimmy]

hi,

found a Solution for "me" , but not able to make a Sample

in my MAIN i have

Code: Select all | Expand

   SET DELETED ON

i have try this

Code: Select all | Expand

   USE (cDBF)
   SET DELETED OFF

so it was AFTER open DBF ...
this make the funny Effect that MsgInfo say "OFF" but DBF "react" like "ON"

now when change to

Code: Select all | Expand

   SET DELETED OFF 
   USE (cDBF)

it work

but as i say i can´t reproduce it in a small Sample

[nageswaragunupudi]

Whatever happens to your end, you should be able to reproduce with a sample.
Like whatever we said, we proved with a sample.

If you can please clarify my doubt, I am interested in knowing this:

In case of Clipper/Harbour, SET DELETED OFF/ON is a Global (application wide) setting, whereas in case of Dbase/FoxPro, this setting is a workarea wise setting.

That means, in this code:

Code: Select all | Expand

SELECT 1
SET DELETED OFF
SELECT 2
SET DELETED ON
SELECT 1
// now whatis the status?
// In Clipper/Harbour, it is ON
// In DBase/FoxPrro is OFF
// In Xbase++ ???
 

Can you kindly clarify if XBase++ is compatible with Dbase/FoxPro behavior or Clipper/Harbour behavior?

[Jimmy]

hi,

Xbase++ SET DELETED OFF/ON are Global (application wide) setting, even in Thread which have a other "Workspacelist"

i can send you hole Project as i´mm not able (yet) to build a Sample which same Effect.
it doesn´t matter in "this" Project as DUALGRID but for other Project i have to find out what is going on

[nageswaragunupudi]

Yes, please.
Though I am not sure if can understand.
