Sample with xBrowse, Fastedit and recordset

[Armando]

Dear friends:

I'm looking for a sample using xBrowse with cell edit and recordset.
I have looked for in the forum without success.

Thanks a lot for your sample

Consider this code .. it does a bit more than you asked .. notice FASTEDIT and AEVAL( oBrw:aCols, { |o| o:nEditType := EDIT_GET } )

Code: Select all  Expand view

Rick:

Thanks a lot for your sample, I will try it.

There are samples in the fwh\samples folder. In particular testxbr3.prg gives samples for different kinds of datasources like RDD, Array, RecSet and Trees.

Here is a very simple sample for ADO RecordSet

Code: Select all  Expand view

#include "FiveWin.Ch"
#include "xbrowse.ch"

//----------------------------------------------------------------------------//

function Main()

   local oRs, oDlg, oBrw, oFont

   XBrNumFormat( 'E', .t. )

   oRs   := OpenRecordSet()
   if oRs == nil
      ? 'Open fail'
      QUIT
   endif

   DEFINE FONT oFont NAME 'TAHOMA' SIZE 0,-14
   DEFINE DIALOG oDlg SIZE 700,400 PIXEL FONT oFont

   @ 10,10 XBROWSE oBrw SIZE -10,-10 PIXEL OF oDlg ;
      COLUMNS 'First', 'City', 'State', 'Salary' ;
      DATASOURCE oRs ;
      AUTOSORT FASTEDIT CELL LINES NOBORDER

   WITH OBJECT oBrw
      :nEditTypes    := EDIT_GET
      :nStretchCol   := 1
      //
      :CreateFromCode()
   END

   ACTIVATE DIALOG oDlg CENTERED
   RELEASE FONT oFont

return nil

//----------------------------------------------------------------------------//

static function OpenRecordset()

   local oCn, cStr, oRs

   cStr     :=  "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + ;
                "c:\fwh\samples\xbrtest.mdb;User Id=admin;Password=;"

   if ( oCn := FW_OpenAdoConnection( cStr ) ) != nil
      oRs   := FW_OpenRecordSet( oCn, "CUSTOMER" )
   endif

return oRs

//----------------------------------------------------------------------------//
 

XBrowse automatically takes care of formatting, editing and saving to the recordset.

Mr. Rao:

Thank your for your advise and excelent sample.
