Count xbrowse records

[wartiaga]

Hi, I have a xbrowse:

Lista40:cAlias := "ARQANO"

How I count records? I don't want the deleted ones to enter the sum.

Thanks!

perhaps

len(oBrw:aArrayData )

or

oBrw:nDataRows

With or without XBrowse, we need to know the number of records in a DBF which are not deleted.
There is no simple function for this.

Does not matter whether SET DELETED is ON or OFF:

Both LASTREC() and RECCOUNT() include deleted records also.
ORDKEYCOUNT() also does not exclude deleted records by itself, but honors filters, scopes and index expressions.

So,

1)

Code: Select all  Expand view

SET FILTER TO !DELETED()
? OrdKeyCount()

2)

Code: Select all  Expand view

INDEX ON RECNO() TAG RECS FOR !DELETED() // keep this index tag also
// then
? OrdKeyCount( "RECS" )

3)

Code: Select all  Expand view

INDEX ON RECNO() TAG DELS FOR DELETED() // kee this index tag also
? OrdKeyCount(0) - OrdKeyCount( "DELS" )

Nages,

is there a function in Xbrowse to calculate how many records are visible in xbrowse?

I explain to you:
at the bottom of the Xbrowse I want to insert two buttons to move the records and I want them to be activated only if the record count exceeds the actual display of the Xbrowse

Code: Select all  Expand view

@ 148, 320  BTNBMP aBtnBrow[1] ;
     RESOURCE "DWN_TBL", "", hBmp, "" ;
      SIZE 15, 13 PIXEL FLAT NOROUND GDIP WHEN lArrows  OF oDlg ;
      ACTION oBrw:KeyDown(VK_UP, 0)

 @ 148, 335 BTNBMP  BTNBMP aBtnBrow[2] ;
     RESOURCE "UP_TBL", "", hBmp1, "" ;
      SIZE 15, 13 PIXEL FLAT NOROUND GDIP WHEN lArrows OF oDlg ;
      ACTION oBrw:KeyDown(VK_DOWN, 0)

 

For example, if I have an Xbrowse in which 20 records are displayed at a time but there are more records in the archive (for example 50)
the lArrows must be true

len(oBrw:aArrayData )

oBrw:nDataRows

Thank you!

Mr Nages thank you! I solved it by adding the !deleted() in index
