total in xbrowse

[nageswaragunupudi]

Again xbrowse,
I would like to put a value (total column 3 / total colum 5) to the bottom of column "kgtota" an not the total of "kgtota"
Thanks

Code: Select all  Expand view

oBrw:oCol( 3 ):nFooterType := AGGR_TOTAL
oBrw:oCol( 5 ):nFooterType := AGGR_TOTAL
oBrw:oCol( 4 ):bFooter  := { || oBrw:oCol( 3 ):nTotal / oBrw:oCol( 5 ):nTotal }

can you help me?

You have to specify the DATASOURCE in the XBROWSE command.
You did not specify the alias "utile2" as datasource in the command. That is the problem

Code: Select all  Expand view

@ 10,10 XBROWSE oBrw SIZE -10,-30 PIXEL OF oDlg ;
            DATASOURCE "utile2" FOOTERS LINES CELL ;
 

Explanation:
When the line oBrw:MakeTotals() is executed, XBrowse should know from where to read the data and total. When you did not inform xbrowse the datasource, it fails.

CAUTION:
Please NEVER forget to specify the datasource while creating xbrowse. The datasouce can be an array, alias, object, etc.

Note:
Though you can create columns by using ADD command, I strongly recommend creating the columns with COLUMNS command inside the main XBROWSE command.
That has many advantages you will realise as you go.

Good very good, i'll try.

[damianodec]

Yes, but I want restrict utile2.dbf using ordscope() function. which command can I use with cAlias in xbrowse, LOCATE, SET FILTER?

[nageswaragunupudi]

You can use ordscope() or setfilter() as you like. Before or during xbrowse.

Explain me, if I want to use combining two .dbf in xbrowse, how can I do?

Explain me, if I want to use combining two .dbf in xbrowse, how can I do?

You probably mean when a dbf is set relation to another.
Assume that the customer.dbf is related to states.dbf in the fwh\samples folder/

@ 0,0 XBROWSE oBrw OF oWnd DATASOURCE "CUSTOMER" ;
COLUMNS "First", "City", "State", "STATES->Name" ;
HEADERS nil, nil, nil, "StateName" .......... <remaining clauses>

[damianodec]

Ok, if field states->nane is numeric, can I to get total on foot?

[nageswaragunupudi]

yes

Thank you!!!
