SetMultiSelectCol() on line

[Silvio.Falconi]

I have an xbrowse created with an array without the :SetMultiSelectCol()
and I have the ability to display a menupopup like this

MENU oMenu POPUP
if oBrw:IsSelectedRow()
MENUITEM "Deselect the current row" action DeSelect_One_array(oBrw)
MENUITEM "Deselect everything" action oBrw:SelectRow( 0 )
MENUITEM "Prints the selected lines" action PrintBrowse(oParent:cCaption,oBrw,oDbf)
MENUITEM "Export the selected rows" action ExportToExcel(oBrw )
else //
MENUITEM "Select the current row" action oBrw:SelectRow( 2 )
MENUITEM "select all" action oBrw:SelectRow( 4 )
MENUITEM "Print " action NIL //PrintBrowse(oParent:cCaption,oBrw,oDbf)
....


Before making the selection, I would like to check whether SetMultiSelectCol() is activated in the xbrowse and if it has not been activated, activate it on first column before the selection. Obviously, when no records are selected, SetMultiSelectCol() must disappear

how can I implement this?

Any solution ?

Dear Silvio,

Could you please provide a small and self contained PRG example ?

thanks!

Dear Silvio,

Have you reviewed samples\xbmulsel.prg ?

[Silvio.Falconi]

Dear Silvio,

Have you reviewed samples\xbmulsel.prg ?

yes allready saw it

compile this test without :SetMultiSelectCol() you'll see this error

Error description: Error BASE/1005 No exported variable: LREADONLY
Args:
[ 1] = U
[ 2] = L .T.

Maybe I did not say it clear enough

I would like the procedure to check whether xbrowse has/does not have :SetMultiSelectCol()

if it does not have the :SetMultiSelectCol() the procedure must create the :SetMultiSelectCol() as the first column of the xbrowse and give the possibility to select the row

If there are no selected rows in the xbrowse the procedure must remove the :SetMultiSelectCol()

instead the test samples\xbmulsel.prg example already has the SetMultiSelectCol and the checkbox disables it but physically it is still in the xbrowse

I hope I was clear in my explanation
