I can Know how many records are on xbrowse ?
I explain

I would like to activate the arrows for moving the records (up and down) only when the records are greater than the normal number displayed in the xbrowse table

oBrw:nLen

But in case of DBF, please see

I want to have the exact number of pages displayed with the dimensions of the xbrowse and I need this to activate my buttons which you can see in the right corner under the xbrowse
to activate my buttons I make

Code: Select all  Expand view

....
:CreateFromCode()
 END
lArrows:= IIF( oBrw:nDataRows<oBrw:nLen,.t.,.f.)


 

but it not run because I have 0 and -4

how I can resolve it ?

oBrw:nLen and oBrw:nDataRows get their values after the first Refresh/paint of the browse.
Also oBrw:nDataRows changes when browse is resized.

Code: Select all  Expand view

DEFINE BUTTON/BTNBMP ..... (arrows)  ... WHEN ( oBrw:nDataRows >= oBrw:nLen )

would work

Not%20working

I made

Code: Select all  Expand view

@  oBrw:nbottom+2, oBrw:nWidth-86 BTNBMP    aBtn[ 5 ]   SIZE 30, 25 PIXEL OF oDlg FLAT GDIP NOROUND  ; //
        RESOURCE "GRID_BOTTOM", "", hBmp, "" ;
     ACTION  oBrw:KeyDown(VK_DOWN, 0)  TOOLTIP "avanti"  WHEN (  oBrw:nDataRows >= oBrw:nLen   )
     @  oBrw:nbottom+2, oBrw:nWidth-56 BTNBMP    aBtn[ 6 ]   SIZE 30, 25 PIXEL OF oDlg FLAT GDIP NOROUND  ; //
        RESOURCE "GRID_TOP", "", hBmp1, "" ;
     ACTION oBrw:KeyDown(VK_UP, 0)   TOOLTIP "indietro" WHEN ( oBrw:nDataRows >= oBrw:nLen  )

INIT

perhaps I resolved with WHEN ( oBrw:nDataRows < oDbf:OrdKeyCount() )

init


after search

oDbf:OrdKeyCount() )

This works only for oDbf.
Using oBrw:nLen or oBrw:KeyCount() works for all datasources.

ok but the button are not refreshed , only when I move the mouse into obrw

for a sample
WHEN ( oBrw:nDataRows <= oBrw:nLen ) not work
WHEN ( oBrw:nDataRows >= oBrw:nLen ) not work


oBrw:nDataRows <= oBrw:nLen - Not working



oBrw:nDataRows >= oBrw:nLen Here it works but in reverse

any solution please ?

the problem is when I make a search for a sample "frank" ( on First) ndatarow is 3 and also obrw:nlen is 3

I tried to inser a variable nTotalrecords at init

oDbf:= TCustomer():New()
oDbf:setorder(1)
oDbf:Gotop()
nTotalRecords:= oDbf:OrdKeyCount()


and the on each button

WHEN ( nTotalRecords > oBrw:nDataRows ) but it's wrong also
