XBROWSE BUSQUEDA INCREMENTAL

[Luis]

Como estan :
Quisiera hacer búsqueda incremental encontré una solución en el foro pero cuando la aplico a mi programa no responde sale como caracteres extraños cuando digito y fuera de sitio en el GET y en el XBROWSE no sale nada. Alguna sugerencia?. Muchas Gracias.

Mr Luis

May I know which version of FWH you are using?
If you are using any recent version which has inbuilt incremental filter feautue of xbrowse, we can help using the inbuilt feature. This is extremely simple to use.

This sample shows how simple is it to implement incremental filters:

Code: Select all  Expand view

function incfilter

   local oDlg, oBrw, oFont

   USE CUSTOMER NEW VIA "DBFCDX"
   DEFINE FONT oFont NAME "TAHOMA" SIZE 0,-14
   DEFINE DIALOG oDlg SIZE 800,300 PIXEL FONT oFont
   @ 30,10 XBROWSE oBrw SIZE -10,-10 PIXEL OF oDlg DATASOURCE "CUSTOMER" ;
      COLUMNS "FIRST","LAST","CITY","STREET","SALARY" ;
      CELL LINES AUTOSORT NOBORDER

   WITH OBJECT oBrw
      :lIncrFilter      := .t.
      :lSeekWild        := .t.
      :cFilterFld       := "CITY"
      //
      :CreateFromCode()
   END

   @ 10,10 SAY oBrw:oSeek VAR oBrw:cSeek SIZE 100,10 PIXEL OF oDlg COLOR CLR_HRED,CLR_YELLOW

   ACTIVATE DIALOG oDlg CENTERED
   RELEASE FONT oFont

return nil
 

But if you prefer to write your own incremental filter code, you need to support yourself.

Mr.Rao
Can I do this with version 12.04?

Other, can you see this post? (sorry, was written in spanish)

many thank

[nageswaragunupudi]

Mr Mario

Incremental filters were first introduced in version 11.08 ( Aug 2011)
Should work in version 12.04
Please try the sample I posted.

I saw your other posting earlier. Honestly I could not understand what you wanted and so I could not answer you. I try again to understand.

[MarioG]

Mr Rao;
Thank for your respond (in other post too)
sorry for my english (I write from Google Traductor)

I put, xbrowse, in active the Multi selection

First, I selec with shift+clic or ctrl+clic, some registers.
after I do right clic (to open a popup), over a selection and ::aSelected only return the last register selected.
If I do again with Ctrl pressed. ::aSelected, returned all the registers, but not the register where I did clic.

How must i do it that?. This process is clean from Windows Explorer when do a copy files, for example

[MarioG]

sorry!; i write in the ohter post now
