Hi,

How i return text selected in a window ?

hWnd:= FindWindow(,"Mozilla FireFox")
SendMessage(hWnd, EM_GETSELTEXT, 0, 0)

i wanna return "_text this string "

Someone can help me ?

Thanks so much.

Lailton,

Try it this way:

Code: Select all  Expand view

local cBuffer := Space( 1000 )

hWnd := FindWindow(,"Mozilla FireFox")
SendMessage( hWnd, EM_GETSELTEXT, 0, @cBuffer )
 

But probably it will not work from PRG code so you have to do the same from C language

Nice Antonio, more no work in PRG.
How make this in C language ?

im trying:

Code: Select all  Expand view

#include "Fivewin.ch"

Function main()

 public oWnd
 define window ownd
 activate window ownd On Right Click Get()

return nil

Function Get()
local hWnd, cRet
      hWnd:= FindWindow(,"Mozilla FireFox")

      cRet = GetSelectedStringByHandle( hWnd )

      msginfo(cRet,"Retorno")

return  

#pragma BEGINDUMP
#include "windows.h"
#include "hbapi.h"

#define GETSELTEXT              1086

HB_FUNC( GETSELECTEDSTRINGBYHANDLE )
{
   HWND hWndCtrl = hb_parnl( 1 );
   CHAR cBuffer[1000];
   SendMessage( hWndCtrl, GETSELTEXT, 0, &cBuffer );
   hb_retc( cBuffer );
}
#pragma ENDDUMP

Lailton,

Don't use & here:

SendMessage( hWndCtrl, GETSELTEXT, 0, cBuffer );

The name of an array is its address

[Enrico Maria Giordano]

The name of an array is its address

Not always. As an example, it is not true in the expression

Code: Select all  Expand view

sizeof( cBuffer )

sizeof is operator, not a function.

[Enrico Maria Giordano]

sizeof is operator, not a function.

That's irrelevant. Still there are cases in which an array name does not decay to the address of its first item. Another example is the unary & (address of) operator. The third case is when an array is initialized using a string literal. Please search Internet for this well known behavior that is covered by the standard.

Well. i think that it´s OK

Code: Select all  Expand view

#pragma BEGINDUMP
#include "windows.h"
#include "hbapi.h"
HB_FUNC( GSELECTED )
{
   HWND hWndCtrl = (HWND) hb_parnl( 1 );
   CHAR cBuffer[1000];
   SendMessage( hWndCtrl, 1086, 0, (LONG) cBuffer );
   hb_retc( cBuffer );
}
#pragma ENDDUMP

but no work with Mozilla, i think that it´s only for GET´s of a windows.

Thanks
