Sérgio,

Please test this example:

Code: Select all

#include "FWCE.ch"   
 
function Main()         
 
   local oDlg, cValue, aData := { "one", "two", "three" }         
 
   DEFINE WINDOW oWnd
 
   @ 2, 2 COMBOBOX cValue ITEMS aData SIZE 80, 80
 
   ACTIVATE WINDOW oWnd   
 
return nil 
 

[rasptty]

this example not open the combobox, in Windows Mobile 6.1 build SO CE 5.2.20764

the previous version works fine


this bug is true only in the last version of windows 6.1

[rasptty]

Example 1 -> in dialog works well in all versions of windows mobile
#include "FWCE.ch"
function Main()
local oDlg, cValue :="One"
DEFINE DIALOG oDlg TITLE "Combos" SIZE 200, 100
@ 1, 1 COMBOBOX cValue ITEMS { "One", "Two", "Three" } OF oDlg
ACTIVATE DIALOG oDlg CENTERED
return nil


Example 2
this version SO CE 5.2.20764 does not work the combobox do not open Why?

in version SO CE 5.2.19965 works ok

#include "FWCE.ch"
function Main()
local oWnd, cValue :="One"
DEFINE window oWnd TITLE "Combos"
@ 1, 1 COMBOBOX cValue ITEMS { "One", "Two", "Three" } OF oWnd
ACTIVATE window oWnd
return nil

finally the bug is in the window "DEFINE WINDOW", in the DIALOG Class works fine..
My program has thousands der lines please analize the bug, my client has the 35 PDA's in standby

any idea?, thank you
Best Regards

Sérgio,

WM 6.1 5.2.20764 may have changed a notification value. Its simple to locate it and fix it

Please copy the entire source\classes\window.prg contents at the bottom of the example that I provided you. Then, move these lines to the top of the PRG:

Code: Select all

static oWndMain, oWndDefault, oToolTip
static aWindows := {}
 

Comment this line in FiveWin.ch:

Code: Select all

      // static bError
 

Now we need to modify Method Command() as it is the one that receives the notifications:

Code: Select all

METHOD Command( nWParam, nLParam ) CLASS TWindow

   local nNotifyCode := nHiWord( nWParam )
   local nID := nLoWord( nWParam )
   local hWndCtl := nLParam

   LogFile( CurDir() + "\notify.txt", { nNotifyCode, nWParam, nLParam } )

   if nNotifyCode == 0 // MenuItem command
      if ::oMenu != nil
         ::oMenu:Command( nId )
      endif
   endif      

   if nID == 1 .and. nNotifyCode == BN_DONEBUTTON
      ::End( 1 )
   endif   
   
   if hWndCtl != 0
      do case
         case nNotifyCode == BN_CLICKED
              SendMessage( hWndCtl, FM_CLICK, 0, 0 )
          
         case nNotifyCode == CBN_SELCHANGE
              LogFile( CurDir() + "\notify.txt", { "it is a CBN_SELCHANGE notification" } )
              SendMessage( hWndCtl, FM_CHANGE, 0, 0 )
      endcase
   endif   
   
return nil   
 

Run the example and check the created notify.txt. You should see values like these:

Code: Select all

01/01/03 12:02:00: 3    196709  2080462944  
01/01/03 12:02:01: 7    458853  2080462944  
01/01/03 12:02:31: 1    66536   2080463168  
01/01/03 12:02:31: it is a CBN_SELCHANGE notification   
01/01/03 12:02:31: 9    589925  2080462944  
01/01/03 12:02:31: 8    524389  2080462944  
01/01/03 12:02:31: 1    65637   2080462944  
01/01/03 12:02:31: it is a CBN_SELCHANGE notification   
 

Please post here the values that you get. Thanks

Sergio,

These are the ComboBox notifications from the Windows API:

Code: Select all

/*
 * Combo Box Notification Codes
 */
#define CBN_ERRSPACE        (-1)
#define CBN_SELCHANGE       1
#define CBN_DBLCLK          2
#define CBN_SETFOCUS        3
#define CBN_KILLFOCUS       4
#define CBN_EDITCHANGE      5
#define CBN_EDITUPDATE      6
#define CBN_DROPDOWN        7
#define CBN_CLOSEUP         8
#define CBN_SELENDOK        9
#define CBN_SELENDCANCEL    10
 

It looks that your application receives a CBN_SELENDCANCEL instead of a CBN_SELCHANGE.

[Antonio Linares]

Sérgio,

Please try this fix in the previous example:

Code: Select all

#define CB_SHOWDROPDOWN 335

METHOD Command( nWParam, nLParam ) CLASS TWindow
   ...
         case nNotifyCode == 10
                MsgBeep()
                ::SendMsg( CB_SHOWDROPDOWN, 1 ) 
  ...
 

Or

Code: Select all

::PostMsg( CB_SHOWDROPDOWN, 1 ) 
 

instead of ::SendMsg()

Sérgio,

> Wmobile 6.1 build SO CE 5.2.20764

We need to locate an image file of such WM version for the emulator to be able to test it here.

Please help us to locate it. Once we have it, then we will be able to test it here and do more tests to check it.

[Antonio Linares]

Sérgio,

Please do this test in the initial example (the one including Class TWindow):

METHOD Command() VIRTUAL

and try it again, thanks

METHOD Command() VIRTUAL
