the hWnd comes form an EditorGadget() but it fails here.

Is the editor gadget from a different process\application by any chance? If so, this method will not work.

Yes, it's from another process/application. I wanted to have this feature because I am creating the "peek" program.

EDIT: is there any chance to get the text of an editorgadget of another process?

The API method should work in this case.

Sorry to send you off on a goose chase; I didn't realise the gadget was from another process.

no problem, but the api way (in your first post) doesn't work here. the program crashes before it readed the text.

you should use SendMessage_() with #EM_GETTEXTEX and fill the structure GETTEXTEX.

The following works here.

Code: Select all

;Make sure this program is running.

If OpenWindow(0, 0, 0, 322, 150, "EditorGadget", #PB_Window_SystemMenu | #PB_Window_ScreenCentered) And CreateGadgetList(WindowID(0)) 
  EditorGadget(0, 8, 8, 306, 133) 
  SetGadgetText(0,"HELLO!")
  Repeat : Until WaitWindowEvent() = #PB_Event_CloseWindow 
EndIf

Run the above program first. The next program will display the contents of the editor gadget in the already running program.

Code: Select all

hwnd=FindWindow_(#Null, "EditorGadget") 
If hwnd
  redit=FindWindowEx_(hwnd, #Null, "RichEdit20A", #Null) 
  tlen = SendMessage_(redit, #WM_GETTEXTLENGTH, 0, 0) + 1 
  edit$ = Space(tlen) 
  SendMessage_(redit, #WM_GETTEXT, tlen, @edit$) 
  Debug edit$
EndIf

hint: they don't make it that easy

this one should work even if richedit is in ascii or unicode.

Code: Select all

Enumeration ; GT_
  #GT_DEFAULT
  #GT_USECRLF
  #GT_SELECTION
EndEnumeration
Enumeration ; GTL_
  #GTL_DEFAULT = 0
  #GTL_USECRLF = 1
  #GTL_PRECISE = 2
  #GTL_CLOSE = 4
  #GTL_NUMCHARS = 8
  #GTL_NUMBYTES = 16
EndEnumeration

Procedure.s GetRichEditText(hWindow.l, limit.l)
  
  Protected text.s, gt.GETTEXTEX, gtl.GETTEXTLENGTHEX
  
  If IsWindowUnicode_(hWindow)
    gtl\codepage = 1200
  Else
    gtl\codepage = #CP_ACP
  EndIf
  
  gtl\flags = #GTL_DEFAULT|#GTL_NUMCHARS
  
  gt\cb = SendMessage_(hWindow, #EM_GETTEXTLENGTHEX, @gtl, #Null)
  gt\flags = #GT_DEFAULT
  gt\codepage = gtl\codepage
  
  text = Space(gt\cb)
  
  SendMessage_(hWindow, #EM_GETTEXTEX, @gt, @text)
  
  ProcedureReturn text
  
EndProcedure

If OpenWindow(0, 0, 0, 320, 240, "test", #PB_Window_SystemMenu|#PB_Window_ScreenCentered)
  
  If CreateGadgetList(WindowID(0))
    EditorGadget(0, 5,  5, 200, 100)
  EndIf
  
  SetGadgetText(0, "hello world !")
  
  Debug GetRichEditText(GadgetID(0))
  
  Repeat :  Until WaitWindowEvent() = #PB_Event_CloseWindow
  
EndIf
