How i get the Handle from an item in my Dialog Box

[ferby]

Hello,

i have create a dialog box

Code Select Expand


    Dialog "Dialog With Icon", "Tahoma", 9, \          ; caption,font,pointsize
            WS_OVERLAPPED or DS_CENTER or WS_VISIBLE, \     ; style
            3, \                                            ; control count
            0,0,166,70, \                                  ; x y co-ordinates
            1024                                            ; memory buffer size

    DlgStatic "MASM32 Pure And Simple Dialogs",0,8,8,150,9,100
DlgEdit WS_BORDER or WS_TABSTOP,8,18,150,12,1000
DlgButton "OK",WS_TABSTOP,8,33,150,15,IDOK

    invoke GlobalAlloc,GMEM_FIXED or GMEM_ZEROINIT, 32
CallModalDialog hInstance,h_window,DlgProc, eax
    invoke GlobalFree, eax


when the OK Button is presst i want to get the text from the EDIT Item


maybe so:

Code Select Expand

DlgProc proc hWin:DWORD,uMsg:DWORD,wParam:DWORD,lParam:DWORD

; COMMAND
    .if uMsg == WM_COMMAND
   
    ; OK BUTTON
      .if wParam == IDOK
     
      invoke SendMessage, ????????, WM_GETTEXT, NULL, NULL
      ; SAVE TEXT [..]
        invoke EndDialog,hWin,0
      .endif

; CLOSE
    .elseif uMsg == WM_CLOSE
      invoke EndDialog,hWin,0
    .endif

xor eax, eax
    ret

DlgProc endp


but what is the handle for the edit item to get the text with invoke SendMessage, ????????, WM_GETTEXT, NULL, NULL

GetDlgItem will return the handle of the item given it's ID

invoke GetDlgItem, hDlg, 1002
mov hControl, eax

This dialog is from a resource file, but I can't get the column to add.

DlgCarsProc proc hWnd:HWND, iMsg:DWORD, wParam:WPARAM, lParam:LPARAM
;===================================================================

   LOCAL lvc:LV_COLUMN
   
   .if iMsg == WM_INITDIALOG
      invoke GetDlgItem,hWnd,IDC_LSV_CARS
      mov    hLV, eax 
      mov    lvc.imask, LVCF_TEXT + LVCF_WIDTH
      mov    lvc.pszText, offset chDlgCarsHeading1
      mov    lvc.lx, 150
      invoke SendMessage, hLV, LVM_INSERTCOLUMN, 0, addr lvc
   .elseif iMsg == WM_CLOSE
      invoke EndDialog, hWnd, NULL   
   .else
      mov    eax, FALSE
      ret   
   .endif
   mov    eax, TRUE
   ret
   
DlgCarsProc endp

GetDlgItem will return the handle of the item given it's ID

...provided the dialog was created with DialogBoxParam and not CreateDialogParam... ::)

If you're familiar with the OllyDbg debugger, load the executable into that, scroll down to a few lines before the call to GetDlgItem, press F2 to place a breakpoint there, press F9 to execute to the breakpoint, then press F8 to step through the call to GetDlgItem. You might be getting this result:

No luck. I tried debugging as was suggested, but it looks fine. The dialog opens, but there is no heading.

[EDIT]

Per MSDN: "Columns are visible only in report (details) view."

I mistakenly thought this was the default. I'm back on track now.
