I try to use CB_ADDSTRING to add items to combobox and use it .
I read this https://board.flatassembler.net/topic.php?p=149763, but is not very clear to me.
This is the source code:
Code:
 format PE GUI 4.0
 entry start

 include 'win32a.inc'

 IDD_TEST_DIALOGS = 102
 IDC_COMBOBOX_1 = 1000

 section '.code' code readable executable
  start:

    invoke GetModuleHandle,0
    invoke DialogBoxParam,eax,IDD_TEST_DIALOGS,0,DialogProc,0

  exit:
    invoke  ExitProcess,0 

proc DialogProc uses esi edi ebx,hwnddlg,msg,wparam,lparam

  cmp [msg],WM_INITDIALOG
  je .wminitdialog

  cmp [msg],WM_CLOSE
  je .wmclose

  xor eax,eax
  jmp .quit

  .wminitdialog:

    invoke SetDlgItemText,[hwnddlg],IDC_COMBOBOX_1,szInitText
    jmp .done

  .wmclose:
    invoke EndDialog,[hwnddlg],0

  .done:
    mov eax,1

  .quit:

  ret       
endp

section '.idata' import data readable writeable

  library kernel,'KERNEL32.DLL',\
          user,'USER32.DLL'

  import kernel,\
         GetModuleHandle,'GetModuleHandleA',\
         ExitProcess,'ExitProcess'

  import user,\
         DialogBoxParam,'DialogBoxParamA',\ 
         SetDlgItemText,'SetDlgItemTextA',\
         EndDialog,'EndDialog'

section '.text' readable writeable

  szInitText db "Text set by WM_INITDIALOG.",0

section '.rc' resource data readable

  directory RT_DIALOG,dialogs

  resource dialogs,IDD_TEST_DIALOGS,LANG_ENGLISH+SUBLANG_DEFAULT,mod_exp_dialog

  dialog mod_exp_dialog,\
  'FASM - Dialogs Examples - combobox',0,0,160,160,\
  DS_MODALFRAME+WS_MINIMIZEBOX+WS_POPUP+WS_VISIBLE+WS_CAPTION+WS_SYSMENU,\
  0,0,"Lucida Console",11

  dialogitem 'COMBOBOX',IDC_COMBOBOX_1,-1,10,10,140,12,BS_GROUPBOX+WS_VISIBLE+WS_VSCROLL,0

  enddialog

Changes I made to get string to populate combo.

Code:
;    invoke SetDlgItemText,[hwnddlg],IDC_COMBOBOX_1,szInitText
    invoke SendDlgItemMessage,[hwnddlg],IDC_COMBOBOX_1,CB_ADDSTRING,0,szInitText

  import user,\ 
         ..
         SendDlgItemMessage,'SendDlgItemMessageA',\ 

;  dialogitem 'COMBOBOX',IDC_COMBOBOX_1,-1,10,10,140,12,BS_GROUPBOX+WS_VISIBLE+WS_VSCROLL,0
  dialogitem 'COMBOBOX',"",IDC_COMBOBOX_1,10,10,140,50,WS_VISIBLE+WS_VSCROLL+CBS_DROPDOWNLIST

@Walter: SendDlgItemMessage into resource ?
I think you make a copy paste from internet I saw many examples.
If you try tell me about messaging issue , I know just : SendMessage,'SendMessageA'

The next step , try the SendMessage issue:
The FASM compile the source code but when I run the window form is not show.
I think is something wrong with code after .wminitdialog .
Code:
 format PE GUI 4.0
 entry start

 include 'win32a.inc'

 IDD_TEST_DIALOGS = 102
 IDC_COMBOBOX_1 = 1000

   invoke GetModuleHandle,0
   invoke DialogBoxParam,eax,IDD_TEST_DIALOGS,0,DialogProc,0

  exit:
   invoke  ExitProcess,0

proc DialogProc uses esi edi ebx,hwnddlg,msg,wparam,lparam

   cmp [msg],WM_INITDIALOG
   je .wminitdialog

   cmp [msg],WM_CLOSE
   je .wmclose

   xor eax,eax
   jmp .quit

   .wminitdialog:

   invoke SetDlgItemText,[hwnddlg],IDC_COMBOBOX_1,szInitText
   mov [ctr_item_ID],eax
   mov esi,items
@@:
   or eax,eax
   jz @f
   push eax
   invoke SendMessage,[ctr_item_ID],CB_ADDSTRING,NULL,esi
   pop eax
   add esi,eax
   inc esi
   jmp @r
@@:
  jmp .done

  .wmclose:
    invoke EndDialog,[hwnddlg],0

  .done:
