Might be a noob question - but assuming I've got a dialog resource with a COMBOBOX dialogitem, how do I add a string to the combobox?

Here it is:

Code:

        invoke        GetDlgItem,[hdlg],IDC_CBO1 ;this will get the handle of the ComboBox
        mov     [Trigger_CBO],eax ; Trigger_CBO holds the handle
    invoke  SendMessage,[Trigger_CBO],CB_ADDSTRING,NULL,Trigger0 ;This will add the string to the combobox - Trigger0 holds the string
  invoke  SendMessage,[Trigger_CBO],CB_ADDSTRING,NULL,Trigger1
        invoke  SendMessage,[Trigger_CBO],CB_ADDSTRING,NULL,Trigger2
        invoke  SendMessage,[Trigger_CBO],CB_ADDSTRING,NULL,Trigger3
        invoke  SendMessage,[Trigger_CBO],CB_SELECTSTRING,NULL,Trigger3 ;This will select the item you want from the combobox list

New problem with my dialog box. It works fine in an EXE program but in a DLL Windows can't find the menu resource, giving me an extended error code of 1812. Is there an emoticon for beating my head on the wall?

I guess your hInstance-parameter is wrong

Code:

push 0
push WndProc
push 0
push IDD_DIALOG
push [hInstance] ; <--
call [DialogBoxParam]

This parameter needs to be the imagebase of your pe file in memory, which you get via DllMain

so if your dll gets loaded, you should save hinstance/hmodule/the imagebase like this

Code:

format PE GUI 4.0 DLL
entry DllMain

include 'win32ax.inc'

section '.text' code readable executable

DllMain:
  cmp     byte [esp+8],DLL_PROCESS_ATTACH
  jnz        .return
  mov        eax,[esp+4]
  mov    [hInstance],eax
 .return:
  mov       eax,TRUE
  retn      0Ch

If not you should elaborate a little and post some code

Ah! That makes sense, I'll give it a try. Thanks.

EDIT: Works, thanks!
