RE: [Dev-C++] combobox usage help

[Chris S. <CS...@Ai...>]

I note that the ID of your combo box is IDC_OPTIONS, but when you call =
SendDlgItemMessage you use IDC_MY_COMBO. Unless these two are defined =
the same, the function call will apply to another dialog item, and that =
may be what is causing the crash. The lack of the WS_VSCROLL option may =
also be preventing the vertical scroll bars.=20

FYI: I have used this code and know it works:=20

Define the combo box in the .rc file:=20


    	COMBOBOX        IDC_COMBO_BOX5, 335, 280, 30, 60, CBS_HASSTRINGS | =
CBS_DROPDOWNLIST | WS_VSCROLL

Then to add a "N" to the combo box use.=20

	SendDlgItemMessage(hwnd, IDC_COMBO_BOX5, CB_ADDSTRING, 0, (LPARAM) =
(LPCTSTR) "N");=20

Let me know how you go.=20

Regards
Chris=20

Subject: [Dev-C++] combobox usage help


Hello all Dev-cpp-users,

   I got big problem that I can't pass... in my app I want to use =
combobox,
i.e. in .rc file defined like this:
COMBOBOX        IDC_OPTIONS, 15, 80, 100, 11, WS_TABSTOP | =
CBS_DROPDOWNLIST | CBS_HASSTRINGS
i know how to add new string to control but I can't force this control =
to
show contents using dropdown list... when I click only line shows below =
but
nothing else happens - I'm sure I need one more function, but which?? =
When I
try to process CBN_DROPDOWN and in response send:
SendDlgItemMessage( hwnd, IDC_MY_COMBO, CB_SHOWDROPDOWN, TRUE, 0 );
my program just crashes... even tried very simple dialog with 3 =
controls,
but the same happens... help!

--=20
regards, Zodiaq...
