Можно вопрос от тупого чайника?
Не могу понять как использовать стандартный элемент управления Windows "Combo Box".
Кто-нибудь объяснит, что я делаю не так.
Код моей программы:
Код:
main.cpp
===================================
#include <windows.h>
#include "resource.h"
HINSTANCE hinst;
INT_PTR WINAPI MdlgFunc(HWND hDlg, UINT uMsg, WPARAM wParam, LPARAM lParam)
{
static HWND hwndCombo, hwndList;
LRESULT lResult = 0;
char StrBuffer[300] = {0};
switch (uMsg)
{
case WM_INITDIALOG:
hwndList = CreateWindow("listbox", NULL, WS_CHILD | WS_VISIBLE | LBS_STANDARD, 20, 80, 200, 300, hDlg,(HMENU) 1, hinst, NULL);
hwndCombo = CreateWindow("COMBOBOX", NULL, CBS_DROPDOWNLIST | CBS_HASSTRINGS | WS_CHILD | WS_VISIBLE, 20, 20, 200, 30, hDlg, 0, hinst, NULL);
break;
case WM_COMMAND:
switch(LOWORD(wParam))
{
case IDCANCEL :
EndDialog(hDlg, LOWORD(wParam));
return (INT_PTR)TRUE;
break;
case IDC_BUTTON1 :
GetDlgItemText(hDlg, IDC_EDIT1, StrBuffer, sizeof(StrBuffer));
if(StrBuffer != 0)
lResult = SendMessage(hwndCombo, LB_ADDSTRING, 0,(LPARAM) &StrBuffer);
break;
case IDC_BUTTON2 :
GetDlgItemText(hDlg, IDC_EDIT1, StrBuffer, sizeof(StrBuffer));
if(StrBuffer != 0)
lResult = SendMessage(hwndList, LB_ADDSTRING, 0,(LPARAM) &StrBuffer);
break;
case IDC_BUTTON3 :
break;
}
//сообщения самого комбобокса
if((HWND) lParam == hwndCombo)
{
switch (HIWORD(wParam))
{
case CBN_EDITCHANGE :
SendMessage(hwndCombo, WM_GETTEXT, sizeof(StrBuffer), (LPARAM) &StrBuffer);
SetDlgItemText(hDlg, IDC_EDIT1, StrBuffer);
break;
case CBN_DROPDOWN :
StrBuffer[0] = StrBuffer[0];
//none
break;
}
}
break;
case WM_NOTIFY:
break;
default:
break;
}
return(FALSE);
}
int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, PSTR szCmdLine, int iCmdShow)
{
hinst = hInstance;
DialogBox(hInstance, MAKEINTRESOURCE(IDD_MAIN), NULL, MdlgFunc);
