c++ win32 : adding values to ComboBox

c++, combobox, winapi

Solution

thank you so much for your help. but I notice I didnt have problem in my code, simply the size of the ComboBox in .rc file was quite small (because of my lack of experiance in c++ API), so I change it to 42 now I can see my items. here is the edited code :

`COMBOBOX IDD_TRIGGER_MODE, 64,22,69,42,WS_CHILD|WS_VISIBLE|CBS_DROPDOWNLIST`

Problem

Im sure this question is so easy for all you experts, but I am new to C++ and trying to add a comboBox to a "Option" Dialog in my program, I have done the following, but still can't see any item in Combo box can you please tell me what I am missing here. in Resourse.h : `#define IDD_TRIGGER_MODE 201` in Project.rc : `COMBOBOX IDD_TRIGGER_MODE, 64,22,68,14,WS_TABSTOP | WS_VSCROLL | CBS_DROPDOWN` any in the .cpp file I have the folliwng codes : ``` LRESULT CALLBACK WndProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam){ int wmId, wmEvent; PAINTSTRUCT ps; HDC hdc; switch (message) { case WM_COMMAND: ///Other codes/// case IDM_OPTIONS: g_hToolbar = CreateDialog(hInst, MAKEINTRESOURCE(IDD_OPTION_BOX), hWnd, ToolDlgProc); if(g_hToolbar != NULL) { ShowWindow(g_hToolbar, SW_SHOW); } break; default: return DefWindowProc(hWnd, message, wParam, lParam); } break; ///Other codes/// } ``` the ToolDlgProc function : ``` INT_PTR CALLBACK ToolDlgProc(HWND hDlg, UINT message, WPARAM wParam, LPARAM lParam) { UNREFERENCED_PARAMETER(lParam); HWND fgModes; switch (message) { case WM_INITDIALOG: fgModes = ::GetDlgItem(hDlg, IDD_TRIGGER_MODE); fgModes = GetDlgItem(hDlg, IDD_TRIGGER_MODE); if(fgModes!=NULL){ if(SendMessage(fgModes,CB_ADDSTRING,0, reinterpret_cast<LPARAM (_T("FreeRun")))==NULL){ return (INT_PTR)FALSE ; } return (INT_PTR)TRUE; } case WM_COMMAND: if (LOWORD(wParam) == IDOK || LOWORD(wParam) == IDCANCEL) { EndDialog(hDlg, LOWORD(wParam)); return (INT_PTR)TRUE; } break; } return (INT_PTR)FALSE; } ``` I appricate it for any idea to solve this problem, Thank you
