Question

我在一个对话框中有两个组合框，问题是我想找出哪个字符串已被选中并从组合框中获取消息。我有以下代码。但问题是，从这段代码中我无法区分选择了哪一个组合框，这个代码导致两个框的索引编号相同。

if(HIWORD(wParam) == CBN_SELCHANGE){
        _formatIndex = SendMessage((HWND) lParam, (UINT) CB_GETCURSEL, (WPARAM) 0, (LPARAM) IDD_IMAGES_MODE);
        _savingModeIndex = SendMessage((HWND) lParam, (UINT) CB_GETCURSEL, (WPARAM) 0, (LPARAM) IDC_COMBOBOX_TIME_FRAME);
    }

Answer 1

实际上我只是找到答案，这是代码：

    if(HIWORD(wParam) == CBN_SELCHANGE){
        if(LOWORD(wParam)==IDD_IMAGES_MODE){
        _formatIndex = SendMessage((HWND) lParam, (UINT) CB_GETCURSEL, (WPARAM) 0, (LPARAM) 0);
        }
        if(LOWORD(wParam)==IDC_COMBOBOX_TIME_FRAME){
        _savingModeIndex = SendMessage((HWND) lParam, (UINT) CB_GETCURSEL, (WPARAM) 0, (LPARAM) 0);
        }           
    }
