编辑框文本的消息

1.获得编辑框中的文本信息

    TCHAR tem[128];
    HWND hEdit = ::GetDlgItem(m_hWnd, IDC_EDIT1);
    ::SendMessage(hEdit, WM_GETTEXT, 128, (LPARAM)&tem);    

 例:

struct Student 
{
    TCHAR id[10];
    TCHAR name[10];
    TCHAR sex[2];
    TCHAR age[4];
    TCHAR tel[20];
};
BOOL MyDialog::OnIDOK()
{
    Student stu;
    ::SendMessage(::GetDlgItem(m_hWnd, IDC_EDIT1), WM_GETTEXT, 10, (LPARAM)stu.id);
    ::SendMessage(::GetDlgItem(m_hWnd, IDC_EDIT2), WM_GETTEXT, 10, (LPARAM)stu.name);
    ::SendMessage(::GetDlgItem(m_hWnd, IDC_COMBO1), WM_GETTEXT, 2, (LPARAM)stu.sex);
    ::SendMessage(::GetDlgItem(m_hWnd, IDC_EDIT3), WM_GETTEXT, 4, (LPARAM)stu.age);
    ::SendMessage(::GetDlgItem(m_hWnd, IDC_EDIT4), WM_GETTEXT, 20, (LPARAM)stu.tel);


    return 0;
}

看红框内是不是读取数据成功了,

2.设置编辑框中的文本信息

　　TCHAR tem[] = L"你好编辑框!";
    HWND hEdit = ::GetDlgItem(m_hWnd, IDC_EDIT1);
    ::SendMessage(hEdit, WM_SETTEXT, 0, (LPARAM)&tem);

 例:

　　　　 ::SendMessage(::GetDlgItem(m_hWnd, IDC_EDIT1), WM_SETTEXT,0, (LPARAM)L"001");
        ::SendMessage(::GetDlgItem(m_hWnd, IDC_EDIT2), WM_SETTEXT, 0, (LPARAM)L"李尖尖");
        ::SendMessage(::GetDlgItem(m_hWnd, IDC_COMBO1), WM_SETTEXT, 0, (LPARAM)L"女");
        ::SendMessage(::GetDlgItem(m_hWnd, IDC_EDIT3), WM_SETTEXT, 0, (LPARAM)L"23");
        ::SendMessage(::GetDlgItem(m_hWnd, IDC_EDIT4), WM_SETTEXT, 0, (LPARAM)L"13200132");
