    What is the problem you are facing.

    Have variables that updates based on the timer tick

    No thats not the way.

    Have 2 variables for Minutes and Seconds and start counting them down each time that function is called.

    Use the WM_TIMER event to be used for that function

    Add ON_WM_TIMER() in BEGIN_MESSAGE_MAP

    And then the following Function

    void CTestDlg::OnTimer(UINT_PTR nIDEvent)

    Also there should be a variable called m_seconds

    And then in that function increase for every seconds tick

    i dont know if this is right...
    void CtimerDlg::OnBnClickedButton1()
    {

    UINT sec;
    char u[90];
    CString y;
    sec=SetTimer(60,1000,0);
    sprintf(u,"%d",sec);
    y=u;
    a.SetWindowText(y);


    }
    is the value of sec will decrease from 60-0 every second upon clicking my command button? but how can i update the value of my text box every second?

    You need to have the variables in the class and not local to the function

    I agree but what I meant in the last post was related to C++ and not MFC
