Hi
in formview class,i have a bitmap having random data displaying at different positions of bitmap on runtime.I have four fields in my binary table from where this random data is comming.Now i have to give diffrent colors to that random numbers by applying different conditions.Problem is that when i run program and then by right clicking on that number ,then my conditions are applied on that.whereas in my right click event,only information of that variable is shown on the screen.How can i overcome this problem.My condition should work at run time.Is there any problem in SetTextColor function.
void CPPCView::OnTimer(UINT nIDEvent)
{
    CDC* my_cdc;
CTime curTime=CTime::GetCurrentTime();
      switch(nIDEvent)
      {
      
      case 1:

        my_cdc=m_ctrlBmp.GetDC ();
          my_cdc->SetTextColor(RGB(0x00,0xFF,0x00));
        my_cdc->SetBkColor(RGB(0,0,0));
if(!LLAlarm[varNew] && !LowAlarm[varNew] && !HighAlarm[varNew] && !HHAlarm[varNew])         //if fields are empty
            {
 m_sCount.Format("%.1f",fCurrValue);//fcurrvalue is random number
        my_cdc->SetTextColor(RGB(0x00,0xFF,0x00));            //color green
          my_cdc->TextOut((ptA.x-25),(ptA.y-5), m_sCount);
            }
            else
            {
            if((fCurrValue<LLAlarm[varNew]) && (fCurrValue>=LScale[varNew]))   //LLAlarm and LScale are name of fields
      {
      m_sCount.Format("%.1f",fCurrValue);

  my_cdc->SetTextColor(RGB(255,0,0));  //color red
  my_cdc->TextOut((ptA.x-25),(ptA.y-5), m_sCount);
                    }
else if((fCurrValue>=LLAlarm[varNew]) && (fCurrValue<m_lAlarm))  //m_lAlarm is name of field
                    {
      m_sCount.Format("%.1f",fCurrValue);
       my_cdc->SetTextColor(RGB(255, 0, 255)); //color magenda
     my_cdc->TextOut((ptA.x-25),(ptA.y-5), m_sCount);
                    }
      
   else if((fCurrValue>=HHAlarm[varNew]) && (fCurrValue<HScale[varNew]))
                    {
m_sCount.Format("%.1f",fCurrValue);
 
my_cdc->SetTextColor(RGB(255,0,0));
       
my_cdc->TextOut((ptA.x-25),(ptA.y-5), m_sCount);
                    }
else if((fCurrValue>=m_hAlarm) && (fCurrValue<HHAlarm[varNew]))
                    {
      m_sCount.Format("%.1f",fCurrValue);
       my_cdc->SetTextColor(RGB(255, 0, 255));//magenda
       
      my_cdc->TextOut((ptA.x-25),(ptA.y-5), m_sCount);
                    }
      else
                    {

          m_sCount.Format("%.1f",fCurrValue);
      my_cdc->SetTextColor(RGB(0x00,0xFF,0x00));//green
     my_cdc->TextOut((ptA.x-25),(ptA.y-5), m_sCount);
                  }
                    }
               
                    }  
//             }
                  }
           
      
            UpdateData(false);
            break;

All drawing code should be only in OnPaint function or in functions called from it. In OnTimer and any other message handler you should only set some member variables and invalidate window. After window is invalidated OnPaint function redraws it according to current state.

void CPPCView::OnTimer(UINT nIDEvent)
{
    // set here text coordinates, colors etc. keeping them in the class members

    Invalidate();
    UpdateWindow();    // indirect call to OnDraw

    CView::OnTime(nIDEvent);
}

void CPPCView::OnDraw( CDC* pDC )
{
    pDC->...

   // All drawing code should be here
}
