I got this masked edit control code from someone (I can't remember whom it was). If anyone wishes to lay claim to the original they are more than welcome. I have found this quite useful. So I can't lay claim to doing all or even most of this. However I have enhanced the code to deal with times as well as dates.

I have also added validation of the keystrokes so that invalid times i.e. > 23:59 are not allowed. (I have limited the time validation to minutes. It would be no great effort to add in the seconds. Validation for dates is a little more difficult. Validation is limited to months < 13 and days < 32.

i.e you can put in 31/02/1998 for example.

Ok how to make it work. There are three classes

  • CMaskEdit
  • CDateEdit
  • CTimeEdit

Include the two files MASKED.CPP and MASKED.H in your project. Also include <afxdao.h> for the COleDateTime features if you already haven't. Modify the include line that says #include "myproj" to point to your project. Create a CEdit control and declare a control variable in your dialog then modify the CEdit declaration in the class header to say either CDateEdit or CTimeEdit

CDateEdit:

Pass your time to CDateEdit with 

	CDateEdit myeditctrl;
	myeditctrl.SetDate(COleDateTime var);

and get the edited result back with 

	COleDateTime var = myeditctrl.GetDate();

CTimeEdit:

Pass your time to CTimeEdit with 

	CTimeEdit myeditctrl;
	myeditctrl.SetTime(COleDateTime var);

and get the edited result back with 

	COleDateTime var = myeditctrl.GetTime();

and there you have it.

Please feel free to modify any modifications I have made. These are stated with //added this

    COleDateTime oDateTime;

    ASSERT(oDateTime.SetTime(0,0,0)==0);

    m_edtTimeOfDay.SetTime(oDateTime);


    It leaves the edit control blank.  The fix is to add/change the following function to:


    {void FormatCOleDateTime(CString& strData, COleDateTime DateTime, int len) 

    { 

      strData = ""; 

      if (DateTime.m_dt == 0) 

      { 

        if(len == 5) 

          strData = "00:00"; 

      } 

      else if (len == 8) 

        strData = DateTime.Format("%d/%m/%y"); 

      else if(len == 5) // added these two 

       strData = DateTime.Format("%H:%M"); 

      else 

        strData = DateTime.Format("%d/%m/%Y"); 

    } 


    

    Now she's cool.....

    		  SetSel(endPos+1,endPos+1);

    	  }

    	}

      }

    }


    Original code doesn't work. (In my visual C++ 6.0)

    Why use SendMessage in SendChar to move cursor.


    this code has bug. if "00--00--00", doesn't work. But

    I have no needs. If you needed, It's your job.
