A masked edit control

Download Source Code


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

    Thanks for the cool control.  May I point out one limitation.  When you do the following, it seems to get confused.
    
    

    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.....

    if (!m_bMaskKeyInProgress && m_bUseMask && !m_strLiteral.IsEmpty())
    {
    int startPos, endPos;
    GetSel(startPos, endPos);
    // make sure the string is not longer than the mask
    if (endPos < m_strLiteral.GetLength())
    {
    UINT c = m_strLiteral.GetAt(endPos);
    if (c != '_') { // Debuged by Sang-il, Lee T.T
    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.
