Hi
I got the solution for this,
For Current date
Dim sCurrentDate As String
sCurrentDate = DateTime.Now.ToString("ddd") & vbCrLf & DateTime.Now.ToString("M/d") & vbCrLf & "(Today)"
For One day Before
Dim sPreviousDate As String
sPreviousDate = DateTime.Now.AddDays(-1).ToString("ddd") & vbCrLf & DateTime.Now.AddDays(-1).ToString("M/d") & vbCrLf & "(Yesterday)"
For DaybeforeYesterday
Dim sPreviousDate As String
sPreviousDate = DateTime.Now.AddDays(-2).ToString("ddd") & vbCrLf & DateTime.Now.AddDays(-2).ToString("M/d")
