You could try the DateTime.DaysInMonth Method[^]

Hi I used this code but i got error Following error (Month must be between one and twelve.Parameter name: month) this is my code

Dim year As Integer
Dim month As Integer
Dim days As Integer = System.DateTime.DaysInMonth(year, month) //(Month must be between one and twelve.Parameter name: month)
TextBox7.Text = days

You could try giving it an actual year and month...

Dim year As Integer = 2012
Dim month As Integer = 2
Dim days As Integer = System.DateTime.DaysInMonth(year, month)

hi,

ya this above code is working correct, but my requirments is enter the value in runtime only inside textbox i give input is 2012,4 means display the no of days in next textbox(30) i think clear my requirments..

So read the value from the TextBox, use string.Split to break it on the comma, then convert the two numbers to integers with Parse or TryParse.

Dim parts As String() = tbYearAndMonthEntered.Text.Split(","C)
Dim year As Integer
Dim month As Integer
If parts.Length = 2 Then
year = Integer.Parse(parts(0))
month = Integer.Parse(parts(1))
...
End If
