        DateTime myDate = Convert.ToDateTime("2/19/2015");
        int mon = myDate.Month;
        int year = myDate.Year;

More simplified approach:
Module Module1
	Sub Main()
		Dim dt = New DateTime(Now.Year, Now.Month, 1).AddMonths(1)
	End Sub
End Module

Open in new window

Produces the following output -Capture.JPG-saige-

Hi VBdotnet2005;

This should give you what you need.

Dim MyDate As Date = DateTime.Today
Dim DaysInMonth As Integer = DateTime.DaysInMonth(MyDate.Year, MyDate.Month)
Dim MonthStartDate As String = New DateTime(MyDate.Year, MyDate.Month, DaysInMonth).AddDays(1)
