Creating a short date based on the day of month

I know there must be a simple way to do this but it is eluding me so far. I want to create a short date based on a number entered into a text box. If, for instance, a 12 is entered I would like it to set the default date to 1/12/2004 (current month)

Basicaly I want to do the opposite of this sub that I found in Help

VB Code:

Dim MyDate As Date
        Dim MyDay As Integer
        MyDate = _
            #2/12/1969# ' Assign a date using standard short format.
        MyDay = _
            Microsoft.VisualBasic.DateAndTime.Day(MyDate) ' MyDay contains 12.

Something like this?

VB Code:

Dim myDate As New Date(Now.Year, Now.Month, TextBox1.Text)
 
        ' Interesting that these two lines show different results
        MsgBox(myDate)
        Debug.WriteLine(myDate)
 
        ' I think this is what you need. Check out "Standard
        ' DateTime Format Strings" in MSDN
        Debug.WriteLine(myDate.ToString("d"))

HTH,

Thanks Mike. All I needed was the very first bit of code you gave me.

VB Code:

If TextBox1.Text < 1 Or TextBox1.Text > 31 Then
            MsgBox("Day number not reconized", MsgBoxStyle.OKOnly, "Date Error")
            TextBox1.Clear()
            TextBox1.Focus()
        Else
            Dim mydate As New Date(Now.Year, Now.Month, TextBox1.Text)
            MsgBox(mydate)
        End If

Cool. As a side note, you may consider just trapping the exception that happens when you try to create a new date.

That code would throw an unhandled exception if you run it next month, for example, putting in 30 for the day. Then you have to think of leap years.

Less work catching the exception and saying "Bad Date".

That is not a bad idea especialy when I just realized I have to catch entries that aren'rt numeric.

VB Code:

Try
            Dim mydate As New Date(Now.Year, Now.Month, txtDayCode.Text)
            txtPostDate.Text = mydate
        Catch ex As Exception
            MsgBox("Error: " & ex.Message)
            txtDayCode.Clear()
            txtDayCode.Focus()
        End Try
