Afternoon,

I have a date in my database that is dd/mm/yyyy and I want to be able to in my vb.net program get the first day and last day of current month.

How can I do this?

SELECT * FROM tblPLUSales WHERE siteid = '1' and datestamp = 'startofmonth' between datestamp = 'endofmonth'

Mmm... poorly explained. Explain your problem better, please. What do you want? An SQL sentence? VB.net code? What type of field stores the date value?

Use the following to get the date range for the current month, and use them as the parameters in the query.
Assuming you're using the System.Data.SqlClient namespace, but the same applies for any adapters.
Dim startDate As New DateTime(DateTime.Today.Year, DateTime.Today.Month, 1)
Dim endDate As DateTime = startDate .AddMonths(1).AddDays(-1)
 
Dim query As New SqlCommand("SELECT * FROM tblPLUSales WHERE siteid = '1' " & _
  "AND datestamp BETWEEN @startDate AND @endDate", sqlConn)
query.Parameters.AddWithValue("startDate", startDate)
query.Parameters.AddWithValue("endDate", endDate)
