I have 2 SQL tables (A & B) with dates in the format DD/MM/YYYY and time, for example 01/03/2012 00:00:00. In my VB.net application I am looking to count the number of records in table A which have a date less than the one in table B. I have no problem getting the dates from the database. I have extracted the date in table B and stored this in the program. how to compare the dates within the SQL query.

"select count(records) as totalRecords from table A where date < " & dateBvariable & ""
I have a txt file with a few settings that get loaded into the Program. These are put into an array. As the array holds different types (int, string, dates etc) its set to object type.
What i am trying to fingure out is how to check the date is a valid format, by returning a false value so i can have a msgbox pupup and say the date in the file is invalid. I cant use isdate() on the string from the file as even if the date format is correct its a string not a date type so i have to convert it first (which is the point it throws an error).

Is there any way to check date and hour without using two Timers?
Right now i have this for the date:
Private Sub Timer1_Tick(ByVal sender As Object, ByVal e As System.EventArgs) Handles Timer1.Tick
Timer1.Stop()

PS (again): I thought about setting the Timer1 interval to 60000miliseconds, so that it would check the time everysingle step of the way (or maybe 10 minutes...), but I don't want the app to lag, so... How can i implement a Background Worker?
I need to check my field in format ddMMyyyy(ex 12/03/1990) whether in interval of two dates that user picks from two date picker controls. Two date pickers are in custom format dd/MM. It does not matter for me if its between particular years. I need just to know if given Birthday belongs to interval taken from screen. Each datepicker gives values dd/mm/yyyy. I do not know how to check it. For example: Given date 12/03/1990 . User select two values from screen: From 01/01/1950 Upto 30/04/1949(or 1990, or 2000) Result should be True.Because 12 march is between 01 Januar and 30 April.
