View 1 RepliesDateTimePicker Values And SQL Statements?
Jan 9, 2009I'm using this to set the default values of the DTP controls on Form_Load:
Dim dtNow As Date = Now()
dtpStart.Value = dtNow.AddDays(-7)
dtpEnd.Value = dtNow
The problem is, when those values are grabbed from the DTP controls, Access is treating them as wrong datatypes.However, if I manually rechoose the same dates, the SQL statement will work.So, what seems is happening is that it isn't recognizing the initialized values as valid date/time values until I physically choose them.Anyone know a workaround for this or what is really going on and how to resolve this?

I need a way to ensure that the dtpReturn date selected is after the dtpPickup, and not before. How do I do that? And also, how do I get the values of the datetimepicker selected controls? Also, how can I set the values of the datetimepickers to these two private variables?

View 12 RepliesSubtract Query In VB?
Sep 11, 2010I'm stuck on writing a query to subtract "Amount to pay" with "amount paid", my assignment sheet says to 'use two queries and subtract in vb'. but i still don't really understand it
What the program is supposed to do is:
1. the user types in a specific customer id
2. the button "What is owed by the Customer ID?" runs the query
3. the query returns and opens a HTML with the customer id, the amount to pay, the amount paid and the total amount.so far what i've come up with is:
sSql = "SELECT CustID, SUM(AmountToPay) As AmountOwing, SUM(AmountPaid) As PaidOff FROM Order, Payment WHERE Order.CustID = Payment.CustID AND CustID = " & sSearchValueA & "GROUP BY CustID;"

Subtract Two Dates Without Using Hours In VB
Nov 3, 2011I'm writing a program that checks something once a day. When the property has been checked, I store the "Now" value as LastCheckedDate. Since this is a dateandtime, in includes both the value of the date and the value of the time. The next time the program is run, I want to determine if the current value of Now has a different date than the LastCheckedDate. The problem is that functions like Datedif subtract the two values using the times, so if the first check was at 16:30 on 11/2/2011 and the second check was at 9:05 on 11/3/2011, the result is about 16 hours, which is 0 days.
