Creating The Subtract Button On A Calculator?
Jan 7, 2010I'm completely new to programming and wondered if you could help me. I've designed a simple calculator that can add numbers together but am now trying to create a subtraction button. This seems more complicated, I've searched various forums but am a little confused and wondered if any of you can help or point me in the right direction. Here is the coding I've done for the Add button (cmdPlus):

Containing A Date Textbox And A Submit Button And A Close Window Button?
Apr 23, 2010I have a form containing a date textbox and a submit button and a close window button. The date textbox onblur calls a javascript function which checks for date validation and some other logic and displays some alert messages. The date on the textbox is always selected and onfocus. My problem is when I try to click the close window button with/without changing the date the alert messages from the onblur logic are displaying and I am unable to close the window. I tried using onchange instead of onblur but onchange too works when a control looses focus. it works fine when I donot change the date but when I change the date and hit the close window button it too displays the alert messages and the window does not close. Please suggest me what will be my best option.

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.
