I am trying to get a function so when i press the calculate button it somes up with sales totals and sales commissions. this is just a simple project i just cant find the answer.
I have a program that I wrote in vb 2010 that keeps track of employee times in a database. It figures hours worked based on a range of dates selected using two DateTimePickers.I have it successfully working at this point to figure hours worked per day in the range for it's current practical use. But I was wanting to extend it so that it would handle over night shifts properly in case they did ever occur.Right now my code looks like this and it works for my current application:
vb Public Sub ConvertTimesTableToHoursTable(ByVal timesTable As DataTable, ByVal hoursTable As DataTable)
Im Building a auction application and i need to catch the exceptions i.e if two people press the bid button at the same time i need to capture that exception and figure out who was has the highest bidder out of the pair of them then show the relevant message, my question is how can i achieve the above?
I am sure there is a better cleaner way to do this but again I am just starting to feel VB.Anyway, what I am trying to do is get the calculations to work in real time, the form loads with the default radio selection and when the user click the controls, the prices starts to change like add and subtracts.Using the button is also an issue since the increment on the check boxes goes up by one even when the user click on another radio button.[code]
I made a sort of downloader program in Visual Basic 2010, and it downloads okey. It reports the full size of the file, and how much that has been downloaded right now and the percentage.
But, a function that i am missing is to show the user how much time is left on the current downloading. I have searched for it, but i couldn't find any solution that would work.I should also mention that i use a webclient for the actual downloading part.

The idea with this form is to add the futures which is calculated when the button is pushed but I need the list to update every time and show the values each time to which the previous value is added to the new calculation, e.g. of what it should look like in listbox:
Year 1: $1,290.93 Year 2: $2,724.32 Year 3: $4,350.76 etc....
I have been working on this a while and I am at a standstill, I was given a function to clear the form everytime it calculates but I don't know how to implement it, I am new to VB. Here is what I have so far:
Public Class frmFutureValue Private Sub btnCalculate_Click(ByVal sender As System.Object, _ ByVal e As System.EventArgs) Handles btnCalculate.Click

I will paste the code below
With a Time value in my program. Basically, I am importing a travel Time from a database e.g. 3:45 so it takes 3 hrs and 45 minutes to get from a to b. I then want to double this - 3:45 * 2 = 7:30, and then want to multiply it by a cost e.g. travel is charged at 25 per hour. so it would be total travel time = 7:30. Travel cost = 25. Total Travel Cost = 7:30 * 25. In the access db, it is stored as a text field, and then imported in vb as a string.
