Getting The Number Of Days Between Two Dates

The user has to enter the other date into TextBox7.Then I try to use this function that i made. The code does not work, I get an exception. I have never made a function before so I don't really know much about them. I honestly don't even know if this is possible,

Nov 20, 2011

How do I calculate the difference between two dates to display as a number in days?I have 2 text boxes (txtHStart_Date & txtHEnd_Date) I have used an Ajax Calendar Extender to enter the dates in each of these text boxes.I would like to get the difference between these two dates to show in a seperate text box (txtNoOfDays)

I've seen the timespan function but can seem to get this to work. I'm not to sure how to declare the text boxes as the dates I would the calculation to be made from

Code:

Dim D1 As Date
Dim D2 As Date
Dim ts As New TimeSpan
D1 = txtHStart_Date.Text
D2 = txtHEnd_Date.Text
ts = D2 - D1

But I know this isn't right. I also don't know how to get it to display in the 3rd TextBox.

Interval Of Days / Months / Years Between 2 Given Dates

Dec 21, 2011

I've been given two dates that takes their values from two respective dtpickers.I've got to calculate the exact amount of days, months and years between them.[code]The problem is that this function gives me ALL the amount of respective days, months and years passed, but I need to split them up in the correct way. Ex, between 28/2/98 and 13/1/2007 the result should be 15 days, 10 months and 8 years. And above all, the result is that the function indicates one month more (or one year more) with only one day (or month) passed between the two dates!

Application That Allows User To Select Or Enter Into A Combo Box Number Of Days A Person Will Work

Oct 28, 2009

Create an application that allows the user to select or enter into a combo box the number of days a person will work, and calculates the total amount of pay she will receive over that period of time. Salary is one penny the first day, two pennies the second day, four pennies the third say, and continuing to double each day.

The combo box must list the following items: 30, 180, 365, and 1000. Must be the default drop down box. Use a validating event procedure on the combo box.

The program should go through a loop once for each day, doubling the number of pennies with each iteration of the loop. You will need a running totl of the number of pennies that you add to with each iteration. To calculate the total amount of pay, multiply the total number of pennies by .01 and show the result in currency format.

Public Class Form1

Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ComboBox1.SelectedIndexChanged
