How to compute Date Difference in VB.NET

In this article, i will introduce another some twist of the Date Function in VB.NET. I haven't posted for two days because of I was tasked to be a panelists for the Thesis Defense in Computer Engineering.But now I'm back! Hurray! haha :D So, now let's start this Date Difference tutorial! 1. Let's start with creating a Windows Form Application for this tutorial by following the following steps in Microsoft Visual Studio: Go to File, click New Project, and choose Windows Application. 2. Next, add two DateTimePicker named DateTimePicker1 and DateTimePicker2 in the ToolBox. Then add a button named Button1 labeled as "Compute Date Difference". Take note that you have to place DateTimePicker2 above DatePicker1. You must design your layout like this: 3. Now, put this code in Button1_Click. This will display the result of the DateDifference from the two DateTimePicker.

Explanation:

firstDate variable holds the value of DateTimePicker1 and secondDate variable holds the value of DateTimePicker2 as Date. Dim diff2 As String = (secondDate - firstDate).TotalDays.ToString() - this is the main syntax of this tutorial that computes the date difference between the two DateTimePicker. The variable diff2 holds the Date Difference between the secondDate and the FirstDate with their total days to minus. Then after being subtracted it is now converted into string. Then it will display the Date Difference of the two DateTimePicker.
