DateTimePicker Help

[veedubdan74]

Hello, I'm trying to create some code that will take the date from one DateTimePicker (arrival date) and subtract it from another DateTimePicker(departure date) to determine the time stayed (hotel application). I also have to determine if, and how many days, are during the weekend (higher price).. and if the date is anytime May - September. This is for a college class, but my book doesn't really explain any of this, so any help would be greatly appreciated

I also know some people want some sort of code so they aren't doing everything, but I haven't run into DateTimePicker yet so I have no clue what I'm doing, so even a website that explains how to do various functions with it would help

Thanks in advance
Dan

Edit: I'm using Visual Studio 2008 Express, so i believe this is the right thread =x

Here's VB6 and Earlier Forum
Your problem isn't to take the date from a control

Dim MyDate As Date

MyDate = DTPicker1.Value

My advise is that You should read (a little) about Date Functions, they are easy and there are a lot of samples about them in the web, such as :

Actually you missed it... you posted in the VB6 area... you want the .NET area... I'll let someone know it needs to be moved.

At anyrate, the DTP has a .Value property that will get you the date selected.

Had this been really for VB6, I would have then pointed you at the DateDiff function... but that won't do any good.

In .Net, you can actually do it like this:

Dim date1 As Date = CDate("1/1/2009")
Dim date2 As Date = CDate("12/31/2009")

Dim diff As TimeSpan = date2.Subtract(date1)

The TimeSpan object will then contain all of the info you need. There are a number of properties in there that will return the difference in hours, minutes, days, months, weeks and so on, poke around, look it up on MSDN and see what fits for you.

Just one small point. Since .NET 2.0 the DateTime structure has supported arithmetic so you don't actually need to use the Subtract method. You can use the more natural subtraction operator:

Dim diff As TimeSpan = date2 - date1

Ooohh... that's right, I keep forgeting that the operators have been overloaded for dates. ;P
