You can handle a selected index changed event. How you handle it depends on if you want to write your record again for every field that changes, or if you want a save button.

Yes, it's possible, but only if the mother board supports it. Unless the mother board is willing to turn itself on, it's not really possible. Doing it via VB.NET will only work if the code is running on another machine, and the machine being switched on has mother board features that your code can access.

Unless your code drives a robot that pushes the power button.

Resolution Problem Pls Help

Some motherboards have wake on LAN, I'd expect those can be started with LAN activity. No, I have no code, I think it's a wild goose chase in most cases.

Try docking your controls so that they maintain equal amount of form space.

Trinity: Neo... nobody has ever done this before.
Neo: That's why it's going to work.

You need to set the anchor property on your controls, so they size themselves automatically.

You would use the DateTime.Subtract method.

Dim StartDate As New System.DateTime(2007, 6, 11, 12, 0, 0)
Dim EndDate As New System.DateTime(2007, 7, 12, 12, 0, 0)

Dim TotalDate As System.TimeSpan
TotalDate = EndDate.Subtract(StartDate)
MsgBox(TotalDate.TotalDays & "Days Left")

Trinity: Neo... nobody has ever done this before.
Neo: That's why it's going to work.

Socheat.Net11-Jun-07 17:37

11-Jun-07 17:37

I get an error.
Type "System.TimeSpanTotalDate" is not defined.

So what can i do?

It should work. Could you please post your code?

Socheat.Net11-Jun-07 17:51

11-Jun-07 17:51

It work now.

Dim StartDate As New System.DateTime(2007, 6, 11, 12, 0, 0)
Dim EndDate As New System.DateTime(2007, 7, 7, 12, 0, 0)
Dim TotalDate As System.TimeSpan = EndDate.Subtract(StartDate)
response.Write(TotalDate.TotalDays & " days left")

By the way I want to get day and time left like N7W "24 days nad 2hours left"

substituting minutes, seconds, days, or whatever interval you are looking for in the place of 'hours'. Well, in Visual Basic .NET there are two main ways to achieve this result; the DateDiff function or through the TimeSpan structure.

Both of these methods are equally valid, where they overlap in functionality, but each of them has a couple of unique features. Despite their similar functions, the core difference between the two is that DateDiff is a function, so you need to call it every time you need to retrieve a value, whereas TimeSpan is a structure that is created once and then you just work with its various members as needed.

Using DateDiff, you call it with different date interval parameters to retrieve the appropriate value:

Dim D1, D2 As Date
D1 = Date.Now
D2 = 11/9/2007 'DateDiff
Console.WriteLine("DateDiff")
Console.WriteLine()
Console.WriteLine("{0} Days", _DateDiff(DateInterval.Day, D1, D2))
Console.WriteLine("{0} Hours", _DateDiff(DateInterval.Hour, D1, D2))
Console.WriteLine("{0} Minutes", _DateDiff(DateInterval.Minute, D1, D2))
Console.WriteLine("{0} Seconds", _DateDiff(DateInterval.Second, D1, D2))
Console.WriteLine()

Hope this code will Help you.
