Syntax for finding time difference?

[andru]

Hey guys, I'm new to VB.NET and really unfamiliar with the syntax.

I made one button, so when it's clicked, variable:

StartTime = Now

 

Similarly, another button when clicked is:

EndTime = Now

 

How do I find the elapsed time? i.e.

ElapsedTime = EndTime - StartTime?

 

I get the msg "Operator is not valid for type 'Date' and 'Date'."

 

Help this newbie with such a simple question please! :(

Dim startTime As Date = Date.Now
Dim endTime As Date

do something here
Dim i As Integer
For i = 1 To 10000
       Application.DoEvents()
Next
endTime = Date.Now

Dim diff As TimeSpan = endTime.Subtract(startTime)

MessageBox.Show(diff.TotalSeconds.ToString)

Thanks, but how I get it into hh:mm:ss format?

Not near VS.Net at the moment so I may be wrong but I thing the DateTime class can be created from a TimeSpan (I think it is one of the overload new methods).

 

Doing that will allow you to then use the dates .ToLongTime method.
