Using TimeSpan or Elapsed e.t.c. Methods

[Kenneth P]

Hi,

I'm having a problem to measure the time between two events

Dim StrStart As DateTime = DateTime.Now.ToString("h:mm:ss.fff")
.... do some stuff ...
Dim StrEnd As DateTime = DateTime.Now.ToString("h:mm:ss.fff")
Dim Total As TimeSpan
Total = TmeSpan(StrEnd, StrStart) ' doesn't work
StrTotal = Total.ToString()
lblOut.Text = "Start: " & StrStart & " End: " & StrEnd

Any suggestions to the code or any ideas?

TIA

Hi Kenneth

Have a look at the DateTime.Subtract method :-)

Hi Philipp,

I did, and when I tried some code there I tried to response.write it and it
went well, but when I wanted to put the result of a timespan with the
Subtract method it says you cannot convert a timespan object into a string
object.

So I'm in a dead end.

Philipp,

Maybe I should give you some code I tried.

Dim starttime As DateTime
Dim endtime As DateTime
starttime = DateTime.Now
Dim diff1 As System.DateTime
.... doing some stuff....
endtime = DateTime.Now '("h:mm:ss.fff") trying with milliseconds, help?
diff1 = EndTime.Subtract(StartTime)
Response.Write(diff1) ' will work
lblTottime.Text = diff1 ' will not work

Any ideas on what to change in code to get the result into a label.text
property?

Kenneth,

If you write the TimeSpan, the output will be automatically converted
into a string - that's why it worked. However, assigning the TimeSpan to
the Text property of a Label does not work as the TimeSpan is a TimeSpan
and the property needs to get a string.

If the string output of Response.Write was ok for you, this should do:
lblTottime.Text = diff1.ToString()

Cheers,

Hi Philipp,

It just works great.

Thanks a lot.
