Help, get system time with milliseconds without Timer control

[jeffbroodwar]

please help me get the system's time (with milliseconds) i need it to calculate the Soap request and response time in my SOAP project. i tried to use timer but the problem is, whenever i'm invoking a method.... the timer gets stuck along with the process, meaning it always returns .01 millisecond.... .. timer hangs with my pc..... i need to get the system time (with milliseconds) before and after calling the webservice then compute for the difference..... PLEASE HELP ME GUYS THIS THING'S IMPORTANT TO ME !! Thanx a lot !!!!!

use Format(Now, "HH:mm:ss:m s")

use Format(Now, "HH:mm:ss:m s")

sorry, the above post is worng

guess so.... but why? i mean it goes with vb's format function right? why will it be wrong???... hmm... can you test the code that i've posted? perhaps you can help me decide what's the correct one.... and please explain to me why your post is wrong. i tested it, it's obviously wrong but what made it wrong? thanx....

no, i told the post which i had post is wrong

use Format(Now, "HH:mm:ss:m s")

Format(Now, "HH:mm:ss:m s")

is incorrect..... for some reason the ms is not reconised by visual basic...
I've not had time to look into it, but do simple test

Private Sub Command1_Click()
MsgBox Format(Now, "HH:mm:ss:ms")
End Sub

you will see the last 3 digits are actully seconds.....
my is "3" then the current seconds digit(s)

the API GetSytemTime Works best for current system time.... API's are always preffered

Hope this is what you wanted:

Public Sub DoWork()
     Dim startDt as Date = Now()

     ' Do you work here

     Dim endDt as Date = Now()
 
     Dim tm as long = DateDiffMs(startDt, endDt)
    
  End Sub


  Public Shared Function DateDiffMs(ByVal startDt As Date, ByVal endDt As Date) As Long
    Dim ms As Long = DateDiff(DateInterval.Second, startDt, endDt) * 1000
    If (endDt.Millisecond - startDt.Millisecond) < 0 Then
      ms += 1000 - (startDt.Millisecond - endDt.Millisecond)
    Else
      ms += (endDt.Millisecond - startDt.Millisecond)
    End If
    Return ms
  End Function

Cheers!

    Else
      ms += (endDt.Millisecond - startDt.Millisecond)
    End If
    Return ms
  End Function

This actually works. I have been looking for a solution to this sort of problem for some time. Funny that I never came across the "Date.Milliseco nd" bit, it was there all the time...

Thanks very much.
