Re: How to add clock timer to listview column in vb6?

10-May-07 7:36

could any one show me how i can add clock timer that shows hour:min:seconds to a perticuler listview column ?
I want to add running time as a listview -item.

I have seen applications that they added timer to listview item and ability to freez it or reset it when diffrent events happens. There are a few other columns in my listview too. So i want add running timer to 3th column.I hope there be a solution that doesn't disturb the focous .

I want to add this running timer in the 3th column of a row that i specify. Not all rows at once.So by default other rows i want it to have - and when i decide for example add running time to row 3 then it be added.I want to have the abiliy to freez the time when i want or remote it.

add the timer control your form
set the interval to 1000
in the event routine, use the keyword 'now' and format it to be hh:nn:ss and keep replacing the value of the cell with the result

Thanks for you reply. could show me how to add 'now' and format it to be hh:nn:ss ...

I am adding item to listview like this :
ListView1.ListItems(1).ListSubItems(3).Text = "changed2"

so how to add running time instead of change2? Do you think using this method will make the listview reload every seconds? i hope that is not the case since it will disturb form focus. I have seen applications that they add running time to listview column without any listview reload every seconds .

vb6 - format(now,"hh:nn:ss")
vb.net - now.tostring("hh:mm:ss")

Thanks for you reply. I tried the following and it only display the current time!! I wanted to start from 00:00:00 and start running

ListView1.ListItems(1).ListSubItems(4).Text = Format(Now, "hh:nn:ss")

make a module level variable that will hold to the current ticks

private mStartDate As Double = Now.Ticks

in the timer event routine

Dim s As String = TimeSpan.FromTicks(Now.Ticks - mStartDate).ToString
ListView1.ListItems(1).ListSubItems(4).Text = s.Substring(0, s.IndexOf("."))

I placed "private mStartDate As Double = Now.Ticks: inside a module.

Then i added timer to the form an set its interval to 1000.Then i added following code:

<br />
Private Sub Form_Load()<br />
<br />
    <br />
     Timer2.Interval = 1000 ' <-- 10 seconds<br />
    Timer2.Enabled = True<br />
End Sub<br />
<br />
Private Sub Timer2_Timer()<br />
Static lngMin As Long<br />
<br />
    lngMin = lngMin + 1<br />
    <br />
    'every 2nd timer tick reload the listview<br />
    If lngMin Mod 2 Then<br />
      <br />
        Dim s As String = TimeSpan.FromTicks(Now.Ticks - mStartDate).ToString<br />
ListView1.ListItems(1).ListSubItems(4).Text = s.Substring(0, s.IndexOf("."))<br />
<br />
    End If<br />
<br />
End Sub<br />
<br />

then i get compile error :

Expected: end of statement

pointing at:

private mStartDate As Double = Now.Ticks

Many thanks for trying to help me Smile | :)

. I am working on vb6 for this project. VB6 has listviews by selecting Microsoft windows common controls 6.0(sp6) component. I have seen a few applications not sure what programing language they are written it .They add timer to listview without noticing any flicker or reload!!

***make a module level variable***

private mStart as single

***in the load event of the form***

mStart = Timer

***in the timer event routine***

ListView1.ListItems(1).ListSubItems(4).Text = Format(TimeSerial(0, 0, cint(Timer - mStart), "hh:nn:ss")

You can either write this function yourself, the math is very easy, or you can use the TimeSpan class to do it for you.

Dim x As New TimeSpan(0, 0, 0, 0, milliseconds)
Console.WriteLine("Minutes: " & x.Minutes)
Console.WriteLine("Seconds: " & x.Seconds)
