It would be easier to help, if you specify what kind of problem you are facing. Tell us what your doing with the code and what is the error or problem you are facing with the data.
You can use the Date.Timespan class to get the difference between two dates and use a timer control to do what you want.

Thanks for the information. I will try and utilise the Date.Timespan class instead of the Date.Interval class, and hopefully i will make some headway.
Many Thanks.

You could display "Now" and then set the timer event to update the textbox/label and set the timer interval to 1000 milliseconds (1 second).
Here is a sample
Dim d As Date
Dim ts As TimeSpan
Private Sub TimerTick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
d = #12/25/2007#
ts = d.Subtract(Now)
Label1.Text = ts.ToString
End Sub
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Load
Timer1.Interval = 1000
Timer1.Enabled = True
End Sub

Hey thanks for your help, you've got me sorted and it works a treat. I can now start getting this implemented into my application.

Could i ask another question which really is about syntax. What if i want to put a date and time into d, would that then be #12/25/2000/12.45#.
I'm presuming this isn't correct?

Care to explain the problem or error you're getting?

Show us your VB.NET code and we'll see what we can do to help you. We won't write it for you.

i Upgrade my vb 6.0 application to Vb 2005 it works fine in vb 6.0 but not in vb.nET.
Now the problem is solved actually it makes problem in passing structure without marshalling.
Thanks
Thanks

I'm glad it's working. From the samepl you provided from the conversion, you could have done all of this in one line of code if you rewrote it from scratch.

are you *sure* it's a COM dll ?

How to get all window handles knowing it's process name?
|
|
|
|
|
Use the Process class and it's GetProcessesByName method to get the Process object for it. There is a MainWindowHandle property in that object. You use that handle and the Win32 API function EnumChildWindows[^] to get all of the child window handles and add them to your list. You then have to use EnumChildWindows again on each of those returned handles to get the child windows of that list of child windows, again, adding the new handles to the same list you're maintaining. Rinse and Repeat until you get to the end of your handle list.

Thanks, works like a charm... But i've got another question. I am trying to use FindWindowEx function to get a handle of the control i need, but i do not have a class name for that control. enumerating is stupid, i'd like to hard code it. Is there a way to know the class name?

I have a non-fullscreen and non-maximised program with a timer control that ticks over every 20 seconds performin a check on the time and comparing it to another time. It's function is irrelavent, thr problem i am having is that whenever the timer ticks over and the desktop (i.e. icons and taskbar) is visible, all the icons flash briefley and refresh. Is it possible to stop this desktop refresh when the timer ticks over.

What the code u r writing?

There is no way that a timer which does a compare of times, can cause your desktop to refresh, there's something you're not telling us.

Christian is correct. The Timer doesn't make the desktop repaint. Something else in your code is causing it.
|
|
|
|

I can't see anyway it's causing this refresh thing, but every 20 seconds (what the timer is set to) it does it, all the icons flash.
I'll post some of it:
If DateDiff(DateInterval.Day, d1, d2) = My.Settings.ChangeValue Then<br />
If My.Settings.ChangeMode = 0 Then<br />
Index = RandomClass.Next(-1, Me.ImagesComboBox.Items.Count + 1)<br />
If UsedList.Count = Me.ImagesComboBox.Items.Count Then<br />
UsedList.Clear()<br />
End If<br />
Do Until UsedList.Contains(Me.ImagesComboBox.Items.Item(Index)) = False<br />
Index = RandomClass.Next(-1, Me.ImagesComboBox.Items.Count + 1)<br />
Loop<br />
My.Settings.Index = Index<br />
path = Folder & "\" & Me.ImagesComboBox.Items(Index)<br />
If Not path.Remove(0, path.IndexOf(".")) = ".bmp" Then<br />
Dim image As Image = image.FromFile(path)<br />
image.Save(path.Remove(path.IndexOf("."), path.Length - path.IndexOf(".")), Imaging.ImageFormat.Bmp)<br />
My.Settings.WasSavedAs = True<br />
path = path.Replace(path.Remove(0, path.IndexOf(".")), ".bmp")<br />
End If<br />
Else<br />
If My.Settings.WasSavedAs = True Then<br />
Index = My.Settings.Index + 2<br />
Else<br />
Index = My.Settings.Index + 1<br />
End If<br />
path = Folder & "\" & Me.ImagesComboBox.Items(Index)<br />
If Not path.Remove(0, path.IndexOf(".")) = ".bmp" Then<br />
Dim image As Image = image.FromFile(path)<br />
image.Save(path.Remove(path.IndexOf("."), path.Length - path.IndexOf(".")), Imaging.ImageFormat.Bmp)<br />
My.Settings.WasSavedAs = True<br />
path = path.Replace(path.Remove(0, path.IndexOf(".")), ".bmp")<br />
End If<br />
End If<br />
End If

I need to read the contents of a file that is located in the internet. The problem is that this file is located in a folder that needs username "ukkeli" and password "hattu123". I'm using the code below:
Dim myWebClient As New System.Net.WebClient 'the webclient
Dim file As New System.IO.StreamReader(myWebClient.OpenRead("http://www.examplesite.com/subdir/file.txt"))
Dim Contents As String = file.ReadToEnd()
file.Close()
How can I make the application to give the needed username and password automatically?

it might be HTTP authentication. Try that.

I've told you three times what you have to do.
I give up. You're simply not listening, or your not doing any experimentation to test what I'm telling you.
If you don't put the effort into it, why should we?
[EDIT]
Wait a minute! Sorry! My bad. I thought you were asking the same question for a fourth time. 
You don't need all of this:
With ComNum_key
.ActiveConnection = conn
.CommandText = "prcInserting"
.CommandType = adCmdStoredProc
End With
With ComExtension
.ActiveConnection = conn
.CommandText = "prcInserting"
.CommandType = adCmdStoredProc
End With
With ComCell_ID
.ActiveConnection = conn
.CommandText = "prcInserting"
.CommandType = adCmdStoredProc
End With
With ComActual_Extent
.ActiveConnection = conn
.CommandText = "prcInserting"
.CommandType = adCmdStoredProc
End With
With ComLis_key
.ActiveConnection = conn
.CommandText = "prcInserting"
.CommandType = adCmdStoredProc
End With
With ComFunc_key
.ActiveConnection = conn
.CommandText = "prcInserting"
.CommandType = adCmdStoredProc
End With
You're creating 6 seperate sql commands and adding a single parameter to each. You need to create just ONE sql command, then add all 6 of your parameters to the one command. Also, you've managed to convert the input from the textboxs to numbers, but you didn't use these numbers in the sql parameters. You, AGAIN, assigned the strings to the parameters. (This is why I thought you asked the same question for a forth time!) Those are really BAD variable names BTW.
strNum_key = Val(Trim(txtnumkey.Text))
strExtension = Val(Trim(txtextension.Text))
strCell_ID = Val(Trim(txtcellid.Text))
strActual_Extent = Val(Trim(txtactualextent.Text))
strLis_key = Val(Trim(txtliskey.Text))
strFunc_key = Val(Trim(txtfunckey.Text))
Set sqlCommand = New Command
Set prmNum_key = sqlCommand.CreateParameter("Num_Key", adBigInt _
, adParamInput, strNum_key )
Set prmExtension = sqlCommand.CreateParameter("Extension", adBSTR _
, adParamInput, , strExtension)
Set prmCell_ID = sqlCommand.CreateParameter("Cell_ID", adBSTR _
, adParamInput, , strCell_ID)
Set prmActual_Extent = sqlCommand.CreateParameter("Actual_Extent", adBSTR _
, adParamInput, , strActual_Extent)
Set prmLis_key = sqlCommand.CreateParameter("Lis_Key", adBSTR _

Set prmFunc_key = sqlCommand.CreateParameter("Func_key", adBSTR _
