Ok, I take a look at this timer.
Thanks

Sorry but I don't know how to use this kind of timer in the way I need (property of an object).
Any other suggestions about how to make a System.Windows.Forms.Timer work as I need?

Thanks

Put a breakpoint in your timer tick event and see if it's being hit when you run it in debug. Does it hit the method or not? My suspicion is that it is hitting the method, but there's a bug in the if statement.

I put a breakpoint on line

If ((DateTime.Now.Ticks - mStartSession) > (CGlobali.WebSessionDuration * 10000000)) Then

but the debug never stop there

And if you set the breakpoint in SetWUser? Is it actually executing this line?

CType(CGlobali.Users.Item(i), CWebUser).WUTimer.Enabled = True

yes, the line is executed and the property WUTimer.Enabled is really set to true, to check it I wrote just after that line something like this:

Dim aaa As Boolean
aaa = CType(CGlobali.Users.Item(i), CWebUser).WUTimer.Enabled

and aaa become true.
It seems like the instruction

AddHandler (mWUTimer.Tick), AddressOf WUTimer_Tick

does not link the sub WUTimer_Tick to the event mWUTimer.Tick

Try changing your class so that it looks like this:

Public Class CWebUser
 
  Private mUserName As String = ""         'nome utente
  Private mPassword As String = ""         'MD5 della password 
  Private mIP As String = ""               'IP di provenienza della connessione
  Private mStartSession As Long = 0        'istante di inizio della connessione come ticks
  Private mLogged As Boolean = False       'flag per sapere se l'utente è loggato
  Private WithEvents mWUTimer As System.Windows.Forms.Timer   'timer per gestire la durata della connessione

  Sub New()
  End Sub
 
  Private Sub WUTimer_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs)
    If ((DateTime.Now.Ticks - mStartSession) > (CGlobali.WebSessionDuration * 10000000)) Then
      mWUTimer.Enabled = False
      mIP = ""
      mLogged = False
    End If
  End Sub
 
  Public Property UserName() As String
    Get
      Return mUserName
    End Get
    Set(ByVal value As String)
      mUserName = value
    End Set
  End Property
 
  Public Property Password() As String
    Get
      Return mPassword
    End Get
    Set(ByVal value As String)
      mPassword = value
    End Set
  End Property
 
  Public Property IP() As String
    Get
      Return mIP
    End Get
    Set(ByVal value As String)
      mIP = value
    End Set
  End Property
 
  Public Property StartSession() As Long
    Get
      Return mStartSession
    End Get
    Set(ByVal value As Long)
      mStartSession = value
    End Set
  End Property
 
  Public Property Logged() As Boolean
    Get
      Return mLogged
    End Get
    Set(ByVal value As Boolean)
      mLogged = value
    End Set
  End Property
 
  Public Property WUTimer() As System.Windows.Forms.Timer
    Get
      Return mWUTimer
    End Get
    Set(ByVal value As System.Windows.Forms.Timer)
      mWUTimer = value
    End Set
  End Property
 
  Public Sub EnableTimer(Byval IpAddress As String, ByVal Name As String)
    IP = IpAddress
    UserName = Name
    mWUTimer = New System.Windows.Forms.Timer()
    mWUTimer.Interval = 10000
    AddHandler (mWUTimer.Tick), AddressOf WUTimer_Tick
    mWUTimer.Enabled = True
  End Sub
End Class

Then call EnableTimer from your loop.

Thanks for your effort.
I did what you suggest but the result is the same: the tick event is not fired.

I fear it can be a problem related to thread.

The web server is a class with a thread that start the listener to receive connections from remote.
In the main thread of the application I instantiate an object WebServer and in this way I start its thread (the thread is created and started in the sub New() of the class).

The list of users (objects of the class CWebUser) is created in the main thread of the application.

The sub SetWUser(...) that enable the WUTimer is part of the class of the web server and is called by the function VerifyLogInData(...) called in the loop of the thread of the web server...

Is it possible that the problem is that I try to use from thread X a method of an object created in thread Y?

Re: [VB.NET 2008] A runtime created Timer doesn't work

23-Sep-13 4:51

Yes it is...
I have solved the problem enabling the timer from a sub in the main thread and colling this sub with the Invoke function from the web server thread.
Bye!

According to the documentation[^], that class isn't supported.

The Threading-timer[^] seems to be supported.

Hi Eddy, thanks for the replay.
Your link to the documentation about the System.Windows.Forms.Timer refers to .Net Framework 4.5 but, for this time, I'm luky and in Compact Framework 3.5 (and also .NET Framework 3.5) this timer is supported.

The System.Threading.Timer is supported, as Pete O'Hanlon suggested, but I have some problem to put one of this timer in my class as a property (I mean like I did with the Form.Timer).

Only for the member-listing; you can select the version with a dropdown at the top. The "version information" and "platform" heading isn't limited to .NET 4.5 - it simply lists where this class is supported.

Not according to MSDN.

I'm sure you're right but the page http://msdn.microsoft.com/en-us/library/system.windows.forms.timer%28v=vs.90%29.aspx[^]
is different from the page http://msdn.microsoft.com/en-us/library/system.windows.forms.timer%28v=vs.110%29.aspx[^]
and the Version Information at the bottom of the pages are different.

In my application I use some System.Windows.Forms.Timer and they work fine.
I will try not to make it known to MSDN...

am working on a word document Programmatically using C#.net, Interop.Word, I have paragraphs in this document starting and ending with a "#".

Example:

Once upon a time, there was a #little girl who lived in a village near the forest. Whenever she went out, the little girl wore a red riding cloak, so everyone in the village called her Little Red Riding Hood.#

One morning, Little Red Riding Hood #asked her mother if she could go to visit her grandmother as it had been awhile since they'd seen each other.#

"That's a good idea," her mother said. #So they packed a nice basket for Little Red Riding Hood to take to her grandmother.#

Now between all # I need the text be bold

Any HELP!!!

Thx Eddy, I know how to deal with word documents and ranges, my prob here is that I don't know the index of the characters #, plus that each 2 consecutive # make one range

You'd need to search for it.

When you find one, turn bold on. Find another, turn it off.

Hi,
I am trying to use RichTextBox to display a RTF file created by Microsoft Word.

I am using the

RichTextBox1.LoadFile(@"c:\test.rtf"); to load the data into the box.
Everything is fine except all the embedded graphics show up let justified.

The Word RTF file has them set to be behind the text and absolute positioned so there can be in middle of text field or where ever.

Is there a easy solution for this?

FWIW, it is a view for a help file that I wish to have icons and images included in.

Thanks in advance

Thanks, I just did not know if I was doing something wrong or what. I mean I am using Microsoft word with Microsoft .Net

I was hopeful that it was just a version issue, But apparently not.

The Web Viewer is doing a good job, I'll stick with that Smile | :)

The fact that both contain the word "Microsoft" does not imply that both should show exactly the same. Word isn't included in Windows, the RTF-control is simply a Windows-control - not something .NET specific. It displays RTF relative nicely, but it's not a WYSIWYG-editor. If it was as good as Words' editor-implementation, then it'd be quite easy to write a competitor.

Creative! Alternatively, you could automate Word and turn those documents into pictures. Not as good a solution as the web-viewer, since it'd result in small pictures on high-res screens and large pictures in low-res screens.
