might not be the best way to do it, but this is one way:
Imports System.Timers
Public Class Form1
Private Delegate Sub ScrollText()
Private moTimer As Timer
Private moDelegate As ScrollText = New ScrollText(AddressOf MoveIt)
Private Sub Form1_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
moTimer.Stop()
moTimer.Dispose()
moTimer = Nothing
End Sub
Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Me.Text = "this is a test of the scrolling feature. "
moTimer = New Timer(500)
moTimer.AutoReset = True
AddHandler moTimer.Elapsed, AddressOf Timer_Event
moTimer.Start()
End Sub
Private Sub MoveIt()
Me.Text = Mid(Me.Text, 2, Me.Text.Length) & Mid(Me.Text, 1, 1)
End Sub
Private Sub Timer_Event(ByVal sende As Object, ByVal e As System.Timers.ElapsedEventArgs)
Me.Invoke(moDelegate)
End Sub
End Class

Hi Friends,
Please give me the answer of my question :
My question is :
What is the difference between Leave and LostFocus events of textbox in vb.net? When I move the focus of textbox1 to textbox2 then the error will occur. Please see following code. Run it and give me the positive reply. It's urgent....
Program Code 1 of Lostfocus Event. But It gives error and not properly run :-
Public Class Form1
Private Sub TextBox1_LostFocus(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox1.LostFocus
If TextBox1.Text = "" Then
MsgBox("enter valid values in textbox1")
End If
End Sub
Private Sub TextBox2_LostFocus(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox2.LostFocus
If TextBox2.Text = "" Then
MsgBox("enter valid values in textbox2")
End If
End Sub
End Class
Program Code 2 of Leave Event. And it is properly run :-
Public Class Form1
Private Sub TextBox1_Leave(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox1.Leave
If TextBox1.Text = "" Then
MsgBox("enter valid values in textbox1")
End If
End Sub
Private Sub TextBox2_Leave(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox2.Leave
If TextBox2.Text = "" Then
MsgBox("enter valid values in textbox2")
End If
End Sub
End Class
Give me the difference between these two event after studying it.
Please Help Me......
I am waiting for your answer!!!!!!!!!!!!
Thanks,
Bye.

Major Difference is in the order of occurance
Mouse and Keyboard Event fires Leave and LostFocus Event differently
Mouse first has lostfocus and then Leave
Whereas Keyboard fires Leave event first and then LostFocus
Primarily LostFocus is Mouse Event
Point To Note : Microsoft has recommended not to use LostFocus Event and you may not find LostFocus event in future versions
so please dont get with lostfocus anywhere in your code

Hi.
I have my printing method working well, but i need some advice as to how i can get the last page number so i can draw (drawstring) something only on last page.
for example. i have total pages of 3. i want to be able to make sure that when page 3 is drawing that i could also add another drawstring only for that page.
i hope i've been able to relay what i need to accomplish.
Many Thanks

Then why try and contact him like this. To me, this type of post is an attempt at inducing guilt in order to get a response.

Then why don't you post it as a reply to the post he made asking you to do this.

And that allows you to spam the forums? Learn some patience.
The people who answer questions here do so becuase they want to help. They don't want to be guilt-tripped into helping (and this thread is a classic example) they just want to help. If the situation is urgent then I suggest that you take out a support incident with Microsoft. I'm sure they'll help you with your problem for a small fee. But if you post here then, or on any other free forum, then the individual's free time is usually the primay dictating factor to whether you get help or not.

Hi,
previously i worked on VB. i know onerror, onerror goto label, and onerror Resume next statements.
now i want to learn VB.net.
i am little bit confused( ) with this Try-catch blocks mechanism.
TRy
code
----
----
----
catch exceptionmanager.Publish(ex)-----? means we are displaying error message to USER? is it user defined message or system generated message?
Finally..........> in finally block what we have to write?
please can anyone tell me this mechanism. which site is good to refer this concept??
Thanks,
Rahi

If you like, but rarely. It usually means you anticipated a specific type of error. Your syntax is wrong. Catch can catch Exception, but it should really catch specific exceptions such as
catch(FileNotFoundException ex) -- this is C# syntax, it probably gets twisted a little for VB
So, you'd catch this if you knew there was a chance it would be thrown, and you know how to deal with it, for example, by showing a message, or creating a config file that is missing.
Rahithi wrote: n finally block what we have to write?
Any code that you want executed if an exception is thrown or not, such as code to close a database connection or clean up resources.

Try this:
Try<br />
'Code...etc<br />
Catch ex as exception<br />
messagebox.show(ex.message)<br />
end try
you can change it to try finally statment or whatever.
