I'm working on a program for reading a txt file. the file is read and its data are sent to the viewers with an indeterminate cycle every minute.
I wanted to replace the sleep with a timer. I tried the same procedure under timers instead of under button1 but it does not work. how can I proceed with the change.

Me.Size = Screen.PrimaryS creen.WorkingAr ea.Size
Me.Location = Screen.PrimaryS creen.WorkingAr ea.Location
End Sub
Private Sub Button1_Click(B yVal sender As Object, ByVal e As System.EventArg s) Handles Button1.Click
Button1.BackCol or = Color.Red
Dim riga1 As String
Dim i As Integer
Do
leggi1 = disco1.OpenText ("e:\rgb100.txt ")
For i = 1 To 60
i = i + 1

Do I need to use flock() when reading a file into an array? It's possible that
the file in question could be open at the time the file('filename') request is
made. I realize flock() is required when opening a file with fopen() when there
is contention for the file:
$fp=fopen($ctr, 'w');
//only write if we can get lock on file
if (flock($fp, LOCK_EX))
{
fwrite($fp, "0");

Greetings,
I need to read (unformatted text) from stdin up to EOF into a char
buffer; of course I cannot allocate my buffer until I know how much
text is available, and I do not know how much text is available until I
have read it... which seems to imply that multiple reads of the input
stream will be inevitable.
Now I can correctly find the number of characters available by:

Hi all,
I am new to asp.net (learning phase).
I have to develop application in asp.net to read file from client pc
and display statistics of that file to client.
So my question is that to read file from client pc do i need to upload

Is it possible to read a CSV from the Client, and bind my Datagrid to the

I have tried and in Debug mode on my workstation it works fine, but when I

Has anyone done this before? If so, how do I do it? I'm new to ASP.net so
