If by encounter you mean "find" then you can use IndexOf(subString). If the substring is found it will return the index of where it was found, otherwise it will return -1. If you want anything more complex then you might want to look at regular expressions.

I want to make a program in VB.NET 2003 which will load 5 predetermine webpages in TabControl (5 Tab Pages), e.g:
http://www.yahoo.com
http://www.microsoft.com
http://www.abc.com
http://www.jkl.com
http://www.xyz.com
and will reload each of them in 30 seconds.
I made a program using Microsoft Web Browser (COM). But the problem is that on reload, it loads from Temporary Internet Files.
Please help me in making a program which will load 5 webpages at the same time and reload each of them from their server (not from Temporary Internet Files) every 30 seconds.

If you're using the COM component, there should be two Refresh methods, Refresh and Refresh2. Refresh2 will allow you to specify that the pagtes not be cached, or to ignore the cached page and reload from the server. You can find the contant values to pass into Refresh2 here[^].

I'm beginner for VB.NET. This is my code that migrating from VB to VB.NET. I'm selecting a group of data in the same data table from my MSSQL database to a dataset,and I wish to process the data row by row inside the dataset. There is no error shown when executed,but there is not messagebox pop-up to show the OriginatingAddress when I try to test the result.
Anyone can give me a solution about this please?
Private Sub Spam_Now()
Dim conStr1 As String
Dim con1 As SqlConnection
Dim reader As IDataReader
Dim sql1 As String
Dim command As SqlCommand
Try
con1 = New SqlConnection("server=(local);database=Jacson;integrated security=true;")
sql1 = "SELECT TOP 10 * FROM TT_Member WHERE Reminder ='0' AND Status ='1'"
command = New SqlCommand(sql1, con1)
con1.Open()
reader = command.ExecuteReader
If Not reader.Read() Then
Label1.Text = "Finished - " & DateTime.Now
Else
Do
Label1.Text = "Spamming - " & DateTime.Now
OriginatingAddress = reader.GetValue("Mobile_No")
MessageBox.Show("This is my>>" & OriginatingAddress & "<<") '<<<<
If OriginatingAddress.Substring(0, 3) = "601" Then
Telco = 2
ElseIf OriginatingAddress.Substring(0, 3) = "013" Then
Telco = 3
ElseIf OriginatingAddress.Substring(0, 3) = "016" Then
Telco = 6
ElseIf OriginatingAddress.Substring(0, 3) = "019" Then
Telco = 9
End If
Reminder_Msg = "Free Msg. Subscription Reminder.Fee:Auto renewal datedate,unless cancelled. To cancel, send STOP TT to 32132."
MT_Msg = Reminder_Msg
MT_Msg = Replace(MT_Msg, "datedate", Renewal_Date3)
Loop Until Not reader.Read()
con1.Close()
End If
Catch ex As Exception
End Try
End Sub

First, you declared your reader variable incorrectly. It should read:
Dim conStr1 As String
Dim con1 As SqlConnection
Dim reader As SqlDataReader
Dim sql1 As String
Dim command As SqlCommand
The second thing to check is if your SELECT statement is actually returning any rows. Are you sure this is a good query?

I am trying to write a program using the usb port on a computer to interface with another processor to collect data. I took a look at the ms comm in vb6 and all I see are the standard serial and parallel ports. Am I missing something or it not a feature of VB6

This isn't even a feature in the .NET Framework. Your comparing the USB port to a Serial or Parallel port. This is simply not how this port works.
USB communication is done through the device drivers for the device you're trying to communicate with. If that device exposes a simulated "serial" port, then you can use that to talk to it. If not, you'll have to consult some kind of SDK for the device in question.

how i'm going to renew my code

My application runs long and complex convertion, so i want to make it possible for the end-user to cancel this. However, as you may know, just placing a button does not help since any Visual Basic application is not able to let you use form elements while it is working.
How can i let the user cancel the process comfortably at any time?
|
|
|
|
|
Try this sample
Public Class Form1
Private bCancel as boolean
Private Sub DoLooping
While Not bCancel
Application.DoEvents()
'Do Something
End While
End Sub
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
bCancel = True
End Sub
' You can also use thread.
End Class

Cheesy poor man approach - use a timer or application.doevents to let the cancel button be clicked.
Better approach - do long-running processing on a background thread. Rocky Lhotka's article (link below) provides a straightforward approach for controlling a task and providing for user cancellation. You can have it implemented in 2 hours.

Could not find stored procedure 'DBAuthenticate'.
--> cmdSelect.ExecuteNonQuery()
|
|

It's telling you that your database doesn't have a stored procedure called "DBAuthenticate". Either you got the SP name wrong in your code, or you're not connected to the database you think you are when this call was made.

i got the DBAuthenticate function but still the same error appears.how can i made the connection?or test the connection is there?
|
|
|
|
|
If you get this error, your connection is being made successfully. There are still the problems that I mentioned, plus the possibility that your code is either using an SQL account or running under a Windows account that does not have the permissions to execute that stored procedure.
