How to open multiple IE? (Visual Studio 2008) (multithreading)

[darcee]

what i did was i use a select statement in opening multiple IE just for testing but the main function is what you put number on a textbox then the number the IE's will open for example i put 100 on textbox then when i click a button then 100 IE's will open so if im going to use select statement when opening 100 IE my code will be crazy... heres my sample code..

   
      Private Sub btnGenerate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnGenerate.Click
   
      Dim num As Double
   
      Try
   
      num = txtNoOfMulti.Text
   
       
   
      Catch ex As Exception
   
      MsgBox("You Must Enter a Number", MsgBoxStyle.Exclamation)
   
      End Try
   
       
        Select Case num
  
       
  
      Case "1"
  
      System.Diagnostics.Process.Start("iexplore", "www.mail.yahoo.com")
  
      Case "2"
  
      System.Diagnostics.Process.Start("iexplore", "www.mail.yahoo.com")
  
      System.Diagnostics.Process.Start("iexplore", "www.mail.yahoo.com")
  
      Case "3"
  
      System.Diagnostics.Process.Start("iexplore", "www.mail.yahoo.com")
  
      System.Diagnostics.Process.Start("iexplore", "www.mail.yahoo.com")
  
      System.Diagnostics.Process.Start("iexplore", "www.mail.yahoo.com")
  
      Case "4"
  
      System.Diagnostics.Process.Start("iexplore", "www.mail.yahoo.com")
  
      System.Diagnostics.Process.Start("iexplore", "www.mail.yahoo.com")
  
      System.Diagnostics.Process.Start("iexplore", "www.mail.yahoo.com")
  
      System.Diagnostics.Process.Start("iexplore", "www.mail.yahoo.com")
  
      Case "5"
  
      System.Diagnostics.Process.Start("iexplore", "www.mail.yahoo.com")
  
      System.Diagnostics.Process.Start("iexplore", "www.mail.yahoo.com")
  
      System.Diagnostics.Process.Start("iexplore", "www.mail.yahoo.com")
  
      System.Diagnostics.Process.Start("iexplore", "www.mail.yahoo.com")
  
      System.Diagnostics.Process.Start("iexplore", "www.mail.yahoo.com")
  
      End Select
  
       
  
      End Sub

How do you usually do the same thing multiple times? With a loop. What type of loop is best for doing something a specific number of times? A For loop.

i try the loop for this and for loop but the IE never stops poping... i think its a if else statement but i dont why... i think its something like this but i dont know the exact code

 dim x as integer

x =  System.Diagnostics.Process.Start("iexplore", "www.mail.yahoo.com")

Process.Start doesn't return an Integer. There's no use for an If...Else statement because that specifically tests a condition and does one thing if it's True and another if it's False, which is not what you want to do. A For loop is specifically for performing an action a specific number of times, which is what you want to do. Maybe you should show us your attempt at a For loop and we can help you fix it.

im sorry but i dont have any idea.... please give me an idea.... on how to solve this.... thx in advance...

A For loop is one of the basic building blocks of VB.NET programming. If you have no idea how to use them then I suggest that you find yourself a tutorial and work through it to get the basics down before you try more adventurous things.
