            MsgBox("ERROR: Max Boot Time 90 Secounds", MsgBoxStyle.Exclamation)
        Else
            Dim i As Integer = 0
            For Each item In ListBox1.Items
                 Dim request1 As WebRequest = WebRequest.Create(ListBox1.Items(i) + "?act=phptools&host=" + TextBox1.Text + "&time=" + TextBox2.Text)
                i = i + 1
            Next item
        End If
    End Sub

I don't understand VB.NET, .Text is implying it's text, Yet the 90 is obviously a dec number.
And even if the logic existed, you are not ++ing the textbox, So how does your limit work?


[QUOTE=jokjok123;12455767]i = i + 1[/QUOTE]

you can do i++ or i += 1. lol


And you need to be more specific with what doesn't work.

VB.NET supports implicit type conversion

In this code he's not using any "Option Strict Off", so he's right: he needs to secern strings from integers, which is also the most safe thing to do.
 jokjok123 you are never employing a request: you are doing an initialization of the WebRequest class with a WebRequest.Create, but you don't even take profit on it with a WebRequest.GetResponse() (https://msdn.microsoft.com/en-us/library/system.net.webrequest.getresponse(v=vs.110).aspx):
[quote]The GetResponse method sends a request to an Internet resource and returns a WebResponse instance. If the request has already been initiated by a call to GetRequestStream, the GetResponse method completes the request and returns any response.[/quote]

Make sure these backdoor shells are worth and that they do actually get the data you are channelizing by those variable fields you are passing, otherwise it won't succeed.

VB.NET doesn't support i++, i += 1 will work though.
Go ahead and directly cast that 90 to a str.

If HuraTextBox2.Text > CStr(90) Then

Which is wrong, because you are ordering lexicographically (https://en.wikipedia.org/wiki/Lexicographical_order). In that order:

Dim num As String = "99"
        
            If num > CStr(100) Then
                Console.WriteLine("greater")
            End If

this code would print "greater", when it is not - because the first character of converted string '1' is lower than the first character of num, '9'. The only correct is to just parse the TextBox's text to an integer, and then do the comparison.

I totally meant:

If CInt(HuraTextBox2.Text) > 90 Then

Sorry about that.
