Hi guys, many months ago I made a SQL Injection Finder, today I want to share you how to make it on VB.NET

Add a textbox and a button: 1 textbox where the user will be able to put the link; 1 button to check if the link is vulnerable
Before "Public Class Form1" you need to import this namespaces: System.Net, so:
Code:
Imports System.Net
Under the button code put this
Code:
    Function Check_SQL_Injection(ByVal daControllare As String)

      
        Dim SQLi As String
        Try

            SQLi = New WebClient().DownloadString(daControllare + "'")

            If SQLi.Contains("error") And SQLi.Contains("in your SQL syntax") Then
                MsgBox("Website vulnerable", vbInformation, "Information")

            Else
                MsgBox("Website not vulnerable!", vbInformation, "Information")
            End If
        Catch

            MsgBox("Website not vulnerable!", vbInformation, "Information")

        End Try



        Return daControllare
    End Function
On the button code put this
Check_SQL_Injection(TextBox1.Text)
Done.
