I am trying to make a simple calculator program but when I build the code an error come up (BC30737) saying 'No accessible 'Main' method with and appropriate signature was found in 'Module1' and I have no clue what so ever on what is causing it or how to fix it.
It's not very good code but I was just wondering how to make it work!
Module Module1
Public Sub Main(needsWeclome As Boolean)
'See's if the user needs the copyright notice or not.
If needsWeclome = True Then
'Says welcome back to the user.
Console.WriteLine("Welcome Back")
Console.WriteLine(" ")
'Skips copyright notice.
GoTo Restart
End If
Call Introduction()
Restart:
Call MethordOfCalc()
Call PlayAgain()
Console.ReadLine()
End Sub
Sub Introduction()
'Legal stuff!
Console.WriteLine("The Calaculator!")
Console.WriteLine("(C) Copyright James Robinson 2017")
Console.WriteLine("All rights reserved.")
'Introduction and asking the user for there prefered method of calculation.
Console.WriteLine("What is your prefered methord of the calcultions!")
End Sub

Console.WriteLine("3. Multiply 7. Modulous") 'Check Spelling of 7.
Console.WriteLine("4. Divide 8. W.I.P xRoot")
Console.WriteLine()

Thanks for the help
You changed the parameters list of the Main() method into:
Public Sub Main(needsWeclome) As Boolean
But Main() is expected to have certain fixed set of parameters, you cannot change them.
If you are not sure how to revert it to previous form, just create a temporary new project of the same type and take original header of Main() from there.
