Gives me this error:Conversion from string "asd" to type 'Boolean' is not valid.
Immediate window: A first chance exception of type 'System.InvalidCastException' occurred in Microsoft.VisualBasic.dll

If tb1.Text Or tb2.Text = "" Then
            MsgBox("Please input all fields", MsgBoxStyle.Critical + MsgBoxStyle.OkOnly, "Error")
        Else
            MkDir("C:\Windows\Accounts" + tb1.Text)
            Dim username As New System.IO.StreamWriter("C:\Windows\Accpimts" + tb1.Text + "\" + "username.txt")
            username.Write(tb1.Text)
            username.Close()
            Dim password As New System.IO.StreamWriter("C:\Windows\Accpimts" + tb1.Text + "\" + "password.txt")
            password.Write(tb1.Text)
            password.Close()
            MsgBox("Account Created", MsgBoxStyle.Information, "Accounts Created")
        End If
        Me.Hide()

        Form1.Show()
    End Sub

This line:

If tb1.Text Or tb2.Text = "" Then

Should be:

If tb1.Text = "" Or tb2.Text = "" Then
