I wouldn't use a txt file to store the 50$. Use a file in random access mode. That may be even enough security for you if you store more than just the dollar value.

a possibility (not very safe, but it works) is:
put two buttons and three textboxes on a form

Private Sub Command1_Click()
Text2.Text = 11111111 Xor Int(Text1.Text)
End Sub

Private Sub Command2_Click()
Text3.Text = 11111111 Xor Int(Text2.Text)
End Sub

when you run the program you can write a number to the first textbox and encryt it with button one to textbox2 and decrypt it to txtbox3. This is not a very good method. It works only with integers and not work with high values.
Of course you can change the 1111111 to any number consisting of "1" and "0".

Do you want to set your form maximized?
just put Me.WindowState = vbMaximized

I hope I could help a little.
