System.Char.IsLower() is a static method, requiring that you pass in the
character you want to know about. The code you posted always passes the
same character to the method (the character generated by converting the
non-character value of Keys.A to a character), and so will always have
the same result.
Try instead:
If System.Char.IsLower(e.KeyChar) Then
MsgBox("a")
Else
MsgBox("A")
End If
Note that had you tried to write that code in C#, the compiler would
have refused to let you call the static method as an instance method.
VB.NET works great for a lot of things, but if you're going to use it,
it's worth remembering that the language is a lot more flexible in
certain ways and can allow you to write code that isn't literally doing
what it might look to the human reader that it's doing.
