System.Windows.Forms.Keys.HasFlag behaving weirdly

Question

I have the following code, meant to prevent user from writing new-lines in a memo text editor:

private void m_commentMemoEdit_KeyDown(object sender, KeyEvent         


        

Answer 1

HasFlag is for Flags - which means if a bit is set or not

the keyvalue is an ordinal value, so completely different from flags use the comparison operator and everything should be fine.

some enum fields are defined like flags, e.g.

enum SomeFlag
{
   BitOne = 1, 
   BitTwo = 2, 
   Bitthree = 4
};

here it makes sense to use "HasFlag"
