one of those days ....

It must be hot or I'm having one of those days. I was just testing some code and it seemed to do the unexpected. The problem was I had written :
Public Overrides ReadOnly Property IsInvalid() As Boolean
Me.handle = IntPtr.Zero
This function was not only returning the wrong value but it was also changing the state !!
Okay, obviously I meant that to read:
Return Me.handle = IntPtr.Zero
but I made a mistake. The problem was exasperated by no warning from VB that the Get wasn't returning a value. I hate that. It's as bad as that stupid implicit local variable VB creates for you with the same name of the function. I wish I could easily turn off VB's desire to help me as that would be in fact far more helpful ;)
And of course if there was an option to have a different equality operator from an assignment operator, that would have possibly helped a little in this case. Maybe I should write it using the double negative:
Return Not (Me.handle <> IntPtr.Zero)
