Re: getting number of items from curr playlist of windows media player

Maybe beacuse the code in MainForm_Load cannot find specified window?
There can be different reasons why this is happening:
- there is not such window ( check windows with Spy++ tool )
- bug in the Win32 class

Also you do not check if
wnd = Win32.FindWindow("WMPlayerApp","Windows Media Player");
returned valid wnd handle.
