Hej!
Jag läser en introduktionskurs i spel-programmering,
http://msdn.microsoft.com/coding4fun/gamedevelopment/beginning/default.aspx,
och nu har jag ett problem:
När jag deklarerar funktionen
<code>
protected:
override void OnPaint(PaintEventArgs^ e)
{
this->Invalidate();
}
</code>
får jag felmeddelande:

1>------ Build started: Project: BattleTank2005, Configuration: Debug Win32 ------

1>BattleTank2005 - 1 error(s), 0 warning(s)
========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

Vad gör jag för fel?
Jag använder Visual C++ 2005.

ska det inte vara

void OnPaint(PaintEventArgs^e) override
{
...
}

Tack!
Jag fick felmeddelande då också,
men jag behövde bara lägga till virtual så löste det sig.
