Color ComboBox

[NickThissen]

I get the Invalid Parameter exception too, on XP Media Center Edition 2005.

The Invalid Parameter exception occurs when you dispose a brush that is set to any of the default brushes in the Brushes enumeration, exactly what you are doing.
I'm not sure why that fails, but I suppose you can't Dispose a brush you are not specifically creating a new instance of..?

I don't understand why it fails every single time here, but works fine with you? Maybe a recent update 'fixed' / 'destroyed' (I'm not sure which of the two ) this, seeing as this thread is half a year old?

The fix is just to not dispose your brush.



By the way, great control, looks very similar to the Visual Studio one.
In my opinion, a Designer class with Smart Tags would work wonders on this control... You could set the color more easily during design-time that way, as well as quickly including or excluding system colors / transparent with a checkbox.

If you want to implement the Smart Tags, do a search for them in the codebank, I made a 'tutorial' about them a while ago.

EDIT
Actually, I was smart(-Tag) enough to include a dash in my topic title, so searching for 'Smart Tags' does not bring it up
