Library question

[> Adrian <]

I am getting these errors:

DrawListViewItemEventArgs' could not be found
DrawListViewSubItemEventArgs' could not be found
DrawListViewColumnHeaderEventArgs' could not be found

I am already referencing both:
System.Drawing
System.Drawing.Design

Which else should I reference to get rid of these errors?

Adrian.

Hello Adrian,

all the three classes are defined in System.Windows.Forms namespace, so add
"using System.Windows.Forms;" to your C# code.

That should do it!

Adrian:

Maybe a silly question, but are you including a "using" directive?

Not a silly question at all,
however "using" is there.

Hello,

can you post your code that shows the error and the complete error message?

There must be something else going on in your code if you have the
references/using statements already in place.

Are you sure you are using Framework v2.0?

I have got it to run. It would not run on VS2003, but it will run on V2005.
I did make some changes though. However the header back color is read only,
so I am stuck, because specifically that I wanted to change.

So you were not running V2 of the framework after all, VS2003 targets V1.x!
