Library question

Re: Library question

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!

Re: Library question

Adrian:

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

Re: Library question

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

Re: Library question

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.

I am getting these errors:

DrawListViewSub ItemEventArgs' could not be found
DrawListViewCol umnHeaderEventA rgs' could not be found

I am already referencing both:

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

Re: Library question

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!
