ToolTip tt = new ToolTip();

tt.SetToolTip(yourControl, "This is the tooltip");

You can also do this in the designer - see this article:

I think the OP wanted to be able to specify a tooltip for certain
sections of text in the RichTextBox. That would set a tooltip to the
whole control wouldn't it?

Not sure how you *would* go about setting tooltips just for certain bits
of text though.

Hi,

David, you're right, that is what Vinod is looking for.

Vinod...

This link will give you the idea... You will require the EM_CHARFROMPOS
message to get the character under the mouse's position. (InterOp
method)

Note : This is a VB 6.0 method, but hopefully you can adapt the syntax
to C#.

Wow, first time for everything I guess

I clearly misread the post. How embarassing, sorry!

Well, I spend more time in the .vb group, and a very common theme there
is that someone has found a C# sample to do X, and needs help
translating it into VB.NET. It's refreshing to see a VB6 sample offered
to a C#er But I suppose it makes sense, as the way VB6 people have
had to access the Win32 API for all these years is very close in
feeling to P/Invoke and Interop.

Hi Larry,

To tell you the truth, I spend most of my time in the VB group too. So
much so, that when I found and was posting the link to the sample, only
then I realized that this question was in the C# group. I thought, "Oh
well... he can convert it if he likes."

BTW, I'm not so fluent with the Win32 API and interop thing, so if you
know any good links where I could learn this...

Regards,

Cerebrus.

Hey Vinod,

Did you actually get this working?
