[RESOLVED] [02/03] RichTextBox opacity

[RS_Arm]

Hello!

I've done a little Notepad clone.

It works great. Now, what I want to do is to set different opacity to my text area (is a richtextbox object).

I want it to be just like this picture, setting the background area but not any of the text typed.

Thank you.

I've been trying to use the transparencyKey but all RTbox acts like it does not exist.
Do I have to use API?

It is really important to me to know if there is any chance to do what I would like to do.
If it is not possible, please tell me.

Thank you.

It may be possible in .NET 3.0+ but certainly not before without some extreme jiggery-pokery. It's simply not supported. Controls can't have individual opacity. Only the form has an Opacity property and it's for the entire form, child controls and all.

But do you think it can be done using API?
Thank you.

I very much doubt it, other than maybe on Vista.
