How can I shrink the client region of a textbox control?

[Uzi]

I wanna build a textbox, which derives the Forms.TextBox class, and add a button at the right end of that textbox. I call this TextEllipsis. But I haven't found out how to shrink the client region, so that the text doesn't hide under the button (which I draw).

In my opinion, you don't need to make you class
derive from TextBox.
you can make it inherit from another container class, like Panel, then add a TextBox object and a Button object on it.
But I am not sure...

But if I used your method, I will have to map many textbox's properties back and forth.
