custom control

Hi all,

Can anyone please let me know the use of custom control in dialogue programming along with an example?

I want to crealt an input field in dialogue programming, but I want that the thickness of it should not be one line but it should be say 5 lines thick.

The comments box should be 5 lines thick - i dont want to keep 5 separate i/o fields there. Is it possible? Please suggest.

Thanks
