asp.net building controls: Hi,

i tried to create my own custom controls and met following problems:
-according to the book "Programming ASP.NET" i created two projects
within my solution. one is the main and the other holds the custom
controls. as output path i set the binary directory of the inetpub path.
all works fine except that the custom controls also needs access to the
classes within the main project. after compiling i get the error
message, that the binary file could not have been copied, because it was
in use by another process. what should i do in this case?
-is there a way, that the custom control hast direct access to the
request object of a page where it is used?
-when i add a custom control via the command "controls.add(oControl)" to
a web page it disappears after a postback. what must i do to make it
"constant"?

greetings,

Hi Rainer,

Yes, you can use System.Web.HttpContext.Current.Request

You need to add the control everytime, no matter the value of IsPostBack or
anything else. If you only add the control when a specific condition is met
(ie. IsPostBack == false or a click button, etc) then next time the page is
posted back your control won't be there. This is because ASP.NET doesn't
"automagically remember" previously created dynamic controls.
