[Mono-list] asp.net and Npgsql namespace not found

[Carl Olsen]

Hi Alan,

I've never tried to compile it on the fly.  I always pre-compile everything.
Use "protected" instead of "private" when you do a button click in a code
behind page, unless you use an event handler.  I'm not an expert, but it
appears that I can use a private method when I have an event handler, and it
appears that I need to use protected methods when I simple call the function
from the aspx page.  I'm reading books on OOP, but I'm still just a
beginner.  It sounds like you could benefit from a book on OOP.  I'm reading
OOP for C# and OOP for PHP, and it helps to see it used with a couple
different programming languages, so you really see how it sits under the
language as the foundation.  Apress and Wrox have excellent books on these
topics, although I think that the Apress books have the edge.

Carl

Carl,

do you compile your codebehind pages into dlls?  If I compile my
codebehind into a dll the error disappears.  Do you think that if the
codebehind page is compiled on the fly it doesn't find the Npgsql
library?

Using the compiled codebehind dll I not get errors like
test.Button1_Click(object, System.EventArgs)' is inaccessible due to
its protection level

Looks like I will have to search for a solution to this problem.

thanks,
Alan.
