Compiling Problems

[Roberto Modica]

Hi all,

I am trying to create a namespace hierachy but i think i
am doing something wrong.

I have an DAL vb file with the namespace:

CompanyName.newsletter.DAL

and i compile that using the standard vbc in command
prompt routine, and that works. then i try and create a
Business Layer vb file, with the namespace:

CompanyName.Newsletter.BLL

But for this to work i have to compile both files
together, even though i have imported the
CompanyName.newsletter.DAL namespace. What am i doing
wrong, as i want the two files to sit in two seperate
assemblies.

Please Help!

Rob

Are you *referencing* the assembly containing
CompanyName.newsletter.DAL when you compile the second one? Importing a
namespace isn't the same thing as referencing an assembly.

In the "References" part of the project, click on Add Reference. Go to
the Projects tab, and select the project you want to add a reference
to.

Hi Again John,

i am not using Visual Studio.Net so how would i add referencing without
it??

Sorry - I misread your previous post!

Use the /r command line parameter to add a reference, e.g.

vbc /r:Foo.dll ... (the other arguments)

I have tried that before,

i have created a assembly called:

Newsletter.DAL.dll and placed it into my Bin directory(application
wide), i have even placed it in a bin directory which sits in the same
directory as my business component:

so i add the /r:newsletter.data.dll line to my vbc and it returns an
error:

Command Line Error BC2017: Could Not Find Library 'newsletter.Data.dll"

my command line is:

vbc /t:library /out:newsletter.dll *.vb /r:system.dll /r:system.data.dll
/r:system.xml.dll /r:system.web.dll /r:newsletter.data.dll

am i doing something wrong.

Yes - if you've placed it in your bin directory, you need to use

/r:bin\newsletter.data.dll

I suspect you don't need to add the other references though - they're
probably added automatically. (They are in C#, at least.)
