Hi all,

I have a problem in Importing Namespace.
To be clear, I have two .vb files and I want to use
some functions which exist within the first .vb file in the second one.

Example:
In the first "x.vb" file I have functions X and Y.
I have a NameSpace called YYYYY in x.vb. i.e,

Imports System
.....
NameSpace YYYYY
public class MMM
.......
 function X()
 ......
 function Y()
.......

If I want to use functions X() and Y() from the above x.vb file
in my second file called z.vb, so how can I import functions X() and Y().

I tried to compile my second vb file by using " Import YYYYY", but I got YYYYY is not defined error.
Could you guys give me hint?
Thanks

The answer is right in front of you.

Imports System

Imports YYYYY

Hi,
I have tried to import YYYYY, and YYYYY.MMM
It does not work

Import[u]s</u> YYYYY

Just like

Import[u]s</u> System

Hi again,
I have tried many times, checked spelling and I only get
BC30466: Namespace or type 'YYYYY' not defined.
I am not good in .NET. Do u think that it has something to do
with web.config file.

Ok, let's back up a minute.
Can you describe your development scenario?
What are you developing in?
Are you compiling this code?
If you are developing in visual studio, are the two .vb files in the same project?

Hi again,

I tried to import it from .asmx file, it worked without complaining.
I think it is ok now, I tried to write a code that authenticate
users of a small web service through SOAP header. It seems it is working now.
I have a few question that I would like to ask you.
Do you know any good articles/books in .NET web service security, with examples?
Is there any password mask technology in VB?
You can look at the code written below (it is an .asmx file - web service), when I run it and enter the value for password parameter the whole text of password appears, how Could I make the password hidden in this case? I do not want to use soap header here.
