Hi,
I have a question about file included in ASP.NET. I have a file that
includes all the Sub functions (e.g FileFunct.vb). One of the functions
in this file is :
Sub TestFunct(ByVal strInput As String)
return (strInput & " test")
End Sub
I'd like to call this function in FileFunct.vb from another .ASPX file
like this :
<%@ import Namespace="System" %>
<%@ import Namespace="System.Data" %>
<html>
<head>
<title>Test page</title>
</head>
<body>
<script runat="server" language="VB" scr="FileFunct.vb" >
Sub Page_Load(s As Object, e As EventArgs)
Dim result=TestFunct("This is a string")
response.write("<BR>result ==> " & result)
End Sub
</script>
</body>
</html>
I've got this error:
Server Error in '/' Application.

Make TestFunc shared and access it via
ClassName.TextFunc
so, it would look like
public class Utility
public shared TestFunct(..)
...
end function
end class
and you would use it like:
Utility.TestFunct(...)

You're not thinking fourth-dimensionally! (- Back to the Future)
Actually, you're not thinking Object-Orientationally.
ASP.Net is object-oriented, and you'd better get acquainted with it, or
you'll be visiting here almost daily, and writing crappy code until you do.
Let me elaborate, if you will:
Files are source code. Your application doesn't have files. It has classes.
A file defines a class, but IS not a class. A class is a data type, and
exists in the context of a running application. So, when you're talking
about how your application works, the first thing you need to do is think
about classes, not files. A file can contain one or MORE class definitions,
and you need to get acquainted with classes to be successful with .Net.
Classes are very important in .Net programming; Objects are made from
classes, and classes provide encapsulation. Object-oriented programming can
get pretty darned complex, and encapsulation can save you a lot of grief, by
hiding those things which need hiding from those things that don't need
them.
If you have a file with a bunch of Subs and Functions in it, you need to
create a class with Subs and Functions in it. These Subs and Functions can
be Shared (meaning that they are singleton objects that don't require a
class instance to operate), or they can be Instance (meaning that an
instance of the class containing them must be created in order to use them).
The advantage to Shared data and process is that it doesn't require a class
instance, and is, in essence "global," available to the entire application.
This is also the disadvantage of Shared data and process. Anything can get
to it, and change it, and in a multi-threaded app (unlike VB 6, .net is
multi-threaded), this can cause all sorts of problems. Unless you're
familiar with the issues, I would stick with classes that require
instantiation. Instantiation is the process of creating a copy (instance) of
a class that is limited in its scope (availability), and is thread-safe.
Once you create an instance of a class, you can access any Public or Friend
(Friend is more protected than Public, but you shouldn't run into issues
right away) members from any other class that references the instance.
From your question, and the code you posted, I can see that you require a
good bit more education and practice. I would recommend the .Net SDK, a free
download from: http://www.microsoft.com/downloads/d...displaylang=en
It is extremely important to know the difference between ASP and ASP.Net,
between VBScript or VB 6, and VB.Net. The first are procedural,
single-threaded, and easy to use for small applications. .Net is
object-oriented, multi-threaded, and easy to use once you spend a great deal
of time studying it, but incredibly hard to use if you don't.

Kevin,
Last time I put all the files in my application (project name) using Visual
Studio.NET, declared a class (AClass) which has some functions, and saved
them in a file (.vb file). My program worked fine when I called the function
from my other .vb files (AClass.Function1, ...). My application was
Object-Oriented well development. Now, I'd like to try another way :
creating .ASPX file that contains VB.NET script, HTML and call one function
from another .vb file without using Visual Studio.NET. Can I do that and How
? It's my question.

Hi Kevin,
This article is what you need when using asp.net 1.1 http://aspnet.4guysfromrolla.com/articles/122403-1.aspx
It gest even simpler if you use asp.net v2. In this cas just drop the class
file in the App_Code directory and you can call them everywhere.
Let me know if you have any more questions...

by hiding those things which need hiding from those things that don't need
them.
If you have a file with a bunch of Subs and Functions in it, you need to
create a class with Subs and Functions in it. These Subs and Functions
can
be Shared (meaning that they are singleton objects that don't require a
class instance to operate), or they can be Instance (meaning that an
instance of the class containing them must be created in order to use
them). The advantage to Shared data and process is that it doesn't require a
class instance, and is, in essence "global," available to the entire
application. This is also the disadvantage of Shared data and process. Anything can
get
to it, and change it, and in a multi-threaded app (unlike VB 6, .net is
multi-threaded), this can cause all sorts of problems. Unless you're
familiar with the issues, I would stick with classes that require
instantiation. Instantiation is the process of creating a copy (instance)
of a class that is limited in its scope (availability), and is thread-safe.
Once you create an instance of a class, you can access any Public or
Friend (Friend is more protected than Public, but you shouldn't run into issues
right away) members from any other class that references the instance.
From your question, and the code you posted, I can see that you require a
good bit more education and practice. I would recommend the .Net SDK, a
free download from:
http://www.microsoft.com/downloads/d...displaylang=en
It is extremely important to know the difference between ASP and ASP.Net,
between VBScript or VB 6, and VB.Net. The first are procedural,
single-threaded, and easy to use for small applications. .Net is
object-oriented, multi-threaded, and easy to use once you spend a great
deal of time studying it, but incredibly hard to use if you don't.

Thanks, Tom. I did try it last time and it worked when I put all the files
in an application using Visual Studio.NET. My requirement now is to create
a single .ASPX file containing VB.NET language, JavaScript language and
HTML, and call a function from this .ASPX file without using Visual
Studio.NET to create an application.

This article is what you need when using asp.net 1.1
http://aspnet.4guysfromrolla.com/articles/122403-1.aspx
It gest even simpler if you use asp.net v2. In this cas just drop the
class file in the App_Code directory and you can call them everywhere.

You're not thinking fourth-dimensionally! (- Back to the Future)
Actually, you're not thinking Object-Orientationally.
ASP.Net is object-oriented, and you'd better get acquainted with it,
or you'll be visiting here almost daily, and writing crappy code until
you do. Let me elaborate, if you will:
Files are source code. Your application doesn't have files. It has
classes. A file defines a class, but IS not a class. A class is a data
type, and exists in the context of a running application. So, when
you're talking about how your application works, the first thing you
need to do is think about classes, not files. A file can contain one
or MORE class definitions, and you need to get acquainted with classes
to be successful with .Net.
Classes are very important in .Net programming; Objects are made from
classes, and classes provide encapsulation. Object-oriented
programming can get pretty darned complex, and encapsulation can save
you a lot of grief, by hiding those things which need hiding from
those things that don't need them.
If you have a file with a bunch of Subs and Functions in it, you need
to create a class with Subs and Functions in it. These Subs and
Functions can be Shared (meaning that they are singleton objects that
don't require a class instance to operate), or they can be Instance
(meaning that an instance of the class containing them must be created
in order to use them). The advantage to Shared data and process is
that it doesn't require a class instance, and is, in essence "global,"
available to the entire application. This is also the disadvantage of

Hi,
I have a question about file included in ASP.NET. I have a file
that includes all the Sub functions (e.g FileFunct.vb). One of the
functions in this file is :
Sub TestFunct(ByVal strInput As String)
return (strInput & " test")
End Sub
I'd like to call this function in FileFunct.vb from another .ASPX
file like this :
<%@ import Namespace="System" %>
<%@ import Namespace="System.Data" %>

<head>
<title>Test page</title>

Dim result=TestFunct("This is a string")
response.write("<BR>result ==> " & result)
End Sub
</script>

Thanks in advance.
If you use asp.net version 1 you need to compile the class file with the
command line compiler and put the created dll in the bin directory.
Check out this 2 part article : http://www.4guysfromrolla.com/webtech/112101-1.2.shtml
If you use asp.net version 2 just drop the class files in the App_Code and
that's it. The engine will compile all files in this dir and make it available
to the whole app without us to worry about compilation
Let me know if it helped you or not...
