Make dll that contain one function. Help Please.

Vb.Net Make dll that contain one function. Help Please.
I would like to call a function from different applications.
I think i have to make a dll.
I have Visual Basic.net 2003 Standard Edition, that teorically does
not make dll,
but pratically does.

I search vbc.exe and copy it to a new folder, in which i have the
following batch file

Make a New folder.
Search "vbc.exe" and Copy it to the new folder.
Make a new Batch file, whith the following code and name it

"vbc.exe" /target:library /out:My_dll
/reference:System.dll,System.Data.dll,System.Drawin g.dll,System.Windows.Forms.dll,System.XML.dll

Of course "My_Code.vb" contains the dll code.
I would like to put there a function i can call from any application.

Just as example there is a simple function by: Tom Harris at the
following address
that removes unwanted chars.
using that function as example how would the code be in "My_Code.vb" ?
Can somebody help ?

Best Regards.

The OOP way to do it would be to make the function a shared function
on some class and import the class's namespace in the calling code
(where the calls will be ClassName.FunctionName).

The VB6 way to do it would be to put the function inside a module and
then import the module in the calling code (calls will be just
