DLL register problem

[Alan]

I created a DLL and tried to register with regasm.exe but got error:

RegAsm: warning RA0000 : No types were registered.


I check that I got the 'no args constructor', so it should be OK.
But it still gave me this warning.

This is the cutdown version of my class:

using System;

using System.Collections.Generic;

using System.Text;

using System.Data.SqlClient;

using System.Data;

namespace DocumentClassLibrary

{

public class DocumentClassLib

{

private string _ConnectionString;

private SqlConnection _Conn;


public DocumentClassLib()

{

_ConnectionString =
"Provider=SQLOLEDB.1;server=myhost;Trusted_Connection=yes;database=mydb;User
ID=alan;Password=alan";

_Conn = new SqlConnection(_ConnectionString);

}

..........

I can now register the DLL by going to project options, set the Visible to
COM check box.

But the problem now is got a runtime error when creating an object in a
webpage using VBScript.
I tried to create a simple DLL also got the same runtime error.

Did you create the tlb (tlbexp YouComponent.dll ) which is used by VB to call
your methods?

Ah yes, again now I can create the com object in VBScript.
But again, another problem is I have methods in this DLL which returns
object like DataSet, I got an error like
incorrect call of procedure or argument.

This also happens in methods that require parameters whose type are object,
array..
eg.

public void CalSum(string[] aIntArr)
public DataSet GetEmployeeBatch(int aEmployeeID)

I don't know if it caused by VBScript that does not know about .NET 2.0
class?
