[dba-SQLServer] SQL Server 2000 - User Defined Functions - Calling From Visual Basic 6.0

To all,

I have just created my very first UDF in SQL Server 2000 basically I
want to use it to return a print address to a string variable in Visual
Basic 6.0, my function is as below:

CREATE FUNCTION [gng_create_PrintAddress] 
	(
		@strLine1 	[nvarchar](255),
		@strLine2	[nvarchar](255),
		@strLine3	[nvarchar](255),
		@strLine4	[nvarchar](255),
		@strLine5	[nvarchar](255),
		@strLine6	[nvarchar](255),
		@strPC		[nvarchar](255)
	
)  
RETURNS 
		[nvarchar](2000)
AS  
BEGIN 
	RETURN ISNULL(@strLine1+CHAR(13),'')	+
		   ISNULL(@strLine2+CHAR(13),'')	+
		   ISNULL(@strLine3+CHAR(13),'')	+
		   ISNULL(@strLine4+CHAR(13),'')	+
		   ISNULL(@strLine5+CHAR(13),'')	+
		   ISNULL(@strLine6+CHAR(13),'')	+
		   ISNULL(@strPC+CHAR(13),'')
END

In VB6 I have a data environment with a SQLConn connection, and if I
want to execute a stored procedure to return a recordset I do something
like the following:

Dim rsData As ADODB.Recordset
Set rsData = DEGNG.SQLConn.Execute("[SP Name]") and give it the
parameters if required.....

So I thought I could have something like below:

Dim strAdd As String
strAdd = DEGNG.SQLConn.Execute("gng_create_PrintAddress '" & Line1 & "',
'" & Line2 & "','" & Line3 & "', '" & Line4 & "', '" & Line5 & "', '" &
Line6 & "', '" & PCode & "'")

And then strAdd would contain the print address, but it give me an error
saying: Type Mismatch.
can anyone point me in the right direction here ?

Thanks in advance for any help on this, as I would really like to start
learning more about UDF's and using them instead of modules in VB6
