Hi
I want urgent help with VB6 code.

Heres the scenario:
I have an application. From application API I can define an interface to my VB DLL (for example: myDLL.myClass.myfunction)
From my application, I can select table and its columns to be used by myDLL
The data is exchanged in XML format.

I want to read this XML file/data into my function - Public Function myFunction(sXML As String) As Variant
This function,
-  reads XML file for tablename, column ID and corresponding column data - i.e
-  connect to SQL Server7.0
-  deletes the existing data in table in SQL Server using column ID info from XML
-  then updates same table with new data read from XML file

I have installed MSXML4.0
I need your help to create DLL, register and compile it

I am willing to start a new thread as and when required so that expert who is helping me gets as many point as possible!

is this homework .. or have u tried writing some code and is stuck at some place?

read MSDN on how to load an XML file into XMLDOM and how to query using xpath ...

something like
Public Function myFunction(sXML As String) As Variant
Dim xmlDoc
set xmlDoc = Server.CreateObject("Microsoft.XMLDOM")
xmlDoc.async = false
xmlDoc.loadxml(sXML)
...loop through the nodes and construct the SQL string ...

y i asked that was because normally someone would post a question here only when they have already tried something and require help when they get some error which he/she is not able to solve. In ur case, u have asked for the complete code .. i do not think any expert might have the time to write the complete code for you .. anyway u might be lucky and get someone to do it ... all the best ...

sorry i posted the wrong solution ... try this ...

just add the refrence to "Microsoft xml" in ur project

 Dim xmlDoc As New MSXML2.DOMDocument40
xmlDoc.async = false
xmlDoc.loadxml(sXML)
set lobjRootNode = lobjXMLDoc.documentElement


loop through the "lobjRootNode" object to create the SQL string ...
