Michael -

Very nice straightforward approach to this problem! I have previously created webservices to do this very thing (and Flex 4 has some nice new data connection features which facilitate this) but there’s one issue I can’t seem to get good information on that I was hoping you might be able to help me with.

Rather than binding the results to a datagrid I want to step through the results for post processing in the webservice result event. I recently uncovered a bit of code that casts the results into XML nodes and parses them that way and I’m intending on trying that out with your code since I think that the XML you’re returning is cleaner than the WSDL XML I have been returning previously, but I’m just curious to see if you didn’t have another approach you would take?

Any code snippets or links you could point me to would be great appreciated. Thanks again!

- Bob

where shall I use this method? Shall I create a new web form or do it in service.asmx.cs file which is being created by default.

[WebMethod]
02 public XmlDocument getDataXML(string strQuery, string strRootNode, string strItemNode)
03 {
04 // Create vars out of connection string and query string
05 string dbConn = dbConnString;
06 string dbQuery = strQuery;
07
08 // Connect to the database and run the query
09 SqlConnection conn = new SqlConnection(dbConn);
10 SqlCommand cmd = new SqlCommand(dbQuery, conn);
11 SqlDataAdapter da = new SqlDataAdapter();
12 DataSet ds = new DataSet();
13 ds.DataSetName = strRootNode;
14 da.SelectCommand = cmd;
15 da.Fill(ds, strItemNode);
16
17 // Return the data as XML
18 XmlDocument xmlDoc = new XmlDocument();
19 xmlDoc.LoadXml(ds.GetXml());
20 return xmlDoc;
21 }

hiii,
I have already developed flex application. till now i dint need any database connectivity. but now i need it. For connection in Flex,while starting to make the project you need to specify what technology will u use for database connectivity. But i dint specify anything at that time. So how can i do it now?
How can i specify now that my project will use .net for connectivity.

thanx.

Hi Michael

Just trying to work through your example – using Visual Studio 2008

I am getting the following error:
Error 1 The type or namespace name ‘XmlDocument’ could not be found (are you missing a using directive or an assembly reference?)

Yea I was able to get it working, but I wrote it =).

So testing the WSDL returns data?

What’s the problem you are having in Flex does it return an error or just no data?

same problem as Carl. wsdl seems to be working fine, but flex does not return any result after making a web service call. Could anyone get this working ?
