Samrtphone app data storage

I am working on a very simple Smartphone app. I want to store 3 little application settings. I can't figure this mess out. I have beat my head against the wall trying the sample at the following link http://msdn.microsoft.com/en-us/library/ms839369.aspx

IT DOESN'T WORK!

I keep coming up with a NULLReferenceError on the following that is BOLD (xmlApplicationData) : (this is straight from the sample)

Code:

---

public class ApplicationData
        {
                private const string xsdApplicationData = @"\Storage\Program Files\ISBNAnyplace\ApplicationData.xsd";
                private const string xmlApplicationData = @"\Storage\Program Files\ISBNAnyplace\ISDNAnyplace.xml";

                public DataSet GetAll()
                {
                        // Iniate new dataset
                        DataSet ds = new DataSet();
                       
                        // Read schema and xml
                        ds.ReadXmlSchema(xsdApplicationData);
                       
                        // Return the dataset regardless if ReadXml throws an exception or not
                        // There is no dataset the first time the application runs
                        try
                        {
                                ds.ReadXml(xmlApplicationData);
                        }
                        catch {}

                        // Return dataset
                        return ds;
                }

if anyone knows a better way please let me know where i can find some samples. This is the last piece ... well except for deployment. Come on how hard could that be!:bigyello:

Hey,

Have you tried stepping through your code in the debugger? What you have described would indicate that the XML File isn't there. Which would sort of make sense as I do not think you have constructed the path correctly.

P.S. I have asked for your thread to be moved to the Mobile Development Forum
