I am using this code to convery an (.ODT) document into MS Word 2007 format.

Code:
private void Browse_Click(object sender, EventArgs e) 
        { 
            // Displays an OpenFileDialog so the user can select a Cursor. 
            OpenFileDialog openFileDialog1 = new OpenFileDialog(); 
            openFileDialog1.Filter = "Open Office Document|*.odt"; 
            openFileDialog1.Title = "Select an Open Office Document"; 

            // Show the Dialog. 
            // If the user clicked OK in the dialog and 
            // a .CUR file was selected, open it. 
            if (openFileDialog1.ShowDialog() == DialogResult.OK) 
            { 
                file = txtODTFile.Text = openFileDialog1.FileName; 
            } 
        }  private void Convert_Click(object sender, EventArgs e) 
        { 
            unoidl.com.sun.star.uno.XComponentContext xLocalContext = uno.util.Bootstrap.bootstrap(); 
            unoidl.com.sun.star.lang.XMultiServiceFactory xRemoteFactory = 
                                        (unoidl.com.sun.star.lang.XMultiServiceFactory)xLocalContext.getServiceManager(); 

            XComponentLoader aLoader = (XComponentLoader)xRemoteFactory.createInstance("com.sun.star.frame.Desktop"); 
            XComponent xComponent = initDocument(aLoader, PathConverter(file), "_blank"); 
            saveDocument(xComponent, file, PathConverter(file)); 
        }
and

Code:
 private static XComponent initDocument(XComponentLoader aLoader, string file, string target) 
        { 
            try 
            { 
                PropertyValue[] openProps = new PropertyValue[1]; 
                openProps[0] = new PropertyValue(); 
                openProps[0].Name = "Hidden"; 
                openProps[0].Value = new uno.Any(true); 

                XComponent xComponent = aLoader.loadComponentFromURL(file, target, 0, openProps); 
                return xComponent; 
            } 
            catch (System.Exception Exp) 
            { 
                MessageBox.Show(Exp.Message); 
                return null; 
            } 
            finally 
            { 
                aLoader = null; 
                file = null; 
                target = null; 
            } 
        } 

        private static void saveDocument(XComponent xComponent, string sourceFile, string destinationFile) 
        { 
            PropertyValue[] propertyValues = new PropertyValue[1]; 
            propertyValues[0] = new PropertyValue(); 
            propertyValues[0].Name = "Overwrite"; 
            propertyValues[0].Value = new uno.Any("MS Word 2007"); 
            ((XStorable)xComponent).storeToURL(destinationFile, propertyValues); 
        } 

        private static string PathConverter(string file) 
        { 
            if (file == null || file.Length == 0) 
                throw new NullReferenceException("Null or empty file passed to the office"); 
            file = file.Replace(".odt",".doc"); 
            return String.Format("file:///{0}", file.Replace(@"\", "/")); 
        }
But while debugging at this point.....

((XStorable)xComponent).storeToURL(destinationFile, propertyValues);

It is throwing exception stating that "An unhandled exception of type 'unoidl.com.sun.star.task.ErrorCodeIOException' occurred in mscorlib.dll". How can i over come this problem??

Thanks in Advance
