' Write to an existing file: MyApp1\SubDir1\MyApp1A.txt ' Determine if the file exists before writing to it. Dim filePath As String = Path.Combine(subdirectory1, "MyApp1A.txt") If store.FileExists(filePath) Then Try Using sw As StreamWriter = _ New StreamWriter(store.OpenFile(filePath, FileMode.Open, FileAccess.Write)) sw.WriteLine("To do list:") sw.WriteLine("1. Buy supplies.") End Using Catch ex As IsolatedStorageException sb.AppendLine(ex.Message) End Try Else sb.AppendLine((filePath + "does not exist")) End If
