Whats the best way to write an observable collection to a txt file? I currently have the following public ObservableCollection<Account> SavedActionList = new ObservableCollection<Account>(); using (System.IO.StreamWriter file = new System.IO.StreamWriter("SavedAccounts.txt")) { foreach (Account item in SavedActionList) { file.WriteLine(item.ToString()); //doesn't work } file.Close(); } I'm not sure why it won't write to the file. Any ideas? You can easily just write: File.WriteAllLines("SavedAccounts.txt", SavedActionList.Select(item => item.ToString())); However, this will require your

I would love to be able to write to a local directory in my AsyncTask subclass, but I can't seem to figure out how to use getFilesDir(), since I cannot, to my knowledge, create an instance of ContextWrapper and Context in this subclass. So, what have I tried? I've tried getting the files directory the only way I know how by attempting many different things to create instances of Context and ContextWrapper in order to access the getFilesDir() method.

I have a variable with huge data some thing like this. $scope.employees = [ {"firstName":"John", "lastName":"Doe", "city": "Bangalore","State":karnataka,}, {"firstName":"Anna", "lastName":"Smith", "city": "Hyderabad","State":AndraPradesh,}, {"firstName":"Peter", "lastName": "Jones", "city": "Mumbai","State":Maharastra,}, ]; I want to save it to JSON file, when I click a button or something. $scope.employees is the object to be saved to a file $scope.savedJSON = angular.toJson($scope.employees,true); var blob = new Blob([$scope.savedJSON],{ type: "application/json;charset=utf-8;" }); var

I want to ping an IP address every 5 seconds. If the ping fails, write the date and time to a file. Here is my non-working attempt... the loop works as intended, but I can't get it to write to a file if the ping fails. @ECHO OFF set IPADDRESS=172.30.1.36 set INTERVAL=5 :PINGINTERVAL ping %IPADDRESS% -n 1 if errorlevel 1 echo %date% %time% >> failurelog.txt timeout %INTERVAL% GOTO PINGINTERVAL In ipv4, ping command only raises errorlevel if there are packets lost. But in you are pinging a machine in your same subnet, you get no packets lost. The easier way to test for ping success is to test
