c# - navigate after code on button click -


I'm wondering is performed on a bit and after some code a button of a shell that I another Click Navigate to the page? Here's what I have 

  private void saveButton_Click (object sender, RoutedEventArgs e) {try {address = bitCoinAddress.Text; Create a MyIsolatedStorage.CreateDirectory ("Contact") called the // location directory; // (, FileMode.Create, myIsolatedStorage) New IsolatedStorageFileStream ( "Contact \\ me.txt") locationData create directories WriteFile = new StreamWriter called location.txt within the file; WriteFile.WriteLine (address); WriteFile.Close (); Navigation service Navigate (new Uri ("/ Contacts.xaml", Uricund.Relative)); } Hold (exception b) {message box. Show ("Error saving bittoon address"); Console.light line ("an error occurred:" + b); }   
 
 
 Most certainly, the problem is in this line:  < Pre>  myIsolatedStorage.CreateDirectory ("Contact");

Because you can not guarantee button_click event that myIsolatedStorage object is still alive (it may already be settled, the code should be wrapped using the < / Em> to stop that). In this style you rewrite the code: 

  using (myIsolatedStorage = IsolatedStorageFile.GetUserStoreForApplication ()) {if (! MyIsolatedStorage.DirectoryExists ( "Contact")) myIsolatedStorage.CreateDirectory ( "Contact") ; Using (WriteFile = new StreamWriter (new IsolatedStorageFileStream ( "Contact \\ me.txt", FileMode.Create, myIsolatedStorage))) {writeFile.WriteLine (address); }} Navigation service Navigate (new Uri ("/ Contacts.xaml", Uricund.Relative));

This code works fine for me Hope it helps.

ios - How do I use CFArrayRef in Swift? -

I am using Objective-class in my Swift Project through a bridging header. The method signature looks like this: - Some cement (some type) some parameters; I started by getting an example of class, calling method, and storing the value: var myInstance = MyClassWithThatMethod (); Var cfArr = myInstance.someMethod (some value); Then try to get the value in the array: var valueInArrayThatIWant = CFArrayGetValueAtIndex (cfArr, 0); However, I get the error unmanaged & lt; Cfarray & gt; Not like 'CFArray' . Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
