Why when I get MacAdress there is different Values when NetworkAdapter is Enabled and Disabled...? Please help, i need to take unique ID..
var networkInterface : Object = NetworkInfo.networkInfo.findInterfaces();
var networkInfo : Object = networkInterface[0];
var strNet : String = networkInfo.hardwareAddress.toString();
trace(strNet);
Maybe flash get mac address of default network interface from the OS. When you turn off one interface, OS get another as default. As mentioned by Apocalyptic0n3, using UID is a better way. And you can save UID in Flash Shared Object for next running...

I'm making a simple helper class for accessing my barcode scanner. I can do it using SerialPort constructor like:
new SerialPort("COM4", 9600, Parity.None, 8, StopBits.One);
But I want my class to autodetect propper port name, so I first find the DeviceInformation:
var all = await DeviceInformation.FindAllAsync();
var foundBarcode = all.First(device => device.Name.ToLower().Contains("barcode"));
Then I try to get It like this:
var serialDevice = await SerialDevice.FromIdAsync(foundBarcode.Id);
But when I do so I get 'System.IO.DirectoryNotFoundException' in System.Private.CoreLib.dll.
How can I fix it?
PS.
I have serial communication capability in my manifest.
I found a solution, appearently
DeviceInformation.FindAllAsync();
returns items with different ids than
string selector = SerialDevice.GetDeviceSelector();
var all = await DeviceInformation.FindAllAsync(selector);
Now it works, I guess when first approach adds some USB identificator for emulated COMs.
I'm trying to change page and send some data to the new page just create. Basicaly, I have a page where the user could log, I'm gonna save the informations and then I'm going to open a new page by sendind the information to my "profil" page, where the user will have the information about his account. I'm using the MVVM patern, I don't know if it's going to change something but I ad this precision ;).
Edit: The only solution i have found is to pass the string of my object (gladly it is just strings). Because we can pass strings to another page. But I would prefer to give my object directly, or change my architecture if needed. Like don't create a page but replace my Usercontroles by others :(.
Thanks for the help.
For temp data:
If it is WP silverlight app, we can directly assign object to public property of destination page in OnNavigateFrom event of source page. For example, we can declare a public property A on Dest page, and implement the following in Source page to pass the user object:
protected override void OnNavigatedFrom(NavigationEventArgs e)
{
Dest destPage = e.Content as Dest;
if(destPage != null)
{
User a = new User();
a.UserName = "aa";
a.ID = 1;
destPage.A = a;
}
}
For WP runtime app on WP 8.1, you can directly use Frame.Navigate(TypeName, Object) to pass the parameter.
For persist data:
I will suggest storing the data to local storage on source page and read it from destination page.
If I understand right you should use parameters in navigate URI
For example to send name you can use:
NavigationService.Navigate(new Uri("/View/Page.xaml?name=UserName", UriKind.Relative));
and then in OnNavigatedTo() check name parameter:
string name;
NavigationContext.QueryString.TryGetValue("name", out name);
You can use IsolatedStorageSettings.ApplicationSettings["keyname"]=yourobject;
And whenever you want to use this value just unbox this value as below,
if(IsolatedStorageSettings.ApplicationSettings.Contains("keyname"))
{
var obj=(yourobject)IsolatedStorageSettings.ApplicationSettings["keyname"];
}
i need to select a video file and convert it to a byte array. the file i am trying to select has been recorded by the cameraUi interface. i can get the path to the file using
fileName = media.file.url;
readFileIntoByteArray(filePath, inBytes);
when i am passing it into the byte array i need to select directory first and then pass in the the rest of the path.
private function readFileIntoByteArray(fileName:String, data:ByteArray):void
{
var inFile:File = File.userDirectory;
inFile = inFile.resolvePath(fileName);
trace (inFile.url);
inStream.open(inFile , FileMode.READ);
inStream.readBytes(data);
}
this leads to duplication of the first part of the path.
i want to keep this dynamic as it will be run on different devices. i hard coded the file into the the variables section of flash debugger and it worked also i get an error if i leave out file.userDirectory
thanks in advance any help would be appreciated
You should always use File.applicationStorageDirectory instead of File.userDirectory. Due to security risk will vary to vary different device. File.applicationStorageDirectory will work any device.
Robust way of working with filepath
var firstPartPath:String = File.applicationStorageDirectory.nativePath;
var fullPath:String = File.applicationStorageDirectory.resolvePath("fileName.jpg").nativePath;
var expectedPath:String = fullPath.replace(firstPartPath,""); // "/fileName.jpg"
Here expectedPath value you should pass around your project instead of hard code value like c:\users\XXXX\ and save into database also use expectedPath value.
For latter access file just pass only expectedPath.
var inFile:File = File.applicationStorageDirectory.resolvePath(expectedPath);
Needn't worry about forward and backword slashes. File resolvePath() take care for you.
private function readFileIntoByteArray(fileName:String, data:ByteArray):void
{
var inFile:File = File.applicationStorageDirectory.resolvePath(fileName);
trace (inFile.url);
trace (inFile.nativePath);
trace (inFile.exists); //if file present true else false.
inStream.open(inFile , FileMode.READ);
inStream.readBytes(data);
}
I am looking for a way to uniquely identify a user in WinRT and preferably in WP8 as well. In WP7 applications, I could get a hash of the Live ID to do this, but I am not sure of how to approach this in WinRT environment. One of the goals here is to identify the user in Windows 8 environment as a whole. Using LiveID in one form or another would be ok in this case. I found some sources but they also mentioned that this might require some Enterprise Security permissions (or such) that are not welcome in the Windows Marketplace.
Say I want to identify the user based on the live id, I want to do it automatically and across multiple devices (PC, Tablet, maybe WP8). What resources should I be looking for?
You can obtain ID of each live user if you are using Live SDK. Here's code for you.
private async Task<string> GetLiveUserId()
{
string ID = "";
var auth = new LiveAuthClient();
var loginResult = await auth.LoginAsync(new string[] { "wl.signin", "wl.basic" });
if (loginResult.Status == LiveConnectSessionStatus.Connected)
{
var liveClient = new LiveConnectClient(loginResult.Session);
var myData = await liveClient.GetAsync("me");
ID = myData.Result["id"].ToString();
}
return ID;
}
I want a user to press an excel button and get prompted to download an excel file. I normally do it like this:
var dest:String = excelEndpoint;
var request:URLRequest = new URLRequest();
request.url = dest;
fr.download( request,'Locates.xls' );
fr.addEventListener(HTTPStatusEvent.HTTP_STATUS, handleStatus);
fr.addEventListener(IOErrorEvent.IO_ERROR, handleErr);
However, now I need to pass an object to the servlet. Seeing that you can't do that with URLRequest I tried using HTTPService:
var service:HTTPService = new HTTPService();
service.url = excelEndpoint;
service.method = "POST";
service.showBusyCursor = true;
service.addEventListener("result", httpResult);
service.addEventListener("fault", httpFault);
service.send( myObject);
Now I can get my data (myObject) to the servlet successfully, but I don't get prompted for a download.
How can I do that? Is it even possible with HTTPService?
Thanks for any helpful tips.
I don't think there is anything you can do w/ a remote request from the Flash Player to prompt the user to download something. The way I have done this in the past is two fold:
Remote request pings server that generates the excel file and saves it to a temporary directory. The request returns a URL to the Flex app as the result of the call.
When Flex app gets the result--a URL--it creates a URL request and pops it open in a new window, prompting the user to download the generated excel sheet.
I don't see a way to do this in one shot; because the return value from the Flex HTTPService call goes to the Flash Player, not the browser.
SOLVED:
I wanted to accomplish this with 1 remote call and the way I found to do this while passing an object that contained collections is this:
var uv:URLVariables = new URLVariables();
uv.typesColl = myObj.types.toString();
uv.partiesColl = myObj.parties.toString();
uv.statuses = myObj.statuses.toString();
Basically, create a property on the URLVariables object for each collection and then set all collections toString();
Hope that helps someone.
