Cheap Windows 7 Home Basic Writing A Quick Applica

With the release of the Windows Live ID SDK comes the ability to add the trusted security of Windows Live to your application,buy windows 7 Home Basic, but how much work is needed to actually get this functionality into your program? Turns out,Office Standard 2010 Product Key, not a lot. In fact, for just getting a working sign in window and a message to show that the user is authenticated, it only requires about 5 lines of code that you need to write. Here I will show you how to add basic functionality to your program to give you a quickstart with using the SDK.
I’ll assume at this point that you have already downloaded and installed the SDK. So we first of all need to add the reference to our project to let Visual Studio know what to use, the reference we need to add is Microsoft.WindowsLive.Id.Client:

We will also need to put the using code in:
using Microsoft.WindowsLive.Id.Client;
Now,Office Professional 2010 Product Key, I mentioned that you only really need just 5 lines of code for this so I’ll quickly show you those lines of code and then expand upon that and show a small sample program. Now, first off create yourself a Windows Form in Visual Studio, something like the following:

The code for when button1 is pressed is simply as follows:
private void button1_Click(object sender, EventArgs e) { IdentityManager idmgr = IdentityManager.CreateInstance("My App ID", "My Own Sample Program"); Identity id = idmgr.CreateIdentity(); id.Authenticate(); if (id.IsAuthenticated) MessageBox.Show("User authenticated"); }
And that’s it, that will bring up the familiar Windows Live sign in window, once signed in, it will pop up with a message saying you’re logged in. That is the real basics of using the Windows Live ID SDK. Now I’ll show you a quick example that will allow the user to sign out, too, and also have part of the form be changed by the fact that you’ve signed in.
Create yourself a Windows Form, and put in a button (btnSignIn) and a label (lblInfo), mine looks like this:

We start off with declaring the two main objects which are the IdentityManager and Identity Objects:
namespace LiveIDApp
{ public partial class frmMain : Form { IdentityManager idmgr; Identity oID; public frmMain() { InitializeComponent(); idmgr = IdentityManager.CreateInstance("ScottIsAFool;wlm@s cottisafool.co.uk;Scøtt's Test App",Cheap Windows 7 Home Basic, "Scøtt's Windows Live ID Test App"); oID = idmgr.CreateIdentity(); }
Now, you’ll notice that when we use the CreateInstance method we have a string that is the AppID. This should typically be made up of CompanyName;EmailAddress;ApplicationName, followed by the ApplicationName string in its own field, this is what will be shown in the Live ID window when the user signs in.
This time when the button is clicked, we’re going to do just a little bit more than in the quick example above:
private void btnSignIn_Click(object sender, EventArgs e) { // Check if a user is already signed in if (!oID.IsAuthenticated) { // Opens the Sign in window. On successful sign in, oID.Authenticate() // will return true. if (oID.Authenticate()) { // Change the label text to show we're signed in and as whom lblInfo.Text = "Signed in as: " + oID.UserName; btnSignIn.Text = "&Sign Out"; } else { MessageBox.Show("Authentication failed"); } } // If a user is signed in, then we are assuming that they want to sign out else { // This closes the active connection to the server oID.CloseIdentityHandle(); // Resets the label and button text lblInfo.Text = "Not signed in"; btnSignIn.Text = "&Sign In"; } }
And that’s it, so now when we click on the button, we will get the Windows Live sign in window:

And then once we have successfully signed in, our application will now look like this:

So there we have a basic example of how to use the Windows Live ID SDK. There are more uses of this,Office Professional Plus 2010 Sale, and they can be seen in the SDK documentation, and if you really want to utilize this SDK, I would recommend looking through it and seeing what else can be done.
Note: With this example I have put in no error handling.
