This topic explains the prerequisites, the process of including and using Tally Authentication Library in the Windows 8.1 application project, and the available API/methods.
1. Add the required images in images folder. If it is a universal application, create the images folder in the shared part.
2. Enable support for toast notifications from the manifest file, Package.appxmanifest. Toast notifications provide messages during the authentication process to users in an unobtrusive manner. In universal applications, this is done individually for both Windows 8.1 and Windows Phone 8.1 application.
Configuration of Package.appxmanifest file is shown below:
Add the library as a reference to your project using Add Reference option, by right-clicking the project. In universal applications, this is done individually for both Windows 8.1 and Windows Phone 8.1 application.
Adding library using Add Reference option is shown below:
1. To include the library
using TallyAuthenticationLibrary;
2. To initialize the library
TallyLoginService ls;
public MainPage()
{
this .InitializeComponent();
ls = new TallyLoginService ();
trrm = new TestRequestResponseMgr ();
}
3. To invoke the login page (offline and online mode)
// Handles Online login button click
private void PerformOfflineAuth( object sender, RoutedEventArgs e)
{
PerformAuth( false );
}
// Handles Online login button click
private void PerformOnlineAuth( object sender, RoutedEventArgs e)
{
PerformAuth( true );
}
//Performs login as per mode selected
private void PerformAuth( Boolean pIsOnlineFlag)
{
ls.SetDeveloperMode( true );
ls.SetLoginModeOnline(pIsOnlineFlag);
ls.ShowLoginPage();
}
4. To use the response from the login page
//View authentication success result
private async void ViewAuthData( object sender, RoutedEventArgs e)
{
string user_msg = "" ;
try
{
dict = new Dictionary < string , string >();
dict = ls.GetLoginData();
user msg = "Status : " + dict["Status"] + "\nSession ID :" +
dict["SessionID"] +"\nTallyNET ID :" + dict["TallyNetId"] +
"\nError code & Desc :" + dict["ErrorCode"] + " " +
dict["ErrorMessage"];
}
catch (System.Collections.Generic. KeyNotFoundException )
{
user_msg = "No data found. Please login." ;
}
await ShowMessageDialog(user_msg);

API/Methods |
Purpose |
|
void SetDeveloperMode(bool pIsDevMode) |
To set the developer mode for the library. In developer mode, library points to the test server . |
|
void SetLoginModeOnline(bool pIsOnlineFlag) |
To set the mode (online/offline) in which the library operates. If not set, by default the library operates in offline environment. |
|
bool GetLoginMode() |
T o return the login mode True – Online False – Offline |
|
void ShowLoginPage() |
To show the login page, in the mode set using SetLoginModeOnline API. Used to authenticate Tally.NET User ID against Tally.NET Server. |
|
Dictionary <string, string> GetLoginData() |
To get the authentication data from the library. This provides a dictionary with status, session ID, Tally.NET ID, error code and description. |
|
string GetLoginLibraryVersion() |
To get the current version of the library. |
