How to secure Crystal Report ?

To integrate Visual Guard in your application you have to:

• Add the assemblies of Visual Guard as references of your project.
• Integrate Visual Guard in the code of your application.
• Create a Visual Guard repository and declare your application by using the
  Visual Guard console. This repository will contain all security items (users,
  roles, permissions …) of your application.
• Generate the Visual Guard configuration
  files by using the Visual Guard console. These configuration files will be
  needed to connect your application to the repository.
• Grant read/write permissions to the repository.

Referencing Visual Guard assemblies

• Opens the solution of your project in Visual Studio.
• In the solution explorer, expands the project node.
• Right-click the Project node for the project and select
  Add Reference from the shortcut menu.
• In .Net tab, select the 4 assemblies
  1. Novalys.VisualGuard.Security
  2. Novalys.VisualGuard.Security.<ProjectType> (WinForm,
     ASP.net),
  3. Novalys.VisualGuard.Security.<RepositoryType> (Files, SQLServer or Oracle)
  4. Novalys.VisualGuard.Security.<ApplicationFrameworkType> (Depending on type of application’s framework, whether .NetFramework or .NetCore)
• And, then click the Select button, and then click the OK button

Note
In the list of assemblies, Visual Studio can display different versions of the Visual Guard assemblies. You must select the assembly corresponding to the version of the framework used in your project.

Note
You must add either Novalys.VisualGuard.Security.NetFramework or Novalys.VisualGuard.Security.Core (Depending on type of application’s framework)

• Novalys.VisualGuard.Security contains the main Visual Guard classes.
• Novalys.VisualGuard.Security.Files contains the classes needed to access
  to a file based repository.
• Novalys.VisualGuard.Security.SQLServer contains the classes
  needed to access to a repository stored in a Microsoft SQLServer database
  (SQLServer 2000 or higher). Available only in Visual Guard Enterprise Edition
• Novalys.VisualGuard.Security.Oracle
  contains the classes needed to access to a repository stored in an Oracle
  database (8i or higher). Available only in Visual Guard Enterprise Edition
• Novalys.VisualGuard.Security.WebForm contains the classes
  needed to ASP.Net application. You must reference this assembly in ASP.Net
  WebSite or ASP.Net WebService project.
• Novalys.VisualGuard.Security.WinForm contains all classes based on WinForm
  control. This assembly is needed only if you use the forms provided by Visual
  Guard to authenticate, change a password or select a role. If you want to use
  your own form you do not need to add a reference to this assembly.
• Novalys.VisualGuard.Security.NetFramework contains all classes required to support .Net Framework applications.
  This assembly is needed only if you want to integrate Visual Guard in .net framework applications.
• Novalys.VisualGuard.Security.Core contains all classes required to support .Net Core applications.
  This assembly is needed only if you want to integrate Visual Guard in .net core applications.

private void Form1_Load(object sender, EventArgs e)
{
    SqlConnection SQLCon = new SqlConnection(Properties.Settings.Default.visualguarddb_NBAConnectionString);
    try
    {    

        SQLCon.Open();

        DSVG ds = new DSVG();
                                SqlDataAdapter ada = new SqlDataAdapter("select * from VG_Log", SQLCon);
        ada.Fill(ds, "VG_Log");


        //Create a parameter
        ParameterFields pfields = new ParameterFields();
        ParameterField pfield = new .ParameterField(); 
        ParameterDiscreteValue disvalue = new ParameterDiscreteValue();


        // Parameter Name 
        pfield.Name = "UserName"; 

        // Iniatialise the Parameter Value 
        disvalue.Value = User;/initialise the parameter with the valuean>
        pfield.CurrentValues.Add(disvalue);

        //Add the parameter in the list of parameters
        pfields.Add(pfield);

        //Add the parameters list in the ParameterFieldInfo of the report viewer
        crystalReportViewer1.ParameterFieldInfo = pfields;

        vgEventReport.SetDataSource(ds);

        crystalReportViewer1.ReportSource = vgEventReport; 

    }
    catch (Exception)
    {
        throw;
    }
    finally
    {    
        SQLCon.Close();
