Hi All,

Here is a tested working C# code sample I have just "cooked" after digging through DNN sources - I tried but I didn't find something like that on Internet therefore I hope this sample will be helpful to the folks starting DNN custom modules development:

 /// <summary>Constructor</summary>
public class MyDNNContext
{
    private DotNetNuke.Entities.Portals.PortalSettings _portalSettings;
    private DotNetNuke.Entities.Users.UserInfo _userInfo;
    private DotNetNuke.Entities.Tabs.TabInfo _tabInfo;
    private DotNetNuke.Services.Tokens.TokenReplace _tokenizer;

    /// <summary>Constructor</summary>
    public DNNModuleRunningContext()
    {
         _portalSettings =
                 DotNetNuke.Entities.Portals.PortalController.GetCurrentPortalSettings();
         _userInfo = _portalSettings.UserInfo;
         _tabInfo = _portalSettings.ActiveTab;

         _tokenizer = new DotNetNuke.Services.Tokens.TokenReplace();
         _tokenizer.User = _userInfo;
         _tokenizer.AccessingUser = _userInfo;
         _tokenizer.DebugMessages = false;

    }

    /// <summary> Version Info </summary>
    public string VersionInfo
    {
        get
        {
            return string.format("version ={0}, type = {1}, name = {2}",
              DotNetNuke.Application.DotNetNukeContext.Current.Application.Version,
              DotNetNuke.Application.DotNetNukeContext.Current.Application.Type,
              DotNetNuke.Application.DotNetNukeContext.Current.Application.Name);
        }
    }

    /// <summary> Connection String</summary>
    public string ConnectionString
    {
        get
        {
            return DotNetNuke.Common.Utilities.Config.GetConnectionString("SiteSqlServer");
            //OK also - return DotNetNuke.Common.Utilities.Config.GetConnectionString();
        }
    }

    /// <summary> Current Portal Id</summary>
    public int PortalId
    {
        get { return _portalSettings.UserId; }
    }

    /// <summary> Current User Id</summary>
    public int UserId
    {
        get { return _portalSettings.UserId; }
    }

    /// <summary> Current User Name</summary>
    public string UserName
    {
        get
        {
            return _userInfo.Username;
        }
    }

    /// <summary> Return True if current user is SuperUser</summary>
    public bool IsSuperUser
    {
        get
        {
            return _userInfo.IsSuperUser;
        }
    }


    /// <summary> User Roles names array</summary>
    public string[] UserRoles
    {
        get
        {
            return _userInfo.Roles;
        }
    }

    /// <summary> Current Tab Id</summary>
    public int TabId
    {
        get
        {
            return _tabInfo.TabID;
        }
    }

    /// <summary> Current Tab Name</summary>
    public string TabName
    {
        get
        {
            return _tabInfo.TabName;
        }
    }


    /// <summary> Current Tab Name via [Tab:TabName] token</summary>
    public string TabName1
    {
        get
        {
        return _tokenizer.ReplaceEnvironmentTokens("[Tab:TabName]"); }}

    /// <summary> Current UserName via [User:Username] token</summary>
    public string UserName1
    {
        get
        {
            return _tokenizer.ReplaceEnvironmentTokens("[User:Username]");
        }
    }

    /// <summary> Get Current user profile property by property name</summary>
    public string GetUserProfileProperty(string propertyName)
    {
        return _tokenizer.ReplaceEnvironmentTokens(
               string.format("[Profile:{0}]", propertyName));
    }
}
 

Thank you.
