Developing Custom Applications with DotNetNuke

Feb 05 2006

The majority of custom applications require security with users, roles, etc. well DotNetNuke is the perfect structure for writing custom applications. Why? you say, well Imagine having a tool which will allow for forms, windows, or LDAP authentication and an impeccable infrastructure for roles/groups allowing module-level security, that's right, not just page level but module level security. Also, DotNetNuke 4 supports ASP.NET 1.1 and 2.0 so you can easily re-use your code without re-inventing the wheel.

In this article I am going to show how, as a .net developer, you can use any .NET language to create custom applications using the DotNetNuke framework by accessing the two basic necessities in any custom application: username and role.


You know how to create user controls in ASP.NET 2.0 and/or 1.1



Step1. Create a UserControl in your project/website:

Step2. Add a Label to the UserControl:

Step 2a. Add a Reference to the “DotNetNuke.dll”

Step3. Now copy and paste this code into your usercontrols Page_Load Procedure (this is in VB.NET)

        Dim mRoles As New DotNetNuke.Entities.Users.OnlineUserInfo
        Dim mUserRoles As New DotNetNuke.Security.Roles.RoleController
        Dim mUser As DotNetNuke.Entities.Users.UserInfo = DotNetNuke.Entities.Users.UserController.GetCurrentUserInfo
        Dim showroles As String = ""
        For Each i As String In mUserRoles.GetRolesByUser(mUser.UserID, mRoles.PortalID)
            showroles += i.ToString() & ","
        Me.Label1.Text = "UserName: " & mUser.Username
        Me.Label1.Text += "
FullName: " & mUser.FullName
        Me.Label1.Text += "
UserID: " & mRoles.UserID.ToString
        Me.Label1.Text += "
Roles:  " & showroles

Step5. Load SmartDNNModule into your portal (follow the instructions that comes with smartdnnmodule)

Step6. Add SmartDNNModule onto a Page

Step7. In the Two Text Boxes type in: “WebUserControl.ascx” then click “Create Module”

Step8. Login in as a user

Step9. Click on the page where you loaded SmartDNNModule

Step10. You now know how to access everything to create a custom application (by exploring the classes that I have shown, you will reveal many useful functions and procedures in the DotNetNuke framework):
