Normally, we run code under elevated previleges that takes System User account in created by modified by. If we want to reflect Created By/Modifed by with logged in user, you have to specify UserToken while opening site.

SPUserToken loggedInUserToken = SPContext.Current.Web.CurrentUser.UserToken;

SPSecurity.RunWithElevatedPrivileges(delegate()
{
using (SPSite objSite = new SPSite(SPContext.Current.Web.Url,loggedInUserToken))
{
using (SPWeb objWeb = objSite.OpenWeb())
{
objWeb.AllowUnsafeUpdates = true;
SPListItem lstItem= listItemCollection.Add();
lstItem[“Foo”] = “Bar”
lstItem.Update();

As a student, I always used to wonder why do I have to pay for learning / developing on Microsoft platform if my development is not generating any revenue. And to be frank, all of  us(students) used to rush to nearest Pirated CD vendor or try Peer to peer networks to get cracks. But, It looks like Microsoft has listened to our dilemma and Things have changed now.

Some of the cool development tools available are:

• Visual Studio 2008 Professional
• SQL 2005 Developer
• Windows Server 2003(For sharepoint development)

It is called DreamSpark.

If you are student, Getting software like Visual studio 2008 is very simple,  Rush to nearest Microsoft Parnter location, Show your college identity card and collect your licensed copy of the software

How to package skin?
ASCX / html+xml file represent skin
Create associated thumbnail to act as preview for this skin when uploaded
Zip all resources(css/images/thumbnail/skin)

Diff between ASCX and HTML skin?
Html skin facilitates designers to create/modify layout in their favourite tool(dreamweaver). At the same time it requires xml file for managing attributes of skin object
Everytime you parse html skin, it generates ASCX.
This ASCX skin gets inserted into Default.aspx page[SkinPlaceholder]

How to upload new skin?
Go to host > Skin, upload new skin for portal.

Do I need container or just skin is sufficient?
Container allows you to define rectangular/rounded rectangle around content pane and also actions menu.

How do I add menu?
Explore DNNMenu

How do I add external stylesheets?

Having read simple tutorial Dotnet and opensource: better together on publishing blog post from word 2007, I could not resist myself experimenting it with my personal blog – msqr.wordpress.com.

Let’s see how it goes.

Many times we are required to hook event handler with the element through javascript. Main problem we come across during this time is how to pass arguments to registered event handler.

Here’s the handy function that returns Element triggered event handler

function GetEventSource(evt)
{
var ie_var = "srcElement";
var moz_var = "target";

if(window.addEventListener)
{
return evt[moz_var];
}
else
{
return evt[ie_var];
}
}

//Register event handler:
if(window.addEventListener){ // Mozilla, Netscape, Firefox
lnk.addEventListener('click', CallDoPostBackMM, false); }
else { // IE
lnk.attachEvent('onclick', CallDoPostBackMM);
}

function CallDoPostBackMM(evt)
{
var lnk= GetEventSource(evt);
//Now, you have access to lnk element:
//you can retrieve navigateURL, href, set javascript and so on.
}
