SPWeb.Users Vs SPWeb.SiteUsers

Hi,
You will have to get the instances of users who are in your site in some situations. Then make sure that you are using the proper property to get the details.

SPWeb.Users returns the users that are added to that particular subsite only. It will not list the users inherited form parent site.

SPWeb.SiteUsers returns all the users.

Same with SPWeb.Groups and SPWeb.SiteGroups.

Run with elevated privilages............

Hi,
Here I am listing some of the things that you have to take care when you are working with SPSecurity.RunWithElevatedPrivilages.
1) Don't get the instances of SPSite and SPWeb from the context variables.
Eg: If you have RunWithElevatedPrivilages in Event Handlers. Don't get the instances of sitecollection and site from properties varibales directly.

Don't Use
i.e SPSite site=properties.site;
SPWeb web= properties.openweb();
Use

SPSite site = new SPSite(properties.SiteId)
SPWeb web = site.OpenWeb(properties.RelativeWebUrl)

Because the first code returns the instances with the current user prevelages. so, eventhough you are working with elevated privilages you will get access problems with those instances.

Reset the IIS After updating the DLL for event receiver

Hi ,
Today, when I was working with Event Receivers for Sharepoint Lists. I got lots of troubles in debugging the code.
Actually, I had writen the code and installed DLL in to GAC. And, added the w3p process to debug the event receiver.
When I changed the code, I forgot to reset the IIS. That did not show me the debigging in a wrong way. Because it is still using the old code.

So, better reset the IIS when you make a new DLL.

NOTE:- Everyone know that we should reset when we install a new DLL we should reset IIS. But some people like me may forget or neglect it. So, Remember my case and don't forget to reset the IIS.
