Working with CAML Query using Server OM, CSOM .NET, CSOM REST (JSON/ATOM), WEB Services, Powershell

CAML:-
---------
   <Where>
      <IsNotNull>
         <FieldRef Name='ID' />
      </IsNotNull>
   </Where>
   <ViewFields>
      <FieldRef Name='Title' />
   </ViewFields>

Server OM:-
---------------
try
            {
                using (SPSite site = new SPSite(SPContext.Current.Web.Url))
                using (SPWeb spWeb = site.OpenWeb())
                {
                    SPList spList = spWeb.Lists.TryGetList("Site Pages");
                    if (spList != null)
                    {
                        SPQuery qry = new SPQuery();
                        qry.Query = "<Where><IsNotNull><FieldRef Name=\"ID\" /></IsNotNull></Where>";
                        qry.ViewFields = "<FieldRef Name=\"Name\" />";
                        SPListItemCollection listItems = spList.GetItems(qry);
                        foreach (SPListItem listItem in listItems)
                        {
                            if (listItem != null & listItem["Name"] != null)
                            {

  2. buy twitch followers Deck-building games is a fast-growing genre that is gaining more and more fans around the world. You start out with a lame deck consisting of a few basic cards and then all options are open. It's up to you to find the best combos of cards, add them to your deck and gradually build a "machine" that works better than other players'. It all started with Dominion, then came Thunderstone, Ascention, Nightfall... and now Legendary! But Legendary is much more than a simple deck-building game. Read on to find what's different about it.

  3. https://www.visualaidscentre.com/service/eyes-specialist-delhi/ Horst Wein, who has mentored more than 11,000 soccer coaches in 55 different countries around the world, believes that small sided games are the most essential element in developing youth soccer players. This comes from a man who knows a thing or two about this vital topic - his book "Developing Youth Football Players" is the official textbook of the Spanish Football Federation, and has also been adopted by the Football Federation of Australia, having sold more than 100,000 copies worldwide. Small sided games in Training Coaches should focus more on games rather than drills.

  4. https://www.buyyoutubesubscribers.in/2021/11/20/how-to-earn-money-from-youtube-views/ The second biggest search engine in the world is now YouTube - it's a fact! Yet modern businesses are still unfamiliar with using YouTube to drive more business to their respective websites or sales numbers. That may be because they do not have the knowledge or time to create an effective video marketing campaign. Setting up a YouTube channel that looks professional and reflects the business brand, using that across other social media, researching keywords, producing video with annotation, collecting effective backlinks - all takes time and knowledge.

It's a popularity contest. The more links you have coming to your site from other sites, the more popular the search engines think you are and the closer to the top of the list they will place you.

There are a few huge mistakes you can make when commenting that will get your comments deleted as spam. If this happens it could actually hurt your ranking in Google and it definitely won't get you any new readers. Here is how you do it successfully without looking spammy.

  7. https://www.visualaidscentre.com/lasik-eye-surgery-in-delhi/ There is a new trend in the world of gaming called game swap, also known as game sharing. It is a concept that has been used over and over again among friends and family, but is starting to branch out over the Internet. The idea behind game sharing is you essentially take the games that you have but don't really play anymore and see if you can trade for games that others have that you want.
