Fix Visual Studio 2013 Error “No exports were found that match the constraint”

When loading an existing universal Windows App solution, I noticed that the shred project failed to load in Visual Studio 2013. When creating a new one, I ran into an error as shown below.

No exports were found that match the constraint: ContractName Microsoft.VisualStudio.Text.ITextDocumentFactoryService RequiredTypeIdentity Microsoft.VisualStudio.Text.ITextDocumentFactoryService

I solved this problem by clearing Visual Studio Component Model Cache.

Just delete or rename this folder: %AppData%\..\Local\Microsoft\VisualStudio\12.0\ComponentModelCache

SQL query to LinQ sub query simple tricks

I have the following SQL query and I will change it in LINQ, Simple query but have to do in one query to reduce database call. Here is the SQL query

select * from td_Accountline 
where 
    BonusPlanID = 1
    and Amount > 0
    and Ord_Sub_ID like '%SMPORD%' 
    and MONTH(Created) = 11
    and YEAR(Created) = 2013  
    and Ord_Sub_ID not in (
        select Ord_Sub_ID 
        from td_Accountline 
        where 
            BonusPlanID =3 and
            Ord_Sub_ID like '%SMPORD%'
    ) 

My LinQ query is bellow, I have used 'let'. The 'Let' keyword allows storing the results of a query which can be used in a subsequent query.

  var accountdata = from acc in currentDatabase.td_Accountline 
                    where
                    acc.BonusPlan.BonusPlanID == 1
                    && acc.Amount > 0
                    && acc.Ord_Sub_ID.Contains("SMPORD")
                    && acc.Created.Value.Month == 11
                    && acc.Created.Value.Year == 2015
                    let accNot = from accN in currentDatabase.td_Accountline 
                                 where
                                 accN.BonusPlan.BonusPlanID == 3
                                 && accN.Ord_Sub_ID.Contains("SMPORD")
                                 select accN.Ord_Sub_ID
                             where !accNot.Contains(acc.Ord_Sub_ID)
                    select acc;

Happy LinQ Sub Query :)

Asp .net MVC hidden field can't set value using jquery [Solved]

My hidden field is declared like this:

@Html.HiddenFor(model => model.Token, new { ClientIDMode = "Static" })

Then assign the value bellow way in hidden field

How to find the Second value (could be largest or lowest) from a table.?

I have One table with StatusIDHeld in "UserStatusHistory"Table with this column userid,StatusIDHeld and statusChangedOn. One customer could be multiple StatusIDHeld . I am finding out just previous one StatusIDHeld that mean the second StatusIDHeld which just before he had hold.

To be able to get 1., 2. or n-th record depending on sort order, use ROW_NUMBER() function.

                        SELECT StatusIDHeld 
   FROM
   (
    SELECT StatusIDHeld, ROW_NUMBER () OVER(order by statusChangedOn DESC) as RowNo
    FROM UserStatusHistory where userid= 1037146 
   ) AS t
   where t.RowNo = 2

Happy Query .....

SQL SERVER – Simple Example of Cursor with update table

A cursor is a set of rows together with a pointer that identifies a current row.

DECLARE cursor_activatedOnEmpty CURSOR FOR SELECT userid, statusid,RegisteredOn, activatedOn, RealActivationDate FROM UserProfile where statusID=1330 and  activatedOn is null; 
DECLARE @userid INT;
DECLARE @statusid INT;
DECLARE @RegisteredOn Date;
DECLARE @activatedOn Date;
DECLARE @RealActivationDate Date;
DECLARE @PreviousStatusID INT;
OPEN cursor_activatedOnEmpty;
FETCH NEXT FROM cursor_activatedOnEmpty INTO @userid, @statusid,@RegisteredOn, @activatedOn,@RealActivationDate;
WHILE @@FETCH_STATUS = 0  
BEGIN    
 
 SET @PreviousStatusID = (select top 2 StatusIDHeld from dbo.UserStatusHistory where userid=@userid order by statusChangedOn DESC)  
       if (@PreviousStatusID=1325)
       update UserProfile set activatedOn=@RegisteredOn where userid=@userid

       FETCH NEXT FROM cursor_activatedOnEmpty INTO @userid, @statusid,@RegisteredOn, @activatedOn,@RealActivationDate;
END;
CLOSE cursor_activatedOnEmpty;
DEALLOCATE cursor_activatedOnEmpty;

Happy Cursor!!

Files has invalid value "<<<<<<< .mine". Illegal characters in path [Solved]

First you have to remove any characters like "<<<<<<< .mine" or similar from the file that you will see in your project Folder.

If you don't find "<<<<<<< .mine" this one then you have to search in bollow this file
.csproj.FileListAbsolute.txt

which contains a list of all the paths and recompile ...it worked for me :)

C# multiple value return from single function

There are a number of ways to return two object from one function. You can class or structure and another one as out parameter. Alternatively, you can use generic type with two members. Such type, in particular, it Tuple:

#I am using Tuple to returns 2 datetime value(fromDate , toDate )

  public Tuple GetDates()
   {

          DateTime fromDate = DateTime.Now;
          DateTime toDate = DateTime.Now;
          int year = Convert.ToInt32(this.ddlQYear.SelectedItem.Value);

            if (Convert.ToInt32(ddlQ.SelectedItem.Value) > 0)
            {
                int month = Convert.ToInt32(ddlQ.SelectedItem.Value);
                fromDate = new DateTime(year, month, 1);
                if (month == 12)
                    toDate = new DateTime(year + 1, 1, 1);
                else
                    toDate = new DateTime(year, month + 1, 1);
            }
            return new Tuple(fromDate, toDate);
   }
===========Call this function bellow way==============================
            
DateTime fromDate = GetDates().Item1;
DateTime toDate = GetDates().Item2;

#Another way use "out" keyword:

 public static int GetDates(out DateTime FDate, out DateTime TDate)
   {
            DateTime fromDate = DateTime.Now;
            DateTime toDate = DateTime.Now;

           // Calculate your date

            FDate=fromDate ;
            TDate=toDate
     

         return 1;
   }

Hope that this helps!!
