c# - How is "using" statement supposed to work? -


I am trying to take advantage of the statement using in the following code: Uri Uri = new Uri ("http: // localhost: 50222 / odta"); Var Container = New Course System. Container (Yuri); CourseServiceRef.NotNeededededededTempUser = New coursecaref.noted () {email = model. Username, Username 1 = Model User name}; Container.AddToNotNeededs (newTempUser); Container.SaveChanges ();

Although it does not compile. Why?

- does not match - for those objects that implement it so that they can block the code Automatically resolved at the end of: 

 using  (var toto = new MyDisposableClass ()) {// do stuff}   
 if any This interface of your classes implements the interface (or whatever it happens), you can use the syntax above to call the  disposable ()  method. You can use this int Can not use the  use  blocks for objects that do not apply the ruffs, it will not be compiled simply.  
 Basically it will be like the following:  
  var toto = New MyDisposableClass (try) {// do stuff} Finally (if (toto! = Null) (( IDisposable) toto) Dissociate ();}   
 The only difference here is that in the first scenario, using the  toto  scope of  using  The end of the block dies.

I was trying to use the program to use mifrewan on 4 node clusters. Distributing node 0 data in nodes 1, 2 and 3. In the program, from '90 'to variable values ​​of' dior 'to be calculated. Therefore the node is distributing data and collecting results in an omitted fashion (for different values ​​of var 'dir') when do {*******} Whereas (dir Loop is given, Mippun is hanging, and no output is found. But when I comment on two {*******} (dir The loop output is obtained for the initial value of variable dir dir = -90 ), and that output is correct. The problem occurs when the loop is given. Can anyone help me in solving this problem. #include "mpi.h" int main (int argc, char * argv []) Float dir = -90; Int rank, nanoprakash; MPI_Status status; MPI_Init (& amp; argc, & argv); MPI_Comm_rank (MPI_COMM_WORLD, & amp; Rank); MPI_Comm_size (MPI_COMM_WORLD, & amp; numprocs); If (rank == 0) {/ / data to begin / / (dest = 1; dest ...

python - Apply coupon to a customer's subscription based on non-stripe related actions on the site -

I can not find anything in the source about using coupons after subscribing to a user's plan. Is it possible to use a coupon to credit a user's membership after initial subscription? If not, what is the best option? Specifically, I want to give a user 100% coupon for that month, when they take 5 [site specific actions]. This is possible, but may not be the best idea. Coupons are currently applied to the stripe, then apply again at the customer level and each client can have a single coupon. So if you are already offering discounts to the coupon, then the customer who is currently in the present will also give up. It also means that if you are using a recently-added multiple subscription capacity, then all of the user's subscription will be ready for the month. Coupons can be set to "Once", only once (as the only name) can be used by any customer, so if this credit can earn more than once, You will have to maintain a 100% discount coupon continuousl...
