问题 I have a code example from KendoUI. public ActionResult Customers_Read([DataSourceRequest]DataSourceRequest request) { return Json(GetCustomers().ToDataSourceResult(request)); } private static IEnumerable<CustomerViewModel> GetCustomers() { var northwind = new SampleEntities(); return northwind.Customers.Select(customer => new CustomerViewModel { CustomerID = customer.CustomerID, CompanyName = customer.CompanyName, ContactName = customer.ContactName, // ... }); } This example works fine.

问题 I'm writing a bash script called 'run' that tests programs with pre-defined inputs. It takes in a file as the first parameter, then a program as a second parameter. The call would look like ./run text.txt ./check for example, the program 'run' would run 'check' with text.txt as the input. This will save me lots of testing time with my programs. right now I have $2 < text.txt > text.created So it takes the text.txt and redirects it as input in to the program specified, which is the second

问题 I am trying to us the DateAdd function of SQL in my Query. The problem is when I use a parameter to set the second arguement, the number argument I get an error which will say something like this: Failed to convert parameter value from a Decimal to a DateTime While if I enter it parameterless, i.e hardcode an Int, it works fine. This works: SELECT FieldOne, DateField FROM Table WHERE (DateField> DATEADD(day, -10, GETDATE())) while this does not: SELECT FieldOne, DateField FROM Table WHERE

问题 When reading documentation on functions from external libraries of different kinds I have always seen the documentation state that a variable has to be [IN/OUT]. Could someone give me a detailed understanding on how [IN/OUT] relates to parameters of a function being passed by reference or by value. Here is an example of a function I have come across that tells me it needs an [IN/OUT] parameter: Prototype: ULONG GetActivationState( ULONG * pActivationState ); Parameters Type: ULONG* Variable :

问题 I am reading C Programming: A Modern Approach by K.N.King to learn the C programing language and the current chapter tells about functions, and also array parameters. It is explained that one can use constructs like these to express the length of array parameters: 1. void myfunc(int a, int b, int[a], int[b], int[*]); /* prototype */ void myfunc(int a, int b, int n[a], int m[b], int c[a+b+other_func()]) { ... /* body */ } 2. void myfunc(int[static 5]); /* prototype */ void myfunc(int a[static
