Greetings: I am trying to pass a parameter from one page into another one. How do I do this? Is there a way when someone logs into the application, I do not want them to log in twice. I want the other page to know that this user is already logged in and give him or her OK to use the other page. This is just to prevent multiple log in...

I know that it's said when passing a variable of any integral type like int, double, long double, etc to a function; it should be done by value but I'm curious that from an assembly point(performance-wise or space-wise), wouldn't be there a situation when passing a variable of an integral type with a size bigger than pointers like long d...
In Delphi, if I have a simple class myClass and I pass an instance of it to a function with myFunction( myClass ), which is defined by function myFunction( myObject : myClass ) : Boolean... Will a copy of myObject be made? When I call methods of myObject in myFunction, will the original object be affected and modified too? ...
I need some clarification. Are these two methods the same or different? I get a little bit confused about when the reference to an object passed in a parameter by value is updated and when a new one is created. I know if that assignment creates a new reference, but what about changing a property? Will both of these methods update the...
For SqlDataSource I can configure the external source for the incoming paramater. For example it might be a QueryString, Session, Profile and so on. However I do not have an option to use User as a source. I know that I could provide value for the parameter in Inserting,Selecting,Updating,Deleting events. But I do not think that this is...

Hi, I'm developping a REST API and I need to tranport cryptograms to authenticate the message for each request in a applicative process (MAC encryption from secret keys). I was thinking about putting them in the message header to avoid adding non-data information in the message body which contains the posted/retrieved object (XML or JS...
While debugging some C code with gdb I came across something I've not seen nor heard of before! The compiler (gcc -O0) seems to have created a new type for passing an array of vectors to a function... I think! Have a look at the code and gdb information below: /* The Vector type - nothing unusual */ typedef struct { float x,y,z; } V...

Pass Customer entity to a manager - InsertCustomer(Customer cust) Case 2. Pass each property as a parameter - InsertCustomer(string name, string add...
Does anyone have advice for using the params in C# for method argument passing. I'm contemplating making overloads for the first 6 arguments and then a 7th using the params feature. My reasoning is to avoid the extra array allocation the params feature require. This is for some high performant utility methods. Any advice? Is it a waste o...
For objects or primitive data with a size equal to or less than size of a pointer the most efficient passing method to a function would definitely be by value but the thing is I want to know would be there any tool capable of determining best method of passing objects of classes or primitive data with a sizes bigger than size of a pointe...
