How can I pass a function address?

I am trying to pass a function (method) address to a user control to
associate with an event.

The small user control which sends events is contained in a larger user
control group which is in turn contained in the main application. I need the
event handler to exist at this top level in the application, and so I'm
trying to somehow let the small control (two layers down) know the address
of this handler, so that the function is called.

I thought I could have the main application pass the address of the top
level event handler to the user control group, which could then pass it on to
the small controls. However when I try to pass the function name as a
parameter from the top level the compiler is asking for parenthesis - which
obviously won't do what I want.

Perhaps I am going about all this the wrong way anyway.

Any ideas?

Read about delegates. C# doesn't have function pointers. Delegates supply
more or less the same functionality, but in a cleaner way.

Thank you - that's what I'll do.

Hi folks, I would be interested to hear peoples views on whether or not 'pass by reference' is allowed when using a Web Service method. The thing that troubles me about pass-by-reference into a WebService is that essentially we are passing an address of an object which resides on the 'local machine' i.e. a local machine object address. Surely when the WebService method is called and run 'on the server', the reference type will be...

I wrote a function foo(int arr) and its prototype is declared as foo(int arr); I modify the values of the array in the function and the values are getting modified in the main array which is passed also. I understand that this way of passing the array is by value and if the prototype is declared as foo(int *), it is by reference in which case the value if modified in the function will get reflected in the main function as well. I dont...

I've read that C allows two ways to pass information between functions: o Pass by Value o Pass by Reference I was talking to some C programmers and they told me there is no such thing as pass by reference in C since you are just passing an address (or a pointer value address I guess?). So I was wondering is this correct?

I have problem understanding pass by value and pass by reference and want to how how they are or appear in the memory: I had to get my basics right again. I create an array and try all possible ways of passing an array. In the following code, fun1(int a1) - same as fun1(int* a1) - where both are of the type passed by reference. Inside this function, another pointer a1 is created whose address &a1 is different from that of the passed...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
