View 4 RepliesI am attempting to create a generic function that the students in my introductory VB .NET course can use to search a single dimension array of a structure.[code]...
My question is: Is there a way to reference the individual structure fields in the array from inside the function? I was trying to make it generic so that the student could simply pass their array into the function - their structure may be named differently than mine and the field names may be different.
I suspect there are other ways to deal with this situation, but I was trying to keep it to just a simple single-dimension array of a structure. I don't think it is possible to do what I want, but I wondered what others thought.

I want to create a license key function for my application.
For example I want in this key to contact 2 values: registered_to, expiry_date.
I want the licence key to be some sort of large string like: 2349ASDGKLASD87ASDGALSDK8ASD80972K.
I would need to create some way to create keys use some sort of algorhithm that decrypts the key and grabs the registered_to and expiry_date values. It also needs to check that the key string has some sort of check digit like credit cards have, so no-one can just type in a few random letters/numbers and it accepts.

View 1 RepliesI have a function Process(data, f) where data is a normal parameter and f is a function needed to process the data (passed as a delegate to Process)
The signature of f is int f(a,b,c), with a, b, c supplied by Process when it calls the delegate.
Up until here, standard delegate usage.
Now, I have a special but common case where I would like to call Process with a constant f function. So I would like to write SimpleProcess(data, k) so that the caller does not need to create a delegate in this case, just pass the constant k (the only information needed).
So I need to dynamically create a constant function, g(a,b,c) which takes 3 parameters (which are ignored) and always returns k. This has to be done within the SimpleProcess function, so that I can then simply call Process(data, g) from within that function, without the need to rewrite the whole Process function for this special case.

I wanted to create a function that checks to see what button has been clicked on the windows form. For example If I had 10 generic buttons that open up different audio files. I would I create one Sub that can verify which button has been selected. I was either going to use a case statement or an if else. I did not want to create one sub for each button since it would be a lot of duplication in code.
