When I write public events for my business objects, I've adapted the habit of always passing the instance as "sender as Object", in addition to additional specific parameters. I just asked myself now why am I not specifying the class?
So for you with more experience; Do you ever pass the distinct class as sender in an event? And if so, what are your decision criteria for when this is ok/not ok?

I am making a program that can send emails by the click of a button. But the problem is that it takes a long time to send the email.When the send button is pressed it declares the smtp server, credentials and everything. But I am wondering if there is a way to have the smtp server, credentials, port and everything already declared and then as soon as the send button is clicked it sends right away?
EDIT: I am going to try declaring that information at form1_load.
EDIT: It didn't work, even when I tried changing private form1_load to public form1_load .

We are trying to identify the best archtecture while using a ORM like LINQ to SQL. The archture we are defining is for sort of framework that other applications will access either trough directly referencing the DLL or through a webservice. We have .NET apps and PHP apps.The possibilities are: Multiple data contexts: Separting the database into units of work and create separate contexts for each one.
Pros:
Easy of use
Classes will be broken into different namespaces
Smaller domain to maintain
Cons:
Objects have to be duplicated if
related, creating maintenance hell
Objects cannot be passed between context, creating the need for another hit on the data base Single data context: All tables, views, procedures, reside in the same huge context.

I have a large string in which I need to replace specific strings with other values. For example, within this string I might see the following characters: [[sub id=5]]. I am trying to replace those substrings with values, pulled from a table and based on the id. What would be the simplest way to accomplish this. My first thought was to loop through and examine each character and note their positions when they match the pattern. I would then have to identify the id. That would be fairly complicated, however, and there must be a better way.

I need to identify an ID number and a password. Like this,(Form1) there's a two textboxes, one is the ID number and the second one is the Password, when I enter the two it means i Log-in, the system needs to identify if the ID number and the password is registered in mySQL, then if it is registered a message box will appear "You are log-on" and a form will show (form2) in 10 to 15 seconds that is having the information of the student, then it will automatically close then it will go back to the form1 which the another user will log-in again.
(this is Form1 too) then here is my second problem, like what i said in the first problem, the program needs to identify that the student is already log-on the school and he is going to log-out, (like this, system is going to identify that the id number and the password is already declared on the first form, so it will be the log-out code, then a message box will appear "You are Log-out".
(Form3) then here is my third problem, i need to identify how many people is inside the campus and not going out on the campus. The person or student that is not logging-out on the program or the system will be count when i click the Button 'Count' and the number of student inside the campus will be display in a 'Label'(it will be inserted also or having record on mySQL tableInside).
('Form4') then my fourth problem is the system needs to identify how many students did log-in on the campus. Or the system will identify how many person input their ID Number and Password on the first form ('Form1', it will be inserted or having record on mySQL tableLog).
