I have a generic event handler:
public delegate void EventHandler<TEventArgs>(object sender, TEventArgs e);
public class EventArgs_Generic<T> : EventArgs
{
private T _TargetObject;
public T TargetObject
{
get { return _TargetObject; }
}
public EventArgs_Generic(T Target)
{
_TargetObject = Target;
}
}
How do I list this in an interface? Something like...
event EventHandler<T> ....
Thanks
Everything makes sense in someone's mind

You can do this:
public interface IFoo<T>
{
event EventHandler<T> Bar;
}
Or you can just make the generic type concrete in the interface:
public interface IFoo
{
event EventHandler<int> Bar;
}
Depending upon your circumstances.

Say, I have
DataGridviewCheckBoxCell cell object. I can select/deselect it by doing
cell.Value = true /
cell.Value = false . This works until user manually selects/deselects some checkbox - after that this checkbox stops changing after assigning a value. What could be the reason for that?

Assuming you've bound the grid to a datasource, you have to modify the datasource, not the cell values.

There's a "Database" forum further down the list of forums on the left.

Not a C# question, unless they've completely re-designed c# in the last few minutes.

Wow, you are here for more than 8 years, have already posted more than 500 messages and still haven't figured out, how to find the right forum for a question.

In SQL Server, I was doing this in the stored procedure:
param_record_id int OUTPUT
then I :
set param_record_id = scope_identity()
how can id o the same in mySQL stored procedure?

And how is this a C# question?

Hopefully this one can help. How to get OUT parameter from MySQL
 It didn't even click in me that I wasn't in the db forum... Ignore my answer and put the question in the right place...
I wasn't, now I am, then I won't be anymore.

Hi,
I have an appointment software using C# WinForm and I want to send alerts (SMS & Emails) through SMS gateways and email to the customers..
I want to know what's best...
1. Send the alert directly from the PC? this will require an internet connection on the PC.
or:
2. Send the alerts to the database on the server and make it in queue? this will not require internet connection to be enabled on every PC.
what do you think?

This is entirely up to your clients requirements. Personally, I'd go for a more centralized solution, but have no idea what your specs are, the design of the application, what the load is going to be, what the clients restrictions are, ... In other words, you should be asking your client this question, not us.

my client doesn't talk IT
I have dell server and dell clients
it's a medical software for a clinic with let's say 100 appointments per day
My backend is MySQL and I am using C#.
if you were given this what you will do? will send it from the PC or queue it on the server?

I alreay told you what to do. Interviewing the client and gathering detailed requirements is what I'd be doing. Guessing at what the client wants will only get you fired, or not paid when the job is "complete".
I also already told you what my preference would be, but then, I'm not the one coding the app and I'm not the one who's going to pay for it.

hi
I have homework but I cant solved because I cant install oracle in pc (pl/sql)
this is question print the max salary of emp by function u created in pl/sql
and my teacher want answer in Thursday

Why can't you install oracle?
Real men don't use instructions. They are only the manufacturers opinion on how to put the thing together.
|

Oh, there can be quite a few reasons for not being able to install Oracle or getting it running. Have you ever tried it? Then you'd remember the fun with it: e.g. no spaces in path names, extreme requirements for memory and swap files, very complicated processes for creating table spaces, users, schemas, etc. Really stuff from the last millennium, but you need latest hardware!
By the way, there is an "I hate Oracle club": http://forums.thedailywtf.com/forums/17.aspx[^]

A few things.
1. We don't do people's homework for them. We aren't trying to pass the course.
2. What has this got to do with C#?
3. Surely you have labs at the school where you can go and try this out.
4. If you have a PC, you can install a cut down version of Oracle.

Not necessarily, I can tell you this from first hand experience here. It is very different to the UK....

I suspect that your teacher expects you to write the function based on the information you have learned in the class. You should not need to install Oracle unless you actually have to test the function as well.
Just say 'NO' to evaluated arguments for diadic functions! Ash

As the others have said, we don't do homework questions here. If you are having problems getting Oracle installed, I suggest you try the DB formum here, or one of the Oracle specific forums elsewhere.

Hi,
I'm running my ASP.Net application in 32 - bit, 4 GB RAM server. As because I'm getting large number of hits to my application I'm planning to move to 64 - Bit , 8 GB RAM (running in Virtual Environment).
- Will IIS utilize more RAM and handle large number of hits ?
- What would be the maximum concurrent users that the server can cater?
Thanks in advance ..
