Sorry, forgot about the new() keyword. Pete's response describes how to use it.
Take care,

Did you perhaps for get to escape a < in your code?

This will do it.
public class Category : RESTResource<Category>
{
}
public class RESTResource<T> where T : RESTResource, new()
{
public <T> Get()
{
T item = new T();
return item;
}
}

No problem. I hope it helped.

I'm developing a windows application in C# with crystal reports. In one of my reports I deisplay passenger list comes by cruises. I group it by cruise no. I want to display group footer with total no of passengers by their nationality and grand total, something like this,
Malaysia 10
Singapore 15
Thailand 10
Total 35
and I need to do the same thing at the report footer as well with totals of groups. Can anybody tell me how to do it.

Dear All,
I am making a NMS (Network Monitoring System) and have accomplished to query windows based computers via the WMI (which by the way is very helpful).
Now my target is to embed the SNMP functionality inorder to achieve status of Managed Network devices (such as switches and routers...) to be displayed into my software.
I have seen codes at CP but there is a wrapper class that available but I am looking for is making it right from the scratch in C#
Please Advice
Thank you!

ive got a very simple program set up in vs 2003 written in c#...
it includes a ref to system.diagnostics and uses process.start(@"c:/meh.bat") to try and run a batch script... the code runs without error, and i see the console window flash before me, but it seems as though nothing happened... so to test it out i setup the batch script to run notepad... i double click on the script through windows, and there's notepad... i run the program which SHOULD run the batch script, and nothing happens.... anyone have a clue as to what might be going on?

Didn't you want a backslash rather than a slash?
|
|
|
|

yes, im sure its right in the code though, i was just trying to get the point across and i dont have the code in front of me
when i made it just to be safe i went to start>run>browse, clicked the batch script then copied the exact text from the run window to be sure it was err free

The window closes as soon as the executable exits.
You can add a System.Console.ReadLine() to the end of your app so it stays open until you press return.

How do you make it so an if statement has a lot of things to match? It's hard to explain, but instead of '&&', is there a way to make it so you can have a bunch of if's to follow? I hope you understand what I mean... Thanks in advance, M.S.
|
|
|
|
|
You mean like this?
if ( a )
{
if ( b )
{
...
}
}
|

You can do one of three things:
1 - if (x == 0 && y ==1 && z == 2)
2 - if (x == 0)
{
if(y == 1)
{
if ( z== 2 )
{
3 - if (ValidateForm())
{
}
where you have a lot of stuff to check and you factor it into a function ( this works only if the things you are validating are member variables )
If you had lots of different ifs, as in
if (x == 0 )
{
}
else if (x == 1)
{
}
else if (x==2)
then you'd want a switch statement. But, if you have a lot of things to check, there's no way around that you need to specify what they all are.

The long and short of it is that you can chain together as many expressions as you like with &&'s and ||'s.
I'd recommend picking up an introductory C# book - there are a number of good ones. Jesse Liberty's "Learning C#" is a good one, or you might find the Head First C# book interesting to read - it isn't your standard C# text. Apress has some good ones too. I have several books on the subject and each provides a different perspective.
I think that you'd really benefit by getting one of these books and working through it. Most have exercises, and those are helpful. There are a bunch of great folks here at Code Project who can answer questions, but you're not going to learn the language nearly as well as if you invest some time with a good text - your question indicates that you are new to the language and probably haven't worked through an introductory text, because just about any good introductory text would have provided the answer to that question and TONS of others you are likely to have along the way.
.NET development, and programming in general, is a journey and NONE of us has it all figured out - if you'll invest the time upfront with a good text on the language, and then experiment along the way, read the MS-provided help pages, you'll likely be quite capable at developing C# apps in a reasonable period of time. Of course, when you are stumped on a program, there are a bunch of folks here that would be happy to take a look at the code snippet and respond. At least that has been my experience.
Good Luck!
It isn't enough to do well in life.
One must do good when and where one can.
Otherwise, what's the point?

No, actually, I mean (though this isn't correct, something close to the idea), like this:
if (condition)<br />
|| condition<br />
|| condition <br />
and so on...
or is that what the || operator does?
|
|
|
|
|
Like this?
if ( a )
{
...
}
else
{
if ( b )
{
...
}
else
{
...
}
}
|
|
|
|
|
No, I mean having more things that have to be true (for example) in the if statement? I'm sorry, it's complicated...
|
|

Only because you're not making sense. Try giving a real world example, so we can work out what you mean.

Is that what he means ?
MasterSharp, this is why we discouraged you from writing owner drawn controls yesterday. Not because we don't want to help, but because you need to grasp the basics first. If this is what you meant, I urge you again to buy a book on C# and work through it, so you cover these sort of elementary gaps in your knowledge and build a firm foundation you can build on.

I don't follow. condition is different every time ?
if (x == 1 || y == 2 || z == 3)
will succeed if only one of those statements is true. && requires they are all true.

How many '&&'s can you use, is what I mean. I guess that what it boils down to.

Until your & key wears out, and even then you can copy-and-paste.
