Hej!
We are working on a ASP site that is connected to a database(Access)(On the Same SERVER).
We are also developing a Server/Client program. This Server(C#) will have to be connected to the database one way or the other.
It have to react when a change is made to the database.
We have then thougt of the ASP to trigger the event at the Server(C#), is there any way to do this easy? The Server will be located at the same SERVER as the ASP site.
One other thougt is to let the Server program look in the database for changes, but only one can be connected to the database and by this the C# server will not be able to read it thou the ASP site is working against it.
Pleas help!
Best Regards
Jimmy

Do you mean ASP, or ASP.NET ?

That's a real shame ( on many levels, I feel sorry for you  ).
I'd say your best bet is COM. From memory, the mechanism for a COM object to call it's own is called 'connection points' ( this is deep, dark memory banks we're accessing though ), I dunno if they work with C#/COM interop, but clearly COM is the thing that ASP and C# can both use to talk to each other, so I reckon that's where your answer lies, unless you want to do something really ugly like have the C# code poll a file or table to find out when changes occur ( I am not suggesting this is a good idea ).
Is the ASP site legacy code ?

Yeah its a shame, but it would take to much time to tech us ASP.net right no.
COM sounds intressting, i will have to searth some sites for COM with ASP and C#.
I thougt of the ugly way you mention about the C# vode poll a file or table, but it dont simes right to use.

It is coded by hand and we are only using our own code, or what do you mean?

I meant, are you starting a new ASP site ( if so, I can't imagine why ), or have you inherited one.

You obviously know C#, I don't see where the problem lies. The worst you could do is write an ASP.NET site that could be improved upon later.

You don't spin up COM objects now in your ASP project ? How do you handle the middle tier development ?

No, it would be plain terrible

We are building a Forum with ASP(not about ASP), to this forum we are building a Server/Client.
This Server/Client program will offer notification when someone is applaying to i thread that the user have subscibed to or somthing like that. The server will get the info that the client requests form the ASP Forum page(or how we now whould have to sulve the problem).
This way users will get posibility to answare on threads and PM with out going to the FORUM page.
This project is a School project
We dont use COM and have never done, but it would be intressting to learn, if its the way to go(only way maby? besides the ugly one)

OK - well, I strongly recommend you don't do this, but use ASP.NET instead.
Reasons - first and foremost, asp sucks. Secondly, you're learning or know C# already, and COM means C++. You cannot do a meaningful ASP site without a middle tier, which means you need to write a COM component. This is a hell of a pain if you don't already know COM and C++.

COM is required to do anything half decent in ASP, assuming you want to do it properly. ASP.NET is definately the way to go here. Who suggested asp, your teacher ?

We can C++ good, and if there is no other way we will have to make the COM component one way or the other.
Ther ASP forum is on good way to finish as well ass the Server/Client.
Yes we was about to gå with ASP.NET but our teacher dident agree, it was harder for him to check our project.
He also whanted us to use Access insted of SQL becourse its easyer for him to check.

OK, so your core problem is that your teacher is a moron. I suggest finding another course, or at least not putting too much faith in this one.
The only decent way to do ASP development is to put the business logic in a C++/COM component and then call it from the asp, that way you can limit the ugly VBscript code to next to nothingness. There are plenty of articles around on COM development, but it's a bit of a mind melt at first, at least it was for me.

Okay, i understand.
Thanks alot for all help, maby we do the ugly way after al, if we not are going to use this forum for real anyway.
And build a forum in ASP.net later on.

I've got to agree with Christian. This is a really bizare way to design an application.
Another option for getting the ASP application to comunicate with the server is through a WebService interface rather then a COM interface. That way you would at least learn something about ASP.Net and use something that in it's early stages of adoption, rather then on it's last legs like COM.
I can imagine the sinking feeling one would have after ordering my book,
only to find a laughably ridiculous theory with demented logic once the book arrives - Mark McCutcheon

Okay! thanks alot, we will look in to Webservices, wh have thougt of that before but we dident know that is suported ASP to.

the subject says it all, how do I create an event handler for when a the active tab in the tab control is changed?
|
|
|
|
|
Select your TabControl in the Form Designer, go to the properties window, select the events view by clicking on the yellow bolt and finally double click on the entry TabIndexChanged.
Visual Studio will then create the following code for you. Of course you can code this by yourself too.
this.tabControl1.TabIndexChanged += new EventHandler(tabControl1_TabIndexChanged);
private void tabControl1_TabIndexChanged(object sender, EventArgs e)
{
}

In the documentation on this method it says i can extract the read data within the callback method? i dont understand how to do this...
eg
NetworkStream str = (NetworkStream) result.AsyncState;
byte[] myReadBuffer = new byte[2048];
int numberOfBytesRead = 0;
numberOfBytesRead = str.EndRead(result);
it says "To obtain the received data, call the AsyncState method of the IAsyncResult, and extract the buffer contained in the resulting state object"
so in my case the IAsyncResult = result and I case the stream state from it but how do i get the data? as theres no method to call??
confused

Create a object which looks something like this
class ObjectState
{
public byte[] myReadBuffer = new byte[2048];
public NetworkStream str = set the network stream object u had created
}
now when you call beginread call it this way
ObjectState state = new ObjectState();
networkstream.BeginRead(state.myReadBuffer, 0, 2048, AsyncCallback method pointer, state)
//Pass state object to last parameter of BeginRead.
when u endread
ObjectState state;
state = (objectState) result.AsyncState;
int numberOfBytesRead = 0;
numberOfBytesRead = str.EndRead(result);
now use state.myReadBuffer; //This should contain the data u r looking for

Say I have this:
class Boo
{
private int x;
private Foo f;
public Boo()
{
x = 0;
Foo = null;
}
}
Can I use the Wizard to inplement the constructor? Keeps telling me NO. -thanks...

Well, in those particular cases, they will be initialized to 0 and null by default.

So it's answered your question, but you feel the need to ask here ?
What wizard ? You've implimented a constructor as far as I can see, what do you mean ?

Hey
I'm doing a little C# exercise and it involves overriding an inherited method
Here is my code
using System;<br />
<br />
namespace BookOverride<br />
{<br />
class Book<br />
{<br />
public string Title()<br />
{<br />
return "Damn Good Book";<br />
}<br />
public string Rating()<br />
{<br />
return "5 Stars";<br />
}<br />
}<br />
<br />
class OtherBook : Book<br />
{<br />
public string Title()<br />
{<br />
return "Some Other Damn Good Book";<br />
}<br />
}<br />
<br />
class Class1<br />
{<br />
static void Main(string[] args)<br />
{<br />
Book bc = new Book();<br />
Console.WriteLine(bc.Title());<br />
Console.WriteLine(bc.Rating());<br />
<br />
OtherBook ob = new OtherBook();<br />
Console.WriteLine(ob.Title());<br />
Console.WriteLine(ob.Rating());<br />
}<br />
}<br />
<br />
}
Now the funny thing is that my VS .NET tells me that new is required when creating the method in class OtherBook, but the whole thing works without it? I do get a warning though
warning CS0108: The keyword new is required on 'Polymorphism.B.Foo()' because it hides inherited member 'Polymorphism.A.Foo()'
Anybody knows why it issues a warning instead of an error?
I am gonna use the new keyword from now on. It's nice to see which methods that get overridden, but does it have a valid purpose other than that?
