reference type in EXE?

George_George25-Apr-08 22:08

25-Apr-08 22:08

Hello everyone,

We can refer and use another type in a C# DLL file, but can we refer and use another type in a C# EXE file (build as executable)?

thanks in advance,
George

I don't know if you can create a reference to an exe, did you try ?

I'd be inclined to factor the types needed by two exes out into a dll, in fact, that is exactly what I have done in the past.

Hi Christian,

What means "I'd be inclined to factor the types needed by two exes out into a dll"? Could you say in other words please? My English is not very good. Smile | :)

George

Exe 1 contains a class 'Fish'. You want exe 2 to use the Fish class. That's your question, right ?

I'd create fish.dll, which contains the fish class. Then, I'd reference that dll in BOTH my exes, in other words, the bits in exe 1 that you want to use in exe 2, I'd move to a dll and use that dll in both exes.

Thanks Christian,

Yes, this is my case. In my situation, it is previously designed as an EXE. I am wondering whether I can refer the types in EXE directly without rebuild and redeploy as DLL. Smile | :)

I am not sure, but I guess using reflection you can invoke methods from assemblies(dll/exe). Here is an article[^] talks about reflection. Hope it will help.

All C# applications should call Application.Quit(); in the beginning to avoid any .NET problems.- Unclyclopedia

Thanks N a v a n e e t h,

What I mean is to add reference to types in EXE during compile time (just like what we did for a DLL assembly), I think reflection is using types in another EXE during runtime, right?

----------------------------------------------------
my problem is this

in textbox2 need to display "central proccesing unit"

how to do please help

Christian Graus25-Apr-08 20:28

Buy a book on SQL and one on ADO.NET. This is really basic stuff.

Select FULLFORM from <insert table="" name="" here=""> where SHORT = 'CPU'

Write a stored proc for this or parameterise your query. NEVER build SQL with the raw input of text boxes.

I stupidly put a note to insert the table name, inside <> and forgot to escape them. I didn't see the table name in his original post.

Derek Bartram26-Apr-08 11:50

Easily done, we've all done it a million times. I wasn't picking you up on your code, just didn't want the orriginal poster to get confused when it didn't work. I've always found SQL errors particularily unhelpful; and SQL Server 2008 management studio hasn't improved that at all (although the intellisence is nice).

Hello Everyone.

I am currently having a lot of trouble with .NET sockets.

I am trying to create a client with a windows forms interface. I have attempted to create a communication class which basically contains some functions for connecting and managing the connection.

public class connection {<br />
<br />
private TCPClient _client = new TCPClient();<br />
<br />
public bool Connect(string hostname, int port) {<br />
   try {<br />
        _client.Connect(hostname, port);<br />
        return true;<br />
   } catch {<br />
   return false;<br />
   }<br />
}<br />
<br />
public bool IsConnected() {<br />
   try {<br />
        if (_client.Connected) {<br />
        return true;<br />
        } else {<br />
        return false;<br />
        }<br />
   } catch {<br />
   return false;<br />
   }<br />
}<br />
<br />
}<br />
<br />

Is a really basic connection class. I have multiple forms which I would like them to be able to control the connection and receive and display information on them.
I understand that the usual way for all form instances to access the same things, is to declare those things as static. I have tried to make this class a static class but the TCPClient throws an error telling me that you can't have a static instance. I don't want multiple instances of this class. The client only needs to handle one connection at a time.

I have gone through all C# tutorials and articles on code project, and they are really helpful if you are only using one form (with delegates) and custom event handlers. I want to be able to receive information from the socket, deserialize the data and use that data to populate classes, and form controls (for example: list box - of connected clients.)

I would really appreciate it if you could explain why I can't have a static instance and maybe possibly links to tutorials or code samples of something similar to what I am describing above so I can try to understand how it works.

Kindest Regards,

Mike

change font colour in richtextbox using timer.

26-Apr-08 7:42

It sounds a little suspect the way you are trying to do it.... but the way to do what you are trying is;

public abstract class connection {
     private static TCPClient _client = new TCPClient();

     public static void Connect(String hostname, int port) {
          try {
               _client.Connect(hostname, port);
               return true;
          }
          catch (Exception e) {
               return false;
          }
     }

     public static bool IsConnected {
          get {
               return _client.Connected;
          }
     }
}

You would the access via;

connection.Connect("192.168.0.1", "50");
Console.WriteLine("Is it connected? " + connection.IsConnected.ToString());

Someone else would be better able to answer this, but this seams very insecure and there is no protection of the TCPClient which potentially is sending user data?

Hi!
One way is to first set the RTB's selection, assign the color you want to your RTB's SelectionColor and reset the selection afterwards.
Try this and if you have further problems, ask again (probably posting some code).

Im not sure you will be able to, after a program loads a file, it's usually stored in memory until the user saves it. Each application will probably have some variable somewhere which stores the location of the file (so when you click save it knows where to stick the data) but i don't think you'll be able to access it.

Could you clarify the question, I don't really understand what you are trying to do.

System.Environment.CurrentDirectory

and

System.Reflection.Runtime.Process

would both be worth a look though I think.
