The attributes under configuration properties/build/Outputs are output paths,XML documentation file, Generate Debuggin info, Register for com interop........There's no option for changing to a class library.

.net remoting with webForms clients which have to react of an event fired by the server

I have a big question for .Net Remoting pros:

I use a remote server which watch files and detect when modifications become. The server is a winForm. Then, I have Web clients which subscribe to the event "file modification" and have to do some work when the event fired.
- The remote configuration is ok because if I declare a simple function in the interface (link between server and clients), clients have access to this function and it work well.
- The problem is when the event fired, clients don't execute the code I put in the corresponding method in the WebForm. When I execute with the debug mode, I see that it enter well in the method and execute the code I put into but nothing happens. For exemple, I just test with displaying a message in a textbox when the event fired.
The webClients enter well in the receiveevent function, execute the corresponding code line, but there is nothing in the textbox.

I understood this is because it's the IIS which calls and react at the event and not the html page, the clients. In fact, if I tranform my web clients in WinForm clients, it works well: the code is really executed.

But I don't know what I have to do and I'm very tired and my brain too. Because I have searched on the Web for a week, 8 hours per day and I didn't find anything. There are all .Net remoting solution except this case: Web clients which subscribe to event fired by a server application. There are Web clients which communicate with a server but without event or WinForm clients with event.
So I really need some help, please... I will be very grateful about your help. Tell me if there are information lacks in my explication.

What on earth are you smoking?

You don't have to creat an object of anything... See my reply to the OP.

Easy. Make a public method on your parent MDI Form and call it from your children...

// Form1
public void StatusMessage(String message)
{
    // set your status bar message here.
}

// Child Form 1
this.MDIParent.StatusMessage(@"My status message goes here...");

Hi!

I have this herculian task of converting an asp.net web application written in classic asp style(Application Logic and Presentation in one .aspx file) to Code-Behind and UI style.

Any tips or strategies with regard to this dirty job are welcome Sniff | :^)

Best Wishes

You might want to ask this in the ASP.NET Forum.

But in my humble opinion - scrap it and rewrite the thing from scratch.

The ToolTip class doesn't support this. You can try this[^] article here on CP, but I don't know if it's going to help you. The code isn't documented or explained very well, as you can see by the articles rating.

Set the IDs of the checkboxes as you create them, or in databinding, or something.

Hi,

i'm trying to get my C# application to connect to a database which is located in another computer.

what are the steps required to make it function?

i have installed odbc .net data provider and i've tried using this connection string:

myConnectionString = "DRIVER={SQL Server};SERVER=localhost;UID=rfid; Trusted_connection=true;DATABASE=rfid;";

but it gives me a error of access denied or server doesn't exist, i'm not so clear about this, thus i hope to know what are all the steps required for both the client and server to do inorder to make this work

thanks!

Try changing your SERVER name from localhost to the actual name of the server machine. To get the machine name, right click on "My Computer" and select properties. Select the "Computer Name" tab and you will see the "Full Computer Name".

Hope this helps

i've tried connecting to a database in my own computer first, and this is my codes for the connection to test:

string myInsertQuery = "INSERT INTO test (id) Values(4)";

myConnectionString = "DRIVER={SQL Server};SERVER=localhost;UID=root; PWD=wq;Trusted_connection=true;DATABASE=rfid;";

OdbcConnection myConn = new OdbcConnection(myConnectionString);
OdbcCommand myOdbcCommand = new OdbcCommand(myInsertQuery);
myOdbcCommand.Connection = myConn;
myConn.Open();
myOdbcCommand.ExecuteNonQuery();
myConn.Close();

my userid is root, password is wq and database name is rfid, but still it gives me back a result of server doesn't exist or access is denied. is there anything wrong?
