I need help in remoting. Im doing this proyect, I already have the client server connection and everything. But what Im missing is that I need for the server to access the object that, the server, makes for the client.
Let me explain. The server makes the object to be remote. The client gets a refrence of that object. The clients makes all the data in the refrences. What I need is that the server can access that object so I can get the data from the client and send it to the database.
Please I need help from someone as soon as posible.
Thanks..!

I have a service that uses a dedicated port #. This service can be installed in one or more computers on the subnet. Anybody knows of a simple code that allows me to detect the port # and how many are running (same subnet or accros the router will be fine)
Any help will be greatly appreciated

You don't know the port on which the app is running?

The port number is constant, it does not change.

If you have recorded its physical path, then I think you may format the string and copy the text that is \, and then you can display the text as its name.

Ok here is a summary of what the program is doing.
Am calling a child process called Helloworld from a parent process builder using the command line
> Builder.exe c:/helloworld.exe c:/log.txt
Before i capture the output on the helloworld from the builder(before i used the UseShellExecute and RedirectStandardOutput, it used to show both processes on the screen.
but after i capture the output on the helloworld from the builder, it no longer shows the child process (helloworld)
here is the code snippet
anyone has an idea why it does not show it, and if yes, how should i do it.
...
....
p = new Process();
p.StartInfo.FileName = targetFile;
p.StartInfo.CreateNoWindow = false;
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.UseShellExecute = false;
p.StartInfo.WindowStyle = ProcessWindowStyle.Normal;
p.Start();
pStartTime = (p.StartTime.ToString());
processOutput = p.StandardOutput.ReadToEnd();
p.WaitForExit();
pEndTime = (p.ExitTime.ToString());
p.Close();
...
...
PLEASE HELP !!
Thanks

Hello,
I created a database in Access and then protected it (Tools->Securityy->Set Database Password).
After that, I created a new WinForm C# application and in the designer I dragged an OleDbConnection to the form, set the connection string to use the previously created database and to use the password (I used Jet 4.0 OleDbProvider).
All well, but when I hit "Test Connection" I receive this:
"Test connection failed because of an error in intializing provider.
Cannot start your application. The workgroup information file is missing
or opened exclusively by another user."
Access is closed...no one is using the file.
Any help is appreciated.
Thanks

Me again...I forgot to mention that I can connect to the database from source code with this connection string:
ConnectionString="Provider=Microsoft.Jet.OLEDB.4.0; Data Source="+AppPath+"; Jet OLEDB:Database Password=abc";
Is this a bug in .NET IDE?
Regards

Hi!
What's the value of AppPath? This should be the full path to the mdb-file, but if it's really only your application's path that'll be a problem...

Hi,
Yes, it is the full path to .mdb file.
I dont have any problems connecting to the database from source code (this works OK)...the problem is I can't do it from the designer (when you set the properties of the connection string of a OleDbConnection and when you press the "Test Connection" button).
Thanks

MessageBox.Show("Hello world");
MessageBox.Show("Welcome to C#");
Of course, you need to import the System.Windows dll and be using System.Windows.Forms.

Many Many Thanks, I really appreciate that. So, its the same syntax that we use in C++.
Thanks

No, in C++, they are global API calls, MessageBox or AfxMessageBox. Here, there is nothing global, so everything that would be global is now a static method on a class. MessageBox is a class, and it has one static method, called Show.
But yeah, the net result is the same

ok....I got it.Thanks
So, we don't declare anything globally but we use a static method on a class....
Thanks again

Yes, we CAN'T declare true globals, because C++ allows OO, C# enforces it. So, a static member is the obvious way around that.

I have been offered a job writing an image viewer for a web app. Now, I'm not sure yet, but I suspect they will want to be able to click a link in their web app, and have an image viewer come up on the client. Can I do this in C# ( set it up so that when I click a link, my app gets installed if need be, and then run using the image from the web, even though it's not associated with this image type ) ?

Hi,
I am writting an application in C#.NET.This application will run daily once.
The application has to fetch the data from DB2. The volume may be 15 million records(each record will be having 120 fields). I will be processing that data and the resultent data will be sent to DB2(diff table). Will ".Net"(dataset) can handle that much volume of data?
Suppose the data is in some flat file(in some machine) is file handling functions are best way to use.
Please Suggest the best possible solution.

The best possible solution, assuming you catch batch the data, is to use the ADO.NET stuff that's designed to talk to databases. Flat files on the machine are a terrible idea.
If it was me, I'd write the code to create a similar dataset, and stuff it with 20 million dummy records, to see what it does. However, if it was me, I'd never grab that many records anyhow, I'd make all operations on the data happen in the database, and my app would never retrieve more data than it needed to display on one page.

HI Christian Graus,
Thanks for the info,
Here I had to get all that data. I am not displaying any data in my application(just for testing i am using datagrids)..I just have to process it and put the resultent data in DB2.
Thanks and Regards,

Why do you need to process it all at once ? What's the process, that you can't do it within the database ?

15 million records might be a lot of records to process at once, its hard to tell without seeing the overall picture(there might be other compelling solutions). Even before looking for specific tech to use, see if you can do the processing in piecemeal and save the result and use it to work with the next batch. Though I think the previous suggestion of doing the processing on the DB side might be an issue if other apps are using it at the same time.
