I am developing a C# application and I want to know how can I protect the computer from being used> i think all software are not strong including the activation method which Microsoft uses that's why I want to know if it's possible to use a hardware protection like USB dongles with my .NET application?

you have to buy the dongle kit

Yes, in fact many of the "dongle" vendors have API's you can use. However, keep in mind that it is very easy to reverse engineer .NET applications. Your time is better spent on a good business model than protecting your software from intentional, dedicated piracy.
One thing I have been considering, lately, is the concept of custom builds for clients using encryption based on their details. Then it would be much easier to catch a pirate. I haven't worked out all of the details yet, however.

Hi,
linking a license to some hardware characteristics has some drawbacks; what if the customer for good reasons wants to change the motherboard, the disk, the CPU, the amount of RAM, or anything else. He would like to be sure that won't affect the availability of his licensed software.
Also some internal "unique IDs" can be faked (MAC address) or are unreachable (CPU uniqueID).
I am in favor of adding a specific piece of hardware; the cheapest that holds a unique ID currently is a USB memory stick (I haven't found one yet without a very long ID; AFAIK there is no guarantee that they all will be different, but there will be a great many different values for sure); the nice thing is USB sticks is something your customer may already have or can buy himself.
What remains a problem is the reverse engineering being rather easy on .NET

The USB dongle solution is actually more complex and complete than Unique ID, you can load secure software and private keys onto them. Check out Aladdin eTokens for an example.

Sure, it is also more expensive and requires more effort to set it up. IMO it would not fit well protecting a 10 to 50$ app.

It makes no sense to secure a 10 to 50 dollar app. beyond keep them honest policies.

It makes little sense to buy a 10 to 50 dollar app. 
But seriously, that sounds more like it should be on the honor system -- "If you like this software, please consider sending me $10 (or more!) to encourage future development."
That way, the users become the distribution medium, and there is no "piracy".

Hi,
vs2005 .net2
I have a win form app running on a number of different clients. The clients use a web service to communicate with a database.
When a client loads it instanciates a web service object and the web service instanciates its own log object which writes to a log file on the server specific to that client.
So if 50 clients are running I want 50 web service instances running.
Ive noticed that different clients write to different log files...
When 2 clients load and instanciate a web service - are 2 or 1 web service instances created on the server?
Can I ensure that a client only uses the web service that it instanciates?
Thanks in advance...

I think that's what is Happening.
A Client can use only the Web Service that it instantiates in your case

Ok The problem is as follows:
Lets say Client A starts, it instanciates a web service that is configured to write to log file A on the server.
Then say Client B starts, it instanciates a web service that is configured to write to log file B on the server.
The problem is now when I call a web method on Client A it writes to log file B on the server.
So it appears that all clients will write to the file determined by the last instanciated web service. - This is not the way I thought it worked...
However to get around this issue I could modify the log methods to take a parameter (being the log file path) every time it writes...

I thought it was only one, but I'm certainly no expert.
I hope an expert can clear this up for both of us.

Can you maybe show what you tried? Converting it to plain text didn't work? Why not go pdf->plaintext->doc
shouldn't be that hard
|

I am getting the plain text out of a pdf
but not the images and also the formatting of
the characters are not gettable....
Thanks

Unless you give more details about what you intend to use this information for, I hope that you will get no replies.

Why do you hope that? It's a fair question most probably posted by someone who works within Financial Services IT who needs to do this for their job.

The bank or security agency you work for will have this information. You don't need it for any other reason.

Isn't that a protocol and not a format?

I am new to Microsoft Report Viewer and trying to a use for the first time. I have just created a blank report in Visual Studio and added a textbox with the valie:
=Fields!vehicle_chassis_number.Value
In Visual Studio, hee is my Code:
data_set = new DataSet();
reportViewer1.ProcessingMode = ProcessingMode.Local;
LocalReport rep = reportViewer1.LocalReport;
rep.ReportPath = @"C:\Users\Jassim\Documents\Visual Studio 2008\Projects\Taajeer\Taajeer\Report1.rdlc";
sql_connection = new SqlConnection("Data Source=.\\SQLEXPRESS;initial catalog=rent_a_car_company;integrated security=true");
sql_connection.Open();
sql_command = new SqlCommand("sp_get_agreement_by_id", sql_connection);
sql_command.CommandType = CommandType.StoredProcedure;
sql_command.Parameters.Add("@vehicle_id", SqlDbType.Int).Value = 1;
sql_adapter = new SqlDataAdapter(sql_command);
sql_adapter.Fill(data_set);
sql_adapter.Dispose();
// sql_connection.Close();
ReportDataSource dsReport = new ReportDataSource();
dsReport.Name = "Invoice_sprocInvoiceView";
dsReport.Value = data_set.Tables["Invoice"];
rep.DataSources.Add(dsReport);
reportViewer1.LocalReport.DataSources.Clear();
reportViewer1.LocalReport.DataSources.Add(dsReport);
reportViewer1.RefreshReport();
rep.Refresh();
this.reportViewer1.RefreshReport();
but I am getting this error message:
Error 1 The Value expression for the textbox ‘textbox3’ refers to the field ‘vehicle_chassis_number’. Report item expressions can only refer to fields within the current data set scope or, if inside an aggregate, the specified data set scope.
