What have you tried so far?
Post some code and explain where you think it is failing.

i tried Dot Fuscator from command prompt to encrypt the assembly.

The sample code for dotfuscator :
i am using c++ code to generate dll from c# class.

CString pathDot="C:\\Program Files\\Microsoft Visual Studio 9.0\\Application\\PreEmptive Solutions\\Dotfuscator Community Edition";
sprintf(command,"\"%s\\dotfuscator\" /in:c:\\IS500Licence\\Licence.dll /v",pathDot.GetBuffer(0));
system(command);

Remoting server in Window Service

Hi All,

I have created a simple remoting server inside a Window Service as :

<pre>TcpChannel tcpChannel = new TcpChannel(8085);
                  ChannelServices.RegisterChannel(tcpChannel,true);
                  WellKnownServiceTypeEntry entry = new WellKnownServiceTypeEntry("RemotingWindowSrvc", "RemotingWindowSrvc.MailFormat", "MailFormat", WellKnownObjectMode.SingleCall);
                  RemotingConfiguration.RegisterWellKnownServiceType(entry);</pre>

Then we try and make call to this server in my client as:

<pre>private void GetRemoteObject()
            {
                  TcpChannel chan = new TcpChannel();
                  ChannelServices.RegisterChannel(chan);

                  MailFormat obj = (MailFormat)Activator.GetObject(typeof(MailFormat), "tcp://localhost:8085/MailFormat");

                  obj.sendUserRegistration("...");
            }
      }</pre>

MailFormat: is the name of the Class, being called here.

But upon calling "obj.sendUserRegistration("...");", client hangs indefinitely.

please help me with this.

Thanks,

Puneet

Hi,

Thanks a lot for the reply, I have been able to solve this problem.

It was hanging cause, it wasn't able to resolve the function name. But once I signed the assembly and deployed it in GAC, it was able to recognize it and call the function.

I am putting the code for your reference:

Dim ch As TcpChannel = New TcpChannel(8085)
ChannelServices.RegisterChannel(ch)
RemotingConfiguration.RegisterWellKnownServiceType( _
GetType(TrialClassLib.MailFormat), "myRemoteObject", WellKnownObjectMode.Singleton)

DateTime now = DateTime.Now;
string date = now.ToString("dd.MM.yyyy");
string time = now.ToString("HH:mm:ss");

// put date in textBoxDate.Text
// put time in textBoxTime.Text

please try this one

textBox1.Text = System.DateTime.Now.ToShortDateString();

textBox2.Text = Regex.Replace(System.DateTime.Now.TimeOfDay.ToString(), @"(.*?)\.(.*)", "$1");

textBox3.Text = System.DateTime.Now.DayOfWeek.ToString();

Not saying this is wrong (although a regex is a little heavy and unreadable for a simple task like this), but it is a good idea to use

DateTime dateNow = DateTime.Now;

and then to work with "dateNow", rather than use "DateTime.Now" three separate times. The reason being that each time you use .Now it returns the current date and time - which could potentially be in a different hour, day, year, or even century. If you habitually use just the single time reference, then you remove a source of potential bugs in future code.

DateTime dtime_Now = new DateTime();
string str_Day = dtime_Now.Date.ToString();// The 'day' value
string str_Time = dtime_Now.TimeOfDay.ToString();// The 'time' value

TextBox tb_1 = new TextBox();
tb_1.Text = str_Day;
TextBox tb_2 = new TextBox();
tb_2.Text = str_Time;

Surely that should be

DateTime dtime_Now = new DateTime();
DateTime dtime_Now = DateTime.Now;
string str_Day = dtime_Now.Date.ToString();// The 'day' value
string str_Time = dtime_Now.TimeOfDay.ToString();// The 'time' value

TextBox tb_1 = new TextBox();
tb_1.Text = str_Day;
TextBox tb_2 = new TextBox();
tb_2.Text = str_Time;

What you have posted gives a date of 01/01/1901, or whatever the default date is.
