I created a dll, and need support licensing.
now, i import IClassFactory2 interface,see:
http://www.pinvoke.net/default.aspx/Interfaces/IClassFactory2.html[^]
then use it in class:
public class HelloWorld: System.Windows.Forms.Control,IClassFactory2
please, how to realize this IClassFactory2?
and should i call procedure in HelloWorld create procedure?

It's a COM interface, not an interface in the sense of anything .NET. Using it, seems utterly insane to me. I get the feeling you googled 'C# license' and found this, but have no idea what it is. It's not going to create licensing code for you, I don't see any way that it helps you at all.
Don't forget that anyone can read your dll's source code with reflector, whatever licensing you decide to write.

IClassFactory2 is not like a .NET interface. To use it, you need to use the COM subsystem to get a reference to the class object present inside your COM object. The sample at the bottom of the page you linked to provides a bit more detail, but I would suggest that you need to read up on COM before you proceed any further.
As a side note - .NET assemblies (unless marked as COM objects) do not contain this interface.

Hi to all,
I want to create multiple documents or reports (Word Files or PDF Files) as following format,
Reference No:
Name:
----------- -------------- ---------------
Surname First Name Middle Name
Date Of Birth:
I have to fill the content in blan spaces.
How I can do above formmating while generating files?
In one forum, it is written to use StreamReader & StreamWriter classes to create formatted files.
How to use StreamWriter using content of a StreamReader (from a fixed file), to generate new formatted file?
Regards,

You can create an rtf file that ms word can read by doing the following:
string line;
using (StreamWriter writer = File.CreateText(@"C:\file.rtf"))
{
line = String.Format("Reference No: {0}", 3233);
writer.WriteLine(line);
writer.WriteLine();
line = String.Format("Name: {0}", "Ron");
writer.WriteLine(line);
writer.WriteLine();
//....
writer.Flush();
}

Thanks for suggestion.
With the help of your code, I have wriiten statements as follows,
line = String.Format("Name: {0} {1} {2}", txtLastName.Text, txtMiddleName.Text, txtFirstName.Text);<br />
writer.WriteLine(line);<br />
writer.WriteLine();<br />
line = String.Format("Date OF Birth: {0}", dtDateOfBirth.Value.ToString("dd-MMM-yyyy"));<br />
writer.WriteLine(line);<br />
writer.WriteLine();<br />
line = String.Format("Address: {0}", txtAddress.Text);<br />
writer.WriteLine(line);<br />
writer.WriteLine();<br />
writer.WriteLine();<br />
line = String.Format("Education: {0}", txtEducation.Text);<br />
writer.WriteLine(line);<br />
writer.WriteLine();<br />
writer.Flush();
Output file is as,
Name: ASD FGH JKL
Date OF Birth: 30-Feb-2009
Address: Block Number,
Area, City
PinCode
Education: Done School in 1999, with % of Marks.
Done PG in 2004 with % of marsk.</
But I want output file as with 'Justify' alignement,
Name: ASD FGH JKL
Date OF Birth: 30-Feb-2009
Address:
Block Number,
Area, City
PinCode
Education:
Done School in 1999, with % of Marks.
Done PG in 2004 with % of marsk.
How to do this?
Thanks & Regards,

I am not too familiar with rtf yet I can suggest an alternative (less elegant) solution: You simply add a tab char to your output string:
line = String.Format("Address:");
writer.WriteLine(line);
line = String.Format("\t{0}", txtAddress1.Text);
writer.WriteLine(line);
line = String.Format("\t{0}", txtAddress2.Text);
writer.WriteLine(line);

Thanks for the suggestion.
I tried it. But it is not going to work properly with a Paragraph (from multiple lines textbox).
Is there any formatting function availables with StreamWriter?
Else do you know how to use macro ( written by Microsoft Word in VB ) in C#?
Thanks & Regards,

I do not have much input on both of your questions.
AS far as I know, formatting is done with string.Format and StringBuilder.AppendFormat which formatting wise is the same thing. I can suggest that you check what kind of char to inject to your string (like a paragraph mark) in rtf.
I have no experience using office marcos from code. You can look at MS Office Dev Tools or if you are using VS 2008 try an Office add in project.
You can also try reposting your question and give the options you are trying (rtf, macro etc.)
I am interested in hearing the solution you find.
I hope this helps

I will do that.
Now I am using StreamWriter to create a rtf file as per your suggestion.
I have 2 questions,
1. Can I add image using StreamWriter? & How?
2. If now possible to add image using StreamWriter. Can I creat/append a file using existing file which is having some data (for example image)?
I tried to add image using StreamWriter, but didn't get any solution.
Thanks & Regards,

Thank you.
I think it is be helpful for me. Provided class has AddImage method too.
I will reply to you, as soon as I complete my task.

Thank you very much.
It is very helpful for me, to generate a file with formatted text & image.

Dear All,
I have created a very basic and simple windows service application using c# in vs 2005.
i have override the "onstart" method and i want that when my service starts a message should appear just to confirm that service starts running.
the service starts successfully but no message appears to me. i have tried to write that message to a file but still no file is created.
this the code bellow
protected override void OnStart(string[] args)
{
System.Windows.Forms.MessageBox.Show("Service is start...");
}
i have googled and used topic in msdn to create window service application.
why the message box does not appear when i am starting the service?

Services do not show UI. They are logged in as adifferent user and can not display data to a desktop. You can use Trace.Assert(false,"Hello");

yeah you are right, but if we enable the option "Allow User to Interact with Desktop".
we can show UI to the user.
i have enabled this option through code, still i need to restart my computer to get affected. I want this without restarting the system.

Instead you can use a client application that interacts with the service.
Using GUI in services is dangerous

can you please have more detail on client application and the interaction way between client and server application.
you mean i should call window forms from my installer class.
|
|
|
|

This is a suggestion of implementation.
The installer should install both service and application. The service should run independently (treated as a server) and the application should run as a client, post requests and run the service to do what it needs to. The connection between the client application can be implemented using .net remoting and the interaction will be transparent. My preferred way is to implement a service and a client application that runs from the system tray using a notify icon. The client application can have the service controller for starting/stopping/pausing/installing/uninstalling the service.
I saw some articles around the code project with samples of notify icons, service controllers and .net remoting. I hope this helps

This is VERY bad practice. I believe you can't even do this in Vista.

You can't display interface components in a Windows service.

You can - you shouldn't, but you can. Windows Services have a property "Interact with desktop" that allows a user to do precisely this - it's yet another crappy design decision.

I know, but I was trying to keep it as simple as possible for the guy.
