Hi everyone
I want to get printer information using “Printer job description language “in c#.
My question is:

I have installed “HP LaserJet 1300” printer which is running on “DOT4_001” port. Now I want to send PJL command to this printer and want to get information about printer.

I have a Following Interface.
public interface IToString
{
string MyString();
}
I have Implement that interface in the following class
public class Implementor : IToString
{
#region IToString Members
public string MyString()
{
return "Siva";
}
#endregion
}
In Another class i am calling the interface method Mystring()
My Question is..
Using the object instance we can directly call the method MyString
Like ..
Implementor dd = new Implementor();
MessageBox.Show(dd.MyString());
But Why we use interface instance and we call that method..
Like..
IToString Reference1 = new Implementor();
MessageBox.Show(Reference1.MyString());
What is advantage using interface here?
public partial class Form1 : Form
{
private void button1_Click(object sender, EventArgs e)
{
IToString Reference1 = new Implementor();
MessageBox.Show(Reference1.MyString());
Implementor dd = new Implementor();
MessageBox.Show(dd.MyString());
}

None, until you have a completely unrelated class, which you want to share the common interface. You can't have one reference point to two totally different classes, but you can have a reference to the part of those classes that is defined by the common interface.

Hi
Is it possible to get the current function or property name using reflection? If it is then how?
Regards
Shajeel
|
|
|
|
|
string name = System.Reflection.MethodBase.GetCurrentMethod ().Name;
|
|
|
|
|
any thing similar for property?
Regards
Shajeel

Its the same..
Properties are methods in IL code.
However , you will have to remove "set_" and "get_" prefixes that are applied to property methods.
eg if you have a property called "Foo" and you use the code I supplied in the "setter"
you will get "set_Foo"
and in the getter you will get "get_Foo"

I need to find all of the unused public members in my solution.
I have found one tool - NDepend - that will do this.
I am currently evaluating Resharper and I cannot tell if Resharper has this functionality.
Does anyone here know if Resharper can be used to find unused public members? If so then how?

The IDE does that for you, no need to buy anything. Just check your warnings

No - I think the VS IDE only finds unused private members.
You should be able to set up a simple example in your dev environment to validate that the VS IDE does not identiry unused public members.
Even 3rd party tools like FXCop only find unused private members.
The only tool that I've found that finds unused public members is NDepend through the use of CQL.
If you can show me a test case where VS identifies unused public members then please post it here.

Just because it's unused today doesn't mean it will be unused tomorrow.

No. It would be impossible to tell for sure - the member might be used in a different solution.
Things you make public/protected are generally things you have to support. I'd be mighty annoyed if MS started dropping public members from stuff I use because they don't use it in house

I am attempting to create an application which hooks input and output of a console application (usually cmd.exe) running in a Process object, and render the output in a custom fashion. So far it works great (Check out http://tom.net.nz/consolewrapper/ if you're curious  ) but difficulties are arising with passing through commonly used console keystrokes, such as TAB or Ctrl-C. The streams happily handle basic strings of course, but don't like advanced keys so much.
The Process is started as such:
<br />
_process = new Process();<br />
_process.StartInfo.FileName = appName;<br />
_process.StartInfo.UseShellExecute = false;<br />
_process.StartInfo.RedirectStandardError = true;<br />
_process.StartInfo.RedirectStandardInput = true;<br />
_process.StartInfo.RedirectStandardOutput = true;<br />
_process.StartInfo.CreateNoWindow = true;<br />
<br />
_process.Start();<br />
<br />
_stderr = _process.StandardError;<br />
_stdout = _process.StandardOutput;<br />
_stdin = _process.StandardInput;
I have tried using SendKeys, but since the process has no window, it seems to send the keys directly back to my interface, causing a rather nasty feedback loop. There also seems to be no dice on passing keystrokes to a Stream.
I would really hate to have to re-invent the wheel on TAB completion etc! Any help or ideas appreciated!

I have created a class file and added a boolean value that's accessible for ALL the methods. The boolean is set to "bool IsLoggedIn;" when I execute the login method everything is fine and the bool gets set to true. when I execute method 2 the boolean is back to false!!
How can i retain the value in the boolean and use it over more than one method in that class?
Thanks!

Unless your setting the thing back to false, then i don't know whats going on. You do have something like this right:
class MyClass
{
private bool IsLoggedIn = false;
void Login()
{
IsLoggedIn = true;
}
...
}
My current favourite word is: I'm starting to run out of fav. words!

As a test, try making the variable, IsLoggedIn static (static bool IsLoggedIn).
If it retains the value now, you are somehow creating multiple instance of that class. Each time you re-create that class, the value of IsLoggedIn will be initialized as false.
Did that make a difference?

it's often better to use delegates than globals. But, as others have said, static is your problem here.

We'd probably need to see the code.

Is this an ASP.Net app by any chance?
If so you need to read about the page lifecycle, as your class instance is different for every request.
