A file is sent to print,and I want to store the content of that file in a notepad file. Means I want to maintain A print Record, that which file & content of that file is printed by the printer in separate notepad or any word document.
File contains only text data. Not images
how I do this. Any suggestions for doing this in C#.Net. please share some code so that I can understand.
Thanks in advance.

I would think you would need to hook into the printers API to get at the file. You might be able to monitor the network connection to the printer. Just some ideas, I would examine the business requirement very carefully it sound like a really great time waster!
Opening the file would depend on the file type, I would store the file in it's original format.

If you are not willing to use a book then you need to take lessons, we can't magic the knowledge into your head!

Then you need to study one of the languages that can create Windows applications. As this is the C# forum I suspect that may be your choice, so you could start by reading .NET Book Zero, by Charles Petzold[^].

Then you need to study web development, probably starting at the ASP.NET home page[^].
One of these days I'm going to think of a really clever signature.

first step:
analyzes your application
second step:
model a database
third step:
try to use n-layer model. is the best way for use a windows form / web form project
in internet there's a lot of examples how you can conect database, n - layer applications, consult youtube is the best for tutorial!!

How do you tell if an enum was passed as a parameter?
If it's not broken, fix it until it is
|
|
|
|
|
Why would you suppose that it wasn't?
|
|
|
|
|
I didn't just post some random question for the sake of posting.
I have a situation where I can call the method with or without the enum.
If it's not broken, fix it until it is

It usually helps to describe the problem, rather than posting a cryptic one-line summary.
Are you calling a method with an optional parameter? If so, any call which omits the optional parameter will automatically pass the declared default value:
void SomeMethod(SomeEnum theParameter = SomeEnum.Default) { ... }
SomeMethod();
If you're not using an optional parameter, you'll need to provide more information.

I posted "How do you tell IF an enum was passed as a parameter?"
Therefore, it should be clear that it is indeed an optional parameter. Not sure how that's "cryptic".
But yes, I want to be able call the method with or without the enum. Getting the default value doesn't help as there's still no way to kow if it was passed or not.

It may be obvious to you, but you wrote the question. Your question made no sense to me either.

Sorry, most of us wear foil hats to prevent the government from reading our minds. This has the unfortunate side-effect of blocking our own telepathic abilities. 
Your original question, "How do you tell if an enum was passed as a parameter?", might have been obvious to you, but judging by the responses you've received, it's not as obvious to other people as you might think. If you'd asked, "I have a method with an optional parameter; how can I tell whether or not the caller passed the parameter?", or included a small code snippet, we'd have had a better chance of understanding what you were asking.
To answer your question, there's no way to tell the difference between code which didn't pass the optional parameter and code which passed the default value for the optional parameter. The compiler generates exactly the same code for both.

I hadn't even considered it might be; I never user optional parameters.
Sounds like you want an overload instead. Come on, go olde school.

That's difficult to answer without knowing the signature of the method you are talking about.
if the sig is:
void MyMethod(MyEnum me) {}Then it is safe to say that me contains an enum value.
it it is:
void MyMethod(int i) {}Then it could be an enum, since they are integer values.
If you mean "Can I find out if an object was an enum?" then:
enum xx
{
v1, v2
}
void MyMethod(object o)
{
Console.WriteLine(o);
if (o is xx) Console.WriteLine("XX");
if (o is int) Console.WriteLine("INT");
}
void TryIt()
{
int i = 13;
xx x = xx.v2;
MyMethod(i);
MyMethod(x);
MyMethod((int)x);
}
Will print:
13
INT
v2
XX
1
INT

No, I'm not passing an int. I'm passing the actual enum value, as in
void MyMethod(bool var1, MyEnum theEnum)
{
}
then I want to either call it as
MyMethod(true);
or
MyMethod(true, MyEnum.TheValue);
So I want to determine of the enum was passed.
If it's not broken, fix it until it is

Depends on which version of .NET you are using.
.NET 4 introtuced Optional Parameters:
enum MyEnum
{
DefaultValue,
v1, v2
}
void TryIt()
{
MyMethod(true, MyEnum.v1);
MyMethod(false);
}
void MyMethod(bool var1, MyEnum theEnum = MyEnum.DefaultValue) { Console.WriteLine(theEnum); }
Before that, you could use params:
void MyMethod(bool var1, params MyEnum[] theEnum) { Console.WriteLine(theEnum); }
Which is a lot nastier.

Ya I'm in 3.5. So far I'm passing a bool to indicate if the enum was passed. Seems like there's no easy way.

You could set the parameter to params MyEnum[] enums:
enum MyEnum
{
DefaultValue,
v1, v2
}
void TryIt()
{
MyMethod(MyEnum.v1);
MyMethod();
}
void MyMethod(params MyEnum[] theEnum)
{
if (theEnum.Length == 1)
{
Console.WriteLine(theEnum[0]);
}
else if (theEnum.Length > 1)
{
throw new ArgumentException("Too many parameters");
}
}
But it is ugly and relies on run time checking which is dangerous at best.
Is there anything stopping you from just declaring two overloads?
void MyMethod() { }
void MyMethod(MyEnum theEnum) { }

OK, now we're getting somewhere!
Rather than passing a separate bool flag, you can use a nullable type[^] to pass your enum:
void SomeMethod(SomeEnum? theEnum)
{
if (theEnum.HasValue)
{
switch (theEnum.Value)
{
case SomeEnum.Item1:
{
...
}
}
}
else
{
}
}
SomeMethod(SomeEnum.Item1);
SomeMethod(null);

How silly. I don't see what all the confusion is about. Just do it the "standard" way.
enum eType
{
None = -1,
Enum1 = 0,
Enum2 = 1,
etc.
}
void SomeMethod()
{
SomeMethod(eType.None);
}
void SomeMethod(eType e)
{
}

According to MSDN[^]:
A procedure cannot detect at run time whether a given argument has been omitted or the calling code has explicitly supplied the default value
You have a few choices. You can overload the method and have a private one with a bool flag:
public void Method()
{
Method(true, 0);
}
public void Method(YourEnum yourEnum)
{
Method(false, yourEnum);
}
private void Method(bool ignoreEnum, YourEnum yourEnum)
{
if(ignoreEnum)
{
}
else
{
}
}
You can use nullable as suggested in an answer above.
You can add a value to the enum Invalid = -1 and use that as the default parameter value.

Hello,
I'm currently developing an Integration Package for VS 2010. When I'm debugging the project, it does normally start an experimental hive that includes my package.
My problem: Changes in *.vsct file does not have an effect on the loaded package [at the hive]. Changes in .cs files are accepted normally to the hive package after debug.
The way I found to fix this is to reinstall the package in the hive, but this is definitly no suitable solution.
Thanks for help.
