You need to buy a book on C# and read it. It's pretty basic stuff that anything in quotes, is a verbatim string. Your variable name becomes a variable name only when it's not in quotes.
@"c:\code\" + filename + ".txt";

So you don't know how to use a variable instead of a literal string.
Here's an example:
This is some code with a literal string:
Console.WriteLine("Hello world!");
You can put the string in a variable and use that variable in place of the literal string:
string message;<br />
message = "Hello world!";<br />
Console.WriteLine(message);
This is very basic in programming, and what you are trying to do is on a much higher level. You should start with the basics before moving on to more complex things.

System.IO.FileInfo fi = new System.IO.FileInfo
(
string.Format
(
"{0:ddMMyyyy}_{1}_{2}.csv"
,
System.DateTime.Now
,
"hi"
,
123
)
) ;
using ( System.IO.FileStream tw = fi.OpenWrite() )
{
...
}
However, I do suggest you format the date as "yyyyMMdd" to comply with ISO 8601.
Don't bother testing for file existence unless you want to read it, not write it.
The OpenWrite will create the file if it doesn't exist, and overwrite it if it does.

Thanks for the info.;P
I was checking for file existance in case the file had already been created, so the new file should have some extra character in the name to differenciate them.

Well that's alright then.

System.IO.FileInfo fi ;
int seq = 0 ;
do

,
System.DateTime.Now
,
"hi"
,
++seq
)
) ;
} while ( fi.Exists ) ;
using ( System.IO.FileStream tw = fi.OpenWrite() )

I wrote a windows service that runs under the system account.
This service should launch other programs and monitor them, so it's a kind of a watchdog.
I use the System.diagnostics.process class to launch these programs.
The code is working perfectly when I run this in a simple console.
but this doesn't work in the service.
Process.start() simply returns, no program is launched, no exception is thrown...
what is wrong here ?
Is there another approuch that I can try?

The problem is you don't understand how services work. Services run under their own desktop, NOT the users desktop that you can see. The Process.Start() code worked. The application was launched. All you have to do is open TaskManager and click on the Processes tab to see that.
You have to configure your service to interact with the users desktop. Click Start/Run, then type SERVICES.MSC and hit enter. Find your service in the list and double-click it. Click on the LogOn tab and find the little check box that says something like "Allow server to interact with desktop" and enable it.
Now, YOU HAVE A MUCH BIGGER PROBLEM. Services run all the time, even when noone is logged into the machine. So, with no user desktop to show an app, you're service will still launch the applications, but noone will ever see them because there is no user desktop! Just logging into the machine will NOT automatically show you the launched applications either. They will be running, but on the services desktop only. There is no way to transfer the application between desktops. In order for the logged in user to see them, the applications would have to be killed and restarted.
Notice, in the .NET Framework's Service classes, that you don't get any "User logged on" events...

Before I used VC++, there is one command "Alt+F8" can realize the smart indent,
is there any similar command in VC#? I can not find it.
Please let me know if you knows. after all it is helpful!

In VS 2005, there's two commands, Format Selection (Ctrl+E, F) and Format Document (Ctrl+E, D), under the Edit/Advanced menu.
Not sure if that's what you're asking though....

There is no concept of user defined functions in .NET. SQL Server has user defined functions. What do you mean by this?
adilkazmi wrote: but when I migrated it to 2000
There's no such thing as VS.NET 2000. Again, what do you mean by this?

That's no such thing as VS.NET 2000. There's 2002, 2003, 2005, and soon to be 2008. Did you write an ASP.NET 2.0 application in VS 2005 and you're trying to migrate it back to an ASP.NET 1.1 app in VS.NET 2002 or 2003?? That's not going to work.

HI,
i've gor a form that act as a MDIparent
in that form there is another form - ChildForm

the FatherForm MenuStrip
i like it to expand but not to cover the FatherForm MenuStrip
any idea's?
THNKS 
have a great day

Did you set the MenuStrip's Dock property to Top in the MDIParent?? Calling it the "FatherForm" will probably confuse a few people.

Yeah, call it the MotherForm instead 
My current favourite word is: Waffle
Cheese is still good though.

HI,
yes it's by default
when i expand the ChildForm it's still cover the MenuStrip (not COvering so that it can not been seen but they get mixed togther, as now the ChildForm has The "ParentForm" Manustrip,
i'd like to expaned only just below the MenuStrip
Either way THNKS
and i will change from "Father" to "Parent" more accuret

This is the functionality of MDI forms. The menu of the MDIChild gets merged with the menu of the MDIParent. The form isn't hiding behind the menustrip. This is how it works if you maximum an MDIChild. No, you can't change it.

"Hashtable[]" is return object, I hope it return XmlAttribute object.
Which method need I to override?
|
|
|
|
|
You want to use the Dictionary class, which uses generics to specify type. Or if you know it's an XmlAttribute you can either derive from the Hashtable class and force the cast in there, or cast it yourself.

Hi friends![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)
How can I create a communication between two client that have invalid IP, with a server that has valid IP (like a mirror)?
|
|
|
|
|
If their IP is invalid, no-one can.
