You're going to have to elaborate if you were hoping for any kind of useful answer.

You are going to have to target the reader with an SDK from the manufacturer.

i'm working on a very simple time attendance web application
i'm saving the StartTime into SQL Server 05 Column.
what i need is to save the diffrence between the StartTime and the EndTime when the user is entering his leaving time.
my table is like that
Col1 :: col2 :: col3 :: col4
EmployeeID::StartTime::EndTime::TimeDiff
is there is any way i can do this

You can calculate different between DateTime instance from your application and store it in the database or you might make your TimeDiff column computed so that it stores difference between EndTime and StartTime (for example in seconds). You can use DATEDIFF[^] function for calculating difference between two dates in sql server.

As Giorgi said, it may be best to get SQL to do this for you.
If you want to do it in C# (I assume so as you're asking in the C# forum), look at the Timespan struct.
DateTime now = DateTime.Now;
DateTime then = DateTime.Now.AddHours(-1);
TimeSpan duration = now - then;
MessageBox.Show(duration.ToString());

Hey all -
I'm a total newb, and I'm trying to use the WSUS API to connect to a specified WSUS Server and "do stuff". The problem is that it currently uses the currently logged on use to connect to the WSUS server, which fails. If I do a "run as" on the program, and use the correct credentials, it works.
So, the question is how to prompt for credentials (command line) and connect to the WSUS server?
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Collections;
using Microsoft.UpdateServices;
using Microsoft.UpdateServices.Administration;
namespace WSUS_Check
{
class Program
{
static void Main(string[] args)
{
string Server;
int Port, ans, count;
bool Secure;
ArrayList TGIDs;
System.Console.WriteLine("*******************************************************************************");
System.Console.WriteLine("Custom WSUS Check, v0.01");
System.Console.WriteLine("*******************************************************************************");
System.Console.WriteLine();
System.Console.Write("WSUS Server: ");
Server = System.Console.ReadLine();
System.Console.Write("Port: ");
Port = int.Parse(System.Console.ReadLine());
do
{
System.Console.Write("Secure [1\\0]: ");
ans = int.Parse(System.Console.ReadLine());
} while ( (ans != 1) && (ans != 0) );
if (ans == 1)
{
Secure = true;
}
else
{
Secure = false;
}
IUpdateServer Host;
try
{
Host = AdminProxy.GetUpdateServer(Server, Secure, Port);
System.Console.WriteLine("Connected to " + Host.Name.ToString() + " [WSUS v. " + Host.Version.ToString() + "]");
System.Console.WriteLine();
System.Console.WriteLine("Client groups on " + Host.Name.ToString() + ":");
ComputerTargetGroupCollection CTC = Host.GetComputerTargetGroups();
count = 0;
foreach (IComputerTargetGroup TG in CTC)
{
System.Console.WriteLine("[" + count + "] " + TG.Name.ToString() + ", " + TG.Id.ToString());
count++;
}
}
catch (Exception e)
{
System.Console.WriteLine();
System.Console.WriteLine(e.Message);
}
System.Console.WriteLine();
System.Console.WriteLine();
System.Console.WriteLine("Press any key to continue... ");
System.Console.ReadKey();
}
}
}

Since this is a console app, you could just create a batch file to run your program as who ever with the runas command.
That way you don't need to have have to modify your code.
Just because we can; does not mean we should.
|
|
|
|
|
Sure, that's one way, but not the way I'd like to see it done.
The code has to be modified anyways, midas well do it now. Plus I can learn the an auth. peice from this, which will be cool.

Did you find a solution for this? I am facing the same problem. If you found a solution can you share the sample code.

...? Thats not even a question, and it sounds like some kind of malware keylogging thing.
Perhaps if you could elaborate a little more.

yes , when we use internet all urls , chatting , e-mail's should be recorded into a file and that file should be invisible to see until we go to the "FOLDER OPTIONS" and enable to show files

1 - ask real questions, as in full sentences
2 - if you want to do something that could be used for extreme nastiness, you better explain your benign use for it and pray we believe you.

I'll give you the benifit of the doubt and assume your not up to anything nasty!
As a service it's pretty much impossible for reasons described here[^].
If your application has a legitimate purpose, then your end user won't object to a program running from the tray at least, in which case this[^] and this[^] may be of use.

I'd assume the worst, when someone posts like that. I'd hate to be the one who gave the code that stole your credit card no.

Good Day,
Whenever I want to read a file, I always use:
byte[] stream = File.ReadAllBytes(path);
It worked fine for me in my past projects but now, I am reading files that are 200mb in size and File.ReadAllBytes won't present the progress of the file reading.
Thru googling, I found out that I can use BinaryReader to read files. But I don't know how to read it using the "OLD APPROACH" like using a loop and read the file chunk by chunk so I can compute for the progress.
So basically, my question is, how to use BinaryReader to read files using a a loop. 
Thanks!
It is said that the most complex structures built by mankind are software systems. This is not generally appreciated because most people cannot see them. Maybe that's a good thing because if we saw them as buildings, we'd deem many of them unsafe.

Its simple, you have a buffer of size N and you try to read N bytes from your file into this little buffer. The Stream.Read(...) method returns and int representing the number of bytes actualy read, so you then use this int to write the correct number of bytes from your buffer to your BinaryStream or whatever your using. You then keep copying bytes until you reach the end. It should look something like this:
FileStream fs = new FileStream(...);
BinaryStream bs = new BinaryStream();
byte[] buffer = new byte[1024];
int read = 0;
while(bs.Position < fs.Length)
{
read = fs.Read(buffer, 0, 1024);
bs.Write(buffer, 0, read);
}
fs.Close();

I have an application that I setup by adding a DataSet .xsd file to my project and then dragging tables from the Server Explorer data connections area. This automatically sets up the connection string in about a dozen places. Now I want the user to be able to point to the database they want to use, but I'm not sure where the connection needs to be updated.
The connection string exist in the main solution's
Properties\Settings.settings,<br />
Properties\Settings.designer.cs
In the data access layer project's
app.config<br />
Properties\Settings.settings,<br />
Properties\Settings.designer.cs
How would i update this value? From where (and how) should i read it when the app starts up, or if its being updated programatically would i have to save it to a custom file and read if from there?

Frst, work out when you need it by, then work out a budget. Finally post your estimates here and give the rest of us a laugh.
