You have to supply the username AND PASSWORD in order to do this. The only way to get the users password is to ask for it and have them type it in. Then you can restart the service.

But, in the case of Windows XP, you can have multiple users logged in on the machine at any time. How is your service going to handle this situation? You really can't stop the service and change the account every time someone logs in.

If you have a process that needs to run under the users account, create your application as a normal console or Windows Forms .EXE and put a shortcut to it in the Startup folder. The app runs under the users security context when the user logs in.

Unfortunately it's not that easy, there is more to it then that.

hi
i am having problem when i am trying to write something on remote location using .net thread.
e.g. i have a central location letsay MachineName|MachineIP/SharedDrive.
and i am creating a thread on click of a button which i need to write some information on that location.

i have also added a node <identity impersonate="true" username="Domain\User" password="*******"> in web.config of my application.

and i have also given credential in <machine.config>--<processmodel enable="true" username="SameInWeb.Config" password="SameInWeb.Config">

but it is giving the following exception:
The system detected a possible attempt to compromise security. Please ensure that you can contact the server that authenticated you.

below is my method which i am calling on a separate thread.
private void WriteSomeThingToRemoteLocation ()

{
FileStream fileStream = null;
BinaryFormatter binaryFormatter = null;
System.Object systemObject = null;
System.Object obj = new object();
lock ( obj )
{
string _contractLocaterKey = Guid.NewGuid().ToString().Replace( "-", "" );

string fullPath = @"\\MyMachineIP\SharedDrive" + "\\" + _contractLocaterKey + ".dat";
try
{
fileStream = new FileStream( fullPath, FileMode.CreateNew, FileAccess.Write );
binaryFormatter = new BinaryFormatter();

systemObject = new object();
systemObject = "Hello this is testing1";
binaryFormatter.Serialize( fileStream, systemObject );

systemObject = new object();
systemObject = "Hello this is testing2";
binaryFormatter.Serialize( fileStream, systemObject );
}
// catch(Exception ex)
// {
// avoided for getting noticed what happened;
// }
finally
{
if ( fileStream != null )
{
fileStream.Close();
fileStream = null;
}
binaryFormatter = null;
systemObject = null;
}
}
}

please help in this matter as i am stucking in the problem from more than 3 days.

this thing is happening OK :
1. if i call this method directly on another method.
2. if i call this method in a console application .
3. if i call this method on a thread in a console application.

any help would be highly appreciated.

thanks

Working with Excel

I have a VB 6 code with me. The code is playing with excel. It generates worksheets and adds templates to them, sets cell values, etc. I want to rewrite the entire code into C#.Net. For that I have used Microsoft Excel 11.0 COM reference. (This is same in VB6). The problem is that I cannot find code in C#.Net equivalent to VB6 counterpart. Examples are given below:
oBook.Worksheets("General")
or this
oSheet.Rows(2).Copy oSheet.Rows(i)
There are many examples like this.
Either I don't know how to write this in .Net or there is no equivalent.

Does anybody know, where I can learn how to use Excel in .Net 2003 in good amount of depth so that I can convert any code in VB6 to .Net 2003?

Anil

Copy a directory somewhere

Simple question. Smile | :)

Is there a command to copy a directory in a different path without doing this manually on files and sub-directory contained there?
I've not found any copy command on System::IO::Directory ... it's strange! Confused | :confused:

Thank you

Russell

yes...like MS-DOS command xcopy does.
Of course, I can use directly that command, ... but I'm trying to understand if there is an implemented function that does this copy that I still not know.
Thank you

As fas as I know there is not such built-in function but if you search codeproject for xcopy you will find what you need.

Another idea for you is to do a simple hack - use the Process class and start a process using the xcopy command like you mentioned in some of your other posts.

I actually have done this in a build app I wrote.

I've also used the process class for doing FTP and LPR (using the built-in Windows commands, since there are no easy classes in the framework for this).

return Message;

if (EncodingFrom.CodePage == EncodingTo.CodePage)
return Message;

Decoder decoder = Encoding.UTF8.GetDecoder();
byte[] bytes = Encoding.UTF8.GetBytes(Message);
char[] chars = new char[bytes.Length * 5];//*2

int bytesUsed, charsUsed;
bool completed;

decoder.Convert(bytes, 0, bytes.Length,
chars, 0, chars.Length, true,
out bytesUsed, out charsUsed, out completed);

string ResultString = new string(chars, 0, charsUsed);

return ResultString;

For hours and minutes only, without dates and seconds:

DateTime first;
DateTime second;

if (first.Hour > second.Hour)
{
    //first is later
}
else
    if (first.Hour == second.Hour)
        if (first.Minute > second.Minute)
        {
            //first is later
        }
        else
            if (first.Minute == second.Minute)
            {
                //they are the same
            }
            else
            {
                //second is later
