Somebody told me that the login/logout times of past 3 weeks are stored somewhere on the pc:

No, they're not.

The only place that would have anything like this would be the Security event log, which IIRC, by default, doesn't log user logon/logoff events.

ActiveDirectory does not keep track of the last 3 weeks either.

Well, the answer is still usefull;

I;m trying to dectect when the PC was turned on; by sifting and screening through all the logs, i can detect activity;

Security log might be best bet;

Re: Wrapping VOIP traffic

Not really. The system being turned on will only show in the security log as a SYSTEM account login event, IF the machine is configured to log these events. Shutdown may or may not show up, but usually doesn't. Again, it depends on what is being logged.

There really isn't any 100% foolproof way to get what you want unless you specifically setup group policy in an ActiveDirectory environment to log all this stuff.

Well, you have a problem. You need your wrapper installed on both clients. You can't just wrap it on your end and expect the receiver to know what to do with the packet. Also, you can't write this in C# since it's going to be a driver you install into the network stack. You have to use C++ to do this.

Hi pals,

I am trying to create a small utility which can block folders from direct access. For this purpose, I have a textbox in my form and a two buttons namely: browse and apply.

Now, whenever the user clicks on browse, the Open file dialog box appears and whatever folder has been selected by the user is displayed in the textbox.

Now, comes the major problem. In order to block the particular folder selected by the user, I have to generate two batch files (files with .bat extension) on the location of the folder, that has to be locked. Like if the folder to be blocked is in this 'C:\\myfolder\\subfolder\\lockfolder' location, where lockfolder is the particular folder which I have to lock, then in that case, I have to generate a batch file in 'C:\\my folder\\subfolder\' that will lock the folder 'lockfolder'.

Any Idea how to do that..... please recommend.

Sorry for my poor english,
Cheers to you,
Rajdeep.NET Smile | :)

.bat files are just renamed text files. Look into the StreamWriter class

I'm getting very suspicious about what you're trying to do.

I would suggest that people here stop helping you until answer the question I asked in my last post to you[^].

So, just to recap. You're trying to:

a) Copy the currently running exe
b) Hide the console window
c) Block access to a folder

If this isn't something you shouldn't be writing then im the pope.

Yeah, with you're skill level, and total lack of knowledge in how Windows works, you're never going to pull this off.

You need to be more specific. How did you connect to the excel? Was it the first row you lost?

Dear

I Use like this

string strCnn="";
strCnn = "Provider=Microsoft.Jet.OLEDB.4.0;";
strCnn += " Data source=" + openFileDialog1.FileName;
strCnn += ";Extended Properties=Excel 8.0;";
OleDbConnection cn = new OleDbConnection(strCnn);
cn.Open();
string strsql="";
strsql = "SELECT * FROM [sheet1$]";
OleDbDataAdapter da = new OleDbDataAdapter(strsql, cn);
DataTable dt = new DataTable();
da.Fill(dt);
int i=0;
Application.DoEvents();
for (int k = 0; k < dt.Rows.Count; k++)
{
i++;
dgvSource.Rows.Add(i.ToString(), dt.Rows[k][0].ToString());

}

I got only 9 rows, but in fact in excel has 10 rows

Thanks

Socheat

Which row is missing? Is it the first one? If it is then you will notice that it is being used as the column titles. Use strCnn += ";Extended Properties=\"Excel 8.0;HDR=No;\""; to stop using the first row as the column headers, the default is HDR=Yes.
