hi,
i have some problems using the functions
LsaEnumerateLogonSessions
LsaGetLogonSessionData.
is there a simple sample for using this functions.
maybe the problem is my structure (forgive me the vb-code)?
<structlayout(layoutkind.sequential, charset:="CharSet.Auto)"> _
Private Structure SECURITY_LOGON_SESSION_DATA
Dim Size As UInt64
Dim LogonId As LUID
Dim UserName As LSA_UNICODE_STRING
Dim LogonDomain As LSA_UNICODE_STRING
Dim AuthenticationPackage As LSA_UNICODE_STRING
Dim LogonType As UInt64
Dim Session As UInt64
Dim Sid As IntPtr
Dim LogonTime As Int64
Dim LogonServer As LSA_UNICODE_STRING
Dim DnsDomainName As LSA_UNICODE_STRING
Dim Upn As LSA_UNICODE_STRING
End Structure
many thanks in advance.
regards, thilo.

Hello,
How can I format the decimal output to 4 decimal points only?
Thank you.
|
|
|
|
|
Use the formatting in the ToString method:
string shortPi = Math.PI.ToString("0.0000");
---
b { font-weight: normal; }
|
|
|
|
|
// Create a NumberFormatInfo object and set several of its
// properties that apply to numbers.
NumberFormatInfo provider = new NumberFormatInfo( );
string formatter = "{0,22} {1}";
// These properties will affect the conversion.
provider.NegativeSign = "minus ";
provider.NumberDecimalSeparator = " point ";
// These properties will not be applied.
provider.NumberDecimalDigits = 4;
provider.NumberGroupSeparator = ".";
provider.NumberGroupSizes = new int[ ] { 3 };
Convert.ToString( ObjDouble, provider ) );

Hi
I have the following problem: I generate an XML file that has a CDATA section that contains character references (characters created by the XmlTextWriter in order to conform to well formatted XML and are in the form: , �). When I read the xml with an XmlTextReader I get the escaped strings instead of the characters. (I get "�" instead of '\0' for example)
using reader.ReadChars(...) has the same effect.
Any ideas?

Hey all,
I'm new to web app dev so I'll ask a simple question..
I created a simple chat application with client & server sockets.
after initialation & establishing the connection, I send text message to the server.
when I send the first message, the server gets it and displays it,
now, I realized that after the client sends the first message to the server, I need to reconnect to it again in order to send another message(s)..
The question is Do I need to reconnect to the server everytime, even though I have the server & client socket objects initialized...
my client code is like this:
private void btnSend_Click(object sender, System.EventArgs e)
{
btnConnect_Click(sender, e);//without this proc. I can send only 1 msg
try{
string msg = TxtSnd.Text+"<eof>";
byte[] byteData = Encoding.ASCII.GetBytes(msg);
lblstts.Text = "Sendeing...";//status label
clientMe.Send(byteData);
TxtSnd.Text = "";//delete text from TextBox
}catch(Exception Ex)
{
MessageBox.Show(Ex.Message);
}
}

The short answer is no.
The long answer is maybe. This is possible only if all the methods you write in this .DLL are written to accept a key and validate it. This is something I don't think you want to do in every property and method you expose.

So long as both assemblies have a strong name, you can add a StrongNameIdentityPermissionAttribute[^] to the class library at the assembly level. As a result, only applications signed with your private key will be able to access the library.

Hello,
I have two decimal numbers, and I want to use mod function to get
an integer number. But it seems it's only available for SQL.
Is there a nice way of deviding two decimals and rounding off the result to a nearest integer?
Thank you

Hi,
I am trying to use a C# Windows Forms application as a DDE Client.
At present I'm using the follwing code to initiate a session with the DDE Server...
ushort app = GlobalAddAtom(Marshal.StringToHGlobalAnsi(appname));
ushort topic = GlobalAddAtom(Marshal.StringToHGlobalAnsi(topicname));
this.packedParam = PackDDElParam(WM_DDE_INITIATE, (System.IntPtr)app, (System.IntPtr)topic);
SendMessage(dtaProcess, WM_DDE_INITIATE, Process.GetCurrentProcess().MainWindowHandle, this.packedParam);
This should return a WM_DDE_ACK message to the main thread as follows...
protected override void WndProc(ref Message m)
{
\\WM_DDE_ACK = 996
if (m.Msg == 996)
{
MessageBox.Show("");
}
else
{
base.WndProc (ref m);
}
}
I do not receive the WM_DDE_ACK message. Also, the PackDDElParam method (user32.dll) returns a negative value. Is this correct?

You'll have to go to the article that you downloaded it from, scroll to the bottom of the page and you'll find a discussion board just like this one. Post a question asking for additional information there. Articles are, for the most part, supported by the people that wrote them.

when i use procedure
CommandType is procedure
and then run ExecuteNonQuery()
the return value of ExecuteNonQuery() is always -1
so the return value of ExecuteNonQuery is useless when use procedure?
|
|
|
|
|
It executes the query and just return the no of rows affected.
|
|
|
|
|
|
Hai
For UPDATE, INSERT, and DELETE statements, the return value is the number of rows affected by the command. For all other types of statements, the return value is -1. If a rollback occurs, the return value is also -1.
For more information See
SqlCommand.ExecuteNonQuery Method[^]
|
|
|
|
|
|
the procedure execute correctly and the data in DB changed.
but the return value is -1
why?
return value just useful when execute sql query?

I have a parent class, Base with 2 child classes, Child1, and Child2.
Base has a public int iNo. I init Child1 from another class. So Child1 inits Base.
Now, in Child1, I set Base.iNo = 10. Then i create the second child class, Child2 from Child1. Now, in Child2, when I call Base.iNo, i don't get 10.
I know the problem is that the child classes works with 2 seperate instances of the Base class, but how can i resolve this.
i want both child classes to inherit from the same Base instance. How do i do this.?
Thank you

You inherit a class, not an object. Child1 and Child2 only inherits the definition of Base, Child1 objects and Child2 objects still are separeate objects. It's the same way as if you have two separate Base objects, they each have there own set of members, although they come from the same class.
If you want to share a member across objects, you have to declare it as static.
