hi,
i'm currently working on a project following the concept of Float's Mobile Agent - where you can control a sony ericsson phone (t610) from a PC via Bluetooth. i was hoping if anyone can help me code in C# on how to do the same on either a Nokia 6600 or P800 (both Symbian-operated). i'm thinking of using Java as a middleware too. i would really appreciate your help ^_^

Hello guys,
I like to retrieve MAC addresses arround my network without the use of SendARP. The network is huge and contains a lot of subnets. Since ARP doesn't go to other subnets I need to find another method.
Programs like nbtstat -a <hostname> and getmac /s <hostname> do what they have to do. Altought I like to have it my program.
Any idea's?
Another option is to use getmac /s <hostname> /fo csv and get the output. How do I manage that?
Small upate:
I don't want to use WMI to retrieve the MAC address.
Thanks in advance.

I found a sort of solution. I hope to help other people out with this...
<br />
string sComputerName = "";
try<br />
{<br />
Process p = new Process();<br />
string cmd = "";<br />
cmd = System.Environment.GetFolderPath(Environment.SpecialFolder.System) + "\\cmd.exe";<br />
p.StartInfo.FileName = cmd;<br />
p.StartInfo.Arguments = "/C nbtstat -a " + sComputerName + "";<br />
p.StartInfo.RedirectStandardOutput = true;<br />
p.StartInfo.UseShellExecute = false;<br />
p.StartInfo.CreateNoWindow = true;<br />
p.Start();<br />
p.WaitForExit(1000);<br />
string output = p.StandardOutput.ReadToEnd();<br />
<br />
if (CharCount(output, "MAC Address = ") != 0)
{<br />
int iPos = output.IndexOf("MAC Address = ");<br />
sMacAddress = Mid(output, iPos + 14, 17);<br />
}<br />
}<br />
catch (Exception) {}<br />
<br />
public static string Mid(string strParam, int startIndex, int length)<br />
{<br />
string tmpstr = strParam.Substring(startIndex, length);<br />
return tmpstr;<br />
}<br />
<br />
public static int CharCount(string strSource, string strToCount)<br />
{<br />
int iCount = 0;<br />
int iPos = strSource.IndexOf(strToCount);<br />
while (iPos != -1)<br />
{<br />
iCount++;<br />
strSource = strSource.Substring(iPos + 1);<br />
iPos = strSource.IndexOf(strToCount);<br />
}<br />
return iCount;<br />
}

I am interested in a way, using the .NET Framework classes, to obtain a MAC address based on an IP number. Knowing an IP number, I need to know to extrapolate the MAC address. How can this be done with the .NET Framework and C#? I know that the MAC is not in the Request object, I need some guidance on getting the MAC *after* I have used the Request object to get the IP number. I have found some about using the "System.Management" Namespace already.
I'm assuming the machine running the function and the remote machine we are trying to obtain the physical address of are on the same network segment and are not separated by a firewall.
Any thoughts about a solution to the problem?

Well, you can use the script code above with 2 changes.
Change:
string sComputerName = ""; // The hostname
To:
string sIPaddress = "";
and change:
p.StartInfo.Arguments = "/C nbtstat -a " + sComputerName + "";
to:
p.StartInfo.Arguments = "/C nbtstat -A " + sIPaddress + "";
Note the capital A in the last line.
Good luck.

Hello,
I´m trying to use the SQL Server 2005 Express in my C# 2005 Express Project and I´m getting nuts! In my project I created the Tables I need but know I really don´t know hoe to establish a connection and make select or insert statements?! In the learning Videos from microsoft the do everything with Databinding in the Designer but I have to leran how to make those things manually by code. In my Book about c# they use OleDBConnectio, OleDBDataReader and OleDBCommand to connect and work with an Access MDB. But I have to use SQL Server. In other examples I found they use DataAdapter...an I really don´t know what´s the correct way? Is there anywhere a simple example that shows how to connect to a local installed SQL Server and make a select statement, show the Data from the selectstatement in a grid or something else and make in insert into a table? Or can anyone show me how to do that? Normaly it´s not my way to ask such questions but I really become nuts and be doubt about my programming knowledge...
Thank you very much

Hi!
Yes, starting can be a bitch... 
You can't say one choice is "the correct" way, because you can achieve what you want in many different ways.
You can use the OleDB* classes to communicate with a SQL Server just like you would with Access. The only thing that's different (in the beginning, at least) is the connection string you'll have to specify.
With an mdb file you just include datasource='...path to your file...', but that doesn't work with SQL server.
Since I can't remember all the parts of a connection string for a given database, I usually take a look at http://www.connectionstrings.com/[^] to find the correct connection string.
Everything else is just a matter of reading the class documentation...

Hi Guies,
How to read integer from keyboard in C#.
Thanks in Advance...
|
|
|
|

For console programing you hava to use
using System.Console.;
& then use
ch = System.Console.Read(); //return charater
Or
str = System.Console.ReadLine(); //return string

I want to take integer value and not char or string.
Actually System.Console.Read() reads kay pressed and not int.
|
|
|
|
|
Then use int.Parse() to convert it.

if you are trying to accept only numeric values in your text box, you can use the e.Handle = true of KeyPressEventArgs to cancel the keypress event.
You can try the code below.
string strnum = "0123456789";
if (strnum.IndexOf(e.KeyChar.ToString())<0)
{
e.Handled = true;
}

Can anyone tell me how, if it is possible, to pass a method as an argument for another method?
|
|
|
|
|
Hello,
Firstly define method type:
public delegate int TypeName([Type arg[,[Type arg,...]]]);
This is your method type.
Now define one object of this type
private TypeName myObject;
& also define one method which has declaration as your method type
Note: Object & method are different so use different names for them.
Now initialize object
myObject = new TypeName(MethodName);
now you can pass this object as argument & use same methodtype for calling method for that argument.

Use a delegate:
class A
{
public delegate void SomeDelegate();
public void MethodWithDelegateParam(SomeDelegate del)
{
del();
}
}
and in client code:
class B
{
public void MyMethod()
{
DoSomething();
}
public static void Main()
{
B b = new B();
A a = new A();
a.MethodWithDelegateParam(new A.SomeDelegate(b.MyMethod));
}
}

I am working on a web browser project, i have done the work as when new tab button is clicked, a new tab is created with a browser, but the navigation occurs only in the first tab browser. Is there any way to correct it?
|
|
|
|
|
I don't have the detail of your project and what technology you are using to achieve the display of HTML, but I suspect that you don't keep track of the currently active tab page. What I suggest is that you have a private variable that keeps track of all the tab pages (a collection, for instance) and another one to keep track of the current tab page index. When the user creates a new tab, update your variables accordingly.
