Nope. There's nothing in the .NET BCL that will do this. In order to use IP, you have to use the system's network stack. In order to do that, you have to setup and start the connection outside of your application.
If you really want to transfer files and your writing code for both the server and client side of your app, look into finding an implementation of ZModem or XModem. This will allow you to transfer files over the direct modem connection without using TCP/IP or FTP.

Try to do some research on SLIP. Think I've seen some code for going with an IP connection over a serial cable. As far as I remember it was WinAPI though. So go from SLIP and WinAPI and maybe MS implemented smth similar in .NET. Good Luck.

Only by implementing the TCP stack yourself. I wouldn't recommend this.
If you want to make use of the operating system's facilities, you must use the Remote Access Services API, e.g. RasDial. There is no managed wrapper for this API, but you can find out how to use it from .NET at PInvoke.NET[^].

if you make a connetion by directly accces to modem you can not use IP address. You access and control modem via serial port using AT commands. You by-pass TCPIP stack provided by operating system. You have to implement yourself it in this way.
You should make connection using RAS (Remote Access Service). You have to make a new connection -manually or programaticaly- and can use it. RasDial, etc...
I would send some sample code in .Net if you want.

I don't think they are available any more. Every time I look I get taken to Visual Studio 2008.
The Visual Studio 2008 Express edition can be downloaded from here:
http://www.microsoft.com/express/download/default.aspx[^]

|

I'll add to Colin's post. VS2008 can target .NET 2 code, so you don't need to worry about not being able to continue with VS2005 code.

For sure, they are not free. You have to purchase MSDN Subscription for the same. You may however like to try the freely available Express equivalents subject to the EULA that are displayed.

Hi all,
Under my machine I have installed .Net framework v1.1, v2.0 and v3.0
How can I know which version is being used by my applications ?
Thanks
|
|

Hi,
this is only a partial answer to your question:
string s=Environment.Version.ToString();
if (s=="1.1.4322.573") s=s+" (= 1.1 without Service Packs)";
else if(s=="1.1.4322.2032") s=s+" (= 1.1 with SP1)";
else if(s.StartsWith("1.1.")) s=s+" (= unknown 1.1 flavor)";
else if(s=="2.0.50727.832") s=s+" (= 2.0 without Service Packs)";
else if(s=="2.0.50727.1433") s=s+" (= 2.0 with SP1)";
else if(s.StartsWith("2.0.")) s=s+" (= unknown 2.0 flavor)";
Console.WriteLine(s);
It lacks information on 1.0, 3.0 and 3.5, and does not answer the question from
outside the app.
I too would like to know how to programmatically ask an EXE which Framework it needs
without launching it.

The question is complicated by the fact that version 3.0 and 3.5 do not update the JIT compiler nor the base class libraries. Officially, anyway - 3.5 shipped simultaneously with (and requires) 2.0 SP1 which does update the CLR and BCL.
To determine the version of the CLR required, you can use the Assembly.ImageRuntimeVersion property, if you load the assembly using reflection. To determine if libraries from 3.0 or 3.5 are required you will need to use GetReferencedAssemblies and inspect the assemblies that are being loaded.

I'm guessing I have made a basic error here: A friend asked me if I could write a little app to query a MOHAA console. Connection works perfectly first time but then hangs after the second send/receive.
Any advice (and especially with an explanation!) VERY VERY gratefully received.

IPAddress GroupAddress = IPAddress.Parse(ConfigurationManager.AppSettings["ip"]);<br />
Int32 GroupPort = Int32.Parse(ConfigurationManager.AppSettings["port"]);<br />
IPEndPoint ep = new IPEndPoint(GroupAddress, GroupPort);<br />
<br />
String message = "ÿÿÿÿ" + (Char)2 + "rcon " +<br />
ConfigurationManager.AppSettings["password"] +<br />
" serverinfo";<br />
<br />
Byte[] sBuffer = Encoding.Default.GetBytes(message);<br />
udp.Send(sBuffer, sBuffer.Length, ep);<br />
Byte[] rcvBytes = udp.Receive(ref ep);<br />
String returnData = Encoding.ASCII.GetString(rcvBytes);<br />
String[] returnDataSplit = Regex.Split(returnData, "\n", RegexOptions.IgnoreCase);<br />
foreach (String str in returnDataSplit)<br />
{<br />
Console.WriteLine(str);<br />

A couple of possibilities come to mind:
1. You didn't include your initialization code. Something there could be hanging.
2. Your receive code assumes that the response from the server fits into one datagram.
Take a look at the UdpClient class[^] for a sample UdpClient.

I need to send a e-mail with attachment from my win application.
Can I check (and how) whether connection to internet exists?
So far I'm dealing it like this:
try<br />
{<br />
SendMailMethod(to,from, attachement);<br />
}<br />
catch(exception)<br />
{<br />
}
Is there a better (proper) way to do it?

Ping the gateway or a well-known server:

using System;
using System.Net;
using System.Net.NetworkInformation;
using System.Text;
namespace Examples.System.Net.NetworkInformation.PingTest
{
public class PingExample
{
// args[0] can be an IPaddress or host name.
public static void Main (string[] args)
{
Ping pingSender = new Ping ();
PingOptions options = new PingOptions ();
// Use the default Ttl value which is 128,
// but change the fragmentation behavior.
options.DontFragment = true;
// Create a buffer of 32 bytes of data to be transmitted.
string data = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa";
byte[] buffer = Encoding.ASCII.GetBytes (data);
int timeout = 120;
PingReply reply = pingSender.Send (args[0], timeout, buffer, options);
if (reply.Status == IPStatus.Success)
{
Console.WriteLine ("Address: {0}", reply.Address.ToString ());
Console.WriteLine ("RoundTrip time: {0}", reply.RoundtripTime);
Console.WriteLine ("Time to live: {0}", reply.Options.Ttl);
Console.WriteLine ("Don't fragment: {0}", reply.Options.DontFragment);

How does one put text on a progressbar control? I can't seem to find a property or function for that.
-- modified at 9:38 Sunday 25th November, 2007
I was already using a user control to give me a smooth bar (got the code from the microsoft site). I just added some extra code to allow me to set and draw the text.

Hi John,
text labels are not supported by the ProgressBar control.
This article[^] shows it is rather easy to add a progress indicator to a Label tho.

EventLog or custom log (text or XML document on predefined place)?
I am preparing for 70-536 exam, and I am working on some home brew exception handling for personal project, and I was wandering which solution is better?
In company of my first employment text logs in bin folder were canon, at least for errors and warnings.
In company in which I work now, EventLog is used almost exclusively.
None of the programmers in both companies couldn't explain their opinions and preferences with good arguments, first were simplicity advocates and second are somewhat coding purists/exhibitionist.

Hi,
logging everything to the EventLog isn't so good if you ask me. It should only be used if it is really system critical and is only appropriate for very few logs. Logging to a file is better. But it should be done in some user specific directory. Vista for example doesn't like it much if you change the programs folder.
Have a look at log4net[^]. With it you can "just log" in your application. The configuration file than controls which logs of what level in which class get logged to a file, the EventLog or some other destination. You can also easiliy change this behaviour once your application is deployed.

I use my own XML-based logging.
Some of us are old dogs and EventLog is a new trick.
If you get in the habit of using EventLog what will you do when you need to write a non-Windows app?
