You can also check out http://www.codeproject.com/useritems/filedownloader.asp[^].
You almost have things setup correctly, but the CredentailCache.DefaultCredentials will supply the request object with the default system credentials, not the username and password required by the web site.
In order to do that, you will need to do something like this:
Uri uri = new Uri(url);
CredentialCache credCache = new CredentialCache();
NetworkCredential userCred = new NetworkCredential(username, password, domain);
credCache.Add(uri, "Basic", userCred); The "NTLM" in the call is a string that specifies the authentication type. The valid choices are "NTLM", "Digest", and "Basic". You will need to use the type that is appropriate for your specific case.
Also, make sure that you don't need a proxy to be specified.

Hi,
i am not able to fire xpath queries (SelectSingleNode method with namespace object) to a SOAP xml. It complains about a namespace problem. here is a sample
<soap:envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:body>
<setresponse xmlns="http://tempuri.org/">
<smessageid>EEF0AFFE-A9F5-41A2-AE82-4601E3E2465F
i want the data in the "sMessageID" element. Any idea??

Your XML snippet isn't visible. Please modify your post by either replacing all < with &lt; or check the "Ignore HTML tags in this message" option beneath the smilie selection. Furthermore it will be helpful to see XPath expression your currently using.

So sorry for the inconvinience caused. Please find the xml below
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<SetResponse xmlns="http://tempuri.org/">
<sMessageID>EEF0AFFE-A9F5-41A2-AE82-4601E3E2465F</sMessageID>
</SetResponse>
</soap:Body>
</soap:Envelope>
xpath i am trying to use the "sMessageID" element
/soap:Envelope/soap:Body/SetResponse/sMessageID
Regards,
James

I'm not sure, but I think the problem is that the SetResponse and sMessageID element are in the "http://tempuri.org/" namespace (defined as standard namespace without prefix) but this doesn't reflect in your XPath expression.
Try to use the SelectSingleNode overload that additionally takes a XmlNamespaceManager instance. Add entries for the pair (soap "http://schemas.xmlsoap.org/soap/envelope/") and (somePrefix "http://tempuri.org/") and use the somePrefix in your XPath: /soap:Envelope/soap:Body/somePrefix:SetResponse/somePrefix:sMessageID.

Hi,
I have already done all the namespace mechanisms known to me.The problem is , if i add a namespace on my own, it should be applicable to all parts in the xpaths, not just the last couple of parts. I think, we need to find a way to specify that "soap" prefix is not a namespace and it is just an element name. Any way thanks for your reply

I'm a current MCAD student. Hope someone can help me with a small query. I am working on an application that saves student records to an xml file. Through using an Xml Schema, a dataset generated from the xml schema, a new student row and the WriteXml method, I can save a new record to an xml file.
However, if I display an existing record to a series of textboxes and want to amend the record, how do I save the amended record back to the xml file. If I find a student row using the Student ID, populate the textboxes with the details, then use WriteXml method again, that saves a new record to the file instead of amending the existing records. I therefore conclude this is the wrong way of doing things so I am asking if anyone can point me in the right direction.
Is there another dataset method I should be using that I am not aware of to update an existing record. The NewStudentRow() method adds a new record, is there another method for updating?
Grateful for any help.

Hi,
When a network cable is plugged or unplugged from Lan card windows displays a message "LAN is now connected" or "Network cable is unplugged" in system tray. My question is how can i build an application which display such messages when a cable is unplugged from network card.
Thanx in advance.

Hi,
I want to create a process using a user's login info. In managed C++ there is a "CreateProcessWithLogonW" function but I want to accomplish my task with managed code.
Is there any equavalent method for "CreateProcessWithLogonW"? How can I start a process using a logon info?
thanks,

Use an overload of Process.Start that takes an instance of ProcessStartInfo class which provides properties for logon information.

Thanks for your reply but it is not clear to me which attributes of ProcessStarInfo has to be supplied with user's login name and password.
Simply, I need running a program with another user's privileges. When I use "runas" DOS command I am prompted to enter the user's password. That's the problem. I don't want to supply the password during runtime. I want the job to be done automatically.
thanks,

The properties are called UserName and Password. I saw right now that both are new in framework version 2.0 so that's probably the reason why you didn't find them. In case you're using a framework version prior 2.0, there's probably no managed way and you have to p/invoke the unmanaged function mentioned in your first post.

In case you don't already knew it, take a look at http://www.pinvoke.net[^]. It's a great help when you have to work with unmanaged apis.

Hi all,
I want to check whether computer is connected to the network or not. I use a boolean method IsNetworkConnected() as shown below. I wonder if this method is OK, if not can you suggest any method?
public bool IsNetworkConnected()<br />
{<br />
IPAddress IPAd;<br />
ipHostInfo = Dns.GetHostEntry(Dns.GetHostName());<br />
IPAd = ipHostInfo.AddressList[0];<br />
<br />
if (IPAd.ToString() == "127.0.0.1")<br />
{<br />
return false;<br />
}<br />
else<br />
{<br />
return true;<br />
}<br />
}<br />
|
|
|
|
|
i am sure this method will work.
regards

It really depends on what you mean by "connected to the network". If you are only interested in determining if the network is available (ie, the cable is plugged in and the NIC is getting a signal) you can use the NetworkAvailabilityChangedEventHandler delegate[^].
Using the AddressList property as you show above isn't the most reliable way to check as it may not return the addresses in the order you are expecting, so AddressList[0] isn't guaranteed to be the loopback address. (The better way to test if it is the loopback address is also to do if (IPAd == IPAddress.Loopback) or if (IPAddress.IsLoopback(IPAd)).)
If you need to know if you are connected to the internet, the best options are to try to browse to a website or ping a known address.
Using ping:
bool internetAvailable = false;
Ping pinger = new Ping();
PingOptions pingOptions = new PingOptions(1, true);
byte[] pingResults = new byte[2];
PingReply pingReply = pinger.Send("www.microsoft.com", 25000, pingResults, pingOptions);
if (pingReply.Status == IPStatus.Success)
{
internetAvailable = true;
}
Using website:
bool internetAvailable = false;
Uri requestUri = new UriBuilder("http", "www.microsoft.com").Uri;
HttpWebRequest connectivityCheck = WebRequest.Create(requestUri) as HttpWebRequest;
connectivityCheck.Timeout = 25000;
HttpWebResponse connectivityResponse = connectivityCheck.GetResponse() as HttpWebResponse;
if (connectivityResponse.StatusCode == HttpStatusCode.OK)
{
if (!connectivityResponse.IsFromCache)
{
internetAvailable = true;
}
}
-----------------------------
In just two days, tomorrow will be yesterday.

Thank you for your reply, I dont need internet avaliability, but it is useful.
I think I can use NetworkAvailabilityChangedEventHandler, as you wrote. Thanks again;)

Hi,
is there a workaround for the following problem that occurs on .Net 2.0:
DirectoryInfo di = new DirectoryInfo(@"\\server.sub.domain.net\folder");
FileInfo[] aFiles = di.GetFiles("*.html");
On 1.1 this works fine, but version 2.0 it gives
************** Exception Text **************
System.IO.IOException: The network path was not found.
at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)
If I replace name from UNC path with IP address or "short name" like \\server\, also 2.0 version starts to work.
Is there any fix available for this?
Br,
mjma
