The specified string is not in the form required for an e-mail address

Fri, 07 Sep 2007 16:44:04 Z

I have searched and searched and searched for an answer to this problem...

I have been using the System.Net.Mail namespace for quite a while to send emails from my websites. A problem occurs though on certain (VALID) email addresses. For example, when the name field of the email address has a dot (.) in it (example: my.name@email.com), an exception is raised when this address is added to the TO property of the MailAdddress object. It seems the dot between my and name causes the exception.

Please note that these are valid email addresses, but the MailAddress object considers them to be invalid.

Any suggestions/workarounds?

Error Message: The specified string is not in the form required for an e-mail address.

Delete file from FTP with PROXY

Thu, 26 Nov 2009 11:54:10 Z

Hello. I need to delete file from FTP with option to pass Proxy. I have found code for upload file but can't find for delete.
Here is the code for upload that works for me (the main function calls first):

    Private Function CreateProxyAndCheckBypass(ByVal bypassLocal As Boolean, ByVal ftpIp As String, ByVal ftpName As String) As WebProxy
        Dim bypassList As String() = New String() {";*." & ftpIp}
        Dim proxy As New WebProxy(ftpIp, bypassLocal, bypassList)
        If Not proxy.IsBypassed(New Uri(ftpName)) Then
                 Return Nothing        'Bypass not working
        Else
                 Return proxy           'Bypass is working
        End If
    End Function

    Public Function ftpUpload(ByVal ftpIP As String, ByVal ftpUserName As String, ByVal ftpPassword As String, ByVal fileNameToUpload As String, ByVal filePathToUpload As String) As Boolean
        Dim ftpName As String = "ftp://" & ftpIP
        Try
            Using client As New System.Net.WebClient()
                Dim ur As New System.Uri(ftpName)
                client.Proxy = CreateProxyAndCheckBypass(True, ftpIP, ftpName)
                client.Credentials = New System.Net.NetworkCredential(ftpUserName, ftpPassword)
                client.UploadFile((ftpName & "/") + fileNameToUpload, "STOR", filePathToUpload)
            End Using
            Return True
        Catch ex As Exception
            Return False
        End Try
    End Function

Any help very appreciated. Thanks

Ip connection not found

Thu, 19 Nov 2009 17:48:51 Z

Hey,

I made a little client and server so i could chat between 2computers, using ip connection.

It works fine, but i doesn't work with everyone.
I tried to login from different computers, but it only works when i try from my dad's computer and also with one of my friends computer.

So i'm wondering what the problem could be, that other computers can't find my server?
I gues it has something to do with properties but don't know what yet.

thnx..

Windows Server 2008 outlook comException 0x8000401A

Fri, 27 Nov 2009 12:01:12 Z

Hey guys,

i'm having a problem with the windows server 2008. The same code does work in server 2003. Last weak we switched to 2008. Now i am getting the following error:

System.Runtime.InteropServices.COMException (0x8000401A): Retrieving the COM class factory for component with CLSID {0006F03A-0000-0000-C000-000000000046} failed due to the following error: 8000401a.

I'm trying to start a new outlook application, but it seems that the server won't let me. However, i'm impersonating to the server, tried several account( system, interactive, network etc. etc) But nothing seems to help.
I've also modified the dcomcnfg for excel (same problem, if is skip outlook). And gave everything rights for everything.

Now... here comes the strange part: when i remote login tothe server as the impersonated user (acc-dbuser) then it will work fine. The proces is going perfect. So i was thinking, it must be something with rights. BUT, if i log in as a(ny random) user to the server,the process also runs, and it starts opening outlook as acc-dbuser(impersonated user). However, if there is no session on the server, it holds and stops doing everything.

Any clues? I can't seem to find the problem!
The code:

Server Error in '/FormsAuthorization' Application... Request for the permission of type 'System.Web.AspNetHostingPermission...' failed.

Thu, 26 Nov 2009 22:48:01 Z

Please note that I have been abled to get a forms authorization website working without a problem using Visual Studio 2008 with IIS 6.0 on Microsoft Windows Xp (cf. http://www.codeproject.com/KB/web-security/RolesFormsAuthorization.aspx); however, when I attempt to access the website on a Windows 7 server http://localhost/FormsAuthorization/Admin/Default.aspx[^] using IIS 7.5 with Visual Studio 2010 Beta 2, I receive the following errors:

Also, when I open the existing website in Visual Studio 2010 Beta 2, it has the following error messages (there are no error messages when I open the website on IIS 6.0/Windows Xp with Visual Studio 2008):

Error 4 Value cannot be null.  Parameter name: frameworkName

Does anyone have any suggestions? Why would it work on IIS 6.0 but not on IIS 7.5? I've tried modifying the permissions on IIS 7.5 Manager .NET Trust Levels from Full (internal) to Minimal, but that results in the website giving the error "Debugging is not supported under current trust level settings." Please note that I'm new to IIS 7.5 and in fact to Microsoft web servers in general, so if you have any ideas they would be greatly appreciated.

How do I authenticate with a WCF service in a different domain that is using Integrated Authentication?

Wed, 25 Nov 2009 23:20:28 Z

I have a WPF client that connects to a set of WCF web services. We have a Dev, Test, Volume and Production domains, with the services available on a server in each domain. The domains have only partial trust relationships.

The goal is to have the client connect the the services of any domain. If the client and server are on the same domain then the Default Network Credentials should be sent to authenticate/authorize. If the server is in a different domain, then it should challenge the user for credentials, much in the same way Internet Explorer does when you hit a site on a different domain with Integrated Security set.

At the moment i'm trying to fetch the clients credentials by setting DisplayInitializationUI() when creating an instance of the ClientBase for my service.

Client client = new Client(); // <- the wcf ClientBase implementation for the serivce.

client.Endpoint.Behaviors.Remove<ClientCredentials>();

client.Endpoint.Behaviors.Add<ClientCredentialsEx>();

client.DisplayInitializationUI();

client.InnerChannel.Open();

The ClientCredentialsEx class.

public class ClientCredentialsEx : ClientCredentials
{
	public ClientCredentialsEx() : base() { }
	public ClientCredentialsEx(ClientCredentialsEx other) : base(\

	public override void ApplyClientBehavior(ServiceEndpoint serviceEndpoint, ClientRuntime behavior)
	{
		behavior.InteractiveChannelInitializers.Add(new ShowCredentialUI());
		base.ApplyClientBehavior(serviceEndpoint, behavior);
	}
	protected override ClientCredentials CloneCore()
	{
		return new ClientCredentialsEx(this);
	}
}

The ShowCredentialUI class implements IInteractiveChannelInitializer. The business end of the class is the BeginDisplayInitializationUI method;

public IAsyncResult BeginDisplayInitializationUI(IClientChannel channel, AsyncCallback callback, object state)
{
	string host = "";
	CREDUI_INFO info = new CREDUI_INFO();
	string username = string.Empty, password = string.Empty;

	CREDUI_FLAGS flags = CREDUI_FLAGS.GENERIC_CREDENTIALS | 
			CREDUI_FLAGS.SHOW_SAVE_CHECK_BOX |
			CREDUI_FLAGS.EXPECT_CONFIRMATION;

	bool savePwd = false;

	// PromptForCredentials calls interop credui to challenge the user for username/password/smartcard.
	CredUIReturnCodes result = PromptForCredentials(ref info, host, 0, ref username,ref password, ref savePwd, flags);


	ChannelParameterCollection collection = channel.GetProperty<ChannelParameterCollection>();
	collection.Add(new NetworkCredential(username, password));
	return new AsyncResult();
}

The problem is when I investigate the iis logs, the credentials are never sent. I know that I am missing something crucial. Has anyone had a similar scenario implemented successfully? Is there an easier way to achieve this?

Thanks for reading!

How do i make a virtual "shared folder" (not a windows folder) using code ?

Thu, 26 Nov 2009 09:43:29 Z

Hello

first off, what i really would like to do, is to share a windows 7/vista/2008 [saved search] - but that's impossible...

I would like to create a shared folder, available on my network eg. \\mycomputer\virtualshare

the files in that folder should be dynamic (opposed to static files/folders in windows)

example:

1. PC2 accesses the shared folder \\PC1\Share

2. a script or some code generates virtual files, which populates the share

3. PC2 downloads start to download File1

4. PC1 links/streams the filecontent to PC2

is this possible ?

Thanks !

Send Data Via Sockets

Tue, 24 Nov 2009 22:35:49 Z

I am trying to make simple peer to peer chat.

But I don't know the sockets at all. I tried several examples found on Google but wasn't able to study much from them.

I have to Programs Client + Server

Server

Dim XListener As New Sockets.TcpListener(12345)

        XListener.Start()
        Do While True
            XListener.AcceptSocket()

        Loop

Client

  Dim myclient As New Sockets.TcpClient
        Dim SendData As Sockets.Socket
        Dim sendBytes As [Byte]() = System.Text.Encoding.ASCII.GetBytes("TesT")
        myclient.Connect("127.0.0.1", 12345)
        If myclient.Connected Then
            MsgBox("Connected")
            SendData.BeginSend(sendBytes, 0, sendBytes.Length, Sockets.SocketFlags.None, AddressOf ("What should I write here??"), what should I write here??)
        Else
            MsgBox("eror")
        End If

    End Sub

I am able to connect but not able to send text, because I don't understand the meaning of - AddressOf - Function.

Please write the very simple example how I can send text via sockets and receive .

Thanks in advance

Tcp Client / listener application

Wed, 25 Nov 2009 21:07:50 Z

Hi,,
I need to develop an application which will use TCP to transfer data between applications.
The scenario is application A will need to pass data to application B, who in turn will need to pass on to application C.
Application C, will need to reply with valid data to application B, after which application B will do some processing and then pass the result back to application A.

Furthermore application B will need to accept requests from a number of clients and then return the associated data to the calling client.

I have looked at a number of samples, but I can't find a sample to suit my scenario. I have achieve the communication from application A to b, from b to C, but need to return the data back to application A.

I have very little knowledge of tcp and sockets, so and example as to how to do this would be great.

Any help would be appreciated.

Proxy with no WSDL?

Thu, 26 Nov 2009 00:00:32 Z

I need to call a web service, but it has no WSDL. All I have is a PHP code snippet, and the SOAP request. Unfortunately, I don't know WCF well enough to create a proxy from this. Can someone help?

Here is the PHP code snippet:

$soapclient = new nusoap_client('serviceURL');

$parameters= array('preferences'=>array('version_id'=>'1','utc_offset'=>'-5'),'options'=>array('include-copyright'=>'both'));

$results = $soapclient->call('methodName',$parameters);

Here is a sample SOAP request:

<?xml version="1.0" encoding="ISO-8859-1"?>
<SOAP-ENV:Envelope SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" 
        xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" 
        xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
        xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/">
  <SOAP-ENV:Body>
    <ns5857:methodName xmlns:ns5857="http://tempuri.org">
      <preferences>
        <version_id xsi:type="xsd:string">1</version_id>

Any help would be much appreciated!

Thanks!

Publishing WCF via http in a windows service results in "System.Runtime.Remoting.RemotingException: Tcp channel protocol violation: expecting preamble"

Tue, 24 Nov 2009 19:18:38 Z

Hi all,
I'm creating a WCF service that I will ultimately publish via http, and named pipes. I'm just trying to get the http portion working at the moment. I receive this error in my browser when I browse to my endpoint at http://localhost:10000/SpidertracksTaskRunner.

.NET System.Runtime.Remoting.RemotingException: Tcp channel protocol violation: expecting preamble. at System.Runtime.Remoting.Channels.Tcp.TcpSocketHandler.ReadAndMatchPreamble() at System.Runtime.Remoting.Channels.Tcp.TcpSocketHandler.ReadVersionAndOperation(UInt16& operation) at System.Runtime.Remoting.Channels.Tcp.TcpServerSocketHandler.ReadHeaders() at System.Runtime.Remoting.Channels.Tcp.TcpServerTransportSink.ServiceRequest(Object state) at System.Runtime.Remoting.Channels.SocketHandler.ProcessRequestNow()

I've created numerous services with Java before, but this is my first attempt with .NET 3.5 and WCF. I have the config below, everything looks to be in order according to the book "Pro C# 2008 and the .NET 3.5 Platform", but I'm just not getting any data. Here is my relevant config section. As you can see, I've created an http endpoint, so why does it seem to be expecting connections via the tcp protocol? Any help would be greatly appreciated, I get absolutely no logging or console output, so I have no idea what could be causing this problem.

Thanks,
Todd

Video Creator

Sat, 21 Nov 2009 19:47:27 Z

Hi,

I want to make an application which can create video using its own intelligence.

Explaination:
User will provide number of images,text,audio sound, In short all the multimedia options as well as user will select the size of resulted video along with the type of the resulted video extention(.mov, .avi etc).
Now the aplication will be selecting all the inputed resources and will create video ,which will be of specified size and having extention as per the users requirement.

I'm confused that where do i start from and where can i find API which will help me going ahead.

I need the API in asp.net-c#.

Please help me out ASAP.

Thanks in Advance....

.Net Framework version problems

Tue, 24 Nov 2009 11:16:21 Z

Hi All,

I did an application to manage many connection.

On my machine, I have the Visual Studio 9 and I'm developping using .Net Framework 3.5. However, in the datacenter where the application is running, it has Visual Studio 8, .Net Framework 2.0 and .Net Framework 3.5.

I compliled the application on my machine and I'm starting the application directly by .exe in the datacenter.

The problem is that the application is using .Net Framework 2.0 in the datacenter, even I had compiled with .Net 3.5.

I tried to remove .Net 2.0, but the Windows informed me that is not possible.

How can I run the application using .Net 3.5 without install Visual Studio 9?

Thanks!

Can a Windows Service be notified about the result os WCF Service it hosts?

Tue, 24 Nov 2009 15:31:13 Z

I was thinking about to host a WCF Service in a Windows Service that would do a hard work with 5 threads and listen on WCF for interruption requests or progress of execution requested by other WCF Services on same Service Arquiteture hosted on other apps like a Web app.

A need that web app can request the queue of execution. The progress done.

The logic of execution needs stay on the WCF service assembly and not in a method of Windows Service in this case?
Could you put in the right direction on this?

PPP question

Tue, 24 Nov 2009 14:07:19 Z

Hello All,

I’m not sure if this is right forum for my question, if it is not kindly point me to correct one.

I have a software application that needs to communicate with some devices, installed on remote locations. Network on these locations is accessible through PSTN line only.

I have a requirement in my software that it should automatically establish the dialup connection with targeted location, if user wishes to communicate with one of the device on targeted location. Again if user wishes to communicate with another device, installed on different location then my software should disconnect the existing dialup connection and should establish the dialup connection with new location, where new device is installed (my software will have location information about devices like- phone number , user name, password etc.).

I have some ideas about “ATs” commands but I’m sure these are not enough for successful communication with device on remote location.

I was not able to find useful information using google. I’d appreciate if someone can provide the pointer, I should start from.

Thank you for your help.

Regards,
Gurmit

Get Lat Lon boundaries of a google map picture

Tue, 24 Nov 2009 09:27:32 Z

I am acquiring a google earth image in vb.Net using the following:

      imgImage.Load("http://maps.google.com/staticmap?center=" _
                      + dblLat.ToString + "," + dblLong.ToString + _
                      "&zoom=" + intZoom.ToString + _
                      "&size=512x512&maptype=satellite")

where imgImage is a PictureBox .net object.
I need to know what the width and height of the image returned is in NauticalMiles. My understanding is that:
- ZoomFactor=1 means 360deg, which means 360*60NM
- ZoomFactor=2 means 180deg, which means 180*60NM
- etc.....
- ZoomFactor=5 should be equivalent to 1350NM

When I actually check this distance on GoogleEarth I get something closer to 1100NM from North to South and from East to West.
How can I get a better accuracy on the boundaries of my image?
By the way, I will be essentially working on large zooms (around 100NM resolution), so it's ok for me to ignore earth curvature.
Thanks for your help,
C

Active Directory ChangePassword COM Exception error

Tue, 11 Dec 2007 14:43:28 Z

Doing an intranet web page for my company that allows to change their password. I got it to work yesterday for about 3 minutes but then it stopped. Here's the error:

System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.Runtime.InteropServices.COMException (0x80070547): Configuration information could not be read from the domain controller, either because the machine is unavailable, or access has been denied. (Exception from HRESULT: 0x80070547)

Here's my code.

string currentUserName = (((string)Context.User.Identity.Name).Split('\\'))[1];

string OldPassword = this.txtOldPassword.Text;

string NewPassword = this.txtNewPassword.Text;

ChangePassword(currentUserName, "MyCompanyDomain", OldPassword, NewPassword);

public void ChangePassword(string strLogin, string strRootPath, string strOldPasswd, string strNewPasswd)

{

try

{

strRootPath = String.Format(@"LDAP://{0}", strRootPath);

DirectoryEntry objRootEntry = new DirectoryEntry(strRootPath, strLogin, strOldPasswd, AuthenticationTypes.Secure);

DirectorySearcher objADSearcher = new DirectorySearcher(objRootEntry);

objADSearcher.Filter = String.Format(@"(&(objectClass=user)(anr={0}))", strLogin);

SearchResult objResult = objADSearcher.FindOne();

DirectoryEntry objLoginEntry = (objResult != null) ? objResult.GetDirectoryEntry() : null;

if (objLoginEntry != null)

{

object obj = objLoginEntry.InvokeSet("ChangePassword", new object[] { strOldPasswd, strNewPasswd });

objLoginEntry.CommitChanges();

obj = null;

}

objRootEntry = null;

objADSearcher = null;

objResult = null;

objLoginEntry = null;

}

catch (System.Exception abc)

{

this.lblErrors.Text = abc.ToString();

}

Anyone have any help on the error message? I've been Googling answers for about 3 hours, but nothing seems to point me in the right direction...

Thanks!

OUI Extended ethertype packet on RAW sockets

Sat, 21 Nov 2009 01:33:52 Z

Whenever I try and find out about using RAW sockets all I find is information relating to Sec issues, building and sending IP packets, and the restrictions that Windows places on these.

I need to send and recieve OUI extended ethertype packets for working with networked devices. Is it possible to do this from a user space application using the .Net framework?

Does windows try to block the use of such protocols?
