FtpWebRequest request is triggering a Invalid URI format - exception

From the command line I can successfully connect via FTP to my host using either
ftp.domain.com or domain.com
C:\Users\Aaron>ftp
ftp> open
To domain.com
Connected to domain.com.
220 FTP Server ready.
User (domain.com:(none)): Login failed.
ftp> close
221 Goodbye.
ftp> open
To ftp.domain.com
Connected to ftp.domain.com.
220 FTP Server ready.
User (ftp.domain.com:(none)): Login failed.
ftp> close
221 Goodbye.
ftp> quit
I escaped entering the password above and scrubbed the domain, but it still shows for each connection I was successful. When I run this code in Visual studio, I get the invalid URI.
Here is my code I've tried in C#
Uri target = new Uri("ftp://ftp.domain.com/");
FtpWebRequest requestDir = (FtpWebRequest)FtpWebRequest.Create(target);
requestDir.Credentials = new NetworkCredential("user", "pass");
Uri target = new Uri("ftp://ftp.domain.com/");
FtpWebRequest requestDir = (FtpWebRequest)FtpWebRequest.Create(target);
requestDir.Credentials = new NetworkCredential("user", "pass");
The requested URI is invalid for this FTP command
I've looked on here as there are many like this, but I've tried all of them (I think) and I just keep on getting this error. Any ideas?
Thanks!

I was able to get it working with the help of some other posts here and a lot of troubleshooting. I now have this working and have moved on to new errors. Here is the code for the successful FTP upload:
reqCakes = (FtpWebRequest)WebRequest.Create("ftp://domain.com/images/" + "koala.jpg");
reqCakes.UseBinary = true;
reqCakes.Method = WebRequestMethods.Ftp.UploadFile;
reqCakes.Credentials = new NetworkCredential("user", "pass");
BinaryReader rdrCakes = new BinaryReader(File.Open(fileToOpen, FileMode.Open));
rdrCakes.Close();
byte[] cakeData = File.ReadAllBytes(fileToOpen);
reqCakes.ContentLength = cakeData.Length;
Stream reqStream = reqCakes.GetRequestStream();
reqStream.Write(cakeData, 0, cakeData.Length);
reqStream.Close();

MySQL Connector/Net Bulk Uploader not finding file on remote server

I have pored through many pages trying to find an answer but have had no luck. I have a .NET page built in C# that has been working fine until a few days ago. Now it isn't working and I'm pulling my hair out to find out why.
The page has a file uploader that uploads a .csv file and saves it to a folder on the web server. Then it uses the MySQL Bulk Uploader to insert the records into the database on another server.
I have confirmed the file is uploading to the correct folder, but when MySQL tries to insert the records, it fails with the message "File 'E:\inetpub\wwwroot\training\data_uploads\filename.csv' not found (Errcode: 2 - No such file or directory)"
This page has worked for several years without any problem, but I updated some of the NuGet packages and removed some that were not being used, and now it's stopped working. What am I missing? Is there a package or a .dll I need to add back in? Unfortunately, I don't remember what I removed.
Here's the code I'm using:
protected void btnGo_Click(object sender, EventArgs e)
{
try
{
//if file is selected for upload
if (btnSelectFile.HasFile)
{
//upload data file to server
string path = string.Concat(Server.MapPath("~/data_uploads/" + btnSelectFile.FileName));
btnSelectFile.SaveAs(path);
string conString = ConfigurationManager.ConnectionStrings["nameOfConnectionString"].ConnectionString;
MySqlConnection conn = new MySqlConnection(conString);
conn.Open();
//get rid of old data
MySqlCommand truncateTerms = new MySqlCommand("TRUNCATE terms_temp;", conn);
truncateTerms.ExecuteNonQuery();
//create bulk uploader and set parameters
var bl = new MySqlBulkLoader(conn);
bl.TableName = "terms_temp";
bl.FieldTerminator = ",";
bl.FieldQuotationCharacter = '"';
bl.LineTerminator = "\r\n";
bl.FileName = path;
bl.NumberOfLinesToSkip = 2;
//insert data
var inserted = bl.Load(); //This is where it fails
conn.Close();
//do some other stuff
catch (Exception ex)
{
Label1.ForeColor = System.Drawing.Color.Red;
Label1.Text = ex.Message.ToString();
}
}
If you're bulk-loading a file that's stored on the web server, not the database server, you need to set MySqlBulkLoader.Local = true, to indicate that the file is local to the database client. Otherwise, the server will give an error that the file isn't found.
For security reasons you will also need to set AllowLoadLocalInfile=true in your connection string to enable this feature.

How to send a file greater than 25 MB using Java Mail API

I am designing an application which sends Email with attachments using Gmail's smtp host. But when the file is larger than 25 MB, then I get an error saying that "552-5.2.3 Your message exceeded Google's message size limits. Please visit https://support.google.com/mail/?p=MaxSizeError to view our size guidelines.
188sm2692677pfg.11 -gsmtp"
final String username = "username#gmail.com";
final String password = "password";
Properties prop = new Properties();
prop.put("mail.smtp.host", "smtp.gmail.com");
prop.put("mail.smtp.port", "587");
prop.put("mail.smtp.auth", "true");
prop.put("mail.smtp.starttls.enable", "true");
Session session = Session.getInstance(prop,
new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(username, password);
}
});
try {
Message message = new MimeMessage(session);
message.setFrom(new InternetAddress("username#gmail.com"));
message.setRecipients(
Message.RecipientType.TO,
InternetAddress.parse("receiver address"));
message.setSubject("This mail is a test mail");
BodyPart messageBodyPart = new MimeBodyPart();
messageBodyPart.setText("Message");

multipart.addBodyPart(messageBodyPart);

String filename = <Path>;
DataSource source = new FileDataSource(filename);
messageBodyPart.setDataHandler(new DataHandler(source));
messageBodyPart.setFileName(filename);
multipart.addBodyPart(messageBodyPart);

Transport.send(message);
} catch (MessagingException e) {
JOptionPane.showMessageDialog(null, e.getMessage());
}
Is there any way of sending files greater than gmail's limit of 25 MB?
Can I change the file size upload limit from account settings or can I do something like any file will be uploaded as a drive link?
The user friendly way is probably to upload the file somewhere and add a link to the file in the mail.
It's also possible to split the file in several smaller parts and send each part in its own mail. The recipient then needs to join the files together again.
Zip-archivers can usually split large files into several zip-files that can then be join together again.
There's also raw splitting and joining. I haven't come across split commands built in to operating system distributions as standard. But your program could split the file in any way you desire.
Joining the files is then quite easy under Windows or Unix (Linux and others) operating systems. In Windows you go to the command prompt and use "copy": copy file1+file2+file3 finalfile In Unix you use "cat": cat file1 file2 file3 > finalfile
No. That is hard limit. Gmail itself states:
If your file is greater than 25 MB, Gmail automatically adds a Google Drive link in the email instead of including it as an attachment
That is what I would recommend for you as well, upload the file somewhere and paste a link in the mail. Options may be: Google Drive, Mega, Dropbox, S3, ...
Other than that there is nothing you can do.

Web Socket Connection Disconnecting - ApacheAMQ

I'm trying to use STOMP with Apache AMQ as I was hoping web sockets would give me a better performance than the typicalorg.activemq.Amq Ajax connection.
Anyway, my activemq config file has the proper entry
<transportConnector name="ws" uri="ws://0.0.0.0:61614?maximumConnections=1000&wireFormat.maxFrameSize=104857600"/>
And I'm connecting to it via the following means:
function amqWebSocketConn() {
var url = "ws://my.ip.address:61614/stomp";
var client = Stomp.client(url);
var connect_callback = function() {
alert('connected to stomp');
client.subscribe("topic://MY.TOPIC",callback);
var callback = function(message) {
if (message.body) {
alert("got message with body " + message.body);
} else { alert("got empty message"); }
};
};
client.connect("", "", connect_callback);
}
When I first open up the web browser & navigate to http://localhost:8161/admin/connections.jsp It shows the following:
Name Remote Address Active Slow
ID:mymachine-58770-1406129136930-4:9 StompSocket_657224557 true false
Shortly there after - it removes itself. Is there something else I need such as a heart beat to keep the connection alive?
Using
var amq = org.activemq.Amq;
amq.init({
uri : '/myDomain/amq',
timeout : 50,
clientId : (new Date()).getTime().toString()
});
Kept the connection up for the TCP AJAX Connection
I have faced similar problem, solved it using this
client.heartbeat.incoming = 0;
client.heartbeat.outgoing = 0;
You have to add these two lines before connect.
Even after this I have seen disconnection after 5-10 minutes, if there are no incoming messages. To solve that you have to implement ondisconnect call back of connect method.
client.connect('','',connect_callback,function(frame){
//Connection Lost
console.log(frame);
//Reconnect and subscribe again from here
});
This is successfully working in my application.

How do I SSIS WMI Event Watcher Query for a network folder?

What I'm trying to do in SSIS is have a WMI Event Watcher Task which watches a folder for a file to be created, then does something with it. The primary part is the "watching the folder for file creation".
I have a network folder (full path): \\srvblah10\main\child\target\
All the sites I've gone to has this as an example:
SELECT * FROM __InstanceCreationEvent WITHIN 10
WHERE TargetInstance ISA "CIM_DirectoryContainsFile"
AND TargetInstance.GroupComponent = "Win32_Directory.Name=\"d:\\\\NewFiles\""
Since the folder is a network folder, I can't provide the physical disk letter. So is there a way to use a similar WQL query but for network folder paths as opposed to physical folder paths?
You have to map the drive with a dos command:
net use s: \srvblah10\main\child\target\ /user dotnetN00b Pa$$word
then you can the WMI Event Watcher Task to watch it.
I was trying to do this for awhile, and finally gave up on trying to use the SSIS WMI Event Watcher task, and just wrote the equivalent in a Script task. The issue that was the challenge was getting the WMI Event Watcher to make the remote connection with specific user credentials that I wanted to obtain from a configuration section (not hard code into the package).
The second issue that was going to make not using a script difficult was simply translating the network share, into the local path name on the server, which the Event Watcher requires. You'll see from the scrip below, everything is accomplished with a minimal of effort.
Just an additional heads up, make sure to include the DTS.Variables the script uses in the ReadOnlyVariables (as normal). The code below requires three DTS variables, for example if you are trying to watch for files being dropped in the following location \copernicus\dropoff\SAP\Import, then you would set the variables as shown below:
User::ServerName - the hostname of the server where the share lives
(copernicus)
User::ShareName - the name of the network share
(dropoff)
User::ImportPath - the directory path of the directory to
watch for new files in (/SAP/Import)
public void Main()
{
string localPath = "";
try
{
ConnectionOptions connection = new ConnectionOptions();
connection.Username = "<valid username here>";
connection.Password = "<password here>";
connection.Authority = "ntlmdomain:<your domain name here>";
ManagementScope scope = new ManagementScope(#"\\" + Dts.Variables["User::FileServerName"].Value.ToString() + #"\root\CIMV2", connection);
scope.Connect();
/// Retrieve the local path of the network share from the file server
///
string queryStr = string.Format("SELECT Path FROM Win32_Share WHERE Name='{0}'", Dts.Variables["User::ShareName"].Value.ToString());
ManagementObjectSearcher mosLocalPath = new ManagementObjectSearcher(scope, new ObjectQuery(queryStr));
foreach (ManagementObject elements in mosLocalPath.Get())
{
localPath = elements["Path"].ToString();
}
queryStr = string.Format(
"SELECT * FROM __InstanceCreationEvent WITHIN 10 WHERE Targetinstance ISA 'CIM_DirectoryContainsFile' and TargetInstance.GroupComponent=\"Win32_Directory.Name='{0}{1}'\"",
localPath.Replace(#"\", #"\\"),
Dts.Variables["User::ImportPath"].Value.ToString().Replace(#"\", #"\\")); // query requires each seperator to be a double back slash
ManagementEventWatcher watcher = new ManagementEventWatcher(scope, new WqlEventQuery(queryStr));
ManagementBaseObject eventObj = watcher.WaitForNextEvent();
// Cancel the event subscription
watcher.Stop();
Dts.TaskResult = (int)ScriptResults.Success;
}
catch (ManagementException err)
{
Dts.Events.FireError((int)err.ErrorCode, "WMI File Watcher", "An error occurred while trying to receive an event: " + err.Message, String.Empty, 0);
Dts.TaskResult = (int)ScriptResults.Failure;
}
catch (System.UnauthorizedAccessException unauthorizedErr)
{
Dts.Events.FireError((int)ManagementStatus.AccessDenied, "WMI File Watcher", "Connection error (user name or password might be incorrect): " + unauthorizedErr.Message, String.Empty, 0);
Dts.TaskResult = (int)ScriptResults.Failure;
}
}

NotificationHubNotFoundException Windows Phone 8

While I´ve been trying to make the basic notification hub tutorial work on my Windows Phone solution with the following code
var channel = HttpNotificationChannel.Find("MyPushChannel3");
if (channel == null)
{
channel = new HttpNotificationChannel("MyPushChannel3");
channel.Open();
channel.BindToShellToast();
}
channel.ChannelUriUpdated += new EventHandler<NotificationChannelUriEventArgs>(async (o, args) =>
{
var hub = new NotificationHub("http://messaging-ns.servicebus.windows.net/messagingt", "---MY CONECTION STRING---");
await hub.RegisterNativeAsync(args.ChannelUri.ToString());
});
I get a NotificationHubNotFoundException in the await line with the following message
HTTP request failed.
HTTP Details:
Status: 404
Reason: Not Found
Full content: 404No service is hosted at the specified address..TrackingId:2e4b1100-18de-4b24-bbec-68516ddc3b60_G4,TimeStamp:2/2/2014 1:30:23 AM
I tried a number of options for the first parameter of the NotificationHub constructor called "notificationHubPath" with no luck to get my app registered. Anyone has faced this error in the past. Unfortunately there are not enough documentation in how does this constructor works in MDSN.
Thanks
When creating the NotificationHub type object, try by passing just the hub name with the connection string, not the whole address:
var hub = new NotificationHub("messagingt", "---CONECTION STRING---");
I had the same issue, and after close/open VS2013, restart PC and change Wifi/3g connection it worked again like before... strange, i suppose that was a internet connection issue.
you can use fiddler to show more information, i forgot in my case...
