How to Check if file pattern exist in C# SSIS package [duplicate]

I have a for loop container within my ssis package which contains a script and a sql task.
I have 3 variables.
source.string = this is folder location
file.string = i have used wildcard = *.csv
exist.int = defaulted to 0
I have the innitexpression value set to #Exists=1
and the evalexpression value set to #Exists=1
in the script I have set it to look at source variable and if file.string variable exists then set exist variable to 1
problem is it just loops it should only loop if no file there. cant see how I've done this wrong it was working before I changed the variable to be a wildcard *.csv
I have tested it using another variable which contains a filename rather than a wildcard and it works correctly the issue is when looking for a wildcard for the filename followed by the extension. why is this? can I not pass through a wildcard variable?
my script task is
public void Main()
{
// TODO: Add your code here
string Filepath = Dts.Variables["User::Source"].Value.ToString()
+ Dts.Variables["User::file"].Value.ToString();
if (
File.Exists(Filepath))
{
Dts.Variables["User::Exists"].Value = 1;
}
/// MessageBox.Show (Filepath);
/// MessageBox.Show(Dts.Variables["Exists"].Value.ToString());
Dts.TaskResult = (int)ScriptResults.Success;
}
#region ScriptResults declaration
/// <summary>
/// This enum provides a convenient shorthand within the scope of this class for setting the
/// result of the script.
///
/// This code was generated automatically.
/// </summary>
enum ScriptResults
{
Success = Microsoft.SqlServer.Dts.Runtime.DTSExecResult.Success,
Failure = Microsoft.SqlServer.Dts.Runtime.DTSExecResult.Failure
};
#endregion
}
}

Based on comments above i made 2 different solutions. The solution for you right now would be no. 2
This one can search for a specific file based on multiple files in your path. It need some tweaking but can be used if you wanna check if a specific file exists with wildcard
This one evaluates to true if any wildcard file is found.
C# Code 1
Using System.IO:
string Filepath = Dts.Variables["User::Source"].Value.ToString();
string WildCard = Dts.Variables["User::file"].Value.ToString(); // In Text form #"*.txt";
string fullpath = Filepath + WildCard;
//With for loop
string txtFile = null;
// Gets all files with wildcard
string[] allfiles = Directory.GetFiles(Filepath, WildCard);
//Loop through all files and set the filename in txtFile. Do whatever you want here
foreach(string fileName in allfiles)
{
//Check if a file contains something, it could be a prefixed name you only want
if(fileName.Contains("txt"))
{
txtFile = fileName;
if(File.Exists(txtFile))
{
Dts.Variables["User::Exists"].Value = 1;
}
}
}
C# Code 2
Using System.IO;
Using System.Linq;
string Filepath = Dts.Variables["User::Source"].Value.ToString();
string WildCard = Dts.Variables["User::file"].Value.ToString(); //In text form "*.txt";
string fullpath = Filepath + WildCard;
//With bool
bool exists = Directory.EnumerateFiles(Filepath, WildCard).Any();
if(exists == true)
{
Dts.Variables["User::Exists"].Value = 1;
}
MessageBox.Show (Filepath);
MessageBox.Show(Dts.Variables["Exists"].Value.ToString());

Sending a message using IBM MQ, getting 2059 error or hang on construction of Queue Manager

I'm tasked with sending a test message to an (as yet) unknown MQ endpoint.
I've stood a trial version of IBM WebSphere MQ (v8.0.0.5) on a server, which I believe is configured correctly.
However, given the code included below I get either the exception:
An unhandled exception of type 'IBM.WMQ.MQException' occurred in
amqmdnet.dll
Additional information: 2059
Or if I am on the server itself using localhost instead of the remote server name, the constructor line hangs.
This is C#:
Hashtable connectionProperties = new Hashtable();
string connectionType = MQC.TRANSPORT_MQSERIES_MANAGED
connectionProperties.Add(MQC.TRANSPORT_PROPERTY, connectionType);
// Set up the rest of the connection properties, based on the
// connection type requested
switch (_connectionType)
{
case MQC.TRANSPORT_MQSERIES_BINDINGS:
break;
case MQC.TRANSPORT_MQSERIES_CLIENT:
case MQC.TRANSPORT_MQSERIES_XACLIENT:
case MQC.TRANSPORT_MQSERIES_MANAGED:
connectionProperties.Add(MQC.HOST_NAME_PROPERTY, "server.com");
connectionProperties.Add(MQC.CHANNEL_PROPERTY, "SYSTEM.DEF.CLNTCONN");
break;
}
MQQueueManager qMgr = new MQQueueManager("test", connectionProperties);
MqClientTest mqClientTest=new MqClientTest("TEST_QM","localhost", "SYSTEM.DEF.CLNTCONN");
Is there anything we're missing in this?
Update 1:
In the amqerr01.log file in the errors folder, we now have the text:
AMQ6183: An internal WebSphere MQ error has occurred.
Update 2:
The "internal WebSphere MQ error" was likely due to my probing the 1414 port to see if the port was "up" and listening. Seems it was and it obviously didn't like me doing that.
Update 3:
#Roger suggested I use 127.0.0.1 and capitals, which I've now applied - and changed the example above to reflect.
#JoshMc kindly pointed to a second AMQERR01.LOG file within the Queue Manager folder. I now get the error:
14/11/2017 15:35:08 - Process(336.6) User(xxxx)
Program(amqrmppa.exe)
Host(xxxx) Installation(xxxx)
VRMF(8.0.0.5) QMgr(TEST_QM)
AMQ9519: Channel 'SYSTEM.DEF.CLNTCONN' not found.
EXPLANATION: The requested operation failed because the program could
not find a definition of channel 'SYSTEM.DEF.CLNTCONN'.
TEST_QM is my Queue Manager, with the default (?) channel SYSTEM.DEF.CLNTCONN

With IBM MQ there are always a pair of channels that work together. For example if one MQ Queue Manager needs to send to message to another queue manager it would normally have a SDR (Sender) channel defined, which would point to a RCVR (Receiver) channel with the same name on the other queue manager.
For a MQ client connection the client application side of the channel is called a MQCD, and the MQ Queue Manager side is a SVRCONN (Server Connection) channel. The client side MQCD can be specified in a few different ways. The way you are demonstrating in the example you posted is programmatically specifying the MQCD information (channel name, hostname, etc).
An alternate way to specify the information is by pointing to a CCDT (Client Channel Definition Table) which is commonly referred to as a Channel Table, this is where a CLNTCONN channel would be used, since you are not using a Channel table I'll move on to why you are getting an error, but at the end of this answer I'll provide more details on Channel Tables.
In summary your application should not be specifying a CLNTCONN channel as the MQC.CHANNEL_PROPERTY it should be pointing to a SVRCONN channel.
Two things to note:
You should not use the predefined SYSTEM.* channels for this purpose (for example SYSTEM.DEF.SVRCONN), you should define a new channel for your application to use. The default channels are meant to hold parameters that you want to be the defaults when creating a new channel of the same type.
MQ v7.1 and later come with a few CHLAUTH rules enabled by default which will block access to the SYSTEM.* channels.
If you want to define a SVRCONN channel using the command line program runmqsc on Windows run the following on a CMD prompt:
echo DEFINE CHL(TEST_QM_CHANNEL1) CHLTYPE(SVRCONN)|runmqsc TEST_QM
Few more details about Channel Tables:
Prior to MQ v8 the only supported method to generate a Channel Table was by defining CLNTCONN channels on a queue manager which creates a file called AMQCLCHL.TAB under the queue manager name folder in a directory called #ipcc. The reason a queue manager comes with a channel called SYSTEM.DEF.CLNTCONNis to provide the default values when you create a new CLNTCONN channel. With v8 and later you can create the channel table using only the runmqsc -n mode, this will directly edit the channel table vs needing to create a CLNTCONN channel on a queue manager. The MQ Client for v8 and later now comes with a client version of runmqsc that can be used to create and alter channel tables.
An application can point to the channel table file in a few different ways, a common way is by setting two environment variables (MQCHLLIB and MQCHLTAB). The app then does not specify channel name, host name, etc in the program, it only needs to specify the name of the queue manager to connect to.
The order and where MQ looks for connection information is documented at the IBM v7.5 (or later) Knowledge Center page "Connecting IBM WebSphere MQ MQI client applications to queue managers". Note this link is for MQI clients, but the same basic order applies to .NET clients as well.

localhost
Try using 127.0.0.1 rather than localhost.
"rx" and "swift_test_tx"
Since you are new to MQ, it is time for you to read up on MQ Best Practices. One item is that it is NOT a good idea to use lowercase characters for MQ objects names. i.e. queues, channels, etc... MQ will always fold to uppercase any names that are not in quotes. So, it is just better to uppercase the names to begin with (less problems in the future).
Next, did you open port 1414 in your firewall? If not, then open the port for both TCP & UDP.

SSIS - C# : script is only working if I put breakpoint (debugging mode) in it

my script is only working (files are being moved, no error) if I insert breakpoint on it.
this is a script to move files to another folder after ETL jobs are done.
the source files is .xls (excel file 2003) and it loops through the file and worksheet of each file.
the files are still being used somehow, after the ETL jobs are done, I still cannot move the file manually.
I dont find any problem if I "copy" the file instead "move".
but for this task, I need to "move" the files after the ETL jobs are done.
I have tried to use "file system task" as well. it's still not working, and the error shows the files are still being used by another progress.
anyone ever has same problem ? or anyone have idea to "release" the excel file after ETL jobs are done ?
Thanks for any help

Web authentication issue using Script Task in SSIS

In the Connection Manager Editor I have listed the URL address and User Name and Passwords and the Test Connection Succeeded. So I am not sure what the problem is. Any help is appreciated.

Send Email (with Attachments) from .Net App without opening Desktop Mail Software or Browser?

I am writing a WPF (C#) application which takes feedback from user and send them through e-mail.
I want my program to send this mail to a fixed address without using any Desktop Mail Software (Outlook Express or Microsoft Outlook or Windows Mail or any other) & without opening any browser window.
In fact i want to send them undetected. That means user should not know about sending mails. (This is an optional requirement which can be ignored).
Anybody tell me how to do this. Thanks in advance.

As an alternative to the standard System.Net.Mail.SmtpClient class provided by the framework, you could use something like DnSmtp. It allows your application to send emails directly without having to configure an SMTP server (it embeds all of the SMTP server 'magic'). If this really needs to run invisibly (assuming also without user configuration or having to hard code values) then this could be a worthwhile option.

You should definitely try using
using System.Net.Mail;
This is a method you can use to do this:
/// <summary>
/// Send an Email
/// </summary>
/// <param name="host">Example: smtp.gmail.com</param>
/// <param name="port">Port to send email</param>
/// <param name="from">Example: Email#gmail.com</param>
/// <param name="password">Password</param>
/// <param name="toList">List of people to send to</param>
/// <param name="subject">Subject of email</param>
/// <param name="messsage">Meddage of emial</param>
/// <param name="deliveryMethod">Deliever type</param>
/// <param name="isHtml">Is email HTML</param>
/// <param name="useSSL">Is email SSL</param>
/// <param name="ccList">List of people to cc</param>
/// <param name="atachmentList">List of attachment files</param>
public void SendMessage(string host, int port, string from, string password, List<string> toList, string subject, string messsage,
SmtpDeliveryMethod deliveryMethod, bool isHtml, bool useSSL, List<string> ccList, List<string> atachmentList)
{
try
{
SmtpClient smtpClient = new SmtpClient(host);
smtpClient.DeliveryMethod = deliveryMethod;
smtpClient.Port = port;
smtpClient.EnableSsl = useSSL;
if (!string.IsNullOrEmpty(password))
smtpClient.Credentials = new NetworkCredential(from, password);
MailMessage mailMessage = new MailMessage();
mailMessage.From = new MailAddress(from);
mailMessage.Subject = subject;
mailMessage.IsBodyHtml = isHtml;
mailMessage.Body = messsage;
if (toList != null)
{
for (int i = 0; i < toList.Count; i++)
{
if (!string.IsNullOrEmpty(toList[i]))
mailMessage.To.Add(toList[i]);
}
}
if (ccList != null)
{
for (int i = 0; i < ccList.Count; i++)
{
if (!string.IsNullOrEmpty(ccList[i]))
mailMessage.CC.Add(ccList[i]);
}
}
if (atachmentList != null)
{
for (int i = 0; i < atachmentList.Count; i++)
{
if (!string.IsNullOrEmpty(atachmentList[i]))
mailMessage.Attachments.Add(new Attachment(atachmentList[i]));
}
}
try
{
smtpClient.Send(mailMessage);
}
catch
{
}
}
catch
{
}
}
I just through a try-catch around everything and did minimal error checking. Hovere, this is the solution you are looking form I hope.

You can use the System.Net.Mail namespace.
The SmtpClient topic in MSDN has a good example of how to do this.
This will require you to embed an SMTP server name or address in your application and this email sending could easily be blocked by corporate or ISP policies (i.e. some ISPs only allow requests to their specific SMTP servers, in large part to block or control spam).

You can use a library like Chilkat or you can connect to a SMTP server using built in .Net stuff like this using system.net.mail.
If your client is running a anti-virus program this is going to be blocked, but there are ways around that if you google.

If you are sending your email through an Exchange 2010 server, then you have another option, in Exchange 2010, it provide a web service, which will provide you the full control of the mailbox.
You can download the SDK from Exchange server SDK
