Unable to read data from an excel document of 365*24 values ( all rounded to 4 decimal points)

I have an excel sheet containing data of hourly loads in MW( rounded to 4 decimals) of one year. So, I have 365*24 values that I want to import to Labview using Read from spreadsheet.vi. However what i get in the output array is 0's and randomly some unit values at very few places. I have checked the array size of the output array and it shows different array sizes for different yearly data.
I am attaching the four excel spreadsheets .
Plz help me with the issue I am facing.

If you are using LabVIEW 2014, it includes the Report Generation Toolkit (which is also available as an add-on in earlier LabVIEW Versions). This can read native Excel files, including .xlsx. With a few functions (3 or 4, I think), you should be able to get the entire Table into a 2D array.

TcpListener not working on Azure: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host

Hi Everybody,
i'm playing a little bit with Windows Azure and I'm blocked with a really simple issue (or maybe not).
I've created a Cloud Service containing one simple Worker Role. I've configured an EndPoint in the WorkerRole configuration, which allows Input connections via tcp on port 10100.
Here the ServiceDefinition.csdef file content:
<?xml version="1.0" encoding="utf-8"?>
<ServiceDefinition name="EmacCloudService" xmlns="http://schemas.microsoft.com/ServiceHosting/2008/10/ServiceDefinition" schemaVersion="2014-01.2.3">
<WorkerRole name="TcpListenerWorkerRole" vmsize="Small">
<Imports>
<Import moduleName="Diagnostics" />
<Import moduleName="RemoteAccess" />
<Import moduleName="RemoteForwarder" />
</Imports>
<Endpoints>
<InputEndpoint name="Endpoint1" protocol="tcp" port="10100" />
</Endpoints>
</WorkerRole>
</ServiceDefinition>
This WorkerRole is just creating a TcpListener object listening to the configured port (using the RoleEnvironment instance) and waits for an incoming connection. It receives a message and returns a hardcoded message (see code snippet below).
namespace TcpListenerWorkerRole
using System;
using System.Net;
using Microsoft.WindowsAzure.ServiceRuntime;
using System.Net.Sockets;
using System.Text;
using Roche.Emac.Infrastructure;

public class WorkerRole : RoleEntryPoint

TcpListener listener = null;

listener = new TcpListener(RoleEnvironment.CurrentRoleInstance.InstanceEndpoints["Endpoint1"].IPEndpoint);
listener.ExclusiveAddressUse = false;
listener.Start();
LoggingProvider.Logger.Info(string.Format("TcpListener started at '{0}:{1}'", RoleEnvironment.CurrentRoleInstance.InstanceEndpoints["Endpoint1"].IPEndpoint.Address, RoleEnvironment.CurrentRoleInstance.InstanceEndpoints["Endpoint1"].IPEndpoint.Port));

StreamReader reader = new StreamReader(networkStream);

writer.AutoFlush = true;

// If a configuration setting is changing
LoggingProvider.Logger.Info("RoleEnvironment is changing....");
if (e.Changes.Any(change => change is RoleEnvironmentConfigurationSettingChange))
// Set e.Cancel to true to restart this role instance
e.Cancel = true;
As you can see, nothing special is being done. I've used the RoleEnvironment.CurrentRoleInstance.InstanceEndpoints to retrieve the current IPEndpoint.
Running the Cloud Service in the Windows Azure Compute Emulator everything works fine, but when I deploy it in Azure, then I receive the following Exception:

I've already tried to configure an internal port in the ServiceDefinition.csdef file, but I get the same exception there.
As you can see, the client can connect to the service (the log shows the message: Client connected with the address) but when it tries to read the bytes from the stream, it throws the exception.
For me it seems like Azure is preventing the retrieval of the message. I've tried to disable the Firewall in the VM in Azure and the same continues happening.
I'm using Windows Azure SDK 2.3
Any help will be very very welcome!
Thanks in advance!

hi Javier,
I changed your code like this:
private AutoResetEvent connectionWaitHandle = new AutoResetEvent(false);
public override void Run()
TcpListener listener = null;
try
listener = new TcpListener(
RoleEnvironment.CurrentRoleInstance.InstanceEndpoints["Endpoint"].IPEndpoint);
listener.ExclusiveAddressUse = false;
listener.Start();
catch (SocketException se)
return;
while (true)
IAsyncResult result = listener.BeginAcceptTcpClient(HandleAsyncConnection, listener);
connectionWaitHandle.WaitOne();
The HandleAsync method is your "While (true)" code:
private void HandleAsyncConnection(IAsyncResult result)
TcpListener listener = (TcpListener)result.AsyncState;
TcpClient client = listener.EndAcceptTcpClient(result);
connectionWaitHandle.Set();
NetworkStream netStream = client.GetStream();
StreamReader reader = new StreamReader(netStream);
StreamWriter writer = new StreamWriter(netStream);
writer.AutoFlush = true;
string input = string.Empty;
try
char[] receivedChars = new char[client.ReceiveBufferSize];
// LoggingProvider.Logger.Info("Buffer size: " + client.ReceiveBufferSize);
int readedChars = reader.Read(receivedChars, 0, client.ReceiveBufferSize);
char[] validChars = new char[readedChars];
Array.ConstrainedCopy(receivedChars, 0, validChars, 0, readedChars);
input = new string(validChars);
// LoggingProvider.Logger.Info("This is what the host sent to you: " + input + ". Readed chars=" + readedChars);
try
string orderResultFormat = Encoding.ASCII.GetString(Encoding.ASCII.GetBytes("\xB")) + @"MSH|^~\&|Instrument|Laboratory|LIS|LIS Facility|20120427123212+0100||ORL^O34^ORL_O34| 11|P|2.5.1||||||UNICODE UTF-8|||LAB-28^IHE" + Environment.NewLine + "MSA|AA|10" + Environment.NewLine + @"PID|||patientId||""""||19700101|M" + Environment.NewLine + "SPM|1|sampleId&ROCHE||ORH^^HL70487|||||||P^^HL70369" + Environment.NewLine + "SAC|||sampleId" + Environment.NewLine + "ORC|OK|orderId|||SC||||20120427123212" + Encoding.ASCII.GetString(Encoding.ASCII.GetBytes("\x1c\x0d"));
writer.Write(orderResultFormat);
catch (Exception e)
// LoggingProvider.Logger.Exception("Unexpected exception while writting the response", e);
client.Close();
catch (Exception ex)
//LoggingProvider.Logger.Exception("Unexpected exception while Reading the request", ex);
client.Close();
Please try it. For this error message, I suggest you could refer to this thread (http://stackoverflow.com/questions/6173763/using-windows-azure-to-use-as-a-tcp-server

Reading data from an excel file

Hi,
I want to read data from the excel file and display it in
jsp page. Iam getting the following error:
[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection con =
DriverManager.getConnection("jdbc:odbc:mydsn","","");
Statement st = con.createStatement();
ResultSet rs = st.executeQuery("select * from [holidays$]");
Here i have created the dsn with the name "mydsn". I have the
following data in the mydsn.dsn file:
[ODBC]
DRIVER=Microsoft Excel Driver (*.xls)
UID=admin
UserCommitSync=Yes
Threads=3
SafeTransactions=0
ReadOnly=1
PageTimeout=5
MaxScanRows=8
MaxBufferSize=2048

DriverId=790
DefaultDir=D:\WorkSpace\Projects\VINET\devl\webroot\jsp
DBQ=D:\WorkSpace\Projects\VINET\devl\webroot\jsp\list_of_holidays_2003.xls
thanks in advance
phani.

You might want to look at the POI project (an open source Jakarta sub-project) that allows you to create/modify/read excel files via Java code. That might be more flexible and easier than what you're currently trying to do.

Can you help me with this problem

More suggestions.
1. If you align naming conventions between data and your application - reading data could be practically a one-liner.
If you write pafh["id_" + i] (with small case i) instead of pafh["Id_" + i] (with capital case I) the function can be just:
function onLoaded(e:Event):void
          for (var prop:String in e.target.data)
                    pafh[prop] = e.target.data[prop].split(",");
          play();
2. If changing conventions is not feasible, here is another thing you can do:
function onLoaded(e:Event):void
          for (var prop:String in e.target.data)
                    pafh[prop.replace(/^\w/, String(prop.match(/^\w/)).toUpperCase())] = e.target.data[prop].split(",");
          play();

Unable to read data from the SAP marketplace

Hi All,
    These days, certain packages in my download basketball cannot be downloaded, while others can be downloaded normally.
     After serveral redirecting, the SAP download manager keeps informing me that "Unable to read data from the SAP marketplace, check your settings and try again".
     Anyone knows how to solve it?
Thanks,
Yining

Hi Yining,
You user on SAP MarketPlace is locked.
You have to unlock it but I do not know the way.
Check in user data maintenance on SAP MarketPlace who is your responsible and perhaps he wwill be able to solve to unlock our user.

Unable to read data from the SAP Service Marketplace issue

Good morning, experts.
I´ve just installed the SAP Download Manager, but I can´t get connected to Marketplace.
First I tried downloading a file I could see in my Basket Download. Then I deleted it from the basket so I could test only the connection. In both situations I got the same error message: "Unable to read data from the SAP Service Marketplace (...)".
It is probably due to wrong settings, but I can´t figure it out. My settings are:
Address: https://websmp205.sap-ag.de/
User name: S0005951541
Password: (my password)
Proxy (my proxy settings)
Any ideas?

Thanks for your answer.
I can see my download basket online. I realize I didn´t delete the items so I could test purely the connection. I am going to do it again.
I found out I dind´t have permission to download those items, and with the right permission I could download them directly online.
As long as I have more information I am going to repost this issue on a new forum.
Thanks.

But i am getting error at "binary" in String mimeType = binary.getMimeType().getFileExtension();
and ByteArrayInputStream bais = new ByteArrayInputStream(element.getFileResource()); by saying that there is no constructor of
ByteArrayInputStream with Resource as parameter.
Please let me know what might be the issue so that i can solve this.
Thanks and regards,
Chandrashekar.

Hi,
Replace the following code
ByteArrayInputStream bais = new ByteArrayInputStream(element.getFileResource());*
with
IWDResource resource = element.getFileResource();
       InputStream inputStream = resource.read(false);
       ByteArrayInputStream bais = new ByteArrayInputStream(inputStream);

Unable to read data from Analog Devices 6b11 module - error code 1240

Hi everyone,
I'm trying to read data from a thermocouple with an AD 6B11 module in an AD 6BP16-1 backplane using RS232 serial. I've been following this guide:
http://digital.ni.com/public.nsf/allkb/8C77E5E52B4A27968625611600559421
Everything seems to work out well until step 13, where I call the "AD6B Input Module - Read Data.VI". I get an error code 1240 stating something like "invalid parameter or unable to read instrument".
Has anyone got any experience with this error or suggestions to fixing it?
Thanks in advance!

That user guide is 20+ years old. The serial functions from that day used 0 for com 1, 1 for com 2, etc. Make sure you have the correct one selected. Please provide the exact error message instead of 'something like'.

Table unable to read data from CSV file

Dear All,
I have created a table which have to read data from external CSV file. The table is giving error if the file is not there at the specified location,but when i put the file at that location there is no error but no rows are returned.
Please suggest what should i do???
Thanks in advance.

No version.
No operating system information.
No DDL.
No help is possible.
I want to drive home the point here to the many people that write posts similar to yours.
"My car won't start please tell me why" is insuffiicent information. Perhaps it is out of gas. Perhaps the battery is dead. Perhaps you didn't turn the key in the ignition.

How to read data from many excel files

I'm aquiring data continusly from several sensors, and every days file name are changed. Data are saved on xls files.
Now, I'd like to read every data from this files and put them in a waveform. How can I concatenate all files and read the values?

You probably do not want to use a traditional waveform. LabVIEW has a Waveform Chart which inputs one point at a time. Waveform Graph inputs an array.
I suspect that the data is stored in an array. You need to read the arrays in and build them into larger arrays. If your right click on the build array vi, you can select concantenate which will append one array to the end of the other. When you have built your giant array, just feed it to a waveform graph.
If you need to see some example code, go to the advanced search page. It is at www.ni.com >> support >> advanced search (it is at the botton--click on the words). Enter excel read in the all the words field and search just the example programs. There were for hits.
