I can save shared data (like dsn) in application.cfm so all
the cfm file can read it.
But how to share data in cfc files like application.cfm. I
hear application.cfc,may I use it share data in cfc files?
Do you think if it is ok that application.cfm and

Don't use both. Things like a dsn are best defined in the
onApplicationStart method of an application.cfc.

Datalogging and Supervisory Control : how to share data among LabVIEW applications on the same network?

I'm new to DSC. Is there an example program or article about how to share data (live data and data saved after running a program) among LabVIEW (using DSC) that is very basic? I would like to share live data and test reult data (eg. excel) among computers on the same network (may be LAN). Does sharing data over a network by using DSC makes whole system (all computers) down when one computer is locked up?

Hi,
The easiest way to network DSC data is using "network tags". The way you do it is by simply configuring the server PC as you normally would do for a local application.
Then from a remote compute, which we can call a client computer you can go to Tag Configuration Editor and option "File >> Import Network Tags.."
In the window that opens up you can hit the browse buttom and navigate to your server computer, select the .scf file you want to have and hit the buttom import.
Save the "client .scf" file locally and now you have in the client the same configuration you have in the server and your data is networked, from there on is just a matter of manipulating the data.
I hope it helps

How to read data from a file that was formatted by excel?

How to output data to a file in SCC-SG04?

I am using SCC-2345 with SCC-SG04 connected to NI-6221 in Windows 2000 in VC6.
How to output data to a file like data1.dat in VC6 or in Labwindows/CVI?

Hello mwibm,
If you just want to do file input/output in LabWindows/CVI, I would take a look at the Formatting and I/O CVI library or the ANSI File I/O functions. For example, if you just want to write an array of data to a file, I would look at the ArrayToFile function or the fwrite/fputs/fprintf ANSI C functions included in stdio.h. The ANSI C functions will also work in Visual Studio. More information on the LabWindows/CVI File I/O functions can be found in CVI help, and more information on ANSI C functions can be found in CVI Help and online at various websites.
Maybe you could further clarify what problems you are having and what kind of data you want to write to a file.
Thanks.

How do share a very large file?

How do share a very large file?

Do you want to send a GarageBand project or the bounced audio file? To send an audio file is not critical, but if you want to send the project use "File > Compress" to create a .zip file of the project before you send it.
If you have a Dropbox account, I'd simply copy the file into the Dropbox "public" folder and mail the link. Right-click the file in the Dropbox, then choose Dropbox > Copy Public Link. This copies an Internet link to your file that you can paste anywhere: emails, instant messages, blogs, etc.
2 GB on Dropbox are free. https://www.dropbox.com/help/category/Sharing

How to insert data from *.dmp file to oracle 11g using Oracle SQL Develope

hi
i backup my database using PL/SQL developer and made *.dmp file
how to insert data from *.dmp file to oracle 11g using Oracle SQL Developer 2.1.1.64
and how to make *.dmp file from sql*plus ?
thanks in advance

Pl/Sql developer has a config window, there you choose the exec to do the import/export.
Find it and his home version, it may be exp or expdp, the home version is the version of the client where the exp executable is.
Then use the same version of imp or impdp to execute the import, you do not need to use Oracle SQL Developer 2.1.1.64. If you want to use it, you must have the same version in the oracle home that exp/imp of sql developer use.

How to share data between applications.

I'm trying to share data between LabVIEW v6.0 and another program (16 bit), both running on Windows95. At first DLL's seemed to be the answer but I would need to call 16 bit DLL's which I understand can be a problem. With my limited knowledge of C++ I've written a program (Borland C++4.2) which can access the data I need and save it to a file, this is then repeatedly read by LabVIEW, crude but it works. When I add code to do the same the other way I get occasional file sharing errors. I can't get either LabVIEW or C++ to trap these errors. As an alternative I thought I could write and read to a reserved portion of memory (less than 1K should be enough) using in port and out port. Is this viable, and if so how do I
reserve the memory in Windows 95 so that LabVIEW & my C++ program can access it?
Any suggestions?

May be TCP/IP or UDP interprocess communication will do? It shouldn't be
a problem via localhost. You can try separate VI server to handle
communication task from your vi with C++ socket.

How to delete data from a file using IO package

Hi All,
i am trying to remove some content of the file.
this content is not at starting of file not even at end of file.
can anybody tell me how can i delete number of lines from file using IO package.

iam having some data in text file .ex:in flowrist.txt
12/5/07,500,300,6000 like many set of datas are
there.In these if i want to delete the data based on
the date which i specified.How to do this specific
deletion?You need to open a stream to read in the file and then use the indexOf method provided in the Sting class to check if the line contains the date or whatever String you are looking for, if so then skip that line and store or re-write the lines you wish to keep, as well as some extra lines you may wish to add.
Take a look below at this example found on Google.
http://www.java-tips.org/java-se-tips/java.io/how-to-read-file-in-java.html
The above read a file line by line and prints it to console. You should be able to modify this, instead of using System.out to print the line you should use index of to check the lines for a date/String. Index of return -1 if the String you specify is not in the line you parse.

How to read data from multiple files and append in columns in one file

Hi Guys,
I have a problem in appending data from files in different columns. I have attachement has file A and B which I am reading and not able to get data as in file Result.txt. Please comment on how can I do this
Solved!

B.txt.txt ‏1 KB

You cannot append columns to an existing file. Since the data is arrange line-by-line as one long linear string in the file, you can only append rows. A new row needs to be interlaced into the original file, shifting everything else. If you want to append rows, you need to build the entire output structure in memory and then write all at once.
(I also don't think you need to set the file positions, it will be remembered from the last write operation.)
Unless the files are gigantic, here's what I would do:
(Also note that some of your rows have an extra tab at the end. If this is normal, you need a little bit more code to strop out empty columns. I include cleaned up files in the attachment. I also would not call them A.txt.txt etc. A plain A.txt is probably sufficient.)
EDIT: It seems Dennis's solution is similar )

Looks like you're creating a new file (which overwrites the old one) every time. You need to open the file first and then append to it.

How to store data in a file without using DB

Hi all
I want to develop a small application that could contain at most 10000 records, so if it is possible I want to store the data in a file, therefore the installation of the application can be simplified and the users don't need to add a ODBC dataSource in the control panel before running the program.
If the above is not possible. Does anyone know how to use Java to programmatically add a ODBC dataSrouce in the control panel in the Windows Platform?
Thank you very much !
Kind Regards
Edmond

1 ) Save the records into a vector and write it to a file. You will have to load all the records when you read the file though.
2 ) Use a dsn-less connection. You do not need to have a dsn set up and you can access a file using the bridge driver:
url = "jdbc:odbc:Driver={Microsoft Excel Driver (*.xls)};DBQ="+file.getPath();
               //Obtain the driver for the
               Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
               //Create the connection
               con = DriverManager.getConnection(url, "", "");
               //Ensure that the connection allows two way commands
               if (con.isReadOnly()) con.setReadOnly(false);
               //Create the statement to be executed
               stmt = con.createStatement();
     //execute the select statement
               ResultSet rs = stmt.executeQuery("SELECT * FROM \"Sheet1$\"");
This should work, let me know if it dwosnt

How to extract data from .xltm file in a (dataset, datatable or a list) using wpf c#

Hi all,
As we can get data from .xls, .xlsx file in a dataset. Now i want to read all the entire data from .xltm file.
I also want to get all sheets name from .xltm file. I am using .Net framework 4.5, Visual studio 2012.
Please help me. I am unable to extract it. It is urgent.

Hello Kalpna Bindal,
I just investigate this issue and use the following way but it does work:
private void Button_Click(object sender, RoutedEventArgs e)
// initialize connection
OleDbConnection con = new OleDbConnection();
con.ConnectionString =
"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=D:\\Fruits1.xltm;Extended Properties=\"Excel 12.0 Xml;HDR=YES;\"";
//pass query to Insert values into Excel
OleDbCommand cmd = new OleDbCommand();
cmd.CommandText = "insert into [Sheet1$] values('')";
cmd.Connection = con;
// EXECUTE QUERY
con.Open();
cmd.ExecuteNonQuery();
con.Close();
I then did a research about this issue and find the following case:
http://stackoverflow.com/questions/22225017/reading-excel-xltm-files-programmatically
To test whether it is possible I use the following code in WPF:
Microsoft.Office.Interop.Excel.Application xltmApp = new Microsoft.Office.Interop.Excel.Application();
xltmApp.Visible = false;
xltmApp.ScreenUpdating = false;
Workbook xltmBook = xltmApp.Workbooks.Open(@"D:\Fruits1.xltm");
Worksheet xlworksheet = xltmBook.Worksheets.get_Item(1);
for (int i = 1; i <= 1; i++)
for(int j=1;j<=1;j++)
string str = (string)(xlworksheet.UsedRange.Cells[i, j] as Microsoft.Office.Interop.Excel.Range).Value;
MessageBox.Show(str);
The result is that I can read this .xltm file and read the firstline without problem.
I would think you can also use this way to work with your .xltm file and output it to your application.
For more details about how to fill to your WPF, common wpf and excel thread will be helpful:

How to get data from a file?

Hello everyone, i'm new to this forum and to java too. Ok, so here is what i want to do:
I want to get data from a file containing words and numbers and store them into variables that i will use them after to insert into a database table. For example i have a file called employees.txt in this form:
eid ename zipcode Hire_date
1000 "Jones" 67226 "12-DEC-95"
In C++ i declare variables for each data and store them, for example in this case:
ifstream in("somefile");
string name, hdate;
int eid, zip;
in >> eid >> ename >> zip >> hdate;
So i want to do the same thing in JAVA but i can't make it work. So, i would appreciate if someone could give me a simple example how to do it. Thank you.
