Beginner - How to log using multiple files

I am in trouble when I try to record the produced data into multiple files. There is a Rec button that is used to start to log the data that is produced by the system.
As you can see in the attached image.
The problem is that the user can stop the data logger and then start it again. And so, I need to create a new file. I configured the "write to measurement file" to save data into multiple files, but, it is appending the data into the file created before.
How can I solve this?
Thank you in advance.

You could do something like this.
This creating a filename based on the hour and minute of the day then passing that as a parameter into the Write Measurement File function. Watch out its possible to get duplicate filenames with this method. Consider adding date elements to make the filename more unique.

Sliding Window Table Partitioning Problems with RANGE RIGHT, SPLIT, MERGE using Multiple File Groups

There is misleading information in two system views (sys.data_spaces & sys.destination_data_spaces) about the physical location of data after a partitioning MERGE and before an INDEX REBUILD operation on a partitioned table. In SQL Server 2012 SP1 CU6,
the script below (SQLCMD mode, set DataDrive & LogDrive variables for the runtime environment) will create a test database with file groups and files to support a partitioned table. The partition function and scheme spread the test data across
4 files groups, an empty partition, file group and file are maintained at the start and end of the range. A problem occurs after the SWITCH and MERGE RANGE operations, the views sys.data_spaces & sys.destination_data_spaces show the logical, not the physical,
location of data.

The table below shows the results of the ‘Confirm Table Partitioning’ query, before and after the MERGE.
The T-SQL code below illustrates the problem.
-- PartitionLab_RangeRight
USE workspace;
DROP TABLE dbo.TestTableOut;
USE master;
ALTER DATABASE workspace
REMOVE FILE TestTable_f3 ;
-- ERROR
--Msg 5042, Level 16, State 1, Line 1
--The file 'TestTable_f3 ' cannot be removed because it is not empty.
ALTER DATABASE workspace
REMOVE FILE TestTable_f2 ;
-- Works surprisingly!!
use workspace;
ALTER INDEX [PK_TestTable] ON [dbo].[TestTable] REBUILD PARTITION = 2;
--Msg 622, Level 16, State 3, Line 2
--The filegroup "TestTable_fg2" has no files assigned to it. Tables, indexes, text columns, ntext columns, and image columns cannot be populated on this filegroup until a file is added.
--The statement has been terminated.
If you run ALTER INDEX REBUILD before trying to remove files from File Group 3, it works. Rerun the database setup script then the code below.
-- RANGE RIGHT
-- Rerun PartitionLabSetup_RangeRight.sql before the code below
USE workspace;
DROP TABLE dbo.TestTableOut;
ALTER INDEX [PK_TestTable] ON [dbo].[TestTable] REBUILD PARTITION = 2;
USE master;
ALTER DATABASE workspace
REMOVE FILE TestTable_f3;
-- Works as expected!!
The file in File Group 2 appears to contain data but it can be dropped. Although the system views are reporting the data in File Group 2, it still physically resides in File Group 3 and isn’t moved until the index is rebuilt. The RANGE RIGHT function means
the left file group (File Group 2) is retained when splitting ranges.
RANGE LEFT would have retained the data in File Group 3 where it already resided, no INDEX REBUILD is necessary to effectively complete the MERGE operation. The script below implements the same partitioning strategy (data distribution between partitions)
on the test table but uses different boundary definitions and RANGE LEFT.

The table below shows the results of the ‘Confirm Table Partitioning’ query, before and after the MERGE.
The data in the File and File Group to be dropped (File Group 2) has already been switched out; File Group 3 contains the data so no index rebuild is needed to move data and complete the MERGE.
RANGE RIGHT would not be a problem in a ‘Sliding Window’ if the same file group is used for all partitions, when they are created and dropped it introduces a dependency on full index rebuilds. Larger tables are typically partitioned and a full index rebuild
might be an expensive operation. I’m not sure how a RANGE RIGHT partitioning strategy could be implemented, with an ascending partitioning key, using multiple file groups without having to move data. Using a single file group (multiple files) for all partitions
within a table would avoid physically moving data between file groups; no index rebuild would be necessary to complete a MERGE and system views would accurately reflect the physical location of data.
If a RANGE RIGHT partition function is used, the data is physically in the wrong file group after the MERGE assuming a typical ascending partitioning key, and the 'Data Spaces' system views might be misleading. Thanks to Manuj and Chris for a lot of help
investigating this.
NOTE 10/03/2014 - The solution
The solution is so easy it's embarrassing, I was using the wrong boundary points for the MERGE (both RANGE LEFT & RANGE RIGHT) to get rid of historic data.
-- Wrong Boundary Point Range Right
--ALTER PARTITION FUNCTION $(TableName)_func()
--MERGE RANGE (15);
-- Wrong Boundary Point Range Left
--ALTER PARTITION FUNCTION $(TableName)_func()
--MERGE RANGE (14);
-- Correct Boundary Pounts for MERGE
ALTER PARTITION FUNCTION $(TableName)_func()
MERGE RANGE (0); -- or -1 for RANGE LEFT
The empty, switched out partition (on File Group 2) is then MERGED with the empty partition maintained at the start of the range and no data movement is necessary. I retract the suggestion that a problem exists with RANGE RIGHT Sliding Windows using multiple
file groups and apologize :-)

How can I convert multiple files at one time and not one at a time

How can I convert multiple files at one time and not one at a time

Hi Plissey1950,
Sorry for the lengthy delay to a response. Are you trying to convert multiple files to individual PDF files at the same time? (not combine them). If so, you'll need to use Adobe Acrobat for this function. The CreatePDF service does not have the ability to convert multiple files to multiple individual PDF files.
Thanks,
David

How do I process multiple files and turn them from raw to jpeg

How do I process multiple files and turn them from raw to jpeg. Ive tried and it seems to go through the files but doesnt seem to process them or store them in the selected folder

Yes that was the first thing I did. Then I used the process multiple files and selected a new folder to put them in and selected use open files and selected to turn them into jpeg. The images flash on the screen like they are being processed, but the folder never appears in library. Is it possible because there are a couple 16 bit files open that this corrupts the task. Do I need to create the folder first. Will elements not create the folder on its own.
Thanks Vince

How do I select multiple files under "Get File Info"and lock or unlock all?

How do I select multiple files under "Get File Info"and lock or unlock them all? It seems to do it automatically when I have 10 or more selected. But how do I lock or unlock 5 or 6 files in one swoop? Thanks

Select the desired files then press OPTION and select Show Inspector from the Finder's File menu.

How to tell if multiple files are selected when they are opened in windows

Hello, can someone help me, my question is how to tell if multiple file selections were made when they were opened (right-click->open). Through modifying the registry I already have my Java program start up when a file with specific extension is double-clicked.
The problem is when multiple files are opened at the same time, an instance of java program is created and run for each of the selected files. Ideally I would like it so that only one instance of java program is run, regardless of the number of selections.
When you try it with Microsoft media player or winamp for example, it seems that only one process is created and run (I don't see many processes spawning when I watch it using task manager). Maybe this is more of Windows issue rather than Java programming issue. Any help is appreciated.

If anybody wants to know, this can be solved by either 1) using DDE 2) using DropTarget (from Windows) 3) make a light-weight EXE dispatcher (eg. in C), and use file to have IPC between the dispatcher (which gets the filepath for each of the selections) and the java program. There can be other methods of course. Using the second option is the simplest but it requires WinXP and higher. I implemented it using option 3.. the downside of this is there's a warning message pop up when trying to open many (>20?) files at the same time by Windows. However, option 1 'seems' to have the same limitation. Having a java program created each time for each of the selections seems to be too slow, for viable option.

Multiple MailAttachment to File - How to store as multiple files ?

Hi Friends ,
 Can you please tell me How to Store as Multiple files which i read as attachements from Mail Sender Adapter .
 In My scenario i can able to bring the Multiple attachement in the Paylod using PaylodSwapBean . I wan to store these attachements to a file system. ie. Whatever attachements i am reading i have to store in a file .
 For eg., In my scenario i have designed the Data Type as DT_Test--> Row --- > Details .
 Details can able to hold each line of Each File . One file contains multiple Line data .
 If i use Message Transform Bean , first attachement only getting Tranformed rest of them as it is . Not getting tranformed to required format.
 Please give some suggestions !
Regards .,

How can I upload multiple files or whole folder structures in one go to the Cloud?

How can I upload multiple files or whole folder structures to the Cloud in one go? Uploading lots of files singularly does not help my workflow.
All help is much appreciated.
Paul.

Hi,
Uploading multiple files is browser specific.
Internet explorer won't allow to select and upload multiple files on the cloud.
If you want to upload multiple files then you have to login to Cretaive cloud using Firefox or Chrome web browser, then you can select multiple files in the Browse window to upload.
You can't upload folders directly.

Super Basic, How do I select multiple files?

Super Basic, How do I select multiple files? I can click on one, but I want to select an entire group of files. On a PC I would use the control or shift keys, or just use the mouse to draw a box around them, but nothing seems to work.

It works here using the Shift key (after selecting the first item, hit Shift key while clicking on another). If you display your Finder windows as list or columns, it's extra easy: You click on the first item, then hit Shift and click on the last item - all of them will be selected.

How to check-in multiple files with same name having different revision num

Hi
Can anyone please tell me, how to check-in multiple files with the same name with different revision number using RIDC API.
For eg:
First I will check-in a file(TestFile.txt) into a content server with revision number 1 using RIDC API in ADF application. Then after some time, will modify the same file(TestFile.txt) and check-in again. I tried to check-in same file multiple times, however first time its checking-in correctly into server showing revision as 1, while checking-in same file again, its not giving any errror message, and also its not reflecting in server. Only one file(TestFile.txt) is reflecting in server.
How to implement this functinality using RIDC API? Any suggestions would be helpful.
Regards
Raj

Hi Srinath
Thanks for your response. Its not cloning, its like check-in file first, then check-out the file and do some editing and then again upload the same file with different revision number using RIDC. I got the solution now.

How can I allow multiple file selections ?

I used FileReference's browse function,
But it's only can select one file at the same time.
How can I allow multiple file selections ?
Thanks a lot.

You need a FileReferenceList object instead. See the Help for
FileReferenceList, it has good examples.

How do you select multiple files to drag

How do you select multiple files to drag from one folder to another? Is there a command?

Open the folder which has the contents you want to transfer. Press COMMAND 'A' and then all of the data should be highlited in blue. Drag it to the new folder.
If only certain files are to be transferred, then you have to select them (COMMAND 'A') individually and the drag them as a group to the new location.
Ciao.

How do you select multiple files at one time

How do you select multiple files at one time

Select one, and then either command-click another, or in list/column view, Shift-click the item at the other end of the range you want to select. Alternatively, click on a spot in the screen and drag the cursor until all the files are selected.

How can I use multiple row insert or update into DB in JSP?

Hi all,
pls help for my question.
"How can I use multiple rows insert or update into DB in JSP?"
I mean I will insert or update the multiple records like grid component. All the data I enter will go into the DB.
With thanks,

That isn't true. Different SQL databases have
different capabilities and use different syntax, That's true - every database has its own quirks and extensions. No disagreement there. But they all follow ANSI SQL for CRUD operations. Since the OP said they wanted to do INSERTs and UPDATEs in batches, I assumed that ANSI SQL was sufficient.
I'd argue that it's best to use ANSI SQL as much as possible, especially if you want your JDBC code to be portable between databases.
and there are also a lot of different ways of talking to
SQL databases that are possible in JSP, from using
plain old java.sql.* in scriptlets to using the
jstlsql taglib. I've done maintenance on both, and
they are as different as night and day.Right, because you don't maintain JSP and Java classes the same way. No news there. Both java.sql and JSTL sql taglib are both based on SQL and JDBC. Same difference, except that one uses tags and the other doesn't. Both are Java JDBC code in the end.
Well, sure. As long as you only want to update rows
with the same value in column 2. I had the impression
he wanted to update a whole table. If he only meant
update all rows with the same value in a given column
with the same value, that's trivial. All updates do
that. But as far as I know there's know way to update
more than one row where the values are different.I used this as an example to demonstrate that it's possible to UPDATE more than one row at a time. If I have 1,000 rows, and each one is a separate UPDATE statement that's unique from all the others, I guess I'd have to write 1,000 UPDATE statements. It's possible to have them all either succeed or fail as a single unit of work. I'm pointing out transaction, because they weren't coming up in the discussion.
Unless you're using MySQL, for instance. I only have
experience with MySQL and M$ SQL Server, so I don't
know what PostgreSQL, Oracle, Sybase, DB2 and all the
rest are capable of, but I know for sure that MySQL
can insert multiple rows while SQL Server can't (or at
least I've never seen the syntax for doing it if it
does).Right, but this syntax seems to be specific to MySQL The moment you use it, you're locked into MySQL. There are other ways to accomplish the same thing with ANSI SQL.
Don't assume that all SQL databases are the same.
They're not, and it can really screw you up badly if
you assume you can deploy a project you've developed
with one database in an environment where you have to
use a different one. Even different versions of the
same database can have huge differences. I recommend
you get a copy of the O'Reilly book, SQL in a
Nutshell. It covers the most common DBMSes and does a
good job of pointing out the differences.Yes, I understand that.
It's funny that you're telling me not to assume that all SQL databases are the same. You're the one who's proposing that the OP use a MySQL-specific extension.
I haven't looked at the MySQL docs to find out how the syntax you're suggesting works. What if one value set INSERT succeeds and the next one fails? Does MySQL roll back the successful INSERT? Is the unit of work under the JDBC driver's control with autoCommit?
The OP is free to follow your suggestion. I'm pointing out that there are transactions for units of work and ANSI SQL ways to accomplish the same thing.
