Write to mesaurement file error

Okay, this question has been asked various times with different solutions but nos of those solution seems to help me.
I start the VI, begins recording automatically wihtout any problem, it creates the file and the folder etc... but when I pause the recording and then unpaused it shows the following error and shows no path

this is the block dia.
Like I said, I tried different post it solution and nothing.

Error running exe to write to exel file: Error 7 New file not found

Hello!I have this problem, i've looked everywhere and i still can't solve it. It would be great if anyone can help me.
I built an application that writes an array to a spreadsheet file.
Everything works fine in Labview 7.1 , i can build the exe file, but
when i try to run it it doesn't work (it doesn't do anything although
in Labview works perfecty well)and i have this error:
<<Error 7 occurred at New File; Possible reason(s):
LabVIEW: File not found. The file might have been moved or
deleted, or the file path might be incorrectly formatted for the
operating system. For example, use \ as path separators on Windows, :
on Mac OS, and / on UNIX.>>
I've attached the vi file and the exe file.
Thank you

You've made a very, very common mistake and one discussed in numerous postings. When running in development mode and using the Current VI's Path, the path to a VI would be something like c:\folder\example.vi. When built, it becomes c:\folder\app.exe\example.vi. An extra strip path is required. Look at this, this, and this.

Write-read binary file Error 116

Hi all,
I am saving double, numeric array data into a binary file and then trying to read it back but keep on getting Error 116 (cannot read from binary file).
I have attached screenshots of the way I am writing my data into the binary file and then the way I am trying to read it. Basically my data is chunks of 2D double arrays, coming at a rate of 1hz and this is why I have to use the get and set file size functions prior to saving into the file (i.e. so that each time I can append my file with new data).
I have tried all combinations for the write to binary and read to binary file functions, thus meaning I have tried little, big and native endian options but I keep getting the same error. Also played with the way I append my data, i.e. I have used both the "offset in bytes" and "end of file" options, just in case this made any difference, but again no luck.
Any help would be much much appreciated.
Regards,
Harry

Just as an amendment to my original post, I can succesfully read my data in MATLAB using the standard fread function with double precision. I presume that this means that there is nothing wrong with the way I write the data into the file. However, it would be useful for me to be able to read it directly from Labview without having to build matlab executables etc etc...
cheers again

Attempting to write data to file, but getting error 200279

I am having trouble when writing data to a file. About 10 seconds into the saving process, I get the error 200279. I have done some research on the topic, but am unable to corect my code. I believe I do not want to increase the buffer size, but would rather, I assume, read the data more frequently. The way I save my file is, before running the VI, I assign a location and name of the file (e.g. data.csv). The date and time is appended to the end of the actual file when the I begin to save the data (e.g. data_07-26-13_122615.csv). If the file does not exist, it creates a new file, then appends data to that file after every loop iteration. The reason I did it this way was so I do not have to worry about running out of memory, but apparently my code is flawed.
I will include a copy of the flawed section of my code. Any help would be greatly appreciated.
Thanks.

Your problem is that writing to disk is slow. It is slow enough that it is causing your DAQ buffer to overflow and cause the error and loss of data. What you need to do is implement a Producer/Consumer. This will put the daq and the logging to disk in seperate loops. This will allow the DAQ to run at the speed it needs to keep up with incoming samples and the writing to disk can run at whatever rate it can. You send the DAQ data to the logging loop using a queue.
You might also want to think about changing how you write to the file. That VI is constantly opening and closing the file, which is a very slow process if you are doing it inside of a loop.

Corrupt file error while writting a file in compress mode

Hello,
I have a scenario where i am writting data in a file in appending mode with filter 'compress' addition using open dataset, on Al11 for the first set of records it works fine but if this file is accessed again for writting data in next select statement ( its between select endselect),the file is getting corrupted, if i try to open this file corrupt file error come. can someone help.
Thanks and Regards,
Gunjan

Hi Gunjan,
Unfortunately, you can't do in that way. The behaviour of that OPEN and FILTER 'compress' clause is to create a compacted file, to be read later, but it can be appended... all your writes go to a pipe and when you close the file this is sent to 'compress' program or other filter and than a compacted file is created.
You can't go back and start inserting again after close it.
Follow documentation:
http://help.sap.com/abapdocu_70/en/ABAPOPEN_DATASET_OS_ADDITION.htm
The addition FILTER must not be used together with the addition AT POSITION or for the access type FOR UPDATE.

Labview 9.0: Error 1 occurred at Write To Measurement File

Hi
Our University recently got the latest version of Labview (9.0 32-bit) which I installed today.The labview file I am using (my6008v6.vi) used to work fine with the older version (8.5 i think). My write-to-file VI is enabled at certain time intervals in order to log data. As soon as it is enabled for the second time I get the following error:
Error 1 occurred at Write To Measurement File->Copy of murray6008v6.vi
Possible reason(s):
LabVIEW: An input parameter is invalid. For example if the input is a path, the path might contain a character not allowed by the OS such as ? or @.
=========================
NI-488: Command requires GPIB Controller to be Controller-In-Charge.
I made a simple file (simplew2f.vi) to test this, with a button which I can press to enable/disable the writing of data. I am able to start writing data and then stop writing data but as soon as I try resume the writing the same error occurs.
This confuses me greatly since this wasn't a problem using the old version and my Labview knowledge is minimal. Any help would be appreciated.

So, which VI are you having problems with? Sounds like both...
Okay... - sigh - where to start....
Well.. Let's start with a few comments.
1. Try to stay away from the Express VI. I know the Marketing guys at NI will not like me for saying so, but I am saying so. They are a nice marketing feature that Grumpy Old Men like myself do not like. They make it easy to write quick code.. And I will limit my comments to that. (It's not your fault.. )
2. The wiring on your diagram is not clear or easy to read. Yes, with additional time and double-clicking each wire I can tell where they are going. However, a rule of thumb, alway wire from Left to Right. Never right to left. And do not run the wires under objects, even the ones you are wiring to.
3. simplew2f.vi: You should put a small delay in the While Loop. I ran it three times and it wrote to the files without error. And yes, I used LV2009.
4. my6008v6.vi: Avoid wiring from the top of the While Loop. At frist, it looked like the data was coming out of the While Loop because the wires went to the left side of all the index node of the Index Array function.
You should set your Browse Option for the file path to "Files or Folders" and "New or existing". I did that and I was not getting the error message you described.

Write to text file returns no error even if the underlying file is deleted

Hi,
I'm using a CompactRIO and writing to a text file underneath the C drive.
I'm running into an unexpected situation when I am trying to error check my file handling. I assumed that if the underlying file being written to that was created by open/create/replace vi and written to with the "Write to Text File" vi, would return an error if I delete the file from underneath it in the file system., yet there is no reported error and the function carrys on seemingly successfully writing to a file that has been deleted.
Anyone know why this happens and how to potentiallly remedy?

Ouch, this obviously isn't ideal but is probably down to the filesystem on the CompactRIO.
I would consider putting in a check - doing something like getting the file position from the file might return an error if the file no longer exists.

Load blob to file. error: file write error

Hi,
I used procedure witch load blob to file. It's working at Oracle 10g, but its does't work on oracle 11g. Why?
create or replace PROCEDURE load_blob_to_bfile (p_file_id IN VARCHAR2, p_directory IN VARCHAR2, p_ident in varchar2 default NULL)
IS
v_blob BLOB;
v_start NUMBER := 1;
v_bytelen NUMBER := 2000;
v_len NUMBER;
v_raw RAW (2000);
v_x NUMBER;
v_output UTL_FILE.file_type;
v_file_name VARCHAR2 (200);
BEGIN
-- get length of blob
SELECT DBMS_LOB.getlength (blob_content), filename
INTO v_len, v_file_name
FROM wwv_flow_files
WHERE filename = p_file_id;
-- define output directory
v_output := UTL_FILE.fopen (p_directory, p_ident||'_'||v_file_name, 'wb', 32760);
-- save blob length
v_x := v_len;
-- select blob into variable
SELECT blob_content
INTO v_blob
FROM wwv_flow_files
WHERE filename = p_file_id;
v_start := 1;
WHILE v_start < v_len AND v_bytelen > 0
LOOP
DBMS_LOB.READ (v_blob, v_bytelen, v_start, v_raw);
UTL_FILE.put_raw (v_output, v_raw);
UTL_FILE.fflush (v_output);
/* Text only could be: UTL_RAW.cast_to_varchar2 (v_raw);*/
-- set the start position for the next cut
v_start := v_start + v_bytelen;
-- set the end position if less than 32000 bytes
v_x := v_x - v_bytelen;
IF v_x < 2000
THEN
v_bytelen := v_x;
END IF;
END LOOP;
UTL_FILE.fclose (v_output);
END;
directories is creaited and granted for read and write. It looks like file is created, but application rise the write file error, and files in directory is emty.

So, I'm copying the file in a temp. BLOB with this function:
FUNCTION get_remote_binary_data (p_conn IN OUT NOCOPY UTL_TCP.connection,
p_file IN VARCHAR2)
RETURN BLOB IS
l_conn UTL_TCP.connection;
l_amount PLS_INTEGER;
l_buffer RAW(32767);
l_data BLOB;
BEGIN
DBMS_LOB.createtemporary (lob_loc => l_data,
CACHE => TRUE,
dur => DBMS_LOB.CALL);
l_conn := get_passive(p_conn); //get a passive connection
send_command(p_conn, 'RETR ' || p_file, TRUE); //send Retrieve command to server
BEGIN
LOOP
l_amount := UTL_TCP.read_raw (l_conn, l_buffer, 32767);
DBMS_LOB.writeappend(l_data, l_amount, l_buffer);
END LOOP;
EXCEPTION
WHEN UTL_TCP.END_OF_INPUT THEN
NULL;
WHEN OTHERS THEN
NULL;
END;
UTL_TCP.close_connection(l_conn);
get_reply(p_conn);
RETURN l_data;
END;
Then I'm writing it into a local file:
PROCEDURE put_local_binary_data (p_data IN BLOB,
p_dir IN VARCHAR2,
p_file IN VARCHAR2) IS
l_out_file UTL_FILE.FILE_TYPE;
l_buffer RAW(32767);
l_amount BINARY_INTEGER;
l_pos INTEGER := 1;
l_blob_len INTEGER;
BEGIN
l_blob_len := DBMS_LOB.getlength(p_data);
l_amount := DBMS_LOB.GETCHUNKSIZE(p_data);
IF (l_amount >= 32767) THEN
l_amount := 32767;
END IF;
l_out_file := UTL_FILE.FOPEN(p_dir, p_file, 'w', 32767);
WHILE l_pos < l_blob_len LOOP
DBMS_LOB.READ (p_data, l_amount, l_pos, l_buffer);
UTL_FILE.put_raw(l_out_file, l_buffer, FALSE);
l_pos := l_pos + l_amount;
END LOOP;
UTL_FILE.FCLOSE(l_out_file);
EXCEPTION
WHEN OTHERS THEN
IF UTL_FILE.IS_OPEN(l_out_file) THEN
UTL_FILE.FCLOSE(l_out_file);
END IF;
RAISE;
END;
I've checked the blob before I'we wrote it ito the file (UTL_FILE.put_raw(l_out_file, l_buffer, FALSE)), and it contains no carriage-return.

I've looked into Oracle Database 10g Express Edition (Universal), a .deb file, found no occi.h but did find lots of .so files (linux shared libraries). I'll try and adapt my code and Netbeans/g++ to that and see if it works...
I can't really install it since my 4GB computer is x64 and my i386 "only" has 186RAM... Enterprise Linux Release 5 Media Pack for x86 64 (64 bit) is 5.1GB+updates (~5GB each)... Not gonna waste my time installing that just for a project.
I sense i'm missing something obvious... although there's nothing obvious about *.oracle.com... information company they say? ;)

Write file error 8

Once the file is created subsequent writes show Error code 8 out of the "Write File" VI LV6. (Cannot upgrade the code at this time). I'm using open/create/Replace File VI along with the Write File VI. Creating the file run OK, once I go back and rerun for a write the "Write File" reports Error code 8. How do I fix this issue.... using LV6.

The file created by the open/create/Replace VI attributes are NOT set to READ ONLY. See the pic below. If the LV creates the file it should be able to subsequently write to the same file. Once again this is LV version 6. It didn't work this way before... I took a look at a few things in the code and noticed this anomaly.
BTW, there are root or branch level folder showing the Read Only attribute is inherited from parent folder... but my whole C drive is this way... but LV should be able to write to the file regardless....

WebUtil dll download error: Unable to write to local file

Hi,
Hopefully I'm putting this in the correct forums.
I'm setting up a Forms application that uses webutils.
We're running Forms and Reports standalone (10.1.2.3.0) running on Solaris Sparc (64bit) and have just applied patch 7703734.
As per Oracle Support doc [ID 783937.1], I'm trying to set the download location for the webutil libraries:
install.syslib.location.client.0 = C:\webutil
However, I'm gettting the following error message in the Java 6u16 console (repeated for each of the 3 webutil files)
*2011-Feb-07 12:24:16.988 ERROR>WUC-19 [URLDownload.pullFile()] Unable to write to local file C:\webutil\::dev\d2kwut60.dll. Failed to download URL http://appdev02:7787/forms/webutil/d2kwut60.dll*
I've done a bit of searching and most of the answer's I've come across refer to Vista or Windows 7 and UAC. Unfortunately the SOE for this app is XP Pro SP3.
It's probably something simple I'm missing , but would appreciate and pointing in the right direction.
If you need any more info, let me know.

Hello
the problem also appears with windows vista
i found a solution but it's not a good one
if you download the files into the java directory
you can modify the userrights and give the user "everyone" the right 'write' for the bin directory.

Ebook error message: "Fail to write destination file error"

I am attempting to transfer ebooks (checked out via my library's ebook consortium) from Adobe Digital Editions to my Nook. I have done this in the past with no issues, but recently I have been getting the following error message: "Fail to write destination file error".
I know the issue is NOT lack of space on my Nook (I cleared it of all info and still received the error message).

I had this problem as well, and after doing some research via google (because I found NOTHING helpful in adobe forums), I found the problem....my Nook was full. I had no idea this was even possible! But, I borrow a lot of library books, and didn't realize that after they expire, they are still taking up space on my Nook. Here's how to check: plug your Nook into your computer, go to file manager (right-click the start button in Windows), find the Nook drive and right click, choose properties. This should show you a pie chart of used/free space on your Nook. If this is the case, you need to remove some files from your Nook. For me, I had to find the Digital Editions file and delete all the thumbnails and actual files for the library books. If it's booked you've purchased, perhaps you need to archive some books. Hope this helps!

Write characters to file gives a file not found error

It appears that it generates the error at the open file sub vi, but I have no problem with write to spreadsheet file which uses the same sub vi.
Jim
LV 2013

Sorry to answer with some questions..
Which version of LV are you using?
Does the file that you attempt to write to, exist? Do you specify a filename in your vi?
Otherwise,(in LV7) you will be prompted for a file. If it does not exist, the subvi will create it. If it exists, it will ask if you want to overwrite it.
Experiment with the "Write Character to File" vi by simply connecting a string to it... and run it.
BTW, your file must be closed when you attempt to write to it, otherwise the error is actually from Windows.
If you want to append to an existing file (add to it without deleting the original contents), then wire a TRUE to "Append to file". Of course, your file path should be filled in with an appropriate path & filename. In t
his case, you will not be prompted for a filename. However, you can experiment without providing (wiring) a path & filename, let LV prompt you.
Try this as a starting point. You should not get an error. If you still do, can you write what the error message is?
