Write to text file without server side

Hi,
I need to write data into a text file for saving data from my
flash movie, but I didn't have the possibility to use a
server-side.
Because my flash movies are stored on a CD and it must be
compatible with Windows and MacOS.
Is it possible to write data into a text file?
If no, can I use a third party software? Which one?
Regards

A SharedObject might work for you. Otherwise, you'll need a
'wrapper' app.
Adobe's own Director works very well for this, and AIR would
work as well.
There are also a good number of 3rd party apps, such as Zinc
and others.

Is it possible to read/write to text file without deleting it?

I know how to read from a text file and how to write to a text file. The problem that i have is i need to use a text file to store data for my application to read and also for my application to write. I would like it if i could write two programs really, one reads, the other is used to update the text file. This file is a list of verbs. I thought about using databases but i couldn't get them to work. I downloaded MySQL server 5.0 and installed it. I then downloaded the driver from http://www.mysql.com/products/driver and ran the auto installer. it said everything worked out perfectly but when i try these lines:
Class.forName("com.mysql.jdbc.Driver");
I get a SQLException that says no suitible driver
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
( I thought this driver came with the JDK but i guess not, i just read about it in a java book)
I get a ClassNotFoundException
that just says sun.jdbc.odbc.JdbcOdbcDriver
So yeah, SQL is pretty much not working. I need a solution to my problem, either by using text files, or a different type of database. I heard you could use excel to create a database but i have no idea how and i hear microsoft access could also do this, however i don't have microsoft access and i don't intend on paying for it. So, here are my questions:
1st, is there a tutorial on using excel databases in java programs
(if not)
2nd is there a way to read/write/update a text file without deleting it?
(if not)
3rd is there a way to get SQL working, i have windows vista this could be the problem
(if not)
4th what could i do to store information on the hd for reading and modifying later?
thanks, lateralus

A database might be overkill just for a list of words.
Thoughts:
<ul>
<li>What is the extent of your "file updating"? If you are just appending to the file, opening it in append mode will keep the file from being clobbered.</li>
<li>Otherwise, why not create new files instead of editting them? The file names could include a version number or timestamp, allowing the reader to select the newest one.
</li>
</ul>

How to make html file on server side from the data entered in text area

Hi!
I want to know how to make .html file on server side. Like if i enter the data in text area ( or like we normaly see when we write mail that editor) and we can use html tages in it and when user submit form all the data in that field will be saved on server side as an html formate. Is it possible to do so??? or any ruff idea how to design it???

Erm ...
Whats the problem with that?!
Ok, here the code ...

Copy a .swf file from server side to client using signed applet

Hello All,
I already have my applet signed and its working pretty well. However I want to know how can I import a .swf file into clients machine. The .swf file initially is on server side, my applet checks whether this .swf file exists already on client machine. If not it copies it to his machine.
I know how to chk if the file already exits on client machine but I am not sure how to copy this .swf file to his machine if its missing.
May be I need to set some input buffers from server side and then copy them to his machine.
Can some one throw some light on this issue ??

Hello to all Java Code Masters out thr,
I am trying to copy a .swf file from server side to client side, however I am unsuccessful in writing the correct data. By correct data I mean that , the data does gets saved on the client side in the .swf file, and the size of the .swf file on client side is as expected, but some how I don't know why the data is not the same as expected.
I tried opening up both the swf file, one which is on server side and the other which is on client side. And both looked different in the notepad.
When I opens up the client side .swf file on browser it shows nothing while the .swf file on server side worked fine.
Here is a snap shot of the two .swf files when opened in notepad:

    String playlist = ImoracleDirectory + "\\clientside.swf";
    File fplaylist = new File(playlist);
    try {
      Writer output = null;
      output = new BufferedWriter(new FileWriter(fplaylist,true));
      *System.out.println(swfcontent);*
      *output.write(swfcontent);*
      output.close();
    catch (Exception e) {
      System.out.println("Cannot create or write to the playlist");
}In above code I am trying to write the string swfcontent, which contains the data shown above in serverside.swf, to clientside.swf.
Interesting thing is that I am doing System.out.println(swfcontent); just before writing the data to clientside.swf using output.write(swfcontent);. And System.out.println does print the write data on the java console. However I dont know out of what reason the data doesnt get written correctly on the client's computer.
Kindly help me in this plzzzzzzzzzz.

Write to Text File.vi Output file all but first line start with tab

The attached PNG shows the code used to build up concatenated strings into a string array for the first four lines, thence to a string Array, to Spreadsheet String.vi and, finally, the use of Write to Text File.vi
The lower right corner shows the result loaded into a spreadsheet. Note the 3 blank entries marked by a filled red rectangle. Examination of hidden characters shows there is a tab at the beginning of lines 2, 3 and 4.
There is no tab shown in the code. How do those tabs get there? How do I stop them?
I have tried with the option "Convert EOL" both on and off with no difference.
The Help states that an OS-dependent EOL character is appended to each line. I can't imagine the Windows EOL character includes a tab.
Solved!

I am still puzzled as to why those additional tabs were added by Array to Spreadsheet String. I'm holding in my hand a printout of an old LabVIEW 8 program with that construction, which is known to work properly.
Makes complete sense when you look at your code. You build a string, including an end-of-line character, and put that string into an array. Then, when you run it through Array to Spreadsheet String, it puts a tab after every array element, and new line at the end of each row in the array. The first element of your array contains a new line but Array to Spreadsheet String doesn't know about it; it still inserts a tab between that array element and the next one, giving you the tabs.

Write to text file problem

I have a write to 'text file' in a sub vi. It is a popup where user can change his program.
For some reason, only the first time it is called, it actually writes to the text file.
As long as the sub vi is in memory, and I call it again and press ok to write to text file, nothing happens.
I've tried 'close file', but that doesnt help. Deleting the files from the disk before again calling the sub vi doesnt help either, it wont write
to file again. Is this a bug or am I missing something?! Im on labview 2010

Post your VI (along with sub-VI's if any).

Write to text file qeustion

Hello all,
My first question about writing to text file is does the file need to be opened? i know you have the option to create, replace, open..., but does it need to be opened in order to properly write data to the file? Also if my application is running with a disk streaming file setup and i open the file that it is writing to will this cause an error or cause labview to lose control of the file and possibly stop writing to the file?
Thank you,
Matt

Feel free to experiment. Try writing to a file from multiple locations at once, and you'll see race conditions where data could be lost.
The reason for the Open, Write, Close type of software is because generally you are in a loop continually writing to a file, and the extra overhead of a Open and Close can be limited to when the software starts and closes, instead of having to open a new reference and close it every time you want to write to the file. Just open the reference once, work with it in a while loop, then close it once, must more efficient and better for applications that write many times to disk.
Is it necessary? No you can just use the Write to Text file giving it a path and data to write, but behind that function it will need to open and close the reference each time.

Write to text file. Append to existing file. Create file if file doesn't exist.

Hi folks,
up to LabVIEW 7 there was a wonderful "Write to Text File" vi which allowed the option "Append to File". Now, in LabVIEW 8, this old vi is not longer supported anymore. Instead, I am suggested to use a new "Write to Text File" vi. This vi does not offer the option "Append to File" anymore. Rather it is proposed in the online help that one should use the "Set File Position" in order to append text to the file. This much less straightforward than the old solution. Furthermore, I miss an option which would create the complete path if it doesn't exist yet.
To summarize: Isn't there really any smart "Write to Text File" vi available which offers both the options "Append" and "Create path if file does not yet exist". Of course, I could write such a file on my own but I am sure that it is of such general interest that it already exist. In any situation, when a log file shall be written, the wanted vi would be ideal.
Thanks a lot,
Peter

Ray,
I know that the old vi is still available. See the screenshot which I attach to this message. What I am missing is an option "Create file or even complete path if file or path do not yet exist.". Is there any reason why NI doesn't provide neither this option nor a simple "Append to file" functionality in the new "Write to Text File" vi?
Regards,
Peter

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.

The same goes for "read from text file

Hello!
Look at the following examples shipped with LabVIEW Professional and LabVIEW Full. Event structure example is not installed with Base package.
Open up 'Example Finder', click on the 'Search' tab, enter keyword 'events' and you fill find several examples. The ones of interest for you is 'New Event Handler.VI" and 'Old Event Handler.VI', where the first uses the event structure and the other uses the standard state machine architecture.

Write to Text File - unflatten channel string

Hi all,
This is my first post on the forums! It's been very helpful for me but I have not been able to find a solution to my (simple) problem.
Operating system: Windows 7 (64-bit)
Labview 2012 Full Development
I'm using the DAQmx unflatten channel string to get the names of the channels, and when I Write to Text File, I get the names of channels to be displayed vertically, ie a new row for each channel in a column. I'd like to "transpose" this, but obviously you cannot transpose a 1d array. Any ideas on how I can do this?
Any and all ideas are appreciate, thank you in advance,
-AK
Solved!
Go to Solution.

Show us how you are doing this.
My guess is that once you get the data, you have linefeed characters separating the channel names rather than some other delimiter such as a comma or a tab.
Depedning on how you are going from the channel names to the file (a string, an array of strings, Write to Spreadsheet File, Write to Text file, ....) will determine the best way to fix the problem for you.

Write to text file while scrolling table issue

Hi all,
I have a LabVIEW application that logs data using 'write to text file' every second. This is a bckground task in a sub-VI. On the main screen I have several tables that have scrollbars. Every time the file is written the scrolling of a table is effectivley canceled. It is then necessary to click on the scrollbar again to re-start scrolling the table. I guess this is an issue with the OS but not sure yet. I have not tested other operating systems yet. I thought I would try the forum first. Has anyone else experienced this issue? Any ideas on how to fix this?
I have tried using list boxes instead of tables but the same issue exists.
I'm using windows 7 and LabVIEW 2011.
Thank you.
Certified LabVIEW Architect

Hi Steve, thanks for offering to help. Right now I'm on a machine with LabVIEW 2010 and XP and the issue does not exist. But I have created a little test VI that should demonstrate the issue once running on LabVIEW 2011 SP1 and Windows 7. I can't confirm this VI will demonstrate the issue until later today when I can test it on the problem system myself. Feel free to give it a go and let us know what you find, or wait until I confirm the attached VI will demonsrate the issue (10 to 12 hrs time).
Thank again.

Can you write an avi file without using imaq

Just curious if anybody has tried to write an avi file without using imaq vi's? So far I have only found sketchy info on the file format and am looking for some help on the file structure etc. Any references or example avi files with explanations of format would be most helpfull. Thanks in advance -

Absolutely.......
An AVI video file is actually structured in the same way as most Windows media files or RIFF files as they are generically known, thus the description below is applicable to for example WAV files etc.
Thus the file always begins with the four byte code RIFF and continues to use this generic four byte coding known as FOURCC, four-character code or FCC throughout.
There are then specific requirements for each different media content and the sections that must be included to define a valid file structure of the desired meadia type.
Each section or 'CHUNK' is defined by an FCC (RIFF being the first) with facility to include additional FCC's as required. The FCC is followed by a length descriptor and then the data (just for fun the odd CHUNK does not quite fit this very general overview). These chunks then align to even word boundries so padding zeros are often inserted at the end of a CHUNK to make it all nice and neat.
It is a requirement that software that does not recognise an additional custom CHUNK should ignore it, this is very easy as all you have to do is use the length descriptor to 'jump' over the CHUNK concerned.
The following is an example from the 'CLOCK.AVI' found on windows computers for a number of years...
RIFFjB AVI LISTŒ hdrlavih8
Here you can see the RIFF followed by a four byte length descriptor (4 Gigabytes), followed by various sub CHUNKS in this example the sub CHUNK is an AVI (note that it is actually 'AVI ' to conform to the FCC).
So the CHUNK structure looks a bit like this:-
RIFF ('AVI '
LIST ('hdrl'
'avih'()
LIST ('strl'
'strh'()
'strf'()
'strd'()
'strn'()
LIST ('movi'
{SubChunk | LIST ('rec '
SubChunk1
SubChunk2
['idx1']
For more information on all this you need to read the RIFF specification documentation on the MSDN website or on the MSDN Technet materials. Most of the stuff you will immediately locate will refer to the AVI file format as that is where most of the recent effort has been focused.
