vCO and reading/writing files

Hello community,

I am a newbie with vCO, sorry for the basic question perhaps.

I created a "workflow" for automatic deployment and customization of VMs. job well enough, the model is cloned, sysprep, vCPUs and RAM set and so one. But the final customization tasks is to assign a unique IP address that is in a list in a plain text file. vCO should open the file, take the first IP address in the first line, remove it and close the file (DHCP is not an option). I can open and read the file with the options of '.readall' and a 'player', but which is not exactly what I want. I tried a few '.readline' which translates as "cannot find function readline" and after I I thought to split the entire string that resulted in "no defined split." I really don't know if this is the right way.

Can someone please guide me in the right direction, perhaps with a few code snippets?

Thank you very much!

OK, here's another example, which reads the entire file into a string, and then use split() for areas exploded in the elements of an array:

var fr = new FileReader("C://vcoscripts/demo.txt");
fr.open();

var complete = fr.readAll();
System.debug("complete: " + complete);
var lines = new Array();
lines= complete.split(/\r\n|\r|\n/);
System.debug("lines: " + lines);
for (var linenr in lines) {
    var currentLine = lines[linenr];
    System.debug("currentLine: " + currentLine);
    }

With this, you can use methods of standard table (push(), pop()), which might be easier to use.

The regular expression to split the lines that I got:

(good reading...)

Edit: I forgot: with Array.strip (), you can remove an element of a table (in your case the IP address used before writing it back to deposit via FileWriter...)

Kind regards

Joerg

If I put a restriction of password which only allow customers who purchase print it (no copy or modification of the document) have an impact on the quality of the file when people open and read the file on mobile devices like phones and tablets?

If I put a restriction of password that only allow users who buy to print it (no copies or the modification of the document allowed)-it will have no effect on the quality of the file when people open and read the file on mobile devices like phones and tablets?

Some mobile devices won't be able to open it at all, but if it is open, the quality is not affected. Please note and understand the warning you get when you set security: indeed, it is largely ignored by many apps.

Why not download and read .pdf files

I never had no problem download and playback of .pdf files to what I 'upgraded' Adobe reader version 11. Now all the downloads of attempts fail because "I don't have the necessary helper or same C:\DOCUME~1\Will-o\LOCALS~1\Temp\Back channel II - betrayal of the Viet Nam - ch. 1 & 2. PDF cannot be opened, because the associated helper application does not exist. Changing the association in your preferences. What in the world is happening and how to fix it?

Under "Tools - Applications - Adobe Acrobat Document, the I chose 'Use Adobe Reader'." However since I also have Adobe Acrobat 8.3, I tried substitution, for the reader, but which does not work either. Help, please.

You could try the following:

(1) change your preference for 'Preview in Firefox' and use the download button to save the file. But it's an extra step.

(2) change your preference to "Always ask" and see if you can get the file to open it in this way.

(3) delete the file from your application's preferences (it is sometimes damaged) and try again. Note: these are only the preferences for which applications manage what types of content, not all your Firefox preferences.

To do this:

(i) open your current Firefox settings (AKA Firefox profile) folder using

Help > troubleshooting information > "view file" button.

(ii) switch back to Firefox and the output. Your Windows Explorer window should go back to the foreground. Pause while Firefox finishing its cleanup.

(iii) and rename the mimeTypes.rdf something like mimeTypes.old

(iv) restart Firefox. It is likely you will default to 'Preview in Firefox' and I hope that the paths for Adobe Reader and Adobe Acrobat will now be correct if you choose one of those.

A little luck?

reading / writing file of computer network

HelloW!

I have to read pc specific network, save/display the path file and then write back the file I've already read, and then after confirmation that the file written is correct I have proceed please guide me steps in order to achieve this... Although this is a very basic question, but I ask you to start as I've never used before network with cvi. Please provide us with some examples of code if possible

Thanks in advance

A lot depends on how you get the path to the original remote file.

If the process starts with the operator interactively by selecting the file (for example with FileSelectPopupEx), you can simply use the path returned by the function and process the remote file somehow on your PC.

Load and read XML file size more than 4 GB

Hi all
My environment is Oracle 10.2.0.4 on Solaris and I process to work with the XML file as below the detail of PL/SQL
1. I read the XML file on the HTTP port in the XMLTYPE column to table.
2. I read value n ° 1 of the table and extract of y to insert another table
On test db, everything is working but I got below error when I use the XML production
ORA-31186: Document contains too many nodes
Current XML size about 100 MB, but the procedure must take over the size of XML file over 4 GB in the future.
Below are some of my code for your info.
1. reading XML by line in variable and inserting into table
LOOP
Utl_http.READ_TEXT (http_resp, v_resptext, 32767);
DBMS_LOB. WriteAppend (v_clob, LENGTH (v_resptext), v_resptext);
END LOOP;
INSERT INTO XMLTAB VALUES (XMLTYPE (v_clob));
2. read the value of the cell in the XML column and extract to insert into another table
DECLARE
CURSOR c_xml IS
(SELECT trim (y.cvalue)
FROM XMLTAB xt.
XMLTable ('/ Table, rows, cells, cell ' PASSAGE xt.) XMLDoc
COLUMNS
cvalue VARCHAR (50) PATH ' / ');
:
:
BEGIN
:
:
OPEN c_xml;
SEEK c_xml INTO v_TempValue;
< generate the insert statement in another table >
OUTPUT WHEN c_xml % NOTFOUND;
NARROW C_xml;
:
END
And another problem is performance problem when the XML file is great, first step to XML content loading to XMLTYPE column slowly.
Could you please suggest any solution to read large XML file and improve performance?
Thank you in advance.
Hiko

Finally, change us source file to XML, CSV format and instead load the XML using SQL Loader.

Difference b/w reading synchronous file and read the file adapter Service
Can someone tell me the difference between synchronous file read the service and the service of simple reading of the file adapter functions.

where exactly do we use the synchronous file service? Please give me some example of scenario where we can use file synchronous read characteristic of service...
Synchronous reading is used for playback of files mid process. People tend to use for consuming files based on a business rule. You can specify which files you want to read. An example of this would be an an email is sent telling the faile abc.csv has been downloaded. The BPEL process shuts down gets it. You can also cheange the location of the file dynamically in the process as well.

Using the file adapter is used to call a process so when a file is placed in a place the BPEL process is called. It is most commonly used.

see you soon

Adding a delay time and reading a file

Hi there, new to labview here. Working on a project and having some problems he do on the ground.

First question, in the VI below, I try to have a delay between each entry, but when I take a glance on the control of delay, I don't see how it is supposed to implement. No singal flow through the timer.

Question 2, I want to write these ports via a xcel file but not sure how to do...

Thanks for your help in advance...

It seems that Excel adds additional bytes in it for who knows what reason. Save your spreadsheet as a CSV file and they seem to go away. Of course, you must change the format '% x, %d' string when you do this.

reading/writing files to memory, disk, SD card, memory card?

On computer, we have memory, disk and allows you to connect an external mass storage disk, for example via the USB port. I'm a little confused on what we have on Blackberry phones. I know that all phones have memory but

(1) phones Bold and Storm also have hard drives?

(2) something integrated into the phone, or is - SDCard it something I have to plug it into the phone?

(3) via the media desktop Manager, I see that Storm has a record 'media card' in addition to the record of the "memory of the device. The equivalent card SDCard?

(4) we can use a class of connector to access the files. What is the correct to a file path, if it is stored in

memory has.

b. SD card

c. Media card

d. disk (if there is such a thing)

Thanks for your help

1. No, there is no such thing as a drive. There is a flash memory based on the memory chip (like a usb flash key).

2. SD card is a memory card microSD that can be installed on the particular phone models (Pearl, Curve, 8800, Bold, Storm, Tour and newer)

3 Media card represents the contents of microSD card, peripheral content device memory internal memory.

I was redirected here Creative Forum of Suites. Seems a very simple and obvious question, but I do not see the simple and obvious answer.

Yes, the latest versions of adobe program can open the source files created in older versions.

the reverse is not necessarily true.

How to read/write files in Photoshop CC?

Hi all
I have plugin for Photoshop CC2014 and above using node.js to reading/writing files, download remote files and restful calls. It does not in Photoshop CC because CC uses 4 CSXS and node.js is not available here. So is it possible in javascript to perform these operations (reading/writing/download) in CSXS4? I think I can use XMLHttpRequest to download files, but how to read and write? Thank you!

Develooping app for Windows Store - writing and reading file: file came from another computer

I am developing an app Store Windows (XAML, c#) and I am writing a file to the user Documents folder. When writing is complete, the file is marked as «this file came from another computer and can be blocked to protect the computer» Of course, this isn't what I want - the file did not come from another computer. Subsequent attempts to read the file in the same application fail unless I have use Windows Explorer to unlock the file.

How can I write a file in a way that I don't let not blocked for the following readings?

"Read binary file" and efficiency

For the first time I tried using important binary file on data files reading, and I see some real performance issues. To avoid any loss of data, I write the data as I received it acquisition of data 10 times per second. What I write is an array double 2D, 1000 x 2-4 channels data points. When reading in the file, I wish I could read it as a 3D array, all at the same time. This does not seem supported, so many times I do readings of 2D table and use a shift with table register building to assemble the table 3D that I really need. But it is incredibly slow! It seems that I can read only a few hundred of these 2D members per second.

It has also occurred to me that the array of construction used in a shift register to continue to add on the table could be a quadratic time operation depending on how it is implemented. Continually and repeatedly allocating more larger and large blocks of memory and copy the table growing at every stage.

I'm looking for suggestions on how to effectively store, read effectively and efficiently back up my data in table 3-d that I need. Maybe I could make your life easier if I had "Raw write" and "read the raw data" operations only the digits and not metadata.then I could write the file and read it back in any size of reading and writing songs I have if you please - and read it with other programs and more. But I don't see them in the menus.

Suggestions?
