How can I write to text file colorful texts

I save system events in a text file,for example when system give warning message i want to write it red

As others have mentioned, if you want to view text in different colors with an viewer/editor tool outside of LabVIEW, you must provide the necessary formatting for that tool.
If it works for your application to view the file using LabVIEW you can do this:
1) Place a unique key in each line that identifies an error.
2) Display the text in a Listbox and color each line based on that unique key.
You can fairly easily provide a stand alone viewer if needed.
This technique can also be expanded to provide multiple colors.

How can I write some informations in a text file ?

Hello.
I am a beginner in java in general and in Web Dynpro Java in particular.
I have to work in an application written by a consultant wich works no more at my office.
Due to performances problems (slowness of the application at unpredictable instants),
I have to write in an external file all the actions which make the users in the application.
The problem is I don't know how to proceed.
Somebody can help me ?

Hi Serge,
You can try this as well to generate a text file.
Use Filedownload UI element. And try following code in Webdynpro.....
IOUtil IOUtil=new IOUtil();
File f = new File("skill_master.txt");
FileWriter fw = new FileWriter(f);
fw.write(formattedStr);
fw.close();
InputStream template = new FileInputStream(f);
ByteArrayOutputStream templateSourceOutputStream = new ByteArrayOutputStream();
IOUtil.write(template, templateSourceOutputStream);
IWDCachedWebResource resource=WDWebResource.getWebResource(templateSourceOutputStream.toByteArray(), WDWebResourceType.getWebResourceType( "txt","text/html"));
resource.setResourceName("User.txt");
wdContext.currentContextElement().setVa_FileData(resource);
Here formattedStr is the string which contain all the contents you want in the file. Here Va_FileData attribute is of type com.sap.ide.webdynpro.uielementdefinitions.Resource.
Map this Va_FileData attribute to the Filedownload UI. So that when u click on the FileDownload UI it will generate a txt file.
Hope it helps you.

Swati

How can I open in java file a text file?

Hi !
For example I have a java file name Pencil.java and I have a text fie name Box.txt
I want like that if ( a == b ) {open Box.txt}
How can I do that ?
Thanks.

Yes I want to see what this text file contains. Like clicking to a text file with mouse and opens. Then I can see what it contains.
I have a Java document Pencil.java and I have a text file Box.txt
I will write a java code in pencil.java ( that I dont know ). Then when I enter a number from keyboard with
Scanner write = new Scanner(System.in);
int a = write.nextInt()
if (a == b) { } opens Box.txt
For example
I write to command prompt
java pencil
It wants from me a number : I will enter 3.
It is same as b .
Then Box.txt file opens.

How can I write to a file from a livecycle designed PDF?

I am producing a PDF in Livecycle designer and would like to write a sub-set of data from the document.
I have tried methods such as exportData() but this exports everything which i don't need.
I have seen another method which is to attach a file and write to that but ideally I'd just like to be able to create a new file.
var data = xfa.data.nodes.item(0).nodes.item(1).saveXML() var oFile = util.streamFromString(data , "utf-8");
I would like to write oFile.
Thanks in advance
Edit:
I would like to add that ideally the user would be presented with a save as dialog box, so the can choose the location of where to save the xml data.

an extraction out of expert one-on-one from Thomas Kyte
<quote>
when an oracle istance is created the services that support it are setup to 'log on as' the system (or operating system) account, this account has very few privileges and no acces to Window NT Domains. To access another Windows NT machine the OracleServiceXXXX must be setup to logon to the appropriate Windows NT Domain as a user who has acces to the required location for UTL_FILE.
To change the default logon for the Oracle services go to (in Windows NT):
Control Panel | Services | OracleServiceXXXX | startup | log on as; (where XXXX is the instance name)
In Windows 2000, this would be:
Control Panel | Administrative Tools | Services | OracleServiceXXX | Properties | Log on tab; (again XXXX is the instance name)
Choose the This Account radio button, and then complete the appropriate domain login information. ONce the services have been setup as a user with the appropriate privileges, ther are two options dfor setting UTL_FILE_DIR:
* Mapped Dirve: To use a mapped drive, the user that the service starts as must have setup a drive to match UTL_FILE_DIR and be logged onto the server when UTL_FILE is in use.
* Universal Naming Convention: UNC is preferable to Mapped Drives because it does not require anyone to be logged on and utl_file_dir should be set to a name in the form \\<machine name>\<share name>\<path>
You will of course need to stop and restart Oracle after changing the properties of the service.
<\quote>
I want to write some data to a (external) file. I have it working with the function UTL_FILE.
My problem is I want to write to a file on a mapped drive (so a drive on a different machine). This is not working.
Does anyone know a way to build this.

How can I write to data file only near to SW Trigger samples?

Hi everyone
I am working on a model based in this one:
http://zone.ni.com/devzone/cda/epd/p/id/34#0requirements
I would like to save the data once the trigger is reached, with some data near to the impact.
Where should I place a "write to measurement file" block in order to may load and plot the data of an impact test?
Regards.
Solved!
Go to Solution.

Celuti,
You are so close!
I am glad to see you understood what I recommended!
You need to ensure that you connect the same data type to the Queue as what is coming from the DAQ.
Please see the modified version of the code you posted.

How can I read the bootstrap files and extract the fragment-URLs and fragment-numbers in plain text?

How can I read the bootstrap files of any HDS Live stream and extract the fragment-URLs and fragment-numbers in plain text?
Could it be that it is some kind of compressed format in the bootstrap? Can I uncompress it wirh f4fpackager.exe? Could not find any download for f4fpackager.exe. I would prefere less code to do so. Is there something in Java of JavaScript, that can extract the fragment-numbers?
Thank you!

Doesn't sound too hard to me. Your class User (the convention says to capitalize class names) will have an ArrayList or Vector in it to represent the queue, and a method to store a Packet object into the List. An array or ArrayList or Vector will hold the 10 user objects. You will find the right user object from packet.user_id and call the method.
Please try to write some code yourself. You won't learn anything from having someone else write it for you. Look at sample code using ArrayList and Vector, there's plenty out there. Post in the forum again if your code turns out not to behave.

Exporting photos for UHDTV or Native 4K TV, what are the best settings ? (File: Quality File: Color Space, Image Sizing and resolution) Or in other words; How can I get the smallest files but keep good quality for display on new UHDTV

You're welcome, and thank you for the reply.
2) Yesterday I made the subclips with the In-Out Points and Command-U, the benefit is that I've seen the clip before naming it. Now I'm using markers, it's benefit is that I can write comment and (the later) clip name at once, the drawback is that I have to view to the next shot's beginning before knowing what the shot contains.
But now I found out that I can reconnect my clips independently to the format I converted the master clip to. I reconnected the media to the original AVI file and it worked, too! The more I work with, the more I'm sold on it... - although it doesn't seem to be able to read and use the date information within the DV AVI.
1) Ok, I tried something similar within FCE. Just worked, but the file size still remains. Which codec settings should I use? Is the export to DV in MOV with a quality of 75% acceptable for both file size and quality? Or would be encoding as H.264 with best quality an option for archiving, knowing that I have to convert it back to DV if I (maybe) wan't to use it for editing later? Or anything else?
Thank's in advance again,
André

Yes, you must change block (Get Date/Time String.vi).
You must write new subVI - this new VI convert date and time to the second [or ms or us].
First choice is: time column will be count of second [the better ms or best us] since 12:00 a.m., January 1, 1904, Universal time[function "Get Date/Time In Seconds.vi"].
Text file:

3216546154,100 0.125333
Second choice is: first record in TXT file will be time when test start and after will be table with time [ms or us] and value.
Text file:
Start time: Monday 30-th February 2005.

How can i write also to xml file the settings of the Tag property to identify if it's "file" or "directory" ?

The first thing i'm doing is to get from my ftp server all the ftp content information and i tag it so i can identify later if it's a file or a directory:
private int total_dirs;
private int searched_until_now_dirs;
private int max_percentage;
private TreeNode directories_real_time;
private string SummaryText;
private TreeNode CreateDirectoryNode(string path, string name , int recursive_levl )
var directoryNode = new TreeNode(name);
var directoryListing = GetDirectoryListing(path);
var directories = directoryListing.Where(d => d.IsDirectory);
var files = directoryListing.Where(d => !d.IsDirectory);
total_dirs += directories.Count<FTPListDetail>();
searched_until_now_dirs++;
int percentage = 0;
foreach (var dir in directories)
directoryNode.Nodes.Add(CreateDirectoryNode(dir.FullPath, dir.Name, recursive_levl+1));
if (recursive_levl == 1)
TreeNode temp_tn = (TreeNode)directoryNode.Clone();
this.BeginInvoke(new MethodInvoker( delegate
UpdateList(temp_tn);
percentage = (searched_until_now_dirs * 100) / total_dirs;
if (percentage > max_percentage)
SummaryText = String.Format("Searched dirs {0} / Total dirs {1}", searched_until_now_dirs, total_dirs);
max_percentage = percentage;
backgroundWorker1.ReportProgress(percentage, SummaryText);
percentage = (searched_until_now_dirs * 100) / total_dirs;
if (percentage > max_percentage)
SummaryText = String.Format("Searched dirs {0} / Total dirs {1}", searched_until_now_dirs, total_dirs);
max_percentage = percentage;
backgroundWorker1.ReportProgress(percentage, SummaryText);
foreach (var file in files)
TreeNode file_tree_node = new TreeNode(file.Name);
file_tree_node.Tag = "file";
directoryNode.Nodes.Add(file_tree_node);
numberOfFiles.Add(file.FullPath);
return directoryNode;
The line i'm using to Tag is:
file_tree_node.Tag = "file";
So i know what is "file" then i make a simple check if the Tag is not null then i know it's a "file" if it's null then it's directory.
For example this is how i'm checking if it's file or directory after getting all the content from my ftp server:
if (treeViewMS1.SelectedNode.Tag != null)
string s = (string)treeViewMS1.SelectedNode.Tag;
if (s == "file")
file = false;
DeleteFile(treeViewMS1.SelectedNode.FullPath, file);
else
RemoveDirectoriesRecursive(treeViewMS1.SelectedNode, treeViewMS1.SelectedNode.FullPath);
I also update in real time when getting the content of the ftp server xml file on my hard disk with the treeView structure information so when i'm running the program each time it will load the treeView structure with all directories and files.
This is the class of the xml file:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Xml;
using System.Windows.Forms;
namespace FTP_ProgressBar
class TreeViewXmlPopulation
// Xml tag for node, e.g. 'node' in case of <node></node>
private const string XmlNodeTag = "node";
// Xml attributes for node e.g. <node text="Asia" tag=""
// imageindex="1"></node>
private const string XmlNodeTextAtt = "text";
private const string XmlNodeTagAtt = "tag";
private const string XmlNodeImageIndexAtt = "imageindex";
public static void DeserializeTreeView(TreeView treeView, string fileName)
XmlTextReader reader = null;
try
// disabling re-drawing of treeview till all nodes are added
treeView.BeginUpdate();
reader = new XmlTextReader(fileName);
TreeNode parentNode = null;
while (reader.Read())
if (reader.NodeType == XmlNodeType.Element)
if (reader.Name == XmlNodeTag)
TreeNode newNode = new TreeNode();
bool isEmptyElement = reader.IsEmptyElement;
// loading node attributes
int attributeCount = reader.AttributeCount;
if (attributeCount > 0)
for (int i = 0; i < attributeCount; i++)
reader.MoveToAttribute(i);
SetAttributeValue(newNode,
reader.Name, reader.Value);
// add new node to Parent Node or TreeView
if (parentNode != null)
parentNode.Nodes.Add(newNode);
else
treeView.Nodes.Add(newNode);
// making current node 'ParentNode' if its not empty
if (!isEmptyElement)
parentNode = newNode;
// moving up to in TreeView if end tag is encountered
else if (reader.NodeType == XmlNodeType.EndElement)
if (reader.Name == XmlNodeTag)
parentNode = parentNode.Parent;
else if (reader.NodeType == XmlNodeType.XmlDeclaration)
//Ignore Xml Declaration
else if (reader.NodeType == XmlNodeType.None)
return;
else if (reader.NodeType == XmlNodeType.Text)
parentNode.Nodes.Add(reader.Value);
finally
// enabling redrawing of treeview after all nodes are added
treeView.EndUpdate();
reader.Close();
/// <span class="code-SummaryComment"><summary>
/// Used by Deserialize method for setting properties of
/// TreeNode from xml node attributes
/// <span class="code-SummaryComment"></summary>
private static void SetAttributeValue(TreeNode node,
string propertyName, string value)
if (propertyName == XmlNodeTextAtt)
node.Text = value;
else if (propertyName == XmlNodeImageIndexAtt)
node.ImageIndex = int.Parse(value);
else if (propertyName == XmlNodeTagAtt)
node.Tag = value;
public static void SerializeTreeView(TreeView treeView, string fileName)
XmlTextWriter textWriter = new XmlTextWriter(fileName,
System.Text.Encoding.ASCII);
// writing the xml declaration tag
textWriter.WriteStartDocument();
//textWriter.WriteRaw("\r\n");
// writing the main tag that encloses all node tags
textWriter.WriteStartElement("TreeView");
// save the nodes, recursive method
SaveNodes(treeView.Nodes, textWriter);
textWriter.WriteEndElement();
textWriter.Close();
private static void SaveNodes(TreeNodeCollection nodesCollection,
XmlTextWriter textWriter)
for (int i = 0; i < nodesCollection.Count; i++)
TreeNode node = nodesCollection[i];
textWriter.WriteStartElement(XmlNodeTag);
textWriter.WriteAttributeString(XmlNodeTextAtt,
node.Text);
textWriter.WriteAttributeString(
XmlNodeImageIndexAtt, node.ImageIndex.ToString());
if (node.Tag != null)
textWriter.WriteAttributeString(XmlNodeTagAtt,
node.Tag.ToString());
// add other node properties to serialize here
if (node.Nodes.Count > 0)
SaveNodes(node.Nodes, textWriter);
textWriter.WriteEndElement();
And this is how i'm using the class this method i'm calling it inside the CreateDirectoryNode and i'm updating the treeView in real time when getting the ftp content from the server i build the treeView structure in real time.
DateTime last_update;
private void UpdateList(TreeNode tn_rt)
TimeSpan ts = DateTime.Now - last_update;
if (ts.TotalMilliseconds > 200)
last_update = DateTime.Now;
treeViewMS1.BeginUpdate();
treeViewMS1.Nodes.Clear();
treeViewMS1.Nodes.Add(tn_rt);
TreeViewXmlPopulation.SerializeTreeView(treeViewMS1, @"c:\XmlFile\Original.xml");
ExpandToLevel(treeViewMS1.Nodes, 1);
treeViewMS1.EndUpdate();
And when i'm running the program again in the constructor i'm doing:
if (File.Exists(@"c:\XmlFile\Original.xml"))
TreeViewXmlPopulation.DeserializeTreeView(treeViewMS1, @"c:\XmlFile\Original.xml");
My question is how can i update the xml file in real time like i'm doing now but also with the Tag property so next time i will run the program and will not get the content from the ftp i will know in the treeView what is file and what is directory.
The problem is that now if i will run the program the Tag property is null. I must get the ftp content from the server each time.
But i want that withoutout getting the ftp content from server to Tag each file as file in the treeView structure.
So what i need is somehow where i;m Tagging "file" or maybe when updating the treeView also to add something to the xml file so when i will run the progrma again and read back the xml file it will also Tag the files in the treeView.

How can I Write a sine wave in an Access-file?

I measure a sine wave in LabView 6i. How can I write the datas automatically to an Acces-file, at the same time?
In my program, I managed it with Execute SQL.vi, I change a number in a SQL statement(String) -> after this I push start and then it writes the statement in the Access-file.
The problem is, it writes only one data per measurement in the file. How can I write all datas in the Access-file and measure the wave at the same time?
Thanks for help!

On the waveform palette, you will find a "to components" vi that you can break out the array of the waveform. You can then, using a for loop write all of the values from the waveform.
Better yet, there are examples in the database toolkit manual on pages 3-13 to 3-15 that deal with reading arrays (and even has a waveform example).
Good luck!

Hey Atrina,
The actual data stored on disk is just the raw data (that is, a byte per sample in your case). It's really just a matter of how that data is being represented in LabVIEW whenever you read back the TDMS file.
I'm not sure if there is a better way to do this, but here is a way to accomplish what you're wanting:
Read back the TDMS file as a digital waveform. Then there's a conversion function in LabVIEW called DWDT Digital to Binary. This function will convert that set of digital channels into the "port format" that you're wanting. I've attached an example of what I mean.
Note: When looking at this VI, there are a few things that the downgrade process did to the VI that I would not recommend for these TDMS files. It added a 1.0 constant on the TDMS Open function, and it set "disable buffering" on the TDMS Open function to false; you can get rid of both of those constants.
