How can i generate AMI line codes in LabView signal express?

i wish to conduct a project that uses AMI line codes. but i have a hard time using signal express to generate it. can anyone help me with that?

Hello Barry,
That is really a problem, in LabVIEW, we can only convert vi to the previous version, I have version 7.1 and so I can only convert to version 7.0 and you cannot open this too.
But I think that it's very easy to do what I'm trying to explain you.
Go to the cluster group in the functions pallete. Place an unbundle by name function in the diagram and connect it to the data that's comming out of the FFT Power spectrum vi - the pink (or watever) wire.
Click in the white part of it (it should contain something like f0), choose magnitude.
This is now an array that you can connect to the peak detector function.
Take care about the threshold and width parameters of the peak detector.
Take a look at your signal and decide the amplitude and width of the peaks you want to detect. The threshold is the amplitude above what you consider as a peak, the width is a little bit more complicated - to begin, 3 or 4 should be a good number if you signal is not too noisy - bigger widths will somehow do a kind of a low pass filtering to your signal.
The position output of your peak detector is an array of locations where your peaks were found.
Keep in mind you are now working in frequency domain and that position means something in the frequency domain.
The array you placed as input of the peak detector is an array of points starting in f0 and separated by df (the other elements of the cluster).
So to calculate the real value of the peaks, you have to multiply them by df and add them f0.
Sorry by the big text and sorry if I went too much in detail,
Hope it helps,
Paulo

How can i build a manchester coding in labview signal processing?

how can i build a manchester coding in labview signal processing?

Check out the LabVIEW FPGA example http://zone.ni.com/devzone/cda/epd/p/id/6126
Generate Manchester Signal
Basic example showing generation of a Manchester encoded data stream. The data to be sent is generated in one loop and passed to a FPGA FIFO. The subVI which generates the Manchester data stream reads the data bytes form the FIFO and passes them to the digital output. The subVI prepends a simple header to each data packet which allows a reader (see next example) to synchronize and acquire/parse the data. The header consists of a thee half bit pulse followed by a one half bit pulse. The three half bit pulse is not a valid component of regular Manchester encoding and can therefore be differentiated from the rest of the protocol. In addition it can be used by the receiver to to easily measure the bit rate of the protocol. By dividing the length of the three half bit pulse in half (3/4 of a bit), the receiver has a measure to differentiate between full and half bit pulses in the rest of the protocol.
Generate and Read Manchester Signal
An extension of the previous example which adds a Manchester receiver subVI. You must physically wire the digital output channel to your input channel to loop back the data outside the I/O connector of your FPGA R series card or C series module. The Manchester receiver subVI is expecting the data packet to be prepended by a header as explained in the previous section.
I will see if the is a more precise example but this should help

How can I generate a staircase waveform in Labview

Hello,
How can a staircase waveform be created in Labview. I have attached the waveform needed.

staircase.xls ‏16 KB

A waveform typically has a constant time increment between points. Your xls example has two y values for each even timepoint so to reproduce your example directly would be a bit tricky. Attached is one possible very simple solution that has a constant dt.
Modify as needed.

How can I generate a map file with LabVIEW?

We wish to use a product which inserts code into our executable to prevent tampering with it by crackers. The program, however, takes the executable file, as well as the map file (which is commonly generated by c++ compilers) and uses the map file to determine where in the exe the critical routines that need protection are at. I can not, however, determine how to create such a map file for a LabVIEW generated executable. Is there a special build option I need to invoke?

Yes, I'm familar with NI's licensing technology, having talked with someone (you, Dennis, I believe) about it before. The problem we have is our software is sold to factories in China where there are no internet connections. We have a physical key 'dongle' which must be present in order for the executable to be willing to run. However, it appears that people are taking the executable which LabVIEW creates and they are editing it, probably by using a a debugger and tracing to the the code which checks for the dongles presence and bypassing it. To my knoweledge, NI's products don't do anything to prevent this, right?
We found a company which sells a product that encryptes, checksums, etc... an executable file, but it needs to know the layout of functions in the exe in order to determine which areas to focus the obfuscation on. They were sort of matter of fact when they said it needs the exe and the map file, as if they expected any language which produced an exe could produce a map file.

How can I get the time for a simulate signal express vi waveform?

I tried converting to an array and then indexing, but every index I try only gives me the y value. See attached VI for clarification on what I mean.

You will have to keep track of that yourself. You are sampling at 360kHz. This means that each sample is ~2.8us. You can easily get the time by taking that dt (2.8us) multiplied by the sample index and adding the time at which the first sample was taken.

How can i write this C-Code in G-Code

hallo
how can I write this C-Code in LabVIew ,
for a=0; a=<10; a++
for b=0; b=5 ; b+2
X= 3+b;
Y=1+a;
please see the attachment and tell me where is the problem

Unbenannt 11.vi ‏43 KB

Well, at least you tried and got some of it right.
I think this should do what you want, but my C is rusty. Is the increment performed before or after the loop executes? If it's after, then I believe the loop should iterate 11 times, not 10.
In any case, you should note that for a literal translation, you would need to add a sequence structure to guarantee that Y was written to only after the inner loop finished because of the way data-flow works.. Also, note that controls and indicators in LabVIEW are not equivalent to variables. They can be used as such, but they usually should not be.
Another point about this is that you probably want to use the correct data type - the orange terminals are floating point indicators (of double precision, in this case) and you want integers.
To learn more about LabVIEW, I suggest you try looking at some of these tutorials.

How can hide the command line of a t.code in the portal

Dear Experts.
I have the following doubt:
How can hide the Command Line of a Report that is called with a T.Code in the portal?
Attach Image:
[Image T.Code|http://www.freeimagehosting.net/uploads/eab3b6a03c.jpg]
When I created a service using the T.Code SICF for the T.Code , I can hide buttons and the filed command line using
~webgui_simple_toolbar
~singletransaction
~NOHEADEROKCODE
With notes 1010519, "SAP GUI for HTML: Simplified Title Area Without Menu and OK Code" and 959417.
But the problem is that when I create the service in the T.Code SICF, I also have that create an Iview IAC in the portal.
The Question is : How can hide this fields and buttons if I want Publish the T.code using an Iview Transaction in the portal?
In this moment I have used the two options:
1 option) I created a service using the t.Code SICF for my Transaction and I also created an Iview IAC in the portal for call the service.
RESULT:
SAP Web Application Server
         500 Connection timed out
        Error: -5
       Version: 7000
       Component: ICM

       Line: 2698
       Server: xyxab...
Error Tag: {-}
Detail: Connection to partner timed out after 60s
2) created an Iview Transaction in the portal and call my transaction.
RESULT.
[Image T.Code|http://www.freeimagehosting.net/uploads/eab3b6a03c.jpg]
But not can hide the field Command Line and other buttons.
I think that the command :
~webgui_simple_toolbar
~singletransaction
~NOHEADEROKCODE
Only can be used if I create a service using the T.Code SICF .
Best Regards
Carmen.

Hi Carmen,
The bottom line is that this cannot be done for transaction iviews without modifying the standard webgui service in SICF, which is probably not a good idea (since it affects everyone using SAP GUI for HTML). (You could hack the appintegrator to add the ~webgui_simple_toolbar parameter to the transaction URL template in the portal, but again its not a recommended thing to do ...). Better to create an IAC service in SICF with ~webgui=1 where you set the required appearance using an appropriate value for ~webgui_simple_toolbar, and then create an IAC iview to point at this service.
You can even override the ~transaction value configured in the new service in individual IAC iviews by entering the appropriate value in the application parameter of the iview, for example:
~okcode=/nSU01
And you can pass parameters in the same way:
~okcode=/nSU01 USR02-BNAME=xyz;USREFUS-USERALIAS=abc;
By the way, it would not be recommended to create a URL iview to access an IAC, since you are likely to encounter session management issues in this scenario - better to use an IAC iview.

How can we know the source code no.of lines

hi guys!
please help me, how can we check the source code(No. of lines)in program with out comments

hi,
Use this code. Replace with your program name with the text in bold. V_lines gives the no of lines of code excluding comments and as well blank lines.
TYPES: BEGIN OF t_type,
         line(72),
       END OF t_type.

How can i use the project code instead of project xml?

hello
i use the sessionbean+toplink structure,after i finish the o-r mapping by using the mapping work bench,i generate the project xml file,then in the "session.xml" file,i refer to the project xml,then i can use it from sessionbean.
i hear that if i use the project code instead of project xml file,it will be more performant,is that true?
otherwise,how can i use the project code instead of project xml file?i mean, in "session.xml", i can use the "<project-xml>" tag to refer to the project xml file,then in my session bean,i get the server session by read the "session.xml" file.but if i use the project code,how can i refer it from the "session.xml"?the examples that come with the toplink installation only tell me how can i use the project xml file within the session bean,it don't give me any clue about using the project code in the sesion bean,who can give me a step-by-step instruction and code snippet?
thank you very much?

There is a slight performance gain during session load at startup but there is no difference at runtime. The choice of which to use is dependent upon you build process. Whether it is easier to submit a new version of the class into the comile build process vs an XML file. In most cases it is just a preference of the development team.
When you use the project-class you'll need to generate the source code and compile it into your system. Typically it is packaged with the persistent classes. You may need to configure your environment so that the class-loaders have access to these classes (same for the XML case).
When using the project-class you simply replace the project-xml entry like this:
<project-class>oracle.toplink.demos.employee.relational.EmployeeProject</project-class>
The DTD for the session.xml file is found at <TOPLINK_HOME>\core\sessions_4_5.dtd. It is also in the documentation at:

How can I generate javadoc in PDF format?

Hi,
How can I generate javadoc in PDF format?
Thanks,
Fayezin

HTML to PDF with Java, using OpenOffice.org - example here: [http://www.dancrintea.ro/html-to-pdf/|http://www.dancrintea.ro/html-to-pdf/]
You can use OpenOffice.org, running as a server and command it remotely for document convertion.
Besides HTML to PDF, there are also possible other convertions:
doc --> pdf, html, txt, rtf
xls --> pdf, html, csv
ppt --> pdf, swf
Code example:
import officetools.OfficeFile; // this is my tools package
FileInputStream fis = new FileInputStream(new File("c:/test.html"));
FileOutputStream fos = new FileOutputStream(new File("c:/test.pdf"));
// suppose OpenOffice.org runs on localhost, port 8100
OfficeFile f = new OfficeFile(fis,"localhost","8100", true);
f.convert(fos,"pdf");

How can I eliminate quicktime error code 36

How can I eliminate quicktime error code 36

Hello,
Error -36 stands for an I/O Error.
File is not readable. You would need to generate a clean, error-free copy of the damaged file. Since some segments of the file are not readable, the best that can be done is to skip them.
See: http://aeroquartet.com/movierepair/quicktime-errors
and

Kind Regards,

I hav tried to generate that xml by using StringBuffer & append, but it's not what i mean...
Anyone can help me?

Ok...i got it. But i still hav some problems.
This is the sample code that i used :
public class XMLCreator {
     //No generics
     List myData;
     Document dom;
        Element rootEle, mmsEle, mmsE;
        StringWriter stringOut;
        mms mms;
     public XMLCreator(String subject, String image, String sound,
                String video, String text, String sender, String recipient,
                int id, String date, String contentid) {
          mms = new mms(subject, image, sound, video, text, sender,
                        recipient, id, contentid, date);
                createDocument();
     public void run(){
          createDOMTree();
          print();
     private void createDocument() {
          //get an instance of factory
          DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
          try {
          //get an instance of builder
          DocumentBuilder db = dbf.newDocumentBuilder();
          //create an instance of DOM
          dom = db.newDocument();
          }catch(ParserConfigurationException pce) {
               //dump it
               System.out.println("Error while trying to instantiate DocumentBuilder " + pce);
     private void createDOMTree(){
          //create the root element <Mms>
          rootEle = dom.createElement("mms");
          dom.appendChild(rootEle);
          createMmsElement(mms);
     private Element createMmsElement(mms b){
          Element subjectEle = dom.createElement("subject");
          Text subjectText = dom.createTextNode(b.getSubject());
          subjectEle.appendChild(subjectText);
          rootEle.appendChild(subjectEle);
          //create url_image element and author text node and attach it to mmsElement
          Element imageEle = dom.createElement("url_image");
          Text imageText = dom.createTextNode(b.getUrl_image());
          imageEle.appendChild(imageText);
          rootEle.appendChild(imageEle);
          // & etc....
          return rootEle;
      * This method uses Xerces specific classes
      * prints the XML document to file.
     private void print(){
          try
               //print
               OutputFormat format = new OutputFormat(dom);
               format.setIndenting(true);
                        stringOut = new StringWriter();
               //to generate output to console use this serializer
               XMLSerializer serializer = new XMLSerializer(stringOut, format);
               //to generate a file output use fileoutputstream instead of system.out
               //XMLSerializer serializer = new XMLSerializer(
               //new FileOutputStream(new File("mms.xml")), format);
               serializer.serialize(dom);
          } catch(IOException ie) {
              ie.printStackTrace();
        public String getStringOut() {
            return stringOut.toString();
}when i tried to show the stringOut.toString() in my jsp, it's only showed string like this :
The Lords Of The Ring http://localhost:8084/movie/lotr.3gp 6281321488448 6281321488448 123 0 20070220114851 LOTR.
1. Why this is happen?i want to generate xml which its format is like above.
2. How can i send this xml (put in msg parameter) using jsp (via web) without creating the mms.xml?
3. if i want to set the msg parameter equal to mms.xml - means that msg = mms.xml, what is the data type for msg? is it an object or anything else?
Thx b4 in advance...
