Interfacing NI 5640 with my VI PLZ help

I am interfacing Ni 5640 PCI with the example VI of the modulation toolkit "QAM transceiver" using the instrument driver of PCI 5640 not the labview FPGA driver
My final constellation is with lot of errors.
I am finding problems in setting the parameters of the PCI 5640. I am using the single tone generation VI at transmiter side and Spectrum measurement example Vi at RX side.
parameters I am setting are
at TX:
sampling rate of the complex cluster I am giving to ni 5640 R write waveform is 1600k S/s
IQ rate giving to ni 5640 R configure generation is 1600k S/s
Symbol rate is 100k Hz
pulse shaping root raised cosine using 16 samples per symbol
AT RX:
what should be the span if i see in the example spectrum measurement or the IQ rate at the ni 5640 R configure acquisition
how much samples to acquire?
if my transmitted bits are 1044 and applying 4 QAM on them
how should I resample my received array of IQ data????
PLZ help or give me any example of a transceiver system interfaced with NI 5640r using instrument driver.

My tutors won't help me with my assignment plz help!!

im trying to build a website and im struggling with the flare bit i put in my original plan. the plan s for two turntables with a mixer in the mddle to act as a navagation bar.
I want to make the mixer so when the user rolls over the "home" button the word home scrolls over the led display on the top of the mixer.
I've created the mixer, buttons, and the motion tweens but i have no idea how to link the start of the motion tween to rollover of the button plz help my tutors refuse to!!
Thanks
Kev

I can only imagine that your tutors are refusing to help because you are supposed to be doing this to demonstrate that you have learned what they are teaching you.

Again got stuck with textpool experts plz help

hi experts,
plz help in resolving this issue this is very urgent.
error is
The line type of "RPOOL" must be compatible with one of the types
"TEXTPOOL".
and its coming in :
read textpool rname into rpool language sy-langu.
FOR YOUR INFORMATION:
form init_textpool using rname like rsvar-report.
FYI:
DATA: BEGIN OF RPOOL OCCURS 20,
ID(1),
NAME(8),
TEXT(80),
END OF RPOOL.
and textpool is also a structure u can check the fields in se11.
as the structure of textpool and rpool are not same
i cannot declare the type of rpool as textpool because it ill change the functionality of the prog because in the rest of the prog we r using the fields of rpool.
plz help me.

hi atish
thanks 4 ur rply
solution provided by you is not giving error but i think it ill change your functionality.
i did this::::
data: begin of rpool occurs 20,
            id(1),
            name(8),
            text(80),
      end of rpool.
data: rname like rsvar-report.
data : RPOOL_1 LIKE TEXTPOOL OCCURS 0 WITH HEADER LINE.
TYPEs : begin of RPOOL_1 ,
            id(1),
            name(8),
            text(80),
      end of rpool_1.
read textpool rname into rpool_1 language sy-langu.
MOVE-CORRESPONDING rpool_1 TO rpool.
write : rpool-id, rpool-text, rpool-name.
later on in the program we r using name and text fields but in this when i debugged it is nt able to identify name and text fields only showing the value of id bcoz id is also dere in textpool structure.

I think you need to create the build.properties file, as documented in:

How do I create a jtable with horizontalScroll bar,plz help me!

I created a jtable component,Because my table's columns has 50 items,I must need a horizontalScroll Bar.
but I find the horizontalScroll don't display,when I add record to the jtable,the verticalScroll Bar is showed.How do I create a jtable with horizontalScroll bar,can u help me!
thank you in advance!

Hi,
This piece of code will help :
     //Get the Component Adapter for taking action against resizing of
//of Panel
ComponentListenerAdapter componentAdapter =
new ComponentListenerAdapter()
//Get the scrollbar or remove the scrollbar upon resizing
protected void resizingAction()
Container tableParent = table.getParent();
if (tableParent instanceof JViewport)
//Check if the width of the Table Parent Container
//is less than the Preferred Size of the Table
if (tableParent.getSize().getWidth() <
table.getPreferredSize().getWidth())
//Yes it is
//Remove the Auton Resize Function and get the
//Scrollbar
table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF );
else
//No it is not
//Get the Auto Resize functionality back in place
table.setAutoResizeMode(
JTable.AUTO_RESIZE_SUBSEQUENT_COLUMNS);
//Add the component Adapter to the Table Header
table.getTableHeader().addComponentListener(componentAdapter);
private abstract class ComponentListenerAdapter
implements ComponentListener
          * The <code>componentHidden<code> method has no implementation
          * @param event The Event occured whenever the Component is Hidden
          public void componentHidden(ComponentEvent event)
               //No Implementaion - Intentially Left Blank
          * The <code>componentShown</code> method has no implementation
          * @param event The Event occured whenever the Component is Shown
          public void componentShown(ComponentEvent event)
               //No Implementaion - Intentially Left Blank
          * The <code>componentMoved</code> method has no implementation
          * @param event The Event occured whenever the Component is Moved
          public void componentMoved(ComponentEvent event)
               //No Implementaion - Intentially Left Blank
          * The <code>componentResized</code> method is invoked whenever the
          * component is resized. The resizing action will set the columns and
          * scrollbar to act properly
          * @param event The Event occured whenever the Component is Resized
          public void componentResized(ComponentEvent event)
               resizingAction();
* Subclasses of this override this method to determine what is to be
* done once the Component has been Resized
protected abstract void resizingAction();
Hope this will solve all your JTable horizontal resizing problems

[FlexPMD] flexpmd.html report created with zero bytes [Plz help]

hi folks,
initially i integrated FlexPMD with Maven.
when i tried to build it creates the following:
two folders:
* CSS --- contains css files
* Images --- contains image files
two files:
flexpmd.html -- created with zero bytes
pmd.xml -- it lists the violations.
my pom.xml
<plugin>
<groupId>com.adobe.ac</groupId>
<artifactId>flex-pmd-maven-plugin</artifactId>
<version>1.0.RC3</version>
<executions>
    <execution>
    <goals>
        <goal>check</goal>
    </goals>
    </execution>
</executions>
<configuration>
    <ruleSet>${basedir}/pmd-ruleset.xml</ruleSet>
    <outputDirectory>${basedir}/target/pmd</outputDirectory>
</configuration>
</plugin>
then i tried to integrate with Hudson, i configured this pmd.xml with hudson, its showing empty graph(see below)
could you tell me , why this flexpmd.html is generated with zero bytes and why i'm not able to see plotted graph
i tried the following version 1.0.RC4,1.0.RC5 and 1.1. but these versions also creating empty html report and some versions not running under hudson.
please provide the correct version and details to solve this issue.
please help in this issue, no help except this forum... i googled already did nt get any help.
correct me if i'm wrong.
thanks in advance.

Mani

I am facing a new problem with xml schema, plz help me

Hi @,
I am facing a problem with xml schema validation. Below is my code.
public void initialize(String cfgFileName) {
try {
try {
DOMParserWrapper parser = (DOMParserWrapper)Class.forName("dom.wrappers.DOMParser").newInstance();
parser.setFeature( "http://apache.org/xml/features/dom/defer-node-expansion",true );
parser.setFeature( "http://xml.org/sax/features/validation",true);
parser.setFeature( "http://xml.org/sax/features/namespaces",true );
parser.setFeature( "http://apache.org/xml/features/validation/schema",true );
parser.setFeature( "http://apache.org/xml/features/validation/schema-full-checking",true );
Document document = parser.parse(cfgFileName);
System.out.println("Vijay .. code .. damar\n");
}catch (org.xml.sax.SAXParseException spe) {
} catch (org.xml.sax.SAXNotRecognizedException ex ){
} catch (org.xml.sax.SAXNotSupportedException ex ){
} catch (org.xml.sax.SAXException se) {
if (se.getException() != null)
se.getException().printStackTrace(System.err);
else
se.printStackTrace(System.err);
}catch (Exception e) {
System.out.println("Caught unknown exception : \n");
e.printStackTrace(System.err);
System.out.println("Vijay .. code .. success\n");
DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder();
//docBuilder.setErrorHandler(myErrorHandler);
cfg = docBuilder.parse(new File(cfgFileName));
cfg .getDocumentElement ().normalize ();
} catch (Exception e) {
e.printStackTrace();
In the above code I am parsing the xml file and i am doing schema validation. Schema validation is proper and it is validating correctly. Only problem is that, It is validating and showing error correctly correctly but it is not catching that error.
For clear understanding I am printing one statement before parsing and after parsing.
SYSTEM.OUT.PRINTLN("Vijay .. code .. damar\n") this is before parsing
SYSTEM.OUT.PRINTLN("Vijay .. code .. success\n") this is after parsing
Here what is happening means, It is validating correctly and showing error :
[Error] nw_layout-new.xml:800:97: Datatype error: Value 'y' does not match regular expression facet 'yes|no'..
Vijay .. code .. damar
Vijay .. code .. success
Here it is showing error and still continueing not catching.
Plz give solution for this.
Thanks

FloodFill Not working with transparent BirmapData, Plz. help...

Hello friends,
I hav a movie [instance name : myObject] clip with some pattern design in it. Now i hav converted it to Bitmap to use FloodFill method on Runtime.
code in which The floodFill not working:
Code:
var bitmapData:BitmapData = new BitmapData(350, 450, true, 0x00FF0000);
bitmapData.draw(myObject);
var con:Bitmap = new Bitmap(bitmapData);
con.smoothing = true;//turn on smoothing
addChild(con);
con.x = myObject.x;
con.y = myObject.y;
// and called following floodFill function on a button click event
bitmapData.floodFill(myObject.mouseX, myObject.mouseY, 0x00FF0000);
code in which The floodFill working
Code:
var bitmapData:BitmapData = new BitmapData(350, 450, false, 0x00000000);
//Next lines as above
i hav set the transparency to false, it Works. But i hav a object in background that i hav to keep visible to user.

Hey miah-hamid,
Welcome to the BlackBerry Support Community Forums.
Thanks for the question.
Do you have a BlackBerry data plan with your network service provider? I would suggest connecting to a Wi-Fi network and then wait for the BBM Setup screen to finish.
Let me know if the issue still persists after 15 minutes.
Cheers.

hi
iam working on a finance report
where there is a need for opening balance and closing balance colum, i have designed the column the out put comes but the prob is after displaying the opening balance closing balance it again displays a nil opening balance and closing balance for all the values given as input
its liek this
opening balance=0.00
closing balance=0.00
i have attached the formula which i have written pls help me wats wrong in the formula column
for opening balance
function CF_total_dr1Formula return Number is
begin
IF :cf_total_dr - :cf_total_cr > 0 THEN
RETURN(:cf_total_dr - :cf_total_cr);
ELSE
RETURN( 0 );
END IF;
end;
similarly for closing balance too

cf_total_dr is again calculated using a formula.. similarly cf_total_dr
i have specified the formula below, again this debit balance is a formula column
function CF_total_drFormula return Number is
v_bal NUMBER;
BEGIN
v_bal := debit_balance(:p_from_date);
RETURN(v_bal);
END;

I use firefox 8.d older versions,by default,hd a feature tht enabled SMART KEYWORD searches.i did nt hv 2 SET KEYWORDS.4 example,typing UTUB in d address bar wd open YOUTUBE.its not happening with this version.plz help me get those settings back.

''duplicate = locking - https://support.mozilla.com/en-US/questions/897627''
more examples..
typing GOOGLE LANG in the address bar wd take me to GOOGLE LANGUAGE TOOLS.
SGS SE in the in the address bar would take me to SGSSTUDENTBOSTADER.SE.
even WRONGLY TYPED or truncated keywords would take me to a proper and logical URL as a result. for example, GAMIL used to take me to GMAIL.
i did not have to set ANY KEYWORDS. this feature was there by DEFAULT. PLEASE help me restore it. it is frustrating to type the whole url.

You have used character data somewhere it is not permitted to appear. Mistakes that can cause this error include:
* putting text directly in the body of the document without wrapping it in a container element (such as a <p>aragraph</p>), or
* forgetting to quote an attribute value (where characters such as "%" and "/" are common, but cannot appear without surrounding quotes), or
* using XHTML-style self-closing tags (such as <meta ... />) in HTML 4.01 or earlier. To fix, remove the extra slash ('/') character. For more information about the reasons for this, see Empty elements in SGML, HTML, XML, and XHTML.
thanks in advance...

one more thing...the code runs properly on localhost... i tested it on my pc n it was fine..both in firefox and IE...
i guess there is a specific syntax i need to follow (strict syntax) but i dunno what it is...:(
