How to design a line counter?

Here is the requirement:
a single Line Of Counter count for the source program file
separate LOC and method counts for each object along with the object�s name
Example output ,ie,count how many lines in every method, every class

Try using the Class and Method objects to find out the constructor and method names in the sourcre file. Then you will have to use
FileReader to count number of lines. I can't think of a better solution right now.

How to get file line count.

Hey guys,
How to get file line count very fast? I am using BufferedReader to readLine() and count. But when dealing with big file, say several GB size, this process will be very time consuming.
Is there any other methods?
Thanks in advace!

What I'd do is you create an infofetcher, register a listener, implement gotMore() and have that scan for '\n'
Some might suggest getting rid of the listener/sender pattern or use multiple threads to make ii faster. This might help a little, but only if your I/O is super-duper speedy.
you are welcome to use and modify this code, but please don't change the package or take credit for it as your own work.

How to allocate space for headers in reports through line size r line count

hi ,
may i know how to allocate space for a header ( we do the same for footer through line-count ( footer space ) ) through line size or line count in reports...
thanks in advance..

How to Reduce the Gate count of a Design(RTL gate count)

Hi All,
I am a newbie to FPGA design and implemetation. I have a design (H.264 Encoder) and implemented on zynq zc702 (which is having Artix7 FPGA fabric). Now we need to implement it on zynq zc706 with reduced gate count ( because we are going to add some more blocks like rate control etc.,)
How to reduce the gate count ?
Please guide me regarding this query.
Thanks,
Ramesh

Try to reduce the overall control set. Registers in the slice shares the same control set so if the number of registers in the control set do not divide cleanly, some registers may go unused.
Make sure correct DSP and BRAM blocks are getting inferred by the tool
Try to map FSM in BRAM.
Use Synthesis and Implementation level strategies.
See if any module is having high utilization and can be reduced by changing RTL: report_utilization -hierarchical -file utilization.txt

How to get logical JTextArea line count

Hi,
I would like to get the logical JTextArea line count. The existing
getLineCount method returns the line count based on "\n", which
is not what I want.
Any ideas?
Thanks,
Pin

I found the following solution in the forum and it works.
I haven't tested for all cases though...
public static int getLineCount (JTextArea _textArea)
boolean lineWrapHolder = _textArea.getLineWrap();
_textArea.setLineWrap(false);
double height = _textArea.getPreferredSize().getHeight();
_textArea.setLineWrap(lineWrapHolder);
double rowSize = height/_textArea.getLineCount();
return (int) (_textArea.getPreferredSize().getHeight() / rowSize);
Thanks,

Multiple small stories with variable line counts assigned to different editors

I have a "best practice" question for you more experienced InCopy users about what workflow you recommend for my specific issue. I am experienced in InDesign, but am a InCopy newbie. I want to make sure I'm not missing a solution because my lack of experience with InCopy may be causing me not to see the forest for the trees.
Short version: What is the best way to allow multiple editors access to each of multiple small stories separately (one story per editor), but to allow the line count of each story to be variable each week, while adjusting the rest of the stories along with it on the page (see image below)?
Details: My publishing company's workflow is on CS6 with editors working in Word, and we're upgrading to CC2014 with InCopy. We have 7 in-house editors, and all files on an in-house server. We have quick deadlines (some are 15 minutes from editor writing copy to transmitting publication to subscribers). In the example below, we have 10 sections, and I have all seven editors writing different sections at the same time. A final editor has control over fitting the final page. My INDD files to test the new workflow use an assignment-based workflow. I understand I can place each of these sections as their own story, under the same assignment, so a different editor can have them checked out. However, each section does not have the same line count from week to week. Markets with more activity will get more lines.
In our current workflow, we have multiple rough Word docs pulled into one master doc with a script, that the final editor edits to fit, so each section can be a different number of lines as long as the total is the same. Then production staff load it in. When we upgrade, we can use a hybrid workflow where the final editor just loads that final Word doc into one InCopy story and edits it to fit.
It would be great if I just didn't understand how to make the text height variable for the story each editor is typing, and auto-adjust so the next story starts below where the story above it ends, and you all had an idea how I can do it!
Thanks! Nancy

I disagree to Seshu's answer to question 1.
Correct answer of question 1 is C and not A.
Sorry I didn't find time to check the rest.
To the examinee
I wouldn't assume all answers from SDN-ers are correct if my certification exam was knocking the door! I would rather try and find out the correct answers myself from the system instead of mugging these answers without any understanding of the technology involved! Find out the answers yourself from the system...that way it will help you to understand why the answer is 'C' and not 'A'...just knowing the answer is 'C' is not good enough...one has to understand "why" its 'C' and not 'A'. Hope you get my point! Good luck.

How to Use document.Lines.SetCurrentLine

Hi there, due to an enormous amount of time spent on this issue, I thought I would share how to use the SetCurrentLine method as posted to me by SAP support:
It seems very cumbersome, as I have now to do an extra Recorset look up to get all the lines if I want to get the correct index - but at least it works (hopefully).
Daniel
SUPPORTS MESSAGE ****
the way the SetCurrentLine works is as following:
You do not have to use neither the LineNum nor the VisOrder as your
parameterfor the setCurrentLine method.
The system will use the corresponding index (starting at zero)linked to
that line when running a query on the database and sorting the lines by
LineNum.
#,,DocEntry,, Item ,,LineNum,,Price,,VisOrder
1,,11669,, A1001,,,, 600,00,,
2,,11669,, A1003,,2,, 3,00,, 2
3,,11669,, A1005,,3,, 600,00,,1
See example above, that is the result of querying the database on that
sales order and sorting by LineNum.
The order in which the items are displayed in the application is based
on the VisOrder. In this example items are displayed A1001, A1005 amd
A1003.
In order to update Item A1005 I will need to create a recordset, query
the database and then loop the recordset to find the corresponding item
and then use that index from the recordset to set the value for the
SetCurrentLine method. In the example above index 0 from recordset
points at item A1001, index 1 points at item A1003 and index 2 points at
A1005 so your code should use setCurrentLine(2) to update item A1005.
If you try to use LineNum (3 in this case) you will get an error message
as index 3 does not exist in the recordset collection ( only 3 items
with indexes 0,1 and 2). If you use visOrder 1(for item A1005) then the
system will update item A1003 as 1 is the index for A1003 in the
recordset.
END OF SUPPORTS MESSAGE ********

Hi Curtis,
Your situation sounds a little different to mine, in that I know the LinNum of the documentline that I need to update - that is what the lineNumber variable is...
To update all the rows, I guess you would just iterate through all the lines sequencially (ie starting at 0 and ending at document.lines.count:
for(int i = 0; i < doc.Lines.Count; i++)
doc.Lines.SetCurrentLine(i);
// do your thing here...
How do you know what lines you want to update??

How do I use the counter and digital signals of the 6071E while it is connected to SCXI modules?

I am contemplating using a PCI 6071E with SCXI. We have the boards (6071E), we would need the cable (I suppose SH1006868) and the SCXI system. I would like to know how would you access the counter and digital line capabilities of the board. I will be using a SCXI-1314 with a SCXI-1520 Module for strain measurements but will need to use the counter and digital lines of the board as well. Can this be done? If so, how and/or what else do I need?

I think this KnowledgeBase will answer the question for you.

How do you get word count to print at the end of a document in Pages?

How do you get word count to print at the end of a document in Pages?

Pages v5 does not provide a user assignable word count variable. With some AppleScript, and a paste operation from the clipboard, you can have locale punctuated word count in this format: 7,803 — anywhere in your document. The following AppleScript works with Pages '09 v4.3 through Pages v5.5.2 on Yosemite.
I would suggest that you copy paste the following AppleScript into your [Apple] Script Editor and save it (suggestion) wordcnt.applescript. Then, follow this with an option+Save As… and this time set the File format to Script Bundle, or Application with hidden extension — saved to your Desktop. Provided you have a Pages document open, you are then a double-click from the ability to paste your current word count into Pages.
Note: If you have Pages word count display enabled, it will automatically count your pasted value as another word which initially may deceive on true word count at the time the script was run.
AppleScript
--- copy below this line ---
property locale : "en_US.UTF-8" -- In Terminal, use the locale command to see yours
if not ApplicationIsRunning("Pages") then
     display dialog "Pages must be running to use this utility."
     return quit
end if
tell application "Pages"
    tell body text of front document
        set wordCnt to count words
        -- Don't want punctuated numbers? Remove the single quote from printf format
        set the clipboard to (do shell script "export LC_ALL=" & locale & "; printf \"%'d\" " & wordCnt)
    end tell
end tell
on ApplicationIsRunning(appName)
     tell application "System Events" to set appNameIsRunning to exists (processes where name is appName)
     return appNameIsRunning
end ApplicationIsRunning

How to design a program on paper.

how to design a program on paper.
I am planning to create a small program, I want to do some paper work before writing the first line of code, what do I do and how do I do ?
should I learn UML and do it or any other thing ?
my question is to experience programmers, what do you do before writing the code for any program ?

Most projects do very little other than collect information, process the information, and store the information.
1st - Identify what your project really is (project statement including well defined scope)
2nd - Identify resources
Data
Users
Equipment Needed
Developers available for the project
etc...
3rd - Do a reality check against your resources
4th - Aquire more resources as required or scale back project scope
5th - Get buy off from interested parites on your project definition and scope.
6th - loop back to 1 as need to attain a working definition and resources to complete the project.
(Notice: no code has been written yet--nor even thought about)
7th - Identify Data and Data Sources
8th - Define appropriate distribution of functionality across Tiers
9th - Assign teams for each or set phase of each for implementation purposes (according to project needs) Note: User Interfaces are always most complex -- assign your people accordingly.
10th - Identify data and processes specific to tier
11th - process flow models with data flow over lays
12th - design objects to implement process and facilitate data flow
13th - functionality review and buy off from clients
14th - loop back to 10 as needed
(Notice: no code yet)
15th - <here it is> code here
16th - debug (with code reviews)
17th - integrate
18th - debug (with code revies)
19th - loop back to 15 as needed
20th - alpha test (large integration)
21st - debug (with code reviews)
22nd - loop back to 20 as needed
23rd - beta and user trials
24th - user requested changes
25th - debug (with code reviews)
26th - loop back to 23 as needed
27th - user buy off
28th - project delivered
29th - wrap up and archive of documentation
30th - on going (life cycle) maintenance.
There ya go, that is about what I go through when desiging a project--the coding is a very very small part in comparison to the rest. Coding come to approximately 20% of a project.

How do I configure a counter to generate pulses using DAQmx?

How do I configure a counter to generate pulses using DAQmx?
Is says in the DAQmx C reference help
"CtrnInternalOutput—The signal at this internal terminal is where the pulsed or toggled output of the counter appears. The output of a counter pulses or toggles when the counter reaches terminal count. When counting down, the counter reaches terminal count when the count reaches zero. When counting up, the counter reaches terminal count when the counter rolls over. To configure the counter to toggle or generate pulses, use the Export Signal function/VI with Counter Output Event as the signal name."
I've tried this but can't get it to work, I may have the parameters wrong or something. The DAQmxExportSignal() function is very unintuitive to me. Here is my counter config code...
int ret = 0;
ret = DAQmxCreateTask("",&task_);
errorMsg(ret);
if (ret != 0)
throw ret;
// Configure the counter
ret = DAQmxCreateCOPulseChanTicks( task_, "Dev1/ctr0", "", "/Dev1/PFI8", DAQmx_Val_Low, 0, divider, divider );
errorMsg(ret);
ret = DAQmxCfgImplicitTiming( task_, DAQmx_Val_ContSamps, 1000 );
errorMsg(ret);
// Change to pulse mode
ret = DAQmxExportSignal( task_, DAQmx_Val_CounterOutputEvent, "/Dev1/Ctr0InternalOutput" );
errorMsg(ret);
// Start the counter
ret = DAQmxStartTask(task_);
errorMsg(ret);
The above code works fine, in toggle mode, if I just comment out the DAQmxExportSignal() part.
HELP!!!
Stefan

The problem is due to the DAQmxExportSignal call. By default, when you create a counter output pulse train task, the driver will automatically set the output of the counter to toggle when the count for each high ticks and low ticks expire. The driver also automatically routes the signal present at Ctr0InternalOutput terminal (the output of the counter internal to the device) to the Ctr0Out terminal (the I/O pin available externally). Using the line
ret = DAQmxExportSignal( task_, DAQmx_Val_CounterOutputEvent, "/Dev1/Ctr0InternalOutput" );
will tell the driver to tristate the Ctr0Out terminal and not output the signal to the external I/O pin. Using the DAQmxExportSignal function is generally only useful if you want to route the signal to some other terminal internal to the board without having the output show up on the external connector, route the signal to some other external pin other than the default pin, or if you want to have the output show up at multiple locations.
If you want to change the output behavior from toggle to pulse, you need to use the DAQmxSetExportedCtrOutEventOutputBehavior function. However, this is generally only useful if all you care about are edges (not the duty cycle of the pulse train), and you want to generate higher frequency signals. For example, with a 20 MHz timebase as the source of your counter, you can only generate a 5 MHz pulse train by default. This is because the minimum value for the low and high ticks parameter is 2 (20 MHz / 4 = 5 MHz). By changing the output behavior form toggle to pulse, you can generate a pulse train at 10 MHz since the output is now pulsing instead of toggling. However, the width of each pulse is not programmable so you will no longer have a 50% duty cycle signal. I don't remember exactly what the width of each pulse is, but I believe it's in the neighborhood of 50 - 100 nanoseconds in width. I hope this information helps.

How to control the line in--- PLAY and STOP ?

Hi,
   This is the volume control library downloaded from NI wed site .It is help for my task.
   My task is to control the line in with LabVIEW, for example STOP, PLAY and adjust volume with LabVIEW button.Though the example I see the volume control can be enablement.But I don't know how to design the PLAY and STOP button.
   I see it is similar to the volume control.There is function to control the the PLAY and STOP in the system Library-winmm.dll. I don't know whether all I think is right.I have the following serial question. How to use the function?How to understand the system Library?I can't acquire some information from it and I don't know the input and output parameter in the funcion.
   Can any one help me out please?
   I'm sorry that my English is poor.

How to design an IDOC-XI-JDBC interface

Hello Experts!
I'm looking for some guidance on how to design an interface where R/3 is sending an IDOC to XI (via IDOC Adapter Receiver), then XI transforms this data into a JDBC database INSERT action.
I want to make to make the JDBC request a SYNC interface so that I can capture the number of rows inserted into the database and do some appropriate action when the insert count returns a zero value.
Since the IDOC to XI interface is ASYNC, how do I design my link so I can redirect the JDBC response out to a different adapter?
Thanks for your help!

Varying the line count in every page

Hi All..
I want to vary the line count in a page in my report.
I have mentioned the line size n line count at the starting of the report, n it prints the same no of lines in every page but in the subsequent pages , I want to increase the line count .
How can I do that ?
Thanks.

Hi Naimesh..
thanks for the reply .
well,the code u suggested does not work..NEW-PAGE is jus a standalone command with which the line count cannot be associated.
I actually have some header details that shud only appear on 1st page , n basing on the line count all works fine on 1st page ..but on the 2nd page the header details ned not appear , so only the itab details are getting printed , so the sy-tabix value remains the same but the line count is less than the 1st page leaving some space at the bottom of the page .
And in the subsequent pages the printing takes place but from the begining of the page n also leaving more space at the bottom of the page.
I want that equal no of lines get printed each page , also leaving equal no of lines at the bottom of each page.
Hope I'm sounding clear.
Any answers ?
Thanks.
Sangeet.
