How to grab a certain number of bits

hi,
I have a 32 bit number, and I want to grab the second byte only, so from:
00001000 00000000 01001011 00100101
I want my variable q = 01001011, how do I do this?
many thanks, Ron

Hi, hmm, I still seem to be getting an error though (or a value that I am not expecting!).
So this is what I am doing:
q = (m_d2.getCardIntVal(j)>>>8)&0xFF;
r = (m_d2.getCardIntVal(k)>>>8)&0xFF;
s = q|r;
System.out.println(...Ok, it seems fine, but when I examine the values I get this (printing out the output):
Three of Spades 17 Ten of Spades 24 combined value = 25
10001 11001
Three of Spades 17 Jack of Spades 25 combined value = 25
10001 11010
Three of Spades 17 Queen of Spades 26 combined value = 27
10001 11011
Three of Spades 17 King of Spades 27 combined value = 27
10001 11100
Three of Spades 17 Ace of Spades 28 combined value = 29
10001 100000
Three of Spades 17 Deuce of Hearts 32 combined value = 49
10001 100001
Three of Spades 17 Three of Hearts 33 combined value = 49
Is it because something is happening when the values are being | together because they are of different sizes?
What I am doing is going through the deck generating all the 2 card combinations, and trying to generate a distinct value for each pair type, for example any suited jack/queen combination should generate the same value, whereas an an offsuit jack/queen would have a different value. Anyway, I just don't get why the three of spades, and deuce of hearts pair give me a value of 49, and so does the three of spades and three of hearts combo!
This is getting annoying! Many thanks, Ron

How to display a certain number of channels...

Hi!
I am using LabVIEW 8.5 and I am trying to display a certain number of channels using multiple channels ...
I can display them in a graph, but I am displaying the 16 analog input channels
that NI 6024E have and I need to display only the channels that have something
connected to them (I do not know which channel will have something connected to
it). If they have a signal (temperature), I will like to display that channel/s in a graph and save that channel/s in a txt file. If not
I do not want to show or save the channel/s.
How can I do that using DQA Assistance?
I am able to do all this using one channel, I can display in
a graph, I can save it in a txt file, but I am not able to do it for n number
of active channels only. Any advice or suggestion will be appreciated.
Sincerely,
Julieta.

Hi,
I am trying to give the user the opportunity of selecting how
many channels he/she want to connect to the board… Now I only have two channels and I know what
those channels are, but I want to do something that allow the user to select
the channels that he/she needs (maybe the 16 or maybe only 3 or 7). I saw that
in older versions of Labview there exists in Analog Input a “AI MULT PT” that
maybe could allow me to input there specific channel (I am using 8.5 version of LabView).
I am doing this to detect the channels, but it is not even
close of how it supposes to be, because the user can not select… I just want to
display the channels the user select and calculate the mean only for those
channels.
Any suggestion advice will be appreciated…
Sincerely,
Julieta.
P.D.: My English is not so good…

How can i find a total of minutes from and to a certain number

I need to track the amount of time to and from a certain number on my cell phone. How do I do that?

Log in, as klue said, and once you are viewing the details for the line, click the heading of the column where the phone number is listed. That should sort the column, so all the calls to and from that specific number are at least grouped together, making it easier to add up.
You can also download all the details to a spreadsheet, and depending on your Excel skills, pull the data out and total up the minutes.
If you are looking for a button or other quick tool to get the info, it isn't there. You have to manipulate the data yourself.

How to get checkbox checked when sum equals a certain number

I have created a spreadsheet with 25 rows that will have numerical entries. How do I put in a checkbox that becomes checked once the sum of the numbers Un that row equals a certain number?
Thanks in advance.

A hack would be to use CHAR. You have thousands of symbols to choose from. I scanned through some and found a check (there are many more which might better fit your needs).
So, if your numbers are listed in B1:B25 and 100 is your magic number, then:
=IF(SUM(B1:B25)=100, CHAR(10004), "")
or something like:
=IF(SUM(B1:B25)=100, CHAR(10004), CHAR(10063))

How do I send out a certain number of pulses

I am using the E-Series DAQ board, and in my programing I have three stages, I need to send out a certain number of pulse depending on the stage selected. For example if stage one is selected 30 pulses will be sent out and thats it. The pulses will be used to move a stepper motor. The stepper motor is a linear stepper so the pulses will be used to move the shaft 1 inch or 3 inches, depending on the stage selected.

It sounds like you want to generate a "Finite Pulse Train". Depending on which programming language you intend to implement this with (LabVIEW, LabWindows/CVI, Measurement Studio for Visual Basic or C++), we probably already have an example written. From our website at www.ni.com simply search for Finite Pulse Train. You will want to only use examples that have been written for the DAQ-STC chip, which our E-Series DAQ devices leverage.
The finite pulse train examples will show you how to output a finite pulse, of say 30 pulses, as well as configure the frequency and duty cycle.

Use hardware to generate a certain number of pulses using PXI-5652

Is it possible to generate a certain number of periods (turn on the output for a predetermined amount of time using hardware with micro-second resolution) using the PXI-5652.

Hello Matt,
If you had a Vector Signal Generator, this would be more controllable using something similar to this forum.
Otherwise, the only way to control time on the 565x would be to use OOK modulation scheme. This will allow you to turn on the signal for a little time On and Off.
There is a shipped example called "565x Digital Modulation.vi" (on versions 1.3 and later of the RFSG driver) that can perform this task. Basically it uses the function named "niRFSG Configure Digital Modulation User Defined Waveform.vi" to write the user bit sequence and with property nodes you will configure the OOK scheme and the symbol rate (refer to specifications of your card for the possible values).
Hope this helps,

Hi Memalyn
Essentially, the bare issue is that you have a 500GB hard drive with only 10GB free. That is not sufficient to run the system properly. The two options you have are to move/remove files to another location, or to install a larger hard drive (eg 2TB). Drive space has nothing to do with SMC firmware, and usually large media files are to blame.
My first recommendation is this: download and run the free OmniDiskSweeper. This will identify the exact size of all your folders - you can drill down into the subfolders and figure out where your largest culprits are. For example, you might find that your Pictures folder contains both an iPhoto Library and copies that you've brought in from a camera but are outside the iPhoto Library structure. Or perhaps you have a lot of purchased video content in iTunes.
If you find files that you KNOW you do not need, you can delete them. Don't delete them just because you have a backup, since if the backup fails, you will lose all your copies.
Don't worry about "cleaners" for now - they don't save much space and can actually cause problems. Deal with the large file situation first and see how you get on.
Let us know what you find out, and if you manage to get your space back.

How do I limit the number of rows retrieved at a time using RefCursor?

I have a PL/SQL package in use, that returns a REF CURSOR. This is currently being used in a Forms 6i application. Now I want to develop an ASP.NET web application that displays exactly the same information as my Forms 6i module. In fact those two applications will be used concurrently for a while.
I looked at the sample code provided on otn.oracle.com and decided to use the OracleDataAdapter.Fill()-method to fill a dataset and bind that dataset to a pageable GridView. Now I wonder, whether this method retrieves ALL records of the query at once and how I can limit the number of rows fetched? The Select statement retrieves up to 10000 rows at a time. Most of the time, a user is only interested in the first 20-30 rows. Forms 6i fetches more rows as the user scrolls down, how can I implement the same behavior in ODP.NET?
- Markus

Excuse me, but the reply does not quite answer my question. Maybe I did not explain my concerns clear enough:
I understand the use of the two properties (RowSize and FetchSize) to reduce the amount of round trips needed to transfer the data - not the number of rows fetched in total. This would still lead to a situation where all rows are transferred, when I am using the OracleDataAdapter.Fill()-Method. Is this correct or did I misunderstand the function of this method?
I quote the otherwise really helpful article you send me:
Of course, there is a cost if the fetch size is arbitrarily large. More client-side memory and processor cycles will be needed to store and manage a larger amount of data. The goal is to find a high-performing balance between the number of round trips and the amount of data retrieved per trip.
My RowSize is for sure a bit larger than the one in the given example. The query will probably be used by up to 100 users at a time, so I would like to limit the resource-costs not only on the network by the number of round trips, but also on the web-server which is storing all these records in it's memory per user-request.

Oracle Linux behaves exactly like Red Hat in this matter an /proc/cpuinfo can be used for that. I guess this is because you have set up VirtualBox to only assign one virtual CPU to your guest Linux.

How to default an address number delivery address in the PO item

Hi All,
I have some combination of certain Material / Vendor / Delivery address.
I have created some address numbers from transaction MEAN.
I can successfully assign these in PO detail manually. Then the address gets updated from it
for plant or storage location if specified.
What I need to know is how to "default" this address number in the PO detail.
I couldn't fine appropriate field in info record, but I have a feeling that it should be possible.
Could anyone help me on this please?
Thanks,
ATO

Hi Nadia,
Thank you for your reply.
The plan is that storage location gets default on the PO by material master setting.
I have configured the storage location address, so this defaults in the delivery address tab.
This storage location is our warehouse to receive goods.
Sometimes we delivery goods directory to the vendor without receiving into the warehouse.
In this scenario, we are using the address number to print the vendor address on the PO output.
The combination of material and vendor is unique when we need to deliver directory.
So the expectation is to default this address number in this certain case.
Do you mean this will be possible without user exit?
Thanks,
ATO

How to use a random number equal another number. (with my source code)

hi, i'm having trouble with this assignment.
3. Determine how many times a die must be rolled in order to
win a prize. (This represents one trial.) Print this value to a
text file.
4. Conduct at least 1,000 trials.
5. Read the data back in from all of the trials.
6. Calculate the average number of times a die must be rolled in order to win a prize.
7. Print the result to the screen
This is what I have so far.
But I get a "int cannot be dereferenced" error
* Write a description of class BottleCapPrize here.
* @author (your name)
* @version (a version number or a date)
import java.io.IOException;
import java.io.PrintWriter;
import java.util.Scanner;
import java.util.Random;
import java.io.File;
public class BottleCapPrize
public static void main (String [ ] args) throws IOException
PrintWriter outFile = new PrintWriter(new File("bah.txt"));
Random randomGenerator = new Random();
int random = randomGenerator.nextInt(5);
int count = 0;
for (int loop = 1; loop <= 1000; loop++)
if(random.equals("3"))
outFile.println("Congratulations, both pairs matched.");
count++;
outFile.close ( );
}

And the random generator can only choose a 1 or 2 or 3 or 4 or 5. This is then randomly chosen 1000 times like 400 2s and 200 5s for example.I think you have still to appreciate that the task is not to roll a dice 1000 times and see how many of each number you get.
Tackle it one step at a time:
3. A - Determine how many times a die must be rolled in order to win a prize. (This represents one trial.)
B - Print this value to a text file.
Even the first part of the problem can be broken down into two parts. I strongly suggest to get step 3A working correctly before you move any further. Notice that this step does not involve 1000 rolls of the dice. Rather it asks you to roll the dice as many times as needed until you get a three. Start there: write a method that does no more than report the number of times it had to roll the dice in order to get a three.
import java.util.Random;
public class BottleCapPrize
    public static void main (String [ ] args) throws IOException
        Random randomGenerator = new Random();
        int count = 0;
         * Your code here.
         * At the end of it count should be equal to the number of
         * dice rolls it took to get a three.
        System.out.println("It took " + count + "dice rolls to get a three");
}Once you have this method working correctly - that is you run it lots of times and it agrees with what you find experimentally with an actual dice - then you can move on to saving this result to a file (step 3B). The steps of the assignment provide a framework that makes sense - follow them one at a time.
but only thing is that the random number is all a certain number.That's a fairly major defect in a randomly generated number ;). Read the API documentation for the [nextInt(n)|http://java.sun.com/javase/6/docs/api/java/util/Random.html#nextInt(int)] method. It should be clear that this is the method that randomly generates a number. So if you want lots of randomly generated numbers (rather than one randomly generated number lots of times) then you have to call this method lots of times. A call to nextInt(n) is the programming equivalent to rolling a dice.
