How to Program 6020E in VC++

Hi,
I've a 6020E connected to my laptop working on Windows XP Pro. I also have the software that came with it installed on my machine.
I do not have either Measurement Studio or Labview on my system.
Please let me know the methodology to program and access this device in my VC++ application. Also, name of libraries, dlls or OCXs will be useful.
Thanks

Teddybare,
Since the DAQPad-6020E is not supported by NI-DAQmx, you will need to use Traditional NI-DAQ to program this device. Numerous Traditional NI-DAQ examples for use in VC++ are available in the following location:
C:\Program Files\National Instruments\NI-DAQ\Examples\VisualC
Additionally, the following KnowledgeBase explains how to use these examples in VC++:
KnowledgeBase: How to Compile and Run NI-DAQ Examples with Microsoft Visual C++
Finally, the Traditional NI-DAQ Function Reference Help provides documentation for all of the Traditional NI-DAQ functions. This resource is available in the following location:
>Start >> Programs >> National Instruments >> NI-DAQ
Good luck with your application.

How to program a midi foot controller on Mainstage? Does anyone knows how to program the foot controller with exclusive solo channel in order not to dance "tip tap" while from clean guitar I go to crunch or solo? How to do this programming on Mainstage?

How to program a midi foot controller on Mainstage? Does anyone knows how to program the foot controller with exclusive solo channel in order not to dance "tip tap" while from clean guitar I go to crunch or solo? How to do this programming on Mainstage?
I basically managed to learn how to invert parameters which allows me to be as default in the clean guitar channel and if I switch the first button on the midi foot controller I switch to crunch, but at this point I tryied so hard to programm the second and third button to switch, only through a button in one step, to a third channel for distorsion or a 4th channel for solo guitar but I couldn't figured out how this work can be done!
I would appreciate if anyone could help or share this experience with others who are experiencing the same problem.
Cheers.

I cannot seem to get mainstage to recognize my FCB either. I am using IFCB. Anyone figure this out?
Thanks,

How to program mails to be sent in future date

hi
i would like to knwo how to program my mails to be sent in a future date.
in the mail application and Outlook for Mac.
(outlook for windows allows me to program de date a mail may be sent)
best regards

You can use the Automator app to set an alarm on your calendar which sends the mail at a future time.
It's simpler than it might sound. This explains how:

I want to send 10 bit ADC from PIC via serial communicaton. i send it separetly 8 bit first then the other 2 bit. how to program in labview to capture those two packet then combine it togother

i want to send 10 bit ADC from PIC mCu via serial communicaton.
i send it separetly 8 bit first then the other 2 bit (2 bit --> with zero at 6 bit from LSB).
how to program in labview to capture those two packet and then combine it together
so i have 10 bit in lab view
thank you

Close, but now quite. You need to specify to the VISA Read how many bytes to read, not how many bits. Thus, the input would be 2, not 16. It's also not clear why you're trying to use the "String to Byte Array". The Type Cast will give you a number based on what data type you wired. You're basically telling it how to interpret the string. In this case we're telling it to interpret the string a 16-bit value, so we'll get a 16-bit integer. I know you said you wanted a 10-bit, but you can't have that. You'll get a 16-bit with 6 bits set to zero. Note: I did not completely understand what you said so we may need to change this slightly, but we want to get the communication and reading collection working first.
Also, since you seem to be setting this in a loop you probably want to monitor this or to collect the data. For that you need a shift register. See attached for a modified version of your attempt. You need to set the datatype to I16 or U16 based on whether the value you get from the PIC is signed or unsigned.

I don't know how to program my DVR to edit out the commercials

Does anyone know how to program the DVR not to record the commercials? Its not a problem on public television, of course.

Actually often very easy to do, but we will not see it again. The Industry has fought against it and made all the manufacturers remove such features.

Modify the TicTacToeServer /client from deitel How to program

We've been given example code from the deitel & deitel book how to program and have to carry out the following alterations:
a) Modify the TicTacToeServer class to test for a win, loss or draw on each move in the game. Send a message to each client applet that indicates the result of the game when the game is over.
b) Modify the TicTacToeClient class to display a button that when clicked allows the client to play another game. The button should be enabled only when a game completes. Note that both class TicTacToeClient and class TicTacToeServer must be modified to reset the board and all state information. Also, the other TicTacToeClient should be notified that a new game is about to begin so its board and state can be reset.
c) Modify the TicTacToeClient class to provide a button that allows a client to terminate the program at any time. When the user clicks the button, the server and the other client should be notified. The server should then wait for a connection from another client so a new game can begin.
d) Modify the TicTacToeClient class and the TicTacToeServer class so the winner of a game can choose game piece X or O for the next game. Remember: X always goes first.
So far I have only been able to do part a) of the exercise im having a lot of difficulty with part b) which allows the client to play a new game.The code ive done so far is listed below if anyone can help i would be forever greatful. Thanks

Subtle bug in Deitel & Deitel "Java How to Program" book

Merry x mas and happy new year, guys.
I have this applet (which is at the same time runnable and listener) its printed in Deitel & Deitel "Java How to Program" book 3rd ed.
The program works but as you turn on and off the "suspend" checkboxes some of the threads are not notified, so they go to infinite wait state, deadlock. I couldn't figure out what is wrong or how to fix the problem.. please read the code below, or copy and paste this code to your eclipse, its just one file, then play with the check boxes, some of the threads don't wake up after wait... technically they don't shift from WAITING to TIMED_WAITING state.

No, notifyAll() is used to tell the threads that we're stopping.... see that it's written in the stop() method of the applet. Eg if the user browses away from our applet we set the array of threads to null and notify them all. So notifyAll() makes sense.Yes, it does make sense there too (!!!!!!!).
However, I gave it a try with what u suggested, and it didn't work (as expected) .... Apparently you did not really read my suggestion or my explanation. If you had, you'd have expected it to work and it would have worked.
the problems still remains, some threads are getting in wait state even if their check box is not suspended.Maybe you should add the following code to understand the root cause and solution.
    System.out.println("Thread " + index + " will wait to be notified.");
    wait();
    System.out.println("Thread " + index + " was notified.");
what could the problem be?Improper use of notify()

How to program the simple tcp/ip connection?

I would like to know how to program in labview the simple tcp/ip connetion.
And is there some site with examples.

You should probably start with the examples that ship with LabVIEW. For a good
server-to-single-client example, check out Data Client.vi and Data Server.vi
from the shipping examples, and for a good server-to-multiple-client example,
try the Date Client.vi/Date Server.vi pair instead. All of these can be found
in the following VI library:
\examples\comm\tcpex.llb
or via the Search Examples interface in LabVIEW. There are certainly
additional examples on the NI site, but there's no better place to start than
with these.

I know how to program in java(Should I learn c, c++?)

I know how to program in java. I want to be able to communicate with the hardware on my pc. I also hear that C, C++ is a lower level than java. Lower level meaning it can communicate with the hardware. I know java is very portable could do interfacing and could do so many things with the java programming language. I find the java programmig language cool. Now when I read about the JNI(java native interface) I think I could communicate with methods from java to functions in c++. I want to learn c++ and use it with JNI.
Posting this topic because I want to be sure about what I'm doing.
Thanks
George

in fact, memory management is the main pitfall in C++ programming. The following may give you a few headaches:
- destructors
- header files which try to include eachother
- "memory access violation"
- templates (upcoming java includes generics, which is similar)

If you can overcome the above problems, you'll find that c++ is much like Java, only a bit more low-level. Accessing hardware directly however is quite a challenge (espescially under Windows which doesn't allow direct access for as far as I know), but not impossible. I don't know exactly, but I think it involves developing a small driver layer.
It's to bad you learnt Java before C++, the other way around would have been much easier.

How to program in java

hey guys. i am an undergraduate student. graduating next spring 2007. i did all my programming languages which were required in my course in 2004 and since that i have not taken any programming classes. i got my internship as a database administrator so got into MSaccess and Sql and VbA scripting. since my graduation year is near i want to be strong in database and programming and i was just reading about the employers what kind of programming they prefer and most of the times out of 100 you can say 80% needs java. so i have realized if i have my skills good in java and database job wont be any problem. i would like you to tell me about books i can buy from amazon.com or resources on internet from which i can understand the concept of programming again and then once my concept is clear about all the data types and functions i can start learning java. i would like you to tell me good java books also and some advance. the only book i have is the second edition of Java how to program. Thanks alot for all your help.

How to program in Java to delete a ZipEntry in ZipFile

As we all known we can delete a zipentry in zipfile easily using WinZip,but how to program in Java to delete a ZipEntry in ZipFile? I can not find API function in ZIP package.Please help me,thanks.

I think there are no methods to delete a particual file from a zip file -
maybe there are packagers for that but not in java.util.zip
you can just write your own function uncompress - and create a new file again - you can look here to get some examples

Deitel, Java How To Program exercise question

Hi, :)
I'm new to programming and I'm using the Java How To Program Fourth Edition from Deitel and Deitel as my text. I've run into a problem with Exercise 2.16 Where I'm asked:
"Write an application that asks the user to enter two numbers, obtains the numbers from the user and prints the sum, product, difference, and quotient of the numbers."
From that I have written this code:
// Exercise 2.16
/* An application that asks the user to enter two numbers, obtains the numbers from the use and prints the sum,
product, difference and quotient of the numbers. Using the techniques shown in Fig 2.9 */
//Java extension packages
import javax.swing.JOptionPane;
public class Exercise2_16{
     //Main method
     public static void main(String args[]){
     String firstNumber, secondNumber;                          //introduce variables
     int number1, number2, sum, product, difference, quotient;          //introduce variables
     firstNumber=JOptionPane.showInputDialog("Enter first integer:");     //Create input window
     secondNumber=JOptionPane.showInputDialog("Enter second integer:");     //Create input window
     number1=Integer.parseInt(firstNumber);                         //String to integer
     number2=Integer.parseInt(secondNumber);                         //String to integer
     //perform operations
     sum = number1+number2;
     product = number1*number2;
     difference = number1-number2;
     quotient = number1/number2;
     //Display results
     JOptionPane.showMessageDialog(null, "The sum is " + sum,
     "The product is " + product, "The difference is " + difference,
     "The quotient is " + quotient, "Results", JOptionPane.INFORMATION_MESSAGE);
     //End program
     System.exit(0);
     }//End main method
}//end class Exercise2_16
When I compile this code I get an error and I can't figure out why. Any help is really appreciated as I'm stumped and given the simplicity of the app I'm kinda bummed it has me stuck :(.

I substituted your line and this is the error I'm receiving now:
F:\jdk1.3\Learning Java>javac Exercise2_16.java
Exercise2_16.java:32: unclosed string literal
JOptionPane.showMessageDialog(null, "The sum is " + sum + ", The product is" + product + ",
The difference is" + difference + ", The quotient is" + quotient + ", \"Results\", JOptionPane.INFORMATION_MESSAGE);
^
Exercise2_16.java:35: ')' expected
System.exit(0);
^
2 errors
It doesn't really matter to me if there are returns but maybe for readability there should be and so I learn how to as well.

How to program this in java? Please help

How to program this in java?
please explain steps, it has to come out like this:
example
input: 3b1w3b
output:
BBBWBBB

import java.io.*;
public class Test {
static java.io.PrintStream o = java.lang.System.out;
public static void main(String[] args)throws Exception {
     BufferedReader BR = new BufferedReader(new InputStreamReader(System.in));
     System.out.print("Enter plot for printing: ");
     String s = BR.readLine();
     char[] cs = s.toLowerCase().toCharArray();
     for(int i=0, j=0; i < cs.length-0x1; i+=0x2, j=0)
          while(j++ < (int)(cs[i]-0x30))
               o.print((char)(cs[i+0x1]-0x20));
I tried changeing it to this so I can enter my own string, but I want to change it some more so that it can enter multiple input separated by space, so that it can form a sort of picture line by line. I tried using tolkenizer but I get errors. I dont know how to use tolkenizer properly can anyone please TEACH. you dont have to tell how or give me the code if you dont want to. yes I know Im a noob and I dont know java as good as everyone here, If everyone thinks I don't deserve help then DON'T help, I'm just trying to learn programming
