Thread pool small example needed

Hi friends,
Can you please give a small example program for thread pool to understand?

>
Can you please give a small example program for thread pool to understand?>I don't know (whether you would understand an example - simple or otherwise).
But why don't you help dispel the impression that you are just another lazy student, by making a start on some code, then asking a specific question, when you get stuck?

How can I get information of the switched channel in an example program from NI?

When I use the example program "niSwitch DMM Switch Synchronous Scanning.vi", I'am not able to get any information, wich channel is active. Wich block has to be used and how must I connect it to see this.
The other one is, that te sytax for the scan list, described in the help does not switch through the channel, how has this to be modified?
Im using a SCXI 1128 in Slot 8 of a 1052 combo chassis and the DMM is a PXI 4070 in the Slot 2.
Attachments:
niSwitch DMM Switch Synchronous Scanning.vi ‏145 KB

Bigmatzeman,
finally, i got a working solution which should suite you!
Ok, here is what you have to do/what is missing in your setup:
First, you can leave the modules as they are already inserted in your chassis.
Second, you will need a special AUX-cable to synchronize the DMM and the switch. You can find infos on that here
in the section "Single Module Scanning". Connect the cable between the
DMM and the front connector of the switch (1331, scanadv. and
externaltrig.)
Third, i advise you to use the HV8-BAN4-cable to connected the signals
to your DMM. This is because the cable is specified for the appropriate
voltage the DMM and the switch are capable of (300 V). The connection
of the HV8 can be done in the 1052 above the PXI-slots.
And at last, open the example "niSwitch DMM Switch Handshaking.vi", set
the devices to the appropriate identifiers. Select for both triggers
for the DMM "External" and for both triggers of the switch "Front
Connector". Change the Scanlist to "ch0:5->com0;". If you are using
the HV8-BAN4 instead of direct front connector-connection, you have to
change the code a bit, too: insert a "niSwitch Connect Channels" VI in
front of the "niSwitch Configure Scan Trigger" which connects "ab0" and
"com0".
Ok, now the example should work correctly and you should be able to use all other SCXI modules together with your 6281.
Hope this helps,
Norbert
[Edit]: My setup was 4072, 6052E, 1127 and 1011 (instead of 4070, 6281,
1128 and 1052 as you do). But that should work just the same way.

How to get rid of the "time out" when using DAQ AI in the example program

I try an example file called "AcqVoltageSamples_IntClkDigRef" (Visual C++ .NET). It works great. However, if the program has not recieved the data, it sent out a timeout message. How to get rid of the "time out"? I cannot find anywhere in the code. Is this a property I have to reset somewhere else?
Thank you,
Yajai.

Hello Yajai,
The example program will use the default value for timeout, 10 seconds. To change this, you will have to set the Stream.Timeout value. I inserted this function into the example and set it equal to -1, and the program will wait indefinitely for the trigger signal without timing out. Please see the attached image to how this was implemented.
I hope this help. Let me know if you have any further questions.
Regards,
Sean C.

How to install "Compact FieldPoint Embedded Data Logger Example Program" on cfp2200

i finally managed to get max to see the devices of my cfp2200.
(i had to disable every unused networkadapter due to overlapping subnets)
now i want to deploy the example programm "Compact FieldPoint Embedded Data Logger Example Program"
http://zone.ni.com/devzone/cda/epd/p/id/3221
i therefor have tried to install the runtime 8.5 on the target. however this is not possble, because i have labview 2010 installed and it gives the message:
"the host has a newer version available"
ok. runtime 2010 should work to - not?
i open a new project - import my *.iak-file and drag-n-drop the content of "cfp_data_logger_source.zip" onto the target.
now if i open the file cFPEmbeddedDataLogger.vi the run-button is cracked and by pressing it an errorlist opens.
the errors say stuff like:
target does not support this function/subvi
and
vi has been modified with a different applicationinstance
please help me to make this work.
i know that it is possible to get the programm to run on the cfp2200 even dough it is primaly designed for the cFP-2000, cFP-2010, cFP-2020, cFP-2100, cFP-2110,
cFP-2120.
big THANX already for you help !!!!!

Hi, thanks for your help=) I've manage to drag the file into my targeted controller. I am now doing the setting of the data logger program, but there's one thing I'm unsure of. May I know what does it mean by the cFP controller clock? http://zone.ni.com/devzone/cda/tut/p/id/3219 . Thanks. =)
Log On Startup
Start logging when the controller powers up.
Start Log Time
The time to start logging.
Stop Log Time
The time to stop logging.
Note: Make sure the clock is set correctly on the controller. The settings described above refer to the cFP controller clock.
Log Rate
The number of milliseconds to wait between each acquisition.
FP Drive For Data Files
The drive to store the log files in. The C: drive is the default for all cFP controllers. If you want to save to the removable CompactFlash drive on the cFP controller, select the D: drive.
Digital "Pause" Line
The Digital Input item to use as a "pause" button for data logging. Logging pauses when the signal is high. When the signal goes low again, a new file is created and logging continues if appropriate.
Note: Use only Digital Input items for the Digital "Pause" Line.
Tip: You can use DIP Switch 3 to block the current data from being logged. This switch works the same way as the Digital "Pause" line.
Logging Session Tag
Is stamped on the spreadsheet that the data logger creates.

I'm not sure I understand the question.
In PL/SQL, the way to pass the value of x to another variable v is:
v := x;
Here, v can be an OUT argument or an IN OUT argument. (It can be any kind of variable except an IN argument or a CONSTANT.)
PL/SQL doesn't really have any way to display values. For debugging, people often use dbms_output, like this:
dbms_output.put_line (y || ' = y inside sample procedure');
Many front end tools (such as SQL*Plus) can display the text after PL/SQL finishes.
By default, all arguments in PL/SQL are passed by value. To call by reference, use the NOCOPY hint, as shown below:
SET SERVEROUTPUT ON;
CREATE OR REPLACE PROCEDURE sample ( x IN              NUMBER
                                   , y OUT             NUMBER
                                   , z IN OUT NOCOPY NUMBER
IS
BEGIN
     y := x;
     z := x;
     dbms_output.put_line (y || ' = y inside sample procedure');
     dbms_output.put_line (z || ' = z');
END sample;

Hi,
The examples are calling a browser but that is not what we are looking for. What we are looking for is (via ABAP) to send our http request and receive back the anwser. They (http://ec.europa.eu/taxation_customs/vies/) provide the SOAP message (WSDL : (http://ec.europa.eu/taxation_customs/vies/api/checkVatPort?wsdl). My question is if it is possible witout using XI and yes how? If I understand it correctly is should be possible via ABAP (example program RSWF_TEST_HTTP), but if I create my own program I get the message HTTP-Receive: RC=400 ICM_HTTP_CONNECTION_FAILED. Maybe the ABAP code is correct, but maybe I should change some settings or configure something else.

An error of an DAQmx ANSI C example program

Hi,
I got a piece of error information when I run an example program, i.e. "Cont Acq-Int Clk-Anlg Start" of NI-DAQmx for analog input (please see the attachment for the error information). I tried my best to find the reason but I can't. I didn't change anything of that program. Could you please help me?
I don't have that problem when I try the analog output program.
Any help will be appreciated very much!

Marlon,
The code in ContAcq-IntClk-AnlgStart_main.c specifies "Dev1/ai0" as the channel to read from and "PFI0" as the trigger line. You may need to change these from the defaults to match the hardware and/or signals on your system.
Assuming that the channel and trigger line are specified correctly for your system, then it seems that a valid trigger signal is not being generated.
Note that the example uses 0.0 as the default trigger level. Depending on your specific trigger signal and possible noise on that line, your trigger signal may never cross 0.0 and therefore may never trigger the read. You could try modifying your trigger signal or the trigger level and see if that fixes the problem.
