How can I acquire and record pre trigger samples

Hi I would like to acquire and record pre trigger samples. I have used many different methods including:
http://digital.ni.com/public.nsf/allkb/9DE9E3E4DAD9EE93862579C60018B6EA
the problem is I would like to acquire pre trigger samples before start trigger not reference trigger. I think reference trigger is used for stop triggering not start triggering. Could you please help me on this
Thanks?

Hi tintin_99,
I hope you are well and thank you for posting your issues to the forum.
I wanted to ask you some further information in regards to your application:
- What version of LabVIEW do you have?
- What operating system (OS) are you running on your PC/laptop?
- Which application programming interface (API) are you using? NI-DAQmx, NI-Scope?
When you mention you want to acquire the pre-trigger samples before the start trigger and not the reference trigger, how are you currently doing this? Would you be able to post up your code so that everyone can have a look at it?
Here are some further links to look at:
- Continous Analog Input Acquisition with Pre-trigger Scans using 2 E-series Boards
- How Can I Acquire Pretrigger Samples with NI-SCOPE?
- Software Analog Trigger with Pre-Trigger Samples
- Synchronized Analog Input/Ouput with an Analog Trigger and Pre-Triggered Samples
I hope this is alright for now.
Kind Regards,
Dom C

How can I collect and record data in LabVIEW from Sensirion Temperature/Humidity Sensor connected to myRIO?

The product documentation of the sensor and the datasheet is attached. Also Digilent MXP Breadboard's image is attached.
I've connected the sensor to myRIO using the starter kit's MXP breadboard: http://www.digilentinc.com/Products/Detail.cfm?NavPath=2,842,1216&Prod=MXP-BB
The output of the sensor is in digital. My initial goal is to get digital output in form of 8 or 12 or 14 bits and then convert them to decimal numbers and record them.
Pin 1 of sensor is Data, which is connected to myRIO's connector A, DIO1 pin 13.
Pin 3 of sensor is Clock, which is connected to myRIO's connector B DIO5/SPI.CLK pin 21. According to the datasheet of the sensor, if VDD < 4.5V then Clock should be set to 1MHz.
Pin 4 of sensor is Ground, which is connected to Digilent MXP Breadboard GND pin.
Pin 8 of sensor is VDD, which is connected to Digilent MXP Breadboard +3.3V pin. Supply voltage range is 2.4-5.5V and recommended voltage is 3.3V.
I need to be able to send the following commands to the sensor from LabVIEW.
Measure temperature: 00000011
Measure relative humidity: 00000101
Then, myRIO has to wait for maximum 20 milliseconds (ms) for 8-bit measurement, 80 ms for 12-bit measurement, and 320 ms for 14-bit measurement.
Two bytes of measurement data will then be transmitted. myRIO as microcontroller must acknowledge each byte by pulling the DATA line (pin 13) low. All values are Most Significant Bit (MSB) first. Note that for 8-bit result, the first byte is not used. Finally, myRIO has to terminate the communication after the measurement data Least Significant Bit (LSB) has been received by keeping ACK bit, which is the LSB bit, as high.

How can I publish and record video stream in h.264 format

I'm a fresher. I want to publish and record video stream in h.264 and audio stream in AAC format .
Does flash player support to publish video stream in h.264 format ?
And which version of flash player and FMS could implement this function ?
Thank you very much.

The Flashplayer does not support h264 or AAC publishing. The Flashplayer supports only h.263 (sorenson spark) video, and Nellymoser Asao and Speex audio.
If you want to publish h.264 you'll need to use Flash Media Live Encoder, or a third party encoder.

HOW CAN I ACQUIRE AND DEPLOY DATA IN REAL TIME WITH DAQ 6024E?

HI ENGINEER,
I'M PROGRAMING AN APLICATION WHICH I NEED ACUIRING AND DEPLOYING AN ANALOGOUS SIGNAL IN REAL TIME.
I HAVE:
LabVIEW 7.0
WINDOWS 2000
DAQ CARD 6024E
THE SIGNAL I WANT TO ACQUIRE IS 0-10 Vcd FROM A SENSOR, THE PROBLEM I HAVE, IS THAT I AM ACQUIERING THE DATA AND IT SEEM THAT THEY ARE UPDATING EACH SECOND, BUT I HAVE BEEN MOVING THE PARAMETERS SUCH AS TASK TIMING IN THE DAQ ASSISTANT VI AND NOTHING HAPPENS.
CAN YOU TELL ME WHICH PARAMETERS I HAVE TO MOVE TO AQUIRE AND DEPLOY DATA IN REAL TIME

Hi barron,
If you want to see the data update quicker, you can decrease the value in the "Samples to Read" field of your DAQ Assistant. This number controls when data is transferred from the DAQ buffer to the PC. If the sampling frequency remains the same, but this field decreases, it means the buffered data will be returned more quickly.
Hope this helps.
Thanks,
Lesley Y.

Oracle Trigger - How can I capture and correct on the fly ORA-01847

Oracle Trigger - How can I capture and correct on the fly ORA-01847 day of month must be between 1.
I have a table that has a date column. Sometimes an invalid date is passed and I'd like to capture and initilize the incoming value to null and have it inserted without error. Currently I get ORA-01847 day of month must be between 1.
Example:
create table ep1
col_1 number,
col_2 date
Now if a user does the following, I want no error to occure but rather for the date value to be set to null and inserted.
insert into ep1 values('1', '41-JAN-13')
The insert may come from any client and I can't change the calling code hence can't used a precedure to replace the insert. I'm guessing there is some way to catch system level exceptions on the DB level. This doesn't need to be nice, it just needs to work.
Here is the question on experts exchange. I'm told there is no way, but there must be. After all the exception is on a DB system level and I would think one could extend or override these, or disable them.

How Can I Attach and Link an XML file to a 3D Model in a PDF?

How Can I Attach and Link an XML file to a 3D Model in a PDF?
What I am trying to do is find out how to have a 3D model and a parts list linked to it within the PDF file. I would also like to be able to add to the parts list if at all possible once the pdf has been created. A template to create future PDF's with the 3D model and list might also be useful.
I am not entirely sure if this is all possible within a PDF file, but I have viewed a PDF (Adidas Trainer) example which has a Excel file attached to it which links to the 3D model. I have also had a look at partner products such as Lattice, Tetra4D, Anark, which can do animations and all sorts, but frankly it seems a bit overkill for what I am looking to do.
Please, any help would be appreciated. Thanks

I wrote about it while ago, let me paste the whole thing.
This example has simple
buttons which upon click go to new sites and in the same time
place record in form
of *.SOL file on user drive. That record is read when you hit
the next button and
based on that the button will be selected as the one last
clicked.
You could use the very same thing just instead of suppressing
button simply gotoAndPlay frame
to continue the part you need.

How can the symbol and non-English diacritical marking, etc accessed with combinations of letters and functional keys prior to Snow Leopard be achieved in Snow Leopard?

How can the symbol and non-English diacritical marking/punctuation pallet, available in pre-Snow Leopard OSes with various combinations of letter or number keys and functional keys, be accessed in Snow Leopard? Those pre-Snow Leopard versions worked on the fly as one was making text in any pedestrian application and its native font (Mail, Text Edit, for example). One didn't need to dig around in font libraries, change font preferences, etc.

> One didn't need to dig around in font libraries, change font
> preferences, etc.
It hasn't worked like that since the Early Chalcolithic (ie, System 7 or thereabouts).
You've already got plenty of answers. Briefly (and grossly oversimplified),
- Mac OS X conforms to a standard known as Unicode; in its current incarnation, it defines over 100k characters.
- A keypress is translated into a character according to the current keyboard layout.
- The graphic representation of a character (ie, glyph), is provided by the current font.
- If a font lacks a glyph for the requested character, either another font will be automatically chosen (Mac OS X text engine), or some form of feedback (empty box, question mark, etc) will be used.
- To inspect the actual key codes, use a utility such as Key Codes.
- To inspect the current keyboard layout, invoke Keyboard Viewer.
- To inspect the full complement of glyphs of a font, invoke Character Viewer (also accessed with the Special Characters command).
(Remember that both these utilities are resizable and zoomable -- you can enlarge them to a comfortable viewing size, then zoom out to see more of the screen for your original task.)
- For a more detailed look, use a utility such as UnicodeChecker.
- The default keyboard layout depends on your Mac OS X localisation.
(Keep in mind that there's no need to stick with the default layout; choose whichever one makes sense to you, given your language, habits, and proclivities. Mac OS X comes bundled with quite a few, including some obviously designed for the huddled masses of refugees from the Dark Side, who, in their wretched ignorance, have the unmitigated gall of labelling our native ways "really uncomfortable". Oh well, this, too, shall pass.
If none of the supplied keyboard layouts fits your needs -- if, for instance, you write your emails in Etruscan -- go out on the 'net, you'll find quite a few. Or write your own with Ukulele, it's not really all that difficult.)
- Use Keyboard Viewer to familiarise yourself with the current layout and to enter the odd character; but, to be proficient, you should learn your layout to the point that KV is no longer needed.
- Use Character Viewer to enter the odd character not available in the current keyboard layout.
Neither Keyboard Viewer nor Character Viewer are effective tools for more extensive needs, eg, for writing and editing bilingual or multilingual texts. In such a case, you should enable the respective keyboard layouts and switch between them with a keyboard shortcut.
A few interesting layouts bundled with Mac OS X have already been mentioned. Let me add three.
- Dvorak: several layouts based on the Dvorak keyboard. It is claimed that the latter is more productive and lessens RSI risk.
- US Extended: based on QWERTY, it offers a more extensive set of diacritics (eg, caron, breve) via dead keys.
- Unicode Hex Input: also based QWERTY, it allows input by Unicode codepoint (in hexadecimal), so it's the most extensive layout of all; eg, to enter the character "Parenthesized Number Twelve" (U+247F), hold down Option, type "247f", release Option.
