Need help choosing Software for a Slide Presentation

I'd really appreciate some advice....I need to make a slide presentation with an audio soundtrack. There don't need to be any fancy special effects as the slides transition. A simple fade in & out is all I'm looking for. All I need is for some of the slides to show longer than others (maybe 6-8 secs. vs 3-4 secs. for the rest.) There are about 250-300 slides which I have in i-photo and the soundtrack will be 4 tracks I have in i-tunes. I need to be able to burn the presentation onto a DVD once it's assembled. Will the Keynote application in i-works do this or should I use something else?
Any help would be most appreciated.
Thx in advance, Malco

Welcome to the discussion boards, malcoinc . It sounds like what you want to do would best be accomplished from within iPhoto itself, using its slideshow functionality -- I believe it has all the capabilities you are looking for, including sending the slideshow directly to iDVD once it is completed. I'd suggest reading the iPhoto documentation on this feature before considering moving to some other solution, as anything else is likely to be more complex.

I’m going to get the I Mac and since the new I Mac doesn’t have DVD drive on it I was thinking to get the Samsung SE-506AB Slim Portable Blu-ray Writer in order to burn movies from I movie do I need a special software for that since the SE-506ab comes only with windows software.. but I did check and it is compatible with apple. Can you please advise me and or let me know if I’m buying the right stuff or if there is any other blu ray that will work with the I mac as plug and play.
Thank you

This freezing reminds me of really old Macs, long ago, in the days of the old-school peripherals like SCSI drives, terminators, scanners and the like. If you had a SCSI conflict, like the wrong device ID's or something, you'd freeze up like that. Back in those days you'd call 800-SOS-APPLE (AAPL?) and they'd run you through disconnecting all your extra hardware - Jaz and Zip drives, CD burners, scanners etc and then eliminate them one by one by adding them incrementally and testing for the freeze/bomb dialog.
But, today we have Firewire and none of those ancient issues (no free lifetime tech support either). My iMac's ports are all full, and I only know which devices are connected when I have to remove something for another device. iSight, scanner, card reader, external hard drive, USB soundsticks, etc. You wouldn't happen to have any SCSI devices hooked up, would you?
Out of curiosity, have you tried a different USB/Firewire port for the hard drive? Or run the hardware test DVD that comes with your computer? This weird freezing seems to suggest a problem with the computer, RAM or network more than a device. Bad devices, in my experience, cause kernel panics, not freezing.

I need help choosing a new MBP (previous one was stolen)

Hello everyone, I need help choosing my next macbook pro because my previous one (15" Core i7 high res anitglare screen) was stolen . As you probably tell I spent a lot of money on my previous one and now I am a broke college student that doesn't have $2,400 to drop on a replacement.
So this is where you come in... because of budget reasons I have been looking at the 13 inch macbook pro but I just cannot bring myself to spend $1200 on a laptop with old technology (Core 2 duo processor) not to mention it is only 2.4ghz. I am not really sure what to ask about it I think i just need some good stats or other convincing information to allow me to buy it.
I know about the student discount and the refurb. macs, are there any other reliable ways to get a less expensive MBP?
I am a converted PC user and I LOVE macs, please don't let my budget make me revert back to a PC...

Like you’ve already said refurb is a good option.
I know it’s a bit late now but let me point you in the direction of Prey Project.
Prey Project is an open source program I use on my MacBook Pro, it’s a program that can track your computer and phones if stolen using GPS / Google Maps etc to give you location of it.
It will also take pictures of who is in front of it, log what they are doing etc.
Check it out here http://preyproject.com/ this such an amazing program that is free to use, will work on Apple, Windows, Linux and Android phones.

Need help choosing processor and display for X240 please

I'm about to purchase an X240 today or tomorrow and, after doing multiple forum searches and reading a 67-page X240 thread elsewhere, I would really appreciate some help choosing a processor and a display. If it makes a difference, I've decided on:
*Windows 7 Pro 64 bit
*8GB of RAM
*256GB SSD
I intend to use the laptop for viewing/editing Word documents and Powerpoint presentations, streaming movies, and streaming recorded lectures. I'm not sure what lecture viewer/player my school uses yet, but I do know that it has options to play the lectures at accelerated speeds (1.5x, 2x, etc.) and that I will definitely need to use this feature. I'm not computer literate enough to discern whether the processor type has any effect on this. I will use an external drive if I need to download and save any lectures. I also plan to do some infrequent and basic photo editing with Windows Photo Gallery and MS Paint. I'm willing to pay extra for a smoother/faster experience, but I don't want to go with the i7 processor if it's overkill for my purposes or if there are other significant trade-offs besides price.
As for display, I'm torn between the regular HD (1366x768) IPS Non-touch, regular HD IPS Touch, and FHD IPS Touch. Re: HD vs FHD, I've been using a 1280x800 13.3" non-IPS display for the last 6 or 7 years, and I'm pretty happy with it except for the limited viewing angles. Wouldn't regular HD on a 12.5" screen be a step up in resolution? A lot of the reviews of the regular HD on the X240 express disappointment with the "low" resolution, but I don't know if it's really that bad, or if people just have much higher expectations/standards than I do. I'm leaning towards regular HD because my glasses are so strong that increasing the sharpness of what I see also has the side effect of making things appear smaller (minimization error), so I'd probably have to mess with text/DPI scaling if I went with FHD, which isn't a perfect solution from what I've read. I'd only consider getting a touch version if I need FHD (since it doesn't come in non-touch), or if it somehow makes the HD display sharper or more vibrant--I have no intention of actually using touch features.
Apologies for the length, and thanks in advance for any advice! :-)

Actually I have been doing further research and I personally would either go with the 2.6GHz NON RETINA MBP or cough up the cash and go all out on a 2.6GHz RETINA MBP and upgrade the RAM to 16GB and upgrade to 768GB Flash storage, I am a student as well so will get a discount which will help.
My fears are that if I get the Retina model I will not be able to upgrade it even further, I want to keep the computer for at least a good 5 years, during those 5 to 8 years will the current upgrades be enough to keep up with the top games and programs etc? Also I have read that repairing the Retina display model is very diffcult and it can malfunction commonly, so I am guessing I should get apple care on top of it just to be sure with this particular model?
I am assuming that they they will bring out the new models out next year and all the chinks and bugs of the current Retina model will be fixed so to speak, of which I have read there is a few... Would it be worth buying the NON RETINA MBP and then selling and upgrading to an improved RETINA MBP model next year?
Finally if i back up my files on a hardrive would I have to use the USP SUPER DRIVE to install files onto the RETINA MBP or can i directly do this without the USP SUPERDRIVE?
Thanks

Need help choosing optimal hardware for a laptop that will run AE CS5

BACKGROUND INFO (Questions listed below)
I need some help figuring out the best hardware configuration for a new laptop. I’m a student at a design school and I will be using the laptop to mainly run After Effects and to a lesser extent Photoshop and Illustrator. I don’t need to worry about 3D rendering software or Premier Pro. I am primarily interested in getting the best performance during editing. I am not looking for the best performance for final output. I would prefer to sacrifice final output times for better editing/interface performance.
I will be working with standard definition content and perhaps HD up to 720p on occasion. I do not need to operate in resolutions higher than 720p. My projects are generally animation and use many sources and many layers.
I’ve been reading up on optimal hardware configurations for CS5 but my understanding is still a little foggy and I would like to use this thread to figure out how to build the best machine for my budget. The budget is about $1400 to $1600 CANADIAN after tax.
I DON’T need help finding the laptop. I will search for it on my own. I just need to understand the best hardware to purchase within my budget.
I realize that it is probably impossible to buy the laptop I want with the hardware configuration I need “off the shelf”. Instead I will be looking for a good base model (~$900-$1100) and I will purchase the necessary hardware upgrades separately. I will not be purchasing a Mac.
Right now I’m thinking of a machine built something like this:
- 15”-16” screen (17” models are too big/heavy)
- Mid to high end i5 processor OR entry level i7 quad core
- 8GB RAM (I would go to 12GB, but it’s hard to find a 15”-16” laptop with 3 memory slots)
- SSD to replace HDD (However, if possible, I would like a laptop with dual HDD support or swap the optical drive for another HDD. If I had access to 2 drives, I would have and HDD/SSD combo).
- Medium/high end NVIDIA GPU to take advantage of OpenGL while editing.
QUESTIONS
1) Does the “Render Multiple Frames Simultaneously” option enhance general editing performance (applying filters, scrubbing through the timeline, reverting history states)? Or does it ONLY help speed up RAM previews and final output? Does it reduce the length of RAM previews?
1b) Is this option even necessary to enable on 64bit systems? (As far as I understand it was used to solve a problem where 32bit systems/software would only recognize 4GB of RAM per instance of AE).
1c) If I turn this option on to help with RAM previews, would I be hindering general editing performance in any way? Or does this option have basically zero drawbacks?
2) How come “Actual CPUs that will be used” will read 0 even if the sum total of RAM assigned to the CPUs plus the RAM reserved for other applications is less than the total available system RAM (on a 64bit system)? For example, I currently have 4GB RAM and 2 installed CPUs. I have 1.5GB reserved for other programs and when I set 0.75GB per CPU both CPUs are used. However when I set 1GB per CPU then 0 CPUs are used, even though the total RAM adds up to only 3.5GB.
CPU
3.) Considering the fact that I am more concerned with smooth performance while editing rather than final output speeds, would it be better to get a dual core i5 clocked around 2.5 or a quad core i7 clocked around 1.8?
4.) What is the difference between an i3 and an i5 processor even if they are clocked at the same speed? How does an i5 460M compare on the grand scheme of things?
RAM
6.) Should the quantity of RAM that I get (8GB vs 12GB) be based on the number of cores in my CPU? If so, how should I be calculating optimal RAM based on # of cores. Should I also be counting threads, or just actual physical cores?
STORAGE/SWAP
7.) Should I replace the HDD with an SSD? I'm looking for snappy interface performance while editing. I would think that if the RAM fills up it would be best to have the SSD for scratch/cache.
8.) What performance benchmarks are most important when considering an SSD for After Effects? (4k writes? IOs per second? Max read/write?)
9.) I can afford the OCZ Vertex2 120GB SSD. Would this be a good choice if an SSD is recommended?
10.) Would it be better to have 8GB of RAM and an SSD, or 12GB of RAM and an HDD? Explain why.
GPU
10.) After Effects utilizes OpenGL to enhance editing performance. I will not really be using Premier Pro, so catering to the CUDA Mercury Engine is not a concern. Do high end gaming cards provide significant gains in OpenGL performance? Or do OpenGL performance gains taper off around the mid-range GPUs? (i.e. can you justify buying a high end GTX 260M graphics card for enhanced editing performance versus an "entry level" dedicated card like the 310M?)
11.) What hardware specs are most important when considering a GPU for editing performance in AE? (Memory size? # of Pixel shaders? Core speed? Shader speed?)
Thanks so much for any answers you can offer to these questions.

Please make sure that you've read through this page and what it points to.
> 1) Does the “Render Multiple Frames Simultaneously” option
enhance general editing performance (applying filters, scrubbing through
the timeline, reverting history states)? Or does it ONLY help speed up
RAM previews and final output? Does it reduce the length of RAM
previews?
It only increases rendering speed for RAM previews and rendering for final output. In After Effects CS5, it doesn't decrease the length of RAM previews. (In CS4, it does.)
1b) Is this option even necessary to enable on 64bit
systems? (As far as I understand it was used to solve a problem where
32bit systems/software would only recognize 4GB of RAM per instance of
AE).
You misunderstood. Yes, it's still relevant on 64-bit computers. Moreso, in a way. (I'd rather not spend my entire Sunday writing out detailed answers to satisfy idle curiosity, so I'm not going to give all the technical detail to that answer.)
> 1c) If I turn this option on to help with RAM previews,
would I be hindering general editing performance in any way? Or does
this option have basically zero drawbacks?
It takes a small but nonzero time for the background processes to start up when they need to be used and shut down when they're done. And as they sit waiting, they take up a little bit of memory. So, it's not exactly correct to say that there are no downsides to leaving it on. But it's close. I leave it on.
> 2) How come “Actual CPUs that will be used” will read 0 even
if the sum total of RAM assigned to the CPUs plus the RAM reserved for
other applications is less than the total available system RAM (on a
64bit system)? For example, I currently have 4GB RAM and 2 installed
CPUs. I have 1.5GB reserved for other programs and when I set 0.75GB per
CPU both CPUs are used. However when I set 1GB per CPU then 0 CPUs are
used, even though the total RAM adds up to only 3.5GB.
4GB - 1.5GB for other software leaves 2.5 GB for After Effects.
If you have 1GB assigned per background CPU, then the foreground takes 1.2x that = 1.2GB. That leaves 1.3GB for background processes, which is enough for one background process. There's no point in starting only one background process to do rendering, so it doesn't bother. (Note: When background processes are rendering, the foreground process isn't rendering.)
> 3.) Considering the fact that I am more concerned with
smooth performance while editing rather than final output speeds, would
it be better to get a dual core i5 clocked around 2.5 or a quad core i7
clocked around 1.8?
Get the quad-core. That gives you a greater total number of cycles. And After Effects works very well with mutliple processors, even beyond Render Multiple Frames Simultaneously multiprocessing. An entirely unrelated sort of multiprocessing (multithreading) spreads work out to multiple processors.
> 6.) Should the quantity of RAM that I get (8GB vs 12GB) be based on the number of cores in my CPU? If
so, how should I be calculating optimal RAM based on # of cores. Should
I also be counting threads, or just actual physical cores?
The optimum amount is the amount that you can cram into the computer. I'm not kidding. Spend your budget on RAM until you have 4GB installed per processor (and I'm counting the virtual processors due to hyperthreading). If you have a quad-core, that's 8 CPUs with hyperthreading, so the optimum amount of RAM installed is 32GB. You can work with less, but you did ask about optimum. For HD work (i.e., 1920 pixels across), you're OK with more like 3GB installed per CPU. That's what I have at home: 24GB in a quad-core. You're going to assign 2/3 or so of the RAM to After Effects, so 3GB installed per CPU is 2GB per core for HD work in After Effects.
> 10.) Would it be better to have 8GB of RAM and an SSD, or 12GB of RAM and an HDD? Explain why.
12GB of RAM. Because After Effects likes RAM. (If you're thinking of deliberatly using virtual memory to swap memory to the hard disk, don't. That's a performance killer.)
> 10.) After Effects utilizes OpenGL to enhance editing performance.
Not really. If you're on a limited budget, don't even think about the GPU until you've already got the most RAM, the fastest CPUs, the largest number of CPUs, two fast hard disks, and a couple of good monitors. Then, and only then, should you even consider getting soemthing beyond a non-stock graphics card. Yes, OpenGL can be used to accelerate some things, but that's only for the low-fidelity preview renderer. (Pardon the bluntness, but I want to make sure that you heed this.)

I need help choosing a scanning software

I am a real estate appraiser, and I generate fairly large 8.5x11" paper files for each report I create - maybe 20-30 pages. Is there any software that will scan my stack of paper, allow me to add a "section title page" in the appropriate place (for example, "order", or "contract", or "survey") to each stack, and then create a "tab" for that title page? Right now I just have a stack of paper, all in the proper order, in a manila folder that goes into a file cabinet. Typically it consists of the order from my client, then tax records, then contracts, surveys, statistical data I produce, comparable sales data, and "other" items.
What I am trying to accomplish is to build a PDF "book", so that when I look at that PDF document, I see these tabs that I use every day and I can go right to that section to see the info within. I guess it would be the same as a bookmark; I want the software to use OCR to scan the entire folder of papers, but while doing so it would see that page that only has "Survey" written on it and automatically know to make that a bookmark. I don't really have time to scan each group of papers, create bookmarks, create a table of contents, etc; I just want to be able to drop my bundle of papers into my scanner, hit "scan", and then save that PDF document to the proper place on my PC.
Am I asking for way too much?

This one would probably be best for you.

HOW DO YOU GUYS DEAL WITH APPLE.. SO CONFUSING...NEED HELP WITH SPECS FOR PURCHASE OF IMAC 21.5

Hi guys, been reading your forums, blogposts, etc and am getting more confused. I'm just a video girl trying to produce meaningful content through web videos for small to mid sized businesses and want to come over from the dark side.
Good news,, I dont need a super giant system, I do simple editing for web videos, minimal graphics, no motion graphics, no animation etc. currently using CS4, will probably end up with 5.5.
I want to get imac 21.5 or 27 if i have to.. So here's the question we all have,,, what do I really need besides an Apple fairy godmother to figure this crazy stuff out?????
I want to be able to have firewire add on, but the rest is what I need help with. So i've been looking at cs6 specs, even though im not there yet, eventually will be,, so just need to run cs4 now and build from there. I also want to eventually move to final cut down the road so I want imac able to upgrade to final cut.
WHAT DO I REALLY NEED MINIMALLY FOR NOW? WHAT CAN I GET LATER IF i CHOOSE TO DO MORE AND NEED MORE POWER?
cs6:
Multicore Intel processor with 64-bit support
Mac OS X v10.6.8, v10.7, or v10.8**
4GB of RAM (8GB recommended)
4GB of available hard-disk space for installation; additional free space required during installation (cannot install on a volume that uses a case-sensitive file system or on removable flash storage devices)
Additional disk space required for preview files and other working files (10GB recommended)
1280x900 display
7200 RPM hard drive (multiple fast disk drives, preferably RAID 0 configured, recommended)
OpenGL 2.0–capable system
DVD-ROM drive compatible with dual-layer DVDs (SuperDrive for burning DVDs; Blu-ray burner for creating Blu-ray Disc media)
QuickTime 7.6.6 software required for QuickTime features
Optional: Adobe-certified GPU card for GPU-accelerated performance
Any responses would be great. I know you guys are busy answering the really high end tech questions

All the current iMac models (both 21.5" and 27" with OS X Mt. Lion 10.8) will run CS4, 5.5 and 6 just fine. They will also run Final Cut Pro X just fine. Ditto for most any application you may want to use.
Below are some notes (specific to your apparent requirements) that may help you with your purchase decision:
Notes on purchasing a 21.5" iMac
All 21.5" iMacs come with 8GB RAM but you cannot add more later. I strongly suggest getting the maximum RAM (16GB) when you order the iMac.
The basic hard drive is a 1TB 5400rpm drive. It will work fine with Adobe CS but you will probably want the added speed of the optional 1TB Fusion drive for better performance. Some people will recommend/argue for one of the optional SSD drives instead, but they are very expensive and still only come in relatively small capacities - I don't recommend the SSD drives. Get the Fusion drive and spend any extra money on a good external hard drive for backup and/or extra storage instead of an SSD.
Notes on purchasing a 27" iMac
All 27" iMacs come with 8GB RAM and you can add more later, up to 32GB
The basic hard drive is a 1TB 7200rpm drive - it will be fine with Adobe CS. There are upgrade options to a 3TB 7200rpm drive or a 1TB or 3TB fusion drive - these will be fine also. There are also SSD drive options, but I do not recommend them. (Same comments as above.)
Notes on all the current iMacs
iMacs no longer come with built-in CD/DVD drives. If you need one, you will need to purchase the Apple Superdrive accessory drive ($79)
All of the iMac graphic processors (GPU's) are compatible with Adobe CS 4, 5.5, 6
It is very difficult to impossible to change or upgrade the hard drive later on, so don't buy low-end thinking you can add a better internal hard drive later.
Be aware that Macs always come with the latest (most recent) version of OS X. And OS X Mavericks (10.9) is due to be released soon (in the next month or two). There is no guarantee that the older Adobe CS 4 or 5.5 versions will run on OS X Mavericks. If you cannot upgrade to CS 6 in the near future, you may want to purchase now rather than after OS X Mavericks is released.
For what it's worth, I'd recommend the 27" iMac if your budget can afford it. You will appreciate the larger screen size and added capabilities over the years you will use the computer.

Help choosing hardware for lab mirco distilling fermenting plant

Hi,
I have been fiddling around with LABview for a while now but i have a hard time choosing hardware for a simple slow lab scale fermenting and distilling plant. The hardware should be pc based and able to gather data from various sensors and manipulate pumps and valves. i have been looking into the USB-6501 USB Digital I/O but i am not sure if that is what i need. Any input would be appreciated.

No one can help you without more information.
What kinds of signals do the sensors generate? What kinds of signals do you need to control the pumps and vlaves? How fast do things need to be measured and controlled? How much reliability do you need? (That means: Does some thing bad or expensive happen if the computer, software, or DAQ equipment shut down or fail?)

Need help writing script for Digital DAQ

Hello,
I am trying to write an aquisition program for digital input coming from a hall sensor. I will be passing a magnet over a hall sensor on a motor and want to record the number of rotations. I have pasted together a script based on various websites, but it isn't functioning the way I want. I would like to be able to collect data points indefinately, or fixed, and then print out the resulting count. I have attepted to use the ctypes wrapper in Python. The NI functions remain unchanged though, so if you don't know Python it shouldn't be a problem to read. I am using a NI PCI-6503.
NI PCI-6503
NI PCI-6503
NI PCI-6503
The code:
# C:\Program Files\National Instruments\NI-DAQ\Examples\DAQmx ANSI C\Analog In\Measure Voltage\Acq-Int Clk\Acq-IntClk.c
import ctypes
import numpy
nidaq = ctypes.windll.nicaiu # load the DLL
# Setup some typedefs and constants
# to correspond with values in
# C:\Program Files\National Instruments\NI-DAQ\DAQmx ANSI C Dev\include\NIDAQmx.h
# the typedefs
int32 = ctypes.c_long
uInt32 = ctypes.c_ulong
uInt64 = ctypes.c_ulonglong
float64 = ctypes.c_double
TaskHandle = uInt32
# the constants
DAQmx_Val_ChanForAllLines = int32(0)
def CHK(err):
"""a simple error checking routine"""
if err < 0:
buf_size = 200
buf = ctypes.create_string_buffer('\000' * buf_size)
nidaq.DAQmxGetErrorString(err,ctypes.byref(buf),buf_size)
raise RuntimeError('nidaq call failed with error %d: %s'%(err,repr(buf.value)))
# initialize variables
taskHandle = TaskHandle(0)
max_num_samples = 1000
# array to gather points
data = numpy.zeros((max_num_samples,),dtype=numpy.float64)
# now, on with the program
CHK(nidaq.DAQmxCreateTask("",ctypes.byref(taskHandle)))
CHK(nidaq.DAQmxCreateDIChan(taskHandle,'Dev1/port1/line1',"", DAQmx_Val_ChanForAllLines))
CHK(nidaq.DAQmxStartTask(taskHandle))
read = int32()
CHK(nidaq.DAQmxReadDigitalU32(taskHandle,int32(-1),float64(1),DAQmx_Val_GroupByChannel,data.ctypes.data,max_num_samples,ctypes.byref(read),None))
print "Acquired %d points"%(read.value)
if taskHandle.value != 0:
nidaq.DAQmxStopTask(taskHandle)
nidaq.DAQmxClearTask(taskHandle)
print "End of program, press Enter key to quit"
raw_input()
This script returns "Acquired 1 points" immediately, regardless of how many times the hall sensor has been switched.
I apologize for the sloppy code, but I understand very little of the underlying principles of these DAQ functions, despite reading their documentation. Seeing as how the code does not return an error, I am hoping there is just a minor tweak or two that will be farily obvious to someone with more experience.
Thanks

Hey Daniel,
Most of this script is from http://www.scipy.org/Cookbook/Data_Acquisition_with_NIDAQmx.
I needed to run the ReadDigitalU32 function in Python loop because my DAQ device did not support timed aquistion and I don't have LabView.
import numpy
import time
import ctypes
nidaq = ctypes.windll.nicaiu # load the DLL
# Setup some typedefs and constants
# to correspond with values in
# C:\Program Files\National Instruments\NI-DAQ\DAQmx ANSI C Dev\include\NIDAQmx.h
# the typedefs
int32 = ctypes.c_long
uInt32 = ctypes.c_ulong
uInt64 = ctypes.c_ulonglong
float64 = ctypes.c_double
TaskHandle = uInt32
# the constants
DAQmx_Val_Cfg_Default = int32(-1)
DAQmx_Val_Volts = 10348
DAQmx_Val_Rising = 10280
DAQmx_Val_FiniteSamps = 10178
DAQmx_Val_GroupByChannel = 0
DAQmx_Val_ChanForAllLines = int32(0)
# initialize variables
taskHandle = TaskHandle(0)
max_num_samples = 10000
data = numpy.zeros((max_num_samples,),dtype=numpy.float64)
read = uInt32()
bufferSize = uInt32(10000)
def CHK(err):
"""a simple error checking routine"""
if err < 0:
buf_size = 200
buf = ctypes.create_string_buffer('\000' * buf_size)
nidaq.DAQmxGetErrorString(err,ctypes.byref(buf),buf_size)
raise RuntimeError('nidaq call failed with error %d: %s'%(err,repr(buf.value)))
# Start up DAQ
CHK(nidaq.DAQmxCreateTask("",ctypes.byref(taskHandle)))
CHK(nidaq.DAQmxCreateDIChan(taskHandle,"Dev?/port?/line?","", DAQmx_Val_ChanForAllLines))
CHK(nidaq.DAQmxStartTask(taskHandle))
#initialize lists and time 1
t1 = time.time()
times = []
points = []
while True:
try:
CHK(nidaq.DAQmxReadDigitalU32(taskHandle,int32(-1),float64(1),
DAQmx_Val_GroupByChannel,data.ctypes.data,uInt32(2*bufferSize.value)
,ctypes.byref(read), None))
t2 = time.time()
#data[0] is the position in the numpy array 'data' that holds the value aquired
#from your device
points.append(data[0])
times.append(t2 - t1)
t1 = time.time()
#Choose time interval between data aquisition
time.sleep(.02)
except KeyboardInterrupt:
break
#process the lists of points and time intervals as you so choose
Thanks for the help!

Preloader for a slide presentation

I have created an online comic using the slide presentation
method so that people can move forward and backward through the
comic...however I am needing to upload this with a preloader at the
beginning so people can see the progress of the download. I am
quite new to flash and could really use a clear straight forward
method of doing this if anyone knows how. Any help is greatly
appreciated!!!

Funny, but I came to ask the exact same question. I put my
regular preloader into the main application timeline, but it
doesn't seem to work. Any expert help appreciated.
BTW, I am using the Form application method.
