Summer is good and especially treasurable in the "North Pole". Sometimes you really get so bored in a small town that barely has anything happening, especially for someone coming from a background of lot of people and noisy, (but that is called more "lively"), it can be very torture, people may not understand that. So we decided to revisit Niagara Fall, the first time this year. The thing makes Niagara Fall so attractive for me is it's nightless, lot of people (
), scary ride (I mostly liked to see other people getting scared, I wouldn't try anymore, had enough from Disney world, have you been to the terrorist tower? and the mission to mars? won't do it second time) and sometimes to try out my luck in Casino with my favorite blackjack. To my surprise this year, Niagara Fall is getting bigger, they expanded the Fall area and even built second Casino, is this a good way to make money when the economic is down? Anyway, I didn't go play, didn't want to line up, but people just can't wait to send in their money Walking along the street in the evening time was great, watching people passing by, sat at starbuck caffee on the street side, think nothing, but everything, and I've already forgotten how crucial the winter can be in this northern part of the earth.
Here is a photo taken at the street side of Niagara Fall.

Well, I don't know if you really want to do it as free (believe me, I don't say this just because I have the IVision, you are welcome doing it if you want, I don't live on IVision although it's very nice to get reward from it). As Rolf pointed out, it is a lot of work!. You not only need knowledge of C/C++, LabVIEW, but also image processing background, it's not like some people may think, straight translation of C to LabVIEW, if you don't know what's going on in each function, how do you test it and know the result make sense? (by the way, image processing was my favorite course in university and I got a very good mark a long time ago
so I do understand image processing, I always wanted to use it sometime and it sort of came to true with IVision). I'm not saying that you don't have these knowledge, just want you to know the scope. Although some people may feel that I do it on a hobby base, but it does take me many good days and late night doing it and full time dedication (I quited my job, it's harder than finding a job). Things that make me feel good is there are over 15,000 people looking at IVision and over 4000 or more download it. Many people use it for real work application and the feedback I got so far are good, some expressed very satisfied for what they doing. Although there are also many do not say neither good nor not good and I don't want to ask/know either. It feels a bit sad to know some people think it's just a hobby work, not seriously. Hmm... what's all my time spent for? Maybe my life is just wasted
. But I believe people who use it and know how to use it, they would know it's more than just hobby.Irene He ------ Author of IVision

Hi Allen,
The video settings will not be remembered in camera, so you need to set these video settings programmatically, if you don't like popup dialog and set manually everytime. IMAQ USB may not provide these features, but our IVision LabVIEW toolkit has this feature to set frame rate, resolution etc video settings programmatically.
Get a free full functional demo version of IVision LabVIEW toolkit here:

Thanks for the explaination, I didn't know that... But I can see you or whoever thinks the same way as you do, the condition of wirework symptom is pretty serious. You may need to get your head check out by the "Father of LabVIEW" or Dr. Truchard.

...when you start tieing both of your shoelaces at the same time.
...when you know exactly what x-y*floor(x/y) is.
...when you no longer wire the > and < signs backwards.
...when you think Jesus was born at noon on Friday, January 1, 1904.
...when you need to get a property, you aren't talking about Florida.
...when all of your description and tips are set.
...when you believe the answer is 28, not 42, because after that you are out of connectors.
....when you've begun to view your life as one big state machine.
...when your search engine defaults to ni.com rather than google.
...when you write by hand, words come out backwards.
Hahaha... just don't get the last one. It looks like David Letterman's top ten list.

That sounds a very good and interesting news. A year ago I was thinking of Wince.net (runtime OS only few dollars) for some consumer devices, but it still needs OS.
I wish I can invent something that every panda will own one (the 1.3 billionth panda was just arrived a few days ago)
------------again, this is just one of my day dream in the cafe pub.

Hi Jeff,
There is no direct way to register LabVIEW vi as callback function in C, but there is a way to work around by using the LabVIEW activeX server. Here are two links to info-labview that I answered before for your references.

The successful case is my IVision LabVIEW toolkit, it uses this technique to make LabVIEW vi as callback vi for real time video processing. If you want to get a feel how callback vi is working, you can download my Ivision at:

Hi,
I've made a LabVIEW vi that can be used to "hang" on any wire that you want to probe the data. You will hear the sound when data "streaming" through it. It uses the OpenG "Get Data Name__ogtk.vi" for getting the variant data input type, so you may need to download the OpenG LabVIEW Data toolkit. Here is the OpenG

It maybe a little bit late to answer this question, but I just noticed... anyway, my IVision LabVIEW toolkit can do just what you asked, capturing video from WDM supporting capturing devices such as USB camera, IEEE1394/firewire camera or DV camcorder. To get an evaluation version, you can download using the below link:

Yes, you are right, the white area would become transparent forever. That is because some bit set of the window need to reset back. I need to finish up the things on my hand before I can take a look into it. I'll keep you folks updated. Sorry for the meanwhile just restart your LabVIEW everytime. I know it's not very nice though, but...

some people asking for the source code of the DLL, I attach here now.

Well, I was thinking to use it to overlay my image window to other windows so that user can draw on the image window, but at the same time see the underneath window, for the purpose of some instruction or training software, an idea is if you can overlay on top of your graph and make some marks (circle, rectangle or line) like a professor. I thought other people may be interested in it too, so I donate here.

Recently I created a vi to make window semi/full transparent. I don't know if this function already exists somewhere, but anyway it's free. And I post here now.

Interesting, what media types are supported? I tried running mp3 files and it worked great, does it support anything else?
Michael Aivaliotis
Sorry, forgot the file format, the supported format are:
Windows Media™ Audio (WMA)*
Windows Media™ Video (WMV)*
Advanced Streaming Format (ASF)*
Motion Picture Experts Group (MPEG)
Audio-Video Interleaved (AVI)
QuickTime (version 2 and lower)
WAV
AIFF
AU
SND
MIDI

Hello everyone, attached is a multimedia vi that plays many format audio and video files. Just for your fun.
Niagara Fall is beautiful than ever
