Why do you want them saved in LV 7.1? Are you trying to help answer the question?
They are saved in LV8.2.1 which means the original poster would have to save them back by 2 versions (they would need LV8.0 to do that). Considering they are obviously a newer user to the forums (first logging in in Dec 2009), they probably are not a long time LV user who would have version 8.0
If you only have version 7.1, you aren't going to be able to help very many people on the forums.
By the way, please type your replies using full English words "u"="you". This is a professional forum and not a bunch of teenagers text messaging each other on cell phones.

IMAQ image out- what's the best way?

Hello forum,
I'm developing an interface to acquire a square image from an NI-DAQmx PCI 6221 on LabVIEW 7.0 and Windows XP. At present I am simply collecting my information from a physical sine wave generator on the bench, but eventually this will be used to process images from a CARS microscope.
My problem is that I am trying to figure out a user-friendly way of "buffering" all previously acquired images in the session, and then choosing one several of them to save as an uncompressed BMP. At the moment I am using two image displays; one for the whole image overview (picture indicator) and one to pan around and zoom on fine details (IMAQ image indicator). The IMAQ image indicator is also outputting to an IMAQ browser window, which I have modified based on the Browser Example.vi which ships with LV. However, there are several difficulties with this method.
Firstly, I'm not sure how to select an indexed image from the browser itself to save; the only way I can think of would end up wiring the IMAQ image out to the BMP writing VI, but that would only save the current image, and not necessarily the one the user wants.
Secondly, I haven't quite got the hang of combining case structures, event structures and while loops yet, so there's a very specific order things have to be done in or the program hangs, (e.g.. you must press the buttons: Acquisition - Unlock Browser - Stop in that order, nothing else works properly), and I'm pretty sure I've set the browser up wrong because every time I finish with the acquisition window, an error message appears.
Thirdly, it would be nice if I could hide the browser window until I've finished with the other window, but I can't seem to get IMAQ windshow to do that. I have boolean constants wired to Hide/Show and Set/Get but no matter what combination of false and true I use, the window appears anyway.
I will attach the VI and subVIs to this post in a zipped folder, and would appreciate any help you could give me. General constructive criticism on my wiring, methods, Rude Goldbergs, etc, would also be appreciated if anyone has the time, as I'm still pretty new to LabVIEW.
Thanks in advance!

Image Acquisition VI 0.4.zip ‏187 KB

DH is right about the difficulty in removing wind noise, but hoping it might prove useful, here is a hint I copied from a thread somewhere in this discussion list.
How to export audio from Final Cut Express to (free) Audacity and back again after noise removal.
1) download Audacity
2) in fce timeline, place in and out points at beginning and end of audio
3) select that audio clip, and that clip only
4)file-export-using quicktime conversion, in the pop-up box format as aiff, 44.1kwh 16bit stereo
5)open audacity, make sure box in bottom left corner says 44100
6)file-import-audio
7)go to file and select it, click choose
8) select part of audio with just wind noise, then go to effects noise removal, click get noise profile etc.
9)when satisfied, click file-export, click ok, close audacity
10)Open fce, drag your audio clip to the right hand end of clip. Move playhead to the in marking. Go to File-import
select your audio file, choose.
11) file appears in fce browser. Drag from there to overwrite and the audio goes into the track, perfectly synced
My apologies to whoever posted this hint, I tried to find the name to give credit. This really does work to get rid of room hum, but wind noise is a really different beast and this may not help. I suspect, as DH says, it will remove too much of the audio you want to keep. Hugh

How I FIXED the black out problem!

I posted this in another thread, but thought it might get lost, so I'm posting it here in the hopes that it may help others who are out of warranty and have nothing to lose.
Please know that this is a very diffcult procedure and if you're not comfortable with the idea of possibly destroying your entire laptop, don't even think about trying this!
First, you will need to download the appropriate service manual for your model PowerBook:
http://home.earthlink.net/~strahm_s/manuals.html#pbks
Second, I would highly recommend that you go to your local Radio Shack and pourchase the correct tools. You will need a set of precision screwdrivers and a Torx #8 (I think) also. I also recommend that you obtain about 15 of those little zip lock baggies that they put extra coat buttons into (of course any bag will do).
As you take apart the laptop and remove the screws, you should place each screw set into a bag and label it with a Sharpie. Believe me, this is worth the time and effort to do this. The service manual will list an Apple part number for the screws as you take them out. When you reassemble the laptop, you will simply find the part number of the screw you need.
The Problem (Overview):
My screen would flicker between all black parts in the lower 1/3 to 2/3rds of the display. Adjusting the angle of the display would generally fix the issue until it was moved again or needed another adjustment. I used it like this for a few months before it finally was no longer fixable by simply adjusting the display. One day it just wasn't fixable by adjustment anymore. I couldn't see anything above 2/3rds of the display. previously, the powerbook had been dropped on the corner by the power plug, and must have caused damage to the display.
At first I thought it was a loose connection in the LVDS or video cable, but upon taking the entire unit apart, I found that the cable was very secure and no amount of jiggling it had any effect on the display itself. It definitely wasn't a pinched cable or loose connection in the cable.
I then started a search to buy a replacement screen. And upon taking the unit apart to remove the panel itself from the rear casing, I would preiodically plug the power back in and power up the PowerBook to see if anything I was doing was having any effect on the display. With the rear casing removed, I noticed that applying slight pressure on the rear of the screen on the left middle edge would affect the display and cause the image to appear again perfectly.
Obviously, I couldn't use the PowerBook this way, so I cut some narrow strips of rubber and used a glue stick to adhere them in the same spots where my fingers were. With the rear casing snapped back in place, it applied direct pressure to this same area, resulting in a perfect picture!
The actualy rubber pieces I used came from underneath the Airport card, so if you want to use something else, perhaps a strip from a bicycle innertube would do the same trick and would be of the same thickness.
Since putting it back together, the image is perfect. I have noticed that some [hard] direct thumping of the display bezel or hard shaking of the unit will cause some flicker, but in the past, even the slightest motion would knock the image out. So IMO, this is an incredible improvement. Since my "repair" I haven't had the issue appear once!
If you have no other solutions to try, and are somewhat savvy with taking things apart, give my method a shot. I'm just amazed that it works so well!
The image is of the rear of the panel. Facing you, it would be the left side of the screen. Where you apply the strip may be in another location. I don't recommend putting it anywhere except on the edges of the screen or you will likely damage the panel or introduce spots or pressure smudges. Good luck!
BTW, you may be able to test to see if your panel could be fixed with a similar approach by gently squeezing the sides of the display while it's connected to your laptop and watching for the screen to come back or flicker more. In my case, the squeezing definitely affected the image quality: when I applied pressure the image was stable. When I let go, it went to $hit.

I just switched to Roadrunner and am having the same "can't send email" problem. I have done what you suggested, but the problem persists. I did note that in my outgoing mail server box it says: smtp-server.wi.rr.com:jzelinger3 (Offline). I'm not sure where the "Offline" is coming from or why it is there. Any suggestions? I performed the following Terminal tests with a tech. support person from Roadrunner:

TV OUT Problem this is how I solved.

Well, first of all I cannot guarantee if this will work for all people with tv out problems. TV with PC I think will always be a BIG headache .
How I did fix my TV OUT problem. Since I live here in Brazil, people have a problem with the system that is Pal-m. But this is easy to set up, since you just have the screen working on your TV.
The first thing that I did is to remove completely the most recent NVDIA drive (not the one made for MSI) that is 30.82. I also removed the WDM driver. Since Im using XP I didnt have to reboot 30 times just 20, , yes 20 reboot times to see if everything was all right, it took me about 1,5 hour of work.
The second thing was that I started to install the driver that came with my MSI Card (Geforce4 MX-460 TV OUT). The version was 27.50. The TV out problem was gone. I got a really nice image from the screen.
Than It came the must boring part. ;( I tested all nvidia drives from 27.50 to 30.82. Look the results I got concerning just the nview situation(dual monitors):
Nvidia 28.32. work with nview.
nvidia win-xp-2k-2835 work with nview.
nvidia win-xp-2k-2880 doesnt work with nview.
nvidia win-xp-2k-2890 doesnt work with nview.
nvidia win-xp-2k-2911 doesnt work with nview. Not all parts from the driver was updated, someone belongs to 28.90.
nvidia win-xp-2k-2920 doesnt work with nview.
nvidia win-xp-2k-2942 doesnt work with nview.
nvidia win-xp-2k-2960 doesnt work with nview.
nvidia win-xp-2k-2980 doesnt work with nview.
nvidia Win2k-xp-29.90 doesnt work with nview.
nvidia W2K_XP_V29.90 doesnt work with nview
nvidia Win2k-xp-3020 doesnt work with nview
nvidia Win2k-xp-3030 doesnt work with nview.
nvidia Win2k-xp-3082 doesnt work with nview.
I got all this drivers from a really nice site: 3dchipset .
Of course most of these are beta drivers and due to my limitation knowledge, I dont know why the nview display stopped to work at version 28.32.
And the last. The driver 28.90 driver did a really fatal crash on my PC when I was using my web camera and the nview together. It just shut down my PC, at once. X(
That all folks

Yes, that's how iMessage should work. Try this. Sign out of Messages on both devices. Sign back in on your phone and wait until it activates. Go to Settings>Messages>Send & Receive. Make sure Start New Conversations From is set to our mobile number. Then sign in on your iPad using the same Apple ID as you use on your phone. Once it activates, verify the settings. I've got iMessage syncing across my iPhone, iPad and MBA. Every once in a while, there's a glitch but rarely.
Best of luck.

Problem: codebase, jar and image reloading problem please help!

Hi Java Gurus,
I have written an applet that extends JApplet for viewing webcam. In order to reduce the download time I put my classes into a doorcam.jar file. The following is my <applet> tag in my html file.
<applet code="CameraApplet.class"
archive="doorcam.jar"
codebase = "webcam/classes"
width="375" height="475">
<param name="imagePath" value="http://judge/webcam/images">
<param name="webCamImage" value="door.jpg">
<param name="COMPort" value="COM2">
<param name="frameRate" value="10"> 
<param name="host" value="judge">
</applet>
The fist problem is that my class file does not get loaded from the jar file if i provide the "codebase" attribute as above. Instead the browser load every single class file from the webserver. This has some problem too. Coz the browser sometimes just thorough NullPointerException or ClassNotFoundException. After much of debugging I found out that the problem is the IE browser which seldom fails to load classes or image file from the server. If i referesh the browser the applet and all its classes loaded successfully and runs smoothly. This behaviour never occurs when running with "appletviewer".
I wanted all my classes to be loaded from my jar file. After much of trial and error I found out that if i remove "codebase" attribute the browser loads the classes from my jar file and applet loads very fast. This is where the second problem comes in. The browser does not reload my webcam image file so that the webcam become alive with live images, like before.
If I run on "appletviewer" everything works fine my web cam is displayed properly. But in IE browser the image does not get reloaded when I refresh my image to give live to my webcam display. The refresh method is given below.
private void refresh(final URL url) {
Image webCamImage =getImage(url);
webCamImage.flush(); // flush out the previous image
webCamImage = getImage(url); // get a new image
webCamImageIcon.setImage(webCamImage); webCamImageIcon.paintIcon(webCamLabel, webCamLabel.getGraphics(), 15, 15);
When I add the "codebase" attribute back, the image gets reloaded for every refresh() and everything works fine. But the classes are also loaded from the server. And occasionally also suffers Class loading and image loading problem. As I presented earlier, when I do refreshing in the browser everything gets loaded and the applet function correctly with web cam displaying very well.
The problem is so strange that I could not find any way to solve it.
It would be a great help to me if somebody provide me some work around to the problem.
I tested on Windows 2000, Windows XP, IE 5.5, IE 6 with J2SDK 1.4.0.
Thank you all very much in advance.
best regards,
Judge

Thank you so much for the suggestions. I did tried the way u suggested. The problem still the same.
I think its the problem between IE browser and Java Plug-in.
I which SUN would find these incompatibilities and solve these problems.
I even tried using java SDK and plug-in 1.4.1 it even worst. It can't even load an applet. And it does not show any loading messages nor any error messages. It just show a cross sign on the upper left coner.
I would be so glad, if Sun would try to eliminate the inconsistancies such as caching, loading, initializing etc between browser and its Java plug-In. For example, applets behave well in appletviewer and behave unpredictably in browser environment.
I have seen so many people in the forums with all sorts of problems because of this.
Right now I m desperately looking for work around to my problem.
If somebody would provide me with the solution to my problem it would be a great help to me.
thank you all so much.
best regards,
Judge

Taking a certain image out of a picture

I'm trying to take a particular image out of my picture to use as a logo and be able to put it on business materials. I'm not having any luck with it. Can someone tell me how to do this, PLEASE. Thanks!

ok
Open a blank file with same resolution as the object, go to Edit>paste. Save this as a JPEG. You can then insert this in WORD for your flyers, business cards, etc.
For the web site, you will need to save it with a transparent background. Go to File>save for web and save as PNG24.
If you have a problem, please post the picture and indicate what you want to extract, so that we may provide additional targeted guidance.

SSRS indicator image display problem!!

Hello ALL;
I am having problem with displaying indicator image in DEV report manager. but same rdl works in QA environment. Both server has SP1 installed. Any Idea? Appreciate for your help. Thanks,

Hi Techchi,
Based on the limited information, I cannot figure it out for this issue. As per my understanding, I think this issue can be caused by the browser that run the report manager. If you use IE explorer to render the report, I suggest that you can try to run
it in compatibility mode. If you are using another browser, I recommend that you should use IE explorer to render the report to check the issue again.
If this issue still exists, in order to solve the problem more efficiently, I need to clarify some information.
Are all reports with indicator image cannot render well in DEV report manager? Or just this one report?
What is the phenomenon about the indicator image display problem? Could you please post a screenshot about this?
It is benefit for us to do further analysis. Thank you for your understanding.
Thanks,

Having a image alignment problem using clearbox

Hi,
I'm having an image alignment problem. I cannot figure it out. I'm using the clearbox - lightbox dreamweaver widget. Using Dreamweaver CS6.
Actual page located here. Any help would be appreciated.
http://dirtysouthink.com/gallery/dustin2.html

This has very little to do with Dreamweaver. DW is merely a tool to assist you in building a web site. It is purely a matter of styling (CSS).
When I look at the structure, I see
BODY-CONTENT (width: 490px)
     GALLERY (width: 452px)
          CONTAINER (width: 500px)
               ITEM (width: 150px)
From this I can deduce that:
GALLERY will fit inside BODY-CONTENT
CONTAINER will NOT fit inside GALLERY or BODY-CONTENT
ITEM will fit three times into CONTAINER
To start with, I would reduce the size of the CONTAINER so that it fits inside of its parent. Then I would adjust the width of the ITEM so that only two of them fit inside of the CONTAINER.

How to solve the image display problem in the iTunes Store

Hi guys!
I just want to give a work-around for all of you having the image display problem in the iTunes Store. In my case only the square images in the slider sections won't load:
I had this in my last W7-installation and got it again in W8 after the first few weeks.
There are a lot of reports about this problem out there and adhoc solutions like 'clear the cache' or 'reinstall and drink ice tea' that do not work. It is obviously a file request error. It is all about finding out which server addresses get blocked by your computer.
Solution: Go to your firewall and your Anti-virus-program. There must be a whitelist option. In Kaspersky, check the web-options, the banner-options and the firewall-options, because the all have whitelists. The following addresses have to be whitelisted:
*.apple
*.mzstatic.apple.com.akadns.net
*.mzstatic.com.edgesuite.net
*.da1.akamai.net
*.itunes.apple.com
se.itunes.apple.com
upp.itunes.apple.com
ax.init.itunes.apple.com
xp.apple.com
*.mzstatic.com
client-api.itunes.apple.com
www.apple.com.edgekey.net
www.isg-apple.com.akadns.net
Press Ctrl + R in the iTunes Shop then and browse throught the music sections. All images should be displayed correctly now.
If not, there might be more Apple servers involved in your case. You can find them by running a DNS sniffing tool like the DNS query sniffer by Nirsoft or Wireshark.

Phone restarting randomly could be loose battery. Tighten by putting a small strip of electrical tape on the back edge.
THE BITTERNESS OF POOR QUALITY, LINGERS LONG AFTER THE CHEAPNESS OF PRICE, IS SOON FORGOTTEN.

Image reading problem in servlet

Image reading problem in servlet
I am reading an image in servlet and writing it to ServletOutputStream
The following code works fine unless I change the size of the byte array (for increasing download speed) from 8 to something like 128 or any other higher value
If I change the value of byte array size the image does not get downloaded properly, I mean the quality of the image changes, it does not looks like the original imageURL url = new URL("http://www.mysite.com/images/img1.jpg");
URLConnection con = url.openConnection();
con.setUseCaches(false);
BufferedInputStream in = new BufferedInputStream(con.getInputStream());
BufferedOutputStream out = new BufferedOutputStream(response.getOutputStream());
byte b[] = new byte[8];
while(in.read(b) != -1)
     out.write(b);
     out.flush();
out.close();
in.close();what do I change
byte array size
or use the constructor of BufferedInputStream with 2 parameter
or use the constructor of BufferedOutputStream with 2 parameter
or use flush outside while loop or what else

Change your while loop to:
int count;
while((count = in.read(b)) != -1)
     out.write(b, 0, count);
     out.flush();
}The penultimate time read is called, it may not fill the entire byte array. You only want to write out however much was read into the array.
For better performance, you should move the flush() outside of the loop too. BufferedOutputStream will flush automatically when its internal buffer is full.

Image aquisition problem

hi

oh god what is this
hi ?Q>
Solved!
Go to Solution.

Hi Mangood,
I've taken some screenshots of the step by step process for configuring the Vision Acquisition Express VI.
When you first place the Vision Acquisition Express VI on your block diagram, LabVIEW should pause for a moment and bring up a message saying "Initializing Vision Acquisition..."
After that, the configuration window for the express VI will open, and you will have the option to select your camera. In addition you can use the Snap and Grab buttons (circled at the top) to take a sample image from the selected camera. After you've selected your camera, you can then hit the next button.
On the next screen of the configuration window, you will have the option to select what kind of acquisition and processing you want to perform in your program. This will be dependent on your application, so read over the options and choose whichever works for you, then select Next.
On the next screen of the configuration window, you will have the options to change various attributes of the camera and the acquisition. These are all dependent on your camera and your application, so you can adjust these as needed. The defaults are often fine without any adjustment.
The final screen of the configuration window allows you to specify the inputs and outputs of the express VI. Depending on the options you've chosen you may have more options for inputs and outputs, but the most important one is the required output of "Image Out." This will be the indicator that allows you to see the image that you've acquired. Once you're happy with the inputs and outputs, you can click the Finish button.
Once you press the Finish button, LabVIEW will again pause and spend time configuring the Vision Acquisition Express VI with the settings you've specified. After it's done, you should be presented with a block diagram like the one below:
I hope this helps!

How show ONLY images with problems or needing metadata update, etc?

In LR3, how do I show JUST the images that are waiting for a metadata update on disk?
Or, more importantly, how do I show images that have a problem - the little box on the top right of the thumbnail with the exclamation point.
If I have a dozen images out of 50,000 that have an error with "another process has updated the metadata" I want to see JUST THOSE IMAGES
so I can fix the problem...
How do I do this?

Dave, there are two related issues:
- LR appears to have a number of problems correctly identifying which images have metadata conflicts between the catalog and the files proper:
http://feedback.photoshop.com/photoshop_family/topics/lr_3_5rc_reproducible_spurious_metad ata_file_needs_to_be_updated
- LR has no mechanism that allows you to identify just those images with metadata conflicts:
http://feedback.photoshop.com/photoshop_family/topics/metadata_collisions_between_catalogu e_and_files
Please visit these feedback topics and add your vote and opinion. Adobe pays closer attention to the feedback forum than this one.

Time out problem in BPS

BPS friends,
We have a planning function to copy Versions based with some filters. The copy function takes 5 hours and times out after that. The function is reaching max buffer size as recommended by SAP so we cant increase the buffer size anymore.
We are on BW-BPS 3.5.
How can I solve this time out problem? Please respond to me.

Hi Pat,
How many record did you copy ??
Could you restrict the copy in not 1 package ??
Package per package ...
I suggest you ..
e.g. you have restriction by a 0CALMONTH / something ..
Then,
You can copy e.g. for January to March, then March to August, etc.
You can automate it by planning sequence.
Hopefully it can help you a lot.
Regards,
Niel.
thanks for the points you choose to assign.

AirTunes with AirportExpress cut or drop out problems - my solution...

I buyed 2 of the Airport Extreme one month ago (Firmware 6.3, Itunes 7.1.1), never got them working fine, till yesterday...
I have A Zyxel ADSL WLAN Router Switch. WPA-PSK as I wanted a secure Network. Both of the AX were connected with static IPs. WLAN was always working fine, but I had many cut outs with airtunes. I wanted a solution with lossles streaming audio with the possibility to connect my Receiver digitally. That's why I bought my first Apple hardware, as I was always told, Apple=Plug'n play. Very frustrating!
I tried other switches, Routers, WLAN adapters and cards, nothing worked. Airfoil does not support multiple speakers yet, so it's useless for me.
In the FAQ of the Airtunes, Apple mentioned to use lower security, as some Computers probably do not have enough power to stream music flawlessly. But my Computers really do have enough power! I think the AX does not have enough power to do that. So I created another wireless network with one of my AX. I set the security to WEP-40bit key and joined this new Network with my other AX. Not the best solution, as I'm now connected to the Internet or to the AX to use Airtunes. Cables could fix that problem, but then I could use a wired system instead...
I use Channel 11 for the AX WLAN (the only clean channel in my area), Multicast to 11, only G mode for Wireless and a 5 characters WEP-40 key and no WDS. Seems to work at the moment.
I hope this will help others with the cut or drop out problem. If you have a working AirTunes system, please post your setup. Mostly I'm interested in a Setup with working WPA...

Thanks, I hope I can help others with this annoying problem...
Sorry, I forgot to write about the RF Interference. Belive me, I spent hours and hours searching for a solution in the Internet and every checkbox the Admin utility offered me to try out... I'm working as a system engineer, and supporting computer systems since the early 90ties, so I'd say I have a bit knowledge about all the networking, WLAN, Audio... In school we had the Apple Mac I with the 12" monochrome monitor and appletalk for networking quite funny!
But back to the RF interference: At the moment I activated it on both AX I own. I have a microwave, wireless phone and I'm living in a Area with many WLAN access points. I can choose between 6 networks!
I'm the only one with a network higher than channel 6, so this area is clean at least.
As my AirTunes do work at the moment, I'm not going to try if I could also deactivate it.
Next step is to try if I can connect the AX Router to the internet. A connection to my ADSL router should do that, but up to now I had very strange behavior when plugging in a ethernet cable to the AX. If this will work, it will be my final solution, at the moment I only see it as a workaround...
