• How use IMAQ extract Contour VI for the outline of an image of fine-art SEM?

  Hi, I tried to use the IMAQ extract Contour VI to get an outline of the cutting edge of a tool. After processing the SEM image into a binary, it is sent to the extracted IMAQ Contour VI, but it fails to find the outline and send the message "error 1074395732 occurred in the extracted IMAQ Contour-

  Possible reasons: IMAQ Vision: no curves were found in the image. ». I guess that the problem may be the parameters chosen for the extration of the curve of entry. The Vi and the image are attached below.

  Hi Ahryman,

  Please use the Forum of National Instruments.

  IMAQ extract Contour does not work with binary images, but with pictures of U8. You can look that up in the detailed VI help page.

  In your VI, just delete the line and that's all.

  I have attached the image result.

• Error 1074397153 has occurred to IMAQ get buffer

  Hello.

  I seem to have a problem with my camera Sony XC-EI50.  I use map of 1410 and trying to trigger outside to capture an image (using the FPGA, which is not really relevant here).  I have the adapter for camera DC-700, the trigger signal is connected to the BNC TRIG of entry.  The camera DIP switches are configured so that only 7th and 8th switches are turned on, while others are OFF.  Video output 1 is connected to the framegrabber, and the image is acquired via channel 1.

  Capture of the camera and snap features work perfectly in MAX, but I can't seem to use the Sony XC-EI50 CIM file, which could be the cause of the problem.  I get an error message when you try to load, so I use the RS-170 instead file.

  Is attached a simple .vi that I wrote it just to get the camera to work.  I run it and send a before trigger the 'get buffer vi' is to expire.  Then, I get a "error-1074397153 occurred at IMAQ Get Buffer.vi.

  
  

• IMAQ configure buffer - delay in the implementation of large number of buffers

  Hi all

  I don't know which forum I should post this in, but I hope that someone who can help me see this. I'm having a problem with a program that I wrote to acquire and store images from a camera to linear scan.

  My camera (SUI Goodrich, 1024 pixels) is connected to a card framegrabber (PCIe-1427), which is connected via a RTSI cable to a PCI-6731 card attached to a SCC-68 (series) connector M.  My goal is to drive a mirror galvanometer scanning and acquire images from the camera continuously on each scan. As the galvo scan will be the frame of an image (1024 pixels x 1024 lines).

  I managed to do it (I think), as my direct purchase program works exactly as I expected. However, when I try to save the images, I noticed that for a larger number of images, the starting point of the image is shifted the same amount for each image. I'm not really sure what's going on, it seems to me that there is a delay in the use of the VI "IMAQ set up buffer" when a large number of buffers is used.

  I would really appreciate any idea or ideas that anyone could have on this issue.

  Sincere greetings,

  Gill

  I fixed the problem by doing that I don't use actually 1000 stamps to save 1000 frames. Program works if the number of buffers is lowered.

• How to view analog channels during an ongoing acquisition, what type of used wave form, table, or chart?

  I use Labview 8.5. and the NI USB-6210 device.

  I want to display the analog channels over the continuous acquisition.

  I can use the table of waveform or waveform graph. Waveform allows you to eat a history buffer. This function is very interresting and useful for my system, but I can't change this value to programming (if I do not mistake!). So, I was wondering if I can also use the waveform graph, but I do not have how to make a circular buffer to replace function "history buffer. I have to use the waveform as a data type.

  What is the best solution for my problem? I would like to know if my solution is good (graphic use of waveform) and if anyone has a solution to make an effective circular buffer with the waveform data type?

  Thanks in advance, best regards, Daniel

  There is an example that comes with LabVIEW called "XY table". It shows you how to create a history for a XY Chart buffer. The size of the history can be changed on the fly. You can adapt the VI "graphic buffer XY ' to work with a data type of waveform." This type of data consists of 3 elements: start on time, delta t and table of values. The only thing that you should be buffering is the array of values.

• IMAQ under Win XPx64 with PCIe-1433

  I have an IMAQ application written with VS2008 (managed C++, using PInvoke). The 32-bit version works fine. But I want to build a 64-bit version.

  I have IMAQ 4.4.0 (March, exit 2010) installed. My framegrabber is a PCIe-1433. I am running Windows XP Pro x 64 on a machine of BOXX Technologies.

  When I build an x 64 version, I get the error 0xBFF60150 of imgSetBufferElement (...) IMG_BUFF_ADDRESS...). imgShowError tells me that this means "the operation is not supported for 64-bit applications."

  This error means I can't do a x 64 build with IMAQ under XPx64?

  Or does this mean that one of the parameters to imgSetBufferElement (...) IMG_BUFF_ADDRESS...) is incorrect?

  Thanks in advance.

  Hi jhc2,

  If you look at the signature for imgSetBufferElement, you will see that the value of parameter is defined as a uInt32. It is not compatible with a 64-bit being the pointer 64 bits wide application. If you take a look at the C examples included with your version of IMAQdx you can see how the replacement function imgSetBufferElement2 must therefore serve as a replacement in the new code (imgSetBufferElement should now be listed as "obsolete" in the header). The new version replaces the old version of the function and is compatible with 32-bit and 64-bit code. The syntax and parameters that are passed must be identical.

• during extraction of tasks / events for warehouses of data with powershell

  Hi, I'm looking for the extraction of tasks using powershell events (the same information you will find in using customer vi, inventory home, tabs for data warehouses, tasks, and events) to find the task of 'delete' (for example)

  I would like to use the Get-Vievent command, but I'm unable to use the - entity. Get-datastorename data store

  I think that using the data store object is not possible for the get-vievent command.

  So I use:

  
  

  Get-Vievent - MaxSamples 100000 | WHERE-object {$_.} FullFormattedmessage-match 'delete'} | Select Createduserid, username, FullFormattedmessage | Export-csv "c:\export_ds.csv" - noTypeInformation - UseCulture
  

  It works but it is very slow (my environment is very large)... and I've reached the limit - maxsamples.

  Is there another way? or I have to use - start - stop to limit the number of events, and to several reports by month?

  Thank you very much

  Thierry

  The current version is not it, but it's a good idea.

  I'll update the function.

• Extract pages to separate pdf files (something wrong with loop?)

  Please check following code.

  Acrobat makes copies of the original file with all pages in each new files generated instead of the extracted pages right (example: filename_page_2.pdf should be page 2 of the original pdf).

  Another issue is that now when the script is running, which is at the end of the batch that acrobat asks to save the original file

  What I am doing wrong?

  / * Extract Pages to the file * /.

  
  var re = /. * \/|\.pdf$/ig;

  
  var filename = this.path.replace(re,"");
  var lastPage = this.numPages - 1;

  {
  for (var i = 0;  I < this.numPages;. i++ )
  this.extractPages
  ({
  Start: 0,
  nEnd: lastPage.
  cPath: filename + "_page_" + (i + 1) + ".pdf".
  });
  };

  Start must be, not 0.

• Ongoing problems with mail

  I had this problem since, I believe, Mavericks. I don't think that I had the problem with Snow Leopard.

  I use the classic layout in Mail.  This problem is to click on a message to read the email. New content look a popup appears generally, which is a duplicate of the message content area. It will usually take the whole screen, blocking my view of the list of e-mail. It does not occur with every email and is very irritating when this happens, which is most of the time. I don't see anything in the menus to stop this behavior.

  I do not believe that this outlook. I think now to switch to Outlook, because I'm tired to happen.

  Is it possible to stop the content of the popup display screens e-mail? Thank you

  Emails are opened in windows separated only if you doublecklick on them. To display it in the window of Mail, simply select an e-mail in the preview window.

  Even if you open an email in a separate window, you can change its size by dragging on the edges of the window. The next email will then open in the same window size and in the same place on your screen.

• How to reverse 'Ongoing Acquisition' - Signal (Pike F421B)

  Hello everyone,

  I am currently working on a machine to control tree cam using the Pike F421B. Before I used the Smartview AVT software. Now my company wants to change for LabVIEW, because we have developed our own analysis program. During the image acquisition process exits camera has "occupied" - signal. My question is: is it possible to invert this signal somehow. I was able to reverse in AVT Smartview but I can't seem to find settings in LabVIEW. This signal is used to trigger LEDs sequentially so that the acquisition of the lighting and the image is synchronized. The problem is the LED controller reacts to the front down a trigger. That's why I need to somehow reverse that signal without external wiring. I currently use the VI "vision acquisition." I would be grateful for any solution. (See also photo).

  Thank you.

  I assume you mean that the camera came out of this signal by means of a line of input/output, correct? You should probably use some access to the registry to configure this. If you check the manual of your device it should list the records, you must configure and you can then use the registry read/write IMAQdx screws to access.

  Another option would be to use an AVT software and save the default settings of this I/O reversal signal in slot voltage by default the camera. Since it is not affected by default IMAQdx framework is broad, it should keep this charged setting even after IMAQdx substitutes parameters with what you saved the VI or MAX Express software.

• Ongoing problem with my Netgear WiFi adapter and hardware software.

  Please help me solve this problem, which still exists.  I even once contacted NETGEAR, but they say it's a problem for six months and it is only cosmetic in that the adapter Netgear WIFI does his job, despite the failure of the adapter Netgear WIFI Wizard appears immediately except to re - install via CD Netgear...  Read on: Although my new Netgear dual-band "N" WIFI ADAPTER works optimally and, out of curiosity, I have re-installed several times using the accompaniment CD... there is a small problem I want to solve: when I click on the WIFI adapter desktop ICON, I get a window of PSI with the message "FAILURE of SERVICE.  Yet once, WIFI actually moved and is also indicated under the programs/features and works perfectly well.  When I bring up the icon under all PROGRAMS, the same result occurs: the same message reappears: "FAILURE of SERVICE.  When I called Netgear to the Philippines call center, support staff of so-called tech advised me to ignore the message and that I was the first caller on this issue, "as long as the WIFI adapter gives you the desired signal quality and speed, just ignore... "When I pressed on others, a supervisor at the call center told me that she would pass on the information that I provided to their engineers to study the problem.  In addition, the supervisor told me that no one had contacted the Center to call on this particular issue.  Yes, I even disabled the built-in WIFI adapters (Atheros), but the 'problem' in question still exists.  Please note that it is a phenomenon of long months and that in the past whenever I clicked on the ICON, the regular Netgear Windows would come upward, including the various hot spots in option, etc. I even updated the software successfully and rebooted the laptop, according to Microsoft's Windows Update instructions.  Please let me know what is happening and how I could fix this ' cosmetic ', if that's what it is, according to Netgear support.

• Someone out there who has an ongoing problem with 7 refusing to print, even after that the driver was abandoned and re-installed?

  I have a Toshiba laptop that runs Windows 7 with an HP printer 6 L. I am running Open Office 4.0.0 and the latest version of Adobe Reader. To date, that the system is undesirable! The 6L display test endless pages but refuses to print anything out of system 7. I dropped 6 L Driver, registry & file cleaned up and optimized the system and then reloaded the driver off of the HP site but the system refuses to print. I even went up to turn off the printer for more than 24 hours to try to get the printer to the reduction in the memory and empty the memory to zero to try to kickstart the printer to pick up the 7 material systems. Up to present all this for nothing. 6L memory is fixed at 1 024 Ko and the document larger than I tried to print has been 136 k so the memory capacity must be nothing. Anyone, anyone, outhere who can help, please. I'm ready at this stage to give up the printer with an AX, since it is now beyond the frustration and get into madness! I must also stress that the 7 system also creates a (1 copy) in the printer Panel. There is no need too!

• How to extract the layers form a PDF (previously built with Amnesty International)

  Hello

  Unfortunately, I saved a whole website in PDF format design without checking "editable possibility."
  = > Oops

  When open my file pdf, illustrator ask me to choose only a single page.

  
  
  

  I thought that I would never be able to change as long as when I click on the Visual, nothing happened
  

  but I realized that I could still isolate group

  and then isolate layer, then finally an object.

  

  I would like to leave this 'clip' mode and get back to my good old layers
  Is this possible?

  
  2 questions
  How could export all these layers 'merged' into good layer, to be able to change my big file?

  How can I export my pdf into a good .ai file again?
  Is this possible?

  Thank you very much

  Marguerite

  You can release the clipping mask, but will give you all the layers back automatically. Some objects and the effects could also be extended.

  You should always save the file TO fully editable character.

  From the PDF file, you can only manually things sort in a layer structure

• extract data from a string and compare it with sysdate

  Hello

  Since a few days I struggle to find a solution to my problem, maybe I have some luck here.

  Data type:

  11/23 ANA

  Alex 19/11

  1/11 tomorrow

  03/12 FW1

  Makes me tomorrow

  Bo 11/12

  Necessary data should be as MM/DD. I used substr and/or regexp_like, regexp_substr, but having a few problems.

  Months can be like 1, 2.11, 12 or 01,02, 03... 11, 12.

  I don't need the data in the format Month\Day.

  Basically all of the above "/" should be a month.

  And I need to get out all the foregoing, > 13.

  And I need to compare the exp with sysdate.

  Any ideas?

  something like:

  in_format IN VARCHAR2: = ' MM/DD')
