MAX is unable to detect the webcams

I have three different webcams. Two of them worked in MAX and LabVIEW. When I tried to install the third argument, everything stopped working.

I think the problem was perhaps a database corrupted - I received the following error message:

http://digital.NI.com/public.nsf/allkb/7FF79722720AEE488625759B0074A2CA?OpenDocument

I followed the steps listed on this page, which did not solve the problem.

I then reinstalled MAX and LabVIEW, and this has not solved the problem either. Or MAX no LabVIEW can 'see' one of the three webcams.

All three are standard webcams and should be detectable by LabVIEW. I use LabVIEW 8.6 with Vision Acquisition 8.6 and IMAQdx.

Webcams are all series:

-HP Webcam (integrated in the laptop, not sure type bus)

-Logitech Quickcam

-Microsoft Lifecam

The three cameras work on this computer - they work very well with their Aboriginal viewers. The first two worked fine before LabVIEW.

Is there a way I can * force * MAX to recognize these devices?

Vision acquisition 8.6 does not support DirectShow/USB cameras. Which has been added in 2009. I'm guessing that you have a newer version already installed? I would say go and grabbing the latest version here:

    Hello, I have been using this machine for the past three years on Skype and video chat worked well. All of a sudden it says it cannot detect a webcam (its a webcam integrated), but I have used other sites to make sure that it works. I have closed Skype and restarted it and many other things. What can I do? It is the only way of me and my fiance can meet that I need a quick fix.

    Dear forum,

    I am new user of the Satellite L655... I just got about 1 month ago. I don't know why, but I can't use my webcam. Whenever I try to use it for Skype or yahoo messenger, it cannot detect my webcam.

    Is something wrong, and what should I do? Can someone help me solve this problem?

    Thank you for your help,

    Best regards
    Yogi...

    Hey Buddy,

    What happens if you start the webcam software? It recognizes the webcam?
    Important point is that if you want to use the webcam with Skype or other programs, webcam software shouldn't start because the two programs try to access the webcam. So close to first the webcam software.

    Last but not least, I would recommend reinstalling the driver from Toshiba Web site:

  • Linksys wireless-g usb network adapter unable to detect the router using windows XP desktop PC

    I've changed in broadband Orange yesterday and since then my adapter is unable to find the network (it was working fine with TalkTalk until I changed).

    He managed to find a couple of other networks that are nearby but nothing else.

    I have a laptop (windows 7) who finds the router Orange immediately. I tested the adapter with the laptop and it finds the router Orange plus about 10 other nearby networks.

    I rang Orange who crossed their tests and not found any problems. I uninstalled and reinstalled the adapter on the windows XP desktop, but I get the same result.

    Can anyone help?

    Thank you

    Thanks for the reply.

    I got it finally work last night after a day of cleaning up!

    Even if the network does not have to be detected in the available wireless networks "choose" I tried the "New Connection Wizard" and entered all the details that came with the router. The adapter found the Orange router but nothing else in the region.

    For now, it works but there is a problem somewhere, because I don't see any networks, I can see on my laptop.

    See you soon.

  • WRT110 Wireless - unable to detect the signal/connection.

    Recently lost connectivity to an existing wireless connection I had set up over the past months.  The two XP laptop with Dell Wireless WLAN Card and box of Wii is no longer connect or detect the signal.  Curiously, WiFi stood momentarily after the reset of power on the router but then disappeared. I connect well with connection wired and mobile detects all my neighbors SSID.  All the lights on the router are bed... but no wireless signal.  I even joined a wireless USB device to my desktop pc to test.  It detected all the SSID of the neighbors but not mine.  Even with the laptop.

    Troubleshooting steps I did:

    -Router-

    Power recycled.

    Held reset button.

    Linksys firmware to 1.0.5 update

    Configuration is modified to enable the SSID Broadcast

    -Laptop-

    Card driver WLAN Dell upgrade vA17 4.170.5 to 4.170.77.18 vA22

    People with disabilities Dell Wireless utility and enabled Windows Wireless configuration.  Either the Dell or Windows detected my wireless signal wireless utility.  Both will detect AND connect to the open connection of the neighbor.

    Appreciate any idea or other troubleshooting suggestions.

  • 4 iPad unable to detect the C4599 already connected to the wireless network printer

    Hi all, I have a C4599 All in One Printer. I have just set up successfully with a WiFi connection to my router / modem network (infrastructure mode). There is no error message and I can print from a variety of laptops Windows (XP, Vista and 7). I loaded the HP eprint app on my Ipad 4 but it can not detect the printer. Note that the HP site says that this printer is compatible with the App ePrint.

    A second and possibly related is that I recorded with the HP eprint service website but I can't get the code or e-mail address for my printer. I can't find any way to turn it on the Web Services on the printer? (The HP site says this should be under Setup > wireless to the printer, but it is not.) There are only options to turn on/off the wireless, testing the wireless and print the wireless network and printer settings (which are all OK > PASS or information).

    Any ideas?

    Thank you

    With the update that has been done to the ePrint application, some of the old printers lost the ability to use this application to print from. The printer would not print directly from the iPad to the printer either. This is a feature called AirPrint. When you have the possibility to use AirPrint, he must place the unit on the same network as the printer, pull up a photo, press the action button on the iPad and then select print. The iPad will then give an option of the printer to print from if there is more than one printer capable of of AirPrint on the network.

    The printer cannot produce a code to register and save ePrint due to the age of the printer. Printers that have the ability of ePrint are a majority of those who have been in production in 2010 and later versions. A few Photosmarts who have the ability to use ePrint AirPrint are the 7520,6520 and the 5520. To learn more about these printers, see this link here.

  • Unable to detect the rotation of the device of the method of sublayout of screen

    I'm developing an application compiled for OS 4.5. I need to find a way to detect the rotation of the unit and again fill the screen so that the fields are arranged according to the new dimensions.

    My idea was to save the display width and height in some private variables in my case screen and method of sublayout overloaded screen, check if the new values have been changed.

    What happens is that I get the old width and height again and again.

    I first read this post. In this document, @arkadyz points out how the order of the calls is a little weird and values returned by the view class are updated after sublayout is finished.  Therefore, there is no way to detect by the sublayout method.

    The proposed solution is to check the dimensions of the display within an invokeLater. Here's my test code:

    public class TestScreen extends MainScreen {
    
        public TestScreen(){
            super(Manager.NO_VERTICAL_SCROLL);
            populateScreem();
        }
    
        private void populatescreen(){
            deleteAll();
            //fields and containers added here. No need to add any to observe the issue.
        }
    
        public void sublayout(int width, int height){
            super.sublayout(width,height); //Tried calling this in the last line as well with identical result.     
    
            System.out.println(">>>>>>>>> Display.getWidth(before): " + Display.getWidth());
            System.out.println(">>>>>>>>> Display.getOrientation(before): " + Display.getOrientation());
            System.out.println(">>>>>>>>> Width argument value (before): " + width);
    
            UiApplication.getUiApplication().invokeLater(new Runnable(){
                public void run() {
    
                    System.out.println(">>>>>>>>> Display.getWidth(later): " + Display.getWidth());
                    System.out.println(">>>>>>>>> Display.getOrientation(later): " + Display.getOrientation());
                }
            }, 1000, false); //Playing with the time parameter does not change behavior.
        }
    }
    

    This gives exactly the same results. After that, I came to this post where @peter_strange

    provides a solution based on pushing a dummy screen, which detects the new width and height, and then passing the new values to the previous screen. I also tried, but it didn't work either.

    I also tried using the obsolete Graphics.getscreenWidth instead of Display.getWidth, and it did not work.

    Now, I am out of luck because I have almost tried everything and I can't provide a solution without resorting to the 4.7 or 6.0 API.

    Tested in BB 9550 Simulator v5.0.0.535 (Platform 2.13.0.108) and v5.0.0.306 real unit BB 9520 (Platform 4.2.0.113)

    Take a look at the following.  In my view, the following code can be used to detect changes in orientation.

    public class TestScreen extends MainScreen {
    
        int currentDisplayWidth = Display.getWidth();
        int currentDisplayOrientation = Display.getOrientation();
    
        public TestScreen(){
            super(Manager.NO_VERTICAL_SCROLL);
            populatescreen();
        }
    
        private void populatescreen(){
            deleteAll();
            //fields and containers added here. No need to add any to observe the issue.
        }
    
        public void sublayout(int width, int height){
            super.sublayout(width,height); //Tried calling this in the last line as well with identical result.     
    
            System.out.println(">>>>>>>>> Current sublayout width (before): " + currentDisplayWidth);
            System.out.println(">>>>>>>>> Display.getWidth(before): " + Display.getWidth());
            System.out.println(">>>>>>>>> Display.getOrientation(before): " + Display.getOrientation());
            System.out.println(">>>>>>>>> Width argument value (before): " + width);
            if ( Display.getWidth() != currentDisplayWidth ) {
                // process orientation change
                // ....
                // Now reset change detection variables.....
                currentDisplayWidth = Display.getWidth();
                currentDisplayOrientation = Display.getOrientation();
            }
        }
    }
