Webcam problems with windows 7 profesional (64bits) RTM

hello the reason why I write this post is because last week my laptop model pavilium dv3-2155mx I put the windows 7 Professional (64 bit) RTM, everything is going well but the only problem is I can not use the webcam , windows 7 is the default options when download the drivers and see if the driver of the webcam is installed appears to me as if I were in the device manager under 'imaging devices'. The problem occurs when I open the "HP MediaSmart Webcam", to open that program should be off the camera from my laptop and see the image that is generating the webcam but the following appears:
"MediaSmart Webcam can not make the connection to the video device (HP Webcam). Select another capture device in the closed configuration options or applications that may be using this video device and restart SmartWebcam"
I do what that tells me there but nothing ... again receive the same message also tested with the "Cyberlink YouCam" and leaves the same, the same happens when I try to put it on Messenger, getting an error that can not start the webcam ... I would like to know what is happening and give me a solution for this problem because the windows 7 looks great and I do not want to go back to Windows Vista because Windows 7 is much faster and much better job with this, want a solution please to use my webcam in windows 7 I hope your answers thank you very much!!

oops sorry, my mistake, well the exception says "System.NullReferenceException"
the code:
string oradb = "user id=" + login + ";password=" + password +
";data source=(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)" +
"(HOST=" + ipServer + ")(PORT=" + port + "))(CONNECT_DATA=" +
"(SERVICE_NAME=" + bdName + ")))";
OracleConnection conn = new OracleConnection(oradb); <---------------------------- here the error start
OracleConnection conn = new OracleConnection(oradb);
try
conn.Open();
return conn;
catch (OracleException ex)
switch (ex.Number)
case 1:
throw new ArgumentException("duplicate data");
case 12545:
throw new ArgumentException("not database available");
default:
throw new ArgumentException("Error: " + ex.Message.ToString());
catch (Exception ex)
throw new ArgumentException(ex.Message.ToString()); <----------------------------- error: "System.NullReferenceException"
I hope this be more clear, Oracle works on Windows 2003 Server rc2, ver. 10G

  • The same problem with Windows Vista 64bit-iTouch not recognized by iTunes

    Happy Holidays, all. I was just hoping that someone had come up with a fix to the problem with iTouch and Windows Vista Premium (64bit). All I get is a picture of the plug pointing to the iTunes image on my iTouch, can't even see the regular icons yet. The device is not picked up by iTunes, either. Tried reinstalling iTunes, the whole bit. Thought I'd try one more time to get a fix before returning the product. By the way, if you ever finally do get through to Apple Tech Support, they'll act like they have never heard of the problem (at least the guy I spoke with did. He wasn't very nice or very helpful). Anyway, good luck and thanks.

    I have I think the same issue. iTunes can see a Nano but not an iTouch. Vista see the device when I plug it in, but no luch with iTunes. I ended up using a old laptop with XP which is slow and out of hard drive space, so I need a fix.

  • Ideapad S10-3 Webcam Problem with Windows XP

    Hi folks,
    I own a Ideapad S10-3 shipped with Windows 7 Starter.
    Because Windows XP is much faster on this machine, I installed Windows XP Professional SP3.
    After Installation I downloaded all S10-3 Windows XP drivers available at the lenovo site for S10-3.
    No installations problems so far, the webcam was working and recognized as Lenovo EasyCamera
    Vendor ID: 5986 Product ID: 0190 Rev: 1409. Driver Provider is displayed as "Vimicro"
    After a few days using the netbook, one day i started windows and the new hardware found wizard started and recognized a new USB Video device and installed the UVC driver from Windows. This "new" device has Vendor ID: 0ac8 and Product ID: 3450 Rev: 0130. The old webcam with the old IDs isnt shown anymore in the device manager. (only if you set var "devmgr_show_nonpresent_devices=1" and enable "show hidden devices")
    When i try to use the webcam the light beside the webcam turns on, but no picture is displayed. No matter which program i try, the webcam isnt working anymore.
    Because of the different device ID it isnt possible to install the lenovo webcam driver, but basically the webcam should work with the UVC driver provided by windows. I find it totaly strange that the webcam is showing up suddenly with a different device id.
    When windows is running theres an process VM322_STI.exe running, its part of the Webcam driver and gets installed.
    This is the second S10-3 Netbook on which i have this problem, i returned the first one because of this problem.
    Is someone here, who is also using the S10-3 with XP or has an similar problem ?
    EDIT: I read about the firmware update problems/issues with the old S10 models, but theres no Firmware on the S10-3 website i think, so i didn't think that i accidently flashed a wrong firmware to this webcam. I only used the Device manager to install the webcam driver. Or is it possible that the firmware is included in the driver package?
    regards
    RaiHei

    IT's working again... very strange ... the driver on the lenovo site for this webcam seems faulty, i uninstalled it, and after the reboot the old cam with the old device id is back in the device manager ... i now use the uvc driver and NEVER install the lenovo driver again... just because of the driver i returned my first s10-3 .
    Also very interersting: After the cam didnt work in Windows XP anymore, i recovered the original Win7Starter from an complete hdd image (which i made before installing win XP) and in Win7 the cam wasn't working too. Because of that i never thought that it was a driver problem, because the driver and windows xp was deleted when i recovered the original win7.
    so my recommendation: DO NOT install the lenovo driver, let Windows XP use its own UVC driver.

  • Hp pavillion dv6700 webcam problem with windows 7

    I have hp pavillion dv6700, which had Windows Vista originally. I upgraded to Windows 7 and the webcam doesn't work amymore. When I launch Cyberlink Youcam, i get message " No video detected, please install camera" I have updated BIOS and all windows update and nothing works. "Image Device" in not shown under device manager.  Please help

    Hello Abzozo1.  I understand you're getting the "webcam not detected" error.
    What is the exact product number of the notebook?  This document can show you where it is located.
    Has the webcam ever worked since you upgraded the operating system?
    To ensure that you have all of the software installed properly I suggest installing the HP Software Framework and HP Support Assistant.  You can then run HP Support Assistant and it will automatically install any missing software.  If that doesn't resolve the issue I suggest you take a look at my thread located here.  This thread covers the common solutions to this error.
    Take a look at that thread and let me know if any of the steps help.
    Have a great day!  I'll keep an eye out for your next reply.
    Please click the white star under my name to give me Kudos as a way to say "Thanks!"
    Click the "Accept as Solution" button if I resolve your issue.

    Driver problems with Windows Professional XP 64bit Edition

    Well, after looking around the forum here I found an answer that works! I wish I could remember who to give credit too though. I installed the latest Vista drivers and I got static all the time. I tried another members suggestion of disabling the X-Fi device in the Device manager every time I log off and then enable the X-Fi the next time I log in. I have great sound as long as I do that. Also, for connecting to a home system I am using the DTS-60, $00 on this website, but it works well if you havea DTS decoder. I am using the X-Fi extreme Music edition. Good Luck, hopefully another driver is on the way.

  • MediaBox problem on Windows 7 64bit

    Hi,
    I've noticed problem with MediaBox on 64bit Windows 7.
    Several month ago everything worked properly - I didn't program it but check on the website: http://javafx.com/samples/MediaBox/index.html (*)
    Today I've tried to experiment a little with MediaBox, and I've started to build an application described there: http://javafx.com/samples/VideoCube/index.html it didn't start nor in browser nor downloaded and compiled locally. The error during execution was as follows:
    java.lang.UnsatisfiedLinkError: com.sun.media.jmcimpl.plugins.directshow.DShowEngine.ndsInit(I)Z
    I've checked the link (*) but it failed too.
    I've made checks using both 32bit and 64 bit JVM's installed on my machine but without any success.
    Any help?
    Kuba

    Well, a link error is generally thrown when Java cannot access some native library binding, but you probably already knew that. I've checked Google, and although I have seen people with similar problems, I haven't seen any viable solutions. I checked JIRA and the quick search did not reveal any bug reports describing this. Maybe you could file one: http://javafx-jira.kenai.com/
    In any case, the rumors say that JavaFX 2.0 public beta will be coming next month and it apparently includes an all new media stack. Maybe you'll get lucky and it won't be an issue then. Windows 7 is still significantly less popular than Windows XP, so I'm sure your project can survive in the mean time.

  • Itunes problems with windows 7 64 bit

    Hi, i have searched and searched for a solution to my on going problems with itunes on my windows 7 64bit computer.
    it started with my backups not being saved when i sync, then any music i add seems to play strangely i.e skips and plays the start of the song in the middle.
    updating last sunday to the new iphone os (4.3) was also a disaster, having to try a number of times over 2-3 days as the downloads just seemed to hang and not do anything. At the end on around my 10th try it downloaded and updated in around 15 mins.
    I now find myself when i connect to itunes more often than not having to manually delete corupt backups until i get a succesful one as sometimes it works and other times it doesnt.
    I tryed a vista computer a friend has and everything worked perfectly!
    songs, backups the lot!!
    So it clearly seems like a problems between windows 7 64bit and iphone 4.
    can anyone please shed some light on these issues??????
    Many thanks, gaggie...

    I am not sure that I can help with this, but I have seen an instance where continuous backup software cased playback problems.
    Also are you using any Norton products?

  • Is PE7 compatable with windows 7 64bit?

    are there any versions of Adobe Premiere Elements besides PE8 that are compatable with Windows 7 64bit? I have heard of lots of problems with PE8 and I would prefer using PE7 if possible. Actually I use PE3 with XP home 32 bit and love and don't really want to upgrade but it seems like i might have to. thanks

    i downloaded the PE8 trial and have worked with it for a couple of hours and had only one glitch so far. while capturing it froze after about 10 minutes, i had to capture the rest and splice it in. i added some titles and a 2nd audio track that was mono and used audio effects to copy left track to right track, i faded in video and audio and so far everything seems to be working fine.
    i have an intel MB  D975XBX2
    dual core processor,
    4 gigs of RAM
    win7 pro 64bit
    it's taking a little getting used to but probably not as hard as trying to learn a whole other program like sony studio for example. i've got 30 days and i'll keep using it and see how it goes but so far, so good.

  • X200 with Windows 2008 64bit

    Can someone give me some hint on how to resolve this issue?
    I bought the X200 and installed Windows Vista 64 bit without a problem. I am now creating a VM with Windows 2008 64bit but received this message after installation and reboot: "Attempting to load a 64-bit application, however this CPU is not compatible with 64-bit mode."
    The CPU is Intel P8600 which is 64-bit compatible. Why did Vista 64-bit install and run properly and not Windows 2008?
    Thanks !

    I found the answer to my question on this blog...
    http://www.aspdeveloper.net/Virtual_PC/rn-739-53140_Does_VPC_support_64_bit_OS.aspx
    Basically, yes with VMWARE only, not MS VPC...

  • HelpPane.exe automatically starts with Windows 7 64bit.

    HelpPane.exe automatically starts with Windows 7 64bit.  I have to start task Manager and disable it or else it keeps popping up.  I cant find where to disable this service from startup.  Please Help.

    Hello
    I found a simple yet effective solution for this problem, my friend had the same issue so instinctively as a technician, I suspect this was a malware of somekind so I re-formatted and installed Win7 funny it's still there, so I did a Hard disk wipe using
    Dalvik's and re-partitioned and formatted again, to my surprise it still have the same problem.
    So I ask Mr. Goo' old Mr. Google for answer, but I've found more complications, sorry for the story, so without further a do, the solution.
    Boot to safe mode. (may also work in "normal mode")
    Go to Task Manager>
    Click the Services Tab>
    Right click "HelpPane.exe" or Help and support service>
    Select Properties>
    Click the Security tab>
    Click the Advanced tab (for permissions options)
    Then select the "permissions entries" one at a time>
    Click Change Permissions>
    Then click Edit>
    CLEAR ALL THE CHECK BOX FOR ALL ENTRIES
    This should prevent access to the HelpPane.exe to all users/programs.
    This resolved my friends Windows 7 "Help and Support thingy" issue, hope it does yours too.
    Message me for questions and/or clarifications/corrections.
    Thank you

  • WET54GS5 with Windows 7 64bit

    I would greatly appreciate some help with getting my WET54GS5 Wireless Ethernet Bridge to work.  I just got a new computer with Windows 7 64bit, and at the same time installed a new Linksys E3000 Wireless Router.  I would still like to use my existing WET54GS5 to work, but am having difficulties.
    First, I do not have the Setup CD any more.  I have searched vigorously on the web, and can not find it anywhere for download.  Could some kind soul please zip up the disc, and make it available for download?
    Second, I did try to access the bridge directly with the 192.168.1.226 address, but that did not work.  And I did try the Reset procedure numerous times.
    I know that new versions of the Bridge are available, but they only have one port available -- I need three.
    So, many thanks in advance for any help, particularly if anyone could make the Setup files available.
    Best regards,
    Nick P

    Answers for both questions,,
    First original
    To connect directly to the
    WET54GS5 you must make alterations in the adapter settings of the computer,,, since the bridge is almost like a funky switch you will have to adjust the computer adapter manually to IP 192.168.1.90 and click the subnet box to autofill that in than just apply that. close out and you should be able to access the manual web based aplication. Make sure to set computer adapter back to auto obtain IP once you finish. doh just saw previouse post http://www6.nohold.net/Cisco2/ukp.aspx?vw=1&docid=6bf4ec9e5c6e44618af5f50f91c49c59_4894.xml&pid=80&r...
    The other question reguarding using one of the WET adapters and connecting a switch I am doing that right now and it works perfectly,, although it does create a extra network device to appear within the main network so some computers think there is multiple networks.. a little annoying but not a serious problem. Mainly only with older computers like XP

    Your system doesn't meet the requirements and that is that. AE has required 900 pixel height ever since CS4. Other than changing your screen res or shuffling around windows there is nothing you can do.
