Alternative to currentStateChangingTransaction on Windows

Hi again
we are struggling with our custom Windows store.
because the method 'currentStateChangingTransaction' isn't available on a Windows platform, we cant figure out how to check or affect the transactions in progress on a folio.
this means if we stop a fulfillment mid-download, we cant 'see' that its half downloaded, we also cant continue the download, or archive the folio.
is there perhaps some Windows specific sample code we could use? we have searched but not found any.
maybe someone else has found a clever work-around?
any help appreciated
thanks,
vauneen

hi, we are still struggling with this.
we'd appreciate any ideas
is there any way we can force a folio or transaction state, like manually change isArchivable from false to true? so we can delete the folio and restart the download?

  • Alternative trackpad driver for windows is coming

    creators of powerplan7 (boot camp keyboard backlight disabler) announced an alternative windows driver for the apple multitouch trackpad
    sounds so promising. oh lord this is what I've been waiting for since '08.
    folks does anyone participate in beta test program? I already wrote an email to them but no response for > 24 hours. I believe they're getting too many emails. so is there anyone who have had a luck to try it out?

    I am afraid that the P1102w's driver has been checked-in MS OS, I guess what happened on your Windows XP computers is somehow the driver has been pre-loaded on it. Back to your question on Where can I find the driver for Windows 7 64, there are several ways,
    1. Smart Install printer by printer - when plug-in USB cabel to your PC, the driver installation instruction should be able guide you install the driver
    2. Use the CD in box
    3. Please go to hp.com to download the proper driver for Win7 OS.
    Hope it helps.
    I am an employee of HP but I only speak for myself and not for the company.

  • I want to dual boot windows 7 and Arch with an HDD caddy.

    I am thinking of two possiblities with this scenario.  I want to first leave my windows 7 install on the hard drive that came with my laptop, and leave that HDD where it is, but in a few days, i'm getting a caddy so i can switch my optical drive for another HDD, which is going to be a 250gb.  On the 250, i want to experiment with arch, and maybe other linux distros, so i can get a nice feel for linux once again, it's been about 2 years since I've played with it.  What i am hoping to maybe do is switch those hard drives out, if I can get a linux install i feel 100% comfortable with, and running the windows HDD in the caddy, and the linux HDD installed in the motherboard.
    I just have a few questions though.  First, is it possible to boot Arch when it is an HDD caddy? and second, would windows possibly work if i moved that hard drive into the caddy later?

    Yes, and yes.  Both should be quite easy.
    You should be able to set you BIOS to boot from one or the other - or alternately you can chainload windows from a linux boot loader quite easily (if/when linux is on the drive that the BIOS has selected to boot).

  • Ipod 5G with Windows 98

    Can i use my ipod 5G with Windows 98
    Thanks.

    The iPod is designed to work with iTunes and there is no version of iTunes that works with Windows 98. There are alternative iPod managers for Windows such as Anapod, XPlay or EphPod but they do have a few major drawbacks. The iPod software updater is integrated into iTunes 7 so .....
    1) You can't update the firmware on your iPod if a new version comes along
    2) if there are any problems with the iPod you can't restore it's firmware to fix them.
    3) If purchasing iTunes Music is something you wanted to do you won't be able to buy from the iTunes Music store.
    Staying with 98/ME, you may also require drivers, there is a link in the Anapod page to suitable iPod/USB drivers

  • Completely random restarts (windows + linux)

    Hey,
    I put together a system (see sig) for a friend, anyway they started complaining about random restarts using winxp (with or without either service pack). Cutting a long story short, we RMA'd the motherboard, got a replacement, and the problem persisted.
    Basically this is a list of things that has been observed to happen
    1) Randomly reboots during winxp install (not connected to the internet, harddrive virus free did a complete scan and alternated b/n linux / windows installs, ie filesystem changed -> no virus)
    2) Reboots under windows randomly, can be when surfing the net, ripping cds (this is the best test to make it happen), or just sitting idle (went to get a drink and it had done it). I tried to disable the "Automatic restart on fatal error" in the advanced settings thing, that did nothing, so im fairly certain that its a hardware issue after that.
    3) Reboots during Gentoo Install (I figured I should stress test it), the reboots occur at different places depending on the settings changed, and detailed below, but inevitably it always reboots.
    4) Occasionally winxp will fail to load, or givea a BSOD before rebooting, but this has happened maybe 5 times in hundreds of random restarts, the error messages are not in reference to anything in particular, nor could I garuntee the ability to get a copy of one to show you.
    I spent most of yesterday digging around these forums reading suggestions etc...
    The following is a list (i took notes) of what I have tried (this is long I know, im sorry)
    1) Different PSU
    Originally the PSU was the stock standard that came with the sonata http://www.antec.com/specs/true380_spe.html which at 380W seemed a little low (this was before reading forum posts), so replaced it with the one in the sig -- Not a PSU problem.
    2) Different RAM
    Figured since a second replacement board had the same problem it could be the RAM, tried RAM from my machine which I know is working perfectly, reboot as normal. Hmm so I did a memtest86 scan on the memory left it running 48hrs, that lets memtest86 loop about 7 times (for anyone interested) there was not a single error. -- Not a RAM defect.
    Started reading forums here
    3) Different Harddrive / Optical Drive
    Tried a 120G sata maxtor drive (which I know works), reboots persisted.
    Tried a DVD-ROM, from my machine, reboots persisted.
    4) Measured the voltage with multimeter, all voltages were within 1% of the spec.
    5) Put some thermal (arctic silver 5) compound on the cpu / heatsink, but the temperature under stress test never goes above 51 degrees anyway. Not at all out side the operational conditions for a P4 3.0.
    6) Ram Timings / placement
    If I leave as SPD, reboots occur more quickly, setting timings to 2.5-3-3-7 burst 8 gives me longer until the reboot occurs, however it still eventually occurs. I have tried running the ram in single channel mode (with both sticks in the same channel), dual channel mode 1 3 and 2 4 have been tested, and by only having one stick in at a time (
    7) Ram voltage
    I kept alternating b/n SPD and the above timings as I moved the RAM voltage 2.60 - 2.65 - 2.70 - 2.75 (I haven't gone any higher yet as thats the red zone, ie 2.80), the best times I experienced for a gentoo install were with 2.70 / 2.75 however after 20 to 25 minutes of compiling the machine restarts. I couldnt get the machine to restart ripping cds on this setting, but thats probably because I lost interest in ripping over and over again after the 5th time, I did get to 10th rip once, only to have it restart.
    8) Clock Frequencies
    Tried setting FSB to 201 (as some threads recommend), didnt help. Tried setting RAM speed at 266, 333, 400, and auto, the lower the speed the longer until a reboot, but only a minute or two is gained by 266 over 400. All this is done on the NORMAL (meaning SLOW on older boards) setting.
    10) Video card
    Originally there was just some old PCI card I had laying around in the machine (lack of money), however now (see sig), either way reboots occured, the video card was my 3rd suspect, motherboard, ram, video, psu, .... etc...
    Thats it.
    Now, I saw some people commenting (when I was reading the threads) that they wondered if this batch of boards was bodgey, no one seemed to want to agree, however after trying suggestions from over 100 threads (do a search for random reboot if you dont believe me) and not actually getting any success, and having had this happen over TWO of the SAME board, im really beginning to think that is the case. Some of the search results were PSU based, granted, so lets knock off 50% that leaves about 50 cases of this incident which haven't actually been resolved.
    Im not playing blame game, it just seems very likely to me, but if someone gives me a solution that works, ill appologise profusely, and go and buy the MSI K8N Neo2 Platinum that ive been wanting -- but to scared from this situation, to actually buy.
    This problem is remarkably similar to Random PC reboot this, except im not able to actually produce the windows errors as noted at the top.
    So... Please HELP !!!!!

    1st of all, kudos to you mate, now this is the proper way to ask for help!  
    but looks like you've tried everything other than hitting it with great force with a piece of 4 by2.
    only thing i can ask is if you've tried increasing the vAGP in bios, this doesnt really increase the voltage to your agp (well, it does) but more to the point, it increases the voltage to the motherboard chipset. you've mentioned that youve put as5 on the cpu, it might be worth trying a clean and application under the northbridge too (though they do coat it with some cr@p so much its a bit of work sometimes getting it all off)..
    another thing, though this shouldnt help, is to try increasing the vCore to the cpu just a tad, most intel boards' voltages vary a fair bit, some say its due to a special functionalities withing the processor itself, but most say that this hasnt been implemented.
    other than that, best of luck to ya
    p.s. or you could go get a cheap 865 board as a replacement, i wouldnt upgrade to a64 yet with nforce4 (nvidia) + xpress200 (ati) mobos just around the corner as well as 90nm a64 processors with sse3 instuctions too

  • Help with installing Windows 95 on Windows 7 64 bit Home Virtual PC

    I apologize in advance.  I am new to using Virtual PC and I don't understand what I'm doing wrong.  I am trying to create a virtual Windows 95 on my Windows 7 Home 64b computer in Virtual PC.  I have the original W95 cd, and I was able to
    create a Win95 boot disk.
    What I've done so far is:
    Create a Virtual drive in VPC.
    Attempt to install W95 using the cd.  The virtual system didn't install it.
    Created a W95 boot disk using a USB floppy drive.  The virtual system doesn't seem to access the USB floppy.
    Tried to enter the BIOS menu in the virtual drive and set the floppy as the initial boot drive.  The system doesn't access the floppy.
    Please let me know if you need any more info to answer this question.  Thanks!
    RK

    virtual machines won't detect usb floppy drives
    (you might also run into issues trying to install win95 on a 64 bit system not sure though)
    what you need to do is create a floppy image first
    Also use VMWARE player for win95.. virtual pc doesn't work well for it in windows 7
    so if you want to create a floppy image
    first download magiciso (it's free)
    go to new - floppy - 1.44
    copy the files from the usb floppy onto the newly created image
    save it
    now go to the image in your browser and change the extension from .ima to .flp (for VMWARE) or .img (for virtual pc)
    now you can mount the floppy image instead of using the drive all together :)
    here's an alternative method for installing windows 95 on a virtual machine as well
    installing windows 95 and CD driver manually without the floppy setup disk
    what you need:
    .DOS on a floppy or on an image (.flp .img)
    .Windows 95 cd
    .VMWARE player (it's free) or virtualpc (I recommend VMWARE)
    .Magiciso (the free trial version will do)
    .a copy of MSCDEX.EXE and oakcdrom.sys (both can be found online)
    step 1
    create a new virtual machine (make sure to add a floppy image drive if you are using vmware)
    step 2
    put your dos floppy/image in or mount it and install dos
    step 3
    download and install the free version of magiciso
    open magic iso
    go to new - floppy - 1.44
    find a copy of mscdex.exe
    find a copy of oakcdrom.sys (generic cd rom driver that works with dos.. might have to try another if it doesn't work)
    RENAME the oakcdrom.sys to cdrom.sys
    drag both these files into magic iso on the floppy disk we just created
    save the file
    close magic iso
    find the file we just saved in your explorer
    change the extension from .ima to .flp (if you are using vmware) or .img (if you are using virtualpc)
    (if you can't see the extensions you're going to need to change your folder options to show extensions)
    google it. it's easy to do
    step 4
    go back to your virtual machine
    mount the floppy image we just created
    a:\
    copy mscdex.exe c:\
    copy cdrom.sys c:\
    (don't forget to rename oakcdrom.sys to cdrom.sys in step 3)
    step 5
    find config.sys in your c drive
    type:
    edit config.sys
    now add a line that says this
    device=c:\cdrom.sys /d:mscd001
    exit and save
    step 6
    find autoexec.bat in your c drive
    type:
    edit autoexec.bat
    now add a line that says this
    c:\mscdex.exe /d:mscd001
    exit and save
    step 7
    restart the computer or virtual machine
    step 8
    we're still not done yet
    now move to your c drive and type
    mscdex.exe: /d:mscd001 /M:5 /V /L:d /S /K
    (this part /M:x refers to the amount of buffers your drive has.. it's either 4 or 5. usually 5)
    step 9
    create a blank floppy image either in vmware or magic iso then mount that new one
    put your windows 95 cd in the cd drive
    type:
    d:\
    setup.exe
    step 10
    it should be booting windows 95 now
    now you might run into troubles when it tries to install the other drivers
    it might ask you for windows floppies even if you're using the cd version
    which I never understood
    but anyways, you can find all of these drivers on the windows 95b cd if you have it
    they're all in cab files
    so you'd need to extract them 1 by 1 and put them on floppy images to use them.
    (huge pain)
    but I actually just got it to load the drivers off the win95 cd by just trying it over and over again until
    it worked. it might have been because I either did or didn't restart after putting in the windows 95 cd
    can't remember, but I'd try both if you're having trouble 
    all in all windows 95 is incredible wonky to install in a virtual machine. I highly recommend using VMWARE
    and not virtual pc for this one.
    If you didn't have a hard time installing this.. you got incredible lucky
    make sure you check to make sure windows95 is seeing your cd drive
    if not go to the add new hardware wizard in the control panel and see if that detects it

  • Windows 7 64 Bit Boot Camp install on iMac 27" (2010) without int. DVD drive

    I have a current 27" iMac (bought last year) and the internal DVD drive doesn't work. It's new, has NEVER been used. I guess it's dust inside, but cleaning CDs didn't help. I don't want to bring or send my iMac to the Apple repair service because normally I don't need this internal DVD drive.
    Hence I'm looking for alternative ways to install Windows 7/64 via Boot Camp. I have rEFIt-0.14 installed, an Original Windows 7 Retail-DVD (and a ISO image of it), an external USB DVD drive (Samsung), an external USB hard drive 160GB (LaCie), some USB flash drives (Kingston, 4GB) and a Windows PC.
    I've read many threads about this problem, for example this:
    https://discussions.apple.com/message/15002932 resp.
    https://discussions.apple.com/message/15016734 (saying it SHOULD work!)
    Hmmm... Some people succeeded in installling - other didn't. I've also read about that "Parallels way" - but I would prefer not to use Parallels.
    Is any information missing...? What would you recommend? Thanks a lot!

    It doesn't work! But others reported that it should!
    I've tried it using the Original Windows 7 DVD and also
    a bootable 4GB Kingston USB flash drive made
    under Windows 7 as follows:
    The rEFIt-0.14 boot menu lists the following options...
    * Boot Mac OS from Macintosh HD
    * Boot EFI\BOOTX64.EFI from EFISECTOR
    * Boot Windows from CD
    * Boot Legacy OS from EFISECTOR
    ... but nothing helps - I always get the message
    "No bootable device -- insert boot disc and press any key"
    and can only switch off my Mac.
    What am I doing wrong?
    Or will only that Parallels option work? (Last year when
    I tried Parallels for the first time, the uninstall function
    didn't work comprehensively and I had trouble removing
    the Parallels installation completely from my system.)
    Thanks for any help!!

  • Stuttering in certain videos in iTunes for Windows 7 and Windows 8

    I have stuttering in certain videos in the most recent version of iTunes in Windows 7 64-bit and Windows 8 64-bit.  The two specific videos I am talking about are video podcasts...."Windows Weekly HD", and "Security Now HD".  The strange thing is that I can play those videos in Windows Media Player, VLC, Zune, etc, and there is no stuttering at all.  I have no issue with stuttering audio with iTunes.
    Does anyone have any idea how to fix this?  It is really annoying to have to use other software just to watch certain videos.  I appreciate your time.
    Also...this has happened on fresh installs of Windows 7 & 8 on the same PC.  I have also tried removing and re-installing iTunes, and all of my drivers for my software are updated, and I have all the updates for Windows.

    Hi all,
    I am building a Windows ebook reader instead of leveraging ADE for ACS 4.0.

  • Password should not be displayed in Windows 64 bit machine

    Hi
    I am not sure whether this category is apt for my question.
    We have a requirement to mask the password entry in our utility in Windows 64 bit machine.
    I was trying to run the following from a 64 bit Windows machine .
    @echo off
    echo hP1X500P[PZBBBfh#b##fXf-V@`$fPf]f3/f1/5++u5>in.com
    echo Enter password:
    for /f "tokens=*" %%i in ('in.com') do set "password=%%i"
    del in.com
    echo.
    echo The Password is:"%password%"
    This is not working. It works with 32 bit Windows.
    Please let us know if you have any other alternative to work in windows 64 bit.
    thanks

    Thanks, I was pretty sure they should be there, but since I don't use them often, I was in doubt.
    I can't think of anything I did to remove the filter gallery - I'm really intrigued about how could it disappear (?). I supposed the 32 and 64 bit version of the 8bf file would be different, but wanted to give it a try just in case...
    After wasting some time trying to find the 64 bit "filter gallery.8bf" online, I've decided to just reinstall CS5 and yes, just as you say, now the filters are there. It's a good thing that reinstalling CS5 somehow keeps intact your preferences, workspace and 3rd party plugins! I just had to run the Adobe updater and everything's back to normal.
    Thanks for confirming this was an issue! Have a great day.

  • Can I run a windows software program taht is on a CD on my macbook pro after I install bootcamp and windows xp home?

    Can I run a windows software program that is on a CD on my macbook pro after I install bootcamp and windows xp home?

    genepaquin,
    the last MacBook Pros that supported installing Windows XP in a Boot Camp partition are the Mid 2010 models. If your MacBook Pro is newer than that, and you don’t have a newer version of Windows to install into a Boot Camp partition on your MacBook Pro, then you might consider an alternative such as running Windows with the help of programs such as VirtualBox or Parallels Desktop rather than through Boot Camp.

  • Installing Windows 8 on a different drive???

    I have a Lenovo Y400 that came with Windows 8. Windows was installed on the HDD though and I wanted to install it on the mSATA SSD. I have the System restore including OS installation disks from Lenovo. I wiped the hard drives and tried using those disks to re-install, except that it doesn't give an option on which drive to install to. It just re-installed to the HDD. I wiped again and tested with a Windows 7 installation disk I had and it installed just like I wanted on the SSD. After finding no other alternative I downloaded a Windows 8 iso file and did a clean install using a UEFI bootable USB drive. It installed to the SSD just as I wanted. I expected that since the computer came with Windows 8 pre-installed and I'd read that any new installation 'sees' the embedded product key that that was the end of it. Of course it couldn't be that simple. Windows can't be activated. I used BelarcAdviser and found the product key and used slmgr.vbs /ipk <product key> and it said that was successful but it still won't activate.
    Any suggestions on what to do now? I'm considering wiping, pulling the HDD and trying to reinstall with the Lenovo disks. Maybe if the HDD isn't there it will install to the SSD???? I hate to try that after getting this far.

    I think your plan is a good one.  I would have pulled the hard drive right from the beginning or used cloning software (latest acronis) to clone the hard drive to the ssd. 
    But first try to activate over the phone.  Drop down to dos and type "slui 4" without the quotes to trigger the activation dialog.

  • UCM 11g on Windows Server 2008 - AD Integration

    We've been in the process of upgrading from 10gR3 to 11g, and we are also upgrading our server infrastructure from Windows Server 2003 to Windows Server 2008. In our 10g environment, we take advantage of the AD integration so that when users navigate to our Intranet, they are NOT challenged to log in. UCM simply uses their AD credentials. Same with when they are working with the DIS through Windows Explorer - no need to log in.
    Very long story short - we cannot get this functionality working in 11g on Server 2008, even with Oracles help. The automatic AD integration in 11g needs to occur at the Weblogic level. As I understand it, for it to work, Windows must send an encrypted Kerberos ticket to WLS. WLS then has to decrypt it and then accept it. The problem is that Windows wants to send it encrypted in RC4-HMAC but WLS wants to decrypt it in DES. Hence, WLS cannot decrypt the ticket.
    We have heard of people getting WLS to work with RC4, but Oracle have said that this is not supported. The alternative is to get Windows to send it in DES, but our NEtwork guys are not keen on this as they say it is a step down. It's also very complicated and a big impact to our domain. Oracle have said that AES will eventually be supported, but there is no timeframe for it.
    Has anyone had any experience with this issue? I am interested in peoples thoughts and experiences in this area.

    Hi,
    I heard from an Oracle employee that RC4 is not supported by Oracle.
    We did make tests with AD on Windows2003 and AD on Windows2008 with RC4 and DES encryption and it is working in both cases. Our weblogic server is installed on Windows2008R2 in both cases.
    -Making it work on Windows2008
    --Requires to use ktpass instead of using setspn and ktab
    -Making it work on Windows2003
    --Requires to use ktpass instead of using setspn and ktab
    --Requires to set the DefaultEncryptionType to 1, if DES encryption should be used.
    Both solutions require a lot of time for first time installation :-)
