Open handle to filter driver from user mode application

Hi,
Is there an option for  usermode application to open handle to filter driver and send it IOCTLs?
thanks,
Shosho 

Well if you are writing the filter driver, there are approaches.  For instance you can open the device it is filtering, but have unique IOCTL's for the filter to handle, or you can create a control device(s) to open, once open the filter can receive
IOCTL's that are used to manage the filtered path.

  • Open a BEx Analyzer Workbook from a Web Application Template

    Hello All,
    I want to open a BEx Analyzer Workbook from a Web Application Template.
    My vision is, that I have got a Button in my Web Application Template and when clicking on
    it a Web Analyzer Workbook opens. The Analysis Item in the template and the Grid in the workbook are based on the same DataProvider. So you can open the report in web or in excel, but the people shouldn't open Excel separately when they use the web frontend.
    I only found an export function, but this doesn't open a workbook. I couldn´t find a good solution here as well...
    Best regards

    I have scanned a document, how do I save to a specific folder on an external drive from the Preview application?

    There is no 'Save as' in Lion.  If it's a new document then select File -> Save will bring up a standard 'Save' dialog box which will allow you to specify the location.  Otherwise select File -> Duplicate and then save the duplicate.

  • How to Back Up a Hard Drive from Recovery Mode when Disk Can't Boot

    I have a mid-2009 MBP that is experiencing problems booting. I was trying to repair my disk because I was experiencing problems with my finder and spotlight not returning any results upon my requests. I read some support discussions that indicated it might have been because my preferences/plist files had been corrupted. I deleted the files and they regenerated but then my computer froze and so I rebooted it.
    My actual back-up for my hard drive is back in the u.s. (I'm currently doing field work in Brazil) but I have acquired another external hard drive to use for either booting or backing up my computer. I would normally just return my computer to a prevoius Time Machine backup, but I have valuable work from the last week that is not backed up I need to recover that my Time Machine does not include.
    I tried resetting my pram and starting the computer to the command line interface and doing the fsck, but neither worked; my disk could not be repaired because of an incorrect node structure, and it exited with signal 8.
    Is there a way to access migration assist or to copy my user files beyond the core to my hard drive in recovery mode or otherwise?

    Just turn off your wireless router until you can run Time Machine to backup your Mac notebook.
    Or remove the drive from the system and connect it to another Mac and copy all your files off it. But again it would be best to disable any and all Wifi systems in your house before you do that.
    Not sure but there may be a way to turn off the Wipe command and or it is only issued once. Never had to use it so I'm uncertain on how it actually works.

  • Project started in Terminal session stops responding while saving to maped network drive from user wokstation.

    Project is installed on Windows 2012R2 and is used as RemoteApp.
    If rdp file is configured to connect all or any user local drives Project hangs just after pressing "Save" button. If i forbid local drive mapping in collection settings or just rdp file - everythig works. The problem is that we need to map local
    drives because we use file associations.
    I've seen a lot of same questions about different Office applications hanging while saving to \\tsclient without solutions :(

    vden,
    Thanks for the post!  Let me confirm that I understand the issue, when drive redirection is enabled and you attempt to save a file to the mapped local drive the RemoteApp application hangs? 
    If my understanding of the issue is correct, this should not happen.  Does the app, for example, Project ever recover or does it always remain hung?

  • Open URL in Web Browser from a Java Application

    Hi,
    I have an HTML document that I want to load in a browser window by clicking on a button in my java GUI application.
    Any suggestions?
    Thanks.

    You can use the Process class to start the web browser with the proper command line arguments (depends on the web browser though). Or on windows, you can have your program create a batch file with the code start url (where [url] is your url), and this will open the default web browser when run (again you must run it with a Process).

  • Help needed: Handling web service requests from a J2SE application

    I want to write an J2SE application that is able to receive and parse web service requests. I want the application to, when started, start listen for incoming requests on a specific port.
    So far, I have embedded Apache Tomcat and Apache Axis in my application so that they parse the incoming requests and pass them on to my application logic.
    This seems like a very cumbersome way of doing it. I have included an almost full J2EE server in my application just to be able to parse web service requests.
    Is there an easier way? What technologies could I use? Any help would be greatly appreciated.

    Thanks for the help!
    It seems awfully complex though. Couldn't one just
    listen to incoming requests on a socket and use some
    good tool to parse them?
    Of course you could. One of the projects in that list is a 1 class java file. It could listen for requests, then you could parse the posted SOAP messages using JAXP and pass the requests on to your application. This will require a good understanding of SOAP however, and it may end up taking more time than simply using the JWSDP with a slightly beefier server.
    Given that there is only a handful carefully
    specified requests that the application needs to be
    able to respond to it seems overkill to include a
    full servlet enabled server...

  • Open a Windows help file from a Java application

    Help!!! Final project due Wednesday. Our project was to re-create the Windows 2k calculator, which we pretty well did, with the exception of accessing the help file. I think I am close but not sure how to deal with the compiled HTML files that Windows uses for its help utilities. The following code makes the calculator itself pop up.
    public void helpFilePopUp ()
    try
    String command = "calc";
    Process child = Runtime.getRuntime().exec(command);
    catch (IOException e)
    System.out.println("Object not found.");
    }//end of method
    Thanks in advance A.

    Maybe I didn't understand your problem correctly.
    If you just want to start the windows help with the calculator helpfile then your command should look like
    "WINHLP32.EXE c:\windows\help\calc.hlp" and not "calc".

  • User Mode Block Device Driver

    Hi,
    I want to write a block device driver in user mode so that the read and write calls from the FileSystem comes to user mode component than a regular kernel mode driver.
    why i want to do this ... because I want to pass on the data coming to another apps and the data is near real time and large. So, I can't keep the block driver in kernel mode and do transfer of data from kernel mode to user mode.
    Can this be done ... ? I have been looking at various things but nothing comes close. Any hints will be helpful.
    Thanks
    Tarrot .

    Well. The 2 user apps cannot talk directly as User APPs2 only understands block I/O requests as input so it has to have a FS over it which is ext3. User APPs1 is an application that runs over FS and writes to it like windows explorer.
    The Problem is I am not able to find a way to write a user mode block driver. Why I want this to be user mode so that I can interface to Virtual disk below which is a user mode application, i.e. User Apps2.
    I can write a kernel mode block driver there but it would not be efficient as I will have to push it from kernel mode to user mode for userapps2.
    I hope it explains....

  • Suspended User Mode Program

    I have a filter driver that communicates with a user-mode program.  I try to control for system-level events, such as paging IO, but most IO calls will result in a round-trip between the filter driver and the UM program.  If the UM program crashes
    or is otherwise stopped, the filter driver notices the communication port is down and the system continues more or less as normal.  However, I noticed that when the UM program is suspended, such as when I try to create a DMP file from taskmgr or procexp,
    the system becomes unresponsive.  This makes sense, since the communication port is still technically open, and the filter driver, being none the wiser, will keep sending events through it and expecting a response.  I suspect the events time
    out, but due to the nature of some of the events, I need a fairly high timeout (I use ~30 seconds currently).  Because of the unresponsiveness of the system, the situation is pretty difficult to trouble-shoot.
    I must not have been the first to encounter this problem.  Are there some known ways to deal with this situation?  I tried to find a kernel-mode equivalent to
    CheckRemoteDebuggerPresent, which would not be a silver bullet, especially right around the time the UM program is being suspended, but might lead to eventual recovery.  I could not find an equivalent, though.

    Well this is the reason a lot of the filter driver user space code is put into a Windows service.  There is not a good way to check, there are some undocumented stuff in ZwQueryInformationProcess, but that is about all.

  • Impossible to boot MacBook Pro Retina ! impossible to start in single user mode, Openfirmware password set, but safari works!

    I have got a Macbook pro retina.
    I have done 2 partitions on the SSD drive. 1 for the OS and 1 for the user (with a kind of ln -s /Home/myself /Volume/Part2/myself
    I was watching a movie (with VLC) in full screen for a while and I wanted to escape. Impossible, and impossible to reboot.
    When I start, I have a directory with a question mark.
    I have a Open firmware passwords set (that I remember).
    I cannot reset PRAM. (I can not change the RAM amount inside the commuter as this is a retina model)
    I cannot start in verbose mode.
    I can choose a disk to boot. I see only the OS drive and not the user partition, and no 'recovery partition'. It seems that i need to do a fsck -yff on the user partition but how ?
    I can start the OS partition, and i can choose 'guess' or 'myself'. If i choose myself, I have an error message :'there is a error, the session can not start'. If I start with the guess account, I restart, and then I can browse the internet with safari (this is how I am writing this text!)
    => How can i repair the partition ? (open a terminal, boot in single user mode ...?)
    best regards.

    Actually, the recovery partition was there, but was not shown as my user partition. I have seen that reseting the PRAM and changing the ram could remove the open firemware password. So i have turn the computer on until the battery was empty. Then I boot about 20 times, and unplug the power supply after few seconds at different step of the booting pricess. At last, the screen default resolution when booting changed, I undertood that i succeeded, and I was able to enter.
    Then I boot in single user mode, removed the open firmware password, activated the root user,  and everything was fine now !

  • Interlocked operations in user-mode

    Hi, I understand there isn't a interface for interlocked operations in user-mode.
    I would appreciate any help on how to write an implementation by myself. This help should
    also include how to compile assembler files in SOLARIS , or how to inline assembler in the
    C sources themself.
    Note that the compiler is GCC
    Thanks!!!

    >
    I'm not sure I agree with this - the canonical example
    of where atomic integer operations provide the "one
    true way" is reference counting. I tend to agree with you here - indeed, for high-granularity objects even 8-byte light-weight mutex would be a significant penalty, and reference counting is indeed the natural place for interlocked
    arithmetics. The point is, you probably do not want to have reference counting for small objects -
    these days it might be cheaper to create multiple copies. Anyway, this has to do with design,
    and good design should address the issue.
    >
    Similar discussions have been taking place in other
    threads on other forums. The general feeling seems to
    be suprise that interlocked integer operations are not
    part of the solaris ABI, though the existence of
    <sys/atomic.h> shows that they are part of the kernel.
    While we are at it, even the membar APIs in
    <sys/atomic.h> have use in user mode application code
    - esp. w.r.t the double-checked locking idiom when
    implemented on a multi-processor machine. It is
    impossible, even with volatile, to ensure that double
    checked locking will work on an SMP machine without
    inserting memory barriers. Furthermore, even if it is
    true that 99.9% of the cases are handled with the
    existing threads library, that is not a sufficient
    reason to exclude a well known and widely used
    synchronization primitive from user mode. It is clear
    that users of solaris, both on sparc and intel, want a
    standardized user-mode atomic integer operations API.
    Perhaps just a user level implementation of
    <sys/atomic.h> would do.Once again, I would probably agree with the argument - provided, we are talking about single
    platform implementation. Unfortunately enough, interlocked operations aren't part of any standard,
    so there is no way to create any platform-independent solution (unless one wants to use
    concurrency-supportive languages like Ada 95).
    I'd vote for inclusion of interlocked primitives into POSIX standard - then it will become mandatory
    for the platform vendors... I doubt, however, whether Micro$oft would support this gracefully - so
    far they have screwed up everything they've ever touched... :(

  • Getting slice/volume size from kernel mode

    Hi, my driver needs to be able to get a slice/volume size in LBs.
    Until now, when I wanted to send IOCTLS in kernel mode I used the
    cdev_ioctl function.
    However I'v encountered some strange problems when using this
    function for disksuite devices. The DIOCINFO IOCTL works fine, however
    neither DKIOCGVTOC nor DKIOCGAPART worked. The rc is 0 but the buffers
    contained random garabage. Does anyone have any idea what's wrong?
    Further info:
    1.On scsi or veritas volume manager devices these IOCTLS works fine, only on
    devices controleld by the disksuite driver (md) am I encountering such problems.
    2.The OS is solaris 8.
    3.The IOCTLS work fine from user-mode for all devices types.
    4.I am using cdev_ioctl as follows:
    cdev_ioctl(hTargetDevice, /*The device dev_t*/
    ioctlCode, /*Ioctl code*/
    (intptr_t)pInputBuffer, /*The info structure*/
    FKIOCTL|FREAD, /*Kernel ioctl*/
    kcred, /*Root privileges*/
    &ioctlRval);
    Any help is appreciated.

    Hi, for other peoples information - I finally figured out the problem. It was actually a faulty RAM module which I had bought. I had upgraded from 2 to 4 gb of RAM using an approved type of RAM for my particular computer. Finally I removed one module of RAM (after doing nearly everything else under the sun including trying to reinstall the operating system and wipe the computer etc) and the computer worked fine.
