  • debugging a resource leak in a printer driver

    - by MK
    I'm trying to debug a memory leak in a printer driver. I'm pretty sure it's a resource leak, not just a plain memory leak because analyzing heap with !heap -s in windbg doesn't show any increase. How do I monitor other kinds of objects with windbg? Number of GDI objects and open handles is not growing either, so what could it be?

  • Graphics driver for ubuntu on dell latitude XT

    - by marc.riera
    Hi, we have a laptop (dell latitude xt) on our company, and we would like to install ubuntu on it. windows 7 works fine out of the box, so the hardware is fine. since this laptop has a touchscreen we just installed ubuntu 10.10 netbook edition 32x. But, we do not manage to enable the touchscreen, neither the vga graphic drivers. this is the output from lspci, if somebody cares. 00:00.0 Host bridge: ATI Technologies Inc Radeon Xpress 7930 Host Bridge 00:01.0 PCI bridge: ATI Technologies Inc RS7932 PCI Bridge 00:04.0 PCI bridge: ATI Technologies Inc Device 7934 00:06.0 PCI bridge: ATI Technologies Inc RS7936 PCI Bridge 00:07.0 PCI bridge: ATI Technologies Inc Device 7937 00:13.0 USB Controller: ATI Technologies Inc SB600 USB (OHCI0) 00:13.1 USB Controller: ATI Technologies Inc SB600 USB (OHCI1) 00:13.2 USB Controller: ATI Technologies Inc SB600 USB (OHCI2) 00:13.3 USB Controller: ATI Technologies Inc SB600 USB (OHCI3) 00:13.4 USB Controller: ATI Technologies Inc SB600 USB (OHCI4) 00:13.5 USB Controller: ATI Technologies Inc SB600 USB Controller (EHCI) 00:14.0 SMBus: ATI Technologies Inc SBx00 SMBus Controller (rev 14) 00:14.1 IDE interface: ATI Technologies Inc SB600 IDE 00:14.2 Audio device: ATI Technologies Inc SBx00 Azalia (Intel HDA) 00:14.3 ISA bridge: ATI Technologies Inc SB600 PCI to LPC Bridge 00:14.4 PCI bridge: ATI Technologies Inc SBx00 PCI to PCI Bridge 01:05.0 VGA compatible controller: ATI Technologies Inc Radeon Xpress 1250 03:01.0 CardBus bridge: Texas Instruments PCIxx12 Cardbus Controller 03:01.1 FireWire (IEEE 1394): Texas Instruments PCIxx12 OHCI Compliant IEEE 1394 Host Controller 03:01.3 SD Host controller: Texas Instruments PCIxx12 SDA Standard Compliant SD Host Controller 09:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5756ME Gigabit Ethernet PCI Express 0b:00.0 Network controller: Broadcom Corporation BCM4321 802.11a/b/g/n (rev 03) I've tryied to install ati drivers 9.3 , which I downloaded and installed, unpacked and installed, builded and installed, but nothing worked.

  • SCSI driver installation trouble

    - by Vicky
    I tried to install the driver of Adaptec 39320A-Ultra 320 SCSI card in Win2003 Server R2 SP2 in a DELL PowerEdge 2950 Server. I selected the driver from the list of drivers present in windows. But it says that the device could not be started(Code 10). I tried to put the card in a system that already had the driver installed. It worked fine. So there is no problem with the hardware. I even tried downloading the driver from the manufacturer website. When I try to select install from path and install that driver, it tell no matching driver found. When I install the default driver from windows, it shows the card in SCSI group of device manager, but with an ! symbol. Also the device ID in driver details was different from that of the one present in other system where it insalled fine. Any suggessions to solve it?

  • Virtualized Development Server for simulating 3-Tier Environment

    - by chris.cyvas
    Hello, I am thinking about buying a new server based development box for development (redundantly redundant, I know ;)). Ideally, I want to run something like ESXi or Xen Hypervisor at the lowest level. Then I want to add (at least) 5 Linux VM's for the following uses: 2 Web Servers 2 Application Servers 1 Database Server I want to load balance the 2 web servers and the 2 application servers and (somewhat obviously) they need to be all networked together to simulate a production environment. Also, it used to be the case that the recommendation was to put each VM on it's own hard drive, but I'm not sure that holds water anymore. Any advice? Does anyone have any advice on how to pull this off? Gotchya's, LookOuts!, etc? Thanks!

  • Data files from development machine to iOS device

    - by StoneBreaker
    My app has created a bunch of data files as development has progressed through the simulator. Their location is obtained by this function: NSString *pathInDocumentDirectory(NSString *fileName) { NSArray *documentDirectories = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentDirectory = [documentDirectories objectAtIndex: 0]; return [documentDirectory stringByAppendingPathComponent: fileName]; } The files are now required on the device as testing of the app is moving from the simulator to actual devices. How do I transfer the data files from my current working environment to the devices?

  • Unlock device, display a text, then lock again

    - by Waza_Be
    For the need of my application, I need to display a message on the screen even if the lockscreen is enabled, then wait 3 seconds, than I have to lock again the phone as I don't want it to make unwanted phone calls in your pockets. First part is easy: if (PreferenceManager.getDefaultSharedPreferences( getBaseContext()).getBoolean("wake", false)) { KeyguardManager kgm = (KeyguardManager) getSystemService(Context.KEYGUARD_SERVICE); boolean isKeyguardUp = kgm.inKeyguardRestrictedInputMode(); WakeLocker.acquire(ProtoBenService.this); Intent myIntent = new Intent(ProtoBenService.this,LockActivity.class); myIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); if (isKeyguardUp) { ProtoBenService.this.startActivity(myIntent); } else Toast.makeText(ProtoBenService.this.getBaseContext(), intention, Toast.LENGTH_LONG).show(); WakeLocker.release(); } With this class: public abstract class WakeLocker { private static PowerManager.WakeLock wakeLock; public static void acquire(Context ctx) { if (wakeLock != null) wakeLock.release(); PowerManager pm = (PowerManager) ctx.getSystemService(Context.POWER_SERVICE); wakeLock = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK | PowerManager.ACQUIRE_CAUSES_WAKEUP | PowerManager.ON_AFTER_RELEASE, "CobeIm"); wakeLock.acquire(); } public static void release() { if (wakeLock != null) wakeLock.release(); wakeLock = null; } } And the Activity: public class LockActivity extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); Window window = getWindow(); window.addFlags(WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD); window.addFlags(WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON); window.addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON); TextView tv = new TextView(this); tv.setText("This is working!"); tv.setTextSize(45); setContentView(tv); Runnable mRunnable; Handler mHandler = new Handler(); mRunnable = new Runnable() { @Override public void run() { LockActivity.this.finish(); } }; mHandler.postDelayed(mRunnable, 3 * 1000); } } So, this is nice, the phone can display my text! The only problem comes when I want to lock again the phone, it seems that locking the phone is protected by the system... Programmatically turning off the screen and locking the phone how to lock the android programatically I think that my users won't understand the Device Admin and won't be able to activate it. Is there any workaround to lock the screen without the Device Admin stuff?

  • USB modeswitch to mass storage device

    - by Andrew
    I'm trying to install a Sierra AirCard 320U (branded as "Telstra USB 4G") into a VirtualBox Windows XP machine, on an Ubuntu 10.10 host. usb_modeswitch offers me a way to disable the "mass storage device" option, but I can't see a way to permanently re-enable it so it's usable by VirtualBox (device filters briefly detect it but then it disappears again). lsusb shows the device as: 0f3d:68aa Airprime, Incorporated When I first insert the device, it shows as 1199:0fff Sierra Wireless, Inc. Is there any way to re-enable the storage device so VirtualBox can see it?

  • What happened to the Journal of Game Development?

    - by Ricket
    The lengthy mission statement from its website states: The lack of game-specific research has prevented many in the academic community from embracing game development as a serious field of study. The Journal of Game Development (JOGD), however, provides a much-needed, peer-reviewed, medium of communication and the raison d'etre for serious academic research focused solely on game-related issues. The JOGD provides the vehicle for disseminating research and findings indigenous to the game development industry. It is an outlet for peer-reviewed research that will help validate the work and garner acceptance for the study of game development by the academic community. JOGD will serve both the game development industry and academic community by presenting leading-edge, original research, and theoretical underpinnings that detail the most recent findings in related academic disciplines, hardware, software, and technology that will directly affect the way games are conceived, developed, produced, and delivered. The Journal of Game Development was established in 2003. It's hard to find any information about the issues but at four issues per year, I estimate the last issue was distributed sometime in 2005 or 2006. It had a good editorial board of college professors and a founding editor from Ubisoft. The list of articles looks good. The price was reasonable. So what happened to it? Its website recently went down but you can see the last Archive.org version. The editor-in-chief is a professor at my school so I intend to ask him in person in a week or two, but I thought I'd see what you might be able to dig up about it first. Of course I will be sure to add an answer with his official word on the matter at that time.

  • How do I install the NVIDIA driver for a GeForce 6200?

    - by 2d4skt
    I have been recently trying to find a solution for this on the web but did not find something useful or accurate for Ubuntu 11.10. I also consulted the NVIDIA help, but things there did not work for me. I installed the additional drivers from system settings but they are not fully compatible with my GeForce 6200. First I tried finding how to stop the X server. I succeeded, but another problem was the nouveau kernel. This is really frustrating. Can anybody tell me an accurate and authentic way to install NVIDIA drivers?

  • External device/USB support in android API level 10 [migrated]

    - by chandan
    I am an android UI developer and having problem with issue with USB and external storage device support on android. What I want to have is on plug-in USB/SD card, the storage items in the devices directly show up on screen. For example the modern Operating systems have this feature that we plug in our device and it just automatically shows the contents of the device on new window. I am implementing my UI on android API level 10 and my device is IMX reference kit which has android 2.3.4 installed. I would be grateful if anyone could give specif suggestion or guideline. I already tried with external_storage.java class. but it only says that the APK is installed successfully. But no action launches on plug-in external device.

  • custom MSSQL driver

    - by hoodoos
    I had a crazy thought about writing my own MSSQL driver to make it work something like non-blocking http client, so it won't be thread thirsty and could handle lots of db queries within one thread. I tried to look over google for some guidelines about implementing MSSQL client protocol, but found none really, where do those guys get information about it when they write own implementations for PHP or python? I need a really low level to be documented so I can implement all phases of working with a connection through sockets. And would be really nice to have a an example in c# langauge. :)

  • CUDA driver installation on a laptop with nVidia NVS140M card

    - by stanigator
    I'm trying to first figure out if my computer contains a CUDA-enabled card. It has an nVidia NVS 140M card, but I can't seem to figure out if it is the 128 MB version or 256 MB version. On the laptop purchase receipt, I found out that I ordered the 128 MB version, but the control panel description of the card said otherwise as shown below: When I ran the CUDA driver from nVidia's site, it cannot find a hardware compatible with CUDA (even though the product series is CUDA-enabled, the card does not have 256 MB minimum of memory to do so). What would be your recommendations in this case with trying to use CUDA on this computer (I'm not sure if nothing can be done at this point)? Thanks in advance.
