  • GDI handles in a DotNET application

    - by David Rutten
    My pure DotNET library runs as a plugin inside an unmanaged desktop application. I've been getting a steady (though low) stream of crash reports that seem to indicate a problem with GDI handles (fonts in error messages etc. revert to the system font, display of all sorts of controls break down, massive crash shortly after). My Forms have few controls, but I do a lot of GDI+ drawing in User controls. What's a good way to tell how many handles I'm using, or even leaking? Thanks, David

  • How to send REGISTER request periodically from my SIP client to Asterisk server using Asterisk Manag

    - by Prashant
    Hi, I am using Asterisk 1.4 server and I have created a desktop client using the Asterisk.NET Library. I am able to log into the AMI (as a manager) using Asterisk.Net, but I cannot find a way to send the REGISTER command using the AMI, to share my client's location information with the server. I want to know an AMI or a CLI command that can send a REGISTER request to the Asterisk Server. Thanks

  • Tomcat 7 on Ubuntu 12.04 startup issues

    - by Nico Huysamen
    I am having trouble getting tomcat 7 to start up on my new VPS. I am really scratching my head since I have done this often. So I'm thinking it might be the VPS. I just got a new VPS from CINFU. After a clean install of Ubuntu 12.04 32bit, I install openjdk-6-jdk, update JAVA_HOME to point to: /usr/lib/jvm/java-1.6.0-openjdk-i386 and JRE_HOME to: /usr/lib/jvm/java-1.6.0-openjdk-i386/jre But when I try to run: ./catalina.sh run it simply outputs: Using CATALINA_BASE: /opt/tomcat/apache-tomcat-7.0.29 Using CATALINA_HOME: /opt/tomcat/apache-tomcat-7.0.29 Using CATALINA_TMPDIR: /opt/tomcat/apache-tomcat-7.0.29/temp Using JRE_HOME: /usr/lib/jvm/java-1.6.0-openjdk-i386 Using CLASSPATH: /opt/tomcat/apache-tomcat-7.0.29/bin/bootstrap.jar:/opt/tomcat/apache-tomcat-7.0.29/bin/tomcat-juli.jar and stops. It just hangs there doing nothing. If I run ./startup.sh && tail -f ../logs/catalina.out it gets to: Aug 24, 2012 8:38:36 PM org.apache.coyote.AbstractProtocol init INFO: Initializing ProtocolHandler ["http-bio-8080"] Aug 24, 2012 8:38:36 PM org.apache.coyote.AbstractProtocol init INFO: Initializing ProtocolHandler ["ajp-bio-8009"] Aug 24, 2012 8:38:36 PM org.apache.catalina.startup.Catalina load INFO: Initialization processed in 495 ms Aug 24, 2012 8:38:36 PM org.apache.catalina.core.StandardService startInternal INFO: Starting service Catalina Aug 24, 2012 8:38:36 PM org.apache.catalina.core.StandardEngine startInternal INFO: Starting Servlet Engine: Apache Tomcat/7.0.29 but I am unable to access anything. The request just hangs. I have also tried a few other things like explicitly exporting the paths etc in catalina.sh, and running ./startup.sh rather than catalina.sh, but the furthest I have gotten is that it finishes deploying all the WARs (the default ones that comes with tomcat like the host-manager etc), but then it hangs: Aug 24, 2012 8:47:30 PM org.apache.coyote.AbstractProtocol init INFO: Initializing ProtocolHandler ["http-bio-8080"] and does nothing. Anyone have any pointers that might help? As I said, I must really be missing something stupid since this has worked on all other VPSs that we have. UPDATE I figured out that the problem is actually the fact that they use OpnVZ virtualization and that there are known compatibility problems with Java.

  • Parallel programming patterns for C#?

    - by VoidDweller
    With Intel's launch of a Hexa-Core processor for the desktop, it looks like we can no longer wait for Microsoft to make many-core programming "easy". I just order a copy of Joe Duffy's book Concurrent Programming on Windows. This looks like a great place to start, though, I am hoping some of you who have been targeting multi/many core systems would point me to some good resources that have or would have helped on your projects?

  • Can a Winforms/WPF app act as HTTP server?

    - by user46703
    Hi, I have a desktop written with Winforms. Now I have requests that people want to access the data from other machines. First I thought about a regular Client/Server app but now I think best would be if the app could act as HTTP server and send HTML to connected browsers. Does anybody know if there is a library available to add HTTP server functionality to an app? Ideally it would be able to serve ASP.NET content.

  • Difference between Java SE/EE/ME?

    - by Richard Knop
    Which one should I install when I want to start learning Java? I going to start with some basics so I will create simple programs that create files, directories, edit XML files and so on, nothing too complex for now. I guess Java SE (Standard Edition) is the one I should install on my Windows 7 desktop? I already have Komodo IDE which I will use to write Java code.

  • Lightweight Linux distro that includes developer tools? (or, the most BSD-like Linux)

    - by RevAaron
    I cut my teeth on Minix and Slackware 1.1, but I've been in the OS X Wilderness for the last few years. I'm trying to standardize on a Linux distribution for personal and work-related use on less powerful laptops and under virtualization. So far, NetBSD and OpenBSD are the best fit for my purposes- but after plenty of frustration I've come to the conclusion that I need to stick with Linux to get the hardware and software support that comes with it. What I like about NetBSD/OpenBSD that I'd like to keep: X, but no default KDE, GNOME or XFCE! A sensible /etc and dot file setup- startx calls xinit, xinit looks for ~/.xinitrc; nothing more complicated than that is needed. Command line tools and file-based configuration: I shouldn't need a GUI to connect to a WAP. Decent selection of binary packages; building from source is OK, but nothing source-only like Gentoo. pkg_add (BSD) and apt-get both have treated me well in the past. Modest RAM and HDD requirements: boot + X + awesome+ two xterms takes up 80 MB on OpenBSD and 240 MB on Debian 5 and Crunchbang In my experience, most "lightweight" and Live CDs focus on a nice desktop environment crammed into a CD or USB stick; once you add build-essentials you end up with something just about as bloated as Ubuntu or Debian full install. Crunchbang is a great example. Thanks in advance for all suggestions!

  • VMware vSphere Hypervisor 5 with Intel SPL 5000 in Raid 0 no boot from DVD?

    - by Richard
    I hope this is the correct StackExchange, since I am only using StackOverflow for Web development, but need some help with my server configuration. I would like to install VMware vSphere Hypervisor 5 on my server here at home and run a view machines on it such as Windows Server 2008 and Red Hat. I used to have either OpenSuse or Windows Server 2008 installed but I would like to get into VMWare Hypervisor. My hardware configuration: - Intel S5000PSL with bios version S5000.86B.10.60.0091 build date 10/09/2008 as of read out of bios - E5420 @ 2.5GHz Intel Xeon CPU The Intel Virtualization Technology is enabled in the BIOS - DVD DH20A4P DVD Writer - 8GB ECC Ram I have configured a RAID 0 on my 2 WD 2TB SATA drives I have burned the Hypervisor 5 on an empty DVD and it is bootable, I tested it on my client PC. The main problem here is basically, that I cannot boot the DVD on my server. I have set the Boot Option to the DVD drive. I have booted from the BIOS straight in the DVD drive and it does not work. I do not see any error messages. The only thing I see are the PXE error messages when it tries booting from the network and other devices, obviously without any result. Does anybody know why I cannot boot the DVD? What could cause the problem? I have sucessfully installed Windows Server 2008 via original DVD about 1 year ago, so the DVD drive can read and does work. The DVD drive is available in the BIOS and I have checked all cables and none of them is loose in any way. I even see the light flashing but it does not want to boot from the DVD. I am looking forward to suggestions and things that I should check. Thank you very much

    I am making a desktop application to connect with an embedded device. I was going to use Windows but due to lack of proper examples and documentation I decided to go with Linux bluez development. Can someone suggest a good resource to go about programming for bluez. I found a MIT documentation but that was about it.

  • "SSH server" in Windows?

    - by Benjamin Oakes
    I have some command-line commands to execute on a Windows machine. The programs I need to run are only available on Windows. Is there a way to easily to do something like I would do with SSH? Example of what I mean: ssh [email protected] "remote command to execute" ...or do I have to Remote Desktop just to do this? (I'd like to run the commands programmatically from another computer rather than running them by hand.)

  • Creating mdraid device on top of other existing mdraid devices

    - by Dmitriusan
    I'm considering creating something like "hierarchical raid" and wondering whether it is possible using pure mdraid. Moreover, I'm going to boot from this device. I'm using Ubuntu Server 12.04 LTS with Grub2 bootloader. Motivation behind doing that is: I have 4 x 1tb 7200rpm disks. Two are newer and faster (up to 200mb/sec) and other two are slower (up to 140mb/sec). I want to create RAID-0 device from them. When creating such RAID-0 directly from 4 hard disks, I get summary speed up to ~480mb/sec. That is roughly 4*120mb/sec, so RAID-0 works with speed of the slowest device. I have an idea to create a separate RAID-0 md0 device from 500gb partitions of slower hard disks. Theoretically, this md0 device will have speed 2*140=240~280mb/sec. After that, I'm going to add this md0 device to RAID-0 with faster disks, finishing with up to 3*200=600mb/sec. Stripe-width for this raid will be 2x times bigger than for underlying raid with slow disks. Questions are: is it possible or I'm missing something? will that work as expected? can I boot from such consolidated raid device? any better ideas? any pitfalls? I don't want to use fakeraid for consolidating slow disks for multiple reasons (portability, ability to customize parameters and so on). PS Speed is needed for home virtualization server and just for experience/fun. Reliability is provided via regular automatic backups to a separate device. PPS I considered also using different stripe-width for hard disks with different speed in single raid, but mdraid does not seem to support that.

  • Clustering/load balancing for cluster unaware applications

    - by AaronLS
    Forgive me if I use any of these terms incorrectly. I am wondering if there is any kind of software that would allow my two "join" two computers together such that a cluster unaware application could utilize their combined computing resources? By "cluster unaware" I mean an application that isn't designed to share work across multiple services. My understanding is that clustering is enabled by the specific application by it's architecture, such that messaging with multiple instances of the application coordinate the sharing of work. Instead I am looking for something that enables clustering at the OS or virtualization level, so that any application could essentially be clustered. Failing that, I am also wondering about the following scenario: We have 3 different applications we will call A, B, and C. We have 2 single core computers. At any given time lets say that any combination of those applications will be CPU intensive. In cases where only 2 of those apps are very active, have one of them moved over to a different server. In a nutshell, some sort of dynamic automatic shuffling of the application's load. I have heard of virtual machines that can be migrated across physical machines while live, but I am wondering if this can be done automatically in response to an application's or VM's CPU activity?

  • I need help with this ogre dependent header (Qgears)

    - by commodore
    I'm 2 errors away from compiling Qgears. (Hacked Version of the Final Fantasy VII Engine) I've messed with the preprocessors to load the actual location of the ogre header files. Here are the errors: ||=== qgears, Debug ===| /home/cj/Desktop/qgears/trunk/project/linux/src/core/TextManager.h|48|error: invalid use of ‘::’| /home/cj/Desktop/qgears/trunk/project/linux/src/core/TextManager.h|48|error: expected ‘;’ before ‘m_LanguageRoot’| ||=== Build finished: 2 errors, 0 warnings ===| Here's the header file: // $Id$ #ifndef TEXT_MANAGER_h #define TEXT_MANAGER_h #include <OGRE/OgreString.h> #include <OGRE/OgreUTFString.h> #include <map> struct TextData { TextData(): text(""), width(0), height(0) { } Ogre::String name; Ogre::UTFString text; int width; int height; }; typedef std::vector<TextData> TextDataVector; class TextManager { public: TextManager(void); virtual ~TextManager(void); void SetLanguageRoot(const Ogre::String& root); void LoadTexts(const Ogre::String& file_name); void UnloadTexts(const Ogre::String& file_name); const TextData GetText(const Ogre::String& name); private: struct TextBlock { Ogre::String block_name; std::vector<TextData> text; } Ogre::String m_LanguageRoot; // Line #48 std::list<TextBlock> m_Texts; }; extern TextManager* g_TextManager; #endif // TEXT_MANAGER_h The only header file that's in include that's not a ogre header file is "map". If it helps, I'm using the Code::Blocks IDE/GCC Compiler in GNU/Linux. (Arch) I'm not sure even if I get this header fixed, I think I'll have build errors latter, but it's worth a shot. Edit: I added the semicolon and I have one more error in the header file: error: expected unqualified-id before ‘{’ token

  • Networking problems in VMWare with wireless bridge

    - by Robert Koritnik
    Barebone data: virtualization: VMWare Workstation 6.5 (latest) Host: Windows Server 2008 x64 Guest: Windows Server 2008 x86 Host network adapter: wireless Guest network adapter 1: over Bridge VMNet (automatic) Guest network adapter 2: over Host only VMNet Problem When I surf the net within VM my internet connection just gets stalled (not dropped). It doesn't experience any timeout whatsoever, it just stops downloading/communicating. For instance: I start downloading a file with a browser (IE/FF/CR doesn't matter) and I have to pause/restart download when speed drops to 0. I could wait indefinitelly but connection won't pickup automatically. What did I miss in my network configuration? Update 1 I've tested this in various combinations. This works fine when host is connected via Ethernet. But when connected via Wifi, the connection on the guest works as previously described. It connects fine. It gets a valid IP from DHCP... Everything is cool as long as you don't start doing some intensive network traffic (ie. download a 2MB file) In this case it starts downloading and stops after a while. Speed just drops to 0B/s... Sometimes it picks up back, sometimes it doesn't. Connection still stays and works. I can ping around with no problem.
