  • Displaying and capturing c# exceptions

    - by Frank Meulenaar
    I have a c# program which throws a NullReferenceException(). When I start this on my Vista machine, it gives the familiar screen "Foo has stopped working". I can easily click on 'details' to see what went wrong. On one XP machine there's no warning at all: the program just quits, and on another XP I get the "Foo has encountered a problem..." message. Is there a way I can change this (XP's) setting? Furthermore, I would like to have this error message written to a log file, so I can see what went wrong if somebody else uses my program. Is there a way I can send the uncaught exceptions to a file?

  • Manipulating source packages from Hackage how to easy deploy to several windowsboxes?

    - by Jonke
    Recently when I have found good sources packages for ghc 6.12/6.10 on Hackage I've been forced to do some minor or major changes to the cabal files to make those packages to work under windows. Besides to fork and merge my fixes with github, what seems to be the best way/ good enough practice to take these modified builds to a couple of other windows boxes that only has a basic haskell platform installed? I should prefer if I somehow could work with the cabal-install because that is what one normally use. Should one put the modfied build dirs on a shared/networked dir and mount from the targeted windows box? Say something like this: on machine prepare cabal fetch foo cabal unpack foo cd foo edit .cabal and .hs cabal configure cabal build On machine useanddevelopnormal cd machinepreparemount cd foo cabal install

  • Running GUI application in the Windows service mode

    - by Leonid
    I'm writing a server running as a Windows service that by request invokes Firefox to generate a pdf snapshot of a webpage. I know it is a bad idea to run a GUI program in service mode, but the server nature of my program restricts from running it in the user mode. Running a user-level 'proxy' also is not an option, since there might be no interactive user logged-in on the machine with the server running. In my experiments Firefox successfully produced pdf when the service was running under a user account that was already logged-in. Obviously it didn't work in other cases: for Local System and user accounts that weren't logged-in. Under LocalSystem with 'Allow service to interact with desktop' option enabled I could see the Firefox started that reports that it's unable to find a printer. Since it wouldn't be practical to require an opened user session for the pdf server to run, is there any workaround for this except running the whole thing from a virtual machine?

  • Writing a simple batch file to setup a variable?

    - by Sam
    I want to write a simple batch file where i want to setup a environment variable based on the machine architecture. It is as below: set ARCH=%PROCESSOR_ARCHITECTURE% echo %ARCH% if %ARCH%==x86 ( set JAVA_ROOT=C:\Progra~1\Java\j2re1.4.2_13 ) else ( set JAVA_ROOT=C:\Progra~2\Java\j2re1.4.2_13 ) echo JAVA_ROOT is %JAVA_ROOT% On 64-bit machine where the architecture is 'AMD64' the JAVA_ROOT will be displayed as 'C:\Progra~2\Java\j2re1.4.2_13' at the echo statement. But when i run an application that uses this file, the first value of JAVA_ROOT would be picked up 'C:\Progra~1\Java\j2re1.4.2_13'. I don't have any idea why it goes in the 'if' part even though i am running this on 64-bit Windows7. When i echoed the

  • Install Ubuntu in UEFI mode (unable to boot from USB)

    - by Adele
    I recently bought a Dell Inspiron 15R SE with Windows 8 (64 bit) pre-installed (UEFI supported). I want to install Ubuntu in dual boot with Windows 8. I tried to follow all instruction here : https://help.ubuntu.com/community/UEFI And here : Installing Ubuntu on a Pre-Installed Windows 8 (64-bit) System (UEFI Supported) So, I set Secure Boot to "off" into BIOS and I disable Fast Startup as described here : http://www.eightforums.com/tutorials/6320-fast-startup-turn-off-windows-8-a.html I created a bootable USB key for Ubuntu (Ubuntu 13.10 64bits international Edition) with Unetbootin. The problem is I am unable to boot from the USB key. The computer tries to boot into infinite loop. I also tried to boot from USB with "Legacy Boot" option instead of UEFI. In this case, the computer says there are no bootable devices. Of course, I tried to boot from my USB key on an other computer having normal BIOS and it works perfectly. Have you ideas about what I need to do to be able to boot from USB ? Thanks in advance for your help, Adele

  • Visual studio deployment project error when writing to registry

    - by Rekreativc
    Hello I have a setup for an application that was recently converted to be a framework 4.0 project (don't know if it's relevant). The setup has to write to registry (Local Machine) and until now this has always worked perfectly, however now it fails to write to registry on a clean machine (running Windows 7, 64 bit). The setup does not fail, does not show a warning of any kind, however it does not write to the registry (I even set AlwaysCreate property to true on every key, just in case) which of course causes the application to terminate on startup. What could be the cause of this? I have never encountered such an error before. Edit: I have tried running the installer as administrator, didn't change anything.

  • Problem with testing a Windows service

    - by prateeksaluja20
    I want to make a Windows service that will access my database. My database is SQL Server 2005. Actually I am working on a website and my database is inside our server. I need to access my database every second and update the records. For that purpose I need to make a Windows service that will install into our server and perform the task. I have been accessing the database from my local machine and then running the service, but problem is I'm not sure how I can test this service. I tried to install into my local machine. It installed and then I ran the service but it did not perform the task and I think service is not able to connect with the database. There is no problem in the service nor its installer. The only issue is how to test my Windows service.

  • Using VirtualBox to test drive Windows Blue

    - by Fat Bloke
    Oracle VM VirtualBox is great for trying out the latest and greatest technologies and platforms. So when Microsoft recently announced the Developer Preview for Windows Server 2012 R2 and Windows 8.1,  it was with eager anticipation that FatBloke ran to the TechNet Evaluation Center to download the isos. Once downloaded,  a new VM in VirtualBox Manager was created that used Windows 2012 (64-bit) OS type and all the defaults were selected. And on starting the VM, and pointing to the iso file to install from, the excitement rose as we saw a cool new splashscreen image: But suddenly our hopes are dashed.... It would seem that this platform requires an instruction (CMPXCHG16B) that VirtualBox doesn't offer "out-of-the-box".  Fear not, for the VirtualBox team knew that this day would finally arrive and have prepared an "in case of emergency" switch as follows: Power off the vm; At the command line type:  VBoxManage setextradata [vmname] VBoxInternal/CPUM/CMPXCHG16B 1 Start the VM and install Windows Server 2012 R2 This will be enabled by default in a future release, but geeks can't wait, hence this blog. Enjoy! -FB

  • App losing db connection

    - by DaveKub
    I'm having a weird issue with an old Delphi app losing it's database connection. Actually, I think it's losing something else that then makes the connection either drop or be unusable. The app is written in Delphi 6 and uses the Direct Oracle Access component (v4.0.7.1) to connect to an Oracle 9i database. The app runs as a service and periodically queries the db using a TOracleQuery object (qryAlarmList). The method that is called to do this looks like this: procedure TdmMain.RefreshAlarmList; begin try qryAlarmList.Execute; except on E: Exception do begin FStatus := ssError; EventLog.LogError(-1, 'TdmMain.RefreshAlarmList', 'Message: ' + E.Message); end; end; end; It had been running fine for years, until a couple of Perl scripts were added to this machine. These scripts run every 15 minutes and look for datafiles to import into the db, and then they do a some calculations and a bunch of reads/writes to/from the db. For some reason, when they are processing large amounts of data, and then the Delphi app tries to query the db, the Delphi app throws an exception at the "qryAlarmList.Execute" line in the above code listing. The exception is always: Access violation at address 00000000. read of address 00000000 HOW can something that the Perl scripts are doing cause this?? There are other Perl scripts on this machine that load data using the same modules and method calls and we didn't have problems. To make it even weirder, there are two other apps that will also suddenly lose their ability to talk to the database at the same time as the Perl stuff is running. Neither of those apps run on this machine, but both are Delphi 6 apps that use the same DOA component to connect to the same database. We have other apps that connect to the same db, written in Java or C# and they don't seem to have any problems. I've tried adding code before the '.Execute' method is called to: check the session's connection (session.CheckConnection(true); always comes back as 'ccOK'). see whether I can access a field of the qryAlarmList object to see if maybe it's become null; can access it fine. check the state of the qryAlarmList; always says it's qsIdle. Does anyone have any suggestions of something to try? This is driving me nuts! Dave

  • Problem with Authentication in sharepoint using active directory

    - by user549708
    I am currently using windows server 2008 machine. I have active directory and sharepoint setup on the machine. I have a user 'A' in the active directory and i have given the user read permissions to my site. The problem i now face is that, if i log in as user 'A' the site simply shows "error:access denied". This problem goes away if i put 'A' as a site collection administrator, however that is not what i want. I just want 'A' to be a visitor that can browse the site. I also tried granting 'read' permission to my site for 'A' but that still gives me the access denied message. Thank you for your time.

  • Dynamic WSDL Location in .NET

    - by wadetandy
    I am building a C# application that is consuming a WSDL that is hosted by a server on our network. When I use the "Add Web Reference" functionality of Visual Studio, it works just fine, saving the ip address of the machine, etc. and the SOAP calls work without any issue. We are now making this entire application portable so that it can be installed in any environment. We would like to place all of our settings in one configuration file, so my question is this: Is it possible to somehow specify the IP address of the machine that is hosting the SOAP service in my configuration file and link everything dynamically at runtime?

  • Any reccomendations for implementing a user-defined workflow in Ruby?

    - by midas06
    I'm interested in creating a system where the user can define the steps in a workflow. Is there a gem that already handles this? I thought about one of the state machine gems, but they all seem to be for pre-defined states. I've been thinking maybe i can use state machine for the individual step types... An email step could have a few states [New, Assigned, Done], and the workflow could just be lists of these stateful steps. Are there other solutions out there?

  • SQLServer using too much memory

    - by Israel Pereira Valverde
    I have installed on my desktop machine (with windows 7) SQLServer 2008 R2 Express. I have only one local server running (./SQLEXPRESS) but the sqlserver process is taking ALL the RAM possible. With an machine with 3GB of RAM the things starts to get slow, so I limited the maximun amount of RAM in the server, and now, constantly the SQLServer give some error messages that the memory is not enought. It's using 1GB of RAM with only one LOCAL server with 2 databases completely empty, how 1GB of RAM isn't enought ? When the process start it's using an really acceptable amount of memory (around 80MB) but it's keep increasing until it reaches the maximun defined and start to complain about having not enought memory available. In that point I have to restart the server to use it again. I have read about an hotfix to solve one of the errors I got from sqlserver: There is insufficient system memory in resource pool 'internal' to run this query But it's already installed on my sqlserver. Why it's using so much memory?

  • How to tackle an experienced C# Programmer?

    - by nandu.com
    I am a noob in c# and asp.net developing. I have spent 6 months in design and another 6 in sql and asp.net programming. I just know the basics of asp.net and C#. I was programming as per the instruction of my tech leads and all good things changed in a day. :( All my tech leads (2+ experienced) left the company complaining about salary. And instead of those, company has recruited a 5+ experienced programmer cum tech lead (who is very strict), he is expecting me to code anything he says. Previous seniors of me, would say 'use ajax for this, use query for this instead of coding' and so on. I will do it exactly. I am not experienced enough to perform it myself. Now I am in a dilemma. I want to stay in the company and learn some more, but this new tech lead is expecting me to learn everything myself (he is telling me to learn jquery, javascript menus, session and chart in .Net, and so on and do things myself without asking him anything...I mean anything) :(((( PLease suggest to me some good tips to handle him. I think all programmers world wide would have faced a similar problem atleast once in the big programming life. So please..help .. 911

  • Getting the 'external' IP address in Java

    - by Caylem
    Hi I'm not too sure how to go about getting the external IP address of the machine as a computer outside of a network would see it. My following IPAddress class only gets the local IP address of the machine. Any help would be appreciated. Thanks. public class IPAddress { private InetAddress thisIp; private String thisIpAddress; private void setIpAdd(){ try{ InetAddress thisIp = InetAddress.getLocalHost(); thisIpAddress = thisIp.getHostAddress().toString(); } catch(Exception e){} } protected String getIpAddress(){ setIpAdd(); return thisIpAddress; } }

  • Java RMI cannot connect to host from external client.

    - by Koe
    I've been using RMI in this project for a while. I've gotten the client program to connect (amongst other things) to the server when running it over my LAN, however when running it over the internet I'm running into the following exception: java.rmi.ConnectException: Connection refused to host: (private IP of host machine); nested exception is: java.net.ConnectException: Connection timed out: connect at sun.rmi.transport.tcp.TCPEndpoint.newSocket(Unknown Source) at sun.rmi.transport.tcp.TCPChannel.createConnection(Unknown Source) at sun.rmi.transport.tcp.TCPChannel.newConnection(Unknown Source) at sun.rmi.server.UnicastRef.invoke(Unknown Source) at java.rmi.server.RemoteObjectInvocationHandler.invokeRemoteMethod(Unknown Source) at java.rmi.server.RemoteObjectInvocationHandler.invoke(Unknown Source) at $Proxy1.ping(Unknown Source) at client.Launcher$PingLabel.runPing(Launcher.java:366) at client.Launcher$PingLabel.<init>(Launcher.java:353) at client.Launcher.setupContentPane(Launcher.java:112) at client.Launcher.<init>(Launcher.java:99) at client.Launcher.main(Launcher.java:59) Caused by: java.net.ConnectException: Connection timed out: connect at java.net.PlainSocketImpl.socketConnect(Native Method) at java.net.PlainSocketImpl.doConnect(Unknown Source) at java.net.PlainSocketImpl.connectToAddress(Unknown Source) at java.net.PlainSocketImpl.connect(Unknown Source) at java.net.SocksSocketImpl.connect(Unknown Source) at java.net.Socket.connect(Unknown Source) at java.net.Socket.connect(Unknown Source) at java.net.Socket.<init>(Unknown Source) at java.net.Socket.<init>(Unknown Source) at sun.rmi.transport.proxy.RMIDirectSocketFactory.createSocket(Unknown Source) at sun.rmi.transport.proxy.RMIMasterSocketFactory.createSocket(Unknown Source) ... 12 more This error is remeniscent of my early implementation of RMI and I can obtain the error verbatum if I run the client locally without the server program running as well. To me Connection Timed Out means a problem with the server's response. Here's the client initiation: public static void main(String[] args) { try { String host = "<WAN IP>"; Registry registry = LocateRegistry.getRegistry(host, 1099); Login lstub = (Login) registry.lookup("Login Server"); Information istub = (Information) registry.lookup("Game Server"); new Launcher(istub, lstub); } catch (RemoteException e) { System.err.println("Client exception: " + e.toString()); e.printStackTrace(); } catch (NotBoundException e) { System.err.println("Client exception: " + e.toString()); e.printStackTrace(); } } Interestingly enough no Remote Exception is thrown here. Here's the server initiation: public static void main(String args[]) { try { GameServer gobj = new GameServer(); Information gstub = (Information) UnicastRemoteObject.exportObject( gobj, 1099); Registry registry = LocateRegistry.createRegistry(1099); registry.bind("Game Server", gstub); LoginServer lobj = new LoginServer(gobj); Login lstub = (Login) UnicastRemoteObject.exportObject(lobj, 7099); // Bind the remote object's stub in the registry registry.bind("Login Server", lstub); System.out.println("Server ready"); } catch (Exception e) { System.err.println("Server exception: " + e.toString()); e.printStackTrace(); } } Bad practice with the catch(Exception e) I know but bear with me. Up to this stage I know it works fine over the LAN, here's where the exception occurs over the WAN and is the first place a method in the server is called: private class PingLabel extends JLabel { private static final long serialVersionUID = 1L; public PingLabel() { super(""); runPing(); } public void setText(String text) { super.setText("Ping: " + text + "ms"); } public void runPing() { try { PingThread pt = new PingThread(); gameServer.ping(); pt.setRecieved(true); setText("" + pt.getTime()); } catch (RemoteException e) { e.printStackTrace(); } } } That's a label placed on the launcher as a ping test. the method ping(), in gameserver does nothing, as in is a null method. It's worth noting also that ports 1099 and 7099 are forwarded to the server machine (which should be obvious from the stack trace). Can anyone see anyting I'm missing/doing wrong? If you need any more information just ask. EDIT: I'm practically certain the problem has nothing to do with my router settings. When disabling my port forwarding settings I get a slightly different error: Client exception: java.rmi.ConnectException: Connection refused to host: (-WAN IP NOT LOCAL IP-); but it appears both on the machine locally connected to the server and on the remote machine. In addition, I got it to work seamlessly when connecting the server straight tho the modem (cutting out the router. I can only conclude the problem is in my router's settings but can't see where (I've checked and double checked the port forwarding page). That's the only answer i can come up with.

  • Cannot boot after installing ubuntu on lenovo x120e

    - by tutysara
    I have installed ubuntu 11.10 on my x120e using amd64 alternate iso image. The installation went fine, but it is having issues while booting after a successful installation, it says - "No Operating System Found". I followed the instruction at - help.ubuntu.com/community/X120e#Installation to purge grub-efi and installed grub-pc, even then I couldn't boot into ubuntu.(got the same "No Operating System Found") This is the file from boot-repair with this setup - http://pastebin.ubuntu.com/926556/ Then I asked in #ubuntu and they suggested me to create a bios-boot partition, I was not very comfortable with the solution they had suggested but gave it a try anyhow. I re-sized my initial partition and made 4 MB free space in the beginning of the partition and had set the flag bios_grub. Re-installed ubuntu 11.10 this time using amd64 desktop iso image file. Installation went fine as before but finally this time also the system didn't boot, it gave the same - "No Operating System Found" message. In BIOS I have the settings as to use both (Legacy and UEFI) and with UEFI tried first. This is the boot-repair file from my latest setup - http://pastebin.ubuntu.com/926761 Any help/suggestions are appreciated.

  • Efficient multiple services exposed over c# .NET remoting using more channels or end points?

    - by wb
    I am using remoting over TCP for a prototype distributed server application where I want to have varying multiple services exposed from each remoting server process. In some cases I want the services running from the same process but I don't want whatever is using the service to care about that. I am wondering is it more efficient to have multiple services in the same process going over the same remoting channel distinguished by endpoint URI/URL or should I be creating new channels on different ports for each service in the same process? Using up ports isn't so much of a problem as the number of services will be low and the network and machine configuration is completely controlled. Also its not clear to me if remoting sends the URI string for every single message or just at connection time, and whether if the remoting framework is intelligent enough to reduce work if calls are made on the same machine and even the same process? Thanks in advance.

  • How do I get IE to open a file with its associated application?

    - by Wayne
    MSTest produces an XML file with a .trx extension containing test results. If I have a .trx file on a machine without Visual Studio installed, I get prompted to "Use the Web Service..." or "Select from a list...", which is expected. If I have a .trx file on my development machine and I open it, it opens in Visual Studio, which is expected. If I click a link on a web page or in an email which gets a .trx file from my build server, it ALWAYS opens the XML in IE. How do I configure IE (or IIS on the build server) to open the remote .trx file in Visual Studio, if it's installed, or prompt if it's not? UPDATE: If I rename the .trx file on the server and give it various extensions (eg. .bmp, .msi, .txt, .zip), it still opens as XML in IE, so it's clearly going by the content of the file and not the declared MIME type.

  • ZF-Autoloader not working in UnitTests on Ubuntu

    - by Sam
    i got a problem regarding Unit-testing a Zend-Framework application under Ubuntu 12.04. The project-structure is a default zend application whereas the models are defined as the following ./application ./models ./DbTable ./ProjectStatus.php (Application_Model_DbTable_ProjectStatus) ./Mappers ./ProjectStatus.php (Application_Model_Mapper_ProjectStatus) ./ProjectStatus.php (Application_Model_ProjectStatus) The Problem here is with the Zend-specific autoloading. The naming convention here appears that the folder Mappers loads all classes with _Mapper but not _Mappers. This is some internal Zend behavior which is fine so far. On my windows machine the phpunit runs without any Problems, trying to initiate all those classes. On my Ubuntu machine however with jenkins running on it, phpunit fails to find the appropriate classes giving me the following error Fatal error: Class 'Application_Model_Mapper_ProjectStatus' not found in /var/lib/jenkins/jobs/PAM/workspace/tests/application/models/Mapper/ProjectStatusTest.php on line 39 The error appears to really be that the Zend-Autoloader doesn't load from the ubuntu machine, but i can't figure out how or why this works. The question remains of why this is. I think i've double checked every point of contact with the zend autoloading stuff, but i just can't figure this out. I'll paste the - from my point of view relevant snippets - and hope someone of you has any insight to this.
