Has anyone tried installing Guest-Additions in openSUSE ?

  • XP Pro SP3: DRIVER_IRQL_NOT_LESS_OR_EQUAL on hibernate

    - by Margaret
    Hey all I'm running XP Pro SP3 on a Late 2007-era 2.2Ghz Macbook. Unfortunately, it's recently started giving me a Blue Screen of Death when I try to hibernate it. It gives me the error "DRIVER_IRQL_NOT_LESS_OR_EQUAL", and at the bottom says that it's in "hiber_atapi.sys". Most of the Googling I've done thus far turns up things referring to Windows Server 2003, which is obviously less than useful. Anyone know any way to fix this short of a full re-install?

  • Logging erros in SqlLite database from C# Windows Forms Application

    - by Ismail S
    I'm developing a win app in C# which communicates to a WCF Service. I want to log exceptions that are thrown on client to be logged in Sql Lite Database (Win app is using Sql Lite database for storing data locally). And then later it should be sent to the wcf service when required so that it can be useful for support/analysis/application improvement. I want a method which can be directly called in every catch block simply by LogHelper.Log(ex). I would like to know if anyone has done it through Enterprise library or used any good practice for such situation?

  • good documentation about "avoid catching throwable", in context of weblogic server

    - by Marcel
    hi all, i am currently refactoring an existing codebase (EJBs...) to rip out all blocks where a Throwable is catched inside of the EJB. try { ... do some business logic } catch(Throwable t){ ... log and swallow ... :-( } i want/need to convince the people around me with proper documentation that "catching throwable" is a no-go for an EJB (we have lots of discussions around this :-(( ). weblogic will handle all the "Error" conditions and maybe invalidate EJBs and put fresh(working) EJBs into the pool. catching Throwable would undermine all these security nets provided by weblogic. and catching throwable is bad practice anyway (but people here are reluctant and use the "throwable" hammer everywhere). is anyone able to point me to some online docs where this behaviour is explained (for weblogic or jboss or...). i searched via google and had a look at the weblogic docs but wasn't able to find anything, just generic java doc. any help highly appreciated cheers marcel

  • ShowWindow not working from a DLL on a 64-bit OS?

    - by Auto Roast
    I have a process that calls SetWindowsHook to catch keyboard events. In the DLL that processes the events, I conditionally call ShowWindow on the handle of the window of the process who set the hook. That code works perfectly on a 32-bit OS (XP) and as a 32-bit application on a 64-bit OS, but when compiled to 64-bit, the window is not showing. The code to make the window visible is: if (idx == passlen) { HWND h = FindWindow(NULL,windowNameToShow); ShowWindow(h,SW_SHOW); idx = 0; logger->backerase(passlen - 1); nextCharToMatch = passPointer; }

  • Tricky compiler behavior

    - by Neeraj
    Simple java code snippet. It has three classes. After compiling the code please delete A.class and then execute the code. Code still runs, why its not checking whether the byte code of A exists or not? class A { static { System.out.println("In the class A"); } public A() { } } class B { private A a = null; static { System.out.println("In the class B"); } public B() { a = new A(); } } public class ExampleLinkage { static { System.out.println("In the class A"); } public ExampleLinkage(String str) { } public static void main(String args[]) { try { System.out.println("In the main method of ExampleLinkage"); Class.forName("com.bt.rtti.B"); } catch(Exception e) { e.printStackTrace(); } } }

  • Starting/Stopping Custom PHP Chat Server Linux Service (CentOS)

    - by chad
    I have been trying all night to get this service working properly. I created this script from a template and am very new to bash coding. I wrote a fully functioning chat server in php which runs endlessly, but now want to make it a dedicated service. I want to do this so that it starts on server boot and boots back up if possible when there are any down-times with the server. The issue is that I need this thing to run in a detached screen so that I can monitor packet data or send server commands via SSH when need-be. The main problem that i'm having is that it needs to have its own PID when it starts so that I can stop/restart it when needed. I am the type who grinds on coding until I figure it out, but this is so new to me that it seems the learning curve here is very steep and frustrating. Below is my code if anybody can please help me with this one, i've gotten so tired I can't even concentrate any more :( #!/bin/sh # # chatserver # # chkconfig: 345 20 90 # description: chatServer Linux Service Daemon \ # for general server handling ### BEGIN INIT INFO # Provides: chatserver # Required-Start: $local_fs $network $named $syslog # Required-Stop: $local_fs $syslog # Default-Start: 3 4 5 # Default-Stop: 0 1 2 6 # Short-Description: This service maintains the chatServer # Description: chatServer Linux Service Daemon # for general server handling ### END INIT INFO # Source function library. . /etc/rc.d/init.d/functions exec="screen php -q /var/www/html/chatServer.php" prog="chatserver" config="/etc/sysconfig/$prog" pidfile="/var/run/chatserver.pid" [ -e /etc/sysconfig/$prog ] && . /etc/sysconfig/$prog lockfile=/var/lock/subsys/$prog start() { #$exec || exit 5 echo -n $"Starting $prog: " daemon $exec --name=$exec --pidfile=$pidfile retval=$? echo [ $retval -eq 0 ] && touch $lockfile return $retval } stop() { echo -n $"Stopping $prog: " killproc -p $pidfile rm -f $pidfile retval=$? echo [ $retval -eq 0 ] && rm -f $lockfile return $retval } restart() { stop start } reload() { restart } force_reload() { restart } rh_status() { # run checks to determine if the service is running or use generic status status $prog } rh_status_q() { rh_status >/dev/null 2>&1 } case "$1" in start) rh_status_q && exit 0 $1 ;; stop) rh_status_q || exit 0 $1 ;; restart) $1 ;; reload) rh_status_q || exit 7 $1 ;; force-reload) force_reload ;; status) rh_status ;; condrestart|try-restart) rh_status_q || exit 0 restart ;; *) echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload}" exit 2 esac exit $?

  • Windows 7 laptop fonts DPI is too big breaking certain applications

    - by rolls
    I have just installed windows 7 on a laptop and the fonts seem to be doing weird things, Ive adjusted the DPI back to 100% (was 125% by default) however certain applications (old delphi programmed ones) do not look correct still. Here is a screen shot comparing my laptop to my PC running the same software (ROCLink RTU configuration software), the PC looks fine but the laptop does not. Does anyone know where the problem may lie or what I should try next? Thanks

  • Returning errors from AMFPHP on purpose.

    - by Morieris
    When using flash remoting with amfphp, what can I write in php that will trigger the 'status' method that I set up in my Responder in Flash? Or more generally, how can I determine if the service call has failed? The ideal solution for me would be to throw some exception in php serverside, and catch that exception in flash clientside... How do other people handle server errors with flash remoting? var responder = new Responder( function() { trace("some normal execution finished successfully. this is fine."); }, function(e) { trace("how do I make this trigger when my server tells me something bad happened?"); } ); myService = new NetConnection; myService.connect("http://localhost:88/amfphp/gateway.php"); myService.call("someclass.someservice", responder);

  • web services access not being reached thru the web browser

    - by Tony
    I am trying to reference my .asmx webservices in .NET but my server is not exposed to the internet. When I put on the following address I get the message mentioned below. What's the reason for not being able to see the directory? Am I missing something in my IIS configuraction? Am I missing anything in my permissions? Just as reference I have other folders with webservices and I have the same issue. When I login to the server I am doing it with my windows user and password (I am using windows authentication). It's necessary to mention that when I put the URL I am getting a popup screen to put in my userid and password but it seems that's not able to validate since keeps asking me a couple of times. Let me know if you need more information to address this issue . http://appsvr02/Inetpub/wwwroot/DevWebApi/ Internet Explorer cannot display the webpage What you can try: It appears you are connected to the Internet, but you might want to try to reconnect to the Internet. Retype the address. Go back to the previous page. Most likely causes: •You are not connected to the Internet. •The website is encountering problems. •There might be a typing error in the address. More information This problem can be caused by a variety of issues, including: •Internet connectivity has been lost. •The website is temporarily unavailable. •The Domain Name Server (DNS) is not reachable. •The Domain Name Server (DNS) does not have a listing for the website's domain. •If this is an HTTPS (secure) address, click tools, click Internet Options, click Advanced, and check to be sure the SSL and TLS protocols are enabled under the security section. For offline users You can still view subscribed feeds and some recently viewed webpages. To view subscribed feeds 1.Click the Favorites Center button , click Feeds, and then click the feed you want to view. To view recently visited webpages (might not work on all pages) 1.Click Tools , and then click Work Offline. 2.Click the Favorites Center button , click History, and then click the page you want to view.

  • What are the best measures to protect content from being crawled?

    - by Moak
    I've been crawling a lot of websites for content recently and am surprised how no site so far was able to put up much resistance. Ideally the site I'm working on should not be able to be harvested so easily. So I was wondering what are the best methods to stop bots from harvesting your web content. Obvious solutions: Robots.txt (yea right) IP blacklists What can be done to catch bot activity? What can be done to make data extraction difficult? What can be done to give them crap data? Just looking for ideas, no right/wrong answer

  • How can I stop IIS7 from using HttpHandlers?

    - by mcintyre321
    I'm having a bit of a play around with IIS7, just trying to catch events manually in global.asax and skip the ASP pipeline entirely. To this end, I've set <httpHandlers> <clear/> </httpHandlers> <httpModules> <clear/> </httpModules> but when I call the server I get a YSOD [HttpException]: No http handler was found for request type 'GET' at System.Web.HttpApplication.MapHttpHandler(HttpContext context, String requestType, VirtualPath path, String pathTranslated, Boolean useAppConfig) at System.Web.HttpApplication.MapHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) What do I need to do to completely prevent IIS from handling things? What I want is just to do Response.Writes in event handlers and async methods set up in HttpApplication.Init

  • WCF Paged Results & Data Export

    - by Ben
    I've walked into a project that is using a WCF service for the data tier. Currently, when data is needed for a grid, all rows are returned and the results are bound to a grid and the dataset is stuffed into a session variable for paging/sorting/rebinding. We've already hit a max message size problem, so I'm thinking it's time to convert from fetch and cache to fetch only the current page. Face value this seems easy enough, but there's a small catch. The user is allowed to export the entire result set at any point. This means that for grid viewing purposes fetching the current page is fine, but when they want to do an export, I still need to make a call for all data. This puts me back into the max message size issue. What is the recommended approach for this type of setup? We are currently using the wsHttpBinding... Thanks for any assistance.

  • Where can I find great Windows XP themes?

    - by Jon
    For the last couple of years I have used the Zune theme for Windows XP. Once the background picture is removed it is a very classy look for XP. Is there a place on the web where I can find other Windows themes are available to download and try? Do you have any recommendations for individual themes to use?

  • WSS and CAG , _layout pages break

    - by Mike
    Alright, I've searched everywhere and I cannot find the answer, due to the rarity of our setup. WSS 3.0/IIS 6.0/WinServer 2003 We have a sharepoint site that is in good shape, almost. Its TCP and SSL port are uncommon and need to be rerouted to work properly. This is where the Citrix Access Gateway (CAG) comes in play. It will redirect any request from URL (something.something.com) to the correct SSL port on the correct server. My AAM is configured to Default something.something.com and nothing else, since the CAG will provide the port. We use FBA, and require SSL. This works perfectly for everything that is safe or that is anything that an end user can see, but if I try to add a webpart, it errors out. Whereas if I add it internally, or bypass the CAG the webpart adds fine. The same goes for most of the _layouts pages, like _layouts/new.aspx. If I add a Link List/Doc library on the something.something.com, it errors out (Page cannot be displayed) and the page won't display, but if I try it with an internal address it will work fine. I found that if I am trying to add something or doing anything administrative, the site will navigate to the pages that I need to go to fine, but when i actually ADD something the URL will change from something.something.com to something.something.com:SSLport, thus erroring out the site. The URL with the SSL port shows on the Site URL when navigating to Site Settings. However, if I bypass the CAG, using the internal address the _layouts page works like a charm and i can add anything. All the CAG does is reroute a DNS request to the provided server and port. I've tried reextending the application, no luck same thing. I've tried changing the AAM to hide the port and the CAG rejects it. I've tried to recreate a new webapp/site collection with the same rules on the CAG, same thing occurs. Correct me if I'm wrong, and please provide me with some feedback and answers. Any suggestions would be very appreciated. Is it the CAG or the Alternate Access Mappings (AAM)?

  • Is there ever a reason to use Goto in modern .NET code?

    - by BenAlabaster
    I just found this code in reflector in the .NET base libraries... if (this._PasswordStrengthRegularExpression != null) { this._PasswordStrengthRegularExpression = this._PasswordStrengthRegularExpression.Trim(); if (this._PasswordStrengthRegularExpression.Length == 0) { goto Label_016C; } try { new Regex(this._PasswordStrengthRegularExpression); goto Label_016C; } catch (ArgumentException exception) { throw new ProviderException(exception.Message, exception); } } this._PasswordStrengthRegularExpression = string.Empty; Label_016C: ... //Other stuff I've heard all of the "thou shalt not use goto on fear of exile to hell for eternity" spiel. I always held MS coders in fairly high regard and while I may not have agreed with all of their decisions, I always respected their reasoning. So - is there a good reason for code like this that I'm missing, or was this code extract just put together by a shitty developer? I'm hoping there is a good reason, and I'm just blindly missing it. Thanks for everyone's input

  • PHP PDO bindValue() weird problem

    - by TheMagician
    <?php try { $db = new PDO("mysql:host=localhost;dbname=DBNAME", "USER", "PASSWD"); $stmt = $db->prepare("SELECT id, name FROM testdb ORDER BY time DESC LIMIT :index, 10"); $stmt->bindValue(":index", $_GET['index'], PDO::PARAM_INT); $stmt->execute(); while( $r = $stmt->fetch(PDO::FETCH_ASSOC) ) { echo var_dump($r); } } catch( PDOException $e ) { die("Exception"); } The problem is on this line: $stmt-bindValue(":index", $_GET['index'], PDO::PARAM_INT); And the specific parameter is the second one. The code as it is above doesn't work, it doesn't return anything so the while loop isn't executed. If I replace $_GET['index'] with a number, like 10, it works just fine, it returns 10 rows. Echoing $_GET['index'] displays a number, so it should pass a number. I've also tried bindParam, but the result is same. Why isn't this working?

  • Intermittently, IIS7 requests get stuck in WindowsAuthenticationModule

    - by rbeier
    Hi, We're running an IIS7 server hosting several dozen websites. Several of these websites are all part of the same legacy app we've developed. These sites all run the same code and run in the same app pool. Roughly once a month over the past few months, we've found that all requests for this app pool start hanging indefinitely. When this happens, we receive an alert and we recycle the app pool. After that, the sites start working again. This only ever affects this one app pool - never any others on the same server. A couple times, before recycling the pool, I've looked at the currently-executing requests in the worker process. They all show up as executing inside the WindowsAuthenticationModule. Which is strange, because the vast majority of the application does not require authentication. There is a small admin section which uses Windows auth... but all the other requests should be anonymous. Does anyone have any idea as to what might be causing this? There are several unusual things about the way these sites are set up. As I mentioned, they all run the same code - multiple sites point at the same physical directory. The only difference is the host header bindings. I'm not sure why there isn't just one site with all the host headers, but that's how it works. In several of these sites, the same physical directory is mapped at two levels - as the root of the site and again as an application within the site. So if a user goes to http://oursite.com/index.aspx, that maps to c:\files\oursite\index.aspx. If a user goes to http://oursite.com/foo/index.aspx, that also maps to c:\files\oursite\index.aspx. I think there is code which looks at the request URL and handles the two requests differently. This is strange because the same web.config ends up being interpreted as a site config file, and also as an application config file within the site. I don't know if this might be related to the authentication problem. If we can't find the cause, we're thinking of a few workarounds we could try: Move the admin section into a separate site, and give the client a new admin URL. Run that separate site in its own app pool. Then in the web.config shared by all the other sites, remove the WindowsAuthenticationModule. That way there should be no possibility of a hang within the WindowsAuthenticationModule. Try running all these sites in the classic pipeline instead of the integrated pipeline. They were working fine on our old IIS6 server... (If we get desperate) Set up a watchdog script which monitors the sites and auto-recycles the app pool when it detects that requests are getting stuck. What do you think? Thanks for your help, Richard

  • Spring: PropertyPlaceHolderConfigurer to set values for non-string/integer properties

    - by babyangel86
    Hi, All the examples I have seen where the PropertyPlaceHolderConfigurer is used seem to be setting simple values like Strings and ints. How do you use the PPC to set the values of classes. E.g. If i had a class signature Source(String name, DistributionSample batch, DistributionSample delay) How would I go about setting the batch and delay properties. There is also a small catch. DistributionSample is an abstract class. On the bright side, The class that is using the propertyPlaceHolder knows the beanName of the "Solid" class that needs to be instantiated. Any help would be much appreciated.

  • HttpWebRequest is extremely slow!

    - by Earlz
    Hello, I am using an open source library to connect to my webserver. I was concerned that the webserver was going extremely slow and then I tried doing a simple test in Ruby and I got these results Ruby program: 2.11seconds for 100 HTTP GETs C# library: 20.81seconds for 100 HTTP GETs I have profiled and found the problem to be this function: private HttpWebResponse GetRawResponse(HttpWebRequest request) { HttpWebResponse raw = null; try { raw = (HttpWebResponse)request.GetResponse(); //This line! } catch (WebException ex) { if (ex.Response is HttpWebResponse) { raw = ex.Response as HttpWebResponse; } } return raw; } The marked line is takes over 1 second to complete by itself while the ruby program making 1 request takes .3 seconds. I am also doing all of these tests on 127.0.0.1, so network bandwidth is not an issue. What could be causing this huge slow down?
