  • Application window as polygon texture?

    - by nekome
    Is there a way, or method, to have some application rendered as texture in 3D scene on some polygon, and also have full interactivity with it? I'm talking about Windows platform, and maybe OpenGL but I guess it doesn't matter is it OGL or DX. For example: I run Calculator using WINAPI functions (preferably hidden, not showing on desktop) and I want to render it inside 3D scene on some polygon but still be able to type or click buttons and have it respond. My idea to realize this is to have WINAPI take screenshot (or render it to memory if possible) of that Calculator and pass it to OpenGL as texture for each frame (I'm experimenting with SDL through pygame) and for mouse interactivity to use coordination translation and calculate where on application window it would act, and then use WINAPI functions such as SetCursorPos to set cursor ant others to simulate click or something else. I haven't found any tutorials with topic similar to this one. Am I on a right track? Is there better way to do this if possible at all?

  • grep from a log file to get count

    - by subodh1989
    I have to get certain count from files. The grep statement i am using is like this : counter_pstn=0 completed_count_pstn=0 rec=0 for rec in `(grep "merged" update_completed*.log | awk '{print $1}' | sed 's/ //g' | cut -d':' -f2)` do if [ $counter_pstn -eq 0 ] then completed_count_pstn=$rec else completed_count_pstn=$(($completed_count_pstn+$rec)) fi counter_pstn=$(($counter_pstn+1)) done echo "Completed Orders PSTN Primary " $completed_count_pstn But the log file contains data in this format : 2500 rows merged. 2500 rows merged. 2500 rows merged. 2500 rows merged.2500 rows merged. 2500 rows merged. 2500 rows merged. As a result , it is missing out the count of one merge(eg on line 4 of output).How do i modify the grep or use another function to get the count. NOTE that the 2500 number maybe for different logs. So we have to use "rows merged" pattern to get the count. i have tried -o ,-w grep options,but it is not working. Expected output from above data: 17500 Actual output showing : 15000

  • Accessing Application Scoped Bean Causes NullPointerException

    - by user2946861
    What is an Application Scoped Bean? I understand it to be a bean which will exist for the life of the application, but that doesn't appear to be the correct interpretation. I have an application which creates an application scoped bean on startup (eager=true) and then a session bean that tries to access the application scoped bean's objects (which are also application scoped). But when I try to access the application scoped bean from the session scoped bean, I get a null pointer exception. Here's excerpts from my code: Application Scoped Bean: @ManagedBean(eager=true) @ApplicationScoped public class Bean1 implements Serializable{ private static final long serialVersionUID = 12345L; protected ArrayList<App> apps; // construct apps so they are available for the session scoped bean // do time consuming stuff... // getters + setters Session Scoped Bean: @ManagedBean @SessionScoped public class Bean2 implements Serializable{ private static final long serialVersionUID = 123L; @Inject private Bean1 bean1; private ArrayList<App> apps = bean1.getApps(); // null pointer exception What appears to be happening is, Bean1 is created, does it's stuff, then is destroyed before Bean2 can access it. I was hoping using application scoped would keep Bean1 around until the container was shutdown, or the application was killed, but this doesn't appear to be the case.

  • How can I modify the application file of an application that is currently running (on Linux)?

    - by Hach-Que
    I have an application running called AppFS. This application has an ext2 filesystem just attached to the end of the file (it's positioned so that the application binary exists in a 1MB spacing area, followed by the ext2 data). Now I've got FUSE embedded in the program and I've managed to extract the filesystem out of the application data into a temporary file so that FUSE can mount / use it. The problem I have now is writing the temporary file back into the application file. I get "Text file busy" presumably because the application has locked itself and won't let writes occur. Is there a way I can force the file to become unlocked so I can write data to it? (It's important to note that I'm not changing the application binary area - just rewriting the ext2 component.) It needs to be unlocked without requiring root permissions (unlocked by the same user who started the application).

  • Python - How can I make this code asynchronous?

    - by dave
    Here's some code that illustrates my problem: def blocking1(): while True: yield 'first blocking function example' def blocking2(): while True: yield 'second blocking function example' for i in blocking1(): print 'this will be shown' for i in blocking2(): print 'this will not be shown' I have two functions which contain while True loops. These will yield data which I will then log somewhere (most likely, to an sqlite database). I've been playing around with threading and have gotten it working. However, I don't really like it... What I would like to do is make my blocking functions asynchronous. Something like: def blocking1(callback): while True: callback('first blocking function example') def blocking2(callback): while True: callback('second blocking function example') def log(data): print data blocking1(log) blocking2(log) How can I achieve this in Python? I've seen the standard library comes with asyncore and the big name in this game is Twisted but both of these seem to be used for socket IO. How can I async my non-socket related, blocking functions?

  • Automatically restarting Erlang applications

    - by Nick
    I recently ran into a bug where an entire Erlang application died, yielding a log message that looked like this: =INFO REPORT==== 11-Jun-2010::11:07:25 === application: myapp exited: shutdown type: temporary I have no idea what triggered this shutdown, but the real problem I have is that it didn't restart itself. Instead, the now-empty Erlang VM just sat there doing nothing. Now, from the research I've done, it looks like there are other "start types" you can give an application: 'transient' and 'permanent'. If I start a Supervisor within an application, I can tell it to make a particular process transient or permanent, and it will automatically restart it for me. However, according to the documentation, if I make an application transient or permanent, it doesn't restart it when it dies, but rather it kills all the other applications as well. What I really want to do is somehow tell the Erlang VM that a particular application should always be running, and if it goes down, restart it. Is this possible to do? (I'm not talking about implementing a supervisor on top of my application, because then it's a catch 22: what if my supervisor process crashes? I'm looking for some sort of API or setting that I can use to have Erlang monitor and restart my application for me.) Thanks!

  • How to concatenate all commit messages from subversion into one text file with no metadata?

    - by user144182
    I would like to take all the commit messages in my subversion log and just concatenate them into one text file. Each commit message has this format: - r1 message - r1 message - r1 message What I would like is something like: - r1 message - r1 message - r2 message - r2 message - r3 message [...] - r1000 message Update I thought the above was clear, but what I don't want in the log is this type of info: r2130 | user| 2010-03-19 10:36:13 -0400 (Fri, 19 Mar 2010) | 1 line No meta data, I simply want the commit messages.

  • How to turn off the binary log for mysqld_multi instances?

    - by netvope
    MySQL supports running multiple mysqld on the same server. One of the ways is to use mysqld_multi. If the default MySQL server instance (as configured in the [mysqld] section in my.cnf) uses log-bin, it enables the binary log for all the other instances ([mysqld1], [mysqld2], etc). How can we override the setting for the other instances? We tried putting log-bin= or log-bin=OFF under [mysqld1], but that won't disable the binary log.

  • Is segfault signal always sent to application

    - by noonex
    My application usually crashes and prints stack to log if received segfault signal. But in some environment the 'dmesg' shows segfault messages related to my application, but application uptime is much older. Can segfault be suppressed and application doesn't receive signal? Or what errors from dmesg can mean ?

  • Repeated requests on our server?

    - by pitty.platsch
    I encountered something strange in the access log of our Apache server which I cannot explain. Requests for webpages that I or my colleagues do from the office's Windows network get repeated by another IP (that we don't know) a couple of seconds later. The user agent repeating our requests is Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; .NET CLR 2.0.50727; .NET CLR 3.0.04506.648; .NET CLR 3.5.21022; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729; InfoPath.2) Has anyone an idea? Update: I've got some more information now. The referrer of the replicate is set to the URL I requested before and it's not the exact same request as the protocol version is changed from 'HTTP/1.1' to 'HTTP/1.0'. The IP is not just one, it's just one of a subnet (80.40.134.*). It's just the first request to a resource that's get repeated, so it seems the "spy" is building up some kind of cache of visited places. The repeater is also picky. I tried randomly URLs with different HTTP status codes and different file patterns. 301s and 200s are redone, 404s not. Image extensions seem to be ignored. While doing my tests I discovered that this behavior seems to be common as I found other clients visiting just after the first requests: 66.249.73.184 - - [25/Oct/2012:10:51:33 +0100] "GET /foobar/ HTTP/1.1" 200 10952 "-" "Mediapartners-Google" 50.17.125.180 - - [25/Oct/2012:10:51:33 +0100] "GET /foobar/ HTTP/1.1" 200 41312 "-" "Mozilla/5.0 (compatible; proximic; +http://www.proximic.com/info/spider.php)" I wasn't aware about this practice, so I don't see it that much as a threat anymore. I still want to find out who this is, so any further help is appreciated. I'll try later if this also happens if I query some other server where I have access to the access logs and will update here then.

  • Ubuntu's gui "Open With" command is not memorizing the application

    - by Tom Brito
    In Ubuntu, when we right-click a icon and use "open with", there is an option to remember that application for that file's type. For some reason, my system is no more memorizing the application (I think it was aftare some update). And, even when I have already used the "open with" command, the application is not showing in the "open with" list, so I have, everytime, to go to "open with"-"Other Application". Any hint to solve this?

  • Access/update Telerik RadGrid item values in code-behind before ODS event handler

    - by Brent
    Hi there, I need to update some of the values of the item being edited in my code-behind based on some values in a custom Edit Form on our Rad Grid. Can I access the item (and update some values) from one of the Grid's event handlers? Currently I'm storing the values in temporary variables and then injecting the new values in the ObjectDataSource's Inserting/Updating event handlers, but it would be much nicer if I could do it all in one spot. (I can't do it all in the ObjectDataSource event handlers as I can't access the controls inside my Grid's Edit Form.) I've been playing with the ExtractValues and UpdateValues methods of the GridEditableItem object, but I'm not having any luck. Any tips would be greatly appreciated :)
