  • Storing Configurations into Active Direcotry Application Mode

    - by Khurram Aziz
    I have a network devices polling and do actions kind of app; currently it keeps the configuration (which devices to poll, what kind of device, ip, login, password etc) in the database. My network administrator wants that this information is stored in some LDAP server so that he maintain single store of configuration which he himself can use in other apps/scripts etc. I am looking for some article that walks me through setting up ADAM/AD LDS for storing configuration by authoring custom schema etc and how to setup some authentication infrastructure to protect the data.

  • Message pump in .NET Windows service

    - by Pickles
    I have a Windows Service written in C# that handles all of our external hardware I/O for a kiosk application. One of our new devices is a USB device that comes with an API in a native DLL. I have a proper P/Invoke wrapper class created. However, this API must be initialized with an HWnd to a windows application because it uses the message pump to raise asynchronous events. Besides putting in a request to the hardware manufacturer to provide us with an API that does not depend on a Windows message pump, is there any way to manually instantiate a message pump in a new thread in my Windows Service that I can pass into this API? Do I actually have to create a full Application class, or is there a lower level .NET class that encapsulates a message pump?

  • How do I determine if a JDialog has children?

    - by Morinar
    I've got a custom window class that is a couple levels down extending a JDialog. We have windows that we create and sometimes we create new windows as children of existing windows using the constructor that takes a parent argument. I need to put some code somewhere in our custom class that does something different depending on whether not the window has children. I know of getParent(), etc, and I can see that I can loop through the components of the window, but for the life of me, I can't seem to figure out how to determine whether or not my current window has any child windows. Is there a way to do this? Any help is, as always, much appreciated.

  • Is there a way to watch all COM activity on a computer?

    - by Fake Name
    I'm trying to deal with a piece of specialized hardware, that presents it's interface as a COM object, using win32com in Python. However, the documentation for how to actually set up the hardware through the COM object is sparse (it requires a significant amount of initialization), and entirely oriented at using a bunch of pre-built libraries for Visual Studio, which are not accessible through python. That said, is there any way to watch all local COM activity, so I can sort through the activity logs to try and figure out how the existing demo programs properly initialize the hardware, and replicate the behavior in my python script? Ideally, there would be something in the vein of wireshark for doing this. Note: I have very little (read: basically no) experience using COM, as my focus is mostly embedded hardware (and a little python dev on the side). However, I'm stuck with this particular device.

  • On WindowsMobile, how can i tell what other processes are reserving shared memory space?

    - by glutz78
    On WindowMobile 6.1, I am using VirtualAlloc to reserve 2MB chunks, which will return me an address from the large shared memory area so allocations do not count against my per process virtual space. (doc here: http://msdn.microsoft.com/en-us/library/aa908768.aspx) However, on some devices i notice that I am not able to reserve memory after a certain point. VirtualAlloc will return NULL (getlasterror() says out of memory). The only explanation for this that I see is that another process has already reserved a bunch of memory and my process is therefore unable to. Any idea where I can find a tool to show me the shared mem region of a WM device? Thanks.

  • Custom component which displays voice recognition button if available

    - by steff
    Hi evereyone, I'd like to create a custom component which supports voice recognition. It will primarily be an extended EditText which should show the microphone button for voice recognition if it is available. I wanted to to look at the search app-widget on the homescreen but I don't find it in the source. This is intended to use the voice recognition as some sort of dictation device, i.e. the user does not have to type but use his voice instead. So could anyone please point me in some direction? Thanks in advance, Steff

  • Socket Bind Error

    - by rantravee
    Hi, I have a test application that opens a socket , sends something through this socket and then closes it . This is done in a loop for 5-10.000 times. The thing is that after 3,4000 iterations I get an error of this type : enter code here java.net.BindException: Address already in use: connect I even set the socket to be used immediattly, but the error persists enter code here try { out_server.write(m.ToByteArray()); socket_server.setReuseAddress(true); socket_server.close(); } catch(Exception e) { e.printStackTrace(); System.out.println(i+" unable to register with the server"); } What could I do to fix this ?

  • Modelling boost::Lockable with semaphore rather than mutex (previously titled: Unlocking a mutex fr

    - by dan
    I'm using the C++ boost::thread library, which in my case means I'm using pthreads. Officially, a mutex must be unlocked from the same thread which locks it, and I want the effect of being able to lock in one thread and then unlock in another. There are many ways to accomplish this. One possibility would be to write a new mutex class which allows this behavior. For example: class inter_thread_mutex{ bool locked; boost::mutex mx; boost::condition_variable cv; public: void lock(){ boost::unique_lock<boost::mutex> lck(mx); while(locked) cv.wait(lck); locked=true; } void unlock(){ { boost::lock_guard<boost::mutex> lck(mx); if(!locked) error(); locked=false; } cv.notify_one(); } // bool try_lock(); void error(); etc. } I should point out that the above code doesn't guarantee FIFO access, since if one thread calls lock() while another calls unlock(), this first thread may acquire the lock ahead of other threads which are waiting. (Come to think of it, the boost::thread documentation doesn't appear to make any explicit scheduling guarantees for either mutexes or condition variables). But let's just ignore that (and any other bugs) for now. My question is, if I decide to go this route, would I be able to use such a mutex as a model for the boost Lockable concept. For example, would anything go wrong if I use a boost::unique_lock< inter_thread_mutex for RAII-style access, and then pass this lock to boost::condition_variable_any.wait(), etc. On one hand I don't see why not. On the other hand, "I don't see why not" is usually a very bad way of determining whether something will work. The reason I ask is that if it turns out that I have to write wrapper classes for RAII locks and condition variables and whatever else, then I'd rather just find some other way to achieve the same effect. EDIT: The kind of behavior I want is basically as follows. I have an object, and it needs to be locked whenever it is modified. I want to lock the object from one thread, and do some work on it. Then I want to keep the object locked while I tell another worker thread to complete the work. So the first thread can go on and do something else while the worker thread finishes up. When the worker thread gets done, it unlocks the mutex. And I want the transition to be seemless so nobody else can get the mutex lock in between when thread 1 starts the work and thread 2 completes it. Something like inter_thread_mutex seems like it would work, and it would also allow the program to interact with it as if it were an ordinary mutex. So it seems like a clean solution. If there's a better solution, I'd be happy to hear that also. EDIT AGAIN: The reason I need locks to begin with is that there are multiple master threads, and the locks are there to prevent them from accessing shared objects concurrently in invalid ways. So the code already uses loop-level lock-free sequencing of operations at the master thread level. Also, in the original implementation, there were no worker threads, and the mutexes were ordinary kosher mutexes. The inter_thread_thingy came up as an optimization, primarily to improve response time. In many cases, it was sufficient to guarantee that the "first part" of operation A, occurs before the "first part" of operation B. As a dumb example, say I punch object 1 and give it a black eye. Then I tell object 1 to change it's internal structure to reflect all the tissue damage. I don't want to wait around for the tissue damage before I move on to punch object 2. However, I do want the tissue damage to occur as part of the same operation; for example, in the interim, I don't want any other thread to reconfigure the object in such a way that would make tissue damage an invalid operation. (yes, this example is imperfect in many ways, and no I'm not working on a game) So we made the change to a model where ownership of an object can be passed to a worker thread to complete an operation, and it actually works quite nicely; each master thread is able to get a lot more operations done because it doesn't need to wait for them all to complete. And, since the event sequencing at the master thread level is still loop-based, it is easy to write high-level master-thread operations, as they can be based on the assumption that an operation is complete when the corresponding function call returns. Finally, I thought it would be nice to use inter_thread mutex/semaphore thingies using RAII with boost locks to encapsulate the necessary synchronization that is required to make the whole thing work.

  • jCarousel, IE6 and Fixed Width

    - by Pat Long - Munkii Yebee
    We are using jCarousel on our websites to display images. Simple enough. We have fairly flexible layouts so the carousels are not always the same width. FF, IE7+, Chrome, Safari etc work perfectly well taking up the space available. However IE6 ends up sending the jCarousel script into a loop and warns that a script is stopping the page from loading correctly. To stop IE6 from failing we are having to specify a fixed width in CSS for the carousel container. Is this a problem that others have had with IE6 and jCarousel?

  • jquery noConflict not working in IE8 only

    - by slik
    I have a website using the prootype framework and I am looking to use a jquery plugin. Everything works just not in IE8. It works in ie7 which amazes me. Any idea what maybe wrong? jQuery.noConflict(); function OpenUp(sURL){ window.open(sURL,null,'height=560,width=820,status=yes,toolbar=yes,menubar=yes,location=yes,resizable=yes,scrollbars=yes',false); } jQuery(document).ready(function($) { $("head").append("<link>"); css = $("head").children(":last"); css.attr({ rel: "stylesheet", type: "text/css", href: "/my/docs/jquery.simplyscroll.css" }); $("#scroller").simplyScroll({ autoMode: 'loop', framerate: 1, speed: 1 }); }); I also tired the following: var $j = jQuery.noConflict(); var j = jQuery.noConflict(); everythig works just not in IE8 alone.

  • Can't get Xdebug to work on Windows 7

  • How do I perform a batch insert in Django?

    - by Thierry Lam
    In mysql, you can insert multiple rows to a table in one query for n 0: INSERT INTO tbl_name (a,b,c) VALUES(1,2,3),(4,5,6),(7,8,9), ..., (n-2, n-1, n); Is there a way to achieve the above with Django queryset methods? Here's an example: values = [(1, 2, 3), (4, 5, 6), ...] for value in values: SomeModel.objects.create(first=value[0], second=value[1], third=value[2]) I believe the above is calling an insert query for each iteration of the for loop. I'm looking for a single query, is that possible in Django?

  • Is writing to a socket an arbitrary limitation of the sendfile() syscall?

    - by Sufian
    Prelude sendfile() is an extremely useful syscall for two reasons: First, it's less code than a read()/write() (or recv()/send() if you prefer that jive) loop. Second, it's faster (less syscalls, implementation may copy between devices without buffer, etc...) than the aforementioned methods. Less code. More efficient. Awesome. In UNIX, everything is (mostly) a file. This is the ugly territory from the collision of platonic theory and real-world practice. I understand that sockets are fundamentally different than files residing on some device. I haven't dug through the sources of Linux/*BSD/Darwin/whatever OS implements sendfile() to know why this specific syscall is restricted to writing to sockets (specifically, streaming sockets). I just want to know... Question What is limiting sendfile() from allowing the destination file descriptor to be something besides a socket (like a disk file, or a pipe)?

  • [C#] Onpaint events (invalidated) changing execution order after a period normal operation (runtime)

    - by Luke Mcneice
    Hi all, I have 3 data graphs that are painted via the their paint events. When I have data that I need to insert into the graph I call the controls invalidate() command. The first control's paint event actually creates a bitmap buffer for the other 2 graphs to avoid repeating a long loop. So the invalidate commands are in a specific order (1,2,3). This works well, however when the graphed data reaches the end of the graph window (PictureBox) where the data would normally start scrolling, the paint events begin firing in the wrong order (2,3,1). has anyone came across this before? why might this be happening?

  • OpenCV in Python can't scan through pixels

    Hi everyone, I'm stuck with a problem of the python wrapper for OpenCv. I have this function that returns 1 if the number of black pixels is greater than treshold def checkBlackPixels( img, threshold ): width = img.width height = img.height nchannels = img.nChannels step = img.widthStep dimtot = width * height data = img.imageData black = 0 for i in range( 0, height ): for j in range( 0, width ): r = data[i*step + j*nchannels + 0] g = data[i*step + j*nchannels + 1] b = data[i*step + j*nchannels + 2] if r == 0 and g == 0 and b == 0: black = black + 1 if black >= threshold * dimtot: return 1 else: return 0 The loop (scan each pixel of a given image) works good when the input is an RGB image...but if the input is a single channel image I get this error: for j in range( width ): TypeError: Nested sequences should have 2 or 3 dimensions The input single channel image (called 'rg' in the next example) is taken from an RGB image called 'src' processed with cvSplit and then cvAbsDiff cvSplit( src, r, g, b, 'NULL' ) rg = cvCreateImage( cvGetSize(src), src.depth, 1 ) # R - G cvAbsDiff( r, g, rg ) I've also already noticed that the problem comes from the difference image got from cvSplit... Anyone can help me? Thank you

  • Javascript - Concatenate Multiple NodeLists Together

    - by Emtucifor
    I was originally asking for an elegant way to simulate the Array.concat() functionality in IE or older browsers, because it seemed that concat was not supported. Only, of course it is and the reason the object didn't support it is because it wasn't an array. Oops! getElementsByTagName returns a NodeList, not an array. The real question, then, is: what's a good way to get a single list of all the form elements in a document (input, select, textarea, button) to loop through them? An array isn't required... a single NodeList would be perfect, too. Note that I'm using IE6 as this is for a corporate intranet (soon IE8 though).

    Hi, How to copy or duplicate gtk widgets? In my application I have one huge GtkComboBox created with one long for loop which eats up so much of time and I am using this combo at two places in one single screen. So, what I want to do is create this combo for one time and duplicate/copy it in another one so it will save my time. If I try to add same combo box pointer two times, gtk gives me error "child-paren != NULL" cause in gtk widget can have only single parent. So what to do? Thanks, PP.

    Right now I'm using Eclipse for Android development, but my computer is kind of old and I like responsive development environments. I've tried using VIM, Emacs and TextMate but I'm missing every feature in the Eclipse Android plugin: Auto generate R class Check for errors & warnings on code Auto completion Deploy to device or emulator Integrate with DDMS The list goes to infinity ... I know Eclipse is the best for what I want to do, but if I want to use any editor, what do you recommend to achieve a not so frustrating Android development experience?

  • Workaround iPhone's browser not honoring the <label> element

    - by Sorin Comanescu
    Hi, Just ran into this recently and I thought it'd be helpful to share. The HTML <label> element is supported in a weird way by iPhone's (v3) browser. Try this: <input type="checkbox" id="chkTest" /><label for="chkTest">Click me!</label> Tapping the "Click me!" label has no effect, the checkbox is not checked. Lack of support in a touch device for <label> elements puzzled me and I tried to overcome this issue by using javascript. The surprise came when a I noticed a void javascript like the one below also did the trick: <input type="checkbox" id="chkTest" /><label for="chkTest" onclick="javascript:void(0);">Click me!</label> HTH Further info: Also works with an empty handler: onclick="" Disabling JavaScript inactivates again the label, even if using the empty handler.

  • CheckboxList not setting Selected with Viewstate disabled

    - by Earlz
    I have a CheckboxList that seems to load and do everything right, except for when I do a postback, it will not have the Item.Selected property set. I have viewstate disabled for the entire page. I load it like so(inside Page_Load on every load): foreach (DataRow service in d.Tables[0].Rows) { cblServices.Items.Add(new ListItem((string)service["description"], service["id"].ToString())); } My markup is simple: <asp:CheckBoxList runat="server" ID="cblServices" Width="300px"></asp:CheckBoxList> and then, I use basically something like this(in a _Click serverside event for a button) foreach(ListItem item in cblServices.Items){ if(item.Selected){ MyLabel.Text+="selected: "+item.Value+item.Text; } } and MyLabel never has any text added to it. I can verify with the debugger that it does reach the _Click's foreach loop, but no item is ever selected. What could be the cause of this?

  • Java, searching through folders to match a name

    - by Nick
    Hi folks, I using java to search for a file or folder that matches a specific case. For instance i want to search through all the files and folders and iterate through them as many times as necessary untill i find a result. The catch I searching for files and folders through a binary image of a file system. This means i doubt there are any preexisting classes such java.file.* to do it for me. If it helps i can tell you that i can tell the difference between files and folders easily enough. (a folder is flagged as 0x20) The only way i can think of is to do a standard loop and iterated several times but this limits me if a file or folder is several folders deep. All input greatly welcome

  • How do I check if a user is authenticated with NickServ using POE::Component::IRC::State in Perl?

    - by Troy
    I'm trying to test whether a user is registered on FreeNode. nick_info() doesn't seem to return information about this, so I want to use $irc-yield(whois = $nick); and then grab the irc_whois event's reply. The problem is that I want to wait until this event is fired, so I created a global variable $whois_result and wrote a sub like this: sub whois { my $nick = $_[0]; $whois_result = 0; $irc->yield(whois => $nick); while($whois_result == 0) { } return $whois_result; } with the irc_whois handler looking like: sub on_whois { $whois_result = $_[ARG0]; print "DEBUG: irc_whois fired.\n"; } Unfortunately, the event can't fire while the loop is running so this hangs. I'm sure there's a better way to do this, but I'm not familiar enough with this kind of programming to know. Any help would be greatly appreciated.

  • Passing Activity to non-activity object properly

    - by rayman
    In my app ive got a non-activity object which it's role is being a manager class. many times i need to pass "source activity" to methods as parameter to that manager class in order to make some operations on that activity. for exaple let's assume we have MyActivity which gotta do some toast. so i have this manager class called MyManager, and i have this method in it raiseToast(Activity sourceActivity) { Toast.makeText(sourceActivity, demo, Toast.LENGTH_LONG).show(); } and from Myactivity class we calling that method this way: MyManager manager=new MyManager(); manager.raitetoast(MyActivity.this); it works fine. what I'm asking here, is this a proper way to pass an Activity as parameter to a non-activity object? I'm having a memory leaks on real device(not the emulator), I wonder if this could also causing any reason for that? Thanks Idan.
