  • Increasing coverage with try-except-finally and a context-manager

    - by Daan Timmer
    This is the flow that I have in my program 277: try: 278: with open(r"c:\afile.txt", "w") as aFile: ...: pass # write data 329: except IOError as ex: ...: print ex 332: finally: 333: if os.path.exists(r"c:\afile.txt"): 334: shutil.copy(r"c:\afile.txt", r"c:\dest.txt") I've got all paths covered except for from line 278 to line 333 I got a normal happy-flow. I stubbed __builtin__.open to raise IOError when the open is called with said file name But how do I go from 278 to 333. Is this even possible? Additional information: - using coverage.py 3.4 (only listing 3.5, we can't currently upgrade to 3.5)

  • Google maps cluster manager

    - by Prashant
    Hello all I am using google maps in my application. I have to show 100 markers on map. First I prepared a markers array from these markers. When markers are added using addOverlay from markers array, it takes some time and they are being added in some animated way (in sequence). I want all of them to get added to map in a single shot, so no flickering effect. I tried MarkerClusterer but it shows a cluster of markers where the need be. Instead I want all the markers to appear, not a cluster. Only they should be added faster. var point = new GLatLng(latArr[i],lonArr[i]); var marker = new GMarker(point,markerOptions); markers[i] = marker; var markerCluster = new MarkerClusterer(map, markers); Any suggestions please? Thank you.

  • What is the purpose of Managers / Transactions?

    - by maxdj
    I'm building a spring application for the first time. I'm running into lots of problems with concurrency, and I suspect that there is something wrong with the way I'm managing the backend. The only difference I can see between my backend code and examples I've seen are manager classes. In my code, I have my model (managed by hibernate) and my DAOs on top of that to do CRUD/searching/etc on the models. In example code I have looked at, they never use the DAO directly. Instead, they use manager classes that call the DAOs indirectly. To me, this just seems like pointless code duplication. What are these manager classes for? I've read that they wrap my code in "transactions," but why would I want that?

  • Using Build Manager Class to Load ASPX Files and Populate its Controls

    - by Sandhurst
    I am using BuildManager Class to Load a dynamically generated ASPX File, please note that it does not have a corresponding .cs file. Using Following code I am able to load the aspx file, I am even able to loop through the control collection of the dynamically created aspx file, but when I am assigning values to controls they are not showing it up. for example if I am binding the value "Dummy" to TextBox control of the aspx page, the textbox remains empty. Here's the code that I am using protected void Page_Load(object sender, EventArgs e) { LoadPage("~/Demo.aspx"); } public static void LoadPage(string pagePath) { // get the compiled type of referenced path Type type = BuildManager.GetCompiledType(pagePath); // if type is null, could not determine page type if (type == null) throw new ApplicationException("Page " + pagePath + " not found"); // cast page object (could also cast an interface instance as well) // in this example, ASP220Page is a custom base page System.Web.UI.Page pageView = (System.Web.UI.Page)Activator.CreateInstance(type); // call page title pageView.Title = "Dynamically loaded page..."; // call custom property of ASP220Page //pageView.InternalControls.Add( // new LiteralControl("Served dynamically...")); // process the request with updated object ((IHttpHandler)pageView).ProcessRequest(HttpContext.Current); LoadDataInDynamicPage(pageView); } private static void LoadDataInDynamicPage(Page prvPage) { foreach (Control ctrl in prvPage.Controls) { //Find Form Control if (ctrl.ID != null) { if (ctrl.ID.Equals("form1")) { AllFormsClass cls = new AllFormsClass(); DataSet ds = cls.GetConditionalData("1"); foreach (Control ctr in ctrl.Controls) { if (ctr is TextBox) { if (ctr.ID.Contains("_M")) { TextBox drpControl = (TextBox)ctr; drpControl.Text = ds.Tables[0].Rows[0][ctr.ID].ToString(); } else if (ctr.ID.Contains("_O")) { TextBox drpControl = (TextBox)ctr; drpControl.Text = ds.Tables[1].Rows[0][ctr.ID].ToString(); } } } } } } }

  • Is there a free web file manager like Plesk or cPanel in ASP.Net

    - by Ron Klein
    I'm looking for a free, open-sourced web application written in C#/VB.Net on top of ASP.Net, which functions like Plesk or cPanel when it comes to (remote) file management. Something that simulates a regular FTP client, but actually displays web pages over HTTP, with the following functions: Create Folder Rename File/Folder Delete File/Folder Change Timestamp ("Touch") Move Archive etc. I saw a few commercial tools, but nothing when it comes to OSS. Any ideas? links?

  • how do you make a "concurrent queue safe" lazy loader (singleton manager) in objective-c

    - by Rich
    Hi, I made this class that turns any object into a singleton, but I know that it's not "concurrent queue safe." Could someone please explain to me how to do this, or better yet, show me the code. To be clear I want to know how to use this with operation queues and dispatch queues (NSOperationQueue and Grand Central Dispatch) on iOS. Thanks in advance, Rich EDIT: I had an idea for how to do it. If someone could confirm it for me I'll do it and post the code. The idea is that proxies make queues all on their own. So if I make a mutable proxy (like Apple does in key-value coding/observing) for any object that it's supposed to return, and always return the same proxy for the same object/identifier pair (using the same kind of lazy loading technique as I used to create the singletons), the proxies would automatically queue up the any messages to the singletons, and make it totally thread safe. IMHO this seems like a lot of work to do, so I don't want to do it if it's not gonna work, or if it's gonna slow my apps down to a crawl. Here's my non-thread safe code: RMSingletonCollector.h // // RMSingletonCollector.h // RMSingletonCollector // // Created by Rich Meade-Miller on 2/11/11. // Copyright 2011 Rich Meade-Miller.

  • Start PyGTK cellrenderer edit from code

    - by mkotechno
    I have a treeview with an editable CellRendererText: self.renderer = gtk.CellRendererText() self.renderer.set_property('editable', True) But now I need to launch the edition from code instead from user, this is to focus the user attention in the fact he just created a new row and needs to be named. I tried this but does not work: self.renderer.start_editing( gtk.gdk.Event(gtk.gdk.NOTHING), self.treeview, str(index), gtk.gdk.Rectangle(), gtk.gdk.Rectangle(), 0) Neither does not throw errors, but the documentation about for what is each argument is not clear, in fact I really don't know if start_editing method is for this. All suggestions are welcome, thanks.

  • AS3 Transition Manager problem

    - by Mirko
    I am using the TransitionManager class to pixel dissolve an image in an image gallery XML driven. It always stops half way through the animation...I hate Adobe Tween engines, I always used TweenMax without (almost) any problem but I would like to have the pixel dissolve effect. var myTM:TransitionManager = new TransitionManager(container_mc); myTM.addEventListener("allTransitionsOutDone",swapContent); myTM.startTransition({ type:PixelDissolve, direction:Transition.OUT, duration:1,easing:None.easeOut,xSections:200, ySections:200 }); Any suggestion?

  • How to reschedule Alarm Manager on Preference Change

    - by Priyank
    Hi, I have an Android Service. When a phone boots up, a broadcast receiver receives a notification and it schedules the service to run repeatedly at a gap of X minutes. Henceforth After every X minutes another broadcast receiver gets those notifications and kicks the service off, which does it's job and quits. So far so good. Now I want those X minutes to be configurable. I have a perf.xml similar to what is given at the link below. This XML captures all my preferences along with that of service timer. http://android-journey.blogspot.com/2010/01/for-almost-any-application-we-need-to.html Now when user changes preferences; how can I reschedule the alarm? Is there a way I can set a listener on preferences change? I have used only XML files to speficy preferences screen. Any ideas will be welcome. Cheers

  • What's the best self-tracking software for Linux?

    - by trench
    I'm looking for a way to track myself and receive quality data upon which I can write future scripts/programs. For example, I use Google Reader a lot. I'd like to track the hrefs that garner my clicks. Further, I'd like to drop all of the words of each href into a database where they can be stacked in a hierarchical manner. At the end of the week I want to know that "Ubuntu" garnered 448 clicks and "Cheetos" garnered 2. :) That's just one example... I'd like this tracking and data-collecting to extend beyond my browser. I know writing something to do this myself wouldn't be too awfully difficult but if something already exists I'd happily use it. Thanks in advance. Primary OS: Ubuntu 10.04

  • windows I/O manager - IRP's classification in read-like and write-like

    - by clyfe
    I am writing a windows filesystem minifilter driver that must fail IRP's in a preoperation callback. How can I find out from the callback parameters if the operation is read-like ( only reads data ) or it's write-like ( modifies data on the disk - write, delete etc ) ? I'm thinking on: Data->Iopb->TargetFileObject->ReadAccess Data->Iopb->TargetFileObject->WriteAccess But I'm not sure, I think thees are available only in postoperation callback. The documentation is really cumbersome. Code sample: FLT_PREOP_CALLBACK_STATUS Fail ( __inout PFLT_CALLBACK_DATA Data, __in PCFLT_RELATED_OBJECTS FltObjects, __deref_out_opt PVOID *CompletionContext ) { FLT_PREOP_CALLBACK_STATUS status = FLT_PREOP_SUCCESS_NO_CALLBACK; if ( IS WRITE_LIKE(Data, FltObjects) ) { // ??? HOW DO I FIND OUT???? if( FLT_IS_FASTIO_OPERATION(Data) ){ status = FLT_PREOP_DISALLOW_FASTIO; } else { status = FLT_PREOP_COMPLETE; } Data->IoStatus.Status = STATUS_ACCESS_DENIED; Data->IoStatus.Information = 0; return status; } return status; }

  • python VTE Terminal weirdness

    - by mykhal
    i'm trying to use the terminal from python VTE binding (python-vte from debian squeeze) as a virtual terminal emulator (just for ANSI/control chars text processing) in interactive python console, everything looks (almost) all right: >>> import vte >>> term = vte.Terminal() >>> term.feed("a\nb") >>> print repr(term.get_text(lambda *a: True).rstrip()) 'a\n b' however, launching this code (little modified) as python script, different result is yielded: $ python vte_wiredness_1.py '' strangely enough, pasting the code back into the (new) interactive python session also yields empty string: >>> import vte >>> term = vte.Terminal() >>> term.feed("a\nb") >>> print repr(term.get_text(lambda *a: True).rstrip()) '' >>> first thing caming on my mind was that the only difference between the two cases is the timing - there had to be some delay before get_text. unfortunately, preluding get_text with some seconds sleep did not help then i thought it has something to do with X window environment. but the results are the same pure linux console (with some warning on missing graphics). i wonder what causes such an unpredictable behavior (interactive console - pasted vs typed, and it's not the delay.. ant the interactive console has nothing to do with the vte terminal object.. i guess) can someone explain what is happening? is it possible to use the VTE Term such way? that the "b" letter in the output is preceded by the space, is another strangeness (all consecutive lines are preceded by more spaces.. looks like I have to send carriage return before the string.) (the lambda *a: True get_text method argument i'm using is a dummy callback, it's is some SlotSelectedCallback.. for its explanation i'd be grateful as well :) )

  • Popup Dialog Box Manager using PureMVC

    - by webwise
    I am developing a a game in Flash using the PureMVC framework. From time to time I need to show dialog pop-up window to get a user response back (e.g. "Cancel", "OK" and other kinds of asynchronous user feedback) while "locking" the background for interactivity. I need some management for my pop-ups: all pop-up notifications should be stacked up, so that if two (or more) pop-up messages are initiated at the same time I show them one by one. What's the best practice here? Should I employ a proxy to manage my pop-ups (sounds unreasonable). How do I get feedback back from my dialog? using notifications?

  • C# Configuration Manager . ConnectionStrings

    - by Yoda
    I have a console app containing an application configuration file containing one connection string as shown below: <configuration> <connectionStrings> <add name="Target" connectionString="server=MYSERVER; Database=MYDB; Integrated Security=SSPI;" /> </connectionStrings> </configuration> When I pass this to my Connection using: ConfigurationManager.ConnectionStrings[1].ToString() I have two values in there, hence using the second in the collection, my question is where is this second coming from? I have checked the Bin version and original and its not mine! Its obviously a system generated one but I have not seen this before? Can anyone enlighten me? The mystery connection string is: data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true This isn't a problem as such I would just like to know why this is occuring? Thanks in advance! For future reference to those who may or may not stumble on this, after discovering the machine.config its become apparent it is bad practice to refer to a config by its index as each stack will potentially be different, which is why "Keys" are used. Cheers all!

    I need to disable and enable the taskmanager from my application. I am doing this for my Kiosk application. I know i can do this by changing the Key in registry using below code. But the problem is my kiosk application will run in limited user account which does not allow the application to change key in registry level. Code working perfectly in Administrator account : RegistryKey regkey; string keyValueInt = "1"; string subKey = "Software\\Microsoft\\Windows\\CurrentVersion\\Policies\\System"; regkey = Registry.CurrentUser.CreateSubKey(subKey); regkey.SetValue("DisableTaskMgr", keyValueInt); regkey.Close(); How can i achieve this in Limited user account ?

  • is there any cross platform process manager tool

    - by lvlv
    I need a program that is able to launch a set of processes according to a schedule/configuration; the program would run in the background and restart the processes in case they crash. There are standard tools for this kind of task on both windows and unix - what I need is a cross platform program which could run on different operating systems using the same configuration. A portable C/C++ library which implements the basic functionality (i.e. create processes, signal process termination events and all that) would be ok too.
