  • Ant path/pathelement not expanding properties correctly

    - by Jonas Byström
    My property gwt.sdk expands just fine everywhere else, but not inside a path/pathelement: <target name="setup.gwtenv"> <property environment="env"/> <condition property="gwt.sdk" value="${env.GWT_SDK}"> <isset property="env.GWT_SDK" /> </condition> <property name="gwt.sdk" value="/usr/local/gwt" /> <!-- Default value. --> </target> <path id="project.class.path"> <pathelement location="${gwt.sdk}/gwt-user.jar"/> </path> <target name="libs" depends="setup.gwtenv" description="Copy libs to WEB-INF/lib"> </target> <target name="javac" depends="libs" description="Compile java source"> <javac srcdir="src" includes="**" encoding="utf-8" destdir="war/WEB-INF/classes" source="1.5" target="1.5" nowarn="true" debug="true" debuglevel="lines,vars,source"> <classpath refid="project.class.path"/> </javac> </target> For instance, placing an echo of ${gwt.sdk} just above works, but not inside "project.class.path". Is it a bug, or do I have to do something that I'm not? Edit: I tried moving the property out from target setup.gwtenv into "global space", that helped circumvent the problem.

  • Future raid update in a NAS and HP ProLiant alternatives

    - by edwardmlyte
    I'm thinking of buying the HP ProLiant MicroServer*. My question is if I just put a single 2TB drive, how easy would it be in the future to upgrade to a second 2TB drive in a RAID-1 setup? Can this be done without formatting the original 2TB drive? *It looks like the £100 cashback offer is stopping end of Aug, making this system cost around £260 without HDDs. Are there any other brands that anyone would recommend for all-in-one hardware solutions.

  • ASP.Net Session Storage provider in 3-layer architecture

    - by Tedd Hansen
    I'm implementing a custom session storage provider in ASP.Net. We have a strict 3-layer architecture and therefore the session storage needs to go through the business layer. Presentation-Business-Database. The business layer is accessed through WPF. The database is MSSQL. What I need is (in order of preference): A commercial/free/open source product that solves this. The source code of a SqlSessionStateStore (custom session store) (not the ODBC-sample on MSDN) that I can modify to use a middle layer. I've tried looking at .Net source through Reflector, but the code is not usable. Note: I understand how to do this. I am looking for working samples, preferably that has been proven to work fine under heavy load. The ODBC sample on MSDN doesn't use the (new?) stored procs that the build in SqlSessionStateStore uses - I'd like to use these if possible (decreases traffic). Edit1: To answer Simons question on more info: ASP.Net Session()-object can be stored in either InProc, ASP.Net State Service or SQL-server. In a secure 3-layer model the presentation layer (web server) does not have direct/physical access to the database layer (SQL-server). And even without the physical limitations, from an architectural standpoint you may not want this. InProc and ASP.Net State Service does not support load balancing and doesn't have fault tolerance. Therefore the only option is to access SQL through webservice middle layer (business layer).

  • Pasted image hides behind text even when set to be inline

    - by John
    I copied an image from MSPaint and pasted it into a Word document I'm working on. For some reason the image hides behind the text even with the default "in line with text" setting. Trying other settings don't work as expected either. It does the same when I insert a picture from a file. Can anyone shed any light what would be causing this and how to fix it - I am guessing some formatting issue in the existing document?

  • Convert a CSV file to a XLS file on the linux command line?

    - by Rory
    I'm using Debian Linux and I want to convert a CSV file to an Excel XLS Spreadsheet file. The catdoc package includes the xls2csv command that converts from XLS to CSV. However it doesn't do the reverse. Since I just have a CSV file, I don't care about formatting or anything like that. I'm not worried if it only generates a very simple XLS file, and doesn't support the fancy new versions. Just so long as it's an XLS spreadsheet.

  • Python: why does this code take forever (infinite loop?)

    - by Rosarch
    I'm developing an app in Google App Engine. One of my methods is taking never completing, which makes me think it's caught in an infinite loop. I've stared at it, but can't figure it out. Disclaimer: I'm using http://code.google.com/p/gaeunitlink text to run my tests. Perhaps it's acting oddly? This is the problematic function: def _traverseForwards(course, c_levels): ''' Looks forwards in the dependency graph ''' result = {'nodes': [], 'arcs': []} if c_levels == 0: return result model_arc_tails_with_course = set(_getListArcTailsWithCourse(course)) q_arc_heads = DependencyArcHead.all() for model_arc_head in q_arc_heads: for model_arc_tail in model_arc_tails_with_course: if model_arc_tail.key() in model_arc_head.tails: result['nodes'].append(model_arc_head.sink) result['arcs'].append(_makeArc(course, model_arc_head.sink)) # rec_result = _traverseForwards(model_arc_head.sink, c_levels - 1) # _extendResult(result, rec_result) return result Originally, I thought it might be a recursion error, but I commented out the recursion and the problem persists. If this function is called with c_levels = 0, it runs fine. The models it references: class Course(db.Model): dept_code = db.StringProperty() number = db.IntegerProperty() title = db.StringProperty() raw_pre_reqs = db.StringProperty(multiline=True) original_description = db.StringProperty() def getPreReqs(self): return pickle.loads(str(self.raw_pre_reqs)) def __repr__(self): return "%s %s: %s" % (self.dept_code, self.number, self.title) class DependencyArcTail(db.Model): ''' A list of courses that is a pre-req for something else ''' courses = db.ListProperty(db.Key) def equals(self, arcTail): for this_course in self.courses: if not (this_course in arcTail.courses): return False for other_course in arcTail.courses: if not (other_course in self.courses): return False return True class DependencyArcHead(db.Model): ''' Maintains a course, and a list of tails with that course as their sink ''' sink = db.ReferenceProperty() tails = db.ListProperty(db.Key) Utility functions it references: def _makeArc(source, sink): return {'source': source, 'sink': sink} def _getListArcTailsWithCourse(course): ''' returns a LIST, not SET there may be duplicate entries ''' q_arc_heads = DependencyArcHead.all() result = [] for arc_head in q_arc_heads: for key_arc_tail in arc_head.tails: model_arc_tail = db.get(key_arc_tail) if course.key() in model_arc_tail.courses: result.append(model_arc_tail) return result Am I missing something pretty obvious here, or is GAEUnit acting up?

  • Hard drive corrupts when fiddling with partitions.

    - by Archagon
    I've had problems with my hard drive ever since I got it a year ago. For the most part, it works fine, but whenever I try to do anything with partitions, be it adding, deleting, or resizing, some of the data in my other partitions inevitably corrupts. I've tried formatting my entire drive, but to no avail. What's going on?

  • Bootable backup of a Mac without an HFS+ disk?

    - by marienbad
    How can I make a bootable backup of my Mac's internal hard drive to be restored using Disk Utility, without formatting my external destination drive as HFS+ (it's FAT32, of course)? Time Machine and SuperDuper both require that the volume where the backup is saved be HFS+ formatted. This looks helpful: http://developer.apple.com/macosx/backuponmacosx.html But it doesn't explain how to use FAT32 disk.

  • Starting a code library.

    - by Rob Stevenson-Leggett
    Hi, I've been meaning to start a library of reusable code snippets for a while and never seem to get round to it. I think my main problems are: Where to start. What structure should my library take? Should it be a compiled library (where appropriate or just classes I can drop into any project? Or a library project that can be included? In my experience, a built library will quickly become out of date and the source will get lost. So I'm leaning towards source libraries that I can export from SVN and include in any project. Intellectual property. I am employeed, so a lot of the code I write is not my IP. How can I ensure that I don't give my own IP away using it on projects in work and at home? I'm thinking the best way would be to licence my library with an open source licence and make sure I only add to it in my own time using my own equipment and therefore making sure that if I use it in a work project the same rules apply as if I was using a third party library. I write in many different languages and often would require two or more parts of this library. Should I look at implementing a few template projects and a core project for each of my chosen reusable components and languages? Has anyone else got this sort of library and how do you organise and update it?

  • jQuery.data() works in Mac OS WebKit, but not on iPhone OS?

    - by rpj
    I'm playing around with jQTouch for an iPhone OS app that I've been toying with off and on for a while. I wanted to try my hand building it as a web app so I started playing with jQTouch. For reference, here is the page+source (all my code is currently in index.html so you can just "View Source" to see it all): http://rpj.me/doughapp.com/wd/ Essentially, I'm trying to save pertinent JSON objects retrieved from Google Local into DOM objects using the data() method (in this example, obj is the Google Local object): $('#locPane').data('selected', obj); then later (in a different "pane"), retrieving that object to be used: $('#locPane').bind('pageAnimationEnd', function(e, inf) { var selobj = $(this).data('selected'); // use 'selobj' here ... } In Chromium and Safari on the desktop OS (Snow Leopard in my case), this works perfectly (try it out). However, the same code returns undefined for the call to $(this).data('selected') in the second snippet above. I've also tried $('#' + e.target.id).data('selected') and even the naive $('#locPane').data('selected'). All variants return undefined in the iPhone OS version of WebKit, but not on the desktop. Interestingly, the running this on Mobile Safari in the iPhone Simulator fails as well. If you look at the full source, you'll see that I even try to save this object into my global jQTouch object (named jqt in my code). This, too, fails on the mobile platform. Has anyone else ever ran into this? I'll admit to not being a web/javascript programmer by trade, so if I'm making an idiot's error please call me out on it. Thank you in advance for the help! -RPJ Update: I didn't make it clear in the original post, but I'm open to any workaround if it works consistently. Since I'm having trouble storing these objects in general, anything that allows me to keep them around is good enough for now. Thanks!

  • Two Objects created with the same Address in Flex

    - by James
    Hi, I have an issue in flex which is causing a bit of a headache! I am adding objects to an ArrayCollection but in doing so, another ArrayCollection is also picking up these changes even though there is no binding occurring. I can see from the debug that the two ACs have the same address but for the life of me can't figure out why. I have two Array Collections: model.index.rows //The main array collection model.index.holdRows //The array collection that imitates the above This phantom data binding occurs only for the first iteration in the loop and for all others it will just write it the once. The reason this is proving troublesome is that it creates duplicate entries in my datagrid. public override function handleMessage(message:IMessage):void { super.handleMessage(message); if (message is IndexResponse) { var response:IndexResponse = message as IndexResponse; model.index.rows.removeAll(); model.index.indexIsEmpty = response.nullIndex; if (model.index.indexIsEmpty !== true) { //Update the index model from the response. Note: each property of the row object will be shown in the UI as a column in the grid response.index.forEach(function(entry:EntryData, i:int, a:Array):void { var row:Object = { fileID: entry.fileID, dadName: entry.dadName }; entry.tags.forEach(function(tag:Tag, i:int, a:Array):void { row[tag.name] = tag.value; }); model.index.rows.addItem(row); }); if(model.index.indexForNetworkView == true){ model.index.holdRows.source = model.index.holdRows.source.concat(model.index.rows.source); model.index.indexCounter++; model.index.indexForNetworkView = false; controller.indexController.showNetwork(model.index.indexCounter); } model.index.rows.refresh(); controller.networkController.show(); } } Has anyone else who has encountered something simillar propose a solution?

  • WPF - Dynamically access a specific item of a collection in XAML

    - by Andy T
    Hi, I have a data source ('SampleAppearanceDefinitions'), which holds a single collection ('Definitions'). Each item in the collection has several properties, including Color, which is what I'm interested in here. I want, in XAML, to display the Color of a particular item in the collection as text. I can do this just fine using this code below... Text="{Binding Source={StaticResource SampleAppearanceDefinitions}, Path=Definitions[0].Color}" The only problem is, this requires me to hard-code the index of the item in the Definitions collection (I've used 0 in the example above). What I want to do in fact is to get that value from a property in my current DataContext ('AppearanceID'). One might imagine the correct code to look like this.... Text="{Binding Source={StaticResource SampleAppearanceDefinitions}, Path=Definitions[{Binding AppearanceID}].Color}" ...but of course, this is wrong. Can anyone tell me what the correct way to do this is? Is it possible in XAML only? It feels like it ought to be, but I can't work out or find how to do it. Any help would be greatly appreciated! Thanks! AT

  • How to get rid of large gaps in text in MS Word

    - by Kristin
    When formatting a document such as a resume, MS Word often inserts a large gap in the text--sometimes as much as half a page of blank space. When I try to delete the gap, moving the cursor from the continued text after the gap, it skips over the gap as if it's not even there, and deletes text from the previous point in the document before the gap. I can't "grab" the gap or highlight/delete the gap in any way. Ideas??

  • TFS: Choose which workspace to add a solution too.

    - by Patricker
    I have a solution which I developed in VS2008 and which I am trying to add to Source Control (TFS 2010, though the issue happened in TFS 2008 as well). I have several TFS workspaces on my computer and I have access to several Team Projects. When I right click the solution in my Solution Explorer and choose the "Add Solution to Source Control" option I am never given an option of choosing which Workspace or which Team Project to add the existing solution too. VS2008 then proceeds to add it to the same team project every time. I have tried selecting an alternate workspace/team project in every window where I can see an option for it but it always adds it back to the same one. I even tried changing the name of my new workspace so that alphabetically it was the first thinking that it might be somehow related to that... no luck. I then tried goign to the Change Source Control window where you can add/remove bindings on a solution/project but that window also defaults to the same Team Project as trying to add the solution directly does... Any help would be greatly appreciated with this, maybe I'm just missing something?

  • Silverlight Image Data Binding

    - by Alexander
    I am new to Silverlight, and have an issue with binding. I have a class ItemsManager, that has inside its scope another class Item. class ItemsManager { ... class Item : INotifyPropertyChanged { ... private BitmapImage bitmapSource; public BitmapImage BitmapSource { get { return bitmapSource; } set { bitmapSource = value; if(PropertyChanged != null )PropertyChanged("BitmapSource") } } } } I do the following in code to test binding: { ItemsManager.Instance.AddItem("123"); //Items manager started downloading item visual //part (in my case bitmap image png) Binding b = new Binding("Source"); b.Source = ItemsManager.Instance.GetItem("123").BitmapSource; b.BindsDirectlyToSource = true; Image img = new Image(); img.SetBinding(Image.SourceProperty, b); img.Width = (double)100.0; img.Height = (double)100.0; LayoutRoot.Children.Add(img); } Once image is loaded, image doesn't appear. Though, if I set directly after image has been loaded its source, it displays well. I also noticed that PropertyChanged("BitmapSource") never fires, because PropertyChanged is null, like Image never binded to it. I am looking forward to hearing from you!

  • Advice: Python Framework Server/Worker Queue management (not Website)

    - by Muppet Geoff
    I am looking for some advice/opinions of which Python Framework to use in an implementation of multiple 'Worker' PCs co-ordinated from a central Queue Manager. For completeness, the 'Worker' PCs will be running Audio Conversion routines (which I do not need advice on, and have standalone code that works). The Audio conversion takes a long time, and I need to co-ordinate an arbitrary number of the 'Workers' from a central location, handing them conversion tasks (such as where to get the source files, or where to ask for the job configuration) with them reporting back some additional info, such as the runtime of the converted audio etc. At present, I have a script that makes a webservice call to get the 'configuration' for a conversion task, based on source files located on the worker already (we manually copy the source files to the worker, and that triggers a conversion routine). I want to change this, so that we can distribute conversion tasks ("Oy you, process this: xxx") based on availability, and in an ideal world, based on pending tasks too. There is a chance that Workers can go offline mid-conversion (but this is not likely). All the workers are Windows based, the co-ordinator can be WIndows or Linux. I have (in my initial searches) come across the following - and I know that some are cross-dependent: Celery (with RabbitMQ) Twisted Django Using a framework, rather than home-brewing, seems to make more sense to me right now. I have a limited timeframe in which to develop this functional extension. An additional consideration would be using a Framework that is compatible with PyQT/PySide so that I can write a simple UI to display Queue status etc. I appreciate that the specifics above are a little vague, and I hope that someone can offer me a pointer or two. Again: I am looking for general advice on which Python framework to investigate further, for developing a Server/Worker 'Queue management' solution, for non-web activities (this is why DJango didn't seem the right fit).

  • Enterprise Platform in Python, Design Advice

    - by Jason Miesionczek
    I am starting the design of a somewhat large enterprise platform in Python, and was wondering if you guys can give me some advice as to how to organize the various components and which packages would help achieve the goals of scalability, maintainability, and reliability. The system is basically a service that collects data from various outside sources, with each outside source having its own separate application. These applications would poll a central database and get any requests that have been submitted to perform on the external source. There will be a main website and REST/SOAP API that should also have access to the central data service. My initial thought was to use Django for the web site, web service and data access layer (using its built-in ORM), and then the outside source applications can use the web service(s) to get the information they need to process the request and save the results. Using this method would allow me to have multiple instances of the service applications running on the same or different machines to balance out the load. Are there more elegant means of accomplishing this? i've heard of messaging systems such as MQ, would something like that be beneficial in this scenario? My other thought was to use a completely separate data service not based on Django, and use some kind of remoting or remote objects (in they exist in Python) to interact with the data model. The downside here would be with the website which would become much slower if it had to push all of its data requests through a second layer. I would love to hear what other developers have come up with to achieve these goals in the most flexible way possible.

  • How do I format a Uri when binding an Image in Silverlight?

    - by Scott
    I haven't been able to find an answer to this. I have a database that has image paths in it ("images/myimage.jpg"). These images exist on my asp.net site which is also where I host the SL. I want to bind these images to my ListBox control so that the image displays. I have read that since I have a string value, "images/myimage.jpg", that I need to convert it to a BitMap image. I have done this: the xaml: <Image Source="{Binding ImageFile, Converter={StaticResource ImageConverter}}"/> the ImageConverter class: public object Convert(object value, Type targetType, object parameter, CultureInfo culture) { try { Uri source= new Uri(value.ToString()); return new BitmapImage(source); } catch(Exception ex) { return new BitmapImage(); } } I get an error when creating the Uri, "The Format of the URI could not be determined". What am I doing wrong? If I create a Uri that looks like this: http://localhost:49723/images/myimage.jpg, it works just fine. Why doesn't just "images/myimage.jpg" work?

    I have a spreadsheet with several cells in one column. Each cell has identical conditional formatting: In 1 cell value equal to ='Y' In 2 cell value equal to ='N' In 3 cell value equal to ='?' What I would like to achieve is, if all 7 cells contain "Y" as the option then a separate cell will display "Yes", but if any of the cells contain "N" as the selection then the separate cell will display "NO". How can I achieve this?

  • What is the fastest way to type an en dash in Windows 7?

    - by Geoff Olynyk
    Simple question: What's the quickest way to get an en dash (–, Unicode U+2013 EN DASH) in Windows? Note that this question is for all programs, not just Microsoft Word. Even better if it can be copied to the clipboard as a pure Unicode character, with no formatting information (typeface, etc.) so that when I paste it into Word or Excel or other rich text editors, it doesn't carry its format with it.

  • SWT Browser Drag and Drop

    - by scottalas
    I'm trying to use drag-n-drop with an embedded SWT Browser, so that my application can drag hyperlinks from the Browser to another Control. I've been able to set up the destination to receive data from an external browser, but the internal does not seem to participate in the drag-n-drop. Any ideas? I would guess that I need something like a selection listener to track when something is grabbed in the browser, or some way to ask the browser what is currently selected, perhaps using javascript. My current setup of the Browser is simplistic, looking like this: browser = new Browser(top, SWT.NONE); // MOZILLA createDragSource(browser); // below // a selection listener never receives events: browser.addListener(SWT.Selection, new Listener() { @Override public void handleEvent(Event event) { System.out.println("Selection listener event"); } }); ... private void createDragSource(final Browser browser) { Transfer[] types = new Transfer[] { URLTransfer.getInstance(), HTMLTransfer.getInstance(), TextTransfer.getInstance(), ImageTransfer.getInstance(), }; int mode = DND.DROP_COPY | DND.DROP_LINK | DND.DROP_MOVE; DragSource dragSource = new DragSource(browser, mode); dragSource.setTransfer(types); dragSource.addDragListener(new DragSourceListener() { public void dragStart(DragSourceEvent event) { System.out.println("source.dragStart"); } public void dragSetData(DragSourceEvent event) { System.out.println("source.dragSetData"); // Is there a way to get the Browser's drag item here? } public void dragFinished(DragSourceEvent event) { System.out.println("source.dragFinished"); //do nothing } }); } Thanks for any help!

  • Update table using SSIS

    - by thursdaysgeek
    I am trying to update a field in a table with data from another table, based on a common key. If it were in straight SQL, it would be something like: Update EHSIT set e.IDMSObjID = s.IDMSObjID from EHSIT e, EHSIDMS s where e.SITENUM = s.SITE_CODE However, the two tables are not in the same database, so I'm trying to use SSIS to do the update. Oh, and the sitenum/site_code are varchar in one and nvarchar in the other, so I'll have to do a data conversion so they'll match. How do I do it? I have a data flow object, with the source as EHSIDMS and the destination as EHSIT. I have a data conversion to convert the unicode to non-unicode. But how do I update based on the match? I've tried with the destination, using a SQL Command as the Data Access mode, but it doesn't appear to have the source table. If I just map the field to be updated, how does it limit it based on fields matching? I'm about to export my source table to Excel or something, and then try inputting from there, although it seems that all that would get me would be to remove the data conversion step. Shouldn't there be an update data task or something? Is it one of those Data Flow transformation tasks, and I'm just not figuring out which it is?
