  • How to handle 30k files in a project which requires them?

    - by Jeremiah
    Visual Studio 2010 RC - Silverlight Application We have a library of images that we need to have access to. They are given to us from a vendor (through an installer) and they are not in a database, they are files in a folder (a very large monster of a folder). We do not control when the images change, so the vendor needs to be able to override them individually. We get updates frequently enough from this vendor to state that these images change "randomly" and without our (programmer) knowledge. The problem: I don't want 30K images in SVN. Heck, I don't even want to imagine them in my Solution. However, our application requires them in order to run properly. So, our build/staging servers need access to these images (we have two build servers). The Question: How would you handle it when your application will not work as specified without access to each of 30k images and you don't control when those images change? I'm do not want to have a crazy large SVN repository. Because I don't know when any of these images change, I really don't want them in my solution (definitely do not want a large solution, either). I also don't want a bunch of manual steps to do every time these images change. Our mantra, up to this point, has always been, any developer could download from SVN, compile and run our app. These images are going to kill that mantra. I'm tempted to make a WCF service that will return images if they exist and a dummy image if they don't. This way all dev boxes will return a dummy image and our build/staging/production boxes will return real images (ones that actually have the vendor's image installer installed on). This has to be a solved problem. What have other people done to handle these types of problems? I'm open to suggestions.

  • Spring.net customer namespace parser

    - by ListenToRick
    I have a customer parser which looks like this: [NamespaceParser( Namespace = "http://mysite/schema/cache", SchemaLocationAssemblyHint = typeof(CacheNamespaceParser ), SchemaLocation = "/cache.xsd" ) ] public class CacheNamespaceParser : NamespaceParserSupport { public override void Init() { RegisterObjectDefinitionParser("cache", new CacheParser ()); } } public class CacheParser : AbstractSimpleObjectDefinitionParser { protected override Type GetObjectType(XmlElement element) { return typeof(CacheDefinition); } protected override void DoParse(XmlElement element, ObjectDefinitionBuilder builder) { } protected override bool ShouldGenerateIdAsFallback { get { return true; } } } in the web config i have the following configuration.... <spring> <parsers> <parser type="Spring.Data.Config.DatabaseNamespaceParser, Spring.Data"/> <parser type="App.Web.CacheNamespaceParser, WebApp" /> </parsers> When I run the project I get the following error: An error occurred creating the configuration section handler for spring/parsers: Invalid resource name. Name has to be in 'assembly:<assemblyName>/<namespace>/<resourceName>' format. I put a break point in the CacheNamespaceParser init method and it is called. If I remove from the web config all is well! Any ideas whats wrong

  • Java extends classes - Share the extended class fields within the super class.

    - by Bastan
    Straight to the point... I have a class public class P_Gen{ protected String s; protected Object oP_Gen; public P_Gen(String str){ s = str; oP_Gen = new Myclass(this); } } Extended class: public class P extends P_Gen{ protected Object oP; public P(String str){ oP = new aClass(str); super(str); } } MyClass: public class MyClass{ protected Object oMC; public MyClass(P extendedObject){ oMc = oP.getSomething(); } } I came to realize that MyClass can only be instantiated with (P_Gen thisObject) as opposed to (P extendedObject). The situation is that I have code generated a bunch of classes like P_Gen. For each of them I have generated a class P which would contains my P specific custom methods and fields. When I'll regenerate my code in the future, P would not be overwritten as P_Gen would. ** So what happened in my case???!!!... I realized that MyClass would beneficiate from the info stored in P in addition to only P_Gen. Would that possible? I know it's not JAVA "realistic" since another class that extends P_Gen might not have the same fields... BY DESIGN, P_Gen will not be extended by anything but P.... And that's where it kinda make sens. :-) at least in other programming language ;-) In other programming language, it seems like P_Gen.this === P.this, in other word, "this" becomes a combination of P and P_Gen. Is there a way to achieve this knowing that P_Gen won't be extended by anything than P?

  • Performance of stored proc when updating columns selectively based on parameters?

    - by kprobst
    I'm trying to figure out if this is relatively well-performing T-SQL (this is SQL Server 2008). I need to create a stored procedure that updates a table. The proc accepts as many parameters as there are columns in the table, and with the exception of the PK column, they all default to NULL. The body of the procedure looks like this: CREATE PROCEDURE proc_repo_update @object_id bigint ,@object_name varchar(50) = NULL ,@object_type char(2) = NULL ,@object_weight int = NULL ,@owner_id int = NULL -- ...etc AS BEGIN update object_repo set object_name = ISNULL(@object_name, object_name) ,object_type = ISNULL(@object_type, object_type) ,object_weight = ISNULL(@object_weight, object_weight) ,owner_id = ISNULL(@owner_id, owner_id) -- ...etc where object_id = @object_id return @@ROWCOUNT END So basically: Update a column only if its corresponding parameter was provided, and leave the rest alone. This works well enough, but as the ISNULL call will return the value of the column if the received parameter was null, will SQL Server optimize this somehow? This might be a performance bottleneck on the application where the table might be updated heavily (insertion will be uncommon so the performance there is not a problem). So I'm trying to figure out what's the best way to do this. Is there a way to condition the column expressions with something like CASE WHEN or something? The table will be indexed up the wazoo as well for read performance. Is this the best approach? My alternative at this point is to create the UPDATE expression in code (e.g. inline SQL) and execute it against the server. This would solve my doubts about performance, but I'd rather leave this in a stored proc if possible.

  • mySQL select and group by values

    - by Foo
    I'd like to count and group rows by specific values. This seems fairly simple, but I can't seem to do it. I have a table set up similar to this: Table: Ratings id pID uID rating 1 1 2 7 2 1 7 7 3 1 5 4 4 1 1 1 id is the primary key, piD and uID are foreign-keys. Rating contains values between 1 and 10, and only between 1 and 10. I want to run some statistics and count the number of ratings with a certain value. In the example above, two have left a rating of 7. So I wrote the following query: SELECT COUNT(*) AS 'count' , 'rating' FROM 'ratings' WHERE pID= '1' GROUP BY `rating` ORDER BY `rating` Which yields the nice result as: count ratings 1 1 1 4 2 7 I'd like to get the mySQL query to include values between 1 and 10 as well. For example: Desired Result count ratings 1 1 0 2 0 3 1 4 0 5 0 6 2 7 0 8 0 9 0 10 Unfortunately, I'm relatively new to SQL and I've been reading through everything I could get my hands on for the past hour, but I can't get it to work. I've been leaning along the lines of a some type of JOIN. If anyone can point me in the right direction, it'd be appreciated. Thanks.

  • Are Thread.stop and friends ever safe in Java?

    - by Stephen C
    The stop(), suspend(), and resume() in java.lang.Thread are deprecated because they are unsafe. The Sun recommended work around is to use Thread.interrupt(), but that approach doesn't work in all cases. For example, if you are call a library method that doesn't explicitly or implicitly check the interrupted flag, you have no choice but to wait for the call to finish. So, I'm wondering if it is possible to characterize situations where it is (provably) safe to call stop() on a Thread. For example, would it be safe to stop() a thread that did nothing but call find(...) or match(...) on a java.util.regex.Matcher? (If there are any Sun engineers reading this ... a definitive answer would be really appreciated.) EDIT: Answers that simply restate the mantra that you should not call stop() because it is deprecated, unsafe, whatever are missing the point of this question. I know that that it is genuinely unsafe in the majority of cases, and that if there is a viable alternative you should always use that instead. This question is about the subset cases where it is safe. Specifically, what is that subset?

  • Is it possible to load an entire SQL Server CE database into RAM?

    - by DanM
    I'm using LinqToSql to query a small SQL Server CE database. I've noticed that any operations involving sub-properties are disappointingly slow. For example, if I have a Customer table that is referenced by an Order table via a foreign key, LinqToSql will automatically create an EntitySet<Order> property. This is a nice convenience, allowing me to do things like Customer.Order.Where(o => o.ProductName = "Stopwatch"), but for some reason, SQL Server CE hangs up pretty bad when I try to do stuff like this. One of my queries, which isn't really that complicated takes 3-4 seconds to complete. I can get the speed up to acceptable, even fast, if I just grab the two tables individually and convert them to List<Customer> and List<Order>, then join then manually with my own query, but this is throwing out a lot of the appeal of LinqToSql. So, I'm wondering if I can somehow get the whole database into RAM and just query that way, then occasionally save it. Is this possible? How? If not, is there anything else I can do to boost the performance? Note: My database in its initial state is about 250K and I don't expect it to grow to more than 1-2Mb. So, loading the data into RAM certainly wouldn't be a problem from a memory point of view.

  • Getting a particular menu item from MainMenu

    - by Garry
    I have a nib (winA.xib) that contains a window. My app delegate contains an NSWindowController subclass called WinAController. WinAController has a property (NSMenu *mainMenu) that I want to point to the MainMenu. I have set it after I instantiate WinAController with this code: WinAController = [[WinAController alloc] initWithWindowNibName:@"WinA"]; WinAController.mainMenu = [NSApp mainMenu]; I have a menu item underneath the "Window" top-level menu item on MainMenu that invokes the [WinAController showWindow] method and displays WinA. I want to toggle the on/off state of this menu item depending on whether WinA is visible or not. WinAController also has another property (NSMenuItem *myMenuItem). How can I get a reference to a sub menu of the "Window" top-level menu item. The title of sub menu item I want to get is "Command". I have tried this: if (mainMenu != nil) { myMenuItem = [mainMenu itemAtIndex:[mainMenu indexOfItemWithTitle:@"Command"]]; } But it doesn't seem to work. Where am I going wrong? Thanks,

  • UIView scaled to thumbprint, what about subviews?

    - by Parad0x13
    I have a UIImageView that I create progmatically right? Works like a charm when I initWithImage and set the parameters for scaling to UIViewContentModeScaleToFill. I can scale all day long and create many different smaller 'thumbprint' sized versions of the UIImageView at whim, HOWEVER when I add subviews to said UIImageView and then try to scale the happy new parent the child subview does not scale! I looked around and found that I should enable the setAutoresizingSubviews boolean of the parentView to true (Which I did) and then call: ChildView.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth; Which I also did... now when I scale the parent view the child also scales but crazy wacked out like and goes all over the place (Not a very good way of putting it) but my point is that I assumed the child would scale proportionally to the parent and stay in the same place (Which it doesn't) My question is how do I set up my code so that when I scale my parent view by 1/4 or w/e to make a thumbprint of the view the children subviews that the parent view owns will scale accordingly and allow the 1/4 sized thumbprint to look just like the full sized view (Just smaller).

  • Add file in ANT build (Tomcat server)

    - by Shaded
    Hey everyone, I have an ANT build that I need to setup so on deployment of the .war a certain file will be placed in a specific location. Currently my ant builds the war as follows... <target name="war" depends="jar"> <war destfile="${deploy}/file.war" webxml="${web-inf}/web.xml"> <fileset dir="${WebRoot}"> <include name="**/*.vm" /> <include name="**/*.js" /> <include name="**/*.jsp" /> <include name="**/*.html" /> <include name="**/*.css" /> <include name="**/*.gif" /> <include name="**/*.jpg" /> <include name="**/*.png" /> <include name="**/*.tld" /> <include name="**/applicationContext*.xml" /> <include name="**/jpivot/**" /> <include name="**/wcf/**" /> <include name="**/platform/**" /> <include name="**/Reports/**" /> </fileset> <lib dir="${web-inf.lib}" /> </war> </target> The file I need is called Scriptlet.class and it needs to be in WebRoot/WEB-INF/classes/ I've tried several things to get this to work and have yet to find one that works... if anyone can point me in the right direction I'd appreciate it!

  • How to pass variables to slot methods in QT?

    - by Neko
    Hi. I'm making a little chat messenger program, which needs a list of chat channels the user has joined. To represent this list graphically, I have made a list of QPushButtons, which all represent a different channel. These buttons are made with the following method, and that's where my problem kicks in: void Messenger::addToActivePanels(std::string& channel) { activePanelsContents = this->findChild<QWidget *>(QString("activePanelsContents")); pushButton = new QPushButton(activePanelsContents); pushButton->setObjectName("pushButton"); pushButton->setGeometry(QRect(0, 0, 60, 60)); pushButton->setText(""); pushButton->setToolTip(QString(channel.c_str())); pushButton->setCheckable(true); pushButton->setChecked(false); connect(pushButton, SIGNAL(clicked()), this, SLOT(switchTab(channel))); } (activePanelContents is a QWidget that holds the list.) The point is that each button should call the switchTab(string& tabname) method when clicked, including the specific channel's name as variable. This implementation doesn't work though, and I haven't been able to find out how to properly do this, even after reading several pages on it on the internet. Can anybody please tell me how to do this? It'd be greatly appreciated, as always. :)

  • How does this Bookmarklet allow you to stay signed into this site?

    - by Abs
    Hello all, I have come across Evernote's bookmarklet and was wondering how this worked. You can just drag it to your bookmark and go to any webpage, click that bookmarklet and it will first ask you to login in. All this I have done already and know how it works. The bit that I don't understand is that when you log in they authenticate you and allow you to submit stuff (in this case, a site url etc). When you are done the bookmarklet which placed a small overlay on the page you are viewing disappears. When you go to a new tab and use the bookmarklet again you are still logged in! How? I can see they are using an iFrame when their bookmarklet loads the overlay onto the page - but do they set cookies or something? If so, is this secure? Anyone can change the values? Or are they using some sort of private/public key system Btw, I would like to replicate this Bookmarklet using PHP/Javascript(JQuery maybe). I would appreciate if anyone can help me understand how they do this or point me to relevant tutorials. Thanks all for any help.

  • Log session and session changes of a asp.net web user

    - by Johan Wikström
    This is going to be a quite broad question, and any suggestions, examples, links are very welcome! I'm looking for a good way to log my users session, and actions on the site up to a certain point. The site in question is a site for doing bookings. The users start with doing a search, doing a few steps of data gathering and selections and end up with a booking. So what I need to implement is some kind of logging of the current session variables at each step the user takes. And perhaps some other valid information. Logging should preferably be done to the a database. At the end i would like to associate all these session with a booking reference. The goal is to later if something goes wrong with the booking or we need to investigate a situation have all information we need. I understand log4net is a popular choice for logging, and used it a bit myself for simple purposes, but can not find any good examples regarding my situation. This should be a common situation, i'm curious how others do it.

  • a simple program that counts and sums digits. How can I make it work?

    - by user1710386
    So I've to write a simple program(that loops) where you can enter an int and it spews out the number count and the sum of the numbers. Since I am such a tard when it comes to programming, I just scavanged the code online and tried to piece it together. I guess the sum block screws with n, but I am not really sure. Anyway, I would really appreciate it if somebody could point out mistakes and show me how can I make it work. #include <iostream> using namespace std; int main() { while(1) { int i,p,n,sum=0; //sum block cout<<"enter an int: "; cin>>n; { while(n!=0) { p=n % 10; sum+=p; n=n/10; } cout<<"int digit sum: "<<sum <<endl; } { int count = 0; while(n) { n /= 10; ++count; } cout <<"number of digits: " << count << '\n';} } }

  • Combine Arbitrary number of polygons together

    - by Jakobud
    I have an arbitrary number of polygons (hexes in this case) that are arranged randomly, but they are all touching another hex. Each individual hex has 6 x,y vertices. The vertex's are known for all the hexes. Can anyone point me in the direction of an algorithm that will combine all the hexes into a single polygon? Essentially I'm just looking for a function that spits out an array of vertex locations that are ordered in a way that when drawing lines from one to the next, it forms the polygon. This is my method so far: Create array of all the vertices for all the hexes. Determine the number of times a vertex occurs in the array If vertex is in the array 3+ times, delete the vertices from the array. If vertex is in the array 2 times, delete one of them. The next step is tricky though. I'm using canvas to draw out these polygons, which essentially involves drawing a line from one vertex to the next. So the order of the vertices in the final array is important. It can't be sorted arbitrarily. Also, I'm not looking for a "convex hull" algorithm, as that would not draw the polygon correctly. Are there any functions out there that do something like this? Am I on the right track or is there a better more efficient way?

  • how to seamlessly integrate subversion and git?

    - by mattv
    I'm looking for tips on how to seamlessly integrate subversion and git, for deploying web sites by a small team of web developers. We each have our own development versions of our sites on our local machines. We also have dev, staging, and live servers. As our team has grown, we haven't updated our revision control and deployment strategies accordingly. We had all been checking into the trunk of a shared Subversion repository. Both the dev & staging servers ran from a checkout of the trunk, so updating them involved running "svn update" while the live server ran as an export from trunk which required an "svn export" to get the latest code. In either case, we would often update just certain files by updating or exporting just those files or directories. That worked okay when there was just one or two developers. However, a big downside was that we couldn't point to an individual tag that represented what was currently on live at any given time. In keeping with corporate policy, we'd like to continue to use Subversion to store what we're now calling our "production branch," which will be what goes onto staging and live. However, we would like to use Git on our local and development sites. We especially like the idea of easier merges and being able to "cherry pick" updates that need to go live. We had initially planned on using git-svn, but it doesn't seem to work well in a shared environment such as our dev or staging servers. Anyone else doing something like this? What's the best way to make it work? Or are we making it more difficult than it should be?

  • Changing pointer of self

    - by rob5408
    I have an object that I alloc/init like normal just to get a instance. Later in my application I want to load state from disk for that object. I figure I could unarchive my class (which conforms to NSCoding) and just swap where my instance points to. To this end I use this code... NSString* pathForDataFile = [self pathForDataFile]; if([[NSFileManager defaultManager] fileExistsAtPath:pathForDataFile] == YES) { NSLog(@"Save file exists"); NSData *data = [[NSMutableData alloc] initWithContentsOfFile:pathForDataFile]; NSKeyedUnarchiver *unarchiver = [[NSKeyedUnarchiver alloc] initForReadingWithData:data]; [data release]; Person *tempPerson = [unarchiver decodeObjectForKey:@"Person"]; [unarchiver finishDecoding]; [unarchiver release]; if (tempPerson) { [self release]; self = [tempPerson retain]; } } Now when I sprinkled some NSLogs throughout my application I noticed self.person: <Person: 0x3d01a10> (After I create the object with alloc/init) self: <Person: 0x3d01a10> (At the start of this method) tempPerson: <Person: 0x3b1b880> (When I create the tempPerson) self: <Person: 0x3b1b880> (after i point self to the location of the tempPerson) self.person: <Person: 0x3d01a10> (After the method back in the main program) What am I missing?

  • Stop SQL returning the same result twice in a JOIN

    - by nbs189
    I have joined together several tables to get data i want but since I am new to SQL i can't figure out how to stop data being returned more than once. her's the SQL statement; SELECT T.url, T.ID, S.status, S.ID, E.action, E.ID, E.timestamp FROM tracks T, status S, events E WHERE S.ID AND T.ID = E.ID ORDER BY E.timestamp DESC The data that is returned is something like this; +----------------------------------------------------------------+ | URL | ID | Status | ID | action | ID | timestamp | +----------------------------------------------------------------+ | T.1 | 4 | hello | 4 | has uploaded a track | 4 | time | | T.2 | 3 | bye | 3 | has some news | 3 | time | | t.1 | 4 | more | 4 | has some news | 4 | time | +----------------------------------------------------------------+ That's a very basic example but does outline what happens. If you look at the third row the URL is repeated when there is a different status. This is what I want to happen; +-------------------------------------------------------+ | URL or Status | ID | action | timestamp | +-------------------------------------------------------+ | T.1 | 4 | has uploaded a track | time | | hello | 3 | has some news | time | | bye | 4 | has some news | time | +-------------------------------------------------------+ Please notice that the the url (in this case the mock one is T.1) is shown when the action is has uploaded a track. This is very important. The action in the events table is inserted on trigger of a status or track insert. If a new track is inserted the action is 'has uploaded a track' and you guess what it is for a status. The ID and timestamp is also inserted into the events table at this point. Note: There are more tables that go into the query, 3 more in fact, but I have left them out for simplicity.

  • Do I lose the benefits of macro recording if I develop Excel apps in Visual Studio?

    - by DanM
    I've written lots of Excel macros in the past using the following development process: Record a macro. Open the VBA editor. Edit the macro. I'm now experimenting with a Visual Studio 2008 "Excel 2007 Add-In" project (C#), and I'm wondering if I will have to give up this development process. Questions: I know I can still record macros using Excel, but is there any way to access the resulting code in Visual Studio? Or do I just have to copy and paste then C#-ize it? What happens with my "Personal Macro Workbook"? Can I use the macros I have stored in there within C#? Or is there some way to convert them to C#? If there is some support for opening and editing VBA macros in Visual Studio, can you provide a very brief summary of how it works or point me to a good reference? Do you have any other tips for transitioning from writing macros in VBA using Excel's built-in editor to writing them in C# with Visual Studio?

  • Grails - Where to store properties related to domains

    - by GalmWing
    This is something I have been struggling about for some time now. The thing is: I have many (20 or so) static arrays of values. I say static because that is how I'm actually storing them, as static arrays inside some domains. For example, if I have a list of known websites, I do: class Website { ... static websites = ["web1", "web2" ...] } But I do this just while developing, because I can easily change the arrays if needed, but what I'm going to do when the application is ready for deployment? In my project it is very probable that, at some point, these arrays of values change. I've been researching on that matter, one can store application properties inside an external .properties file, but it will be impossible to store an array, even futile, because if some array gets an additional value, the application can't recognize it until the name of the new property is added where needed. Another approach is to store this information in the database, but for some reason it seems like a waste to add 20 or more tables that will have just two rows, an id and a name. And the last option, as far as I know, would be an XML, but I'm not very experienced with those. It seems groovy has a way of creating and reading XML files relatively easy, but I don't know how difficult would be to modify an XML whose layout is predefined in the application. Needless to say that storing them in the config.groovy is not an option since any change will require to recompile. I haven't come across some "standard" (maybe a best practice?) way of dealing with these. So the questions is: Where to store these arrays?

  • Memory optimization while downloading

    - by lboregard
    hello all i have the following piece of code, that im looking forward to optimize, since i'm consuming gobs of memory this routine is heavily used first optimization would be to move the stringbuilder construction out of the download routine and make it a field of the class, then i would clear it inside the routine can you please suggest any other optimization or point me in the direction of some resources that could help me with this (web articles, books, etc). i'm thinking about replacing the stringbuilder by a fixed (much larger) size buffer ... or perhaps create a larger sized stringbuilder thanks in advance. StreamWriter _writer; StreamReader _reader; public string Download(string msgId) { _writer.WriteLine("BODY <" + msgId + ">"); string response = _reader.ReadLine(); if (!response.StartsWith("222")) return null; bool done = false; StringBuilder body = new StringBuilder(256* 1024); do { response = _reader.ReadLine(); if (OnProgress != null) OnProgress(response.Length); if (response == ".") { done = true; } else { if (response.StartsWith("..")) response = response.Remove(0, 1); body.Append(response); body.Append("\r\n"); } } while (!done); return body.ToString(); }

The idea is the prospective student visits my website, sees a class they want to take, clicks the thumbnail so first read a descriptive article about the class, at which point they can schedule the class for the time, day, and date of their choosing between the hours of 5am to 9pm, 365 days a year. As soon as the student has inputed the time, day and date of the class they want, they would go to a check out page to purchase the class time. The student would then be sent an email confirmation along with the exact location, the class name, and the time and date they selected. I was thinking of using Dwolla for the check out page because Dwolla offers either no fee or 25 cents per payment transaction, but I'm not sure I can hook up to them easily enough. My blog site is not finished by a longshot. I still have to actually input all of the class thumbnail images along with descriptions, but if you need to see what the page looks like the web address is http://www.myalexlogic.com Google blogger allows for third party code to be added within movable gadgets.

  • Evaluating creation of GUI via file vs coding

    - by nevets1219
    I'm working on a utility that will be used to test the project I'm currently working on. What the utility will do is allow user to provide various inputs and it will sends out requests and provide the response as output. However, at this point the exact format (which input is required and what is optional) has yet to be fleshed out. In addition, coding in Swing is somewhat repetitive since the overall work is simple though this should be the safest route to go as I have more or less full control and every component can be tweaked as I want. I'm considering using a configuration file that's in XML to describe the GUI (at least one part of it) and then coding the event handling part (in addition to validation, etc). The GUI itself shouldn't be too complicated. For each type of request to make there's a tab for the request and within each tab are various inputs. There seems to be quite a few questions about this already but I'm not asking for a 3rd party library to do this. I'm looking to do this myself, since I don't think it'll be too overly complicated (hopefully). My main consideration for using this is re-usability (later on, for other projects) and for simplifying the GUI work. My question is: are there other pros/cons that I'm overlooking? Is it worth the (unknown) time to do this? I've built GUI in VB.NET and with Flex3 before.
