• How can you connect to a password protected MS Access Database from a Spring JdbcTemplate?

  - by Tim Visher

  I need to connect to a password protected MS Access 2003 DB using the JDBC-ODBC bridge. I can't find out how to specify the password in the connect string, or even if that is the correct method of connecting. It would probably be relevant to mention that this is a Spring App which is accessing the database through a JdbcTemplate configured as a datasource bean in our application context file. Some relevant snippets: from application-context.xml <bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate"> <property name="dataSource" ref="legacyDataSource" /> </bean> <bean id="jobsheetLocation" class="java.lang.String"> <constructor-arg value="${jobsheet.location}"/> </bean> <bean id="legacyDataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="${jdbc.legacy.driverClassName}" /> <property name="url" value="${jdbc.legacy.url}"/> <property name="password" value="-------------" /> </bean> from our build properties jdbc.legacy.driverClassName=sun.jdbc.odbc.JdbcOdbcDriver jdbc.legacy.url=jdbc:odbc:Driver\={Microsoft Access Driver (*.mdb)};Dbq\=@LegacyDbPath@;DriverID\=22;READONLY\=true Any thoughts?

• How do I relocate assemblies from a deployment project without breaking application references?

  - by James

  Hi, I have recently refactored a lot of my applications existing code and I am now looking at tidying up the deployment side of things. The existing installer application installs everything in the application folder (with the exclusion of a couple of config files which are located in a sub folder). However, I have multiple applications which all use some common assemblies and my goal is to relocate a these particular assemblies to the "Common Files" folder in the program files directory. NB: I have read a lot about the GAC but I have no experience with it and also read a few horror stories, so trying to get a simple solution for the time being. I managed to get the assemblies installed into the Common Files folder, however, as a result (typical I.T.) I have broken my app! If I copy the assemblies back into the application folder it works fine so the problem is obviously to do with how my app is referencing the assemblies. To get the installer to install the assemblies into the Common Files folder I just updated the Folder property of each assembly in the Detected Dependencies list. My thoughts were when I did that the installer would somehow update my application to tell it to look in that folder for them but that doens't appear to be the case. What exactly am I doing wrong here?

• Help with Hashmaps in Java

  - by Crystal

  I'm not sure how I use get() to get my information. Looking at my book, they pass the key to get(). I thought that get() returns the object associated with that key looking at the documentation. But I must be doing something wrong here.... Any thoughts? import java.util.*; public class OrganizeThis { /** Add a person to the organizer @param p A person object */ public void add(Person p) { staff.put(p, p.getEmail()); System.out.println("Person " + p + "added"); } /** * Find the person stored in the organizer with the email address. * Note, each person will have a unique email address. * * @param email The person email address you are looking for. * */ public Person findByEmail(String email) { Person aPerson = staff.get(email); return aPerson; } private Map<Person, String> staff = new HashMap<Person, String>(); public static void main(String[] args) { OrganizeThis testObj = new OrganizeThis(); Person person1 = new Person("J", "W", "111-222-3333", "[email protected]"); testObj.add(person1); System.out.println(testObj.findByEmail("[email protected]")); } }

• Global hotkey capture in VB.net

  - by ggonsalv

  I want to have my app which is minimized to capture data selected in another app's window when the hot key is pressed. My app definitely doesn't have the focus. Additionally when the hot key is pressed I want to present a fading popup (Outlook style) so my app never gets focus. At a minimum I want to capture the Window name, Process ID and the selected data. The app which has focus is not my application? I know one option is to sniff the Clipboard, but are there any other solutions. This is to audit the rate of data-entry in to another system of which I have no control. It is a mainframe emulation client program(attachmate). The plan is complete data entry in Application X. Select a certain section of the screen in App X which is proof of data entry (transaction ID). Press the Magic Hotkey, which then 'sends' the selection to my App. From System.environment or system.Threading I can find the Windows logon. Similiarly I can also capture the time. All the data will be logged to SQL. Once Complete show Outlook style pop up saying the data entry has been logged. Any thoughts.

• Implementing scroll view that is much larger than the screen view with random images

  - by pulegium

  What I'm trying to do is to implement something like the fruit machine scroll view. Basically I have a sequence of images (randomly generated on the fly) and I want to allow the users to scroll through this line. There can fit approx 10 images on the screen, but the line is virtually unlimited. My question is what would be the best approach in implementing this? So far I've thought of having a UIImageView going across the screen (with width equal to the sum of 10 images) and the image associated with it would be a combination of 12 or so images, with two images falling out of the visible area, this would allow for smooth scrolling. If the user scrolls further, then I would reconstruct the image associated with the view so the new images are appended and the old one's are discarded. This image reconstruction business sounds bit complicated, so I was wondering if there's a more logical way to implement this. There's one more thing, I want to have two lines crossing each other with images, bit like conveyor belts crossing. If that makes any sense... Bit like below: V1 V2 H1 H2 H3 H4 H5 V4 V5 So if the vertical belt is moved it'd be like: V2 H3 H1 H2 V4 H4 H5 V5 V6 H1-H5, V1-V6 being automatically generated images. I'm not asking for the implementation code, just the thoughts on the principles how to implement this. Thanks!! :)

• Giving another object a NSManagedObject

  - by Wayfarer

  Alright, so I'm running into an issue with my code. What I have done is subclassed UIButton so I can give it some more infomormation that pertain to my code. I have been able to create the buttons and they work great. Capiche. However, one of the things I want my subclass to hold is a reference to a NSMangedObject. I have this code in my header file: @interface ButtonSubclass : UIButton { NSManagedObjectContext *context; NSManagedObject *player; } @property (nonatomic, retain) NSManagedObject *player; @property (nonatomic, retain) NSManagedObjectContext *context; - (id)initWithFrame:(CGRect)frame andTitle:(NSString*)title; //- (void)setPlayer:(NSManagedObject *)aPlayer; @end As you can see, it has a instance variable to the NSMangedobject I want it to hold (as well as the Context). But for the life of me, I can't get it to hold that NSManagedObject. I run both the @synthesize methods in the Implementation file. @synthesize context; @synthesize player; So I'm not sure what I'm doing wrong. This is how I create my button: ButtonSubclass *playerButton = [[ButtonSubclass alloc] initWithFrame:frame andTitle:@"20"]; //works playerButton.context = self.context; //works playerButton.player = [players objectAtIndex:i]; //FAILS And I have initilaized the players array earlier, where I get the objects. Another weird thing is that when it gets to this spot in the code, the app crashes (woot) and the the console output stops. It doesn't give me any error, and notification at all that the app has crashed. It just... stops. So I don't even know what the error is that is crashing the code, besides it has to do with that line up there setting the "player" variable. Thoughts and ideas? I'd love your wisdom!

• How to setup relationships in contact Database

  - by Walt

  I am currently embarking on a new venture to learn PHP and MySQL. I have done some simple databases in the past using Access, but this one is to be a web-centric database for tracking a myriad of data including contacts and project information. I will need to link the various tables in various relationships, and I am not sure the best way to do that. Since I am just starting out with PHP/MySQL I am researching online sources for learning as much as possible. If anyone has recommendations on books or websites, I would appreciate it. In setting up my tables, one major area that I am concerned with is contacts. I will have a variety of contacts that include: employees, clients, vendors, subcontractors, etc.. and a single contact can be multiple types and each type would have various additional fields that pertain to them. My thought was to have one contacts table that links to other tables for the various contact types. I'm not sure which field type or setup of table options are best... Thoughts? This scenario will likely play out in other areas of the database as well for projects and products. Any pointers/direction would be appreciated. WES

• Storing arbitrary data in HTML

  - by Rob Colburn

  What is the best way to embed data in html elements for later use? As an example, let's say we have jQuery returning some JSON from the server, and we want to dump that datat out to the user as paragraphs. However, we want to be able to attach meta-data to these elements, so we can events for these later. The way I tend to handle this, is with some ugly prefixing function handle_response(data) { var html = ''; for (var i in data) { html += '<p id="prefix_' + data[i].id + '">' + data[i].message + '</p>'; } jQuery('#log').html(html).find('p').click(function(){ alert('The ID is: ' + $(this).attr('id').substr(7)); }); } Alternatively, one can build a Form in the paragraph, and store your meta-data there. But, that often feels like overkill. This has been asked before in different ways, but I do not feel it's been answered well: http://stackoverflow.com/questions/432174/how-to-store-arbitrary-data-for-some-html-tags http://stackoverflow.com/questions/209428/non-standard-attributes-on-html-tags-good-thing-bad-thing-your-thoughts

• Guid Primary /Foreign Key dilemma SQL Server

  - by Xience

  Hi guys, I am faced with the dilemma of changing my primary keys from int identities to Guid. I'll put my problem straight up. It's a typical Retail management app, with POS and back office functionality. Has about 100 tables. The database synchronizes with other databases and receives/ sends new data. Most tables don't have frequent inserts, updates or select statements executing on them. However, some do have frequent inserts and selects on them, eg. products and orders tables. Some tables have upto 4 foreign keys in them. If i changed my primary keys from 'int' to 'Guid', would there be a performance issue when inserting or querying data from tables that have many foreign keys. I know people have said that indexes will be fragmented and 16 bytes is an issue. Space wouldn't be an issue in my case and apparently index fragmentation can also be taken care of using 'NEWSEQUENTIALID()' function. Can someone tell me, from there experience, if Guid will be problematic in tables with many foreign keys. I'll be much appreciative of your thoughts on it...

• SQL Server 2008 - db mail issue

  - by Chris

  Hello. I have two instances of SQL Server 2008. One was upgraded from SQL Server 2000 and one was a clean, new install. SQL Mail operates perfectly on both instances. DB Mail operates perfectly on the newly installed instance. On the upgraded instance, DB Mail does not send any mail. Of course, I am not positive that the fact this instance is upgraded has anything to do with the issue, but it might. The configuration of my db mail profile and account looks identical to my functioning instance. In the configuration of the 'alerts' tab in the SQL Agent properties i have tried selecting both DB Mail and SQL Mail to no avail. Both instances use the same SMTP server with the same authentication (domain with db engine account). All messages sent via sp_send_db mail and those sent via the 'test email' option are visible in the sysmail_allitems queue and remain there as 'unsent'. The send_status eventually changes to 'failed'. The only messages in the sysmail_event_log are 'mail queue stopped by login domain\myuser', 'mail queue started by login domain/myuser' and 'activiation successful.'. selecting from the externalmailqueue has the same number of rows as sysmail_allitems. i have tried bouncing the agent, the entire instance and moving the other functioning instance to the other node in the cluster. any thoughts? thx.

• C# creating a Class, having objects as member variables? I think the objects are garbage collecte

  - by Bryan

  So I have a class that has the following member variables. I have get and set functions for every piece of data in this class. public class NavigationMesh { public Vector3 node; int weight; bool isWall; bool hasTreasure; public NavigationMesh(int x, int y, int z, bool setWall, bool setTreasure) { //default constructor //Console.WriteLine(x + " " + y + " " + z); node = new Vector3(x, y, z); //Console.WriteLine(node.X + " " + node.Y + " " + node.Z); isWall = setWall; hasTreasure = setTreasure; weight = 1; }// end constructor public float getX() { Console.WriteLine(node.X); return node.X; } public float getY() { Console.WriteLine(node.Y); return node.Y; } public float getZ() { Console.WriteLine(node.Z); return node.Z; } public bool getWall() { return isWall; } public void setWall(bool item) { isWall = item; } public bool getTreasure() { return hasTreasure; } public void setTreasure(bool item) { hasTreasure = item; } public int getWeight() { return weight; } }// end class In another class, I have a 2-Dim array that looks like this NavigationMesh[,] mesh; mesh = new NavigationMesh[502,502]; I use a double for loop to assign this, my problem is I cannot get the data I need out of the Vector3 node object after I create this object in my array with my "getters". I've tried making the Vector3 a static variable, however I think it refers to the last instance of the object. How do I keep all of these object in memory? I think there being garbage collected. Any thoughts?

• Function should return float, but it gets messed up!

  - by Andre

  Hi guys, I'm going crazy here. I have a function that should return a float number: - (float) getHue:(UIColor *)original { NSLog(@"getHue"); const CGFloat *componentColors = CGColorGetComponents(original.CGColor); float red = componentColors[0]; float green = componentColors[1]; float blue = componentColors[2]; float h = 0.0f; float maxChannel = fmax(red, fmax(green, blue)); float minChannel = fmin(red, fmin(green, blue)); if (maxChannel == minChannel) h = 0.0f; else if (maxChannel == red) h = 0.166667f * (green - blue) / (maxChannel - minChannel) + 0.000000f; else if (maxChannel == green) h = 0.166667f * (blue - red) / (maxChannel - minChannel) + 0.333333f; else if (maxChannel == blue) h = 0.166667f * (red - green) / (maxChannel - minChannel) + 0.666667f; else h = 0.0f; if (h < 0.0f) h += 1.0f; NSLog(@"getHue results: %f", h); return h; } The NSLog will trace it correctly (i.e: 0.005), but the actual return value of the function is NULL. I've tried getting that value in so many ways and it never works. float originalHue = [self getHue:original]; results in a building error, as it says: "incompatible types in initialization" float *originalHue = [self getHue:original]; results in a null return. I've tried other ways, but it never actually gets the value properly. Any thoughts? Cheers guys, Andre

• Why rails app is redirecting unexpectedly instead of matching the route?

  - by ruevaughn

  I asked this question earlier and thought it was fixed, but it's not. Previous question here My problem is I am trying to set my routes so that when I type in localhost:3000/sites/admin It should redirect to localhost:3000/en/sites/admin here is my routes.rb file scope ":locale", locale: /#{I18n.available_locales.join("|")}/ do get "log_out" => "sessions#destroy", as: "log_out" get "log_in" => "sessions#new", as: "log_in" resources :sites, except: [:new, :edit, :index, :show, :update, :destroy, :create] do collection do get :home get :about_us get :faq get :discounts get :services get :contact_us get :admin get :posts end end resources :users resources :abouts resources :sessions resources :coupons resources :monthly_posts resources :reviews resources :categories do collection { post :sort } resources :children, :controller => :categories, :only => [:index, :new, :create, :new_subcategory] end resources :products do member do put :move_up put :move_down end end resources :faqs do collection { post :sort } end root :to => 'sites#home' match "/savesort" => 'sites#savesort' end match '', to: redirect("/#{I18n.default_locale}") match '*path', to: redirect("/#{I18n.default_locale}/%{path}") But as of right now, it redirects to /en/en/en/en/en/en/en/en/en/en/sites/admin (adds en until browser complains). Any thoughts why it keeps adding /en?

• Microsoft Training in .NET

  - by JD

  Hey guys, A quick question about training. My company are offering to put me through a 5 day course in .NET programming with C#, on the proviso that I work for them for a minimum 12 month period immediately after the training has been completed. IF I don't work for them for 12months I will be expected to pay them back teh cost of the training, minus the amount of months which I have stayed at the company (e.g. stay 6 months and only pay back half). The course will be $3,300 AUD - and will have no qualifications. I have been programming in C# for about 6 months, and in PHP for about 10 years - so I am getting the hang of .NET slowly but surely. Is it worth doing this? Or would I be best advised to learn from reading the MS books from Amazon for $40 and then sitting the 2 exams to get MS certified off my own back? The company are not willing to pay for my certification as well as 'they are not training me to get certified' and hence more employable... Thoughts? How do other companies deal with training? And stop people from taking off after becoming certified?

• Using include() to load different page content acts differently locally vs hosted

  - by hookedonwinter

  I have a live site that includes different php files depending on what page the user is trying to access. The header and footer are the same, but in the file, if the user requests filename1.php vs filename2.php, a different php is loaded into the content of the page. Basic CMS stuff. On the live site, it works fine. I just set up a local dev environment, and it doesn't work. The file that is supposed to load into the middle of the page instead is the only file loaded. I'm not saying this well. Here's an example: How it works live: <html> <head> Stuff </head> <body> More stuff <? include( 'some_file.php' ); ?> </body> </html> How it works locally: <? include( 'some_file.php' ); ?> Just that file loads, no other content. Any thoughts on why that one page is loading, but not the surrounding content? If I'm not explaining this well, please let me know.

• Ideas Related to Subset Sum with 2,3 and more integers

  - by rolandbishop

  I've been struggling with this problem just like everyone else and I'm quite sure there has been more than enough posts to explain this problem. However in terms of understanding it fully, I wanted to share my thoughts and get more efficient solutions from all the great people in here related to Subset Sum problem. I've searched it over the Internet and there is actually a lot sources but I'm really willing to re-implement an algorithm or finding my own in order to understand fully. The key thing I'm struggling with is the efficiency considering the set size will be large. (I do not have a limit, just conceptually large). The two phases I'm trying to implement ideas on is finding two numbers that are equal to given integer T, finding three numbers and eventually K numbers. Some ideas I've though; For the two integer part I'm thing basically sorting the array O(nlogn) and for each element in the array searching for its negative value. (i.e if the array element is 3 searching for -3). Maybe a hash table inclusion could be better, providing a O(1) indexing the element? For the three or more integers I've found an amazing blog post;http://www.skorks.com/2011/02/algorithms-a-dropbox-challenge-and-dynamic-programming/. However even the author itself states that it is not applicable for large numbers. So I was for 2 and 3 and more integers what ideas could be applied for the subset problem. I'm struggling with setting up a dynamic programming method that will be efficient for the large inputs as well.

• Is there a way to implement Caliburn-like co-routines in VB.NET since there's no yield keyword

  - by Miroslav Popovic

  Note that I'm aware of other yield in vb.net questions here on SO. I'm playing around with Caliburn lately. Bunch of great stuff there, including co-routines implementation. Most of the work I'm doing is C# based, but now I'm also creating an architecture guideline for a VB.NET only shop, based on Rob's small MVVM framework. Everything looks very well except using co-routines from VB. Since VB 10 is used, we can try something like Bill McCarthy's suggestion: Public Function Lines(ByVal rdr as TextReader) As IEnumerable(Of String) Return New GenericIterator(Of String) (Function(ByRef nextItem As String) As Boolean nextItem = rdr.ReadLine Return nextItem IsNot Nothing End Function) End Function I'm just failing to comprehend how a little more complex co-routine method like the one below (taken from Rob's GameLibrary) could be written in VB: public IEnumerable<IResult> ExecuteSearch() { var search = new SearchGames { SearchText = SearchText }.AsResult(); yield return Show.Busy(); yield return search; var resultCount = search.Response.Count(); if (resultCount == 0) SearchResults = _noResults.WithTitle(SearchText); else if (resultCount == 1 && search.Response.First().Title == SearchText) { var getGame = new GetGame { Id = search.Response.First().Id }.AsResult(); yield return getGame; yield return Show.Screen<ExploreGameViewModel>() .Configured(x => x.WithGame(getGame.Response)); } else SearchResults = _results.With(search.Response); yield return Show.NotBusy(); } Any idea how to achieve that, or any thoughts on using Caliburn co-routines in VB?

• Javascript function using "this = " gives "Invalid left-hand side in assignment"

  - by Brian M. Hunt

  I am trying to get a Javascript object to use the "this" assignments of another objects' constructor, as well as assume all that objects' prototype functions. Here's an example of what I'm attempting to accomplish: /* The base - contains assignments to 'this', and prototype functions */ function ObjX(a,b) { this.$a = a, $b = b; } ObjX.prototype.getB() { return this.$b; } function ObjY(a,b,c) { // here's what I'm thinking should work: this = ObjX(a, b * 12); /* and by 'work' I mean ObjY should have the following properties: * ObjY.$a == a, ObjY.$b == b * 12, * and ObjY.getB() == ObjX.prototype.getB() * ... unfortunately I get the error: * Uncaught ReferenceError: Invalid left-hand side in assignment */ this.$c = c; // just to further distinguish ObjY from ObjX. } I'd be grateful for your thoughts on how to have ObjY subsume ObjX's assignments to 'this' (i.e. not have to repeat all the this.$* = * assignments in ObjY's constructor) and have ObjY assume ObjX.prototype. My first thought is to try the following: function ObjY(a,b,c) { this.prototype = new ObjX(a,b*12); } Ideally I'd like to learn how to do this in a prototypal way (i.e. not have to use any of those 'classic' OOP substitutes like Base2). It may be noteworthy that ObjY will be anonymous (e.g. factory['ObjX'] = function(a,b,c) { this = ObjX(a,b*12); ... }) -- if I've the terminology right. Thank you.

• Django Development Environment Setup Questions

  - by Ross Peoples

  Hello, I'm trying to set up a good development environment for a Django project that I will be working on from two different physical locations. I have two Mac machines, one at home and one at work that I do most of my development on. I currently host a Ubuntu virtual machine on one of the machines to host the Django environemnt, install DropBox on it, and edit source code from my Mac. When I save the code file, the changes get synced over DropBox to the Ubuntu VM and the Django development server automatically restarts because of the change. This method has worked well in the past, but I am starting to use DropBox for a lot of other things now and don't want all of that to be downloaded on every virtual machine I use. Plus, I want to start using Eclipse + PyDev to be able to debug code and have code completion. Currently, I use TextEdit which is great, but doesn't support debugging or completion. So what are my options? I thought about setting up a Parallels VM on a thumb drive that has my entire environment on it (Eclipse included), but that has its own problems. Any other thoughts?

• UIButton and UIControlEventState issue

  - by Typeoneerror

  I'm having a very specific "bug" in my iPhone application. I'm setting two images for the highlighted and normal states of a button. It works as expected when you "press" and then "touch up" at a slow pace, but if you click/tap it quickly, there's a noticeable flicker between states. Is this a known bug or am I setting the states incorrectly? Here's the code that creates the buttons: UIImage *normalImage = [[UIImage imageNamed:@"btn-small.png"] stretchableImageWithLeftCapWidth:10.0f topCapHeight:0.0f]; UIImage *highlightedImage = [[UIImage imageNamed:@"btn-small-down.png"] stretchableImageWithLeftCapWidth:10.0f topCapHeight:0.0f]; [self setBackgroundColor:[UIColor clearColor]]; [self setBackgroundImage:normalImage forState:UIControlStateNormal]; [self setBackgroundImage:highlightedImage forState:UIControlStateDisabled]; [self setBackgroundImage:highlightedImage forState:UIControlStateHighlighted]; [self setAdjustsImageWhenDisabled:FALSE]; [self setAdjustsImageWhenHighlighted:FALSE]; When a button is tapped it simply disables itself and enables the other button: - (IBAction)aboutButtonTouched:(id)sender { aboutButton.enabled = FALSE; rulesButton.enabled = TRUE; } - (IBAction)rulesButtonTouched:(id)sender { rulesButton.enabled = FALSE; aboutButton.enabled = TRUE; } Any thoughts on this quick-click flicker?

• Default update detailViewController, HELP.

  - by DrBeak1

  I've created an app that allows users to add information (from an addViewController), which is then displayed in a UITableView on the rootViewController. When the user taps the tableViewCell the detailViewController then displays, you guessed it, more details regarding the inputted user information. What I'm trying to accomplish is to setup an editViewController that will allow users to edit information they've already submitted. Currently, I'm trying to auto-populate the editViewController with the information that was previously submitted by the user (after which they can press save and update the info). However, I'm getting stuck trying to perform this auto-populating and I'm not sure this is even the best route to accomplish this. Here is the edit method that is called to load the editViewController from the detailViewController. -(IBAction)editDetails:(id)sender { editViewController *evc = [[editViewController alloc] initWithNibName:@"editViewController" bundle:nil]; rootViewController *rvc = [[rootViewController alloc] init]; UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:evc]; [[self navigationController] presentModalViewController:navigationController animated:YES]; ///For Style NSInteger styleCount = [[rvc scoreTypeArray] count]; NSInteger styleRows = [rvc.scoreTypeArray objectAtIndex:indexPath.row]; ///HERE I GET AN ERROR MESSAGE SAYING THAT indexPath IS NOT DEFINED ///For Date NSInteger count = [[rvc dateArray] count]; NSInteger rows = [[rvc indexPath] row]; ///AND HERE I GET A WARNING MESSAGE SAYING rootViewController MAY NOT RESPOND TO INDEX PATH, AND OF COURSE IT DOESN'T WORK [[evc dateField] setText:[NSString stringWithFormat:@"%@", [[evc dateArray] objectAtIndex:(count-1-rows)]]]; [[evc styleField] setText:[NSString stringWithFormat:@"%@", [[rvc scoresArray] objectAtIndex:(styleCount-1-styleRows)]]]; [navigationController release]; [evc release]; [rvc release];} So here I'm trying to load the information from a saved array that is declared in my rootViewController. Any thoughts any body? Please and thank you : )

  Hi Gang, I am trying to make a Visual Studio AddIn that removes unused references from the projects in the current solution (I know this can be done, Resharper does it, but my client doesn't want to pay for 300 licences). Anyhoo, I use DTE to loop through the projects, compile their assemblies, then reflect over those assemblies to get their referenced assemblies and cross-examine the .csproj file. Problem: since the .dll/.exe I loaded up with Reflection doesn't unload until the app domian unloads, it is now locked and the projects can't be built again because VS tries to re-create the files (all standard stuff). I have tried creating temporary files, then reflecting over them...no worky, still have locked original files (I totally don’t understand that BTW). Now I am now going down the path of creating a temporary AppDomain to load the files into and then destroy. I am having problems loading the files though: The way I understand AddDomain.Load is that I should create and send a byte array of the assembly to it. I do that: FileStream fs = new FileStream(assemblyFile, FileMode.Open); byte[] assemblyFileBuffer = new byte[(int)fs.Length]; fs.Read(assemblyFileBuffer, 0, assemblyFileBuffer.Length); fs.Close(); AppDomainSetup domainSetup = new AppDomainSetup(); domainSetup.ApplicationBase = assemblyFileInfo.Directory.FullName; AppDomain tempAppDomain = AppDomain.CreateDomain("TempAppDomain", null, domainSetup); Assembly projectAssembly = tempAppDomain.Load(assemblyFileBuffer); The last line throws an exception: "Could not load file or assembly 'WindowsFormsApplication1, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.":"WindowsFormsApplication3, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null"}" Any help or thoughts would be greatly appreciated. My head is lopsided from beating it against the wall... Thanks, Dan

• What are Code Smells? What is the best way to correct them?

  - by Rob Cooper

  OK, so I know what a code smell is, and the Wikipedia Article is pretty clear in its definition: In computer programming, code smell is any symptom in the source code of a computer program that indicates something may be wrong. It generally indicates that the code should be refactored or the overall design should be reexamined. The term appears to have been coined by Kent Beck on WardsWiki. Usage of the term increased after it was featured in Refactoring. Improving the Design of Existing Code. I know it also provides a list of common code smells. But I thought it would be great if we could get clear list of not only what code smells there are, but also how to correct them. Some Rules Now, this is going to be a little subjective in that there are differences to languages, programming style etc. So lets lay down some ground rules: ** ONE SMELL PER ANSWER PLEASE! & ADVISE ON HOW TO CORRECT! ** See this answer for a good display of what this thread should be! DO NOT downmod if a smell doesn't apply to your language or development methodology We are all different. DO NOT just quickly smash in as many as you can think of Think about the smells you want to list and get a good idea down on how to work around. DO downmod answers that just look rushed For example "dupe code - remove dupe code". Let's makes it useful (e.g. Duplicate Code - Refactor into separate methods or even classes, use these links for help on these common.. etc. etc.). DO upmod answers that you would add yourself If you wish to expand, then answer with your thoughts linking to the original answer (if it's detailed) or comment if its a minor point. DO format your answers! Help others to be able to read it, use code snippets, headings and markup to make key points stand out!
