• Populate a combo box with one data tabel and save the choice in another.

  - by Scott Chamberlain

  I have two data tables in a data set for example lets say Servers: | Server | Ip | Users: | Username | Password | Server | and there is a foreign key on users that points to servers. How do I make a combo box that list all of the servers. Then how do I make the selected server in that combo box be saved in the data set in the Server column of the users table. EDIT -- I havent tested it yet but is this the right way? this.bsServers.DataMember = "Servers"; this.bsServers.DataSource = this.dataSet; this.bsUsers.DataMember = "FK_Users_Servers"; this.bsUsers.DataSource = this.bsServers; this.serverComboBox.DataBindings.Add(new System.Windows.Forms.Binding("SelectedValue", this.bsUsers, "Server", true)); this.serverComboBox.DataSource = this.bsServers; this.serverComboBox.DisplayMember = "Server"; this.serverComboBox.ValueMember = "Server";

• Is it possible to find the KNN for a node that is *IN* the KD-tree?

  - by Stephen

  Hi there, Trying to create a KNN search using a KD-tree. I can form the KD-tree fine (or at least, I believe I can!). My problem is that I am searching to find the closest 2 neighbours to every point in a list of points. So, is there a method to find the K nearest neighbours to a point using a KD tree even if the point is actually IN the tree, or do I need to construct a seperate KD tree for each point, leaving out the point that I wish to search for? My implementation language is C++, but I am more looking for either an algorithm or general help, thanks! Thanks, Stephen

• Pair programming tools that are not remote

  - by JonathanTech

  I am currently in a job where we practice serious pair programming on windows machines. We both have a set of keyboards, mice, and we have two monitors, which works well for switching who's the driver really easy, but there are some points in the session that I would like to start writing tests at the same time that my pair is writing implementation. I am wondering if there is any program that would allow me to have effectively two cursors and keyboard focuses on the same computer. If they don't exist then I am willing to experiment with my own solution, but I would like input as to how to best accomplish this. I am most familiar with .Net 3.5 technologies, but I also know Java and am willing to learn C++ to solve this problem. If I was creating the solution myself I would go down the road of being able to grab the input of one hardware device (i.e. a specific mouse that's installed) and prevent Windows from moving the pointer, and instead move my own programs pointer independently.

• Comparison of ASP.Net Reporting Solutions

  - by Brian MacKay

  This week my team spent way too much time trying to do simple things in reporting services, and I've decided to start evaluating other options. I know there are some good options out there now that aren't too expensive. I've heard that Telerik, ActiveReports, and a few others are widely used. I was hoping to get some first hand accounts regarding reporting tools that you've used. Specifically, I definitely want to hear your thoughts about: Pain points and gotchas you ran into. Ease of use for report design. It's a little bizarre to me that Access still seems to hold the throne in this area! What's your favorite tool? Anything I've missed that seems important to you. Thanks a lot!

• Having trouble with binding

  - by Tam

  I'm not sure if I'm misunderstanding the binding in Flex. I'm using Cairngorm framework. I have the following component with code like: [Bindable] var _model:LalModelLocator = LalModelLocator.getInstance(); .... <s:DataGroup dataProvider="{_model.friendsSearchResults}" includeIn="find" itemRenderer="com.lal.renderers.SingleFriendDisplayRenderer"> <s:layout> <s:TileLayout orientation="columns" requestedColumnCount="2" /> </s:layout> </s:DataGroup> in the model locator: [Bindable] public var friendsSearchResults:ArrayCollection = new ArrayCollection(); Inside the item renderer there is a button that calls a command and inside the command results there is a line like this: model.friendsSearchResults = friendsSearchResults; Putting break points and stepping through the code I confirmed that this like gets called and the friendsSearchResults gets updated. To my understanding if I update a bindable variable it should automatically re-render the s:DataGroup which has a dataProvider of that variable.

• Code Golf: Triforce

  - by chpwn

  This is inspired by/taken from this thread: http://www.allegro.cc/forums/thread/603383 The Problem Assume the user gives you a numeric input ranging from 1 to 7. Input should be taken from the console, arguments are less desirable. When the input is 1, print the following: *********** ********* ******* ***** *** * Values greater than one should generate multiples of the pattern, ending with the one above, but stacked symmetrically. For example, 3 should print the following: *********** *********** *********** ********* ********* ********* ******* ******* ******* ***** ***** ***** *** *** *** * * * *********** *********** ********* ********* ******* ******* ***** ***** *** *** * * *********** ********* ******* ***** *** * Bonus points if you print the reverse as well. *********** *********** ********* ********* ******* ******* ***** ***** *** *** * * *********** ********* ******* ***** *** * * *** ***** ******* ********* *********** * * *** *** ***** ***** ******* ******* ********* ********* *********** *********** Can we try and keep it to one answer per language, that we all improve on?

• Continents/Countries borders in PostGIS (Polygon vs Linestring)

  - by Joey

  Hello guys, I would like to insert the polygon containing Europe in my PostGIS database. I have the follwoing extremes points: NW = NorthWest Border(lat=82.7021697 lon=-28.0371000) NE = NorthEast Border(lat=82.7021697 lon=74.1357000) SE = SouthEast Border(lat=33.8978000 lon=74.1357000) SW = SouthWest Border(lat=33.8978000 lon=-28.0371000) Is the following a valid polygon: POLYGON((NWLon NWLat, NELon NELat, SELon SElat, SWLon SWLat, NWlon NWLat)) Is this a valid polygon? I do see some polygon with the follwing format POLYGON((), ()) ? When are they used? Why not a linestring? Any help will be apreciated? This is getting me really confused. Thanks

• WCF performance improvements

  - by Burt

  I am developing a WPF application that talks to a server via WCF services over the internet. After profiling the application I noticed a lot of time is being taking up by creating the appropriate WCF client proxy and making the call to the server. The code on the server is optimised and doesn't take any time to run yet I am still seeing a 1.5 second delay from when a service is invloked to it returning to the client. A few points to give a bit of background: I am using the ASP.Net membership for security I will eventually hook into the same server side code through a website I would eventually like to have offline support in the application I really need to nail the performance early though as if the app is taking a couple of seconds to come back it is too long for what I am trying to do. Can anyone suggest performance tips that will help me please?

• how to use Foreign key in L2E or EF?

  - by 5YrsLaterDBA

  I have a User table which has a PrivilegeId foreign key points to a Privilege table and is the primary key there. In Entity Framework, the VS will not generate a PrivilegeId variable under Users for you. It will generate a Privilege property and PrivilegeReference property for you instead. When I load a User, the Privilege property is null by default. That means EF does not load refered entity for you automatically. I think I may did something wrong? I cannot load Privilege separatedly because I have no info about the Privilege at that time. I guess EF should load the refered entities for me but I missed something. anybody can help me?

• Just quick: How do you call a mutator from within a constructor in the same class?

  - by Blockhead

  For a homework assignment the instructions state (within Undergrad class): You do NOT need to include a default constructor, but you must write a full parameterized constructor (it takes 4 arguments) -- this constructor calls the parent class parameterized constructor and the mutator for year level. Because Undergrad extends Student, then Student is my parent class, right? I just can't quite figure out how I'm to use my year level mutator (which is just the simplest of methods) to assign my "year" attribute. public void setYear(int inYear) { year = inYear; } public Student(String inName, String inID, int inCredits) { name = inName; id = inID; credits = inCredits; } public Undergrad(String inName, String inID, int inCredits,int inYear) { super(inName, inID, inCredits); year = inYear; } I keep missing assignments because I spend too much time on these small specific points of the homework so just asking for a little help. I swear it's the wording that throws me off on these assignments almost as often as just learning the material itself.

• Resizing screenshots/screen captures for inclusion in Beamer

  - by Stephen

  Sorry, this may or may not be a programming question directly, but I am trying to resize screenshots with Imagemagick and Gimp to include in a Beamer presentation, but it comes out even blurrier than the resizing done by LaTeX. For instance, in Beamer I might have a command to rescale the image \includegraphics[width=.5\textwidth]{fig.png}. Using something like \begin{frame} \message{width = \the\textwidth} \message{height = \the\textheight} \end{frame} I have gotten the \textwidth and \textheight parameters in points (345.69548, 261.92444). So I have a script (in Python) that sends a system call to Imagemagick: 'convert %s -resize %.6f@ resized_%s' % (f,a,f) where a is calculated as \textwidth*\textheight*0.5**2. When I then go back into my Beamer presentation and include the resized figure, \includegraphics{resized_fig.png}, the size looks approximately correct but it's super-blurry. I also tried resizing in Gimp (using the GUI) but no luck either... help? Thanks...

• replace file with hardlink to another file atomically

  - by Ben Clifford

  I have two directory entries, a and b. Before, a and b point to different inodes. Afterwards, I want b to point to the same inode as a does. I want this to be safe - by which I mean if I fail somewhere, b either points to its original inode or the a inode. most especially I don't want to end up with b disappearing. mv is atomic when overwriting. ln appears to not work when the destination already exists. so it looks like i can say: ln a tmp mv tmp b which in case of failure will leave a 'tmp' file around, which is undesirable but not a disaster. Is there a better way to do this? (what I'm actually trying to do is replace files that have identical content with a single inode containing that content, shared between all directory entries)

• Comparison of Hudson, CDash, CruisonControl, TeamCity for Continuous Integration / Builder

  - by Wernight

  I found most people talk about Hudson for simple and free continuous integration. Now personally I'm not fond of its interface which I find very messy, and I found almost no one talking about CDash -- I love CMake and CTest seem nice too. Could you give for each continuous integration server/builder/tester/dashboard a short description of its strong and weak decision points. Here is a list of those I've heard of, or used: Hudson CDash CruisonControl TeamCity Bamboo Environment: C++, C#, Python, PHP... can be various. PS: Preferably give one answer per tool or comment on it there is already one.

• CCSprite following a sequence of CGPoints

  - by pgb

  I'm developing a line drawing game, similar to Flight Control, Harbor Master, and others in the appstore, using Cocos2D. For this game, I need a CCSprite to follow a line that the user has drawn. I'm storing a sequence of CGPoint structs in an NSArray, based on the points I get in the touchesBegin and touchesMoved messages. I now have the problem of how to make my sprite follow them. I have a tick method, that is called at the framerate speed. In that tick method, based on the speed and current position of the sprite, I need to calculate its next position. Is there any standard way to achieve this? My current approach is calculate the line between the last "reference point" and the next one, and calculate the next point in that line. The problem I have is when the sprite "turns" (moves from one segment of the line to another). Any hint will be greatly appreciated.

• Visual Studio 2008 - The breakpoint cannot be hit

  - by Josh

  I know that many people have had this problem... but I am now having it and cannot solve the issue. VS 2008 is randomly giving me an error after working on a project for weeks. When I set a debug point, I get a warning: The breakpoint will not currently be hit. No symbols have been loaded for this document. I have re-built the solution with no debug points and re-tried. I have also tried to Load Symbols from path and that has not worked either... Can someone please help walk me through the necessary steps to getting my debug function working again. Thanks.

• svn merge - moved repository to a different server, and now getting 'has different repository root'

  - by HorusKol

  This is kind of similar to http://stackoverflow.com/questions/1601021/subversion-merge-has-different-repository-root-than - but appears to be a very different cause (especially as the answer for that question didn't resolve my problem). A while back, we swapped out the server where our SVN repositories are located - but we've been using an alias so that the old server name points to the new server. I've been getting in the habit where I will use the new server name wherever I checkout new working copies - but we having made changes to most of the current working copies as they are live websites. Until now, this hasn't been a problem - except that this morning I merged in some changes from my development branch to a working copy I have of the release version and I got the message "file has different repository root" and the merge stops dead. I know this is because I'm using the new server name when the development branch was updated via the old server name - but is there a simple way to fix this? Or if not a simple way - is there a well-documented way to fix this?

• MVS 2008 and C99

  - by yCalleecharan

  Hi, I read with interest the post "How universally is C99 supported ?". One of the comments therein points that Microsoft doesn't support C99. But the comment symbol // works with MVS 2008 and this symbol is in C99. I have two questions: To what extent MVS 2008 support C99? Is it ok in the same code to mix C89 and C99 syntax together? So if I write my code in C89 and then place a comment //. This means that I have mixed-coding. So what does the compiler do in such a case? Check my code first with c89 and then with C99 to accept that I use // for commenting? Thanks a lot...

• Matplotlib subplots_adjust hspace so titles and xlabels don't overlap ?

  - by Denis

  With say 3 rows of subplots in matplotlib, xlabels of one row can overlap the title of the next; one has to fiddle with pl.subplots_adjust( hspace ), annoying. Is there a recipe for hspace that prevents overlaps and works for any nrow ? """ matplotlib xlabels overlap titles ?

• How do you fix TSD02016 error in Database

  - by Keith Sirmons

  Howdy, I have a database I am using the Visual Studio 2010 Database Project tool vsdbcmd.exe to create a schema from. vsdbcmd /a:Import /dsp:Sql /model:"Database" /cs:"Server=SqlServer; Initial Catalog=DatabaseName; Integrated Security=SSPI;" The tool is reporting an error: Error TSD02016, Gen-259 (12,50) The column name is not valid. No table name was specified. How would I go about pinpointing where this error is originating? I have found one resource on the internet (http://social.msdn.microsoft.com....) that points to a possibility of a keyword used incorrectly, but the error messages are not the same. What is Gen-259? Thank you, Keith

• "Go To Definition" in Visual Studio only brings up the Metadata

  I am working in a Web Project in Visual Studio 2008. When I hit F12 (or right-click and select Go To Definition) Visual Studio is consistently going to the Meta data file instead of going to the source. Some Points: All the source code is C#, there is no VB.Net All the projects are in the same solution Yes, everything is a project reference (checked and double-checked) I have tried the Clean/Rebuild Solution approach (even to the point of clearing out the Temp directory, Temporary ASP.NET Files directory, etc). Has anyone else seen this behavior and/or know how to fix it?

• What are your thoughts on Raven DB?

  - by Ronnie Overby

  What are your thoughts on Raven DB? I see this below my title: The question you're asking appears subjective and is likely to be closed. Please don't do that. I think the question is legit because: Raven DB is brand-spanking-new. RDBMS's are probably the de facto for data persistence for .net developers, which Raven DB is not. Given these points, I would like to know your general opinions. Admittedly, the question is sort of broad. That is intentional, because I am trying to learn as much about it as possible, however here are some of my initial concerns and questions: What about using Raven DB for data storage in a shared web hosting environment, since Raven DB is interacted with through HTTP? Are there any areas that Raven DB is particularly well or not well suited for? How does it rank among alternatives, from a .net developer's perspective?

• clicking the debug button in Eclipse will not start debug mode

  - by iHorse

  i am running Eclipse 3.5.0 on a MacBook Pro using the Android SDK. i noticed that on this particular project i am working on i cant seem to actually enter debug mode. i click the little green bug icon in the tool bar and the app starts and runs. but if i switch over to the Debug Perspective i see no indication that it is running in debug mode. furthermore i can not hit any brake points that i have set. this makes debugging code a bit hard. Other projects that i am working on don't have this issue. any ideas on what i need to change in the project to get this to work?

• Using recursion to find paths in a 2D array

  - by rikkit

  Hi, I'm working on a project for my A level. It involves finding the maximum flow of a network, and I'm using javascript. I have a 2D array, with values in the array representing a distance between the two points. An example of the array: 0 2 2 0 0 0 1 2 0 0 0 2 0 0 0 0 I think I need to use a recursive technique to find a path; below is some pseudocode, assuming that the array is 4x4. a is (0,0), b is (3,3). function search(a,b) from a to b if element(i,j) != 0 then store value of element search(j,3) I was wondering if that was the right construction for a depth first search. Thanks for any help.
