• Windows 7: Loop through Taskbar items

  - by balint

  Hi, I'm trying to build a small utility for myself only to hide labels of running programs with windows visible in the taskbar where the label holds no information (for example "iTunes", "Microsoft SQL Server Mngmt Studio", "~cmd.exe") but keep windows like Windows Explorer and Visual Studio and MSN ungroupped, with labels (to know which folders you are currently listing, which projects are open, and who are you chatting with by name). I'm trying to loop through all windows in the taskbar on windows 7, but without any luck. I found some samples for XP's taskbar reorders, they no longer usable. I've checked the samples in WindowsAPICodePack for Windows 7 Taskbar manipulation, but it only lets me access my processes' windows.

• Best practices or tools for installing a SQL Server database

  - by Maestro1024

  Best practices or tools for installing a SQL Server database I have a SQL Server database designed with the SQL Server GUI database editor/Visual Studio. What is the best way to "install" that database on other systems. Said another way how should I ship this thing? I know I can save the scripts and set the primary/foreign keys with T-SQL but I suspect their is something better. I guess you could have people restore from backup but that does not seem very professional. What other choices are there and what are the pluses and minuses?

• C# going nuts when I declare variables with the same name as the ones in a lambda

  - by Rubys

  I have the following code (generates a quadratic function given the a, b, and c) Func<double, double, double, Func<double, double>> funcGenerator = (a, b, c) => f => f * f * a + b * f + c; Up until now, lovely. But then, if i try to declare a variable named a, b, c or f, visual studio pops a "A local variable named 'f' could not be declared at this scope because it would give a different meaning to 'f' which is used in a child scope." Basically, this fails, and I have no idea why, because a child scope doesn't even make any sense. Func funcGenerator = (a, b, c) = f = f * f * a + b * f + c; var f = 3; // Fails var d = 3; // Fine What's going on here?

• Why the "mutable default argument fix" syntax is so ugly, asks python newbie

  - by Cawas

  Now following my series of "python newbie questions" and based on another question. Go to http://python.net/~goodger/projects/pycon/2007/idiomatic/handout.html#other-languages-have-variables and scroll down to "Default Parameter Values". There you can find the following: def bad_append(new_item, a_list=[]): a_list.append(new_item) return a_list def good_append(new_item, a_list=None): if a_list is None: a_list = [] a_list.append(new_item) return a_list So, question here is: why is the "good" syntax over a known issue ugly like that in a programming language that promotes "elegant syntax" and "easy-to-use"? Why not just something in the definition itself, that the "argument" name is attached to a "localized" mutable object like: def better_append(new_item, a_list=[].local): a_list.append(new_item) return a_list I'm sure there would be a better way to do this syntax, but I'm also almost positive there's a good reason to why it hasn't been done. So, anyone happens to know why?

• Function Object in Java .

  - by Tony

  I wanna implement a javascript like method in java , is this possible ? Say , I have a Person class : public class Person { private String name ; private int age ; // constructor ,accessors are omitted } And a list with Person objects: Person p1 = new Person("Jenny",20); Person p2 = new Person("Kate",22); List<Person> pList = Arrays.asList(new Person[] {p1,p2}); I wanna implement a method like this: modList(pList,new Operation (Person p) { incrementAge(Person p) { p.setAge(p.getAge() + 1)}; }); modList receives two params , one is a list , the other is the "Function object", it loops the list ,and apply this function to every element in the list. In functional programming language,this is easy , I don't know how java do this? Maybe could be done through dynamic proxy, does that have a performance trade off?

• Help with Event-Based Components

  - by Joel in Gö

  I have started to look at Event-Based Components (EBCs), a programming method currently being explored by Ralf Wesphal in Germany, in particular. This is a really interesting and promising way to architect a software solution, and gets close to the age-old idea of being able to stick software components together like Lego :) A good starting point is the Channel 9 video here, and there is a fair bit of discussion in German at the Google Group on EBCs. I am however looking for more concrete examples - while the ideas look great, I am finding it hard to translate them into real code for anything more than a trivial project. Does anyone know of any good code examples (in C# preferably), or any more good sites where EBCs are discussed?

• Is SEO knowledge important for web developers?

  - by splattne

  Looking for some SEO (Search engine optimization) questions on Stackoverflow, I saw ambivalent reactions to these questions. Some were closed as "not programming related" or were downvoted, others were answered and got upvoted. It seems that many developers think SEO was something "dirty" or belonged in the realm of spam. IMHO designing for search engines and practising SEO techniques adds important value to the final product like, for example, a good user interface. Should SEO really be left to specialized non-programmers? Shouldn't web developers have profound SEO knowledge? Or is it okay to apply SEO as a post-development process?

• How do I draw an ellipse with arbitrary orientation pixel by pixel?

  - by amc

  Hi, I have to draw an ellipse of arbitrary size and orientation pixel by pixel. It seems pretty easy to draw an ellipse whose major and minor axes align with the x and y axes, but rotating the ellipse by an arbitrary angle seems trickier. Initially I though it might work to draw the unrotated ellipse and apply a rotation matrix to each point, but it seems as though that could cause errors do to rounding, and I need rather high precision. Is my suspicion about this method correct? How could I accomplish this task more precisely? I'm programming in C++ (although that shouldn't really matter since this is a more algorithm-oriented question).

• Debugging JavaScript in Internet Explorer

  - by Erik W

  I am working on a relatively complex JavaScript-driven website. It runs great in all browsers except Internet Explorer. I am getting this very curious error: "A Runtime Error has occurred. Do you wish to Debug? Line: 93,865,600. Error: Expected ';'" The issue is, I don't have 93 million lines of code, and clicking "Yes" doesn't attach to Visual Studio like it normally does. I can click on 'No' and the website continues to run fine, but if a user doesn't have JavaScript debugging disabled, I don't want them to see this meaningless error. Suggestions/Tools/Plugins to get to the bottom of this? And yeah, I learned my lesson, switch over and check my project in Internet Explorer more often... Thanks,

• 3 hash functions to best hash sliding window strings for a bloom filter with minimum collisions

  - by Duaa

  Hi all: I need 3 hash functions to hash strings of a sliding window moving over a text, to be used later to search within a bloom vector. I'm using C# in my programming I read something about rolling hash functions and cyclic polynomials, they are used for sliding window applications. But really, I did not find any codes, they are just descriptions So please, if anyone have any idea about 3 best C# hash functions to use with sliding window strings of fixed size (5-char), that consume less time and have minimum number of collisions, either they are rolling hash functions or others, please help me with some C# codes or links to hash functions names Duaa

• In using Samsung acclerometer

  - by cheesebunz

  Hi everyone , i have this sample code i want to use. I'm not sure where to place it. I'm using Visual studio 2008 , windows mobile 6 sdk. I wish to test the accelerometer but i'm not sure where i should code it. The start is e.g. form1. Do i create new existing item new program.cs a new C# file and do this(as of below)? #include "smiAccelerometer.h" SmiAccelerometerVector accel; // get the acceleration vector containing X, Y, Z components if (SmiAccelerometerGetVector(&accel) == SMI_SUCCESS) { // Successfully got acceleration. // Use accel.x, accel.y and accel.z in your application } else { // failed to get the acceleration }

• Is there a way to log when a particular memory location gets written and by which function?

  - by rusbi

  I'm having a bug in my c++ program which happens very rarely but crashes my program. It's seems I have some buffer overflow problem or something similar. I find that these types of bug are most difficult to find. My program always crashes because of the same corrupted memory location. I'm wondering if there is some debugging tool which could detect when a particular memory location get written to and logs the function which does it. I'm using VLD (visual leak detector) for my memory leak hunting and it works great. It substitutes the original mallocs which its own and logs every allocation. I was wondering if there is something similar for memory? I know that something like that would cripple a program, but it could be really helpful.

• COM port - how to identify a device (.net/c#)

  - by argh

  Hi, I'm programming for Windows CE and I need to connect to a scanner. There is no problem - I know that it is on port COM0, but if I plug in another device earlier it gets another COM port... to get all com ports the easy way is: SerialPort.GetPortNames() But I don't know how to identify a device? Is there any standard way? I can't 'ping' it since there is one device that only sends data... it spams data all the time... and I don't know how to 'ping' a device...

• How to use NSTableView's selectedRowIndexes?

  - by Jakub Lédl

  Hi guys, I'm just learning some basic programming in Objective C and Cocoa. I'm trying to get some data from NSTableView. Based on what I read in one tutorial, I wrote this: NSArray * items = [[itemsTableView selectedRowEnumerator] allObjects]; But then I learned that selectedRowEnumerator was deprecated already in 10.3 Panther and that I should use selectedRowIndexes. The problem is, I didn't find how to actually use the returned NSIndexSet to achieve the same result as with code written above. So, If anyone could give me a tip, I would be very grateful. Thanks.

• .NET Reflector and getters/setters issue

  - by Humberto

  I'm using an up-to-date .NET Reflector to disassemble an internal legacy app whose source code is almost impossible to recover. I need to find the cause of a nasty bug, and then possibly patch it. Reflector did a good job as usual in the re-creation of the project's structure, but soon I discovered that every property call was left "expanded" to its get_() and set_() method signatures, rendering the source code impossible to compile. A quick Visual Studio "Search/Replace" with regex solved these cases, but it's awkward. Is there a way to make Reflector behave correctly?

• Which C# 4.0 Book would you purchase, and why?

  - by Jeremy

  I'm currently looking at purchasing a few C# 4.0 books, namely: Essential C# 4.0 by Mark Michaelis or C# 4.0 Unleashed by Bart De Smet. I am aware that both books are yet to be released, but would you consider purchasing either of these books, or would you recommend another? Thanks for your time. Clarification: I'm not a .net Ninja, but I do have 8+ years experience with the framework & related languages. So I'm generally looking for in-depth books. I also train/instruct the rest of my organisation generally 6 - 12 months after each .net release. Each of the developers I train has the same or more .net experience then myself. Once again thank you all for your time. Update: Thank you everyone for your responses. I've decided to purchase both books along with Visual C# 2010 Recipes: A Problem-Solution Approach, as suggested by Waleed Al Balooshi.

• Delphi: How to diagnose sluggish UI?

  - by Ian Boyd

  i have a form, which you can pretend is laid out like Windows Explorer: panel on the left splitter client panel +------------+#+-----------------------+ | |#| | | |#| | | |#| | | |#| | | Left |#| Client | | |#| | | |#| | | |#| | | |#| | | |#| | +------------+#+-----------------------+ ^ | +----splitter The the left and client area panels are each rich with controls. The problem is that using the splitter is very sluggish. i would expect that a modern 2 GHz computer can re-display the form as fast as a human can push the mouse around. But that's definitely not the case, and it takes about 200-300 ms before the form is fully re-adjusted. The form has about 100 visual controls on it, no code, or custom controls. How do i go about tracing who's the cause of the sluggishness?

• whats faster, more efficient, loading a js file with arrays or populating arrays from tables

  - by Leigh

  I am rebuilding an ecom site where the product data is stored in a multidimensional JS array that gets loaded on page load. This data is constantly being accessed with JS due to the nature of the site, to update prices based on user selections. There are many options that affect final price. From a programming standpoint, a DB table is much easier to maintain and update than are JS arrays, and since I am porting the site over to PHP and MYSQL, I have been considering moving these arrays into tables. So, would it be better to populate an array from the DB on load so that the pricing data is always available to the JS, or stay with hard coded JS files? I considered getting data via ajax as needed, but since this site has to constantly update pricing with user interaction, I have pretty much ruled that out. How would you handle it?

• What should be done first: Code reviews or Unit tests?

  - by goldenmean

  Hello, If a developer implements code for some module and wants to get it reviewed. What should be the order : *First unit test the module after designing test cases for the module, debugging and fixing the bugs and then give the modified code for peer code review (Pros- Code to be reviewed is 'clean' to a good extent. Reduces some avoidable review comments and rework. Cons- Developer might spend large time debugging/fixing a bug which could have pointed/anticipated in peer code reviews) Or *First do the code review with peers and then go for unit testing. What are your thoughts/experience on this? I believe this approach for unit testing, code reviewing should be programming language agnostic, but it would be interesting to know otherwise(if applicable) with specific examples. -AD

• BackgroundWorker RunWorkerCompleted in a Component

  - by Sphynx

  I'm familiar with the following: "If the operation raises an exception that your code does not handle, the BackgroundWorker catches the exception and passes it into the RunWorkerCompleted event handler, where it is exposed as the Error property of System.ComponentModel.RunWorkerCompletedEventArgs. If you are running under the Visual Studio debugger, the debugger will break at the point in the DoWork event handler where the unhandled exception was raised." However, I've encountered a weird glitch. In my component, there's an instance of BackgroundWorker. Even though it's not running in the debugger, the exception remains unhandled by the worker. Even simplified code produces an unhandled exception (and RunWorkerCompleted doesn't fire): Throw New ArgumentException("Test") The main thing is the code of RunWorkerComplete: RaiseEvent UpdateComplete(Me, New AsyncCompletedEventArgs(e.Error, e.Cancelled, e.Result)) I need the component to expose the worker exception through a public event. If I remove the RaiseEvent call, the exception becomes handled by the worker, and accessible through e.Error. Apparently, raising an event causes the worker to miss the exception. How can that be?

• Optimize loading an XAP file with an asp.net website

  - by theoneawaited

  I've been developing a game using Silverlight 4 and silversprite (http://silversprite.codeplex.com/) This game is HEAVILY content dependent, using a lot of audio and images. My content folder is around 90 mbs worth of stuff. And because of that, my XAP file is around 60 MB, and takes 5 minutes to download from the website before any user can start playing. I am using Visual Web Developer 2010 to create my site and load the XAP. Is there a way where I can take content out of my XAP and put it in my ASP.net site project? Or perhaps upload my content files to the site's storage? This would make my XAP file much quicker to download. Anyone have suggestions? Thanks!

  - by Arturo Guzman

  I´m new trying to make some apps using objective c, so I´ve an idea using uitableview but I don't imagine how can I get this. I´m trying to do something like you do in a spreadsheet where you have a fixed header and the first column too So when scroll the uitableview vertically the header will stay visible at top of the table and rows will change And finally when you scroll in horizontal direction the first cell of the row will stay visible and will change the header depending of how you scroll the uitableview I hope you could give me an idea how to get this, because I don't imagine how to do this, also I don´t have a lot of experience with this programming language.

• How to convert a C++ program that uses CUDA into MEX

  - by Harold Wellington Graves

  For work, I am converting the Image Denoising program that comes with the CUDA SDK into a MATLAB program. As far as I know, I have made all the necessary changes required by MATLAB, but when I try to call mex on it, MATLAB returns a bunch of linkage errors that I have no idea how to fix. If anyone has any suggestions on what I might be doing wrong, I would greatly appreciate it. The command I am giving MATLAB is: mex imageDenoisingGL.cpp -I..\..\common\inc -IC:\CUDA\include -L..\..\common\lib -lglut32 And the output from MATLAB is a bunch of these: imageDenoisingGL.obj : error LNK2019: unresolved external symbol __imp__cutCheckCmdLineFlag@12 referenced in function "void __cdecl __cutilExit(int,char * *)" (?__cutilExit@@YAXHPAPAD@Z) I am running: Windows XP x32 Visual Studio 2005 MATLAB 2007a

• Using Python tuples as vectors

  - by Etaoin

  I need to represent immutable vectors in Python ("vectors" as in linear algebra, not as in programming). The tuple seems like an obvious choice. The trouble is when I need to implement things like addition and scalar multiplication. If a and b are vectors, and c is a number, the best I can think of is this: tuple(map(lambda x,y: x + y, a, b)) # add vectors 'a' and 'b' tuple(map(lambda x: x * c, a)) # multiply vector 'a' by scalar 'c' which seems inelegant; there should be a clearer, simpler way to get this done -- not to mention avoiding the call to tuple, since map returns a list. Is there a better option?

  Hi, I need to make this show an error if the user tries to leave the page without checking this tickbox. It has no other use other than visual, is there a way to implement such a thing? <span> <input value="1" type="checkbox" name="salgsvilkar" ID="checkbox2" style="float:left;" onclick="document.getElementById('scrollwrap').style.cssText=' border-color:#85c222; background-color:#E5F7C7;';" /> <label for="checkbox2" class="akslabel"> Salgs og leveringsvilkår er lest og akseptert </label> </span> CSS is just for styling.
