• C++ MFC add combo box string item from a widget ID

  - by OzBarry

  I've added a combo box in the gui editor in MSVC 2010 pro in my MFC project. I have a list of strings I am grabbing from an external source and want to add them to my combo box. I've searched for a while, and every post seems to suggest I need to use the CComboBox class, however, I have no idea how to get the class variable from the resource ID of the combobox element in the gui editor. In summary, how do I add a string to my combo box, either using a macro (like CB_ADDSTRING(RESOURCE_ID, "my string");) or using CComboBOx (something like CComboBox::GetObject(RESOURCE_ID)->AddString("blah");). I do not do much win32 api/mfc programming, and just started fiddling around with it.

• Where can I find "reference barcodes" to verify barcode library output?

  - by mjustin

  This question is not about 'best' barcode library recommendation, we use various products on different platforms, and need a simple way to verify if a given barcode is correct (according to its specification). There are some free online bar code generators in the Internet, and I found many differences between their output and our library output regarding graphics and text field below the code. Now I am not sure which one is wrong, and before filing bug report I want to make sure how the correct barcode should look like. We mainly need Code128 and UCC/EAN-128 with A/B/C subcodes. Which resource would you suggest?

• Ideas for using R to create a T-shirt design (for useR 2010) ?

  - by Tal Galili

  There is now a competition for creating a T-shirt design for useR2010. Someone proposed the idea to use R for creating the T-shirt image. Which leads me to my questions: What type of images do you think might be fitting for this? How would you suggest to use R to create the images ? Would anyone here want to have a go at it? (p.s: I understand this is not a pure "programming" question. Yet it involves R programming, the understanding of R aesthetics, and some caring for the R community. I also understand I am at the risk of annoying people here with this question, so in case that happens - I deeply apologies! My only justification is that I am acting in good faith and in the purpose of having nice things for R users to enjoy, while learning something in the process) Related thread I once opened: http://stackoverflow.com/questions/2162131/how-can-i-learn-to-create-beautiful-infographics-with-connection-to-my-r-knowled

• How to Iterate a Resharper Template ?.

  - by sree

  I have a small Resharper Template I have written for Null check of a function Parameter (C#). Check.IsNotNull($param$, "$param$"); - Suggest Parameter - #1 I can now null check the function paramters one by one. But I want to be able to null check all the paramters at once through a template. Is it Possible in Resharper?. Is there someting like a "$Foreach" using which I can loop through parameter variables and write the code to check them one by one ?. (without writing out the foreach into the code) I see that the "Alt + Ins" does something similar. (Taking all Properties on the class and making them as parameters of a constructor). So hoping that there's a way out.

• Scanner's Read Line returning NoSuchElementException

  - by Brian

  This is my first time using StackOverflow. I am trying to read a text file which consists of a single number one the first line. try { Scanner s = new Scanner(new File("HighScores.txt")); int temp =Integer.parseInt(s.nextLine()); s.close(); return temp; } catch (FileNotFoundException e) { // TODO Auto-generated catch block e.printStackTrace(); } However, I get an error: java.util.NoSuchElementException: No line found at java.util.Scanner.nextLine(Unknown Source) at GameStart.getHighScore(GameStart.java:334) at GameStart.init(GameStart.java:82) at sun.applet.AppletPanel.run(Unknown Source) at java.lang.Thread.run(Unknown Source) I know that HighScores.txt is not empty, so why is this problem occuring? I tried using BufferedReader, and BufferReader.readLine() return null.

• Function return type style

  - by JB

  I'm learning c++0x, at least the parts supported by the Visual C++ Express 2010 Beta. This is a question about style rather than how it works. Perhaps it's too early for style and good practice to have evolved yet for a standard that isn't even released yet... In c++0x you can define the return type of a method using - type at the end of the function instead of putting the type at the start. I believe this change in syntax is required due to lambdas and some use cases of the new decltype keyword, but you can use it anywhere as far as I know. // Old style int add1(int a, int b) { return a + b; } // New style return type auto add2(int a, int b) -> int { return a + b; } My question really then, is given that some functions will need to be defined in the new way is it considered good style to define all functions in this way for consistency? Or should I stick to only using it when necessary?

• SharePoint SLK and T-SQL xp_cmdshell safety

  - by Mitchell Skurnik

  I am looking into a TSQL command called "xp_cmdshell" to use to monitor a change to a the SLK (SharePoint Learning Kit) database and then execute a batch or PowerShell script that will trigger some events that I need. (It is bad practice to modify SharePoint's database directly, so I will be using its API) I have been reading on various blogs and MSDN that there are some security concerns with this approach. The sites suggest that you limit security so the command can be executed by only a specific user role. What other tips/suggestions would you recommend with using "xp_cmdshell"? Or should I go about this another way and create a script or console application that constantly checks if a change has been made? I am running Server 2008 with SQL 2008.

• What is good practice for writing web applications that control daemons (and their config files)

  - by Jones R

  Can someone suggest some basic advice on dealing with web applications that interact with configuration files like httpd.conf, bind zone files, etc. I understand that it's bad practice, in fact very dangerous to allow arbitrary execution of code without fully validating it and so on. But say you are tasked to write a small app that allows one to add vhosts to an apache configuration. Do you have your code execute with full privileges, do you write future variables into a database and have a cron job (with full privileges) execute a script that pulls the vars from the database and throws them into a template config file, etc. Some thoughts & contributions on this issue would be appreciated. tl;dr - how can you securely write a web app to update/create entries in a config file like apache's httpd.conf, etc.

• Should I learn Haskell or F# if I already know OCaml?

  - by Unknown

  I am wondering if I should continue to learn OCaml or switch to F# or Haskell. Here are the criteria I am most interested in: Longevity Which language will last longer? I don't want to learn something that might be abandoned in a couple years by users and developers. Will Inria, Microsoft, University of Glasgow continue to support their respective compilers for the long run? Practicality Articles like this make me afraid to use Haskell. A hash table is the best structure for fast retrieval. Haskell proponents in there suggest using Data.Map which is a binary tree. I don't like being tied to a bulky .NET framework unless the benefits are large. I want to be able to develop more than just parsers and math programs. Well Designed I like my languages to be consistent. Please support your opinion with logical arguments and citations from articles. Thank you.

• Advice Needed on Development of ConnectionWizard Custom Control

  - by SidC

  I have the need for an ASP.NET custom server control that will check the web.config file for a connectionstring name, prompt the user to create said connectionstring if not present, and execute create table stored procedures using the connection. This control will be embedded into a webpart for use in a WSS3.0 solution. Can anyone suggest some good tutorials on creating this type of control - specifically addressing use of connectionstrings? What methods/classes do I need to setup? Should I use the p&p data application block for this project? Thanks, Sid

• Is there an easy way to do click-and-drag scrolling in text frames?

  - by Skilldrick

  I have a div with overflow:auto and a scroll bar, and I'd like to be able to drag the contents to scroll. I don't need to be able to select text. Is there an easy way to do this? A jQuery plugin would be good, otherwise plain old JavaScript would be fine. It seems I haven't made myself clear enough. There's a div with a fixed height that I want to scroll. Instead of picking up the scroll bar, I want to click and drag inside the text in the opposite direction. Like on an iPhone. Like in Photoshop when you hold down space and drag. ------------------- | | | | | | | ||| | | | | <----------- click here and drag to scroll. | | | | | | -------------------

• Storing expression template functors

  - by UncaughtException

  Hello guys, at the moment I'm really interested in expression templates and want to code a library for writing and differentiating mathematical functions with a lambda-style syntax. At the moment, I'm able to write (_x * _x)(2); and get the correct result 4. But I would really like to do something like MathFunction f = _x * _x; f(2);, but I don't have any ideas on how to cope with the recursive expression templates on the right side. Is it possible to achieve this without using the 'auto'-Keyword instead of MathFunction or having to make the operator() virtual? Thanks for your help!

• Declaration for object for which creation is wrapped in macro

  - by learner

  The following macro is defined in our code: #define MSGMacro(obj, arg) MyPaymentClass obj(arg) Where MSGMacro is used to creates the object of type MyPaymentClass using code like MSGMacro(Card, 1); MSGMacro(Cash, 2); ---- ---- //removed unwanted things to keep question cleaner. All the above code is in one cpp file, Now the problem is how we can expose these two objects of MyPaymentClass to other units in my project? i.e. I want to use Card and Cash in other CPP files. Please suggest how I can give the declaration for the same in some header file?

• Creating a stored procedure in SQL Server 2008 that will do a "facebook search"

  - by dig

  Hello, I'm trying to implement a facebook search in my system (auto suggest while typing). I've managed to code all the ajax stuff, but I'm not sure how to query the database. I've created a table called People which contains the fields: ID, FirstName, LastName, MiddleName, Email. I've also created a FTS-index on all those fields. I want to create a stored procedure that will get as a parameter the text inserted in the query box and returns the suggestions. For example, When I will write in the textbox the query "Joh Do" It will translate to the query: select * from People where contains(*, '"Joh*"') and contains(*, '"Do*"') Is there a way to do that in stored procedure? P.S I've tried to use the syntax select * from People where contains(*,'"Joh*" and "Do*"') but it didn't returned the expected results, probably because it needs to search the words on different fields. Is there a way to fix that? Thanks.

• Visaul Studio 2010, TlbImp generates .net 4.0 interops in 2.0 projects

  - by DJScrib

  In a C# project we add a reference to a COM object via the Add References setup pointing to a COM object which results in the IDE auto-generating the interop assembly. So this is fine and good, but we are building based on .net 3.5 SP1 aka CLR 2.0, and the generated interops are using the 4.0 CLR making them incompatiable. Is there a way to prevent this? I assume the other option is in our build script to try using tlbimp.exe with the /references parameter? to point to mscorlib v2.0? Anyhow, I'm hoping there's a flag somewhere to allow this.
