• Multiple Questions per page using Drupal Quiz

  - by Andrew

  I'm using the Drupal Quiz module, and have setup some basic quizzes and stuff like that. However some further customization is required, involving more than 1 question per page, and a multi-type answer in this type of format: Question 1: Describe 4 things you did last summer a) [ short answer space - text field ] b) "I wept" c) "My whole family died so I learned self reliance" d) "I got another xbox" Question 2: Describe 2 things you hate about yourself a) "My arms are way shorter than my legs" b) "I was born without human emotion" So I guess in two parts, how to show multiple questions per page, and then how to allow multiple text fields for answers. Oh and this quiz is not graded, it's like a self assessment. Thanks!

• ASP.NET and Winforms: What PDF reporting tools are out there and recommended?

  - by Mark Redman

  I have ActiveReports for .Net which is a great tool, however the version I have is not going to support Visual Studio 2010. Active Reports quite pricey, so just wondering if there are any better alternatives out there at a competitive price or even open source, before I consider upgrading. I am looking for a reporting tool specifically, that has a designer and is programmable etc, not looking for something that can just produce PDF, eg iTextSharp etc. Output will primarily be PDF for web and windows applications. Using various databases, SQL Server, SQL Server Express, Azure and SQLite, so not sure SQL Server reporting services will work for all these cases. All coments appreciated.

• Dealing w/ Sqlite Join results in a cursor

  - by Bill

  I have a one-many relationship in my local Sqlite db. Pretty basic stuff. When I do my left outer join I get back results that look like this: the resulting cursor has multiple rows that look like this: A1.id | A1.column1 | A1.column2 | B1.a_id_fk | B1.column1 | B1.column2 A1.id | A1.column1 | A1.column2 | B2.a_id_fk | B2.column1 | B2.column2 and so on... Is there a standard practice or method of dealing with results like this ? Clearly there is only A1, but it has many B-n relationships. I am coming close to using multiple queries instead of the "relational db way". Hopefully I am just not aware of the better way to do things. I intend to expose this query via a content provider and I would hate for all of the consumers to have to write the same aggregation logic.

• Create UML diagrams after or before coding?

  - by ajsie

  I can clearly see the benefits of having UML diagrams showing your infrastructure of the application (class names, their members, how they communicate with each other etc). I'm starting a new project right now and have already structured the database (with visual paradigm). I want to use some design patterns to guide me how to code the classes. I wonder, should I code the classes first before I create UML diagram of it (maybe out of the code... seems possible) or should I first create UML diagram and then code (or generate code from the UML, seems possible that too). What are you experiences telling you is the best way?

• MySQL - Sort on a calculated value based on two dates

  - by Petter Magnusson

  I have the following problem that needs to be solved in a MySQL query: Fields info - textfield date1 - a date field date2 - a date field offset1 - a text field with a number in the first two positions, example "10-High" offset2 - a text field with a number in the first two positions, example "10-High" I need to sort the records by the calculated "sortvalue" based on the current date (today): If today=date2 then sortvalue=offset1*10+offset2*5+1000 else sortvalue=offset1*10+offset2*5 I have quite good understanding of basic SQL with joins etc, but this I am not even sure if its possible...if it helps I could perhaps live with a single formula giving the same sort of effect as the IFs do....ie. before date1 = low value, after date2 = high value...

• Statement hierarchy in programming languages

  - by sudo

  I quickly wrote an interpreter for some sort of experimental programing language i came up with, in PHP (yes, in PHP). The language itself doesn't have anything really special, I just wanted to give it a try. I got the basic things working (Hello World, input to output, string manipulation, arithmetics) but I'm getting stuck with the management of blocks and grouped statements. What I mean is: PHP and most other languages let you do this: ((2+2)*(8+2)+2), of course not only with mathematical computations. My program structure currently consists of a multidimensional array built like this: ID => Type (Identifier, String, Int, Newline, EOF, Comma, ...) Contents (If identifier, int or string) How could I allow statements to be executed in a defined order like in the PHP example above?

• python interactive web data/forms/interface communicating with remote server

  - by decipher

  What's an efficient method (preferably simple as well) for communicating with a remote server and allowing the user to 'interact' with it (IE submit commands, user interface) via the web browser (IE a text box to input commands, and an text area for output, or various command-less abstracted interfaces)? I have the 'standalone' python code finished for communicating and working(terminal/console based right now). My primary concern is with re-factoring the code to suite the web, which involves establishing a connection (python sockets), and maintaining the connection while the user is logged on. some further details: currently using django framework for the basic back end/templates.

• Strange fstream problem

  - by noname

  Hi, I have really strange problem. In Visual C++ express, I have very simple code, just: #include <fstream> using namespace std; int main() { fstream file; file.open("test.txt"); file<<"Hello"; file.close(); } This same code works OK in my one project, but when I create now project and use this same lines of code, no file test.txt is created. Please, what is wrong?¨ EDIT: I expect to see test.txt in VS2008/project_name/debug - just like the first functional project does.

• Asp.net Site on GoDaddy Loads Slowly

  - by Randy

  I just published a very small site to GoDaddy that I programmed in Microsoft Visual Web Developer 2008. The site only contains 6 sheets, none of which are data intensive. Each has a few small images that serve mostly to navigate to the other sheets. There is no data, no SQL, nothing like that. There is one master page that governs the page layout for all of the pages. Everything works fine, for the most part. I am posting because the site loads quite slowly, particularly considering how little content is being loaded. Can anybody give me any advice about what I should look at to speed this thing up a little bit? Is this an asp.net issue? Use of master pages? Godaddy? Something else? I'm a newbie, so speak slowly. Thanks.

• drupal bootstrap script: how to get list of all nodes of type x?

  - by groovehunter

  hi. I create a custom import and export, at the moment as an external script (via bootstrap), i plan to create a module in a more generic fashion lateron. I am building a frontend for nagios and for our host management and nagios configuration btw. Maybe it might become useful for other environments (networkmanagement) Now i need to know how to get list of all nodes of type x? I want to avoid direct SQL. A suggestion i got was to make an rss and parse it but i acess the drupal db a dozen times to extract various nodes, so it feels strange to do a web request for one thing So what i am looking for as newbie drupal dev is just a pointer to basic search module api for this task TIA florian

• Learning Spring MVC For web-projects

  - by John

  I have looked at Spring MVC a few times briefly, and got the basic ideas. However whenever I look closely it seems to require you already know a whole load of 'core Spring'. The book I have for instance has a few hundred pages before it gets onto Spring MVC... which seems a lot to wade through. I'm used to being able to jump in, but there's so much bean-related stuff and XML, it just looks like a mass of data to consume. Does it simplify if you put the time in, or is Spring just a much bigger framework than I thought? is it possible to learn this side of it in isolation?

• 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.

• Setting up a non-emacs Common Lisp Dev Env for web application development?

  - by Ravi S

  I am trying to set up a Common Lisp Dev Env for web application development on my Ubuntu 10.04 LTS 64-bit box and I can't find a single decent guide that is targeted at noobs. The closest I came is with Peter Seibel's Lisp in a box but I detest Emacs with a passion and it seems to have older versions of SBCL and CLISP (which are my preferred CL implementations). I do not want to use any of the commercial implementations. I am looking for a simple setup to write some very basic CRUD apps involving possibly hunchentoot, some framework like weblocks,CL-WHO, CL-SQl, sqlite or some datastores from the nosql family like mongo and couch.. Assuming, I go with either SBCL or CLISP on Linux, what is the best tool to manage packages and libraries? ASDF? I am looking for simplicity and consistency and I don't expect to use a ton of libs...

• Console.Write Not Working In Win Forms App

  - by Steven

  I created a VB.NET Windows Forms Application in Visual Studio 2008. When I run my program from the command-line, I get no output (only the next prompt). What am I doing wrong? Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Debug.Write("Foo") Debug.Flush() Console.WriteLine("foo") Console.Beep(800, 100) 'confirm this function is called' Me.Close() End Sub EDIT: Can a program have a form and a console? EDIT2: Ho's answer works. However, the output appears on the next command-line prompt. Can a Winforms application tell the command-line to wait until it's finished instead of immediately returning?

• Debugging ASP.NET on a built-in web server suddenly stops

  - by Anton Gogolev

  I have Windows Server 2008 (64-bit), VS 2008 with its built-in webserver and an ASP.NET MVC 1.0 webapp. All I'm trying to do is to debug said app. I have a bunch of breakpoints, but they behave in a very strange way. When I fist start a debugging session with F5 and hit a breakpoint, the debugger stops just fine. However, after serveral F10s/F11s debugging suddenly "stops" (no exceptions at that time), but neither VS detaches from browsers' process, nor webapp execution stops: Visual Studio stays attached, and web request continues executing as usual. I tried various browsers (Chrome, Firefox, IE), but to no avail. What do I do to solve this? It really drives me insane.

• Using query parameter in Access report

  - by Dave

  I have a very basic access database where a query returns the sales made within a set start date and a set end date. The dates are set with two pop up boxes for the user to enter, first the start date, and then the end date. I have a report running off the back of this. How can I (using VBA) get at these dates then display them on the report - ie. the report says "Sales for Period:" and then shows the "from date" and the "to date" that the user input.

• copying program arguments to a whitespace separated std::string

  - by PaulH

  I have a Visual Studio 2008 C++ application where I would like to copy all of program arguments in to a string separated by a whitespace " ". i.e., if my program is called as foo.exe \Program Files, then my folder string below would contain \Program Files Below is an example of what I'm doing now. I was wondering if there was a shorter or easier method of doing this. Is there an easy way to eliminate the std::wstringstream variable? int _tmain( int argc, _TCHAR* argv[] ) { std::wstringstream f; std::copy( argv + 1, argv + argc, std::ostream_iterator< std::wstring, wchar_t >( f, L" " ) ); std::wstring folder = f.str(); // ensure the folder begins with a backslash if( folder[ 0 ] != L'\\' ) folder.insert( 0, 1, L'\\' ); // remove the trailing " " character from the end added by the std::copy() above if( *folder.rbegin() == L' ') folder.erase( folder.size() - 1 ); // ... } Thanks, PaulH

• Correct ifdef for DWORD_PTR, INT_PTR, LONG_PTR, UINT_PTR, ULONG_PTR etc?

  - by user9876

  There are some new integer types in the Windows API to support Win64. They haven't always been suppoprted; e.g. they aren't present in MSVC6. How can I write an #if condition to detect if these types are supported by <windows.h>? (My code needs to compile under many different versions of Microsoft Visual C++, including MSVC6. So I need to provide my own definitions of these types, with an #if to disable them in newer compilers).

• Getting "longnamesfirst" option to work with natbib in LaTeX - custom .bst

  - by jkale

  Hey all, I'm writing an MSc dissertation and I'm having difficulty getting the longnamesfirst option working in natbib. My University has a very specific referencing style a little like APA, but not quite the same. I've used the docstrip utility to build a basic framework and then edited it to fit the requirements of my University. Having tested it with the simplest possible document; applying my bst then trying it again with one of the defaults (\bibliographystyle{apacite}) I can see than natbib works as intended with apacite. It doesn't however produce correct results with my bst. So my question: How does the .bst file link with natbib to enforce the "longnamesfirst" option?

• Problem with datagridvieew in vb.net

  - by user225269

  I'm trying to add a datagridview in vb.net, but it does not allow me to change the connection string or the database that should be imported to connect to it. The only thing that I'm seeing is the previous ms sql database that I connected with datagridview and everytime I click the new connection, the window closes and it leaves me with the datagridview with the previous connection that I have. And its not applicable because, now I want to connect it with mysql. Not ms sql. Its some sort of a cache like feature in vb.net, how do I get rid of it. so that I can add the new connection for mysql? Do I need to reinstall visual studio 2008?

• Can a CWinApp be placed in a DLL?

  - by jmucchiello

  I'm updating some legacy apps to Visual Studio 10 and am in linker hell. All of these DLLs derive classes from CWinApp and use AfxGetApp() to get access to the object. When I link the DLLs I get unresolved externals that look like global static objects that would get pulled in by a normal app's main(): Shell.lib(SHELL.obj) : error LNK2001: unresolved external symbol "public: static struct CRuntimeClass const CException::classCException" (?classCException@CException@@2UCRuntimeClass@@B) Shell.lib(SHELL.obj) : error LNK2001: unresolved external symbol "public: static struct CRuntimeClass const CFrameWnd::classCFrameWnd" (?classCFrameWnd@CFrameWnd@@2UCRuntimeClass@@B) Shell.lib(SHELL.obj) : error LNK2001: unresolved external symbol "public: static class CRect const CFrameWnd::rectDefault" (?rectDefault@CFrameWnd@@2VCRect@@B) My current combination of ignore default libraries and additional libraries (the method you can easily google to find the answer to linker hell) is: msvcprtd.lib,mfc100d.lib,mfcs100d.lib,libcmtd.lib When I add nafxcwd.lib (the mfc library), these three external symbols resolve but I end up with a bunch of other duplicate symbols (requiring the use of /FORCE:MULTIPLE) and in end __argc and __argv become unresolved. So the basic question is: Can you link a DLL containing a CWinApp in VS10? How do you setup the linker to do it?

• The width of a list that contains an embedded matrix grows unexpectedly

  - by Greg Lorenz

  I have a report in reporting services 2005 that includes a list with an embedded matrix and am attempting to put a border on the list, however, when I run the report in visual studio the matrix is growing past the end of the page and therefore the boarder is growing with it causing it to grow into the second page. It appears that there was supposedly a fix for this in reporting services 2000 service pack 1 but I am still experianceing the issue in 2005. The list has a details group that limits the records on a row to 4 using the following expression: =ceiling(rownumber("list1")/4), the matrix has a column group that should recycle those based on the rownumber determined by the list using the following expression: =rowNumber("list1_Details_Group") I have also attempted to put the list in a rectangle in hopes to stop the matrix from growing to no avail. How do I effectivly stop the matrix form growing past the space allowed by the list control?

• using libcurl to create a standalone site-polling program

  - by aitchnyu

  I am creating a standalone (no DLLs) windows C/C++ program that uses HTTP POST to periodically send data to an HTTP server. I identified libCURL as the HTTP client library as it seems simple and reliable. I still need to identify the environment (an IDE) which I can use to develop my project. My program has: poller- which checks the status of the connection a file writer when polled link is down a component which POSTs the file when link is up What is the appropriate IDE for this project? I heard endorsements for DevC++ and Visual C. I am a newb to coding and this site. Pardon me if I am unclear in anything.
