• From comma separated list to individual item result set. *mysql

  - by Raziel

  I'm doing some data migration from a horribly designed database to a less horribly designed database. There is a many to many relationship that has a primary key in one table that corresponds to a comma separated list in another. FK_ID | data ------------- 1,2 | foo 3 | bar 1,3,2 | blarg Is there a way to output the FK_ID field with each comma separated element as a single line in the result set? result set FK_ID | data ------------- 1 | foo 2 | foo 3 | bar 1 | blarg 2 | blarg 3 | blarg I'm thinking this would require some sort of recursive query which I don't think mysql has. Thanks in advance.

• DisplayName attribute from Resources?

  - by Palantir

  Hello! I have a localized application, and I am wondering if it is possible to have the DisplayName for a certain model property set from a Resource. I'd like to do something like this: public class MyModel { [Required] [DisplayName(Resources.Resources.labelForName)] public string name{ get; set; } } But I can't to it, as the compiler says: "An attribute argument must be a constant expression, typeof expression or array creation expression of an attribute parameter type" :( Are there any workarounds? I am outputting labels manually, but I need these for the validator output!

• Passing a Structure containing an array of String and an array of Integer into a C++ DLL

  - by DanJunior

  I'm having problems with marshaling in VB.NET to C++, here's the code : In the C++ DLL : struct APP_PARAM { int numData; LPCSTR *text; int *values; }; int App::StartApp(APP_PARAM params) { for (int i = 0; i < numLines; i++) { OutputDebugString(params.text[i]); } } In VB.NET : <StructLayoutAttribute(LayoutKind.Sequential)> _ Public Structure APP_PARAM Public numData As Integer Public text As System.IntPtr Public values As System.IntPtr End Structure Declare Function StartApp Lib "AppSupport.dll" (ByVal params As APP_PARAM) As Integer Sub Main() Dim params As APP_PARAM params.numData = 3 Dim text As String() = {"A", "B", "C"} Dim textHandle As GCHandle = GCHandle.Alloc(text) params.text = GCHandle.ToIntPtr(textHandle) Dim values As Integer() = {10, 20, 30} Dim valuesHandle As GCHandle = GCHandle.Alloc(values) params.values = GCHandle.ToIntPtr(heightHandle) StartApp(params) textHandle.Free() valuesHandle.Free() End Sub I checked the C++ side, the output from the OutputDebugString is garbage, the text array contains random characters. What is the correct way to do this?

• How to begin writing an Application Server over Apache?

  - by Cracker

  For my college project, I want to create a simple application server in C that runs over Apache. Like .php, .asp, .jsp, the extension of my files would be .sas. I have already written a parser which reads the .sas files and generates the output. For example, consider a file index.sas with the below code: <% echo "Hello"; %> Now, if I execute: sas index.sas The result would be: Hello Now I want to use this program as an application server over Apache just as PHP, Tomcat, etc. work over Apache. I have heard of cgi-bin but I think PHP uses a different approach. I want to learn the approach which PHP uses. Please advice.

• How can I convert a file full of unix time strings to human readable dates?

  - by skymook

  I am processing a file full of unix time strings. I want to convert them all to human readable. The file looks like so: 1153335401 1153448586 1153476729 1153494310 1153603662 1153640211 Here is the script: #! /bin/bash FILE="test.txt" cat $FILE | while read line; do perl -e 'print scalar(gmtime($line)), "\n"' done This is not working. The output I get is Thu Jan 1 00:00:00 1970 for every line. I think the line breaks are being picked up and that is why it is not working. Any ideas? I'm using Mac OSX is that makes any difference.

• jQuery .getJSON() Not Parsing All Objects

  - by Brad

  I'm using jQuery's .getJSON function to parse a set of search results from a Google Search Appliance. The search appliance has an xslt stylesheet that returns the results as JSON data, which I validated with both JSONLint and Curious Concept's JSON Formatter. According to FireBug, the full result set is returned from the XMLHTTPRequest, but I tried dumping the data (with jquery.dump.js) and it only ever parses back the first result. It does successfully get all the Google Search Protocol stuff, but it only ever sees one "R" object (or individual result). Has anybody had a similar problem with jQuery's .getJSON? I know it likes to fail silently if the JSON is not valid, but like I said, I validated the results with several validators and it should be good to go. Edit: Clicking this link will show you the JSON results returned for a search for the word "google": http://bigbird.uww.edu/search?client=json_frontend&proxystylesheet=json_frontend&proxyrefresh=1&output=xml_no_dtd&q=google jQuery only retrieves the first "R" object, even though all "R" objects are siblings.

• How to remove htmlentities() values from the database?

  - by Chris

  Long before I knew anything - not that I know much even now - I desgined a web app in php which inserted data in my mysql database after running the values through htmlentities(). I eventually came to my senses and removed this step and stuck it in the output rather than input and went on my merry way. However I've since had to revisit some of this old data and unfortunately I have an issue, when it's displayed on the screen I'm getting values displayed which are effectively htmlentitied twice. So, is there a mysql or phpmyadmin way of changing all the older, affected rows back into their relevant characters or will I have to write a script to read each row, decode and update all 17 million rows in 12 tables?

• Which C++ graph library should I use?

  - by mspoerr

  Hello, I found the following graph libraries, but I am not sure which one I should use. Maybe there are some more... Graphviz (http://www.graphviz.org/) Boost Graph Library (http://www.boost.org/doc/libs/1_42_0/libs/graph/doc/index.html) Lemon (http://lemon.cs.elte.hu/trac/lemon) igraph (http://igraph.sourceforge.net/introduction.html) What it should do: draw a undirected network map come as header only or static lib for Windows the output format should be user editable Graphviz is the only one I tried so far, but I found no static lib for it, I failed to build it by my own and the documentation could be better. Therefore I looked around and found these other three libs. I would be glad to get some recommendations which lib to choose. Thanks, /mspoerr

• Check result of AX_PYTHON_MODULE in configure.ac

  - by tmatth

  In using the m4_ax_python_module.m4 macro in configure.ac (AX_PYTHON_MODULE), one can know at configure time if a given module is installed. It takes two arguments, the module name, and second argument which if not empty, will lead to an exit, useful when the module is a must-have. In the case where you don't want a fatal exit, how do you test in configure.ac which modules were found or not? They output "yes" or "no" when configure is run, but that's all I've found so far. Basically If I have these lines in configure.ac: AX_PYTHON_MODULE(json,[]) AX_PYTHON_MODULE(simplejson,[]) How do I test which of the two modules were found? See http://www.gnu.org/software/autoconf-archive/ax_python_module.html#ax_python_module for documentation about this macro.

• Log with timestamps that have millisecond accuracy & resolution in Windows C++

  - by Psychic

  I'm aware that for timing accuracy, functions like timeGetTime, timeBeginPeriod, QueryPerformanceCounter etc are great, giving both good resolution & accuracy, but only based on time-since-boot, with no direct link to clock time. However, I don't want to time events as such. I want to be able to produce an exact timestamp (local time) so that I can display it in a log file, eg 31-12-2010 12:38:35.345, for each entry made. (I need the millisecond accuracy) The standard Windows time functions, like GetLocalTime, whilst they give millisecond values, don't have millisecond resolution, depending on the OS running. I'm using XP, so I can't expect much better than about a 15ms resolution. What I need is a way to get the best of both worlds, without creating a large overhead to get the required output. Overly large methods/calculations would mean that the logger would start to eat up too much time during its operation. What would be the best/simplest way to do this?

• Extracting startup errors from Spring contexts

  - by sehugg

  Consider the following output from a Tomcat server under Eclipse: INFO: Initializing Coyote HTTP/1.1 on http-8080 INFO: Initialization processed in 634 ms INFO: Starting service Catalina INFO: Starting Servlet Engine: Apache Tomcat/6.0.20 SEVERE: Error listenerStart SEVERE: Context [/MyServlet] startup failed due to previous errors I would like to figure out what exception caused "Error listenerStart", but Spring seems to be preventing me from finding the error via Eclipse. I'd love to start Catalina manually, but that doesn't seem to do anything. What's the best way to find the hidden exception? I'm not afraid to use torture methods.

• Best tools / formats for documenting XML API?

  - by ivant

  We are developing XML over HTTP service and we need a way to document the XML interface. Our supported XMLs generally are subsets of some industry standard XML API, which unfortunately lacks any good documentation. It has XSDs though with some annotations, so we use this go generate the initial documentation and then remove the unsupported parts and refine the result. But this process is tedious and the results aren't at all great. Any suggestion about documentation formats and tools? I prefer to have HTML output and possibly more, e.g. PDF. Oh, and we are mixed Linux and Windows shop, so the tools should work well on both.

• Constructor Type Coercion in C++

  - by Robert Mason

  Take the following class: class mytype { double num; public: mytype(int a) { num = sqrt(a); } void print() { cout << num; } } Say there is a method which takes a mytype: void foo(mytype a) { a.print(); } Is it legal c++ (or is there a way to implement this) to call foo(4), which would (in theory) output 2? From what I can glean you can overload type casts from a user defined class, but not to. Can constructor do this in a standards-compliant manner (assuming, of course, the constructor is not explicit). Hopefully there is a way to in the end have this legal: int a; cin >> a; foo(a); Note: this is quite obviously not the actual issue, but just an example for posting purposes. I can't just overload the function because of inheritance and other program-specific issues.

• How can I see who in my team are writing the most code and who is writing the least using TFS?

  - by kjm

  I am having a problem with one of my team members output. He seems to be always 'busy' yet I am unable to see exactly what code he has done and he seems be delivering very little and it seems to take a long time to do so. I'd like to investigate further using TFS and was wondering if there is any functionality in TFS that shows what has been written by an individual or similar? Just to clarify I am NOT spying I am trying to resolve situation. This is only a starting point. I un derstand that quantity of code does not equate to best programmer thanks for any answers

• MSSQL "for xml", multiple tables, multiple nodes

  - by Nelson

  Is it possible to select multiple tables at once? For example, I can do: SELECT ( SELECT * FROM Articles FOR XML PATH('article'), TYPE ) FOR XML PATH('articles'), ROOT('data') and SELECT ( SELECT * FROM ArticleTypes FOR XML PATH('articleType'), TYPE ) FOR XML PATH('articleTypes'), ROOT('data') Can I join both so that I get the following output? I can't use UNION because the table structures don't match. <data> <articles> <article>...</article> ... </articles> <articleTypes> <articleType>...</articleType> ... </articleTypes> </data>

• Maven - add dependency on artifact source

  - by Jacob Hansson

  I have two maven modules, one that ends up as a jar, and one war that depends on that jar. I want the jar module to package it's source code together with the compiled classes in the jar, so that the second module is able to access it. I have tried using the maven-source-plugin, but I am confused as to how to add a dependency on the output of that. It seems that the dependency by default goes to the compiled jar, and not the source-code jar (ending with "-source.jar") that maven-source-plugin creates. How do I add the "-source.jar" as a dependency, while still preserving the dependency on the compiled sources?

• How are variables bound to the body of a define_method?

  - by Chris

  While trying to brush up my Ruby skills I keep running across this case which I can't figure out an explanation for by just reading the API docs. An explanation would be greatly appreciated. Here's the example code: for name in [ :new, :create, :destroy ] define_method("test_#{name}") do puts name end end What I want/expect to happen is that the name variable will be bound to the block given to define_method and that when #test_new is called it will output "new". Instead each defined method outputs "destroy" -- the last value assigned to the name variable. What am I misunderstanding about define_method and its blocks? Thanks!
