• Storing SQL in MySQL: Insert as Text?

  - by Tim F

  Hey all, Working in a team environment, each one of us has put together our own list of SQL statements that we use to help with our day to day job functions. As the case often is, there may be some redundancy with this, and we are often in need of each other's statements. To circumvent this, I'm looking to put together a small app that can be used to store and search for these SQL statements. To begin with, I'm keeping it basic, just storing and searching the statements. This may build out to be the actual execution at some point in the future, but I'm not concerning myself with this at the time. This will be built with PHP and MySQL - Should I store the SQL as text, or is there something that I need to be concerned with?

• Did anybody use the constream (constrea.h) lib?

  - by user337938

  Two years ago, I used the conio.h (actually conio2.h for Dev-C++) to create a console form interface. Now I want to make the same thing, but C++ std lib does not provide the needed functions and I don't want to use the old C conio lib. I found some websites which highlights the constream lib, but I have no idea to use it on VS! I tried just copying the header file into my project, but VS show several erros. I believe I am doing something wrong. ps: i got this file: ftp://ftp.cs.technion.ac.il/pub/misc/baram/TC31/INCLUDE/CONSTREA.H

• Can single-buffer blocking WSASend deliver partial data?

  - by CodeAngry

  I've pretty much always used send() with sockets and now I'm moving onto the WSA functions. With send(), I have a sendall() helper that ensured all data is delivered even if it didn't happen in one try and a partial send occurred on first call. So, instead of learning the hard way or over-complicating code when I don't have to, decided to ask you: Can a blocking WSASend() send partial data or does it send everything before it returns or fails? Or should I check the bytes sent vs. expected to send and keep at it until everything is delivered? ANSWER: Overlapped WSASend() does not send partial data but if it does, it means the connection has terminated. I've never encountered the case yet.

• How to reference filtered ng-repeat items from a controller in AngularJS

  - by ParkerDigital

  I have some JSON data that is rendered out via the ng-repeat directive, and the results are then filtered via some checkboxes/drop-downs, and some custom filter functions in my controller. I now want to add a function to my controller that is triggered by an 'ng-change' on some of the checkboxes, that can reference the current list of items in my 'ng-repeat'. I realise I can reference these values from a custom filter, for example $scope.filterProvider = function(item), but this function is then called for each and every item in the ng-repeat, which isn't what I want - I want the function to just be called each time a checkbox is checked/unchecked, and I need that function to be able to reference the items in my ng-repeat...does that make sense to anyone?! And if so, does anyone know how I can do that? Thanks :-)

• Pass, edit and return variable in C

  - by Supertecnoboff

  I am new to C programming and recently I have been playing around with functions in C programming. But I have a simple problem: Basically I want to pass an integer to a function, have the function edit it and then pass back the integer to the main function. I am working on this but it isn't working..... Here is my code: int update_SEG_values(int DIGIT_1, int DIGIT_2) { // How many tens in the "TEMP_COUNT". DIGIT_2 = ((TEMP_COUNT) / 10); // How much is left for us to display. TEMP_COUNT = TEMP_COUNT - ((DIGIT_2) * 10); // How many ones. DIGIT_1 = ((TEMP_COUNT) / 1); return(DIGIT_1, DIGIT_2); } What am I doing wrong here?

• C++ & C#, how to create wrapper dll in C++ for C# to call instance function in C++ dll?

  - by 5YrsLaterDBA

  Received an unmanaged C++ dll with instance functions which need to be called from my C#. need to write a wrapper C++ dll to bridge the C# and original C++ dll as suggested by experts here. it is new to me and want to learn from you. Header file of the original C++ dll likes this: class EXPORT_MACRO NB_DPSM { private: string sFileNameToAnalyze ; public: NB_DPSM(void); ~NB_DPSM(void); void setFileNameToAnalyze(string FileNameToAnalyze) ; int WriteGenbenchData(string& message) ; }; Start from a Class Library project template or CLR Empty Project template? What's the wrapper code should look like? Anywhere has step by step example for this? thanks,

• If I write a framework that gets information from the Internet, should I make a degelate or use blocks?

  - by Time Machine

  Say I'm writing a publicly available framework for the Vimeo API. This framework needs to get information from the Internet. Because this can take some time, I need to use threadin to prevent the UI from hanging. Foundation uses delegates for this, like NSURLConnectionDelegate. However, Game Kit uses blocks as callback functions. What is the recommended way of doing this? I know blocks aren't supported in standard GCC versions, but they require less, much less code for the one that uses my framework. Delegates, on the other hand, are real methods and when protocols are used, I'm sure the methods are implemented. Thanks.

• DataTable from TextFile?

  - by Craig

  I have taken over an application written by another developer, which reads data from a database, and exports it. The developer used DataTables and DataAdaptors. So, _dataAdapter = new SqlDataAdapter("Select * From C....", myConnection); and then ExtractedData = new DataTable("CreditCards"); _dataAdapter.Fill(ExtractedData); ExtractedData is then passed around to do different functions. I have now been told that I need to, in addition to this, get the same format of data from some comma separated text files. The application does the same processing - it's just getting the data from two sources. So, I am wondering if I can get the data read into a DataTable, as above, and then ADD more records from a CSV file. Is this possible?

• Is it possible to wrap calls to statically linked 3rd party library?

  - by robusta

  Hi, I would like to trace calls to some 3rd party library which are made from another 3rd party library. Example: I want to trace calls to library A. My application statically links library B, which in turn is statically linked to library A. In case of dynamic linking I could write library A2 with wrappers for functions which I want to trace of library A and use LD_PRELOAD=A2.so. Then, my wrappers will be called instead, and I will see the trace. In my case I cannot use dynamic linking. Is it possible to achieve the same using static linking? Thanks, Robusta

• How to efficiently render different things at different times in a game?

  - by Baqjohanson

  Sorry for the ambiguous title. What I am wondering is what is an efficient way to alternate rendering between lets say a main menu, options menu, and "in the game." The only two ways I've come up with so far are to have 1 render function, with code for each part (menu, ...) and a variable to control what gets drawn, or to have multiple render functions, and use a function pointer to point to the appropriate one, and then just call the function pointer. I always wonder how more professional games do it.

• Changing the context of a self-executing function

  - by TaylorMac

  This code is copied directly from: http://www.bennadel.com/blog/2264-Changing-The-Execution-Context-Of-Your-Self-Executing-Function-Blocks-In-JavaScript.htm // Set the singleton value to the return value of the self- // executing function block. var singleton = (function(){ // Declare a private variable. var message = "Stop playing with your context!"; this.getMessage = function(){ return( message ); }; // Return this object reference. return( this ); }).call( {} ); // alert the singleton message. alert( "Message:", singleton.getMessage()); ?My thought is that I can use this to better contain the variables and functions in my programs. However, when I try to run the code in a JSfiddle: http://jsfiddle.net/xSKHh/ It does not return the message. What am I missing?

• how to make a simple database app in android?

  - by Iakovl

  i am not an android developer, prefer C# but i want to play with andorid a bit since i have a android device, apologize in advance for it. i want to make a simple app in android with the basic CRUD functions (create, read, update and delete) while the basic option is to use SQLiteOpenHelper i've seen DAO generators (like greenDAO) that make life more simple as i see it. so the first question is what DAOgenerator to use (if it all)? next is how to properly show it, while i know i need listview i still don't figure out exactly how to bind the database to it and to the querys i'll make for proper display each time i make a new query from a "search" screen, to the main "list display" screen

• MySQL pivot tables - covert rows to columns

  - by user2723490

  This is the structure of my table: Then I run a query SELECT `date`,`index_name`,`results` FROM `mst_ind` WHERE `index_name` IN ('MSCI EAFE Mid NR USD', 'Alerian MLP PR USD') AND `time_period`='M1' and get a table like How can I convert "index_name" rows to columns like: date | MSCI EAFE Mid NR USD | Alerian MLP PR USD etc In other words I need each column to represent an index and rows to represent date-result. I understand that MySQL doesn't have pivot table functions. What is the easiest way of doing this? I've tried this code, but it generates an error: SELECT `date`, MAX(IF(index_name = 'Alerian MLP PR USD' AND `time_period`='M1', results, NULL)) AS res1, MAX(IF(index_name = 'MSCI EAFE Mid NR USD' AND `time_period`='M1', results, NULL)) AS res2 FROM `mst_ind` GROUP BY `date I need to make the conversion on the query level - not PHP. Please suggest a nice and elegant solution. Thanks!

• Can jquery capture the dynamic dom events and perform actions

  - by Zombie15

• C# Get/Set Syntax Usage

  - by RoR

  These are declarations for a Person class. protected int ID { get; set; } protected string Title { get; set; } protected string Description { get; set; } protected TimeSpan jobLength { get; set; } How do I go about using the get/set? In main, I instantiate a Person Tom = new Person(); How does Tom.set/get?? I am use to doing C++ style where you just write out the int getAge() and void setAge() functions. But in C# there are shortcuts handling get and set?

• lua function as argument in C

  - by Nil

  I'm going to pass a function to another function which should operate with the passed function. For example: handler(fun1("foo",2)) handler(fun2(1e-10)) The handler is something like calling the passed function many times. I'm going to bind handler, fun1, fun2 to C-functions. fun1 and fun2 are going to return some user data with a pointer to some cpp-class so that I can further recover which function was it. The problem now is that fun1 and fun2 are going to be called before passed to handler. But I don't need this, what I need is the kind of function and its parameters. However, I should be able to call fun1 and fun2 alone without handler: fun1("bar",3) fun2(1e-5) Is it possible to get the context the function is called from? While typing the question, I realized I could do following handler(fun1, "foo",2); handler(fun2, 1e-10);

• Implementing an iterator over binary tree using C++ 11

  - by user1459339

  I would like to create an iterator over the binary tree so as to be able to use range-based for loop. I understand I ought to implement the begin() and end() function first. Begin should probably point to the root. According to the specification, however, the end() functions returns "the element following the last valid element". Which element (node) is that? Would it not be illegal to point to some "invalid" place? The other thing is the operator++. What is the best way to return "next" element in tree? I just need some advice to begin with this programming.

• How do I write a bash script to replace words in files and then rename files?

  - by Jason

  Hi All, I have a folder structure, as shown below: I need to create a bash script that does 4 things: It searches all the files in the generic directory and finds the string 'generic' and makes it into 'something' As above, but changes "GENERIC" to "SOMETHING" As above, but changes "Generic" to "Something" Renames any filename that has "generic" in it with "something" Right now I am doing this process manually by using the search and replace in net beans. I dont know much about bash scripting, but i'm sure this can be done. I'm thinking of something that I would run and it would take "Something" as the input. Where would I start? what functions should I use? overall guidance would be great. thanks. I am using Ubuntu 10.5 desktop edition.

• C++: How to design a utility class?

  Hi, The title says it all. But I don't know if I should go for static methods, just a header, a class, or something else? What would be best practice? But, I don't want to have an instance of a utility class. I want to add functions like: Uint32 MapRGB (int r, int g, int b); const char* CopyString(const char* char); // etc. You know: utility methods...

• Why is casting and comparing in PHP faster than is_*?

  - by tstenner

  While optimizing a function in PHP, I changed if(is_array($obj)) foreach($obj as $key=$value { [snip] } else if(is_object($obj)) foreach($obj as $key=$value { [snip] } to if($obj == (array) $obj) foreach($obj as $key=$value { [snip] } else if($obj == (obj) $obj) foreach($obj as $key=$value { [snip] } After learning about ===, I changed that to if($obj === (array) $obj) foreach($obj as $key=$value { [snip] } else if($obj === (obj) $obj) foreach($obj as $key=$value { [snip] } Changing each test from is_* to casting resulted in a major speedup (30%). I understand that === is faster than == as no coercion has to be done, but why is casting the variable so much faster than calling any of the is_*-functions?

  I have an array of timestamps referring to the days when a holiday home is booked. each timestamp is a round day. I want to turn this into an array of 'begins' and 'ends' pairs for consecutive dates Are there any php functions I should be aware of for writing this function? Or does anyone have any pointers for this kind of thing? thanks! edit: example array: Array ( [0] => 1273536000 [1] => 1273622400 [2] => 1273708800 [3] => 1273795200 [4] => 1273881600 [5] => 1273968000 [6] => 1274054400 [7] => 1274140800 [8] => 1274227200 ) where a day = 86400 (seconds)

• Check if IsCallback on Application_BeginRequest

  - by user136405

  I have a web application (.NET 3.5) that has this code in Global.asax: Sub Application_BeginRequest(ByVal sender As Object, ByVal e As EventArgs) LinkLoader() PathRewriter() PathAppender() End Sub I want all those functions inside to get called except for when it's an AJAX call back. So, ideally I would have it changed to: Sub Application_BeginRequest(ByVal sender As Object, ByVal e As EventArgs) If not Page.IsCallback then LinkLoader() PathRewriter() PathAppender() End If End Sub But there is not access to the page object here. So, basically my question is: How do I check if the request is an AJAX call back inside Application_BeginRequest? Thank you very much for any feedback.
