问题 I developed a DLL in Managed C++ which loads some plugins (implemented in any .NET language) at runtime using System.Reflection.Assembly.LoadFile. The interface which is implemented by all plugins is implemented in C#. It's used by the Managed C++ code like this: #using <IMyPluginInterface.dll> // Make the 'IMyPluginInterface' type available ref class PluginManager { List<IMyPluginInterface ^> ^m_plugins; // Load all plugins in a well-known directory. void load() { for ( string dllFile in

问题 Every morning I have a report that generates a CSV file that contains names of computers, as well as additional comments throughout the file. Each line that is a comment starts with "#", and comments are scattered throughout the document, not just at the start of the document so I can't just read over the first couple lines. Is there any way to search through the CSV file and delete lines that start with "#"? Or is there a way to select lines that don't start with "#", and save them to as a

问题 I am wanting to search more than column from one database with PHP and MySQL. Currently I have this working. This is my form: <form action="products.php" method="POST"> Search: <input type="text" name="search" /> <input type="submit" value="submit"/> </form> and here is my current working query: $query = "SELECT * FROM `GraphicsCards` WHERE `Brand` LIKE '%". $search . "%'"; $run = mysqli_query ($connection, $query); As you can see my query is searching my database to see if the user search

问题 Before I start, here is the sample format of the database: id date title content -------------------------------------------------------------- 1 YYYY-MM-DD some text here lots of stuff to search here 2 YYYY-MM-DD some text here lots of stuff to search here 3 YYYY-MM-DD some text here lots of stuff to search here I currently have something set up to get the id of a row, then assign the date, title, and content to PHP variables to display in different places on a page (it's a blog, these are

问题 Basically: I have a page with a textbox, and a <ul> list below it. The <ul> is populated by a list of the user's friends. The user begins typing in the name of a friend in the textbox, e.g pressing 'r' I want to immediately update the <ul> with each keypress to show only those friends whose names begin with R, e.g 'Richard, Redmond, Raheem', etc. As the user types more, I want to further restrict the names, e.g if user types 'Ri' then I only want 'Richard' in the list. I'm looking for ideas

问题 Are there any easy ways to implement filtering a user's input (possibly a question) by extracting the meaningful data in the query? I basically want to filter out any noise words so I can send a 'clean' query to Google's search api. 回答1: Um, won't Google do this for you? Send all those dirty, filthy words to Google and let them clean them up for you. 回答2: Jeff talked about "stop words" in one of the previous stackoverflow podcasts. You might try searching for that phrase on google. The

问题 This question is philosophically similar to a question that's come up time and time again here: Search and replace text in all files of a linux directory How to search-replace content within files in Ubuntu Linux? Linux search and replace a complex string But they (with the exception of the last one) all deal with simple replacements. I have a somewhat large block of code which appears in many files (I wish copy/pasting source code was punishable by law), and I need to replace it. Is there

问题 I want to highlight found words in text, for example, as shown here. As far as I know I must follow these steps: 1) In my model, I must add :stored => true option to the field which I want to highlight: searchable do text :title, :stored => true text :description end 2) In my controller, I have to declare which field I want highlighted: def search @search = Article.search do keywords params[:search] do highlight :title end end end 3) In the view I'm not sure what to do, I tried this: -
