  • Implement F3 Find Next using TFindDialog

    - by Pieter van Wyk
    Hi I've implemented a search using the TFindDialog on my form. Everything works well except that I cannot find a way to mimic the "F3 - Find Next" behaviour as in Notepad. Once you have entered a search string, pressing F3 finds the next instance without opening the search dialog. Regards, Pieter.

  • OpenGL 2D Depth Perception

    - by Stephen James
    This is the first time i have ever commented on a forum about programming, so sorry if I'm not specific enough. Here's my problem: I have a 2D RPG game written in Java using LWJGL. All works fine, but at the moment I'm having trouble deciding what the best way to do depth perception is. So , for example, if the player goes in front of the tree/enemy (lower than the objects y-coordinate) then show the player in front), if the player goes behind the tree/enemy (higher than the objects specific y-coordinate), then show the player behind the object. I have tried writing a block of code to deal with this, and it works quite well for the trees, but not for the enemies yet. Is there a simpler way of doing this in LWJGL that I'm missing? Thanks :)

  • Lucene.Net PrefixQuery

    - by Sole
    Hi, i´m development a suggest box for my site search service. I has to search fields like these: Visual Basic Enterprise Edition Visual C++ Visual J++ My code is: Directory dir = Lucene.Net.Store.FSDirectory.GetDirectory("Index", false); IndexSearcher searcher = new Lucene.Net.Search.IndexSearcher( dir,true); Term term = new Term("nombreAnalizado", _que); PrefixQuery query = new PrefixQuery(term); TopDocs topDocs = searcher.Search(query, 10000); This code works well in this case: "Enterprise" will match "Visual Basic Enterprise Edition" But "Enterprise E" doesn´t match anything. I removed white spaces at indexing time and when the user is searching. Thanks.

  • Can I have a macro run whenever I save a file in Visual Studio 2005?

    - by Mark
    When I save a file in Visual Studio 2005, I'd like to have a macro also run that updates a copyright (through a regular expression search and replace). I'm not new to regular expressions, but I am new to VB/VBA and Visual Studio macros, so what I need help with specifically is: getting a macro to run upon save, preferably after I press CTRL-S but before it actually writes the file so that the results of the search and replace are actually saved without having to save twice calling search and replace for a regular expression from inside the VB/VBA macro Thanks, Mark

I'm looking for a simple answer or some keywords to use for searching on Google.

  • Programming in the United States Airforce - How hard to get a job doing it? [closed]

    - by Holland
    I already know how to program. Been at it for a year; the language I've worked mostly with has been C++, and I'm currently studying x86 assembly programming, with the goal to move towards ARM assembly after I've finished with that. Thus, given my experience and knowledge, I'm curious to know if any "vets" around here have had any excursions in the military doing software/electrical engineering, and how hard it would be to actually get a job doing it - with someone who already has previous experience and knowledge regarding that field, however slight. By definition of "hard", in this context, I suppose I'd be referring to the required knowledge to actually be a "shoe-in" for both low level and high level software/hardware applications. I know hex fairly well, and enough to convert that hex to binary. I also have an ok knowledge of algorithms, such as Binary Search Tree, Linked List, etc. Everything I've learned so far has been self taught for the most part.

  • Ldap query returns null result when deployed.

    - by Trey Carroll
    I'm using a very simple Ldap query in my asp.net mvc 2.0 site: String ldapPath = ConfigReader.LdapPath; String emailAddress = null; try { DirectorySearcher search = new DirectorySearcher(ConfigReader.LdapPath); search.Filter = String.Format("(&(objectClass=user)(objectCategory=person)(objectSid={0})) ", securityIdentifierValue); // add the mail property to the list of props to retrieve search.PropertiesToLoad.Add("mail"); var result = search.FindOne(); if (result == null) { throw new Exception("Ldap Query with filter:" + search.Filter.ToString() + " returned a null value (no match found)"); } else { emailAddress = result.Properties["mail"][0].ToString(); } } catch (ArgumentOutOfRangeException aoorEx) { throw new Exception( "The query could not find an email for this user."); } catch (Exception ex) { //_log.Error(string.Format("======!!!!!! ERROR ERROR ERROR !!!!! in LdapLookupUtil.cs getEmailFromLdap Exception: {0}", ex)); throw ex; } return emailAddress; It works fine on my localhost machine. It works fine when I run it in VS2010 on the server. It always returns a null result when deployed. Here is my web.config: Asp.Net Configuration option in Visual Studio. A full list of settings and comments can be found in machine.config.comments usually located in \Windows\Microsoft.Net\Framework\v2.x\Config -- section enables configuration of the security authentication mode used by ASP.NET to identify an incoming user. -- <!-- -- section enables configuration of what to do if/when an unhandled error occurs during the execution of a request. Specifically, it enables developers to configure html error pages to be displayed in place of a error stack trace. -- I'm running it under the default app pool. Does anybody see the problem? This is driving me crazy!

  • Yii - Custom GridView with Multiple Tables

    - by savinger
    So, I've extended GridView to include an Advanced Search feature tailored to the needs of my organization. Filter - lets you show/hide columns in the table, and you can also reorder columns by dragging the little drag icon to the left of each item. Sort - Allows for the selection of multiple columns, specify Ascending or Descending. Search - Select your column and insert search parameters. Operators tailored to data type of selected column. Version 1 works, albeit slowly. Basically, I had my hands in the inner workings of CGridView, where I snatch the results from the DataProvider and do the searching and sorting in PHP before rendering the table contents. Now writing Version 2, where I aim to focus on clever CDbCriteria creation, allowing MySQL to do the heavy lifting so it will run quicker. The implementation is trivial when dealing with a single database table. The difficulty arises when I'm dealing with 2 or more tables... For example, if the user intends to search on a field that is a STAT relation, I need that relation to be present in my query. Here's the question. How do I assure that Yii includes all with relations in my query so that I include comparisons? I've included all my relations with my criteria in the model's search function and I've tried CDbCriteria's together ... public function search() { $criteria=new CDbCriteria; $criteria->compare('id', $this->id); $criteria->compare( ... ... $criteria->with = array('relation1','relation2','relation3'); $criteria->together = true; return new CActiveDataProvider( get_class($this), array( 'criteria'=>$criteria, 'pagination' => array('pageSize' => 50) ));} But I still get errors like this... CDbCommand failed to execute the SQL statement: SQLSTATE[42S22]: Column not found: 1054 Unknown column 't.relation3' in 'where clause'. The SQL statement executed was: SELECT COUNT(DISTINCT `t`.`id`) FROM `table` `t` LEFT OUTER JOIN `relation_table` `relation0` ON (`t`.`id`=`relation0`.`id`) LEFT OUTER JOIN `relation_table` `relation1` ON (`t`.`id`=`relation1`.`id`) WHERE (`t`.`relation3` < 1234567890) Where relation0 and relation1 are BELONGS_TO relations, but any STAT relations are missing. Furthermore, why is the query a SELECT COUNT(DISTINCT 't'.'id') ?

  • How to incorporate existing open source software from a licensing perspective?

    - by Matt
    I'm working on software that uses the following libraries: Biopython SciPy NumPy All of the above have licenses similar to MIT or BSD. Three scenarios: First, if I don't redistribute those dependencies, and only my code, then all I need is my own copyright and license (planing on using the MIT License) for my code. Correct? What if I use py2exe or py2app to create a binary executable to distribute so as to make it easy for people to run the application without needing to install python and all the dependencies. Of course this also means that my binary file(s) contains python itself (along with any other packages I might have performed a pip install xyz). What if I bundle Biopython, SciPy, and NumPy binaries in my package? In the latter two cases, what do I need to do to comply with copyright laws.

  • Doing "it all from scratch" is different than OS-specifics

    - by Bigyellow Bastion
    Many people tell me that in order to write my own operating system I need to understand the inner-workings of the one I'll be writing it on. That's nonsense. I mean I understand it for education purposes, such as studying the workings of a current OS to gain better knowledge of writing one myself. But the OS I'm writing it on is nothing but my scratchpad offering me software to write the code in, and software to assemble/compile my code into executable instructions. I've been told that I need to decide which OS I'm writing it on before I write it, but all I need is an assembler to produce flat binary, or a compiler to produce object code and a linker to link it into a flat binary .bin file. Why do people say it matters which OS you make an OS on, when it doesn't?

  • Adding new events to be handled by script part without recompilation of c++ source code

    - by paul424
    As in title I want to write an Event system with handling methods written in external script language, that is Angelscript. The AS methods would have acess to game's world modifing API ( which has to be regsitered for Angelscript Machine as the game starts) . I have come to this problem : if we use the Angelsript for rapid prototyping of the game's world behavior , we would like to be able to define new Event Types, without recompiling the main binary. Is that ever possible , don't stick to Angelscript, I think about any possible scripting language. The main thought is this : If there's some really new Event possible to be constructed , we must monitor some information coming from the binary, for example some variable value changing and the Events are just triggered on some conditions on those changes , wer might be monitoring the Creatures HP, by having a function call on each change, there we could define new Events such as Creature hurt, creature killed, creature healed , creature killed and tormented to pieces ( like geting HP very much below 0 ) . Are there any other ideas of constructing new Events at the scripting side ?

  • Learning about C Bitshift Operators

    - by Chris Hammond
    So I was doing some reading tonight on my Nerdkit , I had planned to actually do some playing around with it, but decided just to read a bit. I’ve never coded in C, I did C++ in College (not very well) and do most of my development in C# these days (when I’m doing code, mostly for fun). While all similar, there are a few differences, so doing things in C is a learning experience. There was some practice questions for AND and OR using Binary. Here are some examples. When comparing binary with AND ...(read more)

    Let's say I have the following model: Person <AR def name [self.first_name,self.middle_name,self.last_name].select{|n| n.present?}.join(' ') end end How could I do a search on the virtual attribute with searchlogic, something like: Person.search.name_like 'foo' Of courese I could construct a large statement like: Person.search.first_name_like_or_last_name_like_or_... 'argh' but surely there is a more elegant way.

  • How do I get apache RewriteRule working correctly for a subdomain?

    - by mike
    I just setup a subdomain with the following RewriteCond: RewriteCond $1 !^search.php$ RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^/?([^/]+)$ search.php?q=$1 [L,NS] I'm using the same rewrite condition on my main domain and it works perfectly. However, when I set it up on the subdomain, it simply outputs "index.php" when going to http://sub.domain.com Every page on the subdomain outputs the page name in the body instead of processing the code, except for the search page, which appears to be working correctly. What can I do to correct this issue?

  • How can I create a temporary sandbox to compile from source?

    - by zoopp
    I want to follow the steps found here in order to run League of Legends under Ubuntu. According to the guide, I have to compile wine from source because it needs some patches. Compiling from source involves downloading quite a few dependency packages which I don't want to get mixed with the system and thus I'm wondering if there's a way to somehow isolate the whole "download dependencies packages and compile" process as I am only interested in the final wine binary. By isolating the compile process I can just copy the resulting binary and do a simple delete on the sandbox whereas doing it the naive way would require a more complex cleanup.

  • Finding the lowest average Hamming distance when the order of the strings matter

    - by user1049697
    I have a sequence of binary strings that I want to find a match for among a set of longer sequences of binary strings. A match means that the compared sequence gives the lowest average Hamming distance when all elements in the shorter sequence have been matched against a sequence in one of the longer sets. Let me try to explain with an example. I have a set of video frames that have been hashed using a perceptual hashing algorithm so that the video frames that look the same has roughly the same hash. I want to match a short video clip against a set of longer videos, to see if the clip is contained in one of these. This means that I need to find out where the sequence of the hashed frames in the short video has the lowest average Hamming distance when compared with the long videos. The short video is the sub strings Sub1, Sub2 and Sub3, and I want to match them against the hashes of the long videos in Src. The clue here is that the strings need to match in the specific order that they are given in, e.g. that Sub1 always has to match the element before Sub2, and Sub2 always has to match the element before Sub3. In this example it would map thusly: Sub1-Src3, Sub2-Src4 and Sub3-Src5. So the question is this: is there an algorithm for finding the lowest average Hamming distance when the order of the elements compared matter? The naïve approach to compare the substring sequence to every source string won't cut it of course, so I need something that preferably can match a (much) shorter sub string to a set of million of elements. I have looked at MVP-trees, BK-trees and similar, but everything seems to only take into account one binary string and not a sequence of them. Sub1: 100111011111011101 Sub2: 110111000010010100 Sub3: 111111010110101101 Src1: 001011010001010110 Src2: 010111101000111001 Src3: 101111001110011101 Src4: 010111100011010101 Src5: 001111010110111101 Src6: 101011111111010101 I have added a calculation of the examples below. (The Hamming distances aren't correct, but it doesn't matter) **Run 1.** dist(Sub1, Src1) = 8 dist(Sub2, Src2) = 10 dist(Sub3, Src3) = 12 average = 10 **Run 2.** dist(Sub1, Src2) = 10 dist(Sub2, Src3) = 12 dist(Sub3, Src4) = 10 average = 11 **Run 3.** dist(Sub1, Src3) = 7 dist(Sub2, Src4) = 6 dist(Sub3, Src5) = 10 average = 8 **Run 4.** dist(Sub1, Src3) = 10 dist(Sub2, Src4) = 4 dist(Sub3, Src5) = 2 average = 5 So the winner here is sequence 4 with an average distance of 5.

  • ASP.NET Model Binder and base type

    - by user137348
    My model inherits from an interface: public interface IGrid { ISearchExpression Search { get; set; } . . } public interface ISearchExpression { IRelationPredicateBucket Get(); } The model: public class Project : IGrid { public ISearchExpression Search { get; set; } public Project() { this.Search = new ProjectSearch(); } } The ProjectSearch: public class ProjectSearch: ISearchExpression { public string Name { get; set; } public string Number { get; set; } public IRelationPredicateBucket Get() {...} } And the strong typed partialview in the main view: <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<ProjectSearch>" %> <%= Html.TextBoxFor(x=>x.Name)%> <%= Html.TextBoxFor(x => x.Number)%> .... When I submit the form, the Search property don't get bound properly. Everything is empty.The action takes an argument of ProjectSearch type. Why the Search don't get bound as supposed ?
