• Wondering where to begin

  - by Cat

  Hello all. After being interested for years and years (and years), I have finally decided to start learning how to create software and web applications. Base on recommendations, I have started with learning the basics of web design first (which I am almost done with) and then will move on to the meat of my process: learning the languages. Problem is, I don't know where to start :/ PHP, Ruby, Perl...and where would SQL, JavaScript and .NET fit into the mix? I am assuming they build on each other/play off of each other somewhat so following some sort of 'order' will make the process more logical and digestible. You're probably thinking, "Just go to school for computer engineering, duh!" But I already have a degree and don't plan on going back to school. I believe I have an adequate aptitude for this sort of thing, and although it will be challenging, with the support of the community I know I can do it on my own. Thank in advance everyone and I am very sorry for the length. I look forward to hearing what all you have to say. Warm Regards, Cat

• UISlider how to set the initial value

  - by slim

  I'm pretty new at this iphone dev stuff and i'm working on some existing code at a company. The uislider i'm trying to set the initial value on is actually in a UITableViewCell and is a custom control. I was thinking in the cell init cell = (QuantitiesCell *)[self loadCellWithNibName:@"QuantitiesCell" forTableView:ltableView withStyle:UITableViewCellStyleDefault]; i could just call something like ((QuantitiesCell *)cell).value = 5; The actual QuantitiesCell class has the member value and the following functions -(void)initCell;{ if (listOfValues == nil) { [self initListOfValues]; } quantitiesSLider.maximumValue = [listOfValues count]-1; quantitiesSLider.minimumValue = 0; quantitiesSLider.value = self.value; } -(void)initListOfValues;{ listOfValues = [[NSMutableArray alloc] initWithCapacity:10]; int j =0; for (float i = minValue; i <= maxValue+increment; i=i+increment) { [listOfValues addObject:[NSNumber numberWithFloat: i]]; if (i == value) { quantitiesSLider.value = j; } j++; } } like i said, i'm pretty new at this so if i need to post more of the code to show whats going to get help, let me know, This slider always is defaulting to 1, the slider ranges usually from 1-10, and i want to set it to a specific value of the item i'm trying to edit.

• Best strategy for synching data in iPhone app

  - by iamj4de

  I am working on a regular iPhone app which pulls data from a server (XML, JSON, etc...), and I'm wondering what is the best way to implement synching data. Criteria are speed (less network data exchange), robustness (data recovery in case update fails), offline access and flexibility (adaptable when the structure of the database changes slightly, like a new column). I know it varies from app to app, but can you guys share some of your strategy/experience? For me, I'm thinking of something like this: 1) Store Last Modified Date in iPhone 2) Upon launching, send a message like getNewData.php?lastModifiedDate=... 3) Server will process and send back only modified data from last time. 4) This data is formatted as so: <+><data id="..."></data></+> // add this to SQLite/CoreData <-><data id="..."></data></-> // remove this <%><data id="..."><attribute>newValue</attribute></data></%> // new modified value I don't want to make <+, <-, <%... for each attribute as well, because it would be too complicated, so probably when receive a <% field, I would just remove the data with the specified id and then add it again (assuming id here is not some automatically auto-incremented field). 5) Once everything is downloaded and updated, I will update the Last Modified Date field. The main problem with this strategy is: If the network goes down when I am updating something = the Last Modified Date is not yet updated = next time I relaunch the app, I will have to go through the same thing again. Not to mention potential inconsistent data. If I use a temporary table for update and make the whole thing atomic, it would work, but then again, if the update is too long (lots of data change), the user has to wait a long time until new data is available. Should I use Last-Modified-Date for each of the data field and update data gradually?

• How to display my server's current response time to an average user

  - by Jason

  Sorry, I'm not really sure of the right way to ask this one so bear with me... We have a web application that runs on a set of servers at a data center (not in our offices) We want to be able to somehow 'advertise' to our clients/users that the availability or response time of our servers has met a standard throughout the day. I am being asked to come up with a standard metric that we can easily advertise on our login screen that shows current "standard response time" checked every x minutes. My thinking is that I need to capture something like the results of a traceroute from a server (either in our office, amazon, etc..) to one of the data center servers and come up with a Red/Yellow/Green type of a notifier for the login screen to let the user know that our tests are responding normally and if they are having delay issues it could be their network or connection to the internet. We have lots of clients in rural areas that have poor connectivity and we are trying to let them know any slowness might be on their end, not ours. I've got the LAMP stack to work with, but this could also be some other system all together as long as it can update the main server with the results. I already have pingdom reports that are available, but that's a bit more than people want to read sometimes. Any ideas on what I can do?

• Using Javascript to expand DIVs and go to anchor text

  - by radiantjoy

  I apologize that this question is so similar to "How can you check for a #hash in a URL using JavaScript?" but would appreciate your help with the following. I would like to use Javascript to display text that is a) identified by an anchor. b) contained within 2 collapsed DIVs....ONLY WHEN the anchor is in the URL. Otherwise, the page should display with all DIVs collapsed. Something like this: if (theHashIsABC) { Expand 2 DIVs on the page and go to the anchor; } else { just display the page; } Specifics: 1. Using IE7 2. DIVs ids to be expanded '8589' and '6212' out of several DIVs on the page 3. Anchor name is anchorABC I have been told that it is not possible to expand some DIVs in IE7 so I am thinking I need to expand all DIVs on the page. [ I can expand just the 2 with a link within the page: <a class="jumplink" href="javascript:toggleBlock('6212');toggleBlock('8589')";link to expand DIVs</a> ] This is what I have so far (in head section)... if(window.location.hash = "anchorABC") { //this works with a button on the page that expand all divs function showAll(pstrClass) { var aElts = document.getElementsByTagName('div'); setDisplay(pstrClass, aElts, 'show', 'Block'); aElts = document.getElementsByTagName('span'); setDisplay(pstrClass, aElts, 'show', 'Inline'); //would also like the page to move to the anchor } else { // just display the page } In advance, thank you for your time.

• RichEdit VCL and URLs. Workarounds for OnPaint Issues.

  - by HX_unbanned

  So, issue is with the thing Delphi progies scare to death - Rich Edit in Windows ( XP and pre-XP versions ). Situation: I have added EM_AUTOURLDETECTION in OnCreate of form. Target - RichEdit1. Then, I have form, that is "collapsed" after showing form. RichEdit Control is sattic, visible and enabled, but it is "hidden" because form window is collapsed. I can expand and collapse form, using Button1 and changing forms Constraints and Size properties. After first time I expand form, the URL inside RichEdit1 control is highlighted. BUT - After second, third, fourth, etc... time I Collapse and Expand form, the RichEdit1 Control does not highlight URL anymore. I have tried EM_SETTEXTMODE messages, also WM_UPDATEUISTATE, also basic WM_TEXT message - no luck. It sems like this merssage really works ( enables detection ) while sending keyboard strokes ( virtual keycodes ), but not when text has been modified. Also - I am thinking to rewrite code to make RichEdit Control dynamic. Would this fix the problem? Maybe solution is to override OnPaint / OnDraw method to avoid highlight ( formatting ) losing when collapsing or expanding form? Weird is that my Embarcadero Documentation says this function must work in any moment text has been modified. Why it does not work? Any help appreciated. I am making this Community Wiki because this is common problem and togewther we cam find solution, right? :) Also - follow-ups and related Question: http://stackoverflow.com/questions/738694/override-onpaint http://stackoverflow.com/questions/478071/how-to-autodetect-urls-in-richedit-2-0 http://www.vbforums.com/archive/index.php/t-59959.html

• Read from one large file and write to many (tens, hundreds, or thousands) files in Java?

  - by Rudiger

  I have a large-ish file (4-5 GB compressed) of small messages that I wish to parse into approximately 6,000 files by message type. Messages are small; anywhere from 5 to 50 bytes depending on the type. Each message starts with a fixed-size type field (a 6-byte key). If I read a message of type '000001', I want to write append its payload to 000001.dat, etc. The input file contains a mixture of messages; I want N homogeneous output files, where each output file contains only the messages of a given type. What's an efficient a fast way of writing these messages to so many individual files? I'd like to use as much memory and processing power to get it done as fast as possible. I can write compressed or uncompressed files to the disk. I'm thinking of using a hashmap with a message type key and an outputstream value, but I'm sure there's a better way to do it. Thanks!

• tips for fixing bad coding/dev habits ?

  - by dfafa

  i want to become a better coder....so i have decided to sign up for computing science program...maybe a formal education can assist me. i started working on smaller projects to learn but currently i have really bad coding/dev habits which is hindering my productivity as the codebase increases.... i have highlighted them and perhaps someone could make suggestions (or redirect to resources) or a more efficient method. most stuff that i made in the past were web apps. i usually develop with putty + nano...i just love the minimalist feel i use winscp and develop directly on my private web server...too lazy to do it on localhost and upload it later. i dont use subversion control...which one do i need ? sometimes ctrl +z doesn't work well. when i run out of ideas for naming variable, i use swear words instead. i swear a lot when i get stuck....how to deal with anger issue ? my codes look ugly with comments everywhere. would rather use procedural coding finds "thinking" in OO difficult and time consuming i "write first think later". refactors code only if i am getting paid for it. dislikes configuring linux distro, Apache, MySQL, scaling, designing graphics and layouts. does not like writing tests likes working alone. does not like sharing codes. has an econ degree dislikes reading other people's code would rather write it on my own it seems my only true desire is to translate my ideas to a working prototype as fast as possible....it seems like i am very uninterested in the other details...could it be that i am not cut out to be a coder after all ? is going back to study comp sci a bad idea ?

• MySQL INJECTION Solution...

  - by Val

  I have been bothered for so long by the MySQL injections and was thinking of a way to eliminate this problem all together. I have came up with something below hope that many people will find this useful. The only Draw back I can think of this is the partial search: Jo =returns "John" by using the like %% statement. Here is a php solution: <?php function safeQ(){ $search= array('delete','select');//and every keyword... $replace= array(base64_encode('delete'),base64_encode('select')); foreach($_REQUEST as $k=>$v){ str_replace($search, $replace, $v); } } foo(); function html($str){ $search= array(base64_encode('delete'),base64_encode('select')); $replace= array('delete','select');//and every keyword... str_replace($search, $replace, $str); } //example 1 ... ... $result = mysql_fetch_array($query); echo html($result[0]['field_name']); //example 2 $select = 'SELECT * FROM safeQ($_GET['query']) '; //example 3 $insert = 'INSERT INTO .... value(safeQ($_GET['query']))'; ?> I know, I know that you still could inject using 1=1 or any other type of injections... but this I think could solve half of your problem so the right mysql query is executed. So my question is if anyone can find any draw backs on this then please feel free to comment here. PLEASE GIVE AN ANSWER only if you think that this is a very useful solution and no major drawbacks are found OR you think is a bad idea all together...

• How can we best represent the SDLC process as a board game?

  - by Innogetics

  I recently got interested in financial board games and saw how they can be very useful in educating children about certain concepts. It got me thinking whether it was also possible to represent certain aspects of executing a software project via a boardgame and make it fun. Here are a few things that I have come up so far: human resources and tools / techniques are represented as cards. requirements are also represented as cards, which are dealt equally to each player, and the objective is to move all requirement cards through an "SDLC" board (one per player) that represent a series of squares grouped according to phases (design all the way to deployment) the passage of time is represented in a main square board like monopoly, and completing a trip around the board (passing "Go") allows the player to move each of the requirement cards a number of steps through the SDLC board depending on the capability of the resource cards (senior programmer allows one requirement to move two squares in the dev phase, junior programmer only one, etc.) players will start with play money representing the project budget, and at every pass at "Go" is payday. the player is out of the game if he runs out of funds. the main board also has "chance" / "risk" cards, which represent things that can mess up a project. damage is applied at the roll of a die, and chance modifiers depend on whether the user has "bought" tools / techniques. I haven't implemented this idea yet as I'm still looking at more play elements that can make the game more engaging, as well as soliciting for more ideas. I am planning to release this under Creative Commons license but haven't decided on the exact license yet. Any more game play suggestions are welcome. UPDATE: This was posted in BoardGameGeek and there's now an active discussion thread there. http://www.boardgamegeek.com/article/4436694

• Disposing underlying object from finalizer in an immutable object

  - by Juan Luis Soldi

  I'm trying to wrap around Awesomium and make it look to the rest of my code as close as possible to NET's WebBrowser since this is for an existing application that already uses the WebBrowser. In this library, there is a class called JSObject which represents a javascript object. You can get one of this, for instance, by calling the ExecuteJavascriptWithResult method of the WebView class. If you'd call it like myWebView.ExecuteJavascriptWithResult("document", string.Empty).ToObject(), then you'd get a JSObject that represents the document. I'm writing an immutable class (it's only field is a readonly JSObject object) called JSObjectWrap that wraps around JSObject which I want to use as base class for other classes that would emulate .NET classes such as HtmlElement and HtmlDocument. Now, these classes don't implement Dispose, but JSObject does. What I first thought was to call the underlying JSObject's Dispose method in my JSObjectWrap's finalizer (instead of having JSObjectWrap implement Dispose) so that the rest of my code can stay the way it is (instead of having to add using's everywhere and make sure every JSObjectWrap is being properly disposed). But I just realized if more than two JSObjectWrap's have the same underlying JSObject and one of them gets finalized this will mess up the other JSObjectWrap. So now I'm thinking maybe I should keep a static Dictionary of JSObjects and keep count of how many of each of them are being referenced by a JSObjectWrap but this sounds messy and I think could cause major performance issues. Since this sounds to me like a common pattern I wonder if anyone else has a better idea.

• jQuery XML loading and then innerfade effect

  - by Ryan Max

  Hello, I think I can explain myself without code, so for brevity's sake here we go: I am using jquery to pull data from an xml and put it into a ul on the page with each xml entry as a li. This is working great! However, what I am trying to do afterwards is use the innerfade plugin to make a simple animation between each of the li's. It's not working though, as it is still just loading the static list with each item visible (whereas if innerfade was working it would only display the first....then fade into the second, etc) It's not an innerfade problem however, because if I add the list in manually to the page (not injecting it with jquery) then the innerfade works fine. I'm relatively new to DOM scripting, so I think I am missing something here. I'm not quite sure how jQuery sequences everything, and I'm having trouble phrasing my question in a search engine friendly manner so here I am. Is it possible to have jquery pull the data from xml, then inject it into the page, then have innerfade work it's magic? Or am I thinking about this the wrong way? xml code: $.ajax({ type: "GET", url: "xml/playlist.xml", dataType: "xml", success: function(xml) { $(xml).find('song').each(function(){ var name = $(this).attr('title'); var date = $(this).attr('artist'); var message = $(this).attr('path'); $('<li></li>').html('<span id="an_name">'+name+'</span><span id="an_date">'+date+'</span><span id="an_message">'+message+'</span>').appendTo('#anniversary'); }); } }); innerfade code: <script type="text/javascript"> jQuery.noConflict(); jQuery(document).ready( function(){ jQuery('#anniversary').innerfade({ speed: 1000, timeout: 5000, type: 'sequence', }); });

• How to best configure a central repository/multiple central repositories for Mercurial?

  - by Mario

  I am new to Mercurial and trying to figure out if it could replace SVN. Everyone I work with has used SVN, CVS and VSS (shiver), so this could be quite a large change. I have been very interested after reading about its merge and branch capability, but have a few reservations. We are currently on SVN, and have one central repository. From my reading, it seems as though there is no ONE central repository for all projects when using Mercurial. NOTE: We consider each project a separate logical set of code, or a Visual Studio Solution. It runs on its own. We have around 60 separate projects in our one central SVN repository. After reading about Mercurial it seems to me that I have to create 60 separate central repositories for each one of these projects on the server. QUESTION #1: Should I create a single repository for each project? If yes, then I am worried about configuring and hosting 60 separate central Mercurial servers. I started thinking I could configure one file, but it seems as if each repository must be individually configured using the “C:...\MyRepository.hg\hgrc” file (Windows install). It also seems as I have to run 60 servers (hg serve), I would assume on different ports. QUESTION #2: If the answer to question 1 is yes, there should be a single central repository for each project, then how have people managed many multiple repositories? Finally, I haven’t looked into moving all history and changes from one SVN repository to a bunch of separate Mercurial repositories, but would appreciate any comments from someone who has done this (or if it is even possible).

• GUI toolkit for Unicode text app?

  - by wrp

  In developing a tool for processing text in exotic scripts, I'm having trouble choosing a GUI toolkit. The main part of the interface is to be a text editor, not much more elaborate than Notepad, but with its own input method editor. It is to be extensible in a scripting language so that non-programmers can develop their own input methods and display routines. It will be assumed that all files are UTF-8. More elaborate support like regexes is not needed. The main sticking points are: characters beyond the Basic Multilingual Plane right-to-left and bi-directional text extension in a scripting language cross-platform Linux/Windows/OS X My first choice was Tcl/Tk, but it lacks bidi and going beyond the BMP seems dodgy. At the other extreme, I've considered Qt with embedded ECMAScript, but that might be heavier and less malleable than I would like. I'm even thinking about making it browser based, but I'm concerned that the IM for large scripts would be too heavy for client-side processing. I've also looked at a few similar projects in Java, but the quality of the font rendering in SWING has been unacceptable. What are your experiences in handling Unicode with various toolkits? Are there other serious issues I haven't considered? What would you recommend for doing this in the lightest way?

• Pointer Implementation Details in C

  - by Will Bickford

  I would like to know architectures which violate the assumptions I've listed below. Also I would like to know if any of the assumptions are false for all architectures (i.e. if any of them are just completely wrong). sizeof(int *) == sizeof(char *) == sizeof(void *) == sizeof(func_ptr *) The in-memory representation of all pointers for a given architecture is the same regardless of the data type pointed to. The in-memory representation of a pointer is the same as an integer of the same bit length as the architecture. Multiplication and division of pointer data types are only forbidden by the compiler. NOTE: Yes I know this is nonsensical. What I mean is - is there hardware support to forbid this incorrect usage? All pointer values can be casted to a single integer. In other words, what architectures still make use of segments and offsets? Incrementing a pointer is equivalent to adding sizeof(the pointed data type) to the memory address stored by the pointer. If p is an int32* then p+1 is equal to the memory address 4 bytes after p. I'm most used to pointers being used in a contiguous, virtual memory space. For that usage, I can generally get by thinking of them as addresses on a number line. See (http://stackoverflow.com/questions/1350471/pointer-comparison/1350488#1350488).

• Running an existing LINQ query against a dynamic object (DataTable like)

  - by TomTom

  Hello, I am working on a generic OData provider to go against a custom data provider that we have here. Thsi is fully dynamic in that I query the data provider for the table it knows. I have a basic storage structure in place so far based on the OData sample code. My problem is: OData supports queries and expects me to hand in an IQueryable implementation. On the lowe rside, I dont have any query support. Not a joke - the provider returns tables and the WHERE clause is not supported. Performance is not an issue here - the tables are small. It is ok to sort them in the OData provider. My main problem is this. I submit a SQL statement to get out the data of a table. The result is some sort of ADO.NET data reader here. I need to expose an IQueryable implementation for this data to potentially allow later filtering. Any ide ahow to best touch that? .NET 3.5 only (no 4.0 planned for some time). I was seriously thinking of creating dynamic DTO classes for every table (emitting bytecode) so I can use standard LINQ. Right now I am using a dictionary per entry (not too efficient) but I see no real way to filter / sort based on them.

• suggestions for declarative GUI programming in Java

  - by Jason S

  I wonder if there are any suggestions for declarative GUI programming in Java. (I abhor visual-based GUI creator/editor software, but am getting a little tired of manually instantiating JPanels and Boxes and JLabels and JLists etc.) That's my overall question, but I have two specific questions for approaches I'm thinking of taking: JavaFX: is there an example somewhere of a realistic GUI display (e.g. not circles and rectangles, but listboxes and buttons and labels and the like) in JavaFX, which can interface with a Java sourcefile that accesses and updates various elements? Plain Old Swing with something to parse XUL-ish XML: has anyone invented a declarative syntax (like XUL) for XML for use with Java Swing? I suppose it wouldn't be hard to do, to create some code based on STaX which reads an XML file, instantiates a hierarchy of Swing elements, and makes the hierarchy accessible through some kind of object model. But I'd rather use something that's well-known and documented and tested than to try to invent such a thing myself. JGoodies Forms -- not exactly declarative, but kinda close & I've had good luck with JGoodies Binding. But their syntax for Form Layout seems kinda cryptic. edit: lots of great answers here! (& I added #3 above) I'd be especially grateful for hearing any experiences any of you have had with using one of these frameworks for real-world applications. p.s. I did try a few google searches ("java gui declarative"), just didn't quite know what to look for.

• Designing code for a duo Website + AIR desktop App

  - by faB

  I want to use AIR to create an OFFLINE version of a "webapp" kind of website (lots of ajax, front end code). Haven't been much further than the HelloWorld example, I keep wondering: how do you design your code, to maximize code reuse between the website (say in php or Java or .Net), and the AIR app ? Can you actually re-use 100% of the front end code, provided that it is designed to account for the AIR app ? How would you go about doing that ? For example, the website makes many Ajax calls which have latency, and uses listeners. The AIR app doesn't need listeners it could run database requests synchronously, and it doesn't need to run ajax calls right? Would you write an abstraction layer for that ? So that the same calls on the AIR app will not do a xmlhttp but instead implement the server-side code with AIR; and call the listener ? So you don't have to rewrite the front end code patterns ? Does this make sense ? It's really hard to search on Google. I'm thinking there must be a good article somewhere of somebody who went through and perhaps a framework to do that ?

• XSLT inserting once off custom text

  - by BeraCim

  Hi all: The folloiwng is a pre-existing xml file. I was wondering how can I insert a element before the first element using xslt? <XmlFile> <!-- insert another <tag> element here --> <tag> <innerTag> </innerTag> </tag> <tag> <innerTag> </innerTag> </tag> <tag> <innerTag> </innerTag> </tag> </XmlFile> I was thinking of using a for-each loop and test the position = 0, but upon the first occurence of the for-each its already too late. This is a once-off text so I can't combine it with other xslt templates that are already inside the xsl file. Thanks.

• self referencing object in JPA

  - by geoaxis

  Hello, I am trying to save a SystemUser entity in JPA. I also want to save certain things like who created the SystemUser and who last modified the system User as well. @ManyToOne(targetEntity = SystemUser.class) @JoinColumn private SystemUser userWhoCreated; @Temporal(TemporalType.TIMESTAMP) @DateTimeFormat(iso=ISO.DATE_TIME) private Date timeCreated; @ManyToOne(targetEntity = SystemUser.class) @JoinColumn private SystemUser userWhoLastModified; @Temporal(TemporalType.TIMESTAMP) @DateTimeFormat(iso=ISO.DATE_TIME) private Date timeLastModified; I also want to ensure that these values are not null when persisted. So If I use the NotNull JPA annotation, that is easily solved (along with reference to another entity) The problem description is simple, I cannot save rootuser without having rootuser in the system if I am to use a DataLoader class to persist JPA entity. Every other later user can be easily persisted with userWhoModified as the "systemuser" , but systemuser it's self cannot be added in this scheme. Is there a way so persist this first system user (I am thinking with SQL). This is a typical bootstrap (chicken or the egg) problem i suppose.

• Compiler Errors...it ran yesterday!?

  - by howdytest

  This is a pre-existing Java project being run in Eclipse 3.5.2 32 bit.. Day 1: Install Java SE 6 Update 20 JDK. Experience Crash in Eclipse. Install Java 5. Same problem-(uninstall java 5). Re-install Java 6. Install Eclipse 3.3.1. Install Eclipse 3.5.2. 32-bit. No problems. Run Eclipse 3.5.2. 64-bit. No problems. Set up the project, configure, and run. No problems. Day 2: Load Eclipse to start a new project. Previous project now has 940 errors. Error Type is "Java Problem". The project ran 100% without a problem on Day 1. The only thing that happened between Day 1 and Day 2 was restarting my computer. I just tried to recreate the project, step by step, and am still getting the same errors. I know it's not the code -- it was working. Not to mention that it's an opensource project, such a problem would be documented. I'm thinking something is wrong with my Java install. Or, perhaps, it's a 32-bit/64-bit problem. I'm running win7 64bit. So before formatting my window's partition, I thought I'd throw the problem your way to see if anyone knows what's going on. Thanks.

• MS Query Analizer/Management Studio replacement?

  - by kprobst

  I've been using SQL Server since version 6.5 and I've always been a bit amazed at the fact that the tools seem to be targeted to DBAs rather than developers. I liked the simplicity and speed of the Query Analizer for example, but hated the built-in editor, which was really no better than a syntax coloring-capable Notepad. Now that we have Management Studio the management part seems a bit better but from a developer standpoint the tools is even worse. Visual Studio's excellent text editor... without a way to customize keyboard bindings!? Don't get me started on how unusable is the tree-based management hierarchy. Why can't I re-root the tree on a list of stored procs for example the way the Enterprise Manager used to allow? Now I have a treeview that needs to be scrolled horizontally, which makes it eminently useless. The SQL server support in Visual Studio is fantastic for working with stored procedures and functions, but it's terrible as a general ad hoc data query tool. I've tried various tools over the years but invariably they seem to focus on the management side and shortchange the developer in me. I just want something with basic admin capabilities, good keyboard support and requisite DDL functionality (ideally something like the Query Analyzer). At this point I'm seriously thinking of using vim+sqlcmd and a console... I'm that desperate :) Those of you who work day in and day out with SQL Server and Visual Studio... do you find the tools to be adequate? Have you ever wished they were better and if you have found something better, could you share please? Thanks!

• Select * from 'many to many' SQL relationship

  - by Rampant Creative Group

  I'm still learning SQL and my brain is having a hard time with this one. Say I have 3 tables: teams players and teams_players as my link table All I want to do is run a query to get each team and the players on them. I tried this: SELECT * FROM teams INNER JOIN teams_players ON teams.id = teams_players.team_id INNER JOIN players ON teams_players.player_id = players.id But it returned a separate row for each player on each team. Is JOIN the right way to do it or should I be doing something else? ----------------------------------------- Edit Ok, so from what I'm hearing, this isn't necessarily a bad way to do it. I'll just have to group the data by team while I'm doing my loop. I have not yet tried the modified SQL statements provided, but I will today and get back to you. To answer the question about structure - I guess I wasn't thinking about the returned row structure which is part of what lead to my confusion. In this particular case, each team is limited to 4 players (or less) so I guess the structure that would be helpful to me is something like the following: teams.id, teams.name, players.id, players.name, players.id, players.name, players.id, players.name, players.id, players.name, 1 Team ABC 1 Jim 2 Bob 3 Ned 4 Roy 2 Team XYZ 2 Bob 3 Ned 5 Ralph 6 Tom

• URL rewriting to a common end point

  - by sunil

  I want to create an asp.net white-label site http://whitelabel.com, that could be styled for each of our clients according to their specific needs. So for example, client abc would see the site in their corporate colours and be accessed through their specific url http://abc.com. Likewise client xyz would see the site in their own styling and url http://xyz.com. Typing either url, in effect, takes the user to http://whitelabel.com where the styling is applied, and the client's url structure is retained. I was thinking of URL rewriting using URLRewriter.Net (http://urlrewriter.net/), or similar, mapping the incoming address to a client id and applying the theme accordingly. So, a url rewrite rule may be something like <rewrite url="http//abc.com/(.+)" to="~/$1?id=1" /> <rewrite url="http//xyz.com/(.+)" to="~/$1?id=2" /> I could then read the id, map it to the client, and with a bit of jiggery-pokery, apply the correct theme. I was wondering if: this is the right approach ? I've overlooked something ? there is a better way to do this ? Any suggestions would be appreciated.

• Batch Image compression tool for optimizing thousands of images

  - by Daniel Magliola

  Hi all, I'm maintaining a site that has thousands of images that have not been compressed nearly enough. The homepage weighs in at 1.5 Mb currently, and it could easily be way less that half that. I'm looking for some kind of tool that'll take a folder full of JPG pictures and will recompress them to their "optimal" compression value. Obviously, "optimal lossy compression setting" is an oxymoron, but I'm thinking maybe a tool that'll try different levels and compare the outputs to the input, and choose a "sweet spot" between size and destruction? Or even try whether PNG is a better option, many times it is, for "drawing" type stuff. Does anyone of you know any such tool? I'd have lots of fun coding one, but I bet someone already did and will save me 2 days. Alternatively, of course, anything that'll take all pictures in a folder and recompress them with a fixed quality level (say, 40) will also work, it'll just not make my inner nerd as happy, but it'll solve my problem just fine. (Ideally something that can run on Windows, ideally from the command line) Thank you!
