  • C++ Beginner - Trouble using classes inside of classes

    - by Francisco P.
    Hello, I am working on a college project, where I have to implement a simple Scrabble game. I have a player class (containing a Score and the player's hand, in the form of a std::string, and a score class (containing a name and numeric (int) score). One of Player's member-functions is Score getScore(), which returns a Score object for that player. However, I get the following error on compile time: player.h(27) : error C2146: syntax error : missing ';' before identifier 'getScore' player.h(27) : error C4430: missing type specifier - int assumed. Note: C++ does not support default-int player.h(27) : error C4430: missing type specifier - int assumed. Note: C++ does not support default-int player.h(27) : warning C4183: 'getScore': missing return type; assumed to be a member function returning 'int' player.h(35) : error C2146: syntax error : missing ';' before identifier '_score' player.h(35) : error C4430: missing type specifier - int assumed. Note: C++ does not support default-int player.h(35) : error C4430: missing type specifier - int assumed. Note: C++ does not support default-int Here's lines 27 and 35, respectively: Score getScore(); //defined as public (...) Score _score; //defined as private I get that the compiler is having trouble recognizing Score as a valid type... But why? I have correctly included Score.h at the beginning of player.h: #include "Score.h" #include "Deck.h" #include <string> I have a default constructor for Score defined in Score.h: Score(); //score.h //score.cpp Score::Score() { _name = ""; _points = 0; } Any input would be appreciated! Thanks for your time, Francisco EDIT: As requested, score.h and player.h: http://pastebin.com/3JzXP36i http://pastebin.com/y7sGVZ4A

  • Abstract Base Class or Class?

    - by Mohit Deshpande
    For my semester project, my team and I are supposed to make a .jar file (library, not runnable) that contains a game development framework and demonstrate the concepts of OOP. Its supposed to be a FRAMEWORK and another team is supposed to use our framework and vice-versa. So I want to know how we should start. We thought of several approaches: 1. Start with a plain class public class Enemy { public Enemy(int x, int y, int health, int attack, ...) { ... } ... } public class UserDefinedClass extends Enemy { ... } 2. Start with an abstract class that user-defined enemies have to inherit abstract members public abstract class Enemy { public Enemy(int x, int y, int health, int attack, ...) { ... } public abstract void draw(); public abstract void destroy(); ... } public class UserDefinedClass extends Enemy { ... public void draw() { ... } public void destroy() { ... } } 3. Create a super ABC (Abstract Base Class) that ALL inherit from public abstract class VectorEntity { ... } public abstract class Enemy extends VectorEntity { ... } public class Player extends VectorEntity { ... } public class UserDefinedClass extends Enemy { ... } Which should I use? Or is there a better way?

  • iPhone UI addSubview causing concurrency exception

    - by Eli
    This is really odd... I run my app, and while it is opening and the views are constructing I get: Collection <CALayerArray: 0x124650> was mutated while being enumerated. The code trace goes through the following: main UIApplicationMain -[UIApplication _run] CFRunLoopRunInMode CFRunLoopRunSpecific _UIApplicationHandleEvent -[UIApplication sendEvent:] -[UIApplication handleEvent:withNewEvent:] -[UIApplication _runWithURL:sourceBundleID:] -[UIApplication _performInitilizationWithURL:sourceBundleID:] -[AppDelegate applicationDidFinishLaunching:] +[Controller initializeController] //This is my own function [window addSubview: pauseMenuController.view] //This is the last point of my code it goes through -[UIView(Hierarchy) addSubview:] -[UIView(Internal) _addSubview:positioned:relativeTo:] -[UIView(Hierarchy) _makeSubtreePerformSelector:withObject:] -[UIView(Hierarchy) _makeSubtreePerformSelector:withObject:withObject:copySublayers:] -[UIView(Hierarchy) _makeSubtreePerformSelector:withObject:withObject:copySublayers:] _NSFastEnumerationMutationHandler objc_exception_throw I've run the game lots and lots and lots of times and I've never seen this, then suddenly it popped up. The weird thing is that I'm not creating any other threads (that I know of) until after this code all gets called. It'll be easier for me to debug this if someone can give me some explanation of what might be getting modified while it's being accessed in a UIView. Does it have something to do with adding something to the view while it's already adding something, maybe? Any ideas?

  • javascript addEventListener onStateChange not working in IE

    - by user347456
    Hi, I have two colorbox popup boxes which show a youtube video in each. When they're finished playing, I'm trying to have them automatically close the colorbox window. This code below works perfect in firefox, but in IE I can't get addEventListener to work. I've tried attachEvent with no success. Can anybody offer any suggestions as to how to solve this? It seems simple but I'm exhausted trying to find a solution. By the way, this is my first time as stackoverflow and it's very impressive. var params = { allowScriptAccess: "always" }; var atts = { id: "ytplayer1" }; swfobject.embedSWF("http://www.youtube.com/v/VIDEO1&rel=0&hl=en_US&fs=0&autoplay=1&enablejsapi=1&playerapiid=ytvideo1", "popupVideoContainer1", "640", "385", "8", null, null, params, atts); var params2 = { allowScriptAccess: "always" }; var atts2 = { id: "ytplayer2" }; swfobject.embedSWF("http://www.youtube.com/v/VIDEO2&rel=0&hl=en_US&fs=0&autoplay=1&enablejsapi=1&playerapiid=ytvideo2", "popupVideoContainer2", "640", "385", "8", null, null, params2, atts2); function onYouTubePlayerReady(playerId) { if(playerId == 'ytvideo1'){ var ytplayer = document.getElementById('ytplayer1'); ytplayer.addEventListener("onStateChange", "onytplayerStateChange", false); } else if(playerId == 'ytvideo2'){ var ytplayer = document.getElementById("ytplayer2"); //ytplayer.addEventListener("onStateChange", "onytplayerStateChange", false); if (ytplayer.addEventListener) { ytplayer.addEventListener("onStateChange", "onytplayerStateChange", false); } else if (ytplayer.attachEvent) { ytplayer.attachEvent("onStateChange", onytplayerStateChange); } } } function onytplayerStateChange(newState) { if(newState == 0){ $.fn.colorbox.close(); } }

  • Changing JButton background colour temporarily?

    - by sashep
    Hi, I'm super new to Java, and in need of some help. I'm making a little java desktop application where I basically have a grid of 4 JButtons ( 2 x 2 grid), and I need the background colour of individual JButtons to change, and after one second, change back to the original colour (the game I'm trying to make is like Simon, where you have to follow a pattern of buttons that light up). I have a vector that contains randomly generated numbers in the range of 1 to 4, and I want to be able to get each element from the vector and get the corresponding button to change to a different colour for one second (for example, if the vector contains 2 4 1, I would want button 2 to change, then button 4 to change, then button 1 to change). Is this possible or is there a better way to go about doing this with something other than JButtons? How do I implement this? Also, I'm running Mac OS X, which apparently (based on some things I've read on forums) doesn't like JButtons background changing (I think it's because of system look and feel), how can I change this so it works on mac? Thank you in advance for any help :)

  • Using the MVVM Light Toolkit to make Blendable applications

    - by Dave
    A while ago, I posted a question regarding switching between a Blend-authored GUI and a Visual Studio-authored one. I got it to work okay by adding my Blend project to my VS2008 project and then changing the Startup Application and recompiling. This would result in two applications that had completely different GUIs, yet used the exact same ViewModel and Model code. I was pretty happy with that. Now that I've learned about the Laurent Bugnion's MVVM Light Toolkit, I would really like to leverage his efforts to make this process of supporting multiple GUIs for the same backend code possible. The question is, does the toolkit facilate this, or am I stuck doing it my previous way? I've watched his video from MIX10 and have read some of the articles about it online. However, I've yet to see something that indicates that there is a clean way to allow a user to either dynamically switch GUIs on the fly by loading a different DLL. There are MVVM templates for VS2008 and Blend 3, but am I supposed to create both types of projects for my application and then reference specific files from my VS2008 solution? UPDATE I re-read some information on Laurent's site, and seemed to have forgotten that the whole point of the template was to allow the same solution to be opened in VS2008 and Blend. So anyhow, with this new perspective it looks like the templates are actually intended to use a single GUI, most likely designed entirely in Blend (with the convenience of debugging through VS2008), and then be able to use two different ViewModels -- one for design-time, and one for runtime. So it seems to me like the answer to my question is that I want to use a combination of my previous solution, along with the MVVM Light Toolkit. The former will allow me to make multiple, distinct GUIs around my core code, while the latter will make designing fancy GUIs in Blend easier with the usage of a design-time ViewModel. Can anyone comment on this?

    Hello everybody Many weeks ago,I tried to work on a mini project on Android OS requires ZXING, I followed several tutorials on this web site and on other Example: tuto1, and many tags and tutorials here tuto2, tuto3 ... But I failed each time. I can't import the android project into eclipse IDE to compile it with my code "not via Intent zxing APK-and my program like this example : private Button.OnClickListener btScanListener = new Button.OnClickListener() { public void onClick(View v) { Intent intent = new Intent("com.google.zxing.client.android.SCAN"); intent.putExtra("SCAN_MODE", "QR_CODE_MODE"); try { startActivityForResult(intent, REQUEST_SCAN); } catch (ActivityNotFoundException e) { Toast.makeText(Main.this, "Barcode Scanner not intaled ", 2000).show(); } } }; public void onActivityResult(int reqCode, int resCode, Intent intent) { if (REQUEST_SCAN == reqCode) { if (RESULT_OK == resCode) { String contents = intent.getStringExtra("SCAN_RESULT"); Toast.makeText(this, "Succès : " + contents, 2000).show(); } else if (RESULT_CANCELED == resCode) { Toast.makeText(this, "Scan annulé", 2000).show(); } } }` ". I feel disappointed, frustrated and sad. I still have errors after importing the project.

  • Concat LPSTR in C++

    - by Cat Man Do
    Trying to use as basic C++ as I can to build a list of numbers from 1-52 in a random order (deck of cards). Unfortauntely, all my attempts to concat the strings and get a result end in failure. Any suggestions? NOTE: This is not homework it's something I'm using to create a game. // Locals char result[200] = ""; // Result int card[52]; // Array of cards srand(time(0)); // Initialize seed "randomly" // Build for (int i=0; i<52; i++) { card[i] = i; // fill the array in order } // Shuffle cards for (int i=0; i<(52-1); i++) { int r = i + (rand() % (52-i)); int temp = card[i]; card[i] = card[r]; card[r] = temp; } // Build result for (int c=0; c<52; c++) { // Build sprintf(result, "%d", card[c]); // Comma? if ( c < 51 ) { sprintf(result, "%s", ","); } } My end result is always garbled text. Thanks for the help.

  • For commands to check duped/multiple mc's.

    - by Desmond
    Currently I'm working on a platform type game. I have a for loop in place to check weather or not the players feet are touching the ground. I had this; for (i=0; i<5; i++) { //There are 5 floors if (this.feet.hitTest(_root["g"+i])) { _root.mc.groundTouch = true; //triggers the mc falling } } This works fine only if one of the floors exist(IE if floor1 is on the stage, but floor2-5 aren't); So to try and counter it I tried using; for (i=0; i<5; i++) { if (this.feet.hitTest(_root["floor"+i])) { _root.mc.groundTouch = true; //triggers the mc falling } if (!this.feet.hitTest(_root["floor"+i])) { _root.mc.groundTouch = false; } } This obviously doesn't work because in order for it to function properly, _root.mc.feet would have to be touching all 5 instances of "floor". So my question is; How do I get the code to make _root.mc.groundTouch = true if _root.mc.feet is touching any of the floor instances, but make _root.mc.groundTouch = false only if its touching none of the floor instances? I know that if I really wanted to I could do something like if (_root.mc.feet.hitTest(_root.floor1) && !_root.mc.feet.hitTest(_root.floor2) && etc) But to save myself time, and to give myself the ability to add floors without altering more then i<5 to the amount of floors I have, I would prefer a easier method hopefully something to do with for loops. Thank you ahead of time and your help is very much appreciated

  • Catching MediaPlayer Exceptions from WPF MediaElement Control

    - by ScottCate
    I'm playing video in a MediaElement in WPF. It's working 1000's of times, over and over again. Once in a blue moon (like once a week), I get a windows exception (you know the dialog Dr. Watson Crash??) that happens. The MediaElment doesn't expose an error, it just crashes and sits there with an ugly Crash report on the screen. If you "view this report" you can see it is in fact MediaPlayer that has crashed. I know I can disable the crash reports from popping up - but I'm more interested in finding out what's going wrong. I'm not sure how to capture the results of the Dr. Watson capture, but I have the dialog open now if someone has advice on a better way to capture. Here is the opening line of data, that points to my application, then to wmvdecod.dll AppName: ScottApp.exe AppVer: 2.2009.2291.805 AppStamp:4a36c812 ModName: wmvdecod.dll ModVer: 11.0.5721.5145 ModStamp:453711a3 fDebug: 0 Offset: 000cbc88 And from the Win Event Log.

  • Changing a sprites bitmap

    - by numerical25
    As of right now, I am trying to create a tiling effect for a game I am creating. I am using a tilesheet and I am loading the tiles to the sprite like so... this.graphics.beginBitmapFill(tileImage); this.graphics.drawRect(30, 0,tWidth ,tHeight ); var tileImage is the bitMapData. 30 is the Number of pixels to move retangle. then tWidth and tHeight is how big the rectangle is. which is 30x30 This is what I do to change the bitmap when I role over the tile this.graphics.clear(); this.graphics.beginBitmapFill(tileImage); this.graphics.drawRect(60, 0,tWidth ,tHeight ); I clear the sprite canvas. I then rewrite to another position on tileImage. My problem is.... It removes the old tile completely but the new tile positions farther to the right then where the old bitmap appeared. My tile sheet is only 90px wide by 30px height. On top of that, it appears my new tile is drawn behind the old tile. Is there any better way to perfect this. again, all i want is for the bitmap to change colors

  • CCLabelAtlas setString doesn't update label

    - by JonnyFunFun
    Hello! I have a CCLabelAtlas that I have on a layer to display the current score within my game...the problem that I am having with it is that it does not update when I use [scoreLabel setString:]. Here's how I have it laid out: In the header: @interface GameScene : CCLayer { ... CCLabelAtlas* scoreLabel; } And in the init: scoreLabel = [[CCLabelAtlas alloc] initWithString:@"0" charMapFile:@"scoreCharMap.png" itemWidth:6 itemHeight:8 startCharMap:'.']; [scoreLabel setPosition:ccp(105, 414)]; [self addChild:scoreLabel z: 6]; scoreCharMap.png is a custom map that includes ./0123456789 of my desired font. When the score is changed, I attempt to do this to get the label to update with the current score: NSString* str = [[NSString alloc] initWithFormat:@"%d", [[GameRunner sharedInstance] currentScore]]; [scoreLabel setString: str]; [str release]; [scoreLabel draw]; Problem is that it doesn't ever update - it just sits there and displays 0. I know for a fact due to breakpoints and debugging that setString is being called, and that the string that it should be displaying is correct - but it just doesn't update. Hard-coding the value and saying [scoreLabel setString:@"1234"] does nothing, either. What am I doing wrong here? I am using Cocos2d 0.99 - thanks in advance!

  • Why calling Process.killProcess(Process.myPid()) is a bad idea?

    - by Tal Kanel
    I've read some posts saying using this method is "not good", shouldn't been use, it's not the right way to "close" the application and it's not how android works... I understand and accept the fact that Android OS knows better then me when it's the right time to terminate the process, but I didn't heard yet a good explanation why it's wrong using the killProcess() method?. after all - it's part of the android API... what I do know is that calling this method while other threads doing in potential an important work (operations on files, writing to DB, HTTP requests, running services..) can be terminated in the middle, and it's clearly not good. also I know I can benefit from the fact that "re-open" the application will be faster, cause the system maybe still "holds" in memory state from last time been used, and killProcess() prevents that. beside this reason, in assumption I don't have such operations, and I don't care my application will load from scratch each run, there are other reasons why not using the killProcess() method? I know about finish() method to close an Activity, so don't write me about that please.. finish() is only for Activity. not to all application, and I think I know exactly why and when to use it... and another thing - I'm developing also games with the Unity3D framework, and exporting the project to android. when I decompiled the generated apk, I was very suprised to find out that the java source code created from unity - implementing Unity's - Application.quit() method, with Process.killProcess(Process.myPid()). Application.quit() is suppose to be the right way to close game according to Unity3d guides (is it really?? maybe I'm wrong, and missed something), so how it happens that the Unity's framework developers which doing a very good work as it seems implemented this in native android to killProcess()? anyway - I wish to have a "list of reasons" why not using the killProcess() method, so please write down your answer - if you have something interesting to say about that. TIA

  • Developmnet process for an embedded project with significant Hardware change

    - by pierr
    Hi, I have a good idea about Agile development process but it seems it does not fit well with a embedded project with significant hardware change. I will describe below what we are currently doing (Ad-hoc way , no defined process yet). The change are divided to three categories and different process are used for them : complete hardware change example : use a different video codec IP a) Study the new IP b) RTL/FPGA simulation c) Implement the leagcy interface - go to b) d) Wait until hardware (tape out) is ready f) Test on the real Hardware hardware improvement example : enhance the image display quaulity by improving the underlie algorithm a)RTL/FPGA simulation b)Wait until hardware and test on the hardware Mino change exmaple : only change hardware register mapping a)Wait until hardware and test on the hardware The worry is it seems we don't have too much control and confidence about software maturity for the hardware change as the bring up schedule is always very tight and the customer desired a seemless change when updating to a new version hardware. How did you manage this kind of hardware hardware change? Did you solve that by a Hardware Abstraction Layer (HAL)? Did you have a automatical test for the HAL layer? How did you test when the hardware platform is not even ready? Do you have well documented process for this kind of change? Thanks for your insight.

  • What file format can represent an uncompressed raster image at 48 or 64 bits per pixel?

    - by finnw
    I am creating screenshots under Windows and using the LockBits function from GDI+ to extract the pixel data, which will then be written to a file. To maximise performance I am also: Using the same PixelFormat as the source bitmap, to avoid format conversion Using the ImageLockModeUserInputBuf flag to extract the pixel data into a pre-allocated buffer This pre-allocated buffer (pointed to by BitmapData::Scan0) is part of a memory-mapped file (to avoid copying the pixel data again.) I will also be writing the code that reads the file, so I can use (or invent) any format I wish. However I would prefer to use a well-known format that existing programs (ideally web browsers) are able to read, because that means I can visually confirm that the images are correct before writing the code for the other program (that reads the image.) I have implemented this successfully for the PixelFormat32bppRGB format, which matches the format of a 32bpp BMP file, so if I extract the pixel data directly into the memory-mapped BMP file and prefix it with a BMP header I get a valid BMP image file that can be opened in Paint and most browsers. Unfortunately one of the machines I am testing on returns pixels in PixelFormat64bppPARGB format (presumably this is influenced by the video adapter driver) and there is no corresponding BMP pixel format for this. Converting to a 16, 24 or 32bpp BMP format slows the program down considerably (as well as being lossy) so I am looking for a file format that can use this pixel format without conversion, so I can extract directly into the memory-mapped file as I have done with the 32bpp format. What raster image file formats support 48bpp and/or 64bpp?

  • How can I display the users profile pic using the facebook graph api?

    - by kielie
    Hi, I would like to display the users profile picture inside of my applications canvas page, is there a way to do that using the graph api? I know I can do it using FBML but I would also like to pass the profile pic to a flash game I am making, so I would have to get the profile pic from the api and send it as a variable, here is the code I have thus far, $facebook = new Facebook(array( 'appId' => FACEBOOK_APP_ID, 'secret' => FACEBOOK_SECRET_KEY, 'cookie' => true, 'domain' => 'myurl/facebook-test' )); $session = $facebook->getSession(); $uid = $facebook->getUser(); $me = $facebook->api('/me'); $updated = date("l, F j, Y", strtotime($me['updated_time'])); echo "Hello " . $me['name'] . $me['picture'] . "<br />"; echo "<div style=\"background:url(images/bg.jpg); width:760px; height:630px;\">" . "You last updated your profile on " . $updated . "</div>" . "<br /> your uid is" . $uid; Thanx in advance!

  • Uploading to TwitVid using x_verify_credentials_authorization

    - by deepa
    Hi, I am developing an iPhone application that uploads videos to TwitVid using the library TwitVid-iPhone-OAuth3. I have selected this library since Twitter is shifting to OAuth mechanism of authentication. 1) Does this new library allows to upload without user-name and password parameters? 2) I am using the following steps for uploading videos (assumed that new library allows to upload without user-name and password parameters). But, I am getting the error 'Incorrect Signature'. I am not able to identify the mistake that I am doing here. Could you please help me out to solve this problem. Authenticate the app using OAuth (MGTwitterEngine etc) which redirects the user to the web-page asking for log-in and app authentication. If the user authenticates the app, access token will obtained as final step. Upload the video to TwitVid using the following code snippet: OAuth *authorizer = [[OAuth alloc] initWithConsumerKey: @"my_consumer_key" andConsumerSecret: @"my_consumer_secret"]; authorizer.oauth_token = //The key-part of the access token obtained in step 2 authorizer.oauth_token_secret = //The secret-part of the access token obtained in step 2 authorizer.oauth_token_authorized = YES; //Since authenticated in steps 1 and 2 NSString *authHeader = [authorizer oAuthHeaderForMethod: @"POST" andUrl: @"https://api.twitter.com/1/account/verify_credentials.xml" andParams: nil]; twitVid = [[TwitVid alloc] init]; [mTwitVid setDelegate: self]; [mTwitVid authenticateWithXVerifyCredentialsAuthorization: authHeader xAuthServiceProvider: nil]; Thanks and Regards, Deepa

  • Get "term is undefined” error when trying to assign arrayList to List component dataSource

    - by user1814467
    I'm creating an online game where people log in and then have the list of current players displayed. When the user enters a "room" it dispatches an SFSEvent which includes a Room object with the list of users as User objects in that room. As that event's callback function, I get the list of current users which is an Array, switch the View Stack child index, and then I wrap the user list array in an ArrayList before I assign it to the MXML Spark List component's dataSource. Here's my code: My Actionscript Code Section (PreGame.as): private function onRoomJoin(event:SFSEvent):void { const room:Room = this._sfs.getRoomByName(PREGAME_ROOM); this.selectedChild = waitingRoom; /** I know I should be using event listeners * but this is a temporary fix, otherwise * I keep getting null object errors * do to the li_users list not being * created in time for the dataProvider assignment **/ setTimeout(function ():void { const userList:ArrayList = new ArrayList(room.userList); this.li_users.dataProvider = userList; // This is where the error gets thrown },1000); } My MXML Code: <?xml version="1.0" encoding="utf-8"?> <mx:ViewStack xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" initialize="preGame_initializeHandler(event)" > <fx:Script source="PreGame.as"/> <s:NavigatorContent id="nc_loginScreen"> /** Login Screen Code **/ </s:NavigatorContent> /** Start of Waiting Room code **/ <s:NavigatorContent id="waitingRoom"> <s:Panel id="pn_users" width="400" height="400" title="Users"> /** This is the List in question **/ <s:List id="li_users" width="100%" height="100%"/> </s:Panel> </s:NavigatorContent> </mx:ViewStack> However, I keep getting this error: TypeError: Error #1010: A term is undefined and has no properties Any ideas what I'm doing wrong? The arrayList has data, so I know it's not empty/null.

  • WDK build-process hooks: need incremental build with auto-versioning

    - by Mystagogue
    I've previously gotten incremental builds with auto-versioning working in a team build setting for user-mode code, but now I'm dealing with the builds of WDK device drivers. It's a whole new ball-game. I need to know what extension point, or hook, is available in the WDK build that occurs after the driver has been selected to be incrementally built, but before it actually starts building the object files. More specifically, I have a .rc file that contains the version of the device driver. I need to update the version in that file ONLY IF the driver is going to be built anyway. If I bump the value in the .rc file prematurely, it will cause the incremental build to kick-off (that is bad). If I wait too long, then the incremental build won't see that I've changed the .rc file. Either way, I do need the WDK to realize that the new version I've placed into the .rc file needs to be built into a new .res file and linked. How do I do this? What suggested extension points should I play with? Is there a link-tutorial on the WDK build process that is particularly revealing regarding this topic?

  • What exactly is the difference between the Dreamhost IDE and Netbeans?

    - by mikemick
    I just started using Netbeans about a week ago, and really like it thus far. Now I'm seeing something about Dreamhost IDE which I guess is a program that is built using the Netbeans platform. I use Dreamhost as the hosting company for many of my projects. What is the benefit of using Dreamhost IDE over Netbeans? Documentation on the software is non-existent from what I can tell (not even a mention in the Dreamhost wiki). All I was able to find was a short description of what it was on a Sourceforge download page, and I found a short silent video on YouTube demoing it. So I guess I'm asking, what features is it bringing to the table, and what is the difference between it and Netbeans? The description on the Sourceforge page is as follows (typos retained)... DreamHost IDE is php and ruby integrated development environment built on NetBeans IDE and provides easy deploy of your applications to the DreamHost services. Also provides you an easy eay hew to setup these services. Maybe the answer is in the description, and I just don't comprehend it?
