  • How do I run my application while a UAC dialog window is showing?

    - by Ray
    I have an application that I wrote in .NET. It needs to remain running and have access the desktop that the UAC dialog windows open on and interact with that desktop using keyboard and mouse events. It's sort of like a VNC program. Imagine you are running a VNC program and a UAC window pops up, you want your VNC program to still be able to control the desktop with the UAC window in it so that the user can move the mouse and click the OK button on the UAC dialog. Can anyone tell me how I would go about doing that? Thanks

  • Poll for pressed buttons in Java

    - by directedition
    I have a WorldWind application build based on the Java SDK. It has a great event handler for detecting when you click on objects, but I've run into a snag. While I can click on and select individual objects, I can't determine if the user is pressing the control key while they click (if they want to select multiple objects). I can implement event handlers for both the mouse and the keyboard, but I can't for the life of me figure out how to tie the two together. How could I make my mouse listener poll the system for a list of currently depressed keys?

  • jQuery link nudge and color transform

    - by DaveKingsnorth
    Hey everyone, I have achieved the effect described in the title using the following code: $(document).ready(function(){ $('.button').mousedown(function() { $(this).animate({ 'top': '3px' }, 70); }); $('.button').mouseup(function() { $(this).animate({ 'top': '0px' }, 70); }); $('.button').hover(function() { $(this).stop().animate({ color: '#fff', backgroundColor: '#000' }, 250); }); $('.button').mouseout(function() { $(this).stop().animate({ color: '#000', backgroundColor: '#fff' }, 250); }); }); I am pretty sure that that this code can be reduced significantly, can anyone help me out? Please note that I want the button to animate when the mouse is clicked and not return to it's original position until the mouse is released. Cheers

  • Having two backgrounds for an active menu item?

    - by HollerTrain
    Hi I have a dynamic menu where the ul li items change in width depending on the text set in the CMS (Joomla). They want the menu item, on mouse over, to both have 1. a repeated background image and 2. an image placed at the top (http://screencast.com/t/Zjk4YTJmNGQ). Now, I'm great with doing the repeated background image on a mouse over and that would be great, but I am not sure how to get both of these images in one css declaration. Any help would be greatly appreciated, as I haven't learned this technique yet :(

  • How to place some text over the DIV without breaking hover area of this DIV?

    - by Andr
    I'm total noob with CSS and it looks like hell =/ I have absolute positioned DIV and I handle mouse events over this DIV with JS like this: <div style='position: absolute; left: 0px; width:50px; height: 50px;' onmouseover='this.style.border="2px solid red"' onmouseout='this.style.border="1px solid black"'> </div> <div style='position: absolute;'>SOME TEXT</div> I need to place some text over this DIV and over the few same DIVs, but if I place any element over this DIV onMouseOut event is firing when mouse cursor switch to text. Tag with text can't be inside the DIV. Playing with z-index didn`t help. My browser is IE8.

  • "Volkswagen Passat" Navigation

    - by joe_midi
    http://web.vw.com/all-new-passat-experience/ The navigation on this .swf is very impressive, and I was wondering how I would go about replicating it. The way each of the sections Design / Technology / Safety / Performance I want to know how each section can expand and still fit together. I've started with MOUSE_OVER events, but I'm not entirely sure how to order them so each section is the right size for every mouse over Event. This is the code I have for each "Section", I have created a movie clip with a Mask that expands on mouse over and brings the selected clip to the highest depth. this.firstButton01.addEventListener(MouseEvent.MOUSE_OVER, firstButton01OVER) function firstButton01OVER(e:Event):void { this.firstButton01.gotoAndPlay(2); this.setChildIndex(firstButton01,this.numChildren-1); }

  • Having an issue wit mouseup event

    - by user3680715
    Hello everyone I have this code working fine but I want the script to stop on the mouse up event. Here is an example of what I have now. How can I stop the script on mouse up event so that it looks like it only shows the coordinates when dragging over the image. Thank you! http://jsfiddle.net/Hc7x4/20/ $(document).ready(function () { $("#map-catcher").mousedown(function (e) { $("#map-catcher").mousemove(function (e) { $("#coord").text("x:"+e.offsetX+", y:"+e.offsetY); return; }); $("#map-catcher").mouseup(function (e) { return; }); }); });

  • C# Deserializing to a dictionary<string, Object>

    - by lovecraft
    I'm writing a C#/VB application to connect to a database and do stuff with the data. I was given this code to take a serialized byte array and deserialized it, which is then written to a Dictionary The line of code is: Dictionary<string, Object> DictionaryEmployee = (Dictionary<string, Object> Deserializer(byteArrayEmp)); The errors I'm getting are exceedingly unhelpful. "Only assignment, call, increment, decrement, await, and new object expressions can be used as a statement" if I mouse over Object and "Using the generic type 'System.Collections.Generic.Dictionary' requires 2 type arguments if I mouse over Dictionary.

  • How can I scale movement physics functions to frames per second (in a game engine)?

    - by Richard
    I am working on a game in Javascript (HTML5 Canvas). I implemented a simple algorithm that allows an object to follow another object with basic physics mixed in (a force vector to drive the object in the right direction, and the velocity stacks momentum, but is slowed by a constant drag force). At the moment, I set it up as a rectangle following the mouse (x, y) coordinates. Here's the code: // rectangle x, y position var x = 400; // starting x position var y = 250; // starting y position var FPS = 60; // frames per second of the screen // physics variables: var velX = 0; // initial velocity at 0 (not moving) var velY = 0; // not moving var drag = 0.92; // drag force reduces velocity by 8% per frame var force = 0.35; // overall force applied to move the rectangle var angle = 0; // angle in which to move // called every frame (at 60 frames per second): function update(){ // calculate distance between mouse and rectangle var dx = mouseX - x; var dy = mouseY - y; // calculate angle between mouse and rectangle var angle = Math.atan(dy/dx); if(dx < 0) angle += Math.PI; else if(dy < 0) angle += 2*Math.PI; // calculate the force (on or off, depending on user input) var curForce; if(keys[32]) // SPACE bar curForce = force; // if pressed, use 0.35 as force else curForce = 0; // otherwise, force is 0 // increment velocty by the force, and scaled by drag for x and y velX += curForce * Math.cos(angle); velX *= drag; velY += curForce * Math.sin(angle); velY *= drag; // update x and y by their velocities x += velX; y += velY; And that works fine at 60 frames per second. Now, the tricky part: my question is, if I change this to a different framerate (say, 30 FPS), how can I modify the force and drag values to keep the movement constant? That is, right now my rectangle (whose position is dictated by the x and y variables) moves at a maximum speed of about 4 pixels per second, and accelerates to its max speed in about 1 second. BUT, if I change the framerate, it moves slower (e.g. 30 FPS accelerates to only 2 pixels per frame). So, how can I create an equation that takes FPS (frames per second) as input, and spits out correct "drag" and "force" values that will behave the same way in real time? I know it's a heavy question, but perhaps somebody with game design experience, or knowledge of programming physics can help. Thank you for your efforts. jsFiddle: http://jsfiddle.net/BadDB

  • Modify MDT wizard to automate computer naming

    - by Jeramy
    I originally posted this question to StackOverflow, but upon further consideration it might be more appropriate here. Situation: I am imaging new systems using MDT Lite-Touch. I am trying to customize the wizard to automate the naming of new systems so that they include a prefix "AG-", a department code which is selected from a drop-down box in the wizard page (eg. "COMM"), and finally the serial number of the computer being imaged, so that my result in this case would be "AG-COMM-1234567890" Status: I have banged away at this for a while but my Google searches have not turned up answers, my trial-and-error is not producing useful error messages and I think I am missing some fundamentals of how to get variables from the wizard page into the variables used by the lite-touch wizard. Progress: I first created the HTML page which I will include below and added a script to the page to concatenate the pieces into a variable called OSDComputername which, for testing, I could output in a msgbox and get to display correctly. The problem with this is I don't know how to trigger the script then assign it to the OSDComputername variable that is used throughout the rest of the Light-Touch process. I changed the script to a function and added it to DeployWiz_Initization.vbs then used the Initialization field in WDS to call it. I'll include the function below. The problem with this is I would get "Undefined Variable" for OSDComputername and I am not sure it is pulling the data from the HTML correctly. I tried adding the scripting into the customsettings.ini file after the "OSDComputername=" This resulted in the wizard just outputting my code in text as the computer name. I am now trying adding variables to "Properties=" (eg.DepartmentName) in the customsettings.ini, pulling thier value from the HTML Form and setting that value to the variable in my function in DeployWiz_Initization.vbs and calling them after "OSDComputername=" in the fashion "OSDComputername="AG-" & %DepartmentName%" in customsettings.ini I am rebuilding right now and will see how this goes Any help would be appreciated. The HTML page: <HTML> <H1>Configure the computer name.</H1> <span style="width: 95%;"> <p>Please answer the following questions.

  • Why are my USB 2.0 devices hanging Windows XP?

    - by BenAlabaster
    Background on the machine I'm having a problem with: The machine was inherited and appears to be circa 2003 (there's a date stamp on the power supply which leads me to this conclusion). I've got it set up as a Skype terminal for my 2 year old to keep in touch with her grandparents and other members of the family - which everyone loves. It has a DFI CM33-TL/G ATX (identified using SiSoft Sandra) motherboard hosting an Intel Celeron 1.3GHz CPU, 768Mb PC133 SDRAM, a D-LINK WDA-2320 54G Wi-Fi network card and a generic USB 2.0 expansion board based on the NEC uPD720102 chipset containing 3 external and 1 internal USB sockets. It's also hosting a 1.44Mb floppy drive on FDD0, a new 80Gb Western Digital hard drive running as master on IDE0 and a Panasonic DVD+/-RW running as master on IDE1. All this is sitting in a slimline case running off a Macron Power MPT-135 135W Flex power supply. The motherboard is running a version of Award BIOS 05/24/2002-601T-686B-6A6LID4AC-00. Could this be updated? If so, from where? I've raked through the manufacturer's website but can't find any hint of downloads for either drivers or BIOS updates. The hard disk is freshly formatted and built with Windows XP Professional/Service Pack 3 and is up to date with all current patches. In addition to Windows XP, the only other software it's running is Skype 4.1 (4.2 hangs the whole machine as soon as it starts up, requiring a hard boot to recover). It's got a Daytek MV150 15" touch screen hooked up to the on board VGA and COM1 sockets with the most current drivers from the Daytek website and the most current version of ELO-Touchsystems drivers for the touch component. The webcam is a Logitech Webcam C200 with the latest drivers from the Logitech website. The problem: If I hook any devices to the USB 2.0 sockets, it hangs the whole machine and I have to hard boot it to get it back up. If I have any devices attached to the USB 2.0 sockets when I boot up, it hangs before Windows gets to the login prompt and I have to hard boot it to recover. Workarounds found: I can plug the same devices into the on board USB 1.0 sockets and everything works fine, albeit at reduced performance. I've tried 3 different kinds of USB thumb drives, 3 different makes/models of webcams and my iPhone all with the same effect. They're recognized and don't hang the machine when I hook them to the USB 1.0 but if I hook them to the USB 2.0 ports, the machine hangs within a couple of seconds of recognizing the devices were connected. Attempted solutions: I've seen suggestions that this could be a power problem - that the PSU just doesn't have the wattage to drive these ports. While I'm doubtful this is the problem [after all the motherboard has the same standard connector regardless of the PSU wattage], I tried disabling all the on board devices that I'm not using - on board LAN, the second COM port, the AGP connector etc. through the BIOS in what I'm sure is a futile attempt to reduce the power consumption... I also modified the ACPI and power management settings. It didn't have any noticeable affect, although it didn't do any harm either. Could the wattage of the PSU really cause this problem? If it can, is there anything I need to be aware of when replacing it or do I just need to make sure it's got a higher wattage than the current one? My interpretation was that the wattage only affected the number of drives you could hook up to the power connectors, is that right? I've installed the USB card in another machine and it works without issue, so it's not a problem with the USB card itself, and Windows says the card is installed and working correctly... right up until I connect a device to it. The only thing I haven't done which I only just thought of while writing this essay is trying the USB 2.0 card in a different PCI slot, or re-ordering the wi-fi and USB cards in the slots... although I'm not sure if this will make any difference - does anyone have any experience that would suggest this might work? Other thoughts/questions: Perhaps this is an incompatibility between the USB 2.0 card and the BIOS, would re-flashing the BIOS with a newer version help? Do I need to be able to identify the manufacturer of the motherboard in order to be able to find a BIOS edition specific for this motherboard or will any version of Award BIOS function in its place? Question: Does anyone have any ideas that could help me get my USB 2.0 devices hooked up to this machine?

I've got it set up as a Skype terminal for my 2 year old to keep in touch with her grandparents and other members of the family - which everyone loves.

Do I need to be able to identify the manufacturer of the motherboard in order to be able to find a BIOS edition specific for this motherboard or will any version of Award BIOS function in its place? Question: Does anyone have any ideas that could help me get my USB 2.0 devices hooked up to this machine?

  • Why are my USB 2.0 devices hanging Windows XP?

    - by BenAlabaster
    Background on the machine I'm having a problem with: The machine was inherited and appears to be circa 2003 (there's a date stamp on the power supply which leads me to this conclusion). I've got it set up as a Skype terminal for my 2 year old to keep in touch with her grandparents and other members of the family - which everyone loves. It has a generic ATX motherboard with no identifying markings other than one stamp that says "Rev.B". CPU-Z identifies the motherboard model as VT8601 but doesn't provide me with any manufacturer name. On board it has 1 x 10/100 LAN, 2 x USB 1.0, VGA, PS/2 for KB and mouse, parallel port, 2 x serial ports, 2 x IDE, 1 x floppy, 2 x SDRAM slots, 1 x CPU housing that is seating a 1.3GHz Intel Celeron CPU, 3 x PCI, 1 x AGP - although you can only use 2 of the PCI slots if you use the AGP slot due to the physical layout of the board. It's got 768Mb PC133 SDRAM - 1 x 512Mb & 1 x 256Mb installed as well as a D-LINK WDA-2320 54G Wi-Fi network card and a generic USB 2.0 expansion board containing 3 x external + 1 x internal USB connectors - it has a NEC uPD720102 chipset. It has a DVD+/-RW running as master on IDE1 and a 1.44Mb 3.5" floppy drive connected to the floppy connector. It has an 80Gb Western Digital hard drive running as master on IDE0. All this is sitting in a slimline case. I don't know the wattage of the PSU, but can post this later if this proves to be helpful. The motherboard is running a version of Award BIOS for which I don't have the version number to hand but can again post this later if it would be helpful. The hard disk is freshly formatted and built with Windows XP Professional/Service Pack 3 and is up to date with all current patches. In addition to Windows XP, the only other software it's running is Skype 4.1 (4.2 hangs the whole machine as soon as it starts up, requiring a hard boot to recover). It's got a Daytek MV150 15" touch screen hooked up to the on board VGA and COM1 sockets with the most current drivers from the Daytek website and the most current version of ELO-Touchsystems drivers for the touch component. The webcam is a Logitech Webcam C200 with the latest drivers from the Logitech website. The problem: If I hook any devices to the USB 2.0 sockets, it hangs the whole machine and I have to hard boot it to get it back up. If I have any devices attached to the USB 2.0 sockets when I boot up, it hangs before Windows gets to the login prompt and I have to hard boot it to recover. Workarounds found: I can plug the same devices into the on board USB 1.0 sockets and everything works fine, albeit at reduced performance. I've tried 3 different kinds of USB thumb drives, 3 different makes/models of webcams and my iPhone all with the same effect. They're recognized and don't hang the machine when I hook them to the USB 1.0 but if I hook them to the USB 2.0 ports, the machine hangs within a couple of seconds of recognizing the devices were connected. Attempted solutions: I've seen suggestions that this could be a power problem - that the PSU just doesn't have the wattage to drive these ports. While I'm doubtful this is the problem [after all the motherboard has the same standard connector regardless of the PSU wattage], I tried disabling all the on board devices that I'm not using - on board LAN, the second COM port, the AGP connector etc. through the BIOS in what I'm sure is a futile attempt to reduce the power consumption... I also modified the ACPI and power management settings. It didn't have any noticeable affect, although it didn't do any harm either. Could the wattage of the PSU really cause this problem? If it can, is there anything I need to be aware of when replacing it or do I just need to make sure it's got a higher wattage than the current one? My interpretation was that the wattage only affected the number of drives you could hook up to the power connectors, is that right? I've installed the USB card in another machine and it works without issue, so it's not a problem with the USB card itself, and Windows says the card is installed and working correctly... right up until I connect a device to it. The only thing I haven't done which I only just thought of while writing this essay is trying the USB 2.0 card in a different PCI slot, or re-ordering the wi-fi and USB cards in the slots... although I'm not sure if this will make any difference - does anyone have any experience that would suggest this might work? Other thoughts/questions: Perhaps this is an incompatibility between the USB 2.0 card and the BIOS, would re-flashing the BIOS with a newer version help? Do I need to be able to identify the manufacturer of the motherboard in order to be able to find a BIOS edition specific for this motherboard or will any version of Award BIOS function in its place? Question: Does anyone have any ideas that could help me get my USB 2.0 devices hooked up to this machine?

  • How did I get here? My route to Android, iPhone, Windows Phone 7, and interest in Mobile Devices

    - by Wallym
    I get asked all the time how/why I got interested in mobile and jumped on this fairly early.  I tend to give half answers because it wasn't just one thing that took me to mobile, but a whole host of separate ivents culminating in a specific event where I wasdoing market research in May/June 2008.  Let me throw out the events and the facts about me: I tend to like new, different, cool stuff.  I jumped on .NET early on.  I jumped on Ajax early on.  I don't jump on every new technology that comes down the road, I'm probably the only person on the planet that doesn't "get" MVC, though I acknowledge that a lot of people do and it solves a number of problems in the default settings of ASP.NET WebForms. I remember buying an early Windows CE device. It was interesting, but dang, this stylus thing sucks. After I lost my third stylus, i just gave up.  I got my first mobile phone in early 1999.  Reception was crappy, but I could see the value in being mobile. In 1999, I worked on a manufacturing systems project.  One piece of the projects was a set of handheld devices on the shop floor.  While the UI was a crappy DOS based, yes I said DOS as in Disk Operating System Version 6.22, I could see that the wireless world was a direction I wanted to be in. In 2000, Microsoft released the first public alpha of .NET.  Very cool stuff indeed.  One piece of the puzzle was a set of mobile controls for ASP.NET.  I build numerous test apps as well as mobile version using these mobile controls.  Now, the mobile UIs of the time were based on WML, which was crap. I could real all the analysis of mobile and read all about growth rates.  Now, you have to realize that growth rates can be impressive when dealing with small numbers, but I knew it was a comer. In our first book, I got talked out of mobile because of the line from the publisher "Wally, mobile doesn't sell." Blackberry was the dominant device of the mid 2000s.  Its users were referred to as "Crackberry addicts."  Unfortunately, the mobile development experience for native apps was crap and the web experience was fairly rough as well, but if they could get the ecosystem started, other phones and better blackberryies would come out.  I finally jumped into using a blackberry. Sometime around 2006, I heard "Wally, mobile doesn't sell" again.  Now, anyone that knows me knows that someone saying something like this to me means I'll keep trying it. The phones of the mid 2000s were moving to be more graphical, but there were too many that had this idea that they had to use a stylus.  Stylus suck.  They get lost too easily. I worked on a project in 2007 and 2008 for a startup trying to answer the question of "What is there to do where I am at?"  For some reason, they wanted to be tied to PCs.  As it became obvious that they were having problems, their investor asked us to do some market research and to figure out what the marketplace did want.  One of the important things that I figured out was the we lived in a mobile world and if you had a mobile app, it need to be on a mobile device, not tied to a desktop/laptop/netbook device.  If there was any single event, this was it - I was doing some market research and sat and talked to people in a bar/restaurant in Atlanta called "The Grove" on Lavista.  The consensus of the people that I talked to was that they wanted their data where ever they were at, laptop, pc, mobile, whereever. In 2007, Apple released the iPhone.  Wow, what an impressive device, even with all the problems of a 1st generation device.  I bought an iPod Touch 1st generation to understand touch better, one of the best decisions I ever made. I decided in late 2008, to make a move into cloud, for a number of reasons.  I was working on an example app.  In April, 2009, one of my friends at Microsoft said "don't mention my name with this, but you need an iPhone front end for this app."  How do you get on the iPhone.  Well, there are a number of ways including: ObjectiveC.  Its hard to teach an old dog new tricks, and this dog knows .NET, not ObjectiveC. HTML, web, javascript optimized interface.  yeah, this is possible. PhoneGap.  Now, this is interesting, take an html interface and get it to run on the iPhone, Android, Blackberry, and other platforms.  I thought that this way made the most sense for me until......... MonoTouch.  In May/June 2009, Novell announced a way for .NET/c# developers to write apps for the iPhone.  This is the way that made the most sense to me. Titanium by Appcelerator.  This is similar in concept to PhoneGap.  I haven't played with this much but do want to learn more about it. In July, 2009, I emailed one of my contacts at Wrox to see if they would be interested in a short MonoTouch ebook in their Wrox Blox format.  I fully expected another  response along the lines of "Wally, mobile doesn't sell."  The response I got was "Wally, iPhone is H O T, get started immediately, can you have this to me before Labor Day."  Not quite the response I expected.  Thankfully, we didn't make the Labor Day, first draft date. I kept pushing back because I had a feeling that things were not going to be quite as polished and feature rich as necessary.  After all, Novell doesn't have the resouces of Microsoft's developer division. The ebook shipped on November 30, 2009. On about December, 15, 2009, my editor emailed and said "Your ebook is selling really well, lets do a full book and it by March 1 so get started."  Thankfully, guys like Craig Dunn and Chris Hardy were interested along with Martin and Ror joinged us later on. I bought my wife an iPhone 3Gs in early 2010 to go along with all my iPod Touch devices. I tried to pretend in 2010 that I wasn't that interested in mobile and still had interest in the desktop technologies.  I love the technologies and continue to use them today, but that isn't where my interest is right now.  I'm just about all mobile all the time with my energies.  Our book shipped in the beginning of July, 2010 right in the middle of the Apple FUD.I've been looking at Mobile Web as a way around the AppStores and Apple FUD problems of 2010. With all the Apple self FUD, we became interested in Android.I went up to Dino Esposito at DevConnections in Las Vegas at introduced myself. I've always tried to keep up with what Dino has been doing. I was shocked, he wanted to meet me.  We must have talked for 1.5 hours. It was way more time than I deserved. If you get a chance, go and introduce yourself to Dino. He's a great guy. Microsoft released Windows Phone 7 in the Fall of 2010.  I'm not doing development on that platform at this time.  I think they have a very interesting user interface.  The devices are being positively reviewed.  For my purposes, the devices are limited at this point in time.  We'll see what 2011 brings as far as updates to the operating system.  I need multitasking/background processing and html5 in the browser. Add that as well as acceptance in the marketplace and I'll be more interested in the device. Obviosuly, I'm now working on a MonoDroid book . I own Android and iPhone/iOS devices.  I am currently working on some startup ideas and am exploring as much in that area as I can. For 2011, I'm planning on speaking at Android Developer's Conference (AnDevCon) and Mobile Connections.  I'm really excited about this. I have a couple of magazine articles coming out in 2011 on Android and iPhone development with the Mono technologies.is Mono "The Answer"? What's "The Question?" I think it will work for me.  It might work for you, it might not.  it depends on your situation.  Its the current horse that I am riding. I might find a better horse tomorrow. So, that's how I got here.  I'm in love with mobile.  Mobile native apps on the device as well as mobile web.  I'm into all this cool stuff.  Where are you at?

  • Need help with a possible memory management problem(leak) regarding NSMutableArray

    - by user309030
    Hi, I'm a beginner level programmer trying to make a game app for the iphone and I've encountered a possible issue with the memory management (exc_bad_access) of my program so far. I've searched and read dozens of articles regarding memory management (including apple's docs) but I still can't figure out what exactly is wrong with my codes. So I would really appreciate it if someone can help clear up the mess I made for myself. - (void)viewDidLoad { [super viewDidLoad]; self.gameState = gameStatePaused; fencePoleArray = [[NSMutableArray alloc] init]; fencePoleImageArray = [[NSMutableArray alloc] init]; fenceImageArray = [[NSMutableArray alloc] init]; mainField = CGRectMake(10, 35, 310, 340); .......... [NSTimer scheduledTimerWithTimeInterval:0.05 target:self selector:@selector(gameLoop) userInfo:nil repeats:YES]; } So basically, the player touches the screen to set up the fences/poles -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { if(.......) { ....... } else { UITouch *touch = [[event allTouches] anyObject]; currentTapLoc = [touch locationInView:touch.view]; NSLog(@"%i, %i", (int)currentTapLoc.x, (int)currentTapLoc.y); if(CGRectContainsPoint(mainField, currentTapLoc)) { if([self checkFence]) { onFencePole++; //this 3 set functions adds their respective objects into the 3 NSMutableArrays using addObject: [self setFencePole]; [self setFenceImage]; [self setFencePoleImage]; ....... } } else { ....... } } } } The setFence function (setFenceImage and setFencePoleImage is similar to this) -(void)setFencePole { Fence *fencePole; if (!elecFence) { fencePole = [[Fence alloc] initFence:onFencePole fenceType:1 fencePos:currentTapLoc]; } else { fencePole = [[Fence alloc] initFence:onFencePole fenceType:2 fencePos:currentTapLoc]; } [fencePoleArray addObject:fencePole]; [fencePole release]; and whenever I press a button in the game, endOpenState is called to clear away all the extra images(fence/poles) on the screen and also to remove all existing objects in the 3 NSMutableArray -(void)endOpenState { ........ int xMax = [fencePoleArray count]; int yMax = [fenceImageArray count]; for (int x = 0; x < xMax; x++) { [[fencePoleImageArray objectAtIndex:x] removeFromSuperview]; } for (int y = 0; y < yMax; y++) { [[fenceImageArray objectAtIndex:y] removeFromSuperview]; } [fencePoleArray removeAllObjects]; [fencePoleImageArray removeAllObjects]; [fenceImageArray removeAllObjects]; ........ } The crash happens here at the checkFence function. -(BOOL)checkFence { if (onFencePole == 0) { return YES; } else if (onFencePole >= 1 && onFencePole < currentMaxFencePole - 1) { CGPoint tempPoint1 = currentTapLoc; CGPoint tempPoint2 = [[fencePoleArray objectAtIndex:onFencePole-1] returnPos]; // the crash happens at this line if ([self checkDistance:tempPoint1 point2:tempPoint2]) { return YES; } else { return NO; } } else if (onFencePole == currentMaxFencePole - 1) { ...... } else { return NO; } } What I'm thinking of is that fencePoleArray got messed up when I used [fencePoleArray removeAllObjects] because it doesn't crash when I comment it out. It would really be great if someone can explain to me what went wrong. And thanks in advance.

  • Need help with a memory management problem in my game model

    - by user309030
    Hi, I'm a beginner level programmer trying to make a game app for the iphone and I've encountered a possible issue with the memory management (exc_bad_access) of my program so far. I've searched and read dozens of articles regarding memory management (including apple's docs) but I still can't figure out what exactly is wrong with my codes. So I would really appreciate it if someone can help clear up the mess I made for myself. //in the .h file @property(nonatomic,retain) NSMutableArray *fencePoleArray; @property(nonatomic,retain) NSMutableArray *fencePoleImageArray; @property(nonatomic,retain) NSMutableArray *fenceImageArray; //in the .m file - (void)viewDidLoad { [super viewDidLoad]; self.gameState = gameStatePaused; fencePoleArray = [[NSMutableArray alloc] init]; fencePoleImageArray = [[NSMutableArray alloc] init]; fenceImageArray = [[NSMutableArray alloc] init]; mainField = CGRectMake(10, 35, 310, 340); .......... [NSTimer scheduledTimerWithTimeInterval:0.05 target:self selector:@selector(gameLoop) userInfo:nil repeats:YES]; } So basically, the player touches the screen to set up the fences/poles -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { if(.......) { ....... } else { UITouch *touch = [[event allTouches] anyObject]; currentTapLoc = [touch locationInView:touch.view]; NSLog(@"%i, %i", (int)currentTapLoc.x, (int)currentTapLoc.y); if(CGRectContainsPoint(mainField, currentTapLoc)) { if([self checkFence]) { onFencePole++; //this 3 set functions adds their respective objects into the 3 NSMutableArrays using addObject: [self setFencePole]; [self setFenceImage]; [self setFencePoleImage]; ....... } } else { ....... } } } } The setFence function (setFenceImage and setFencePoleImage is similar to this) -(void)setFencePole { Fence *fencePole; if (!elecFence) { fencePole = [[Fence alloc] initFence:onFencePole fenceType:1 fencePos:currentTapLoc]; } else { fencePole = [[Fence alloc] initFence:onFencePole fenceType:2 fencePos:currentTapLoc]; } [fencePoleArray addObject:fencePole]; [fencePole release]; and whenever I press a button in the game, endOpenState is called to clear away all the extra images(fence/poles) on the screen and also to remove all existing objects in the 3 NSMutableArray. Point is to remove all the objects in the NSMutableArrays but keep the array itself so it can be reused later. -(void)endOpenState { ........ int xMax = [fencePoleArray count]; int yMax = [fenceImageArray count]; for (int x = 0; x < xMax; x++) { [[fencePoleImageArray objectAtIndex:x] removeFromSuperview]; } for (int y = 0; y < yMax; y++) { [[fenceImageArray objectAtIndex:y] removeFromSuperview]; } [fencePoleArray removeAllObjects]; [fencePoleImageArray removeAllObjects]; [fenceImageArray removeAllObjects]; ........ } The crash happens here at the checkFence function. -(BOOL)checkFence { if (onFencePole == 0) { return YES; } else if (onFencePole >= 1 && onFencePole < currentMaxFencePole - 1) { CGPoint tempPoint1 = currentTapLoc; CGPoint tempPoint2 = [[fencePoleArray objectAtIndex:onFencePole-1] returnPos]; // the crash happens at this line if ([self checkDistance:tempPoint1 point2:tempPoint2]) { return YES; } else { return NO; } } else if (onFencePole == currentMaxFencePole - 1) { ...... } else { return NO; } } So the problem here is, everything works fine until checkFence is called the 2nd time after endOpenState is called. So its like tap_screen - tap_screen - press_button_to_call_endOpenState - tap screen - tap_screen - crash What I'm thinking of is that fencePoleArray got messed up when I used [fencePoleArray removeAllObjects] because it doesn't crash when I comment it out. It would really be great if someone can explain to me what went wrong. And thanks in advance.

  • Visual Studio 2010 Zooming – Keyboard Commands, Global Zoom

    - by Jon Galloway
    One of my favorite features in Visual Studio 2010 is zoom. It first caught my attention as a useful tool for screencasts and presentations, but after getting used to it I’m finding that it’s really useful when I’m developing – letting me zoom out to see the big picture, then zoom in to concentrate on a few lines of code. Zooming without the scroll wheel The common way you’ll see this feature demonstrated is with the mouse wheel – you hold down the control key and scroll up or down to change font size. However, I’m often using this on my laptop, which doesn’t have a mouse wheel. It turns out that there are other ways to control zooming in Visual Studio 2010. Keyboard commands You can use Control+Shift+Comma to zoom out and Control+Shift+Period to zoom in. I find it’s easier to remember these by the greater-than / less-than signs, so it’s really Control+> to zoom in and Control+< to zoom out. Like most Visual Studio commands, you can change those the keyboard buttons. In the tools menu, select Options / Keyboard, then either scroll down the list to the three View.Zoom commands or filter by typing View.Zoom into the “Show commands containing” textbox. The Scroll Dropdown If you forget the keyboard commands and you don’t have a scroll wheel, there’s a zoom menu in the text editor. I’m mostly pointing it out because I’ve been using Visual Studio 2010 for months and never noticed it until this week. It’s down in the lower left corner. Keeping Zoom In Sync Across All Tabs Zoom setting is per-tab, which is a problem if you’re cranking up your font sizes for a presentation. Fortunately there’s a great new Visual Studio Extension called Presentation Zoom. It’s a nice, simple extension that just does one thing – updates all your editor windows to keep the zoom setting in sync. It’s written by Chris Granger, a Visual Studio Program Manager, in case you’re worried about installing random extensions. See it in action Of course, if you’ve got Visual Studio 2010 installed, you’ve hopefully already been zooming like mad as you read this. If not, you can watch a 2 minute video by the Visual Studio showing it off.
