  • Why is invalid value being thrown?

    - by Nathan Koop
    I've got a DevExpress TextEdit which is databound to a dataset. The field is an optional percentage, (datatype double). When the record gets loaded and there is no value in the field, everything is fine. However, if you type something into the field (IE 100) and then want to remove it afterwards, I get an Invalid Value, error. Why does this occur, and how can I remove it? I do not have any mask or any sort of explicit validation on this field.

  • Firefox Extension Socket Transport

    - by Nathan
    Hey, I'm making a firefox extension and I'm currently trying to get it to send XML data over a local socket to another application that's listening on that socket. Does anyone know what I'm doing wrong in this? Its probably something simple and I'm just having a monday. Thanks. socketConn: function() { var httpLoc = window.top.getBrowser(). selectedBrowser.contentWindow.location.href; var outputData = '<?xml version="1.0"?>' + '<site_data>' + '<session_id></session_id>' + 'site_url>' + httpLoc + '</site_url>' + '<mime_type></mime_type>' + '<data_file>' + filePath + '</data_file>' + '<capture_mode></capture_mode>' + '</site_data>\n'; var transportService = Cc["@mozilla.org/network/socket-transport-service;1"] .getService(Ci.nsISocketTransportService); var transport = transportService.createTransport(["starttls"], 1,"localhost",currentPort, null); var outstream = transport.openOutputStream(0, 0, 0); outstream.write(outputData, outputData.length); var stream = transport.openInputStream(0, 0, 0); var instream = Cc["@mozilla.org/scriptableinputstream;1"] .createInstance(Ci.nsIScriptableInputStream); instream.init(stream); var dataListener = { data : "", onStartRequest: function(request, context){}, onStopRequest: function(request, context, status){ instream.close(); outstream.close(); }, onDataAvailable: function(request, context, inputStream, offset, count){ this.data += instream.read(count); }, };//end dataListener var pump = Cc["@mozilla.org/network/input-stream-pump;1"] .createInstance(Ci.nsIInputStreamPump); pump.init(stream, -1, -1, 0, 0, false); pump.asyncRead(dataListener, null); }//end socketConn Please ask questions about this if you don't understand what I'm trying to do with this.

  • What is the proper query to get all the children in a tree?

    - by Nathan Adams
    Lets say I have the following MySQL structure: CREATE TABLE `domains` ( `id` INT(10) UNSIGNED NOT NULL AUTO_INCREMENT, `domain` CHAR(50) NOT NULL, `parent` INT(11) DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=MYISAM AUTO_INCREMENT=10 DEFAULT CHARSET=latin1 insert into `domains`(`id`,`domain`,`parent`) values (1,'.com',0); insert into `domains`(`id`,`domain`,`parent`) values (2,'example.com',1); insert into `domains`(`id`,`domain`,`parent`) values (3,'sub1.example.com',2); insert into `domains`(`id`,`domain`,`parent`) values (4,'sub2.example.com',2); insert into `domains`(`id`,`domain`,`parent`) values (5,'s1.sub1.example.com',3); insert into `domains`(`id`,`domain`,`parent`) values (6,'s2.sub1.example.com',3); insert into `domains`(`id`,`domain`,`parent`) values (7,'sx1.s1.sub1.example.com',5); insert into `domains`(`id`,`domain`,`parent`) values (8,'sx2.s2.sub1.example.com',6); insert into `domains`(`id`,`domain`,`parent`) values (9,'x.sub2.example.com',4); In my mind that is enough to emulate a simple tree structure: .com | example / \ sub1 sub2 ect My problem is that give sub1.example.com I want to know all the children of sub1.example.com without using multiple queries in my code. I have tried joining the table to itself and tried to use subqueries, I can't think of anything that will reveal all the children. At work we are using MPTT to keep in hierarchal order a list of domains/subdomains however, I feel that there is an easier way to do it. I did some digging and someone did something similar but they required the use of a function in MySQL. I don't think for something simple like this we would need a whole function. Maybe I am just dumb and not seeing some sort of obvious solution. Also, feel free to alter the structure.

  • How to have two UIPickerViews together in one ViewController?

    - by 0SX
    I'm trying to put 2 UIPickerViews together in one ViewController. Each UIPickerView has different data arrays. I'm using interface builder to link the pickers up. I know I'll have to use separate delegates and dataSources but I can't seem to hook everything up with interface builder correctly. Here's all my code: pickerTesting.h #import <UIKit/UIKit.h> #import "picker2DataSource.h" @interface pickerTestingViewController : UIViewController <UIPickerViewDelegate, UIPickerViewDataSource>{ IBOutlet UIPickerView *picker; IBOutlet UIPickerView *picker2; NSMutableArray *pickerViewArray; } @property (nonatomic, retain) IBOutlet UIPickerView *picker; @property (nonatomic, retain) IBOutlet UIPickerView *picker2; @property (nonatomic, retain) NSMutableArray *pickerViewArray; @end pickerTesting.m #import "pickerTestingViewController.h" @implementation pickerTestingViewController @synthesize picker, picker2, pickerViewArray; - (void)viewDidLoad { [super viewDidLoad]; pickerViewArray = [[NSMutableArray alloc] init]; [pickerViewArray addObject:@" 100 "]; [pickerViewArray addObject:@" 200 "]; [pickerViewArray addObject:@" 400 "]; [pickerViewArray addObject:@" 600 "]; [pickerViewArray addObject:@" 1000 "]; [picker selectRow:1 inComponent:0 animated:NO]; picker2.delegate = self; picker2.dataSource = self; } - (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)picker; { return 1; } - (void)pickerView:(UIPickerView *)picker didSelectRow:(NSInteger)row inComponent:(NSInteger)component { } - (NSInteger)pickerView:(UIPickerView *)picker numberOfRowsInComponent:(NSInteger)component; { return [pickerViewArray count]; } - (NSString *)pickerView:(UIPickerView *)picker titleForRow:(NSInteger)row forComponent:(NSInteger)component; { return [pickerViewArray objectAtIndex:row]; } - (void)didReceiveMemoryWarning { // Releases the view if it doesn't have a superview. [super didReceiveMemoryWarning]; // Release any cached data, images, etc that aren't in use. } - (void)viewDidUnload { // Release any retained subviews of the main view. // e.g. self.myOutlet = nil; } - (void)dealloc { [super dealloc]; } @end And I have a separate class for the other datasource. picker2DataSource.h @interface picker2DataSource : NSObject <UIPickerViewDataSource, UIPickerViewDelegate> { NSMutableArray *customPickerArray; } @property (nonatomic, retain) NSMutableArray *customPickerArray; @end picker2DataSource.m #import "picker2DataSource.h" @implementation picker2DataSource @synthesize customPickerArray; - (id)init { // use predetermined frame size self = [super init]; if (self) { customPickerArray = [[NSMutableArray alloc] init]; [customPickerArray addObject:@" a "]; [customPickerArray addObject:@" b "]; [customPickerArray addObject:@" c "]; [customPickerArray addObject:@" d "]; [customPickerArray addObject:@" e "]; } return self; } - (void)dealloc { [customPickerArray release]; [super dealloc]; } - (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)picker2; { return 1; } - (void)pickerView:(UIPickerView *)picker2 didSelectRow:(NSInteger)row inComponent:(NSInteger)component { } - (NSInteger)pickerView:(UIPickerView *)picker2 numberOfRowsInComponent:(NSInteger)component; { return [customPickerArray count]; } - (NSString *)pickerView:(UIPickerView *)picker2 titleForRow:(NSInteger)row forComponent:(NSInteger)component; { return [customPickerArray objectAtIndex:row]; } @end Any help or code examples would be great.

  • VS2010 converted project invalid reference

    - by Nathan
    Opening a .Net 2 project in VS2010 it converts the project without any issues BUT when I attempt to build it fails. The reason is that in VS2005 a reference was added to System.Web.Extensions which is a .Net 3.5 assembly. Now VS2005 never complained at this and quite happily worked but VS2010 is far more strict and won't allow it. I've tried changing the targeted framework to .Net 3.5 but I get another situation there where the web page is never displayed, it simply hangs not even getting to Applicatin_OnStart. Any help either on adding the reference with .Net 2 as target framework (prefered option for time) or getting the .Net 3.5 version to work would be greatly appreciated.

  • Cocoa nextEventMatchingMask not receiving NSMouseMoved event

    - by Jonny
    Hello, I created a local event loop and showed up a borderless window (derived from NSPanel), I found in the event loop there's no NSMouseMoved event received, although I can receive Mouse button down/up events. What should I do to get the NSMouseMoved events? I found making the float window as key window can receive the NSMouseMoved events, but I don't want to change key window. And it appears this is possible, because I found after clicking the test App Icon in System Dock Bar, I can receive the mousemoved events, and the key window/mainwindow are unchanged. Here's the my test code: (Create a Cocoa App project names FloatWindowTest, and put a button to link it with the onClick: IBAction).

  • How does one get rid of fishy behavior in Windows?

    - by Tom Wijsman
    After I had boot my computer this morning there suddenly flooded water from the top of the screen, after which some fishes dropped into it. Now I can barely see what I am doing because the water distorts the view. Sometimes the fish follow the cursor so I need to move it away or wait for the fish to mind their own business. This makes it very annoying to use my system. What have I tried? Reboot the system. This caused the water to deplete from the desktop. Upon reboot, the screen was refilled with water and fishes. Attach another monitor. Same problem, fills that monitor as well and gives me extra fish. Clicking the fish. Makes them turn direction. Right clicking the fish. Changes color of the fish, not really useful. I'm locked out of changing the background or screen saver settings. Hence, I had to post the lady below... Safe mode doesn't save me from the fishes. It does give me another background there, but I can't screenshot easily. Other user accounts experience this as well. The Guest account seems to experience more fish than the other accounts. Using HijackThis, OTL Timekeeper List, Syninternal Autoruns, RootKitRevealer, ShellExView and similar tools I can't seem to find any entries that could be it, the Sysinternals tools show everything as verified. I'm suspecting this to be a driver problem. Randomly removing drivers doesn't seem to alleviate the problem. When removing the Graphics Drivers, it makes my screen black. While that could be considered the solution, it's not what I want. Changing the time / date settings does also not seem to affect the fishes. Changing the time a few years in the future, I would have expected the fishes to be dead. But, the same fishes are still there... They simply won't die! Tried to get used to them. They are really bothering me, looks like they require food. I don't know how to give them food, but apparently they get it elsewhere during reboot... Tried to disable my mouse pointer and use the keyboard. This works, they now swim around more randomly. They do put their attention to huge changes on the screen, so I need to type slow. Or otherwise I can't see what I'm tying exactly. Hold my laptop upside down. This seems to affect the water and fishes, but the water stays in the screen. They seem super resistant against water sickness and confusion though... What does the problem look like? What do I need? A way to get rid of these fishes on my screen forever, they are really annoying me a lot and I'm about to crack the screen to see if that makes them escape. Do you have any idea why this problem is occurring? What are my considerations? Buying an USB fish tank could make the fish leave the screen, I am uncertain though whether the fish could leave the screen through the USB cable. Using the FISh (programming language) which seems to provide EXPRESSIVE POWER and EFFICIENT EXECUTION, I can however not find any examples on how to remove fish. What are my Specifications? I'm using a Sony Vaio Fishy laptop. Sony VAIO VGN-Fishy, VAIO. Processor: 1337 MHz, Intel Core 2 Duo, T5432, 1 MB, Intel PM965 Express, 667 MHz.

  • Cloning a read-write github repository using TortoiseHg

    - by Nathan Palmer
    I'm trying to clone my personal fork on github using the git+ssh protocol with TortoiseHg. It's giving me a rather strange error. Here is the command hg clone git+ssh//[email protected]:myusername/thefork.git This is after I have installed the hg-git module and it works just fine to clone using the git:// syntax. But I believe it's having trouble with the ssh. The error I'm getting is this. importing Hg objects into Git [Error 2] The system cannot find the file specified I have tried adding manually the ssh command into the mercurial.ini file like this [ui] username = [email protected] ssh="C:\Program Files\TortoiseHg\TortoisePlink.exe" -ssh -2 -i "C:\Source\SSHPrivateKey.ppk" But I still get the same error. Any ideas? Thanks.

  • edit commandline with $EDITOR in tcsh

    - by Nathan Fellman
    Today's Daily Vim says this: Assuming you're using the bash shell, the following can be helpful when composing long command lines. Start typing on the command line and then type Ctrl-x Ctrl-e, it should drop you into your system's default editor (hopefully Vim) and allow you to edit the command line from there. Once finished, save the command line, and bash will run the command. Is there any way to do this in tcsh?

  • Hiding a UINavigationController's UIToolbar during viewWillDisappear:

    - by Nathan de Vries
    I've got an iPhone application with a UITableView menu. When a row in the table is selected, the appropriate view controller is pushed onto the application's UINavigationController stack. My issue is that the MenuViewController does not need a toolbar, but the UIViewControllers which are pushed onto the stack do. Each UIViewController that gets pushed calls setToolbarHidden:animated: in viewDidAppear:. To hide the toolbar, I call setToolbarHidden:animated: in viewWillDisappear:. Showing the toolbar works, such that when the pushed view appears the toolbar slides up and the view resizes correctly. However, when the back button is pressed the toolbar slides down but the view does not resize. This means that there's a black strip along the bottom of the view as the other view transitions in. I've tried adding the toolbar's height to the height of the view prior to hiding the toolbar, but this causes the view to be animated during the transition so that there's still a black bar. I realise I can manage my own UIToolbar, but I'd like to use UINavigationControllers built in UIToolbar for convenience. This forum post mentions the same issue, but no workaround is mentioned.

  • VS2010 compiles solution without errors, msbuild fails: "fatal error CS0002: Unable to load message string from resources"

    - by Nathan Ridley
    I'm having a lot of trouble trying to track down the cause of this error message. I have a large Visual Studio 2010 solution which compiles without error on my local machine but on the build server, msbuild fails on one of the projects with the error: fatal error CS0002: Unable to load message string from resources Here's the red error section at the end: Build FAILED. "C:\TeamCity\buildAgent\work\85eff164854b9e67\Libraries\Domainface.Proxy.Common\Domainface.Proxy.Common.csproj" (default target) (9) -> (CoreCompile target) -> CSC : fatal error CS0002: Unable to load message string from resources.

UPDATE I have just run msbuild /version on both machines and it turns out the .net framework versions are very slightly different. Local machine is 4.0.30319.488 and build server is 4.0.30319.1. I'm about to run windows update on the server to allow it to install some updates, as several seem to be .net framework-related, so I'll see if that makes a difference. UPDATE Installing the updates didn't help. Just remembered I copied up csc.exe from the async preview a little while ago in order to facilitate async compilation (the actual async preview had failed to install on the server due to visual studio not being there, but installing visual studio team viewer seems to have fixed that, so i've just run the proper async ctp3 installer to see if that makes a difference.

  • Parsec: backtracking not working

    - by Nathan Sanders
    I am trying to parse F# type syntax. I started writing an [F]Parsec grammar and ran into problems, so I simplified the grammar down to this: type ::= identifier | type -> type identifier ::= [A-Za-z0-9.`]+ After running into problems with FParsec, I switched to Parsec, since I have a full chapter of a book dedicated to explaining it. My code for this grammar is typeP = choice [identP, arrowP] identP = do id <- many1 (digit <|> letter <|> char '.' <|> char '`') -- more complicated code here later return id arrowP = do domain <- typeP string "->" range <- typeP return $ "("++domain++" -> "++range++")" run = parse (do t <- typeP eof return t) "F# type syntax" The problem is that Parsec doesn't backtrack by default, so > run "int" Right "int" -- works! > run "int->int" Left "F# type syntax" unexpected "-" expecting digit, letter, ".", "`" or end of input -- doesn't work! The first thing I tried was to reorder typeP: typeP = choice [arrowP, identP] But this just stack overflows because the grammar is left-recursive--typeP never gets to trying identP because it keeps trying arrowP over and over. Next I tried try in various places, for example: typeP = choice [try identP, arrowP] But nothing I do seems to change the basic behaviours of (1) stack overflow or (2) non-recognition of "-" following an identifier. My mistake is probably obvious to anybody who has successfully written a Parsec grammar. Can somebody point it out?

  • ASP.NET Line Breaks in Title Element

    - by Nathan Taylor
    I'm trying to optimize SEO readability on our websites and one issue I've come across is ASP.NET butchering the title element of my MasterPage. Entered as such in my MasterPage (manually reformatted to remove line breaks caused by the <% %> tags): <title><asp:ContentPlaceHolder ID="TitleContent" runat="server" /> - <%=WebsiteSettings.WebsiteName %></title> This is the output I receive: <title> Home - Website Name</title> As you can see ASP.NET is adding preceding and trailing line breaks where the <asp:ContentPlaceHolder /> is substitute becaused Visual Studio auto-formats <asp:Content /> to start and end with a line break. Obviously, this can be prevented in the Visual Studio formatting options, but this is not ideal because I only would want to remove that behavior for the TitleContent placeholder and not the rest. Is there any way I can ensure my Title is trimmed before it is rendered? I am using MVC so code-behind is not an acceptable option.

No Lastly, we can probe the I2C/SMBus adapters for connected hardware monitoring devices. This is the most risky part, and while it works reasonably well on most systems, it has been reported to cause trouble on some systems. Do you want to probe the I2C/SMBus adapters now?

  • How do I center a UIImageView within a full-screen UIScrollView?

    - by Sebastian Celis
    In my application, I would like to present the user with a full-screen photo viewer much like the one used in the Photos app. This is just for a single photo and as such should be quite simple. I just want the user to be able to view this one photo with the ability to zoom and pan. I have most of it working. And, if I do not center my UIImageView, everything behaves perfectly. However, I really want the UIImageView to be centered on the screen when the image is sufficiently zoomed out. I do not want it stuck to the top-left corner of the scroll view. Once I attempt to center this view, my vertical scrollable area appears to be greater than it should be. As such, once I zoom in a little, I am able to scroll about 100 pixels past the top of the image. What am I doing wrong? @interface MyPhotoViewController : UIViewController <UIScrollViewDelegate> { UIImage* photo; UIImageView *imageView; } - (id)initWithPhoto:(UIImage *)aPhoto; @end @implementation MyPhotoViewController - (id)initWithPhoto:(UIImage *)aPhoto { if (self = [super init]) { photo = [aPhoto retain]; // Some 3.0 SDK code here to ensure this view has a full-screen // layout. } return self; } - (void)dealloc { [photo release]; [imageView release]; [super dealloc]; } - (void)loadView { // Set the main view of this UIViewController to be a UIScrollView. UIScrollView *scrollView = [[UIScrollView alloc] init]; [self setView:scrollView]; [scrollView release]; } - (void)viewDidLoad { [super viewDidLoad]; // Initialize the scroll view. CGSize photoSize = [photo size]; UIScrollView *scrollView = (UIScrollView *)[self view]; [scrollView setDelegate:self]; [scrollView setBackgroundColor:[UIColor blackColor]]; // Create the image view. We push the origin to (0, -44) to ensure // that this view displays behind the navigation bar. imageView = [[UIImageView alloc] initWithFrame:CGRectMake(0.0, -44.0, photoSize.width, photoSize.height)]; [imageView setImage:photo]; [scrollView addSubview:imageView]; // Configure zooming. CGSize screenSize = [[UIScreen mainScreen] bounds].size; CGFloat widthRatio = screenSize.width / photoSize.width; CGFloat heightRatio = screenSize.height / photoSize.height; CGFloat initialZoom = (widthRatio > heightRatio) ? heightRatio : widthRatio; [scrollView setMaximumZoomScale:3.0]; [scrollView setMinimumZoomScale:initialZoom]; [scrollView setZoomScale:initialZoom]; [scrollView setBouncesZoom:YES]; [scrollView setContentSize:CGSizeMake(photoSize.width * initialZoom, photoSize.height * initialZoom)]; // Center the photo. Again we push the center point up by 44 pixels // to account for the translucent navigation bar. CGPoint scrollCenter = [scrollView center]; [imageView setCenter:CGPointMake(scrollCenter.x, scrollCenter.y - 44.0)]; } - (void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; [[[self navigationController] navigationBar] setBarStyle:UIBarStyleBlackTranslucent]; [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleBlackTranslucent animated:YES]; } - (void)viewWillDisappear:(BOOL)animated { [super viewWillDisappear:animated]; [[[self navigationController] navigationBar] setBarStyle:UIBarStyleDefault]; [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleDefault animated:YES]; } - (UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView { return imageView; } @end

  • What is the correct pronunciation of Cocoa?

    - by Nathan S.
    The question says it all: is it coke-ah, co-co, co-co-ah or something else entirely? I've read articles claiming different pronunciations, although there seems to be some consensus towards co-co (e.g. http://www.cocoacrumbs.com/blog/?p=5) Any definitive references that will answer the question for sure?

  • Can't debug code using VS 2010 beta 2

    - by Nathan W
    This is really strange and I can't seem to figure out why it won't work. I have a C# dll that is a add on for another program, the main program is not mine or a .Net app so I am starting it with Start external program in the debugging tab and and passing my program as a command line and the program starts and loads my add on however my Visual Studio debugger doesn't step into the debugger and won't hit my break points. I checked the module window and it's not even loaded in there, I used process explorer and had a look at main program and my dll was loaded into the main app. The project is set to debug, symbols to full and still nothing. I created the project in VS 2008 and it worked fine and am now trying to get this to work in VS 2010 and no go. Anyone know what could be causing this?

  • jQuery lava-lamp-like effect bouncing all over the place!

    - by Nathan Loding
    I followed the tutorial found here and added my own flare to it: tutorial What I was looking to accomplish was to put a specific image on the left and right side of the list item. So instead of just the generic <li id="blob"></li> created in the tutorial, I did <li id="blob"><div class="blob-wrap"><div class="leftimage"></div><div class="rightimage"></div></li> to accomplish the particular effect I wanted. It works beautifully ... except that the image attempts to bounce back the "currentPageItem" if I leave the mouse hovering over one of the list items. Here's a JS Bin example: http://jsbin.com/odome What do I need to do to fix it? jQuery is firing the "hoverOut" function (or whatever you want to call it). But why?
