  • CSS Differences Between IE and FF

    - by Joe Majewski
    I hope I'm not breaking any rules by asking a question that pertains to a project I'm working on. If you view my page here and view it in Firefox and again in Internet Explorer, the width of the main content boxes differs. In Firefox, everything aligns perfectly with the advertisement at the top of the page, but in IE, the width of the content boxes seems to fall short by about 20 or so pixels. My question is obvious by now, but what is causing the width in IE to fall short, and what would a simple solution be? If I happen to be breaking the rules by asking a question that is not generic enough to benefit others, then allow me to rephrase it; what would be the best approach to solving visual differences between browsers? Should I use a separate CSS file for IE, or is there a way to define lines in my CSS file that only get rendered by a specific browser? It would be best if someone could provide me with the necessary CSS to align things properly, but I would be more than happy to learn about how to make the CSS dynamic (if that's possible). Thanks everyone. :)

  • Selectively turning off Devise's flash notices in Rails 3

    - by Sim
    The Devise authentication framework uses flash notices everywhere. This makes it easy to integrate with apps but it leads to poor user experience sometimes. I am wondering what's an easy way to selectively turn off some of the Devise flash notices in my Rails 3 app. In particular, I'd like to get rid of the blatantly obvious signed_in and signed_out flashes. Some searching suggested subclassing the session controller or use something like this but I haven't been able to find any simple solutions to this problem.

  • Publishing WCF .NET 3.5 to IIS 5.1

    - by Adam
    I've been developing a WCF web service using .NET 3.5 with IIS7 and it works perfectly on my local computer. I tried publishing it to a server running IIS 5.1 and even though I can view the WSDL in my browser, the client application doesn't seem to be connecting to it correctly. I launched a packet sniffing app (Charles Proxy) and the response for the first message comes back to the client empty (0 bytes). Every message after the first one times out. The WCF service is part of a larger application that uses ASP .NET 3.5. That application has been working fine on IIS 5.1 for awhile now so I think it's something specific to WCF. I also tried throwing an exception in the SVC file to see if it made it that far and the exception never got thrown so I have a feeling it's something more low level that's not working. Any thoughts? Is there anything I need to install on the IIS5 server? If so how am I still able to view the WSDL in my browser?

  • Using FOR XML AUTO against a synonym

    - by Rick
    We've just switched to synonyms for linked server stuff, and noticed that our FOR XML output is no longer correct. When returning XML results from a view, we could alias the view and that would be assigned as the element name. With synonyms, however, it seems to ignore the alias? We're still mostly on SQL 2005 - this bug doesn't seem to happen on our 2008 instance. Is this a known problem, and any ideas for work-arounds? For example, this is what we used to be able to do: select top 3 number from Numbers as elementname for xml auto <elementname number="0"/><elementname number="1"/><elementname number="2"/> And this is what happens with a synonym: select top 3 number from Numbers_synonym as elementname for xml auto <dbo.Numbers number="0"/><dbo.Numbers number="1"/><dbo.Numbers number="2"/> As you can see, SQL Server seems to use the name of the actual referenced object instead of the alias. This gets worse for cross server queries, because you get the four-part name instead of the nice alias. (eg: <rick_server.rick_database.dbo.Numbers number="0"/>...)

  • Static Analyzer says I have a leak....why?

    - by Walter
    I think this code should be fine but Static Analyzer doesn't like it. I can't figure out why and was hoping that someone could help me understand. The code works fine, the analyzer result just bugs me. Coin *tempCoin = [[Coin alloc] initalize]; self.myCoin = tempCoin; [tempCoin release]; Coin is a generic NSObject and it has an initalize method. myCoin is a property of the current view and is of type Coin. I assume it is telling me I am leaking tempCoin. In my view's .h I have set myCoin as a property with nonatomic,retain. I've tried to autorelease the code as well as this normal release but Static Analyzer continues to say: 1. Method returns an Objective-C object with a +1 retain count (owning reference) 2. Object allocated on line 97 is no longer referenced after this point and has a retain count of +1 (object leaked) Line 97 is the first line that I show.

  • How can I check if a TTTabItem gets selected?

    - by schoash
    I have several TTTabGrids in my view and now I am stuck with the problem, that I can't figure out, how to detect, when a TTTabItem gets touched. If someone selects an item in one of the TTTabGrids I should upadate some labels. Can someone tell me a way how to detect, when the selection in a TTTabGrid gets changed? My code looks like this: @interface MyTTTabGrid : TTTabGrid @end @implementation MyTTTabGrid - (id)initWithFrame:(CGRect)frame columns:(NSInteger)columns{ if (self = [super initWithFrame:frame]) { self.style = TTSTYLE(tabGrid); _columnCount = columns; } return self; } @end - (void)viewDidLoad { [super viewDidLoad]; _tabBarHours = [[MyTTTabGrid alloc] initWithFrame:CGRectMake(10, _tabBarZone.bottom+10, 300, 0) columns:7]; _tabBarHours.backgroundColor = [UIColor clearColor]; NSMutableArray *tmpHours = [[NSMutableArray alloc] init]; int i=6; while (i<20) { [tmpHours addObject:[[[TTTabItem alloc] initWithTitle:[NSString stringWithFormat:@"%d", i]] autorelease]]; i++; } _tabBarHours.tabItems = tmpHours; [_tabBarHours sizeToFit]; [self.view addSubview:_tabBarHours]; [tmpHours release]; }

    I know this has been asked a million times but I think I need to make it a million and one. I am getting "A generic error has occurred in GDI+" when trying to save a new bitmap. I have completely stripped down to the most basic lines of code and I still get the error with the following method: public class HomeController : Controller { public ActionResult Index() { return this.View(); } public void CreatePicture() { try { // THIS WORKS System.IO.File.Copy("C:\\copyTest.bmp", "C:\\test folder\\copyTest2.bmp"); // THIS WORKS System.IO.File.Delete("C:\\test folder\\deleteTest.bmp"); using (Bitmap newBitmap = new Bitmap(120, 120)) { // THIS FAILS newBitmap.Save("C:\\test folder\\test.bmp", ImageFormat.Bmp); } } catch (Exception ex) { throw ex; } } } The code is called from an html link on a blank page within an MVC 3.0 website using anonymous login. View: @Html.ActionLink("Create Picture", "CreatePicture", "Home", new { }) I have checked the folder permissions of "test folder" and have given full access to the following: ASPNET NETWORK SERVICE IUSR I still get the error... what have I missed / done wrong ?

  • How do I controll clipping with non-opaque graphics-item's in Qt?

    - by JJacobsson
    I have a bunch of QGraphicsSvgItem's in a QGraphicsScene that are drawn connected by QGraphicsLineItem's. This show's a graph of a tree-structure. What I want to do is provide a feature where everything but a selected sub-tree becomes transparent. A kind of "highlight this sub-tree" feature. That part was easy, but the results are ugly because now the lines can be seen through the semi-transparent svg's. I am looking for some way to still clip other QGraphicsItem's in the scene to the svg item's, giving the effect that the svg's are semi-transparent windows to the background. I know this code does not use svg's but I figure you can replace that yourself if you are so inclined. int main(int argc, char *argv[]) { QApplication app(argc, argv); QGraphicsScene scene; for( int i = 0; i < 10; ++i ) { QGraphicsLineItem* line = new QGraphicsLineItem; line->setLine( i * 25.0 + 1.0, 0, i * 25.0 + 23.0, 0 ); scene.addItem( line ); } for( int i = 0; i < 11; ++i ) { QGraphicsEllipseItem* ellipse = new QGraphicsEllipseItem; ellipse->setRect( (i * 25.0) - 9.0, -9.0, 18.0, 18.0f ); ellipse->setBrush( QBrush( Qt::green, Qt::SolidPattern ) ); ellipse->setOpacity( 0.5 ); scene.addItem( ellipse ); } QGraphicsView view( &scene ); view.show(); return app.exec(); } I would like the line's to not be seen behind the circle's. I have tried fiddling with the depth-buffer and the stencil buffer using opengl rendering to no avail. How do I get the QGraphicsSvgItem's (or QGraphicsEllipseItem's in the example code) to still clip the lines even though they are semi-transparent?

  • Refactoring Singleton Overuse

    - by drharris
    Today I had an epiphany, and it was that I was doing everything wrong. Some history: I inherited a C# application, which was really just a collection of static methods, a completely procedural mess of C# code. I refactored this the best I knew at the time, bringing in lots of post-college OOP knowledge. To make a long story short, many of the entities in code have turned out to be Singletons. Today I realized I needed 3 new classes, which would each follow the same Singleton pattern to match the rest of the software. If I keep tumbling down this slippery slope, eventually every class in my application will be Singleton, which will really be no logically different from the original group of static methods. I need help on rethinking this. I know about Dependency Injection, and that would generally be the strategy to use in breaking the Singleton curse. However, I have a few specific questions related to this refactoring, and all about best practices for doing so. How acceptable is the use of static variables to encapsulate configuration information? I have a brain block on using static, and I think it is due to an early OO class in college where the professor said static was bad. But, should I have to reconfigure the class every time I access it? When accessing hardware, is it ok to leave a static pointer to the addresses and variables needed, or should I continually perform Open() and Close() operations? Right now I have a single method acting as the controller. Specifically, I continually poll several external instruments (via hardware drivers) for data. Should this type of controller be the way to go, or should I spawn separate threads for each instrument at the program's startup? If the latter, how do I make this object oriented? Should I create classes called InstrumentAListener and InstrumentBListener? Or is there some standard way to approach this? Is there a better way to do global configuration? Right now I simply have Configuration.Instance.Foo sprinkled liberally throughout the code. Almost every class uses it, so perhaps keeping it as a Singleton makes sense. Any thoughts? A lot of my classes are things like SerialPortWriter or DataFileWriter, which must sit around waiting for this data to stream in. Since they are active the entire time, how should I arrange these in order to listen for the events generated when data comes in? Any other resources, books, or comments about how to get away from Singletons and other pattern overuse would be helpful.

    I'm creating a website using ASP.NET MVC 2 and I'm thinking of using the default AccountController and Views to take care of the Users. The only problem is that, for all the rest, I'm using a Postgres database. Is there a way to link The account controller to a User class defined by me? I'm using Nhibernate to connect to the database, so I'll have a User class with whatever fields necessary. Thanks very much.

  • ASP.MVC 2 Model Data Persistance

    - by toccig
    I'm and MVC1 programmer, new to the MVC2. The data will not persist to the database in an edit scenario. Create works fine. Controller: // // POST: /Attendee/Edit/5 [Authorize(Roles = "Admin")] [AcceptVerbs(HttpVerbs.Post)] public ActionResult Edit(Attendee attendee) { if (ModelState.IsValid) { UpdateModel(attendee, "Attendee"); repository.Save(); return RedirectToAction("Details", attendee); } else { return View(attendee); } } Model: [MetadataType(typeof(Attendee_Validation))] public partial class Attendee { } public class Attendee_Validation { [HiddenInput(DisplayValue = false)] public int attendee_id { get; set; } [HiddenInput(DisplayValue = false)] public int attendee_pin { get; set; } [Required(ErrorMessage = "* required")] [StringLength(50, ErrorMessage = "* Must be under 50 characters")] public string attendee_fname { get; set; } [StringLength(50, ErrorMessage = "* Must be under 50 characters")] public string attendee_mname { get; set; } } I tried to add [Bind(Exclude="attendee_id")] above the Class declaration, but then the value of the attendee_id attribute is set to '0'. View (Strongly-Typed): <% using (Html.BeginForm()) {%> ... <%=Html.Hidden("attendee_id", Model.attendee_id) %> ... <%=Html.SubmitButton("btnSubmit", "Save") %> <% } %> Basically, the repository.Save(); function seems to do nothing. I imagine it has something to do with a primary key constraint violation. But I'm not getting any errors from SQL Server. The application appears to runs fine, but the data is never persisted to the Database.

  • NSTimer won't stop it only resets when invalidated & released

    When I press my stop button to stop the timer it just resets to the original time and begins counting down again. I have looked everywhere and all I have found is "invalidate" and it isn't working. I want the time to stop when I hit stop and the label to display the original time.

  • Optimize a views drawing code

    - by xon1c
    Hi, in a simple drawing application I have a model which has a NSMutableArray curvedPaths holding all the lines the user has drawn. A line itself is also a NSMutableArray, containing the point objects. As I draw curved NSBezier paths, my point array has the following structure: linePoint, controlPoint, controlPoint, linePoint, controlPoint, controlPoint, etc... I thought having one array holding all the points plus control points would be more efficient than dealing with 2 or 3 different arrays. Obviously my view draws the paths it gets from the model, which leads to the actual question: Is there a way to optimize the following code (inside the view's drawRect method) in terms of speed? int lineCount = [[model curvedPaths] count]; // Go through paths for (int i=0; i < lineCount; i++) { // Get the Color NSColor *theColor = [model getColorOfPath:[[model curvedPaths] objectAtIndex:i]]; // Get the points NSArray *thePoints = [model getPointsOfPath:[[model curvedPaths] objectAtIndex:i]]; // Create a new path for performance reasons NSBezierPath *path = [[NSBezierPath alloc] init]; // Set the color [theColor set]; // Move to first point without drawing [path moveToPoint:[[thePoints objectAtIndex:0] myNSPoint]]; int pointCount = [thePoints count] - 3; // Go through points for (int j=0; j < pointCount; j+=3) { [path curveToPoint:[[thePoints objectAtIndex:j+3] myNSPoint] controlPoint1:[[thePoints objectAtIndex:j+1] myNSPoint] controlPoint2:[[thePoints objectAtIndex:j+2] myNSPoint]]; } // Draw the path [path stroke]; // Bye stuff [path release]; [theColor release]; } Thanks, xonic
