  • CSS width fills out in IE8 Compatibility mode, works as it should in normal mode

    - by Colin
    I am trying to create a border around an image on the page, and the border works fine in IE8 Normal mode, but fills to 100% of the outer div in IE8 compatibility mode, my css is the following: .page-layout .page-header .page-image { float:left; vertical-align:top; width:170px; } .page-layout .page-header .page-image div, .page-layout .page-header .page-image img { float:left; } .page-image-imgtop { background-image:url('/Style Library/images/pagecontent-image-top-bg.png'); background-repeat:repeat-x; height:6px; float:left; clear:both; width:100%; } .page-image-imgleft { background-image:url('/Style Library/images/pagecontent-image-bg-left.png'); background-repeat:repeat-y; float:left; text-align:right; clear:both; } .page-image-imgright { margin-left:7px; padding-right:8px; background-image:url('/Style Library/images/pagecontent-image-bg-right.png'); background-repeat:repeat-y; background-position:top right; float:left; clear:both; } .page-image-imgbottom { background-image:url('/Style Library/images/pagecontent-image-bottom-bg.png'); background-repeat:repeat-x; height:6px; float:left; clear:both; width:100%; } And the following HTML: <div class="page-image"> <div class="page-image-imgleft"> <div class="page-image-imgtop"> <img src="/Style Library/images/pagecontent-image-top-left.png" style="float:left;" /> <img src="/Style Library/images/pagecontent-image-top-right.png" style="float:right" /> </div> <div class="page-image-imgright"> <img src="MAINIMAGE.jpg" style="border-width:0px;text-align:top;" /> </div> <div class="page-image-imgbottom"> <img src="/Style Library/images/pagecontent-image-bottom-left.png" style="float:left;" /> <img src="/Style Library/images/pagecontent-image-bottom-right.png" style="float:right" /> </div> </div> </div>

  • IErrorHandler doesn't seem to be handling my errors in WCF .. any ideas?

    - by John Nicholas
    Have been readign around on IErrorHandler and want to go the config route. so, I have read the following in an attempt to implement it. MSDN Keyvan Nayyeri blog about the type defintion Rory Primrose Blog I have got it to compile and from the various errors i have fixed it seems like WCF is actually loading the error handler. My problem is that the exception that i am throwing to handle in the error handler doesn;t get the exception passed to it. My service implementation simply calls a method on another class that throws ArgumentOutOfRangeException - however this exception never gets handled by the handler. My web.config <system.serviceModel> <bindings> <basicHttpBinding> <binding name="basic"> <security mode="None" /> </binding> </basicHttpBinding> </bindings> <extensions> <behaviorExtensions> <add name="customHttpBehavior" type="ErrorHandlerTest.ErrorHandlerElement, ErrorHandlerTest, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" /> </behaviorExtensions> </extensions> <behaviors> <serviceBehaviors> <behavior name="exceptionHandlerBehaviour"> <serviceMetadata httpGetEnabled="true"/> <!-- To receive exception details in faults for debugging purposes, set the value below to true. Set to false before deployment to avoid disclosing exception information --> <serviceDebug includeExceptionDetailInFaults="true"/> <customHttpBehavior /> </behavior> </serviceBehaviors> </behaviors> <services> <service behaviorConfiguration="exceptionHandlerBehaviour" name="ErrorHandlerTest.Service1"> <endpoint binding="basicHttpBinding" bindingConfiguration="basic" contract="ErrorHandlerTest.IService1" /> </service> </services> Service Contract [ServiceContract] public interface IService1 { [OperationContract] [FaultContract(typeof(GeneralInternalFault))] string GetData(int value); } The ErrorHandler class public class ErrorHandler : IErrorHandler , IServiceBehavior { public bool HandleError(Exception error) { Console.WriteLine("caught exception {0}:",error.Message ); return true; } public void ProvideFault(Exception error, MessageVersion version, ref Message fault) { if (fault!=null ) { if (error is ArgumentOutOfRangeException ) { var fe = new FaultException<GeneralInternalFault>(new GeneralInternalFault("general internal fault.")); MessageFault mf = fe.CreateMessageFault(); fault = Message.CreateMessage(version, mf, fe.Action); } else { var fe = new FaultException<GeneralInternalFault>(new GeneralInternalFault(" the other general internal fault.")); MessageFault mf = fe.CreateMessageFault(); fault = Message.CreateMessage(version, mf, fe.Action); } } } public void AddBindingParameters(ServiceDescription serviceDescription, ServiceHostBase serviceHostBase, System.Collections.ObjectModel.Collection<ServiceEndpoint> endpoints, BindingParameterCollection bindingParameters) { } public void ApplyDispatchBehavior(ServiceDescription serviceDescription, ServiceHostBase serviceHostBase) { IErrorHandler errorHandler = new ErrorHandler(); foreach (ChannelDispatcherBase channelDispatcherBase in serviceHostBase.ChannelDispatchers) { ChannelDispatcher channelDispatcher = channelDispatcherBase as ChannelDispatcher; if (channelDispatcher != null) { channelDispatcher.ErrorHandlers.Add(errorHandler); } } } public void Validate(ServiceDescription serviceDescription, ServiceHostBase serviceHostBase) { } } And the Behaviour Extension Element public class ErrorHandlerElement : BehaviorExtensionElement { protected override object CreateBehavior() { return new ErrorHandler(); } public override Type BehaviorType { get { return typeof(ErrorHandler); } } }

  • Java Nimbus LAF with transparent text fields

    - by Software Monkey
    I have an application that uses disabled JTextFields in several places which are intended to be transparent - allowing the background to show through instead of the text field's normal background. When running the new Nimbus LAF these fields are opaque (despite setting setOpaque(false)), and my UI is broken. It's as if the LAF is ignoring the opaque property. Setting a background color explicitly is both difficult in several places, and less than optimal due to background images actually doesn't work - it still paints it's LAF default background over the top, leaving a border-like appearance (the splash screen below has the background explicitly set to match the image). Any ideas on how I can get Nimbus to not paint the background for a JTextField? Note: I need a JTextField, rather than a JLabel, because I need the thread-safe setText(), and wrapping capability. Note: My fallback position is to continue using the system LAF, but Nimbus does look substantially better. See example images below. Conclusions The surprise at this behavior is due to a misinterpretation of what setOpaque() is meant to do - from the Nimbus bug report: This is a problem the the orginal design of Swing and how it has been confusing for years. The issue is setOpaque(false) has had a side effect in exiting LAFs which is that of hiding the background which is not really what it is ment for. It is ment to say that the component my have transparent parts and swing should paint the parent component behind it. It's unfortunate that the Nimbus components also appear not to honor setBackground(null) which would otherwise be the recommended way to stop the background painting. Setting a fully transparent background seems unintuitive to me. In my opinion, setOpaque()/isOpaque() is a faulty public API choice which should have been only: public boolean isFullyOpaque(); I say this, because isOpaque()==true is a contract with Swing that the component subclass will take responsibility for painting it's entire background - which means the parent can skip painting that region if it wants (which is an important performance enhancement). Something external cannot directly change this contract (legitimately), whose fulfillment may be coded into the component. So the opacity of the component should not have been settable using setOpaque(). Instead something like setBackground(null) should cause many components to "no long have a background" and therefore become not fully opaque. By way of example, in an ideal world most components should have an isOpaque() that looks like this: public boolean isOpaque() { return (background!=null); }

  • jquery css menu not selecting the active link

    - by Ronedog
    What is wrong with this and how could I fix it. I have css menu (horizontal) that I want the background and font to be changed when one of the items is selected. I found another post that gave me some jquery code to help make it work, and I thought I had it coded right, but when I click on an item to change its class it adds the class, but the background and font stay the same? Any ideas here? Heres the HTML <ul id="menu_nav" class="buttons"> <li> <a href="#" onclick="' . $menu_path . '">Item 1</a> </li> <li> <a href="#" onclick="' . $menu_path . '">Item 2</a> </li> <li> <a href="#" onclick="' . $menu_path . '">Item 3</a> </li> </ul> Heres the CSS: ul#menu_nav { float:left; width:790px; padding:0; margin:0; list-style-type:none; background-color:#000099; } ul#menu_nav a { float:left; text-decoration:none; color:white; background-color:#000099; padding:0.2em 0.6em; border-right:1px solid #CCCCCC; font-family: Tahoma; font-size: 11px; font-style: normal; font-weight: bold; position: relative; height: 21px; line-height:1.85em; } ul#menu_nav a:hover { background-color:#F1F4FE; color:#000099; border-top:1px solid #CCCCCC; } ul#menu_nav li {display:inline;} .selected { background-color:#F1F4FE; color:#000099; border-top:1px solid #CCCCCC; } Here's the Jquery: $(function(){ $(".buttons li>a").click(function(){ $(this).parent().addClass('selected'). // <li> siblings().removeClass('selected'); }); });

  • JS: using 'var me = this' to reference an object instead of using a global array

    - by Marco Demaio
    The example below, is just an example, I know that I don't need an object to show an alert box when user clicks on div blocks, but it's just a simple example to explain a situation that frequently happens when writing JS code. In the example below I use a globally visible array of objects to keep a reference to each new created HelloObject, in this way events called when clicking on a div block can use the reference in the arry to call the HelloObject's public function hello(). 1st have a look at the code: <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html><head><meta http-equiv="Content-Type" content="text/html; charset=windows-1252"> <title>Test </title> <script type="text/javascript"> /***************************************************** Just a cross browser append event function, don't need to understand this one to answer my question *****************************************************/ function AppendEvent(html_element, event_name, event_function) {if(html_element) {if(html_element.attachEvent) html_element.attachEvent("on" + event_name, event_function); else if(html_element.addEventListener) html_element.addEventListener(event_name, event_function, false); }} /****************************************************** Just a test object ******************************************************/ var helloobjs = []; var HelloObject = function HelloObject(div_container) { //Adding this object in helloobjs array var id = helloobjs.length; helloobjs[id] = this; //Appending click event to show the hello window AppendEvent(div_container, 'click', function() { helloobjs[id].hello(); //THIS WORKS! }); /***************************************************/ this.hello = function() { alert('hello'); } } </script> </head><body> <div id="one">click me</div> <div id="two">click me</div> <script type="text/javascript"> var t = new HelloObject(document.getElementById('one')); var t = new HelloObject(document.getElementById('two')); </script> </body></html> In order to achive the same result I could simply replace the code //Appending click event to show the hello window AppendEvent(div_container, 'click', function() { helloobjs[id].hello(); //THIS WORKS! }); with this code: //Appending click event to show the hello window var me = this; AppendEvent(div_container, 'click', function() { me.hello(); //THIS WORKS TOO AND THE GLOBAL helloobjs ARRAY BECOMES SUPEFLOUS! }); thus would make the helloobjs array superflous. My question is: does this 2nd option in your opinion create memoy leaks on IE or strange cicular references that might lead to browsers going slow or to break??? I don't know how to explain, but coming from a background as a C/C++ coder, doing in this 2nd way sounds like a some sort of circular reference that might break memory at some point. I also read on internet about the IE closures memory leak issue http://jibbering.com/faq/faq_notes/closures.html (I don't know if it was fixed in IE7 and if yes, I hope it does not come out again in IE8). Thanks

  • RelativeLayout, ScrollView and navigation bar at bottom

    - by MicNeo
    What I want to do is, make layout like this: Title Date Long text with scrolling Navigation bar stick to the bottom Well I have done everything, however there is a little problem with scrolling. I want only to scroll text. Title and date should be stick to the top, and nav bar to the bottom of activity. And yes, it works, but my nav bar overlaps text :/ I tried everything, there is one solution I found, set fixed height for Scrollview, but this will not work on every devices well, isn't it? I probably could do some calculation in code, and on it change height, but I would like to stay in XML. Any one have any suggestions?

  • Need to add an array into another array at a specified key value

    - by sologhost
    Ok, I have an array like so, but it's not guaranteed to be laid out in this order all of the time... $array = array( 'sadness' => array( 'info' => 'some info', 'info2' => 'more info', 'value' => 'value', ), 'happiness' => array( 'info' => 'some info', 'info2' => 'more info', 'value' => 'the value', ), 'peace' => array( 'info' => 'some info', 'info2' => 'more info', 'value' => 'the value', ) ); Ok, and I'd like to throw in this array right after the happiness key is defined. I can't use the key of "peace" since it must go directly after happiness, and peace might not come after happiness as this array changes. So here's what I need to add after happiness... $another_array['love'] = array( 'info' => 'some info', 'info2' => 'more info', 'value' => 'the value of love' ); So the final output after it gets inputted directly after happiness should look like this: $array = array( 'sadness' => array( 'info' => 'some info', 'info2' => 'more info', 'value' => 'value', ), 'happiness' => array( 'info' => 'some info', 'info2' => 'more info', 'value' => 'the value', ), 'love' => array( 'info' => 'some info', 'info2' => 'more info', 'value' => 'the value of love', ), 'peace' => array( 'info' => 'some info', 'info2' => 'more info', 'value' => 'the value', ) ); Can someone please give me a hand with this. Using array_shift, array_pop, or array_merge doesn't help me at all, since these go at the beginning and at the end of the array. I need to place it directly after a KEY position within $array. Thanks :)

  • Non RBAC User Roles and Permissions System: a role with properties

    - by micha12
    We are currently designing a User Roles and Permissions System in our web application (ASP.NET), and it seems that we have several cases that do no fit within the classical Role-Based Access Control (RBAC). I will post several questions, each devoted to a particular case. This is my second question (the first question is here: http://stackoverflow.com/questions/2839797/non-rbac-user-roles-and-permissions-system-checking-the-users-city). We have the following case: we need to implement a Manager role in our web application. However, a Manager can belong to one or several companies (within a big group of companies for which we are creating this web app). Say, there can be “Manager of companies A and B”, “Manager of company C”, etc. Depending on the companies that the Manager belongs, he has access to certain operations: for example, he can communicate with clients only of those companies that he belongs to. That is, “Manager of companies A and B” can only have contacts with clients of companies A and B, and not with those of company C. He can also view clients’ details pages of companies A and B and not of C, etc. It seems that this case falls within the RBAC. However, this is not really the case. We will need to create a ManagerRole class that will have a Companies property – that is, this will not be just a role as a collection of permissions (like in the classical RBAC), but a role with properties! This was just one example of a role having properties. There will be others: for example, an Administrator role that will also belong to a number of companies and will also have other custom properties. This means that we will a hierarchy or roles classes: class Role – base class class ManagerRole : Role List Companies class AdministratorRole : Role List Companies Other properties We investigated pure RBAC and its implementation in several systems, and found no systems featuring a hierarchy or roles, each having custom properties. In RBAC, roles are just collections of permissions. We could model our cases using permission with properties, like ManagerPermission, AdministratorPermission, but this has a lot of drawbacks, the main being that we will not be able to assign a role like “Manager of Companies A and B” to a user directly, but will have to create a role containing a ManagerPermission for companies A and B… Moreover, a "Manager" seems to be rather a "role" (position in the company) rather than a "permission" from the linguistic point of view. Would be grateful for any ideas on this subject, as well as any experience in this field! Thank you.

  • problem with filtering the dropdownlist in scroll window

    - by Rahul
    Hi all, Problem with filtering Dropdown list. The scenario is : in scroll window there are two fields Document types and type id: Document type is Dropdown list: As per document type selection type id look should display the values. For ex. If I select quote type from document type and if I open type id look up it should display only quotation in the look window. It should work for all the values of document type drop down list values. Its working fine. The item in the document types are: Quote, Order, Invoice, Return, BackOrder. The problem is after saving the data when I am displaying the same record in scroll window, suppose after displaying document type is QUOTE and document id is QTOARD, and in this position I am changing the document type from dropdown QUOTE to ORDER at this time warning message should c ome this range entered is in valid. Because in database table there is no document QTOARD for ORDER type. The same should work for all the condition. The table name is SOP_ID_Setp and key is SOP Type and DocumentID. For that I have written the Stored procedure : create procedure DocTypeFilter @DocumentType as int, @DocumentID as varchar(30) as --declare --@documentype int, --@documentID varchar(30), select * from sop40200 where soptype=@DocumentType and docid=@DocumentID and I have called this SP in Dropdownlist change event. local long retcode; range clear table SOP_ID_SETP; clear field 'SOP Type' of table SOP_ID_SETP; clear field 'Document ID' of table SOP_ID_SETP; range start table SOP_ID_SETP; fill field 'SOP Type' of table SOP_ID_SETP; fill field 'Document ID' of table SOP_ID_SETP; range end table SOP_ID_SETP; if err()=OKAY then call DocTypeFilter,retcode,'Document Type' of window 'Is_Document Type Site_Scroll','Document ID' of window 'Is_Document Type Site_Scroll'; else warning "The range entered is invalid"; clear window 'Is_Document Type Site_Scroll'; fill window 'Is_Document Type Site_Scroll' table is_sop_site_line_temp; end if; Above code not giving the expected output any help pls.

  • Running an allocation simulation repeatedly breaks after the first run.

    - by Az
    Background I have a bunch of students, their desired projects and the supervisors for the respective projects. I'm running a battery of simulations to see which projects the students end up with, which will allow me to get some useful statistics required for feedback. So, this is essentially a Monte-Carlo simulation where I'm randomising the list of students and then iterating through it, allocating projects until I hit the end of the list. Then the process is repeated again. Note that, within a single session, after each successful allocation of a project the following take place: + the project is set to allocated and cannot be given to another student + the supervisor has a fixed quota of students he can supervise. This is decremented by 1 + Once the quota hits 0, all the projects from that supervisor become blocked and this has the same effect as a project being allocated Code def resetData(): for student in students.itervalues(): student.allocated_project = None for supervisor in supervisors.itervalues(): supervisor.quota = 0 for project in projects.itervalues(): project.allocated = False project.blocked = False The role of resetData() is to "reset" certain bits of the data. For example, when a project is successfully allocated, project.allocated for that project is flipped to True. While that's useful for a single run, for the next run I need to be deallocated. Above I'm iterating through thee three dictionaries - one each for students, projects and supervisors - where the information is stored. The next bit is the "Monte-Carlo" simulation for the allocation algorithm. sesh_id = 1 for trial in range(50): for id in randomiseStudents(1): stud_id = id student = students[id] if not student.preferences: # Ignoring the students who've not entered any preferences for rank in ranks: temp_proj = random.choice(list(student.preferences[rank])) if not (temp_proj.allocated or temp_proj.blocked): alloc_proj = student.allocated_proj_ref = temp_proj.proj_id alloc_proj_rank = student.allocated_rank = rank successActions(temp_proj) temp_alloc = Allocated(sesh_id, stud_id, alloc_proj, alloc_proj_rank) print temp_alloc # Explained break sesh_id += 1 resetData() # Refer to def resetData() above All randomiseStudents(1) does is randomise the order of students. Allocated is a class defined as such: class Allocated(object): def __init__(self, sesh_id, stud_id, alloc_proj, alloc_proj_rank): self.sesh_id = sesh_id self.stud_id = stud_id self.alloc_proj = alloc_proj self.alloc_proj_rank = alloc_proj_rank def __repr__(self): return str(self) def __str__(self): return "%s - Student: %s (Project: %s - Rank: %s)" %(self.sesh_id, self.stud_id, self.alloc_proj, self.alloc_proj_rank) Output and problem Now if I run this I get an output such as this (truncated): 1 - Student: 7720 (Project: 1100241 - Rank: 1) 1 - Student: 7832 (Project: 1100339 - Rank: 1) 1 - Student: 7743 (Project: 1100359 - Rank: 1) 1 - Student: 7820 (Project: 1100261 - Rank: 2) 1 - Student: 7829 (Project: 1100270 - Rank: 1) . . . 1 - Student: 7822 (Project: 1100280 - Rank: 1) 1 - Student: 7792 (Project: 1100141 - Rank: 7) 2 - Student: 7739 (Project: 1100267 - Rank: 1) 3 - Student: 7806 (Project: 1100272 - Rank: 1) . . . 45 - Student: 7806 (Project: 1100272 - Rank: 1) 46 - Student: 7714 (Project: 1100317 - Rank: 1) 47 - Student: 7930 (Project: 1100343 - Rank: 1) 48 - Student: 7757 (Project: 1100358 - Rank: 1) 49 - Student: 7759 (Project: 1100269 - Rank: 1) 50 - Student: 7778 (Project: 1100301 - Rank: 1) Basically, it works perfectly for the first run, but on subsequent runs leading upto the nth run, in this case 50, only a single student-project allocation pair is returned. Thus, the main issue I'm having trouble with is figuring out what is causing this anomalous behaviour especially since the first run works smoothly. Thanks in advance, Az

  • Render a view as a string

    - by Dan Atkinson
    Hi all! I'm wanting to output two different views (one as a string that will be sent as an email), and the other the page displayed to a user. Is this possible in ASP.NET MVC beta? I've tried multiple examples: RenderPartial to String in ASP.NET MVC Beta If I use this example, I receive the "Cannot redirect after HTTP headers have been sent.". MVC Framework: Capturing the output of a view If I use this, I seem to be unable to do a redirectToAction, as it tries to render a view that may not exist. If I do return the view, it is completely messed up and doesn't look right at all. Does anyone have any ideas/solutions to these issues i have, or have any suggestions for better ones? Many thanks! Below is an example. What I'm trying to do is create the GetViewForEmail method: public ActionResult OrderResult(string ref) { //Get the order Order order = OrderService.GetOrder(ref); //The email helper would do the meat and veg by getting the view as a string //Pass the control name (OrderResultEmail) and the model (order) string emailView = GetViewForEmail("OrderResultEmail", order); //Email the order out EmailHelper(order, emailView); return View("OrderResult", order); } Accepted answer from Tim Scott (changed and formatted a little by me): public virtual string RenderViewToString( ControllerContext controllerContext, string viewPath, string masterPath, ViewDataDictionary viewData, TempDataDictionary tempData) { Stream filter = null; ViewPage viewPage = new ViewPage(); //Right, create our view viewPage.ViewContext = new ViewContext(controllerContext, new WebFormView(viewPath, masterPath), viewData, tempData); //Get the response context, flush it and get the response filter. var response = viewPage.ViewContext.HttpContext.Response; response.Flush(); var oldFilter = response.Filter; try { //Put a new filter into the response filter = new MemoryStream(); response.Filter = filter; //Now render the view into the memorystream and flush the response viewPage.ViewContext.View.Render(viewPage.ViewContext, viewPage.ViewContext.HttpContext.Response.Output); response.Flush(); //Now read the rendered view. filter.Position = 0; var reader = new StreamReader(filter, response.ContentEncoding); return reader.ReadToEnd(); } finally { //Clean up. if (filter != null) { filter.Dispose(); } //Now replace the response filter response.Filter = oldFilter; } } Example usage Assuming a call from the controller to get the order confirmation email, passing the Site.Master location. string myString = RenderViewToString(this.ControllerContext, "~/Views/Order/OrderResultEmail.aspx", "~/Views/Shared/Site.Master", this.ViewData, this.TempData);

  • Adding simple marker clusterer to google map

    - by take2
    Hi, I'm having problems with adding marker clusterer functionality to my map. What I want is to use custom icon for my markers and every marker has its own info window which I want to be able to edit. I did accomplish that, but now I have problems adding marker clusterer library functionality. I read something about adding markers to array, but I'm not sure what would it exactly mean. Besides, all of the examples with array I have found, don't have info windows and searching through the code I didn't find appropriate way to add them. Here is my code (mostly from Geocodezip.com): <script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script> <script type="text/javascript" src="http://google-maps-utility-library-v3.googlecode.com/svn/trunk/markerclusterer/src/markerclusterer.js"></script> <style type="text/css"> html, body { height: 100%; } </style> <script type="text/javascript"> //<![CDATA[ var map = null; function initialize() { var myOptions = { zoom: 8, center: new google.maps.LatLng(43.907787,-79.359741), mapTypeControl: true, mapTypeControlOptions: {style: google.maps.MapTypeControlStyle.DROPDOWN_MENU}, navigationControl: true, mapTypeId: google.maps.MapTypeId.ROADMAP } map = new google.maps.Map(document.getElementById("map_canvas"), myOptions); var mcOptions = {gridSize: 50, maxZoom: 15}; var mc = new MarkerClusterer(map, [], mcOptions); google.maps.event.addListener(map, 'click', function() { infowindow.close(); }); // Add markers to the map // Set up three markers with info windows var point = new google.maps.LatLng(43.65654,-79.90138); var marker1 = createMarker(point,'Abc'); var point = new google.maps.LatLng(43.91892,-78.89231); var marker2 = createMarker(point,'Abc'); var point = new google.maps.LatLng(43.82589,-79.10040); var marker3 = createMarker(point,'Abc'); var markerArray = new Array(marker1, marker2, marker3); mc.addMarkers(markerArray, true); } var infowindow = new google.maps.InfoWindow( { size: new google.maps.Size(150,50) }); function createMarker(latlng, html) { var image = '/321.png'; var contentString = html; var marker = new google.maps.Marker({ position: latlng, map: map, icon: image, zIndex: Math.round(latlng.lat()*-100000)<<5 }); google.maps.event.addListener(marker, 'click', function() { infowindow.setContent(contentString); infowindow.open(map,marker); }); } //]]> </script>

  • Scriptaculous Draggable/Droppable script not working properly when dragging into a scrolling div

    - by George
    I am using the Scriptaculous Draggable/Droppable scripts and have a problem when dragging into a scrolling div. I have the following layout (based on this question): #grid-container { left:33px; position:relative; width:300px; } #grid { width:310px; height:400px; overflow:auto; margin-bottom: 15px; } #grid-container ul { width:400px; list-style-type:none; white-space: nowrap; } #grid-container li { display:inline; list-style-type:none; padding:5px 15px 5px 15px; height:88px; text-align:center } .image-row { margin-left: 10px; } .grid-image { height:50px; margin-left:-20px; } Here is the html: <div id="grid-container"> <div id="grid"> <div id="row1" class="image-row"> <ul> <li><img id="img1" class="grid-image" src="images/img1.jpg"></li> <li><img id="img2" class="grid-image" src="images/img2.jpg"></li> <li><img id="img3" class="grid-image" src="images/img3.jpg"></li> <li><img id="img4" class="grid-image" src="images/img4.jpg"></li> </ul> </div> <div id="row2" class="image-row"> <ul> <li><img id="img5" class="grid-image" src="images/img5.jpg"></li> <li><img id="img6" class="grid-image" src="images/img6.jpg"></li> </ul> </div> </div> </div> I have another div with draggable items, while all of the img elements are droppable. This works very well for most cases, but when there are too many images for the grid and it has to scroll, I run into issues. I can still drag/drop into most items in that div, but when I scroll down and then try to drag onto an item in the bottom of the list, it drops on the row that was at the bottom before I scrolled the div. Even if I set the scroll attribute when creating the Draggable items, it will scroll the grid div, but not use the proper Droppable item. Is there any way to make the Draggable items drop onto the proper Droppable element regardless of if the containing div is scrolled or not?

  • CSS Background image arbitrarily not getting requested at all

    - by Pekka
    I`m in the process of building a template for Redmine (a project management system based on Ruby on Rails.) Ruby is running on a virtual server from a Bitnami.org installation package. The OS is Windows. The template essentially consists of a styles.css file. In that file, I have the following line: #header { padding: 0px; padding-top: 48px; background-color: #62DFFF; background-image: url(../images/bkg.jpg); background-position: center bottom; background-repeat: repeat-x; height:150px; } It's a header element with a background image. The problem: This background image arbitrarily appears and disappears when reloading the page. It is more often missing than it is not. Say you reload the page in your browser ten times in twenty seconds; the image will appear in two instances, and be missing in the 18 others. I would have put this down to server problems, but the weird thing is that when it's missing, the request for the image doesn't appear in Firebug's net tab at all. Even if it were cached, the request should be there, shouldn't it? Raw screenshots of the identical page on two reloads: I am 100% sure the CSS file does not change in between. I have examined both instances with Firebug and the CSS is identical. When I change the image's URL by editing the style declaration in firebug to bkg.jpg?xyz=123445 then the image will get loaded, which is making me think this must be a server problem. It happens in both Firefox and Chrome so it must be something basic I'm overlooking. What could be causing a browser not to load a resource at all? I have zero idea about Ruby nor Rails - getting Redmine running and customized is all I have ever had to do with this platform - so I don't really know where to start debugging. Apache's, Mongrel's and Redmine's error logs look fine, though. And then again, this looks like a browser issue. I'm stumped.

  • Using Effect For Fog of War

    - by Qua
    I'm trying to apply fog of war to areas on the screen not currently visible to the player. I do this by rendering the game content in one RenderTarget and the the fog of war into another, and then I merge them with an effect file that takes the color from the game RenderTarget and the alpha from the fog of war render target. The FOW RenderTarget is black where the FOW appears, and white where it doesn't. This does work, but it colors the fog of war (the unrevealed locations) white instead of the intended color of black. Before applying the effect I clear the backbuffer of the device to white. When I try to clear it to black, non of the fog of war appears at all, which I assume is a product of alpha blending with black. It works for all other colors, however - giving the resulting screen a tint of that color. How do I archieve a black fog while still being able to do alpha blending between the two render targets? The rendering code for applying the FOW: private RenderTarget2D mainTarget; private RenderTarget2D lightTarget; private void CombineRenderTargetsAndDraw() { batch.GraphicsDevice.SetRenderTarget(null); batch.GraphicsDevice.Clear(Color.White); fogOfWar.Parameters["LightsTexture"].SetValue(lightTarget); batch.Begin(SpriteSortMode.Immediate, BlendState.AlphaBlend); fogOfWar.CurrentTechnique.Passes[0].Apply(); batch.Draw( mainTarget, new Rectangle(0, 0, batch.GraphicsDevice.PresentationParameters.BackBufferWidth, batch.GraphicsDevice.PresentationParameters.BackBufferHeight), Color.White ); batch.End(); } The effect file I'm using to apply the FOW: texture LightsTexture; sampler ColorSampler : register(s0); sampler LightsSampler = sampler_state{ Texture = <LightsTexture>; }; struct VertexShaderOutput { float4 Position : POSITION0; float2 TexCoord : TEXCOORD0; }; float4 PixelShaderFunction(VertexShaderOutput input) : COLOR0 { float2 tex = input.TexCoord; float4 color = tex2D(ColorSampler, tex); float4 alpha = tex2D(LightsSampler, tex); return float4(color.r, color.g, color.b, alpha.r); } technique Technique1 { pass Pass1 { PixelShader = compile ps_2_0 PixelShaderFunction(); } }

  • In Ruby, how to I read memory values from an external process?

    - by grg-n-sox
    So all I simply want to do is make a Ruby program that reads some values from known memory address in another process's virtual memory. Through my research and basic knowledge of hex editing a running process's x86 assembly in memory, I have found the base address and offsets for the values in memory I want. I do not want to change them; I just want to read them. I asked a developer of a memory editor how to approach this abstract of language and assuming a Windows platform. He told me the Win32API calls for OpenProcess, CreateProcess, ReadProcessMemory, and WriteProcessMemory were the way to go using either C or C++. I think that the way to go would be just using the Win32API class and mapping two instances of it; One for either OpenProcess or CreateProcess, depending on if the user already has th process running or not, and another instance will be mapped to ReadProcessMemory. I probably still need to find the function for getting the list of running processes so I know which running process is the one I want if it is running already. This would take some work to put all together, but I am figuring it wouldn't be too bad to code up. It is just a new area of programming for me since I have never worked this low level from a high level language (well, higher level than C anyways). I am just wondering of the ways to approach this. I could just use a bunch or Win32API calls, but that means having to deal with a bunch of string and array pack and unpacking that is system dependant I want to eventually make this work cross-platform since the process I am reading from is produced from an executable that has multiple platform builds, (I know the memory address changes from system to system. The idea is to have a flat file that contains all memory mappings so the Ruby program can just match the current platform environment to the matching memory mapping.) but from the looks of things I'll just have to make a class that wraps whatever is the current platform's system shared library memory related function calls. For all I know, there could already exist a Ruby gem that takes care of all of this for me that I am just not finding. I could also possibly try editing the executables for each build to make it so whenever the memory values I want to read from are written to by the process, it also writes a copy of the new value to a space in shared memory that I somehow have Ruby make an instance of a class that is a pointer under the hood to that shared memory address and somehow signal to the Ruby program that the value was updated and should be reloaded. Basically a interrupt based system would be nice, but since the purpose of reading these values is just to send to a scoreboard broadcasted from a central server, I could just stick to a polling based system that sends updates at fixed time intervals. I also could just abandon Ruby altogether and go for C or C++ but I do not know those nearly as well. I actually know more x86 than C++ and I only know C as far as system independent ANSI C and have never dealt with shared system libraries before. So is there a gem or lesser known module available that has already done this? If not, then any additional information as to how to accomplish this would be nice. I guess, long story short, how do I do all this? Thanks in advance, Grg PS: Also a confirmation that those Win32API calls should be aimed at the kernel32.dll library would be nice.

  • Unable to verify body hash for DKIM

    - by Joshua
    I'm writing a C# DKIM validator and have come across a problem that I cannot solve. Right now I am working on calculating the body hash, as described in Section 3.7 Computing the Message Hashes. I am working with emails that I have dumped using a modified version of EdgeTransportAsyncLogging sample in the Exchange 2010 Transport Agent SDK. Instead of converting the emails when saving, it just opens a file based on the MessageID and dumps the raw data to disk. I am able to successfully compute the body hash of the sample email provided in Section A.2 using the following code: SHA256Managed hasher = new SHA256Managed(); ASCIIEncoding asciiEncoding = new ASCIIEncoding(); string rawFullMessage = File.ReadAllText(@"C:\Repositories\Sample-A.2.txt"); string headerDelimiter = "\r\n\r\n"; int headerEnd = rawFullMessage.IndexOf(headerDelimiter); string header = rawFullMessage.Substring(0, headerEnd); string body = rawFullMessage.Substring(headerEnd + headerDelimiter.Length); byte[] bodyBytes = asciiEncoding.GetBytes(body); byte[] bodyHash = hasher.ComputeHash(bodyBytes); string bodyBase64 = Convert.ToBase64String(bodyHash); string expectedBase64 = "2jUSOH9NhtVGCQWNr9BrIAPreKQjO6Sn7XIkfJVOzv8="; Console.WriteLine("Expected hash: {1}{0}Computed hash: {2}{0}Are equal: {3}", Environment.NewLine, expectedBase64, bodyBase64, expectedBase64 == bodyBase64); The output from the above code is: Expected hash: 2jUSOH9NhtVGCQWNr9BrIAPreKQjO6Sn7XIkfJVOzv8= Computed hash: 2jUSOH9NhtVGCQWNr9BrIAPreKQjO6Sn7XIkfJVOzv8= Are equal: True Now, most emails come across with the c=relaxed/relaxed setting, which requires you to do some work on the body and header before hashing and verifying. And while I was working on it (failing to get it to work) I finally came across a message with c=simple/simple which means that you process the whole body as is minus any empty CRLF at the end of the body. (Really, the rules for Body Canonicalization are quite ... simple.) Here is the real DKIM email with a signature using the simple algorithm (with only unneeded headers cleaned up). Now, using the above code and updating the expectedBase64 hash I get the following results: Expected hash: VnGg12/s7xH3BraeN5LiiN+I2Ul/db5/jZYYgt4wEIw= Computed hash: ISNNtgnFZxmW6iuey/3Qql5u6nflKPTke4sMXWMxNUw= Are equal: False The expected hash is the value from the bh= field of the DKIM-Signature header. Now, the file used in the second test is a direct raw output from the Exchange 2010 Transport Agent. If so inclined, you can view the modified EdgeTransportLogging.txt. At this point, no matter how I modify the second email, changing the start position or number of CRLF at the end of the file I cannot get the files to match. What worries me is that I have been unable to validate any body hash so far (simple or relaxed) and that it may not be feasible to process DKIM through Exchange 2010.

  • Jquery Dialog - div disappears after initialization

    - by Zuber
    JQuery Dialog is giving me lots of pain lately. I have the following div which I want to be popped up. (Ignore that the classes do not show the double quotes in the syntax) TABLE class=widget-title-table border=0 cellSpacing=0 cellPadding=0> <TBODY> <TR> <TD class=widget-title><SPAN class=widget-title>Basic Info</SPAN></TD> <TD class=widget-action> <DIV id=edit-actions jQuery1266325647362="3"> <UL class="linkbutton-menu read-mode"> <LI class="control-actions"> <A id="action-button" class="mouse-over-pointer linkbutton">Delete this stakeholder</A> <DIV id="confirmation" class="confirmation-dialog title=Confirmation"> Are you sure you want to delete this stakeholder? </DIV> </LI></UL></DIV></TD></TR></TBODY></TABLE> The JQuery for this is ... $(document).ready(function() { $('#confirmation').dialog({ bgiframe: true, modal: true, autoOpen: false, closeOnEscape: false, draggable: true, position: 'center', resizable: false, width: 400, height: 150 }); }); And the dialog is 'open'ed by var confirmationBox = $('#confirmation',actionContent); if (confirmationBox.length > 0) { //Confirmation Needed $(confirmationBox).dialog('option', 'buttons', { 'No': function() { $(this).dialog('close'); }, 'Yes': function() { $('ul.read-mode').hide(); $.post(requestUrl, {}, ActionCallback(context[0], renderFormUrl), 'json'); $(this).dialog('close'); } }); $(confirmationBox).dialog('open'); } The problem starts in the initialization itself. When the document loads, the <div #confirmation> is deleted from the markup! I had a similar issue earlier, but I cannot use that solution here. On this page I can have multiple PopUp divs. When I added the initialization in just before opening it; the form popped up. But after I close it, the div is removed; so I am not able to see the popup again.

  • ASP.Net master page scrollbar question

    - by Stephen Falken
    Like happens to all of us sometimes, I inherited some crappy code I have to fix. We need to center our pages on widescreen machines, so we have a master page layout div like so: .MasterLayout { width:1100px; height: 100%; position:absolute; left:50%; margin-left:-550px; vertical-align:top; } I removed most of the detailed attributes for readability here, but here's how the table for the master page is laid out: <table border="0" cellpadding="0" cellspacing="0" style="width: 100%;"> <tr> <td style="width: 100%" align="center" colspan="2"> </td> </tr> <tr> <td colspan="2" style="height: 20px; background-color: #333;"> <asp:SiteMapPath/> </td> </tr> <tr> <td style="width: 86px; height: 650px; background-color: #B5C7DE; margin: 6px;" valign="top"> <asp:Menu /> <asp:SiteMapDataSource /> </td> <td style="background-color:#ffffff; margin:5px; width:1000px;" valign="top"> <asp:contentplaceholder id="ContentPlaceHolder1" runat="server"/> </td> </tr> </table> When resizing the browser window, the horizontal scrollbar only reaches as far as the left edge of the <asp:contentplaceholder/> control, and the <asp:menu/> that's in the 86px wide <td> is hidden. How can I fix this problem? THANKS IN ADVANCE

  • Volunteer for a potential employer?

    - by EoRaptor013
    I've been looking for work since March, and haven't had much luck. Recently, however, I interviewed with a small company near my home for a C#, .NET, SQL development position. I hit it off very well with the hiring manager during the phone screen, and even more so during the face to face. Unfortunately, I failed the practical test: wiring up a web form, creating a couple of SQL stored procedures, saving new data with validation, and creating a minimal search screen. I knew what I was doing, but I was too slow to meet their standards as all the work needed to be done within an hour. Nevertheless, I really liked the place, the environment, the people who I would have been working with, and the boss. (I gave the company an 11 on Joel's 12 point scale.) So, the obvious next step was to scrape the rust off. I've been trying to create little projects for myself, but I don't know that I've been effective in getting any faster. What with all that goes into creating a project, I'm not heads-down coding as much as I think I need. Now, with all that introduction, here's the question. I have been thinking about calling the hiring manager at that place, and asking him to let me volunteer for three or four weeks, with no strings attached. I think it would benefit me, and wouldn't cost him anything (as long as I didn't slow the existing people down!). At the end of that period, he might, or might not, be inclined to hire me, but even if not, I would have had as much as 160 hours of in the trenches development. Maybe not all shiny, but no more rust, I would think. Does this plan make any sense at all? I certainly don't want to sound desperate (although, I'm not far from being there), and I very much need the tuneup, lube, and change the oil. What's the downside, if any, to me doing this? Do any of you see red flags going up—either from the prerspective of the hiring manager, or from the perspective of a developer?
