• How to create a valid schema in a WSDL that restrict to <|<=|>|>=

  - by wsxedc

  This is what I have in my schema section of my WSDL to specify the field has to be comparison operators <xsd:simpleType> <xsd:restriction base="xsd:string"> <xsd:pattern value="&lt;|&gt;|&lt;=|&gt;=|="/> </xsd:restriction> </xsd:simpleType> SoapUI complains about this part of the WSDL, I tried to set the value to something with non special characters and the WSDL is valid. So I tried to replace that whole long string to be value=">gt;" and it valid but value="<lt;" is not valid, and value=">" is also not valid. My question is, why does the WSDL validation need > to be double escaped? The main question is, how to provide a valid less than side within the pattern value.

• Is there another way to integrate PDF viewing in a Flex application?

  - by BCunningham

  I'm looking at ways to embed PDF viewing in a Flex application. Currently the only option I've seen is by using the flash.html.HTMLLoader class, which only works if you're using AIR. This isn't a big deal -- I'm willing to use AIR if I have to -- but based on my experimentation with viewing a PDF this way it appears that AIR simply integrates the embedded Adobe PDF browser Plug-in for viewing, which not only shows the PDF page(s), but provides all of the manipulation controls as well (zooming, printing, etc.) which I don't want to see. I'm looking for something that works somewhat along the lines of the JPedal library for Java -- an embedded component that simply renders the PDF alone. Has anyone found a way to do this with either AIR's built-in component or via some other method?

• How to Validate an XML Node against an XSD in C++?

  - by Ashish

  Hi Please note that I'm asking for validation against a particular node and not the whole file. For examples <somexmldoc> <someNode> <UserDefinedNode> </> <UserDefinedNode> </> </someNode> </somexmldoc> For this XML doc, I have an wholeDoc.XSD which could be used to validate the whole document except "UserDefinedNode" (This node is specified with "any" tag in xsd, which allows a user to define anything under that node). Is it possible to have a separate userdefined.XSD file to validate "UserDefinedNode"? Is it possible to use MSXML for C++ (IXMLDomDocument) to validate this? Thanks!

• ASP.NET MVC 2 project default script files. What do you use?

  - by Andrew Florko

  Many js files are included into Scripts folder by default in ASP.NET MVC 2 Projects. I suppose developers use jquery library nearly every time they program a site, but what about other files? Please, can you tell scenarios and reasons when you: Use Microsoft.Ajax instead of jquery or mix both libraries? Do you use JQuery validation infrastructure instead of asp.net mvc one, or combine them both? Thank you in advance! P.S. there are also diferrent editions of the same file. Do you include different editions depenending on debug/release build?

• Your opinion on the best jquery book

  - by Seattle Leonard

  Hello all, I'm looking to purchase a jquery book. I'm a strong C# developer whose had experience with dojo. Now, I'm building my own site and am looking to learn a new platform in the process. So, I've chosen jquery. With dojo, I know how to make my own widgets. I want to learn about ways to plug into jquery to make reusable controls. Also, I plan to make heavy use of json with ajax. Other things to consider: I would call my javascript expertise as intermediate. I'd like to find a book that is as up to date with the jquery platform as possible as I know that in a few months it will likely be out of date. What book or books would you reccomend?

• Rails3 Redirect for javascript/ajax

  - by Tiago

  Hi, I'm using a form with the remote => true. I have a validation that is working correctly. My problem is when the user enters all the correct information and writes the data at this time I do a redirect to the page of the show. Instead of redirecting, it displays the html of the show in my div. How can I make a javascript redirect that will understand? I did not want to use the window.location. Thanks...

  Hi If you go to http://ifdefined.com/btnet/bugs.aspx you will see a long list of sample data in an asp.net gridview control. What I need to do is something similar. I need to implement the filtering system by placing dropdown controls with dynamic values on the headers and then filter the record according to them. If you look carefully they are filtering the data based on multiple drodown selections as well. Kindly help me out. Any kind of input is highly appreciated. Thanks in advance for your time.

• how to protect an imported win32 dll into a .net application from memory issues

  - by Eric

  I have a c# application that needs to use a legacy win32 dll. The dll is almost its own app, it has dialogs, operations with hardware, etc. When this dll is imported and used, there are a couple of problems that occur: Dragging a dialog (not a windows system dialog, but one created by the dll) across the managed code app causes the UI to not repaint. Further it generates a system out of memory exception from various ui controls. The performance is incredibly slow. There seems to be no way to unload the dll so the memory never gets cleaned up. When we close our managed app, we get another memory exception. At the moment we import each method call as such: [DllImport("dllname.dll", EntryPoint = "MethodName", SetLastError = true, CharSet = CharSet.Auto, ExactSpelling = true, CallingConvention = CallingConvention.StdCall)]

• ASP.NET Server.Execute

  - by justin

  I'm having some problems with Server.Execute that I can't seem to find any details on. Page page = new WidgetProcessor(Widget); Server.Execute(page, htmlTextWriter, true); The Widget in the above code is a simple object that knows how to instantiate a usercontrol. The WidgetProcessor takes a Widget and adds the widgets control to the page. This works fine on the initial load, it doesn't seem to handle postbacks however; it never actually fires the user controls events, it just consistently returns the original page as if you had never posted back. I've found this article from 2003: http://support.microsoft.com/kb/817036, though I would think they would have fixed this by now. Any help would be appreciated.

• How to draw or put a text on empty an UITableViewController ?

  - by elementsense

  Hi I have a app that starts with a empty UITableViewController, which is pretty .. well, emtpy. Now I was wondering if I could hint the user by painting something else on the view, like pointing an arrow to the plus button and say something like "press here to add something new" I'll guess I have to do this in the viewDidLoad method, where I also init my NSFetchedResultsController, so I actually know if there are any objects in my list. I never put controls on the screen by code so I am not sure where to start and where to put em on. will that be the [self view] ? Thanks

• Silverlight Memory Usage

  - by peter

  Hi All, Is there a way to measure the current memory usage of the silverlight plug-in from within the client side C# code? I am isolating a memory leak and it would be good to know the current memory usage of the plug-in. For instance it could be logged to a file before I clicked a button that it was using '60 mb' and after I clicked the button it was using '70 mb' etc. I could then gradually add in controls and use this technique to quantify the leak. Thanks.

• Tracking changes to individual fields - Silverlight

  - by Appu

  I have a page which has got several text boxes. These controls are bound to a model. I am using MVVM. Assume I have three text boxes, FirstName, LastName and Company. So in the model, I have three properties to bind. Now I need to track the changes happened to each field. If FirstName changes from original value, I need the text box to be colored with a different background color. Currently I am creating another property called FirstNameChanged and binding the background to this property. This will be updated when I change the FirstName. For 3 fields, this seems to be OK. But when I have more fields, the number of properties will be too much. Is there a better way to handle this?

• How to expose a control collection to a property grid at design time

  - by Stefano Delendati

  I have a custom control that with a property that is a collection of custom object. This custom object hava a reference to some component/controls. When at design time I tray to add an item to the collection and select the object, VS tells me that the control is not serializable. This is the code (simplified version - but not to much): public class ViewRefObj { public control view { get; set; } public ViewRefObj() { } } private List<ViewRefObj> _controls=new List<ViewRefObj>(); public List<ViewRefObj> Views { get { return _controls; } }

• PHP CURL works fine from localhost not from server

  - by Joby Joseph

  I have 2 servers, srv1 and srv2. All client sites are stored in srv2 and all authentication details are stored in srv1. Each time a client site is loaded, the site in srv2 sends a curl request to srv1 to validate. I am always getting bool(false) when I print the curl response using var_dump. But if I am requesting for validation from my local wamp installation(localhost) it is perfectly returning the response. According to my understanding srv2 is blocking srv1 ip or something like that. Any help or suggestions will be greatly appreciated. The solution is really urgent as all my clients are stuck with invalid authorization message. Edit: Now when i tested curl in srv2 is working fine i think. Because I am able to fetch other websites without any trouble. But I am not able to fetch data from srv1. I can view a page from srv1 through browser url but not through curl.

• Is this the correct why of speaking to a "Content Manager" Class?

  - by DeanMc

  I am creating a silverlight site. I am currently breaking out my ideas into pieces of functionality. One of the idea's I have is the concept of a content manager. This is essentially a UI control with 4 regions. Top, Bottom, Right & Left. I also have a collection of objects that are considered "Menu Items". These are controls that function as a way to navigate around, similar to links. The idea I have is to implement an IMenuItem interface. Among the standard pieces of information (Text, PageReference, etc) I was also going to hold a reference to the content manager. My idea behind this thinking is that I can pass the PageReference to a property on the ContentManager and then call a method which knows how to update the content manager accordingly. Is this the best way of implementing this or is their some sort of pattern for it?

• How to generate random strings that match a given regexp?

  - by Pies

  Duplicate: Random string that matches a regexp No, it isn't. I'm looking for an easy and universal method, one that I could actually implement. That's far more difficult than randomly generating passwords. I want to create an application that takes a regular expression, and shows 10 randomly generated strings that match that expression. It's supposed to help people better understand their regexps, and to decide i.e. if they're secure enough for validation purposes. Does anyone know of an easy way to do that? One obvious solution would be to write (or steal) a regexp parser, but that seems really over my head. I repeat, I'm looking for an easy and universal way to do that. Edit: Brute force approach is out of the question. Assuming the random strings would just be [a-z0-9]{10} and 1 million iterations per second, it would take 65 years to iterate trough the space of all 10-char strings.

• What to do with lookup entities selected from drop down select ? How to send them to the service lay

  - by arrages

  I am developing a spring mvc based application. I have a simple pojo form object, the problem is that many properties will be taked from drop down lists that are populated from lookup entities, so I return the entity ID to the form object. public NewCarRequestForm { private makeId; // this are selected from a drop down. private modelId; } Should I just send this lookup entity ID to the service layer? or should I validated that this ID is correct (Somebody can send any random ID through the request) before and how? Now there is a problem if I want to validated something based on some property of the lookup entity. Do I perform a database lookup of the entity just to perform the validation? thanks.

• ASP.net hiding panel using javascript

  - by Zaps

  Hi, I have a radioButtonList with 2 items in it. A radiobutton with a "Yes" value and a radionButton with a "No" value. Below that I have a panel which I want made visible when "Yes" radioButton is selected and hidden when "No" is selected. I had originally implemented this using the AutoPostBack attribute but I want to do it in Javascript so that it doesn't cause a postback. Here's the code.

• jquery ui-effects-wrapper causing havoc

  - by vondip

  Hi all, I am using jquery-ui and at some point I use the show and hide functions quite heavily to animate changing images coming in and out. From some reason, after a few tries all of a sudden the controls on my page stop responding to clicks. After a bit of poking arround using firebug I discovered my page is filled with div's of the class ui-effects-wrapper. I have no idea why this happens or how to stop it. If I remove these divs I can no longer see the images I've been animating. Any ideas?
