  • How to access xmlParserCtxt structure from within xmlSAXHandler callbacks?

    - by Lux In Tenebris
    I'm parsing (X)HTML pages content with libxml using the following call: htmlDocPtr doc = htmlSAXParseDoc(content, NULL, &html_handler, NULL); But for debugging purposes I need to analyze some of the current node properties in the start/end element callbacks. I know that the fourth argument of htmlSAXParseDoc can be used to pass any user defined data to the callbacks, but I don't have a pointer to xmlParserCtxt.

  • Use of RegularExpressionValidator in MS .Net Framework

    - by Lawk Salih
    Hi- I am trying to use the RegularExpressionValidator Control in Visual Studio to validate a textbox for email address expressions. Here's my code (very basic) Email:&nbsp; <input id="Text1" type="text" /><br /> <br /> <input id="Validate" type="button" value="Validate" runat="server" /><br /> <br /> <asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server" ErrorMessage="RegularExpressionValidator" ControlToValidate="Validate" ValidationExpression="\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*"></asp:RegularExpressionValidator> Now, when I set controlToValidate to Validate, I get the following error message: Server Error in '/' Application.

  • Livevalidation clientside validation - can you control the position of the validation messages?

    - by JK
    I'm using LiveValidaion for my clientside validation http://livevalidation.com/ and DataAnnotations for my validation rules. This all works fine except that the clientside error messages are only ever displayed to the right of the element being validated. Is it possible to move this validation message below the element being validated? Or even better, group all messages in a div at the top/bottom of the page? I dont see anything in their docs or examples

  • Linq to SQL: how get row security between write access??

    - by Francisco
    I would like to allow two threads to write in a table at the same time (I know the problem of updating the same row, but this would be a story apart). I need that in behalf of speed up the operations in my aplication (one thread could write in row X while another could do the same in row X+n instead of waiting the first to finalize). So, can I block rows instead of tables with Linq to SQL? Thanks.

    I was wondering is it possible to get a notification of when a new configured network is added to the WifiManager in Android? I know you can get the current list of configured networks getConfiguredNetworks But is it possible to get notification of when a new one is added? I dont see anything in the WifiManager that would be helpful. Has anyone any other ideas? Or insight into how this could be achieved?

  • Where does the delete control go in my Cocoa user interface?

    - by Graham Lee
    Hi, I have a Cocoa application managing a collection of objects. The collection is presented in an NSCollectionView, with a "new object" button nearby so users can add to the collection. Of course, I know that having a "delete object" button next to that button would be dangerous, because people might accidentally knock it when they mean to create something. I don't like having "are you sure you want to..." dialogues, so I dispensed with the "delete object". There's a menu item under Edit for removing an object, and you can hit Cmd-backspace to do the same. The app supports undoing delete actions. Now I'm getting support emails ranging from "does it have to be so hard to delete things" to "why can't I delete objects?". That suggests I've made it a bit too hard, so what's the happy middle ground? I see applications from Apple that do it my way, or with the add/remove buttons next to each other, but I hate that latter option. Is there another good (and preferably common) convention for delete controls? I thought about an action menu but I don't think I have any other actions that would go in it, rendering the menu a bit thin.

  • Strict pointer aliasing: is access through a 'volatile' pointer/reference a solution?

    - by doublep
    On the heels of a specific problem, a self-answer and comments to it, I'd like to understand if it is a proper solution, workaround/hack or just plain wrong. Specifically, I rewrote code: T x = ...; if (*reinterpret_cast <int*> (&x) == 0) ... As: T x = ...; if (*reinterpret_cast <volatile int*> (&x) == 0) ... with a volatile qualifier to the pointer. Let's just assume that treating T as int in my situation makes sense. Does this accessing through a volatile reference solve pointer aliasing problem? For a reference, from specification: [ Note: volatile is a hint to the implementation to avoid aggressive optimization involving the object because the value of the object might be changed by means undetectable by an implementation. See 1.9 for detailed semantics. In general, the semantics of volatile are intended to be the same in C++ as they are in C. — end note ] EDIT: The above code did solve my problem at least on GCC 4.5.

  • How to get global access to enum types in C#?

    - by lala
    This is probably a stupid question, but I can't seem to do it. I want to set up some enums in one class like this: public enum Direction { north, east, south, west }; Then have that enum type accessible to all classes so that some other class could for instance have: Direction dir = north; and be able to pass the enum type between classes: public void changeDirection(Direction direction) { dir = direction; } I thought that setting the enum to public would make this automatically possible, but it doesn't seem to be visible outside of the class I declared the enum in.

  • ASP.NET: I'm getting strange output when styling a Label control...

    - by pkiyan
    .labelOne { border-width:thin; border-style:solid; border-color:Red; background-color:Silver; } <asp:Label ID="Label1" runat="server" CssClass="labelOne"> <h1>Hello world</h1> </asp:Label> <br /><br /> <asp:Label ID="Label2" runat="server" BorderColor="Black" BorderStyle="Solid" BorderWidth="1px" BackColor="Silver"> <h1>Hello world</h1> </asp:Label> Hello. In the code sample above I have 2 Label controls with their contents set to an h1 header tag. The first Label is styled using css, and the second with the Label's inline properties (both Labels have identical styling). But the first Label doesn't output properly, it's border is broken. If I replace the first Label's markup with plain "Hello world" text it renders properly, but it breaks again when I use markup. Can someone explain why this is happening?

  • Is it possible to programmatically control c# health monitoring without using the web.config file?

    - by Adam
    I have developed my own custom provider for the health monitoring; however, I use parameters in the constructor and this is not allowed when using the health monitoring from the web.config file. Does anyone know if I can turn on/off the monitoring and have it watch properly through code (possibly in my global.asax file on application startup). Or, is it possible for me to create my own watcher that will do the same thing as the health monitor. Or, finally - can I just pass variables from the web.config setup (i'm not familiar with the public token part of the provider type declaration). Thanks in advance

  • mvc create my own html helper, how can i access httpcontext?

    - by rj
    Hi, I've come across two recommendations for creating custom html helpers: either extend an existing one, or write your own class. I'd prefer to keep my custom code separated, it seems a bit sloppy to extend helpers for a decent-size application. But the benefit I see in extending is that 'This HtmlHelper helper' is passed as a parameter, through which I can get ViewContext.HtmlContext. My question is, how can I roll my own helper class and still have ViewContext.HtmlContext available to me? Thanks!

  • How can I trigger a transition effect when a child control is added or removed in flex?

    - by Jason Towne
    I've got a custom component that has children components dynamically added and removed to it depending on what button the user clicks. What I would like to do is trigger a transition effect that moves the child component onto the stage when it's added and then moves it off when it's removed. Does anyone have a good example on how to accomplish this? Edit: I figured it out and left my solution below. I hope it helps someone else!

  • In FLEX, How can you stop ENTER Key from my Alert being caught by the control that initiated the Al

    - by WeeJavaDude
    I am having an issue where I show an AlertBox message when the user hits ENTER and the focus is in a text area. The pop up works fine, but when the user hits enter the Alert closes as expected, but the TextArea listener receives the ENTER event from the Alert and pops the dialog up again. I have tried a number of ways to catch and eat the event but so far I have not been lucky. Is there way to accomplish this? public function init():void { myTextInput.addEventListener(KeyboardEvent.KEY_UP, handleKeyStrokes); } public function handleKeyStrokes(evt:KeyboardEvent):void { if(evt.keyCode == Keyboard.ENTER) { myAlert = Alert.show("This is a test and only a test", "Title", 4, null, alertCallBack); } } <mx:TextInput id="myTextInput" left="600" top="10"> </mx:TextInput>

  • NHibernate: Can I access a generated primary key after saving a model?

    - by littlecharva
    Howdy, So I've got a simple table with an ID field that's incrementally generated on INSERT. I've set the mapping up in NHibernate to reflect this: <id name="ID"> <generator class="identity" /> </id> And it all works fine. Trouble is, I need to get the generated ID after I've saved a new model to use elsewhere: var model = new MyModel(); session.SaveOrUpdate(model); But at this stage model.ID == null, not the ID. Any ideas? Anthony
