  • Select only items in a specific DIV using HtmlAgilityPack

    - by Adam Haile
    I'm trying to use the HtmlAgilityPack to pull all of the links from a page that are contained within a div declared as <div class='content'> However, when I use the code below I simply get ALL links on the entire page. This doesn't really make sense to me since I am calling SelectNodes from the sub-node I selected earlier (which when viewed in the debugger only shows the HTML from that specific div). So, it's like it's going back to the very root node every time I call SelectNodes. The code I use is below: HtmlWeb hw = new HtmlWeb(); HtmlDocument doc = hw.Load(@"http://example.com"); HtmlNode node = doc.DocumentNode.SelectSingleNode("//div[@class='content']"); foreach(HtmlNode link in node.SelectNodes("//a[@href]")) { Console.WriteLine(link.Value); } Is this the expected behavior? And if so, how do I get it to do what I'm expecting?

  • How do I get a bundle reference from inside of a plugin with carbon?

    - by Nik Reiman
    I'm writing a C++ plugin in Mac OS X using the Carbon framework (yeah, yeah, I know, Apple is deprecating Carbon, but at the moment I can't migrate this code to Cocoa). My plugin gets loaded by a master application, and I need to get a CFBundleRef reference to my plugin so that I can access it's resources. The problem is, when I call CFBundleGetMainBundle() during my plugin's initialization routines, that returns a reference to the host's bundle reference, not the plugin's. How can I get a reference to my plugin's bundle instead? Note: I would rather not use anything determined at compile-time, including calling CFBundleGetBundleWithIdentifier() with a hard-coded string identifier.

  • Presenting a Popover From a Rect Problem

    - by Sheehan Alam
    I have a UITableViewCell that has some labels and images that can be clicked. I want to present a popover whenever a user clicks on any part of the cell. How can I achieve this without interfering with the click actions of the labels & images? I am currently creating an invisible button ontop of some other clickable items in the cell and calling the popover: [replyPopover presentPopoverFromRect:CGRectMake(77, 25, 408, 68) inView:self permittedArrowDirections: UIPopoverArrowDirectionDown animated:YES]; Unfortunately, because the button is on top of the labels & images I am unable to click them. How can I show a popover by clicking on the background of a cell, so that there is no interference when clicking images & labels inside the cell?

  • How to fetch message body and attachments in XML format using php/linux from Lotus Domino server?

    - by too
    Has anybody some information about accessing Lotus Domino server to fetch entire mail contents by http(s) requests from php linux server? The article by Andrei Kouvchinnikov describes well how to fetch message list in notes mail folders; after obtaining session id during login one can for example select top 100 messages by calling: https://your.server.domain/mail_db/mailbox.nsf/($Inbox)?ReadViewEntries&Start=1&Count=100 And this works perfectly. The problem arises when I am trying to get message contents (0A1DA5EEB7B65277C12576F50055D811 is an example message unique Id): https://your.server.domain/mail_db/mailbox.nsf/($Inbox)/0A1DA5EEB7B65277C12576F50055D811/?OpenDocument Such request in IE shows frameset with data hard to parse, in less common browsers like Opera it informs about unsupported browser. Ideally if it is possible to fetch notes message contents and all attachments by requesting it in the url, has anybody some information what request would it be? Link to Lotus web calls reference would be even more beneficial.

  • Rails 3 - Nested layouts - LocalJumpError

    - by Art Shayderov
    Hi Nested layouts do not work in Rails 3. After I hit this I tried Rails Guides Example on a blank project (both ruby 1.9.1 and 1.8.7). LocalJumpError no block given on line <%= yield :stylesheets %. If you remove this line you will get the same error on the next yield statement. Could someone fix(patch) this? It's probably just a matter of calling block_given? in the right place. That would be great. Thanks Added on 4/3: Rails 3 beta 2 released. Problem fixed.

  • Abstract out repeated code

    - by CookieMonster
    The code in this event is repeated exactly in two other event handlers. How do I put the repeated code into a method and call that method from the event handlers so I only have to maintain it in one place? I'm not sure how to pass the event args to the calling method. protected void gvDocAssoc_RowDataBound(object sender, GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { if ((Convert.ToString(DataBinder.Eval(e.Row.DataItem, "DETAIL_TYPE_DESC")) == "Transcript") && (Convert.ToString(DataBinder.Eval(e.Row.DataItem, "INSTITUTION_CODE")) == "")) { e.Row.BackColor = System.Drawing.Color.Red; } if ((Convert.ToString(DataBinder.Eval(e.Row.DataItem, "DETAIL_TYPE_DESC")) == "Certified Diploma") && (Convert.ToString(DataBinder.Eval(e.Row.DataItem, "INSTITUTION_CODE")) == "")) { e.Row.BackColor = System.Drawing.Color.Red; } if ((Convert.ToString(DataBinder.Eval(e.Row.DataItem, "DOC_TYPE_DESC")) == "Post Graduate conditions") && (Convert.ToString(DataBinder.Eval(e.Row.DataItem, "INSTITUTION_CODE")) == "")) { e.Row.BackColor = System.Drawing.Color.Red; } } }

  • jQuery plugin: Colorpicker

    - by New Developper
    Hey all, I'm using this colorpicker (http://www.eyecon.ro/colorpicker) and am trying to capture the hex value so that I can use it on the server side to store the selected color. If you check out the link provided, I'm using the last option: $('#colorSelector').ColorPicker({ color: '#0000ff', onShow: function (colpkr) { $(colpkr).fadeIn(500); return false; }, onHide: function (colpkr) { $(colpkr).fadeOut(500); return false; }, onChange: function (hsb, hex, rgb) { $('#colorSelector div').css('backgroundColor', '#' + hex); } }); My problem is that I can't seem to get the hex value from it...I've tried simply calling the name of the input to get its value, but it won't work (when you click away to make the colorpicker disappear, the input changes to 'style="display:none;"' so I can't get anything from it. Then, I tried pulling the value using some simple jQuery calls, but got nothing... Please help....

  • is it possible to mix DHTML and Applet for Drag and drop?

    - by indra
    I am working on some example to find if a Div (DHTML) on to Java Applet in a web page. I used YUI JS Drag drop library to make the div as droppable item and made the div surrounding the Applet as Drop Target. When I dropped it in the Div containing Applet, I am Calling some method in the applet from Javascript Drop handler? This is fine, but I have the problem if the applet contains different objects and regions , how to identify which object it is dropped on? is there any other approach to work with DHTML and applets for Drag and Drop? Also, is it possible to write DD between two applets? Thanks in advance.

  • How do I call exec in psake to an executable with a variable path?

    - by Josh Kodroff
    I can't seem to call this executable correctly in my psake deploy script. If I do this: exec { "$ArchiverOutputDir\NServiceBus.Host.exe /install" } It simply outputs this (and is clearly not calling the executable - just outputting the value of that expression): c:\ReloDotNet2_ServiceEndpoints\Archiver\NServiceBus.Host.exe /install But if I do this: exec { c:\ReloDotNet2_ServiceEndpoints\Archiver\NServiceBus.Host.exe /install } I get the expected output from the executable. How do I correctly call an executable with a variable in the path to the executable in psake? If this is actually a PowerShell issue, please feel free to correct the question to reflect that insight.

  • EF problem with entity re-ordering and uniqueness constraint

    - by wpfwannabe
    I am using Entity Framework and I've come to an interesting stumbling block. Let's say there is a db table "Item" with "sequence" column of type int (and others of course). Column "sequence" must be unique and it is used for (re)ordering of items. EF maps this table to "Item" class with "sequence" int property. Now let's say I want to swap position of two items by mutually exchanging each other's sequence number. Upon calling SaveChanges() EF throws an exception complaining about "sequence" uniqueness. It probably generates two UPDATEs and the first one probably fails. I assume that plain SQL solution to this issue is using a third UPDATE to introduce a unique sequence value in the process but I am stuck with EF. Any thoughts?

  • Reflection.Emit: How to convert MethodBuilder to RuntimeMethodInfo reliably?

    - by Qwertie
    After generating a type dynamically and calling TypeBuilder.CreateType, I want to create a delegate that points to a method in the new type. But if I use code like loadedType = typeBuilder.CreateType(); myDelegate = (MyDelegate)Delegate.CreateDelegate( typeof(MyDelegate), methodBuilder); Reusing the methodBuilder as a methodInfo, I get the exception "MethodInfo must be a RuntimeMethodInfo". Now normally I can re-acquire the MethodInfo with MethodInfo mi = loadedType.GetMethod(methodBuilder.Name); myDelegate = (MyDelegate)Delegate.CreateDelegate(typeof(MyDelegate), mi); But my class may contain several overloaded methods with the same name. How do I make sure I get the right one? Do methods have some persistent identifier I could look up in loadedType?

  • Advantage of using a static member function instead of an equivalent non-static member function?

    - by jonathanasdf
    I was wondering whether there's any advantages to using a static member function when there is a non-static equivalent. Will it result in faster execution (because of not having to care about all of the member variables), or maybe less use of memory (because of not being included in all instances)? Basically, the function I'm looking at is an utility function to rotate an integer array representing pixel colours an arbitrary number of degrees around an arbitrary centre point. It is placed in my abstract Bullet base class, since only the bullets will be using it and I didn't want the overhead of calling it in some utility class. It's a bit too long and used in every single derived bullet class, making it probably not a good idea to inline. How would you suggest I define this function? As a static member function of Bullet, of a non-static member function of Bullet, or maybe not as a member of Bullet but defined outside of the class in Bullet.h? What are the advantages and disadvantages of each?

  • Cannot see changes made to aspx

    - by Senica Gonzalez
    I'm trying to edit an aspx page...mainly javascript, and I randomly see changes that I've made when refreshing. I'm using jquery, but I'm not sure that jquery is the culprit here. For example. If I add a simple alert("hello"); in the page I'm calling, I do not see it take place until I have cleared all my temp files and cache, closed my browser opened back up...and even then, sometimes, I still don't see my changes. Any ideas?

  • Rationale behind Python's preferred for syntax

    - by susmits
    What is the rationale behind the advocated use of the for i in xrange(...)-style looping constructs in Python? For simple integer looping, the difference in overheads is substantial. I conducted a simple test using two pieces of code: File idiomatic.py: #!/usr/bin/env python M = 10000 N = 10000 if __name__ == "__main__": x, y = 0, 0 for x in xrange(N): for y in xrange(M): pass File cstyle.py: #!/usr/bin/env python M = 10000 N = 10000 if __name__ == "__main__": x, y = 0, 0 while x < N: while y < M: y += 1 x += 1 Profiling results were as follows: bash-3.1$ time python cstyle.py real 0m0.109s user 0m0.015s sys 0m0.000s bash-3.1$ time python idiomatic.py real 0m4.492s user 0m0.000s sys 0m0.031s I can understand why the Pythonic version is slower -- I imagine it has a lot to do with calling xrange N times, perhaps this could be eliminated if there was a way to rewind a generator. However, with this deal of difference in execution time, why would one prefer to use the Pythonic version?

  • Is it good practice to call module functions directly in VB.NET?

    - by froadie
    I have a Util module in my VB.NET program that has project-wide methods such as logging and property parsing. The general practice where I work seems to be to call these methods directly without prefixing them with Util. When I was new to VB, it took me a while to figure out where these methods/functions were coming from. As I use my own Util methods now, I can't help thinking that it's a lot clearer and more understandable to add Util. before each method call (you know immediately that it's user-defined but not within the current class, and where to find it), and is hardly even longer. What's the general practice when calling procedures/functions of VB modules? Should we prefix them with the module name or not?

  • iPhone In-App Purchase Store Kit error -1003 "Cannot connect to iTunes Store"

    - by Rei
    Hi all- I've been working on adding in-app purchases and was able to create and test in-app purchases using Store Kit (yay!). During testing, I exercised my app in a way which caused the app to crash mid purchase (so I guess the normal cycle of receiving paymentQueue:updatedTransactions and calling finishTransaction was interrupted). Now I am unable to successfully complete any transactions and instead am getting only transactions with transactionState SKPaymentTransactionStateFailed when paymentQueue:updatedTransactions is called. The transaction.error.code is -1003 and the transaction.error.localizedDescription is "Cannot connect to iTunes Store"! I have tried removing all products from iTunesConnect, and rebuilt them using different identifiers but that did not help. I have also tried using the App Store app to really connect to the real App Store and download some apps so I do have connectivity. Finally, I have visited the Settings:Store app to make sure I am signed out of my normal app store account. Any ideas? -Rei

  • ejb timer service vs cron

    - by darko petreski
    Hi Ejb timer service can start some process in desired time intervals. Also we can do the same thing with cron (min 1 minute) interval. But doing it with cron we have more power on controlling, monitoring and changing the intervals. Also we can restart if needed the cron very easily by command line. Also we can add or remove lines in the cron transparently. What are the advantages of using ejb timer services over calling the ejbs from cron ? (several lines of code in the cron classes are not a problem) Regards.

  • System.WIndows.Application static members are thread safe?

    - by Lirik
    The Application static members are supposed to be thread safe: The public static (Shared in Visual Basic) members of this type are thread safe. In addition, the FindResource and TryFindResource methods and the Properties and Resources properties are thread safe.1 How much can we trust that statement in a multithreaded environment when calling static member methods of System.Windows.Application? Update: It's all in reference to this question: http://stackoverflow.com/questions/2463822/threading-errors-with-application-loadcomponent-key-already-exists/2463866#2463866 I never thought I'd see a real bug in the library, but this must be the day for me... that question seems to show a genuine bug. Usually it's "user error," but this doesn't seem to be the case.

  • UIAlertView crashing on undocumented method

    - by morticae
    Our app has been crashing with a frequency of roughly 1 in 1,500 launches due to a bug that is proving elusive. The relevant portion of the stack trace is included. It's being fired as a callback so I have no reference for where it's occurring in my own code. It looks like what's going on is there is a UIViewAnimationState object that is calling UIAlertView's private method (_popoutAnimationDidStop:finished:). Only problem is, it appears the UIAlertView has been dealloced by this point. I don't do anything weird with alert views. I throw them up, and I wait for user input. They are all shown before being released. Anyone encountered this? At this point, I'm leaning toward it being an Apple bug.

  • Issue with JSON and jQuery

    - by Jason N. Gaylord
    I'm calling a web service and returning the following data in JSON format: ["OrderNumber":"12345","CustomerId":"555"] In my web service success method, I'm trying to parse both: $.ajax({ type: "POST", url: "MyService.asmx/ServiceName", data: "{}", contentType: "application/json; charset=utf-8", dataType: "json", success: function(msg) { var data = msg.d; var rtn = ""; $.each(data, function(list) { rtn = rtn + this.OrderNumber + ", " + this.CustomerId + "<br/>"; } rtn = rtn + "<br/>" + data; $("#test").html(rtn); } }); but I'm getting a bunch of "undefined, undefined" rows followed by the correct JSON string. Any idea why? I've tried using the eval() method but that didn't help as I got some error message talking about ']' being expected.

  • UILabel reset after Autorotate

    Hi, I have a UILabel in a view that is set by calling a method against my view controller. The app is a TABBar app and the VC is in the MORE section. When I rotate the phone the label disappears (don't mind that) when I rotate back the label is showing all .......... (the value it is set to in the XIB) I added a line to set the label in the shouldAutoRotateToOrientation method lblProductTxt.titleLabel.text = self.productText; when autorotating what viewcontroller methods are being called. ?? the shouldAutoRotateToOrientation method doesn't get called when the VC is in the More section but when I move it it does get called but has no affect on the labeltext

  • Where's all the XPCOM user documentation?

    - by Graham Paulson
    Google can't find much user documentation for XPCOM. Sure, it can find endless references to making new XPCOM components in C++, but that's utterly useless to anyone who needs to know how to use the existing components from JavaScript. This is a huge gap, occasionally touched on by trivial examples of creating an instance and calling a method. Has nobody with a more in-depth knowledge of the componentry written anything about its use? Using components with multiple interfaces? Implementing listeners for handling asynchronous behaviour? "Rapid Application Development with Mozilla" is no help (great breadth but little depth). Spotty references that exist to the defunct XULPlanet redirect to Mozilla Development Center, but that's pretty useless. Mozilla Development Center articles point back to XULPlanet, which is a joke. Is this the best an army of open source advocates can muster to promote the extension of The Beast?

  • Oracle analytic functions for "the atatrbute from the row with the max date"

    - by tpdi
    I'm refactoring a colleague's code, and I have several cases where he's using a cursor to get "the latest row that matches some predicate": His technique is to write the join as a cursor, order it by the date field descending, open the cursor, get the first row, and close the cursor. This requires calling a cursor for each row of the result set that drives this, which is costly for many rows. I'd prefer to be able to join, but what something cheaper than a correlated subquery: select a.id_shared_by_several_rows, a.foo from audit_trail a where a.entry_date = (select max(a.entry_date) from audit_trail b where b.id_shared_by_several_rows = a.id_shared_by_several_rows ); I'm guessing that since this is a common need, there's an Oracle analytic function that does this?

  • Symfony/Doctrine: Unserialize in action vs template

    - by Tom
    Hi, Can anyone tell me why calling "unserialize" works fine in an action but gives an offset error in a template? It's basically possible to unserialize a database text result into a variable in an action and pass it to template, in which case it displays fine: $this->clean = unserialize($this->raw); <?php echo $clean ?> But not if called directly in a template: <?php echo unserialize($raw) ?> Would be interested in knowing why this is so and whether there's some workaround. Thanks.

  • Problem with Marshalling char* in c#

    - by chrmue
    I have a problem calling this function from a c++ DLL in c# INT32 WINAPI PM_COM_GetText(INT32 TextId, char* pBuf, INT32 BufSize); It writes a Text in a buffer for a given text id. I try to call it with the following c# code, but I constantly get an access violation and don't undrestand why: public string GetText(Int32 TextId) { Int32 BufSize = 256; StringBuilder Str = new StringBuilder(BufSize); PM_COM_GetText(TextId, Str, BufSize); return Str.ToString(); } [DllImport("ComDll.dll", CharSet = CharSet.Ansi)] private static extern Int32 PM_COM_GetText(Int32 TextId, StringBuilder Str, Int32 BufSize); I don't see what's wrong, it looks to me like many other code snippets I found in the web. Any ideas? Thanks in advance!
