• Copying the bitmap contents of a UIView's context to that of another UIView

  - by Joonas Trussmann

  Basically what I want to do is copy the already rendered content (a PDF drawn into the UIView's graphics context using CGContextDrawPDFPage()) onto a similar UIView, without having to re render the PDF. The idea is, that I'd then be able to perform an animated transform on the UIView and later re render the PDF with more accuracy. For both UIViews I'm using a larger-than-screen CATiledLayer to make it easier to rerender the PDF once the user zooms in, if that makes any difference. Any tips? I'm kind of lost here.

• Visual Studio 2010 web.config transformations (TransformWebConfig target)

  - by Jeff D

  I am trying to write unit tests for my transformations, so I am running: msbuild migrated-project.csproj /p:Configuration=Release /T:TransformWebConfig. This works for a new project I create in VS2010, but doesn't in this project. I'm assuming it's because it was originally a 2008 project. I know this is supposed to run in a webplatformbuild whatever, but what I'm trying to do, is just run the transform, so I can grab the transformed web.config, and run some unit tests to make sure the right values exist. I don't see TransformWebConfig referenced as a target in either project, so I'm not sure what I'm looking for.

• Overlay WriteableBitmap with color

  - by rajenk

  I'm trying to overlay a WriteableBitmap with a certain color in Silverlight. I have a black and white base image, which I'm using to create smaller WriteableBitmap images for a new composite image and I want to overlay either the black or white part of the source image cut-out with a certain color before adding it to the composite image. What I'm doing now is: var cutOut = new WriteableBitmap(8, 14); /* cut out the image here */ cutOut.Render(sourceImage, transform); // sourceImage is the base image cutOutImage.Source = cutOut; // cutOutImage is an Image element in XAML compositeImage.Render(cutOutImage, transform2); // compositeImage is the final WriteableBitmap that is shown on screen I tried the methods on http://blogs.silverarcade.com/silverlight-games-101/15/silverlight-blitting-and-blending-with-silverlights-writeablebitmap/ and using the extension methods from hxxp://writeablebitmapex.codeplex.com/, but I cannot seem to get a color overlay on the cutOut image before rendering it to the compositeImage. Does anyone know of a good method to do this? Thanks in advance.

• Creating static NAT blocks outbound traffic Cisco ASA

  - by natediggs

  Hi Everyone, I have two web servers sitting behind a Cisco ASA 5505, which I don't have much experience with. I'm trying to create two static NATs. One static NAT that goes to xx.xx.xx.150 and another that goes to xx.xx.xx.151. I've created the static NAT for the .150 web server and it works FINE. Incoming and outgoing traffic work great. This is the staging web server. I now need to duplicate the setup for the production web server. So, I connect the webserver to the firewall, change the public IP address on one of the NICs reboot the server and I have outbound internet access. Then I run the command: static (inside,outside) xx.xx.xx.150 192.168.1.x which is successful. I then run the command: access-list acl-outside permit tcp any host xx.xx.xx.150 eq 80 Which is successful. I then try to browse the internet and I get nothing. I try to telnet in through port 80 and I get nothing (though I'm guessing because the response to the telnet request is being blocked). I've tried this with the production web server and then I tried it with another web server that is for internal testing and have the exact same problem. Both work fine until I run the static NAT rule and then no outbound internet access. I have a feeling that it's something simple that I'm missing, but my limited experience with this device is killing me. Below I've pasted the current configuration. I'm currently trying to get this to work on the .153 server which is the internal testing server. Once I can verify that works, I'll try it with production. : Saved : ASA Version 8.2(4) ! hostname QG domain-name XX.com enable password passwd names ! interface Ethernet0/0 switchport access vlan 2 !

• Horizontal UITableView

  - by imran

  I want implement a layout in my ipad application that has a uitable view that scrolls left and right rather then up and down : So rather than row 1 row 2 row 3 ( scrolling vertically ) It would be : row 1, row2, row 3 (scrolling horizontally ) I've seen that UItableView is designed to only do vertical scrolling so doing a transform does not give the desired effect. Is there a standard way to do this taking advantage of a datasource provider like uitableview provides? I basically want to do somthing similar to what the BBC News reader app ( http://itunes.apple.com/us/app/bbc-news/id364147881?mt=8 ) on the Ipad does with the list of stories to select from. Thanks

• Configuring a WCF Client to Use UserName Credentials On the Request and Check Certificate Credential

  - by AlEl

  I'm trying to use WCF to consume a web service provided by a third-party's Oracle Application Server. I pass a username and password in a UsernameToken as part of the request and as part of the response the web service returns a standard security tag in the header which includes a digest and signature. With my current setup, I successfully send a request to the server and the web service sends the expected response data back. However, when parsing the response WCF throws a MessageSecurityException, with an InnerException.Message of "Supporting token signatures not expected." My guess is that WCF wants me to configure it to handle the signature and verify it. I have a certificate from the third party that hosts the web service that I should be able to use to verify the signature, although I'm not sure if I'll need it. Here's a sample header from a response that makes WCF throw the exception: <?xml version="1.0" encoding="UTF-8"?> <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"> <soap:Header> <wsse:Security soap:mustUnderstand="1" xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" xmlns="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"> <dsig:Signature xmlns="http://www.w3.org/2000/09/xmldsig#" xmlns:dsig="http://www.w3.org/2000/09/xmldsig#"> <dsig:SignedInfo> <dsig:CanonicalizationMethod Algorithm="http://www.w3.org/2001/10/xml-exc-c14n#"/> <dsig:SignatureMethod Algorithm="http://www.w3.org/2000/09/xmldsig#rsa-sha1"/> <dsig:Reference URI="#_51IUwNWRVvPOcz12pZHLNQ22"> <dsig:Transforms> <dsig:Transform Algorithm="http://www.w3.org/2001/10/xml-exc-c14n#"/> </dsig:Transforms> <dsig:DigestMethod Algorithm="http://www.w3.org/2000/09/xmldsig#sha1"/> <dsig:DigestValue> [DigestValue here] </dsig:DigestValue> </dsig:Reference> <dsig:Reference URI="#_dI5j0EqxrVsj0e62J6vd6w22"> <dsig:Transforms> <dsig:Transform Algorithm="http://www.w3.org/2001/10/xml-exc-c14n#"/> </dsig:Transforms> <dsig:DigestMethod Algorithm="http://www.w3.org/2000/09/xmldsig#sha1"/> <dsig:DigestValue> [DigestValue here] </dsig:DigestValue> </dsig:Reference> </dsig:SignedInfo> <dsig:SignatureValue> [Signature Value Here] </dsig:SignatureValue> <dsig:KeyInfo> <wsse:SecurityTokenReference xmlns="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"> <wsse:Reference URI="#BST-9nKWbrE4LRv6maqstrGuUQ22" ValueType="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-x509-token-profile-1.0#X509v3"/> </wsse:SecurityTokenReference> </dsig:KeyInfo> </dsig:Signature> <wsse:BinarySecurityToken ValueType="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-x509-token-profile-1.0#X509v3" EncodingType="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#Base64Binary" wsu:Id="BST-9nKWbrE4LRv6maqstrGuUQ22" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd"> [Security Token Here] </wsse:BinarySecurityToken> <wsu:Timestamp wsu:Id="_dI5j0EqxrVsj0e62J6vd6w22" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" xmlns="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd"> <wsu:Created>2010-05-26T18:46:30Z</wsu:Created> </wsu:Timestamp> </wsse:Security> </soap:Header> <soap:Body wsu:Id="_51IUwNWRVvPOcz12pZHLNQ22" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd"> [Body content here] </soap:Body> </soap:Envelope> My binding configuration looks like: <basicHttpBinding> <binding name="myBinding" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" useDefaultWebProxy="true"> <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" /> <security mode="TransportWithMessageCredential"> <transport clientCredentialType="None" proxyCredentialType="None" realm="" /> <message clientCredentialType="UserName" algorithmSuite="Default" /> </security> </binding> </basicHttpBinding> I think that basically what I have to do is configure WCF to use UserName client credentials in the request and Certificate client credentials in the response. I don't know how to do this though. I'm new at WCF, so I'm sorry if this is a bit of a dumb question. I've been trying to Google solutions, but there seem to be so many different ways to configure WCF that I'm getting overwhelmed. Thanks in advance!

• How to fix flicker when using Webkit transforms & transitions

  - by gargantaun

  I have a very simple demo working that uses Webkit transforms and transitions for smooth horizontal scrolling between 'panels' (divs). The reason I want to go this route as opposed to a Javascript driven system is that it's for the iPad and Javascript performance is quite poor, but the css transforms and transitions are smooth as silk. Sadly though, I'm getting a lot of flicker on the iPad with my Demo. You can see the demo here You'll need safari or and iPad to see it in action. I've never seen this happening in any of the demos for transforms and transitions so I'm hopeful that this is fixable. Anyway here's the code that powers the thing.... The HTML looks like this. <html> <head> <title>Swipe Demo</title> <link href="test.css" rel="stylesheet" /> <link href="styles.css" rel="stylesheet" /> <script type="text/javascript" src="jquery.js"></script> <script type="text/javascript" src="functions.js"></script> <script type="text/javascript" src="swiping.js"></script> </head> <body> <div id="wrapper"> <div class='panel one'> <h1>This is panel 1</h1> </div> <div class='panel two'> <h1>This is panel 2</h1> </div> <div class='panel three'> <h1>This is panel 3</h1> </div> <div class='panel four'> <h1>This is panel 4</h1> </div> </div> </body> </html> The CSS looks like this body, html { padding: 0; margin: 0; background: #000; } #wrapper { width: 10000px; -webkit-transform: translateX(0px); } .panel { width: 1024px; height: 300px; background: #fff; display: block; float: left; position: relative; } and the javascript looks like this // Mouse / iPad Touch var touchSupport = (typeof Touch == "object"), touchstart = touchSupport ? 'touchstart' : 'mousedown', touchmove = touchSupport ? 'touchmove' : 'mousemove', touchend = touchSupport ? 'touchend' : 'mouseup'; $(document).ready(function(){ // set top and left to zero $("#wrapper").css("top", 0); $("#wrapper").css("left", 0); // get total number of panels var panelTotal; $(".panel").each(function(){ panelTotal += 1 }); // Touch Start // ------------------------------------------------------------------------------------------ var touchStartX; var touchStartY; var currentX; var currentY; var shouldMove = false; document.addEventListener(touchstart, swipeStart, false); function swipeStart(event){ touch = realEventType(event); touchStartX = touch.pageX; touchStartY = touch.pageY; var pos = $("#wrapper").position(); currentX = parseInt(pos.left); currentY = parseInt(pos.top); shouldMove = true; } // Touch Move // ------------------------------------------------------------------------------------------ var touchMoveX; var touchMoveY; var distanceX; var distanceY; document.addEventListener(touchmove, swipeMove, false); function swipeMove(event){ if(shouldMove){ touch = realEventType(event); event.preventDefault(); touchMoveX = touch.pageX; touchMoveY = touch.pageY; distanceX = touchMoveX - touchStartX; distanceY = touchMoveY - touchStartY; movePanels(distanceX); } } function movePanels(distance){ newX = currentX + (distance/4); $("#wrapper").css("left", newX); } // Touch End // ------------------------------------------------------------------------------------------ var cutOff = 100; var panelIndex = 0; document.addEventListener(touchend, swipeEnd, false); function swipeEnd(event){ touch = (touchSupport) ? event.changedTouches[0] : event; var touchEndX = touch.pageX; var touchEndY = touch.pageY; updatePanelIndex(distanceX); gotToPanel(); shouldMove = false; } // -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- function updatePanelIndex(distance){ if(distanceX > cutOff) panelIndex -= 1; if(distanceX < (cutOff * -1)){ panelIndex += 1; } if(panelIndex < 0){ panelIndex = 0; } if(panelIndex >= panelTotal) panelIndex = panelTotal -1; console.log(panelIndex); } // -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- function gotToPanel(){ var panelPos = getTotalWidthOfElement($(".panel")) * panelIndex * -1; $("#wrapper").css("-webkit-transition-property", "translateX"); $("#wrapper").css("-webkit-transition-duration", "1s"); $("#wrapper").css("-webkit-transform", "translateX("+panelPos+"px)"); } }); function realEventType(event){ e = (touchSupport) ? event.targetTouches[0] : event; return e; }

• ETL Tools and Build Tools

  - by Ngu Soon Hui

  I have familiarities with software automated build tools ( such as Automated Build Studio). Now I am looking at ETL tools. The one thing crosses my mind is that, I can do anything I can do in ETL tools by using a software build tool. ETL tools are tailored for data loading and manipulation for which a lot of scripts are needed in order to do the job. Software build tool, on the other hand, is versatile enough to do any jobs, including writing scripts to extract, transform and load any data from any format into any format. Am I right?

• Rotating a UIButton with a custom image (animation)

  - by Tiago

  Hi, I'm trying to rotate a button that I've connected to the controller from the Interface Builder. I've set it's image right from Interface Builder. I'm using this code on the method that runs when I click it: [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:2.0]; [UIView setAnimationRepeatCount:5]; updateButton.transform = CGAffineTransformMakeRotation( M_PI ); [UIView commitAnimations]; But this doesn't do anything. Can this be done, or should I create the button programmatically in order to get it to rotate?

• Any software transforming broken lines into curves?

  - by brilliant

  Hello, do you know of any software that would help me transform a broken line into a curved line? For example, I have an octagon or a heptagon and I want it to be transformed into something resembling a circle. if you know such software, please, let me know. Thank You! Update A: Here is an image from the tutorial given to me by Jamie Keeling (right now it's the first answer below). At least the picture there represents what I want. In that tutorial this process is called "flattening paths". I will try to put that image right here, but if it doesn't get displayed, you can find it here: http://msdn.microsoft.com/en-us/library/ms536364%28v=VS.85%29.aspx The red line in the picture is what I would want to submit, and the blue line is what I would want to get in the end:

• Extracting ""((Adj|Noun)+|((Adj|Noun)(Noun-Prep)?)(Adj|Noun))Noun"" from Text (Justeson & Katz, 1995)

  - by ssuhan

  I would like to query if it is possible to extract ((Adj|Noun)+|((Adj|Noun)(Noun-Prep)?)(Adj|Noun))Noun proposed by Justeson and Katz (1995) in R package openNLP? That is, I would like to use this linguistic filtering to extract candidate noun phrases. I cannot well understand its meaning. Could you do me a favor to explain it or transform such representation into R language. Many thanks. Maybe we can start the sample code from: library("openNLP") acq <- "This paper describes a novel optical thread plug gauge (OTPG) for internal thread inspection using machine vision. The OTPG is composed of a rigid industrial endoscope, a charge-coupled device camera, and a two degree-of-freedom motion control unit. A sequence of partial wall images of an internal thread are retrieved and reconstructed into a 2D unwrapped image. Then, a digital image processing and classification procedure is used to normalize, segment, and determine the quality of the internal thread." acqTag <- tagPOS(acq) acqTagSplit = strsplit(acqTag," ")

• VB FFT - stuck understanding relationship of results to frequency

  - by WaveyDavey

  Trying to understand an fft (Fast Fourier Transform) routine I'm using (stealing)(recycling) Input is an array of 512 data points which are a sample waveform. Test data is generated into this array. fft transforms this array into frequency domain. Trying to understand relationship between freq, period, sample rate and position in fft array. I'll illustrate with examples: ======================================== Sample rate is 1000 samples/s. Generate a set of samples at 10Hz. Input array has peak values at arr(28), arr(128), arr(228) ... period = 100 sample points peak value in fft array is at index 6 (excluding a huge value at 0) ======================================== Sample rate is 8000 samples/s Generate set of samples at 440Hz Input array peak values include arr(7), arr(25), arr(43), arr(61) ... period = 18 sample points peak value in fft array is at index 29 (excluding a huge value at 0) ======================================== How do I relate the index of the peak in the fft array to frequency ?

• What is the simplest way to implement multithredding in c# to existing code

  - by Kaeso

  I have already implemented a functionnal application that parses 26 pages of html all at once to produce an xml file with data contained on the web pages. I would need to implement a thread so that this method can work in the background without causing my app to seems unresponsive. Secondly, I have another function that is decoupled from the first one which compares two xml files to produce a third one and then transform this third xml file to produce an html page using XSLT. This would have to be on a thread, where I can click Cancel to stop the thread whithout crashing the app. What is the easiest best way to do this using WPF forms in VS 2010 ? Note: I cannot use the BackgroundWorker component as it is grayed out in the toolbox.

• MathML or OMML to PNG w/ .NET?

  - by charliedigital

  Are there any libraries which take MathML (or, even more preferably, OMML) and outputs a .PNG file? I am putting together an export process for .docx files and, as a part of this process, I'd like to extract equations and render them as .PNG files. Word 2007 does this natively when you save a document for the web, but so far, I have not been able to find a way to do this programmatically (if anyone has an answer for that, it would be even better). So the next best thing is to take the OMML and use the Microsoft provided XSL stylesheets and transform them to MathML. Unfortunately, I haven't been able to find any (working) rendering libraries for either MathML or OMML. If there aren't any pure .NET libraries for this, I'll settle for just about anything that I can call from a commandline to output a .PNG from either MathML or OMML.

• Rotating a full 360 degrees in WPF 3D

  - by sklitzz

  Hi, I have a ModelVisual3D of a cube and I want to animate it to rotate around its axis for 360 degrees. I make a RoationTransform3D which I tell to rotate 360 but it doesn't rotate at all, also if you say 270 degrees it rotates only 90 degrees but in the opposite direction. I guess he computer calculates the "shortest path" of the rotation. The best solution I have come up with is to make one animation turn 180 and after it finishes call another 180 to complete the full rotation. Is there a way to do it in one animation? RotateTransform3D rotateTransform = new RotateTransform3D(); myCube.Model.Transform = rotateTransform; AxisAngleRotation3D rotateAxis = new AxisAngleRotation3D(new Vector3D(0, 1, 0), 180/*or 360*/); Rotation3DAnimation rotateAnimation = new Rotation3DAnimation(rotateAxis, TimeSpan.FromSeconds(2)); rotateTransform.BeginAnimation(RotateTransform3D.RotationProperty, rotateAnimation);

• Objective-C RGB to HSB

  - by Johannes Jensen

  Let's say I've got the colour FF0000, which is red. Finding a darker colour is easy, I just type maybe CC instead of the FF, but let's say I've got the colour AE83FC, which is a complicated colour, how the heck would I find a lighter or darker version of it automatically? I figured the easy way to do this is to convert my RGB to HSB [Hue, Saturation, Brightness] How would I do that in Objective-C? Let's say I've got a RGB which is: 1.0, 0.0, 0.0. That's red. CGFloat r = 1.0; CGFloat g = 0.0; CGfloat b = 0.0; How would I convert that to HSB and then transform the colors and make it go back to RGB to I can use CGContextRGBSetFillColor? Are there any HSB functions? Please help. :)

• Resizing JPEG image during decoding

  - by Thomas

  I'm working on a program that creates thumbnails of JPEG images on the fly. Now I was thinking: since a JPEG image is built from 8x8-pixel blocks (Wikipedia has a great explanation), would it be possible to skip part of the decoding? Let's say that my thumbnails are at least 8 times smaller than the original image. We could then map each 8x8 block in the input file to 1 pixel in the decoding output, by including only the constant term of the discrete cosine transform. Most of the image data can be discarded right away, and need not be processed. Moreover, the memory usage is reduced by a factor of 64. I don't want to implement this from scratch; that'll easily take a week. Is there any code out there that can do this? If not, is this because this approach isn't worthwhile, or simply because nobody has thought of it yet?

• Changing One Tag Name in an XML File Using XSLT

  - by AlbertoPL

  Is it possible for me to have a conditional in XSLT such that I find and replace only the FIRST tag of a particular tag name? For example, I have an XML file with many tags. I would like to replace the first of these tags with . The rest should be left alone. How would I do this in my transform? What I currently have is this: <xsl:template match="title"> <PageTitle> <xsl:apply-templates /> </PageTitle> </xsl:template> which finds all tags and replaces them with PageTitle. Any help would be greatly appreciated!

• What is an efficient way to write password cracking algorithm (python)

  - by Luminance

  This problem might be relatively simple, but I'm given two text files. One text file contains all encrypted passwords encrypted via crypt.crypt in python. The other list contains over 400k+ normal dictionary words. The assignment is that given 3 different functions which transform strings from their normal case to all different permutations of capitalizations, transforms a letter to a number (if it looks alike, e.g. G - 6, B - 8), and reverses a string. The thing is that given the 10 - 20 encrypted passwords in the password file, what is the most efficient way to get the fastest running solution in python to run those functions on dictionary word in the words file? It is given that all those words, when transformed in whatever way, will encrypt to a password in the password file. Here is the function which checks if a given string, when encrypted, is the same as the encrypted password passed in: def check_pass(plaintext,encrypted): crypted_pass = crypt.crypt(plaintext,encrypted) if crypted_pass == encrypted: return True else: return False Thanks in advance.

• Can you use the Phoenix compiler as a more powerful NGEN?

  - by TraumaPony

  In case you don't know of Phoenix, it's a compiler framework from Microsoft that's apparantly going to be the foundation of all their new compilers. It can read in code from CIL, x86, x64, and IA64; and emit code in x86, x64, IA64, or CIL. Can I use it to transform a pure .Net app into a pure native app? By which I mean, it will not have to load any .Net .dll (not even mscoree), and will have the same semantics? This is excluding Reflection, of course.

• JAXB: @XmlTransient on third-party or external super class

  - by Phil

  Hi, I need some help regarding the following issue with JAXB 2.1. Sample: I've created a SpecialPerson class that extends a abstract class Person. Now I want to transform my object structure into a XML schema using JAXB. Thereby I don't want the Person XML type to appear in my XML schema to keep the schema simple. Instead I want the fields of the Person class to appear in the SpecialPerson XML type. Normally I would add the annotation @XmlTransient on class level into the Person code. The problem is that Person is a third-party class and I have no possibility to add @XmlTransient here. How can I tell JAXB that it should ignore the Person class without annotating the class. Is it possible to configure this externally somehow? Have you had the same problem before? Any ideas what the best solution for this problem would be?

• How To find the location of any treeviewitem in silverlight

  - by user312772

  Hi I am new in silverlight 3. I want to find the location of any treeview Item . Although I applied this code GeneralTransform gt = ProjectTree.TransformToVisual(Application.Current.RootVisual as UIElement); Point offset = gt.Transform(new Point(0, 0)); double controlTop = offset.Y; double controlLeft = offset.X; Here Project tree is the root element of the treeview. This code is working But when I applied this for any child TreeViewelement of Treeview then an exception occurs "Value does not fall within the expected range." How to find the location of this child treeview element object

• Repairing malformatted html attributes using c#

  - by jhoefnagels

  I have a web application with an upload functionality for HTML files generated by chess software to be able to include a javascript player that reproduces a chess game. I do not like to load the uploaded files in a frame so I reconstruct the HTML and javascript generated by the software by parsing the dynamic parts of the file. The problem with the HTML is that all attributes values are surrounded with an apostrophe instead of a quotation mark. I am looking for a way to fix this using a library or a regex replace using c#. The html looks like this: <DIV class='pgb'><TABLE class='pgbb' CELLSPACING='0' CELLPADDING='0'><TR><TD> and I would transform it into: <DIV class="pgb"><TABLE class="pgbb" CELLSPACING="0" CELLPADDING="0"><TR><TD>
