  • How to get attribute value using SelectSingleNode in C#?

    - by Nano HE
    Hello. I am parsing a xml document, I need find out the gid (an attribute) value (3810). Based on SelectSingleNode(). I found it is not easy to find the attribute name and it's value. Can I use this method or I must switch to other way. Attached my code. How can I use book obj to get the attribute value3810 for gid. Thank you. My test.xml file as below <?xml version="1.0"?> <root> <VersionInfo date="2007-11-28" version="1.0.0.2"/> <Attributes> <AttrDir name="EFEM" DirID="1"> <AttrDir name="Aligner" DirID="2"> <AttrDir name="SequenceID" DirID="3"> <AttrObj text="Slot01" gid="3810" unit="" scale="1"/> <AttrObjCount value="1"/> </AttrDir> </AttrDir> </AttrDir> </Attributes> </root> I wrote the test.cs as below public class Sample { public static void Main() { XmlDocument doc = new XmlDocument(); doc.Load("test.xml"); XmlNode book; XmlNode root = doc.DocumentElement; book = root.SelectSingleNode("Attributes[AttrDir[@name='EFEM']/AttrDir[@name='Aligner']/AttrDir[@name='SequenceID']/AttrObj[@text='Slot01']]"); Console.WriteLine("Display the modified XML document...."); doc.Save(Console.Out); } }

  • How to pass XML from C# to a stored procedure in SQL Server 2008?

    - by Geetha
    I want to pass xml document to sql server stored procedure such as this: CREATE PROCEDURE BookDetails_Insert (@xml xml) I want compare some field data with other table data and if it is matching that records has to inserted in to the table. Requirements: How do I pass XML to the stored procedure? I tried this, but it doesn’t work:[Working] command.Parameters.Add( new SqlParameter("@xml", SqlDbType.Xml) { Value = new SqlXml(new XmlTextReader(xmlToSave.InnerXml, XmlNodeType.Document, null)) }); How do I access the XML data within the stored procedure?

  • Facebook / Offline Permission - Trying to perform an action on a set of offline users.

    - by blueigloo
    Hi there, We're building an app which in part of its functionality tries to capture the number of likes associated to a particular video owned by a user. Users of the app are asked for extended off-line access and we capture the key for each user: The format is like this: 2.hg2QQuYeftuHx1R84J1oGg__.XXXX.1272394800-nnnnnn Each user has their offline / infinite key stored in a table in a DB. The object_id which we're interested in is also stored in the DB. At a later stage (offline) we try to run a batch job which reads the number of likes for each user's video. (See attached code) For some reason however, after the first iteration of the loop - which yields the likes correctly, we get a failure with the oh so familiar message: "Session key is invalid or no longer valid" Any insight would be most appreciated. Thanks, B List<DVideo> videoList = db.SelectVideos(); foreach (DVideo video in videoList) { long userId = 0; ConnectSession fbSession = new ConnectSession(APPLICATION_KEY, SECRET_KEY); //session key is attached to the video object for now. fbSession.SessionKey = video.UserSessionKey; fbSession.SessionExpires = false; string fbuid =video.FBUID; long.TryParse(fbuid, out userId); if (userId > 0) { fbSession.UserId = userId; fbSession.Login(); Api fbApi = new Facebook.Rest.Api(fbSession); string xmlQueryResult = fbApi.Fql.Query("SELECT user_id FROM like WHERE object_id = " + video.FBVID); XmlDocument xmlDoc = new XmlDocument(); xmlDoc.Load(new StringReader(xmlQueryResult)); int likesCount = xmlDoc.GetElementsByTagName("user_id").Count; //Write entry in VideoWallLikes if (likesCount > 0) { db.CountWallLikes(video.ID, likesCount); } fbSession.Logout(); } fbSession = null; }

  • Deleting items from datagrid (xml)

    - by Tonz
    Hello, I have a datagrid buttoncolumn which acts as delete buttons for my xml nodes. The elements are simply displayed in a boundcolumn, so there names get displayed. Each item generated gets a unique id (each time one is made id+++). My question his how can i remove a item (the entire element node with that certain id) when i click on one of the buttons in the bound column? <root> <element id="0"> <name>One</name> </element> <element id="1"> <name>Two</name> </element> </root> protected void dg_DeleteCommand(object sender, DataGridCommandEventArgs e) { XmlFunctions.Remove(index); }/*dg_DeleteCommand*/ (function on other class, where all my xml methods are written) public static void Remove(string index) { XmlDocument XMLDoc = new XmlDocument(); XMLDoc.Load(XMLFile); XPathNavigator nav = XMLDoc.CreateNavigator(); var node = nav.SelectSingleNode("/test/one[@id='" +???+ "']"); node.DeleteSelf(); XMLDoc.Save(XMLFile); } Edit: added datagrid <asp:View ID="viewDelete" runat="server"> <asp:DataGrid ID="dgDelete runat="server" AutoGenerateColumns="False" OnDeleteCommand="dg_DeleteCommand"> <Columns> <asp:BoundColumn DataField="name" HeaderText="names" /> <asp:ButtonColumn ButtonType="PushButton" Text="Delete" CommandName="Delete" ></asp:ButtonColumn> </Columns> </asp:DataGrid> </asp:View>

  • Working with Tile Notifications in Windows 8 Store Apps – Part I

    - by dwahlin
    One of the features that really makes Windows 8 apps stand out from others is the tile functionality on the start screen. While icons allow a user to start an application, tiles provide a more engaging way to engage the user and draw them into an application. Examples of “live” tiles on part of my current start screen are shown next: I’ll admit that if you get enough of these tiles going the start screen can actually be a bit distracting. Fortunately, a user can easily disable a live tile by right-clicking on it or pressing and holding a tile on a touch device and then selecting Turn live tile off from the AppBar: The can also make a wide tile smaller (into a square tile) or make a square tile bigger assuming the application supports both squares and rectangles. In this post I’ll walk through how to add tile notification functionality into an application. Both XAML/C# and HTML/JavaScript apps support live tiles and I’ll show the code for both options.   Understanding Tile Templates The first thing you need to know if you want to add custom tile functionality (live tiles) into your application is that there is a collection of tile templates available out-of-the-box. Each tile template has XML associated with it that you need to load, update with your custom data, and then feed into a tile update manager. By doing that you can control what shows in your app’s tile on the Windows 8 start screen. So how do you learn more about the different tile templates and their respective XML? Fortunately, Microsoft has a nice documentation page in the Windows 8 Store SDK. Visit http://msdn.microsoft.com/en-us/library/windows/apps/hh761491.aspx to see a complete list of square and wide/rectangular tile templates that you can use. Looking through the templates you’ll It has the following XML template associated with it:  <tile> <visual> <binding template="TileSquareBlock"> <text id="1">Text Field 1</text> <text id="2">Text Field 2</text> </binding> </visual> </tile> An example of a wide/rectangular tile template is shown next:    <tile> <visual> <binding template="TileWideImageAndText01"> <image id="1" src="image1.png" alt="alt text"/> <text id="1">Text Field 1</text> </binding> </visual> </tile>   To use these tile templates (or others you find interesting), update their content, and get them to show for your app’s tile on the Windows 8 start screen you’ll need to perform the following steps: Define the tile template to use in your app Load the tile template’s XML into memory Modify the children of the <binding> tag Feed the modified tile XML into a new TileNotification instance Feed the TileNotification instance into the Update() method of the TileUpdateManager In the remainder of the post I’ll walk through each of the steps listed above to provide wide and square tile notifications for an application. The wide tile that’s shown will show an image and text while the square tile will only show text. If you’re going to provide custom tile notifications it’s recommended that you provide wide and square tiles since users can switch between the two of them directly on the start screen. Note: When working with tile notifications it’s possible to manipulate and update a tile’s XML template without having to know XML parsing techniques. This can be accomplished using some C# notification extension classes that are available. In this post I’m going to focus on working with tile notifications using an XML parser so that the focus is on the steps required to add notifications to the Windows 8 start screen rather than on external extension classes. You can access the extension classes in the Windows 8 samples gallery if you’re interested.   Steps to Create Custom App Tile Notifications   Step 1: Define the tile template to use in your app Although you can cut-and-paste a tile template’s XML directly into your C# or HTML/JavaScript Windows store app and then parse it using an XML parser, it’s easier to use the built-in TileTemplateType enumeration from the Windows.UI.Notifications namespace. It provides direct access to the XML for the various templates so once you locate a template you like in the documentation (mentioned above), simplify reference it:HTML/JavaScript var notifications = Windows.UI.Notifications; var template = notifications.TileTemplateType.tileWideImageAndText01; .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; }   XAML/C# var template = TileTemplateType.TileWideImageAndText01;   Step 2: Load the tile template’s XML into memory Once the target template’s XML is identified, load it into memory using the TileUpdateManager’s GetTemplateContent() method. This method parses the template XML and returns an XmlDocument object:   HTML/JavaScript   var tileXml = notifications.TileUpdateManager.getTemplateContent(template); .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; }   XAML/C#  var tileXml = TileUpdateManager.GetTemplateContent(template);   Step 3: Modify the children of the <binding> tag Once the XML for a given template is loaded into memory you need to locate the appropriate <image> and/or <text> elements in the XML and update them with your app data. This can be done using standard XML DOM manipulation techniques. The example code below locates the image folder and loads the path to an image file located in the project into it’s inner text. The code also creates a square tile that consists of text, updates it’s <text> element, and then imports and appends it into the wide tile’s XML.   HTML/JavaScript var image = tileXml.selectSingleNode('//image[@id="1"]'); image.setAttribute('src', 'ms-appx:///images/' + imageFile); image.setAttribute('alt', 'Live Tile'); var squareTemplate = notifications.TileTemplateType.tileSquareText04; var squareTileXml = notifications.TileUpdateManager.getTemplateContent(squareTemplate); var squareTileTextAttributes = squareTileXml.selectSingleNode('//text[@id="1"]'); squareTileTextAttributes.appendChild(squareTileXml.createTextNode(content)); var node = tileXml.importNode(squareTileXml.selectSingleNode('//binding'), true); tileXml.selectSingleNode('//visual').appendChild(node); .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; }   XAML/C#var tileXml = TileUpdateManager.GetTemplateContent(template); var text = tileXml.SelectSingleNode("//text[@id='1']"); text.AppendChild(tileXml.CreateTextNode(content)); var image = (XmlElement)tileXml.SelectSingleNode("//image[@id='1']"); image.SetAttribute("src", "ms-appx:///Assets/" + imageFile); image.SetAttribute("alt", "Live Tile"); Debug.WriteLine(image.GetXml()); var squareTemplate = TileTemplateType.TileSquareText04; var squareTileXml = TileUpdateManager.GetTemplateContent(squareTemplate); var squareTileTextAttributes = squareTileXml.SelectSingleNode("//text[@id='1']"); squareTileTextAttributes.AppendChild(squareTileXml.CreateTextNode(content)); var node = tileXml.ImportNode(squareTileXml.SelectSingleNode("//binding"), true); tileXml.SelectSingleNode("//visual").AppendChild(node);  Step 4: Feed the modified tile XML into a new TileNotification instance Now that the XML data has been updated with the desired text and images, it’s time to load the XmlDocument object into a new TileNotification instance:   HTML/JavaScript var tileNotification = new notifications.TileNotification(tileXml); .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; }   XAML/C#var tileNotification = new TileNotification(tileXml);  Step 5: Feed the TileNotification instance into the Update() method of the TileUpdateManager Once the TileNotification instance has been created and the XmlDocument has been passed to its constructor, it needs to be passed to the Update() method of a TileUpdator in order to be shown on the Windows 8 start screen:   HTML/JavaScript notifications.TileUpdateManager.createTileUpdaterForApplication().update(tileNotification); .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; }   XAML/C#TileUpdateManager.CreateTileUpdaterForApplication().Update(tileNotification);    Once the tile notification is updated it’ll show up on the start screen. An example of the wide and square tiles created with the included demo code are shown next:     Download the HTML/JavaScript and XAML/C# sample application here. In the next post in this series I’ll walk through how to queue multiple tiles and clear a queue.

  • Get your content off Blogger.com

    - by Daniel Moth
    Due to blogger.com deprecating FTP users I've decided to move my blog. When I think of the content of a blog, 4 items come to mind: blog posts, comments, binary files that the blog posts linked to (e.g. images, ZIP files) and the CSS+structure of the blog. 1. Binaries The binary files you used in your blog posts are sitting on your own web space, so really blogger.com is not involved with that. Nothing for you to do at this stage, I'll come back to these in another post. 2. CSS and structure In the best case this exists as a separate CSS file on your web space (so no action for now) or in a worst case, like me, your CSS is embedded with the HTML. In the latter case, simply navigate from you dashboard to "Template" then "Edit HTML" and copy paste the contents of the box. Save that locally in a txt file and we'll come back to that in another post. 3. Blog posts and Comments The blog posts and comments exist in all the HTML files on your own web space. Parsing HTML files to extract that can be painful, so it is easier to download the XML files from blogger's servers that contain all your blog posts and comments. 3.1 Single XML file, but incomplete The obvious thing to do is go into your dashboard "Settings" and under the "Basic" tab look at the top next to "Blog Tools". There is a link there to "Export blog" which downloads an XML file with both comments and posts. The problem with that is that it only contains 200 comments - if you have more than that, you will lose the surplus. Also, this XML file has a lot of noise, compared to the better solution described next. (note that a tool I will refer to in a future post deals with either kind of XML file) 3.2 Multiple XML files First you need to find your blog ID. In case you don't know what that is, navigate to the "Template" as described in section 2 above. You will find references to the blog id in the HTML there, but you can also see it as part of the URL in your browser: blogger.com/template-edit.g?blogID=YOUR_NUMERIC_ID. Mine is 7 digits. You can now navigate to these URLs to download the XML for your posts and comments respectively: blogger.com/feeds/YOUR_NUMERIC_ID/posts/default?max-results=500&start-index=1 blogger.com/feeds/YOUR_NUMERIC_ID/comments/default?max-results=200&start-index=1 Note that you can only get 500 posts at a time and only 200 comments at a time. To get more than that you have to change the URL and download the next batch. To get you started, to get the XML for the next 500 posts and next 200 comments respectively you’d have to use these URLs: blogger.com/feeds/YOUR_NUMERIC_ID/posts/default?max-results=500&start-index=501 blogger.com/feeds/YOUR_NUMERIC_ID/comments/default?max-results=200&start-index=201 ...and so on and so forth. Keep all the XML files in the same folder on your local machine (with nothing else in there). 4. Validating the XML aka editing older blog posts The XML files you just downloaded really contain HTML fragments inside for all your blog posts. If you are like me, your blog posts did not conform to XHTML so passing them to an XML parser (which is what we will want to do) will result in the XML parser choking. So the next step is to fix that. This can be no work at all for you, or a huge time sink or just a couple hours of pain (which was my case). The process I followed was to attempt to load the XML files using XmlDocument.Load and wait for the exception to be thrown from my code. The exception would point to the exact offending line and column which would help me fix the issue. Rather than fix it in the XML itself, I would go back and edit the offending blog post and fix it there - recommended! Then I'd repeat the cycle until the XML could be loaded in the XmlDocument. To give you an idea, some of the issues I encountered are: extra or missing quotes in img and href elements, direct usage of chevrons instead of encoding them as &lt;, missing closing tags, mismatched nested pairs of elements and capitalization of html elements. For a full list of things that may go wrong see this. 5. Opportunity for other changes I also found a few posts that did not have a category assigned so I fixed those too. I took the further opportunity to create new categories and tag some of my blog posts with that. Note that I did not remove/change categories of existing posts, but only added.   In an another post we'll see how to use the XML files you stored in the local folder… Comments about this post welcome at the original blog.

  • How can I test a parser for a bespoke XML schema?

    - by Greg B
    I'm parsing a bespoke XML format into an object graph using .NET 4.0. My parser is using the System.XML namespace internally, I'm then interrogating the relevant properties of XmlNodes to create my object graph. I've got a first cut of the parser working on a basic input file and I want to put some unit tests around this before I progress on to more complex input files. Is there a pattern for how to test a parser such as this? When I started looking at this, my first move was to new up and XmlDocument, XmlNamespaceManager and create an XmlElement. But it occurs to me that this is quite lengthy and prone to human error. My parser is quite recursive as you can imagine and this might lead to testing the full system rather than the individual units (methods) of the system. So a second question might be What refactoring might make a recursive parser more testable?

  • How to get attribute value using SelectSingleNode?

    - by Nano HE
    I am parsing a xml document, I need find out the gid (an attribute) value (3810). Based on SelectSingleNode(). I found it is not easy to find the attribute name and it's value. Can I use this method or I must switch to other way. Attached my code. How can I use book obj to get the attribute value3810 for gid. Thank you. My test.xml file as below <?xml version="1.0" ?> <root> <VersionInfo date="2007-11-28" version="1.0.0.2" /> <Attributes> <AttrDir name="EFEM" DirID="1"> <AttrDir name="Aligner" DirID="2"> <AttrDir name="SequenceID" DirID="3"> <AttrObj text="Slot01" gid="3810" unit="" scale="1" /> <AttrObjCount value="1" /> </AttrDir> </AttrDir> </AttrDir> </Attributes> </root> I wrote the test.cs as below public class Sample { public static void Main() { XmlDocument doc = new XmlDocument(); doc.Load("test.xml"); XmlNode book; XmlNode root = doc.DocumentElement; book = root.SelectSingleNode("Attributes[AttrDir[@name='EFEM']/AttrDir[@name='Aligner']/AttrDir[@name='SequenceID']/AttrObj[@text='Slot01']]"); Console.WriteLine("Display the modified XML document...."); doc.Save(Console.Out); } } [Update 06/10/2010] The xml file is a complex file. Included thousands of gids. But for each of Xpath, the gid is unique. I load the xml file to a TreeView control. this.treeView1.AfterSelect += new System.Windows.Forms.TreeViewEventHandler(this.treeView1_AfterSelect);. When treeView1_AfterSelect event occurred, the e.Node.FullPath will return as a String Value. I parse the string Value e.Node.FullPath. Then I got the member of XPath Above. Then I tried to find which gid item was selected. I need find the gid value as a return value indeed.

  • C# XPath Not Finding Anything

    - by ehdv
    I'm trying to use XPath to select the items which have a facet with Location values, but currently my attempts even to just select all items fail: The system happily reports that it found 0 items, then returns (instead the nodes should be processed by a foreach loop). I'd appreciate help either making my original query or just getting XPath to work at all. XML <?xml version="1.0" encoding="UTF-8" ?> <Collection Name="My Collection" SchemaVersion="1.0" xmlns="http://schemas.microsoft.com/collection/metadata/2009" xmlns:p="http://schemas.microsoft.com/livelabs/pivot/collection/2009" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <FacetCategories> <FacetCategory Name="Current Address" Type="Location"/> <FacetCategory Name="Previous Addresses" Type="Location" /> </FacetCategories> <Items> <Item Id="1" Name="John Doe"> <Facets> <Facet Name="Current Address"> <Location Value="101 America Rd, A Dorm Rm 000, Chapel Hill, NC 27514" /> </Facet> <Facet Name="Previous Addresses"> <Location Value="123 Anywhere Ln, Darien, CT 06820" /> <Location Value="000 Foobar Rd, Cary, NC 27519" /> </Facet> </Facets> </Item> </Items> </Collection> C# public void countItems(string fileName) { XmlDocument document = new XmlDocument(); document.Load(fileName); XmlNode root = document.DocumentElement; XmlNodeList xnl = root.SelectNodes("//Item"); Console.WriteLine(String.Format("Found {0} items" , xnl.Count)); } There's more to the method than this, but since this is all that gets run I'm assuming the problem lies here. Calling root.ChildNodes accurately returns FacetCategories and Items, so I am completely at a loss. Thanks for your help!

    Hi All, I'm researching Selenium and have a seminar for my group... I meet many troubles with this I use C# language and write a demo SeleniumExample.dll Then i start selenium RC and NUnit and run it with nUnit to see the test report. I read testdata from xml. Here's the SeleniumExample.dll: using System; using System.Xml; using System.Text; using System.Text.RegularExpressions; using System.Threading; using NUnit.Framework; using Selenium; namespace SeleniumExample { public class Success_Login { //User defined private string strURL = "http://newtours.demoaut.com/ mercurywelcome.php"; private string[] strBrowser = new string[3] { "*iehta", "*firefox", "*safari" }; // System defined private ISelenium selenium; private StringBuilder verificationErrors ; [SetUp] public void SetupTest() { selenium = new DefaultSelenium("localhost", 4444, this.strBrowser[0], this.strURL); selenium.Start(); verificationErrors = new StringBuilder(); } [TearDown] public void TeardownTest() { try { selenium.Stop(); } catch (Exception) { // Ignore errors if unable to close the browser } Assert.AreEqual("", verificationErrors.ToString()); } [Test] public void Success_LoginTest() { try { XmlDocument doc = new XmlDocument(); XmlNode docNode; doc.Load("XMLFile1.xml"); docNode = doc["TestCase"]; foreach (XmlNode node in docNode) { selenium.Open("/"); selenium.Type("userName", node["username"].InnerText); selenium.Type("password", node["password"].InnerText); selenium.Click("login"); selenium.WaitForPageToLoad("30000"); Assert.AreEqual("Find a Flight: Mercury Tours:", selenium.GetTitle()); } } catch (AssertionException e) { verificationErrors.Append(e.Message); } } } } Now I wan to have a demo that using Selenium Grid (SG) but i dont know how to do. I read document and understand the way SG works. I install SG and install Ant1.8. The tests will communicate with Selenium Hub. Actually, I just understand the theory i dont know how to make the tests communicate with Selenium Hub and how to make Selenium Hub control Selenium RC. I am a new for Selenium. If anyone know this, please help me. I appreciate it so much. THANKS, Hoang

  • How to make the selected testcript is run in selenium grid

    - by Yui
    Hi, I can launch some remote control by using: ant launch-remote-control but I dont know how my script connect to hub? I set up ant, selenium-grid on the same computer. I have an grid.dll which is written by C# and run through NUnit. The test data is read from xml file (ValidData.xml) The example code is below : using System.Collections.Generic; using System.Linq; using System.Text; using System; using System.Xml; using System.Text.RegularExpressions; using System.Threading; using NUnit.Framework; using Selenium; namespace Grid { public class Class1 { //User defined private string strURL = "http://gmail.com/"; private string[] strBrowser = new string[3] { "*iehta", "*firefox", "*safari" }; string hubAddress = "192.168.20.131"; // IP of my computer // System defined private ISelenium selenium; private StringBuilder verificationErrors; [SetUp] public void SetupTest() { selenium = new DefaultSelenium(hubAddress, 4444, this.strBrowser[1], this.strURL);// do i need to identify browser when I defined it when launching a remote control selenium.Start(); verificationErrors = new StringBuilder(); } [TearDown] public void TeardownTest() { try { selenium.Stop(); } catch (Exception) { // Ignore errors if unable to close the browser } Assert.AreEqual("", verificationErrors.ToString()); } private string[] name; [Test] public void LoginPassedTest() { try { XmlDocument doc = new XmlDocument(); XmlNode docNode; doc.Load("ValidData.xml"); docNode = doc["TestCase"]; foreach (XmlNode node in docNode) { selenium.Open("/"); selenium.WaitForPageToLoad("50000"); selenium.Type("Email", node["username"].InnerText); selenium.Type("Passwd", node["password"].InnerText); selenium.Click("signIn"); selenium.WaitForPageToLoad("100000"); name = (selenium.GetText("//div[@id='guser']/nobr/b").Split('@')); try { Assert.AreEqual(node["username"].InnerText, name[0]); Assert.AreEqual("Sign out", selenium.GetText(":r6")); } catch (AssertionException e) { verificationErrors.Append(e.Message); } selenium.Click(":r6"); } } catch (AssertionException e) { verificationErrors.Append(e.Message); } } } } Step I run this script: 1.I build that script into DLL 2.I start hub by using command "ant lauch-hub" 3.I start 2 remote controls by using command : ant -Dport=5566 -Denvironment="*chrome" launch-remote-control ant -Dport=5577 -Denvironment="*iexplore" launch-remote-control 4.Then I open Nunit and load DLL (code above) and run 5.The NUNit doesnot respond anything. I think there are some missing things but I dont know. How can the test script (DLL) know which is sequence of remote control is selected to run the test???? Please help me!! Thank you so much Yui.

  • trouble resolving location in <xs:import > element in C#

    - by BobC
    I'm using an XML schema document to validate incoming data documents, however the schema appears be failing during compilation at run time because it refers to a complex type which part of an external schema. The external schema is specified in a element at the top of the document. I had thought it might be an access problem, so I moved a copy of the external document to a localhost folder. I get the same error, so now I'm wondering if there might be some sort of issue with the use of the element. The schema document fragment looks like this: <xs:schema targetNamespace="http://www.smpte-ra.org/schemas/429-7/2006/CPL" xmlns:cpl="http://www.smpte-ra.org/schemas/429-7/2006/CPL" xmlns:ds="http://www.w3.org/2000/09/xmldsig#" xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" attributeFormDefault="unqualified"> ... <xs:import namespace="http://www.w3.org/2000/09/xmldsig#" schemaLocation="http://localhost/TMSWebServices/XMLSchema/xmldsig-core-schema.xsd"/> ... <xs:element name="Signer" type="ds:KeyInfoType" minOccurs="0"/> ... </xs:schema> The code I'm trying to run this with is real simple (got it from http://dotnetslackers.com/Community/blogs/haissam/archive/2008/11/06/validate-xml-against-xsd-xml-schema-using-c.aspx) string XSDFILEPATH = @"http://localhost/TMSWebServices/XMLSchema/CPL.xsd"; string XMLFILEPATH = @"C:\foo\bar\files\TestCPLs\CPL_930f5e92-be03-440c-a2ff-a13f3f16e1d6.xml"; System.Xml.XmlReaderSettings settings = new System.Xml.XmlReaderSettings(); settings.Schemas.Add(null, XSDFILEPATH); settings.ValidationType = System.Xml.ValidationType.Schema; System.Xml.XmlDocument document = new System.Xml.XmlDocument(); document.Load(XMLFILEPATH); System.Xml.XmlReader rdr = System.Xml.XmlReader.Create(new StringReader(document.InnerXml), settings); while (rdr.Read()) { } Everything goes well until the line that instantiates the XMLReader object just before the while loop. Then it fails with a type not declared error. The type that it's trying to find, KeyInfoType, is defined in one of the the documents in the import element. I've made sure the namespaces line up. I wondered if the # signs in the namespace definitions were causing a problem, but removing them had no effect, it just changed what the error looked like (i.e. "Type 'http://www.w3.org/2000/09/xmldsig:KeyInfoType' is not declared." versus "Type 'http://www.w3.org/2000/09/xmldsig#:KeyInfoType' is not declared.") My suspicion is that there's something about the processing of the element that I'm missing. Any suggestions are very welcome. Thanks!

  • Securing a license key with RSA key.

    - by Jesse Knott
    Hello, it's late, I'm tired, and probably being quite dense.... I have written an application that I need to secure so it will only run on machines that I generate a key for. What I am doing for now is getting the BIOS serial number and generating a hash from that, I then am encrypting it using a XML RSA private key. I then sign the XML to ensure that it is not tampered with. I am trying to package the public key to decrypt and verify the signature with, but every time I try to execute the code as a different user than the one that generated the signature I get a failure on the signature. Most of my code is modified from sample code I have found since I am not as familiar with RSA encryption as I would like to be. Below is the code I was using and the code I thought I needed to use to get this working right... Any feedback would be greatly appreciated as I am quite lost at this point the original code I was working with was this, this code works fine as long as the user launching the program is the same one that signed the document originally... CspParameters cspParams = new CspParameters(); cspParams.KeyContainerName = "XML_DSIG_RSA_KEY"; cspParams.Flags = CspProviderFlags.UseMachineKeyStore; // Create a new RSA signing key and save it in the container. RSACryptoServiceProvider rsaKey = new RSACryptoServiceProvider(cspParams) { PersistKeyInCsp = true, }; This code is what I believe I should be doing but it's failing to verify the signature no matter what I do, regardless if it's the same user or a different one... RSACryptoServiceProvider rsaKey = new RSACryptoServiceProvider(); //Load the private key from xml file XmlDocument xmlPrivateKey = new XmlDocument(); xmlPrivateKey.Load("KeyPriv.xml"); rsaKey.FromXmlString(xmlPrivateKey.InnerXml); I believe this to have something to do with the key container name (Being a real dumbass here please excuse me) I am quite certain that this is the line that is both causing it to work in the first case and preventing it from working in the second case.... cspParams.KeyContainerName = "XML_DSIG_RSA_KEY"; Is there a way for me to sign/encrypt the XML with a private key when the application license is generated and then drop the public key in the app directory and use that to verify/decrypt the code? I can drop the encryption part if I can get the signature part working right. I was using it as a backup to obfuscate the origin of the license code I am keying from. Does any of this make sense? Am I a total dunce? Thanks for any help anyone can give me in this..

    I've posted the same question here and I've also got couple of good answers as well. While I was trying the same answers, I was getting compilation errors. Later I got to know that we are using .NET 2.0 and our existing application has no references to LINQ files. After searching in SO, i tried to figured out partly: public partial class Item { public object CHK { get; set; } public int SEL { get; set; } public string VALUE { get; set; } } Parsing: XmlDocument doc = new XmlDocument(); doc.LoadXml("<LISTBOX_ST> <item><CHK></CHK><SEL>00001</SEL><VALUE>val01</VALUE></item> <item><CHK></CHK><SEL>00002</SEL><VALUE>val02</VALUE></item> <item><CHK></CHK><SEL>00003</SEL><VALUE>val03</VALUE></item> <item><CHK></CHK><SEL>00004</SEL><VALUE>val04</VALUE></item> <item><CHK></CHK><SEL>00005</SEL><VALUE>val05</VALUE></item> </LISTBOX_ST>"); List<Item> _lbList = new List<Item>(); foreach (XmlNode node in doc.DocumentElement.ChildNodes) { string text = node.InnerText; //or loop through its children as well //HOW - TO - POPULATE THE ITEM OBJECT ?????? } listBox1.DataSource = _lbList; listBox1.DisplayMember = "VALUE"; listBox1.ValueMember = "SEL"; How to read two child nodes - SEL and VALUE of node and populate the same in the new Item DTO??

  • Connected host failed to respond (internal NAT address)

    - by MostRandom
    I'm writing my first C# web application that connects to an XML based service. It requires that I present a certificate and feed the XML stream. It seems to authenticate properly but then it gives the following error: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 10.1.10.4:3128 The funny thing is that I'm not on a proxy or anything like that. I'm connecting directly to the internet. At one point I we did use a proxy that with internal NAT address. So my question is: Does Visual Studio have some sort of default proxy setting that I need to change? This IP is no longer used for anything, so I know that I don't need to use any proxy authentication code. using System; using System.Data; using System.Configuration; using System.Collections; using System.Web; using System.Net; using System.Security.Cryptography.X509Certificates; using System.Web.Security; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Web.UI.HtmlControls; namespace WebApplication1 { public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { Uri requestURI = new Uri("*site omitted*"); //Create the Request Object HttpWebRequest pageRequest = (HttpWebRequest)WebRequest.Create(requestURI); //After installing the cert on the server export a client cert to the working directory as Deluxe.cer string certFile = "*certificate omitted*"; X509Certificate cert = X509Certificate.CreateFromCertFile(certFile); //Pull in your Data, if it is from an external xml as below or create an xml string with variables if a dynamic post is required. string xmlPath = "*XML omitted*"; System.Xml.XmlDocument passXML = new System.Xml.XmlDocument(); passXML.Load(xmlPath); //XML String with the data needed to pass string postData = passXML.OuterXml; //Set the Request Object parameters pageRequest.ContentType = "application/x-www-form-urlencoded"; pageRequest.Method = "POST"; pageRequest.AllowWriteStreamBuffering = false; pageRequest.AllowAutoRedirect = false; pageRequest.ClientCertificates.Add(cert); postData = "xml_data=" + Server.UrlEncode(postData); pageRequest.ContentLength = postData.Length; //Create the Post Stream Object System.IO.StreamWriter postStream = new System.IO.StreamWriter(pageRequest.GetRequestStream()); //Write the data to the post stream postStream.Write(postData); postStream.Flush(); postStream.Close(); //Set the Response Object HttpWebResponse postResponse = (HttpWebResponse)pageRequest.GetResponse();

  • Update tile notifcation with XML returned by web service

    - by tempid
    I have a Metro app in C# & XAML. The tile is updated periodically and I've used WebAPI to serve the tile notification XML. So far so good. I was then told that I cannot use WebAPI as the server that I was planning to host it on does not have .NET 4.5. No plans to install it anytime soon either. I had to change the WebAPI to a plain old Web service (.NET 3.5) which does the same thing - return tile notification XML. I've enabled HTTP-GET (I know, security concern) and was able to invoke the webservice like this - http://server/TileNotifications.asmx/[email protected] But ever since I made the switch, the tiles are not being updated. I've checked Fiddler and made sure the app is hitting the webservice and the XML is being returned correctly. But the tiles are not updated. If I replace it with the WebAPI, the tiles are updated. Do I need to do anything special with the web services? like decorating the web method with a custom attribute? Here's my web service code - [WebMethod] public XmlDocument GetTileData(string user) { // snip var xml = new XmlDocument(); xml.LoadXml(string.Format(@"<tile> <visual> <binding template='TileWideSmallImageAndText02'> <image id='1' src='http://server/images/{0}_wide.png'/> <text id='1'>Custom Field : {1}/text> <text id='2'>Custom Field : {2}</text> <text id='3'>Custom Field : {3}</text> </binding> <binding template='TileSquarePeekImageAndText01'> <image id='1' src='http://server/images/{0}_square.png'/> <text id='1'>Custom Field</text> <text id='2'>{1}</text> </binding> </visual> </tile>", value1, value2, value3, value4)); return xml; }

  • C# XPath id() not working?

    - by Iggyhopper
    I'm using C# and I'm stumped. Does it just not support id()? I have a large XML file, about 4-5 of them at ~400kb, so I need some speed and performance wherever I can get it. I use XmlDocument.SelectSingleNode("id('blahblahblah')") and it doesn't get the node by id. Am I going crazy or is it that C# XPath just doesn't support id()?

  • How to access and work with XML from API in C#

    - by Jarek
    My goal is to pull XML data from the API and load it to a sql server database. The frist step I'm attempting here is to access the data and display it. Once I get this to work I'll loop through each row and insert the values into a sql server database. When I try to run the code below nothing happens and when I paste the url directly into the browser I get this error "2010-03-08 04:24:17 Wallet exhausted: retry after 2010-03-08 05:23:58. 2010-03-08 05:23:58" To me it seems that every iteration of the foreach loop makes a call to the site and I get blocked for an hour. Am I retrieving data from the API in an incorrect manner? Is there some way to load the data into memory or an array then loop through that? Here's the bit of code I hacked together. using System; using System.Data.SqlClient; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using System.Xml; using System.Data; public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { try { string userID = "123"; string apiKey = "abc456"; string characterID = "789"; string url = "http://api.eve-online.com/char/WalletTransactions.xml.aspx?userID=" + userID + "&apiKey=" + apiKey + "&characterID=" + characterID; XmlDocument xmldoc = new XmlDocument(); xmldoc.Load(url); XmlNamespaceManager xnm1 = new XmlNamespaceManager(xmldoc.NameTable); XmlNodeList nList1 = xmldoc.SelectNodes("result/rowset/row", xnm1); foreach (XmlNode xNode in nList1) { Response.Write(xNode.InnerXml + "<br />"); } } catch (SqlException em) { Response.Write(em.Message); } } } Here's a sample of the xml <eveapi version="2"> <currentTime>2010-03-06 17:38:35</currentTime> <result> <rowset name="transactions" key="transactionID" columns="transactionDateTime,transactionID,quantity,typeName,typeID,price,clientID,clientName,stationID,stationName,transactionType,transactionFor"> <row transactionDateTime="2010-03-06 17:16:00" transactionID="1343566007" quantity="1" typeName="Co-Processor II" typeID="3888" price="1122999.00" clientID="1404318579" clientName="unseenstrike" stationID="60011572" stationName="Osmeden IX - Moon 6 - University of Caille School" transactionType="sell" transactionFor="personal" /> <row transactionDateTime="2010-03-06 17:15:00" transactionID="1343565894" quantity="1" typeName="Co-Processor II" typeID="3888" price="1150000.00" clientID="1404318579" clientName="unseenstrike" stationID="60011572" stationName="Osmeden IX - Moon 6 - University of Caille School" transactionType="sell" transactionFor="personal" /> </rowset> </result> <cachedUntil>2010-03-06 17:53:35</cachedUntil> </eveapi>

  • How do I avoid web method parameters using proxy classes?

    - by Alex Angas
    I have a serializable POCO called DataUnification.ClientData.ClientInfo in a .NET class library project A. It's used in a parameter for a web service defined in project B: public XmlDocument CreateNewClient(ClientInfo ci, string system) I now wish to call this web method from project C and use the original DataUnification.ClientData.ClientInfo type in the parameter. However due to the generated proxy class it has now become a different type: WebServices.ClientDataUnification.DataUnificationWebService.ClientInfo. As far as .NET is concerned these are not the same types. How can I get around this?

  • How do I use the information about exceptions a method throws in .NET in my code?

    - by dotnetdev
    For many methods in .NET, the exceptions they can potentially throw can be as many as 7-8 (one or two methods in XmlDocument, Load() being one I think, can throw this many exceptions). Does this mean I have to write 8 catch blocks to catch all of these exceptions (it is best practise to catch an exception with a specific exception block and not just a general catch block of type Exception). How do I use this information? Thanks
