  • What is the most semantic way to display a street address in HTML?

    - by tomk
    I have an address that is going to be displayed on a webpage, but it is not the address for the author of the page. How should this be coded to be semantic given the w3c recommendation of: The ADDRESS element may be used by authors to supply contact information for a document or a major part of a document such as a form. This element often appears at the beginning or end of a document.

  • Selenium navigation inside foreach loop

    - by smudgedlens
    I am having an issue with navigation. I get a list of rows from an html table. I iterate over the rows and scrape information from them. But there is also a link on the row that I click to go to more information related to the row to scrape. Then I navigate back to the page with the original table. This works for the first row, but for the subsequent rows, it throws an exception. I look at my row collection after the first time the link inside a row is clicked, and none of them have the correct values like they did before I clicked the link. I believe that there is something going on when I navigate to a different URL that I'm not getting. My code is below. How do I get this working so I can iterate over the parent table, click the links in each row, navigate to the child table, but still continue iterating over the rows in the parent table? private List<Document> getResults() { var documents = new List<Document>(); //Results IWebElement docsTable = this.webDriver.FindElements(By.TagName("table")) .Where(table => table.Text.Contains("Document List")) .FirstOrDefault(); var validDocRowRegex = new Regex(@"^(\d{3}\s+)"); var docRows = docsTable.FindElements(By.TagName("tr")) .Where(row => //It throws an exception with .FindElement() when there isn't one. row.FindElements(By.TagName("td")).FirstOrDefault() != null && //Yeah, I don't get this one either. I negate the match and so it works?? !validDocRowRegex.IsMatch( row.FindElement(By.TagName("td")).Text)) .ToList(); foreach (var docRow in docRows) { //Todo: find out why this is crashing on some documents. var cells = docRow.FindElements(By.TagName("td")); var document = new Document { DocID = Convert.ToInt32(cells.First().Text), PNum = Convert.ToInt32(cells[1].Text), AuthNum = Convert.ToInt32(cells[2].Text) }; //Go to history for the current document. cells.Where(cell => cell.FindElements(By.TagName("a")).FirstOrDefault() != null) .FirstOrDefault().Click(); //Todo: scrape child table. this.webDriver.Navigate().Back(); } return documents; }

  • DefaultStyledDocument.styleChanged(Style style) may not run in a timely manner?

    - by Paul Reiners
    I'm experiencing an intermittent problem with a class that extends javax.swing.text.DefaultStyledDocument. This document is being sent to a printer. Most of the time the formatting of the document looks correct, but once in a while it doesn't. It looks like some of the changes in the formatting have not been applied. I took a look at the DefaultStyledDocument.styleChanged(Style style) code: /** * Called when any of this document's styles have changed. * Subclasses may wish to be intelligent about what gets damaged. * * @param style The Style that has changed. */ protected void styleChanged(Style style) { // Only propagate change updated if have content if (getLength() != 0) { // lazily create a ChangeUpdateRunnable if (updateRunnable == null) { updateRunnable = new ChangeUpdateRunnable(); } // We may get a whole batch of these at once, so only // queue the runnable if it is not already pending synchronized(updateRunnable) { if (!updateRunnable.isPending) { SwingUtilities.invokeLater(updateRunnable); updateRunnable.isPending = true; } } } } /** * When run this creates a change event for the complete document * and fires it. */ class ChangeUpdateRunnable implements Runnable { boolean isPending = false; public void run() { synchronized(this) { isPending = false; } try { writeLock(); DefaultDocumentEvent dde = new DefaultDocumentEvent(0, getLength(), DocumentEvent.EventType.CHANGE); dde.end(); fireChangedUpdate(dde); } finally { writeUnlock(); } } } Does the fact that SwingUtilities.invokeLater(updateRunnable) is called, rather than invokeAndWait(updateRunnable), mean that I can't count on my formatting changes appearing in the document before it is rendered? If that is the case, is there a way to ensure that I don't proceed with rendering until the updates have occurred?

  • How can I specify dependencies in the manifest file and then to include it into my .jar file?

    - by Roman
    I generated .class files by the following command: javac -cp \directoryName\external.jar myPackageDirectory\First.java myPackageDirectory\Second.java I needed to use -cp during compilation and name of .jar file of an "external" library (external.jar) to be able to use this library from my code. Using my .class files I have generated my .jar file in the following way: jar cfm app.jar manifest.txt myPackageDirectory\*.class manifest.txt contains just one line: Main-Class: myPackageName.First My problem is that I am not sure that I will be able to run my .jar file on other computers. I think so because during the compilation I specified the location of the .jar file of the external library. So, my .class files (included into the .jar file will try to find the .jar file of the external library in a specific directory and there is no guaranty that that the .jar file of the external library will be in the same directory as on the my computer. I heard that the above problem can be solved by a usage of a MANIFEST file that I include in my own jar, and which will list dependency locations but I do not understand how it works. I do need to specify location of the "external.jar" at the compilation stage (otherwise the compiler complains).

  • In a Visual Studio C++ project with /clr, are its dependencies also compiled to managed code?

    - by Michael
    To be a bit more clear. If I have a Visual Studio C++ solution that has two projects, say a static library with CLR support turned off, and a second project with CLR support turned on that depends on this static library, does the static library get compiled as managed code? What about libraries that the CLR project uses that are external to this solution, do they also get compiled as managed code?

  • JavaScript date suffix formatting

    - by TexasB
    I have done my due diligence in investigating this and not had any success yet. Being rather green with JavaScript I am seeking some help. I am wanting to display the date NOV2012<br> 2<sup>nd</sup><br> 5:00 PM I have everything working (not my script) except being able to get the date suffix to change to st, nd, rd, or th as the case may be. This is what I have: <pre> <abbr title="Month"> <script type="text/javascript"> var d=new Date(); var month=new Array(12); month[0]="Jan"; month[1]="Feb"; month[2]="Mar"; month[3]="Apr"; month[4]="May"; month[5]="Jun"; month[6]="Jul"; month[7]="Aug"; month[8]="Sep"; month[9]="Oct"; month[10]="Nov"; month[11]="Dec"; document.write(month[d.getMonth()]); </script></abbr> <script type="text/javascript"> var d = new Date() document.write(d.getDate()) ordinal : function (number) { var d = number % 10; return (~~ (number % 100 / 10) === 1) ? 'th' : (d === 1) ? 'st' : (d === 2) ? 'nd' : (d === 3) ? 'rd' : 'th'; } }); </script> <sup>%</sup> <abbr><script type="text/javascript"> var d = new Date() document.write(d.getFullYear()) </script></abbr> <sub> <script type="text/javascript"> <!-- var currentTime = new Date() var hours = currentTime.getHours() var minutes = currentTime.getMinutes() if (minutes < 10){ minutes = "0" + minutes } document.write(hours + ":" + minutes + " ") if(hours > 11){ document.write("PM") } else { document.write("AM") } //--> </script> </sub> </pre> I know the issue is with this part: <pre> <script type="text/javascript"> var d = new Date() document.write(d.getDate()) ordinal : function (number) { var d = number % 10; return (~~ (number % 100 / 10) === 1) ? 'th' : (d === 1) ? 'st' : (d === 2) ? 'nd' : (d === 3) ? 'rd' : 'th'; } }); </script> < sup > % < /sup > </pre> but I can't seem to work out the right fix.

  • How to Automatically Refresh Data on Page Using Ajax on an Interval?

    - by Karnak
    I would like to load an XML file every 30 seconds and display its contents inside an HTML page. So far I know how to load the file, but I don't know how to automatically refresh it and display its updated contents. It would also be great if it did some error checking and if it displayed error.png image when it's not able to load data.xml file. Here is my code: <head> <script> window.XMLHttpRequest { xmlhttp = new XMLHttpRequest(); } xmlhttp.open("GET", "data.xml", false); xmlhttp.send(); loadXMLDoc = xmlhttp.responseXML; f = loadXMLDoc.getElementsByTagName("foo") function buildBar(i) { qux = (f[i].getElementsByTagName("qux")[0].childNodes[0].nodeValue); document.getElementById("displayBar").innerHTML = qux; } </script> </head> <body> <script> document.write("<ul>"); for (var i = 0; i < f.length; i++) { document.write("<li onclick='buildBar(" + i + ")'>"); document.write(f[i].getElementsByTagName("bar")[0].childNodes[0].nodeValue); document.write("</li>"); } document.write("</ul>"); </script> <div id="displayBar"> </div> </body> After searching the internet for a few hours I found many examples on how to do this, but I didn't know how to implement it in my particular case. I am not a programmer, so please be kind. I would really appriciate any help. It would mean a lot.

  • Code management in different projects with different svn repositories

    - by uzay95
    First of all I want to tell you what kind of system I have and I want to build on. 1- A Solution (has) a- Shared Class Library project (which is for lots of different solutions) b- Another Class Library project (which is only for this solution) c- Web Application project (which main part of this solution) d- Shared Web Service project (which also serves for different solutions) 2- B Solution (has) a- Shared Class Library project (which is for lots of different solutions) c- Windows Form Application project (which is main part of this solution) d- Web Service project (which also serves for different solutions) and other projects like that.... I am using xp-dev.com as our svn repository server. And I opened different projects for these items (Shared Class Library, Web Service project, Windows Form Application project, Web Application project, Another Class Library project) . I want to do the versioning of all these projects of course. My first question is, should I put each project(one solution) to one svn repository to get their revision number later on? Or should I put each of them to different svn repository and keep( write down) their correct version number that is used to publish/deploy every solution? If I use one svn for each project(Shared Class Lib, Web App, Shared Web Service....) how can I relate the right svn address and version on VS.2010 within the real solution? So, how do you manage your repositories and projects?

    Hi everyone, I want to add an on blur event to a dojo timetextbox but the event never been runned so the declaration of the timetextbox is like this: <label>End</label><input id="endp" name="endp" onBlur="calculateTimeSpent2(startp,endp,output);" /> the javascript function is like this: function calculateTimeSpent2(startp,endp,outputp) { var tmp0=document.getElementById('startp').value.split(':'); var tmp1=document.getElementById('endp').value.split(':'); if (tmp0[0]!='' && tmp1[0]!='') { var val1= findtime(tmp0[0],tmp0[1],tmp1[0],tmp1[1]); var tmp=val1.split(':'); if (tmp[0].indexOf('-')==-1) document.getElementById('outputp').value=val1; else { alert ("Start Time must be lower than End Time "); document.getElementById('endp').focus(); } } } I don't understand why dojo didn't execute the event correctly while loosing the focus.

  • Start SharePoint workflow only with new file versions

    - by NeiOliver
    I am trying to create a workflow to send an e-mail whenever a new version of a file is uploaded to a Document Library. The Document Library has lots of fields that, if updated, will create a new version of the ListItem, but I don't want to start the workflow for this cases. Only when a new version of the document is uploaded (including the first version) I want the workflow started. My document library does not need approval, only major versions are enabled and it does not need to checkout files before editing. Is there a way of doing this, even programmatically?

  • Data storage advice needed: Best way to store location + time data?

    - by sobedai
    I have a project in mind that will require the majority of queries to be keyed off of lat/long as well as date + time. Initially, I was thinking of a standard RDBMS where lat, long, and the datetime field are properly indexed. Then, I began thinking of a document based system where the document was essentially a timestamp and each document has lat/long with in it. Each document could have n objects associated with it. I'm looking for advice on what would be the best type of storage engine for this sort of thing is - which of the above idea would be better or if there is something else completely that is the ideal solution.

  • Need help with tweaking a Dropdown with three options, user selects one - a hidden div appears with correct fields

    - by Jack
    Hello Again, I posted a question on here and got an answer within minutes I'm hoping the wizards on here can help me again. Okay so I'm using a script I found online to try and add this function to a shopping cart form. Here's the setup. I have a payment method dropdown with Visa, Mastercard and Bank Withdrawal as the options. For the credit cards I have one hidden div with a certain set of fields, and for the bank I have another hidden div. Each of the divs have named ID's - #payCredit and #payBank The css for both have margin: 0px and display: none; Here's a peice of javascript I used successfuly on a shipping address checkbox `function toggleLayer( whichLayer ) { var elem, vis; if( document.getElementById ) // this is the way the standards work elem = document.getElementById( whichLayer ); else if( document.all ) // this is the way old msie versions work elem = document.all[whichLayer]; else if( document.layers ) // this is the way nn4 works elem = document.layers[whichLayer]; vis = elem.style; // if the style.display value is blank we try to figure it out here if(vis.display==''&&elem.offsetWidth!=undefined&&elem.offsetHeight!=undefined) vis.display = (elem.offsetWidth!=0&&elem.offsetHeight!=0)?'block':'none'; vis.display = (vis.display==''||vis.display=='block')?'none':'block'; }` I was hoping I could change it slightly to meet my needs. Here's the dropdown <label>Payment Method:</label> <select name="payment" id="payment" class="dropdown3" style="width:8em"> <option selected="selected">Select</option> <option value="Visa" onclick="javascript:toggleLayer('payCredit');">Visa</option> <option value="MasterCard" onclick="javascript:toggleLayer('payCredit');">Mastercard</option> <option value="Direct" onclick="javascript:toggleLayer('payBank');">Direct Withdraw</option> </select></li> The current result is that it kinda works. I can open the dropdown and select Visa and it appears, if I select Visa again it disappears, if I select Visa and then select bank, both appear. You can see what i'm working on here - http://test.sharevetcare.com/bestfriends/cart3.html
