• Storing rich text documents

  - by David Veeneman

  This is a follow-up to another question I asked earlier today. I am creating a desktop app that stores rich text documents created in WPF (in a RichTextBox control). The app uses SQL Compact, and up until now, I had planned to store each document in a binary column in the database. I am rethinking that approach. Would it be better practice to store each rich text document in the file system, rather than saving it to the database? I figure I could put the documents in the same folder with the database, then store a relative path to each document in its database record, along with other information about the document (tags and so on). I'd like to know some pros and cons of that approach, along with ideas of what is generally considered best practice for this sort of thing. Thanks for your help.

• positioning a jquery dialog that is inside an iframe realtive to the parent window

  - by guy schaller

  hallo all i have a site which has a very big scroll on it, and there is an iframe in the middle set to have no scroll and its height is 3000 anyway the document being opened in the iframe has a jquery dialog in it. when im looking at the top of the parent and click a button inside the iframe that opens the dialog the dialog opens at the middle of the iframe and i cant see it... thats because its doing its calcualtions based on the document not the top document how can i change that? so if my scroll was all the way down in the parent the dialog inside the iframe will open at the bottom of the iframe where i can see it.. in other words realtive to positon of parent document. thanks in advance

  Hi I am having trouble uploading a file.

• Duplicate ID/indexes and looping

  - by Justin Alexander

  I realize having two elements in the same html doc with the same ID is wrong, bad, immoral, and will lead to global warming. But... I'm trying to write an XSS widgit, so I really have no control over the quality of the parent web page. I loop through document.images to retrieve a list of images on the page. I perform an action on each one. for(img in document.images){ ... } i've also tried for(var i=0;i<document.images.length;i++){ ... } in both cases it allows me to loop through all of the elements, BUT when trying trying to reference an object with a duplicate ID, I always get the first (in order of the html). When using debugger in IE8 i'm able to see that both elements ARE listed, but that they both have the same index (in IE the index of the document.images is either sequential or matches the image ID) Does anyone have a better solution?

• WHERE x = @x OR @x IS NULL

  - by steveh99999

  Every SQL DBA and developer should read the blog of MVP Erland Sommarskog – but particularly  his article on dynamic search conditions in T-SQL. I’ve linked above to his SQL 2005 article but his 2008 version is also a must-read. I seem to regularly come across uses of the SQL in the title above… Erland’s article explains in detail why this is inefficient, but I came across a nice example recently… A stored procedure contained the following code :- WHERE @Name is null or [Name] like @Name as a nonclustered index exists on the Name column, you might assume this would be handled efficiently by SQL Server. However, I got the following output from SET STATISTICS IO Table 'xxxxx'. Scan count 15, logical reads 47760, physical reads 9, read-ahead reads 13872, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0. Note the high number of logical reads… After a bit of investigation, we found that @Name could never actually be set to NULL in this particular example. ie the @x IS NULL was spurious… So, we changed the call to WHERE  [Name] like @Name Now, how much more efficient is this code ? Table 'xxxxx'. Scan count 3, logical reads 24, physical reads 0, read-ahead reads 0, lob logical reads 0, lob physical reads 0, lob read-ahead reads 0 A nice easy win in this case…… a full index scan has been replaced by a significantly more efficient index seek. I managed to recreate the same behaviour on Adventureworks – here’s a quick query to demonstrate :- USE adventureworks SET STATISTICS IO ON DECLARE @id INT = 51721 SELECT * FROM Sales.SalesOrderDetail WHERE @id IS NULL OR salesorderid = @id SELECT * FROM Sales.SalesOrderDetail WHERE salesorderid = @id Take a look at the STATISTICS IO output and compare the actual query plans used to prove the impact of  WHERE @id IS NULL. And just to follow some of Erland’s advice – here’s how you could get similar performance if it was possible that @id could actually sometimes contain NULL. DECLARE @sql NVARCHAR(4000), @parameterlist NVARCHAR(4000) DECLARE @id INT = 51721 – or change to NULL to prove query is functionally correct SET @sql = 'SELECT * FROM Sales.SalesOrderDetail WHERE 1 = 1' IF @id IS NOT NULL SET @sql = @sql + ' AND salesorderid = @id' IF @id IS NULL SET @sql = @sql + ' AND salesorderid IS NULL' SET @parameterlist = '@id INT' EXEC sp_executesql @sql, @parameterlist,@id Sometimes I think we focus too much on hardware and SQL Server configuration – when really the answer is focus on writing efficient SQL.

• Easyslider content loading sooner than I would like.

  - by Jason

  I am using a jquery easyslider on a page and also pulling some rss feeds using php. Pulling the feeds is taking a long time and as a result delaying the load of the easy slider until after the feeds have been pulled in. This can be seen here: http://perksconsulting.com/dev/ I am looking for a way to display a loader image in the space where the easy slider is so the images do not appear stacked vertically for a few seconds while the php is interpreted by the server, but I have never used a loader image and am not sure how I would do that. I am currently using this script to hide the page contents until everything is loaded, but the one thing it is not hiding is the images from the easy slider: <SCRIPT TYPE="text/javascript" LANGUAGE="javascript"> function waitPreloadPage() { //DOM if (document.getElementById){ document.getElementById('prepage').style.visibility='hidden'; }else{ if (document.layers){ //NS4 document.prepage.visibility = 'hidden'; } else { //IE4 document.all.prepage.style.visibility = 'hidden'; } } } // End --> </SCRIPT> Ideally I would like to be able to display a loading image in place of the slider in the middle of the page until everything loads. Could anyone tell me how to do this? Thank you.

  Hi All, I am using asp:button to create a keyboard with A-Z and 0-9 for touch screen using Java script. This keyboard is linked with one textbox. If we click one button corresponding text will be displayed on the textbox. Its working fine. I have included the autocomplete feature to this textbox using jquery JQuery Autocomplete. Problem: The autocomplete is not working if i my user define keyboard. How to modify my key buttons as keyboard keys? Is it possible? Is there any other way to achieve this? Code: <asp:TextBox ID="txtSearch" runat="server"></asp:TextBox> <asp:Button ID="zero" runat="server" Text="0" CssClass="myclass" OnClientClick="return typeLetter(this);" TabIndex="20"/> function typeLetter(currentbutton) { if (previousActiveElement != null) { if (previousActiveElement == 'antSearchText'){ var position = document.getElementById('position').value; if (position == '') { alert('chk position'); } else { var existingString = document.getElementById(previousActiveElement).value; var beforeString = existingString.substring(0, position); var afterString = existingString.substring(position, existingString.length); document.getElementById(previousActiveElement).value = beforeString + currentbutton.value + afterString; setCaretPosition(document.getElementById(previousActiveElement), parseInt(position) + 1); setCaretPosition(document.getElementById(previousActiveElement), parseInt(position) + 1); } } } return false; }

• xmlns='' was not expected when deserializing nested classes

  - by Mavrik

  I have a problem when attempting to serialize class on a server, send it to the client and deserialize is on the destination. On the server I have the following two classes: [XmlRoot("StatusUpdate")] public class GameStatusUpdate { public GameStatusUpdate() {} public GameStatusUpdate(Player[] players, Command command) { this.Players = players; this.Update = command; } [XmlArray("Players")] public Player[] Players { get; set; } [XmlElement("Command")] public Command Update { get; set; } } and [XmlRoot("Player")] public class Player { public Player() {} public Player(PlayerColors color) { Color = color; ... } [XmlAttribute("Color")] public PlayerColors Color { get; set; } [XmlAttribute("X")] public int X { get; set; } [XmlAttribute("Y")] public int Y { get; set; } } (The missing types are all enums). This generates the following XML on serialization: <?xml version="1.0" encoding="utf-16"?> <StatusUpdate> <Players> <Player Color="Cyan" X="67" Y="32" /> </Players> <Command>StartGame</Command> </StatusUpdate> On the client side, I'm attempting to deserialize that into following classes: [XmlRoot("StatusUpdate")] public class StatusUpdate { public StatusUpdate() { } [XmlArray("Players")] [XmlArrayItem("Player")] public PlayerInfo[] Players { get; set; } [XmlElement("Command")] public Command Update { get; set; } } and [XmlRoot("Player")] public class PlayerInfo { public PlayerInfo() { } [XmlAttribute("X")] public int X { get; set; } [XmlAttribute("Y")] public int Y { get; set; } [XmlAttribute("Color")] public PlayerColor Color { get; set; } } However, the deserializer throws an exception: There is an error in XML document (2, 2). <StatusUpdate xmlns=''> was not expected. What am I missing or doing wrong?

• Loading and removing images with DOM, Javascript

  - by jesse

  I'm new to DOM and I'm having trouble removing multiple images that I loaded this loads 7 images (1.jpg, 2.jpg, etc..) function loadImages() { for (var i = 1; i < 8; i++ ) { var img = document.createElement("img"); img.src = "images/"+i+".jpg"; var idName = "img"+i+""; document.getElementById(idName).appendChild(img); } } this should remove all of them, but doesn't.. I think it breaks at the removeChild line. function removeImages() { for (var i = 1; i < 8; i++ ) { var idName = "img"+i+""; var d = document.getElementById(idName); d.removeChild(document.getElementById(img)); } } I think I'm doing something fundamentally wrong, because I don't fully understand how this works...

• generating dynamic word documents for mass mailing

  - by bluesystem

  I need to generate a mass mailing based on a word document model with PHP. Given is a database with the adresses and the data that need to be filled in my word model. I want to generate a single word document with the different adresses and field contents from the database. We have a Linux server and the COM object is not avalaible. Is there a ready to use class to do this? Did you had any experiance with PHPWord? What is the best practice in this case? In the ideal case the client should just upload th word master document, with the fields that need to be filled and then fusioned to a multiple pages word document containing the whole mailing.

• How can I append and execute a script inside an iframe in a cross browser way (specifically IE!)?

  - by agmin

  Background: I need to load ad scripts after the DOM has loaded. Because many of the scripts use document.write() and other potentially bad functions to run after the DOM has loaded, I want to load the scripts inside an iframe. So when the ad needs to be shown, an event is triggered which does the following: var iframe = document.createElement('iframe'); iframe.setAttribute('id', 'iframeId'); iframe.setAttribute('src', 'about:blank'); var adContainer = document.getElementById('AdContainer'); adContainer.appendChild(iframe); var val = '<html><head></head><body>'; val += '<scr' + 'ipt type="text/javascript" src="' + url + '"></scr' + 'ipt>'; val += '</body></html>'; If I don't assign the html and body tags to val, the script automatically gets appended to the head of the iframe and fails to execute in FF. In IE, the script doesn't execute with or without the head/body/html tags. var doc = iframe.contentWindow || iframe.contentDocument; if (doc.document){ doc = doc.document } doc.open(); doc.write(val); doc.close(); I found this last bit of code here: http://stackoverflow.com/questions/1591135/why-does-appending-a-script-to-a-dynamically-created-iframe-seem-to-run-the-s. I do NOT want to load jquery in the iframe though, I just want to append a script and have it execute. My current solution seems to work great in FF and Webkit. However, IE doesn't execute the script. The script is written to the page, but doesn't start running. Is there a better way to append the script to the iframe so it will run cross browser? Or is it possible to tell IE to run the script? I know that I could load an external document with the ad script via the iframe, but I don't want to make the extra call to my server if I can do this dynamically. Also, I've tried using appendChild() on the iframe's body to insert the script, but since the script element is created outside the iframe's DOM this doesn't seem to work.

• JavaScript date suffix formatting

I am wanting to display the date NOV2012<br> 2^nd<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.

• 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; }

" << a.get(0) << " " << a.get(1) << " " << a.get(3) << std::endl; By now I have an AutoClass with a working "set" member: class nothing {}; template < typename T1 = nothing, typename T2 = nothing, typename T3 = nothing, typename T4 = nothing, typename T5 = nothing, typename T6 = nothing> class AutoClass; template <> class AutoClass<nothing, nothing, nothing, nothing, nothing, nothing> { public: template <typename U> void set(int n,U v){} }; template < typename T1, typename T2, typename T3, typename T4, typename T5, typename T6> class AutoClass: AutoClass<T2,T3,T4,T5,T6> { public: T1 V; template <typename U> void set(int n,U v) { if (n <= 0) V = v; else AutoClass<T2,T3,T4,T5,T6>::set(n-1,v); } }; and I started to have problems implementing the corresponding "get". This approach doesn't compile: template < typename T1, typename T2, typename T3, typename T4, typename T5, typename T6> class AutoClass: AutoClass<T2,T3,T4,T5,T6> { public: T1 V; template <typename U> void set(int n,U v) { if (n <= 0) V = v; else AutoClass<T2,T3,T4,T5,T6>::set(n-1,v); } template <typename W> W get(int n) { if (n <= 0) return V; else return AutoClass<T2,T3,T4,T5,T6>::get(n-1); } template <> T1 get(int n) { if (n <= 0) return V; else return AutoClass<T2,T3,T4,T5,T6>::get(n-1); } }; Besides, it seems I need to implement get for the <nothing, nothing, nothing, nothing, nothing, nothing> specialization. Any Idea on how to solve this?
