  • Change Border in Excel left,right,bottom and top

    - by Le Viet Hung
    Firstly i changed color borders of my sheet to white, because i want to have a white sheet. Then i made some headers and want to make border around it. The Problem is it made borders between the values in header but top, down are not seenable. My code: xlWorkSheet5.Columns.Borders.Color = System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.White); // Color Sheet5 to white, BusLoad xlWorkSheet5.Columns.NumberFormat = "@"; Excel.Range rng = (Excel.Range)xlWorkSheet5.get_Range("A7","J7"); rng.RowHeight = 25.5; rng.BorderAround2(Excel.XlLineStyle.xlContinuous, Excel.XlBorderWeight.xlHairline, Excel.XlColorIndex.xlColorIndexAutomatic, Excel.XlColorIndex.xlColorIndexAutomatic); rng.Borders.LineStyle = Excel.XlLineStyle.xlContinuous; rng.Borders.Weight = 1d; rng.Font.Bold = true; rng.HorizontalAlignment = Microsoft.Office.Interop.Excel.XlHAlign.xlHAlignCenter; rng.Interior.Color = System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.LightGray);

  • Alpha transparent PNGs not displaying correctly in Mobile Safari

    - by worksology
    I'm using some semi-transparent PNGs as background-images on various websites. These are usually something like a 1x1 image with a 30-percent opaque white layer. I've noticed that Mobile Safari does not display them correctly, giving them a darker/grayish tint. I've created a couple test pages to illustrate. View them both in your normal browser, and then on Mobile Safari, and you should see what I mean. This shows 11 red images of varying opacities on white: http://thecompleteworks.org/alpha-tests/index-red.html This shows 11 white images of varying opacities on blue: http://thecompleteworks.org/alpha-tests/index.html Is this a MobileSafari bug (I couldn't imagine so), or do I need to do something different, either to my pages or PNGs? (Here's how I create the PNGs: In Photoshop, create a 1x1 transparent canvas. Draw a white rectangle in Layer 1. Set opacity to, say 30 percent, Save for Web as 24-bit PNG with transparency.)

  • OpenGLES mix and match blending options complicated question

    - by DevDevDev
    So I have a background line drawing, black and white. I want to be able to draw over this, keeping the black lines in there, and drawing only where it is white. I can do this by using glBlendFunc(GL_DST_COLOR, GL_ONE_MINUS_SRC_ALPHA); And the black stays black and white gets whatever color I want. However in the white areas, I want to be able to draw some color, pick to another color and then blend. However this doesn't work because the blend function is messed up. So what I was thinking is having a linedrawing framebuffer, and a user-drawing framebuffer. The user draws into the userdrawing framebuffer, with a different blending, and then I switch blending options and draw into the linedrawing framebuffer. But i don't know enough OpenGL to say whether or not this will work or is a stupid idea. Thanks a lot

  • How apply a storyboard to a Label programmatically ?

    - by ThitoO
    Hi :), I've a little problem, I'd search google and my Wpf's books but I don't found any answer :( I have created a little storyboard : <Storyboard x:Key="whiteAnim" Duration="1"> <ColorAnimation By="Black" To="White" Storyboard.TargetProperty="Background" x:Name="step1"/> <ColorAnimation By="White" To="Black" Storyboard.TargetProperty="Background" x:Name="step2"/> </Storyboard> This animation will change background color from black to white, and from white to black. I want to "apply" this storyboard to a Label : Label label = new Label(); label.Content = "My label"; I'm looking for a method like "label.StartStoryboard(--myStoryboard--), do you have any ideas ? Thank you :)

  • Why does calling IEnumerable<string>.Count() create an additional assembly dependency ?

    - by Gishu
    Assume this chain of dll references Tests.dll >> Automation.dll >> White.Core.dll with the following line of code in Tests.dll, where everything builds result.MissingPaths Now when I change this to result.MissingPaths.Count() I get the following build error for Tests.dll "White.UIItem is not defined in an assembly that is not referenced. You must add a reference to White.Core.dll." And I don't want to do that because it breaks my layering. Here is the type definition for result, which is in Automation.dll public class HasResult { public HasResult(IEnumerable<string> missingPaths ) { MissingPaths = missingPaths; } public IEnumerable<string> MissingPaths { get; set; } public bool AllExist { get { return !MissingPaths.Any(); } } } Down the call chain the input param to this ctor is created via (The TreeNode class is in White.Core.dll) assetPaths.Where(assetPath => !FindTreeNodeUsingCache(treeHandle, assetPath)); Why does this dependency leak when calling Count() on IEnumerable ? I then suspected that lazy evaluation was causing this (for some reason) - so I slotted in an ToArray() in the above line but didn't work. Update 2011 01 07: Curiouser and Curiouser! it won't build until I add a White.Core reference. So I add a reference and build it (in order to find the elusive dependency source). Open it up in Reflector and the only references listed are Automation, mscorlib, System.core and NUnit. So the compiler threw away the White reference as it was not needed. ILDASM also confirms that there is no White AssemblyRef entry. Any ideas on how to get to the bottom of this thing (primarily for 'now I wanna know why' reasons)? What are the chances that this is an VS2010/MSBuild bug? Update 2011 01 07 #2 As per Shimmy's suggestion, tried calling the method explcitly as an extension method Enumerable.Count(result.MissingPaths) and it stops cribbing (not sure why). However I moved some code around after that and now I'm getting the same issue at a different location using IEnumerable - this time reading and filtering lines out of a file on disk (totally unrelated to White). Seems like it's a 'symptom-fix'. var lines = File.ReadLines(aFilePath).ToArray(); once again, if I remove the ToArray() it compiles again - it seems that any method that causes the enumerable to be evaluated (ToArray, Count, ToList, etc.) causes this. Let me try and get a working tiny-app to demo this issue... Update 2011 01 07 #3 Phew! More information.. It turns out the problem is just in one source file - this file is LINQ-phobic. Any call to an Enumerable extension method has to be explicitly called out. The refactorings that I did caused a new method to be moved into this source file, which had some LINQ :) Still no clue as to why this class dislikes LINQ. using System; using System.Collections.Generic; using System.IO; using System.Linq; using G.S.OurAutomation.Constants; using G.S.OurAutomation.Framework; using NUnit.Framework; namespace G.S.AcceptanceTests { public abstract class ConfigureThingBase : OurTestFixture { .... private static IEnumerable<string> GetExpectedThingsFor(string param) { // even this won't compile - although it compiles fine in an adjoining source file in the same assembly //IEnumerable<string> s = new string[0]; //Console.WriteLine(s.Count()); // this is the line that is now causing a build failure // var expectedInfo = File.ReadLines(someCsvFilePath)) // .Where(line => !line.StartsWith("REM", StringComparison.InvariantCultureIgnoreCase)) // .Select(line => line.Replace("%PLACEHOLDER%", param)) // .ToArray(); // Unrolling the LINQ above removes the build error var expectedInfo = Enumerable.ToArray( Enumerable.Select( Enumerable.Where( File.ReadLines(someCsvFilePath)), line => !line.StartsWith("REM", StringComparison.InvariantCultureIgnoreCase)), line => line.Replace("%PLACEHOLDER%", param)));

  • Word-wrap grid cells in Ext JS

    - by richardtallent
    (This is not a question per se, I'm documenting a solution I found using Ext JS 3.1.0. But, feel free to answer if you know of a better solution!) The Column config for an Ext JS Grid object does not have a native way to allow word-wrapped text, but there is a css property to override the inline CSS of the TD elements created by the grid. Unfortunately, the TD elements contain a DIV element wrapping the content, and that DIV is set to white-space:nowrap by Ext JS's stylesheet, so overriding the TD CSS does no good. I added the following to my main CSS file, a simple fix that appears to not break any grid functionality, but allows any white-space setting I apply to the TD to pass through to the DIV. .x-grid3-cell { /* TD is defaulted to word-wrap. Turn it off so it can be turned on for specific columns. */ white-space:nowrap; } .x-grid3-cell-inner { /* Inherit DIV's white-space from TD parent, since DIV's inline style is not accessible in the column definition. */ white-space:inherit; } YMMV, but it works for me, wanted to get it out there as a solution since I couldn't find a working solution by searching the Interwebs.

  • Override transparency color when converting transparent PNG to JPG

    - by Alexander Malfait
    I'm using Dragonfly to generate thumbnail images in a Rails app. I'm serving all picture images as JPG's. Now the client is uploading transparent PNG files, like this one: http://www.ibanez.co.jp/products/images/eg2010/ART120_TRF_12_02.png Dragonfly uses RMagick to convert these images to JPG. The problem is that it converts the PNG images to JPG with a black background, and my site's design requires a white background. I've tried to override it like this: encoded_image = Magick::Image.from_blob(image.data).first if encoded_image.format.downcase == format image # do nothing else encoded_image.format = format encoded_image.background_color = "white" encoded_image.transparent_color = "white" encoded_image.to_blob end But the produced JPG images still contain a black background. Does anyone know how to beat RMagick into using a white background when converting the transparent layer? I know I could just serve as PNG, but then the images are 10 times as large, and the site is already pretty bandwidth heavy.

  • jquery manipulate a tags with .css()

    - by jesse
    I need to change the font color of a div with the id name "nav" to white. I did: $("#nav").css("color","white"); This works for all the text that isn't wrapped in < a tags but I need those changed too. I tried adding: $("a").css("color","white"); But that doesn't work. I also tried: var changeAColor = document.getElementsByTagName("a") $(changeAColor).css("color","white"); Any ideas appreciated.

  • Changing Color with LinearLayout and TextView in Java (Android)

    - by Rob S.
    I'm a relatively new Android developer and I noticed what seems like an oddity to me that I'm hoping someone can explain. I have LinearLayout ll. This line of code fails for me when executed: ll.setBackgroundColor(R.color.white); However this line of code works: ll.setBackgroundResource(R.color.white); I assume its simply because I have white defined in my resources. However, I've also tried passing 0xFFFFFF in setBackgroundColor() and that doesn't work either. Similarly with my TextView text this line of code fails when executed: text.setTextColor(R.color.white); I can see my TextView so I know I initialized it correctly (like my LinearLayout which I can also see). So I guess my question boils down to: How do I properly use LinearLayout.setBackgroundColor() and TextView.setTextColor() ? Thanks a ton in advance. I've read through the docs and tried to find information online via googling and haven't come up with anything.

  • Using selector to change TextView text color

    - by rafuru
    I'm trying to use a TextView to define the style of a TabWidget on a tabhost. I just created a selector for bgcolor and works fine, but i want to make a selector for textColor but the text color don't change: This is my tab_text_selector.xml: <?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android" > <item android:state_selected="true" android:color="@android:color/white" /> <item android:state_focused="true" android:color="@android:color/white" /> <item android:state_pressed="true" android:color="@android:color/white" /> </selector> And this is the code when i'm trying to use on a textView: TextView txtTab=new TextView(this); txtTab.setTextColor(R.drawable.tab_text_selector); txtTab.setBackgroundResource(R.drawable.tab_bg_selector); txtTab.setGravity(Gravity.CENTER); txtTab.setText("Agregar Idea"); I know the text color must be white in any case but it doesn't.

    Hi, Here is my working page. I attached buttons to white bishop and you can move around but left images are overlapped by right images. I think the problem is with CSS.

  • Changing UI color in Eclipse

    - by Lo'oris
    I'm aware of this topic: I've used it to change most of the editor colors, and that's great. But that wasn't enought, there's still too much white (and I need to change it because it hurts my eyes). I've searched in the preferences (both using Eclipse itself and editing the files) for instances of while (255,255,255) and changed them all. Looks like I'm missing something. too much white in the UI: http://www.imagebanana.com/view/gy89qf7/eclipse_too_much_white_1.png totally white in this screen: http://www.imagebanana.com/view/j8282wf/eclipse_too_much_white_2.png

  • add_shown & add_hiding ModalPopupExtender Events

    - by Yousef_Jadallah
        In this topic, I’ll discuss the Client events we usually need while using ModalPopupExtender. The add_shown fires when the ModalPopupExtender had shown and add_hiding fires when the user cancels it by CancelControlID,note that it fires before hiding the modal. They are useful in many cases, for example may you need to set focus to specific Textbox when the user display the modal, or if you need to reset the controls values inside the Modal after it has been hidden. To declare Client event either in pageLoad javascript function or you can attach the function by Sys.Application.add_load like this: Sys.Application.add_load(modalInit); function modalInit() { var modalPopup = $find('mpeID'); modalPopup.add_hiding(onHiding); } function onHiding(sender, args) { } .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; }   I’ll use the first way in the current example. So lets start with the illustration:   1- In this example am using simple panel which contain UserName and Password Textboxes besides submit and cancel buttons, this Panel will be used as PopupControlID in the ModalPopupExtender : <asp:Panel ID="panModal" runat="server" Height="180px" Width="300px" style="display:none" CssClass="ModalWindow"> <table width="100%" > <tr> <td> User Name </td> <td> <asp:TextBox ID="txtName" runat="server"></asp:TextBox> </td> </tr> <tr> <td> Password </td> <td> <asp:TextBox ID="txtPassword" runat="server" TextMode="Password"></asp:TextBox> </td> </tr> </table> <br /> <asp:Button ID="btnSubmit" runat="server" Text="Submit" /> <asp:Button ID="btnCancel" runat="server" Text="Cancel" /> </asp:Panel>   You can use this simple style for the Panel : <style type="text/css"> .ModalWindow { border: solid; border-width:3px; background:#f0f0f0; } </style> .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; }   2- Create the view button (TargetControlID) as you know this contain the ID of the element that activates the modal popup: <asp:Button ID="btnView" runat="server" Text="View" /> .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;

$get('<%=txtName.ClientID%>').focus();   });   $find('ModalPopupExtender1').add_hiding(function() { alert('add_hiding event fires'); $get('<%=txtName.ClientID%>').value = ""; $get('<%=txtPassword.ClientID%>').value = "";   }); }   </script> .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;

  • What makes a Software Craftsman?

    - by Liam McLennan
    At the end of my visit to 8th Light Justin Martin was kind enough to give me a ride to the train station; for my train back to O’Hare. Just before he left he asked me an interesting question which I then posted to twitter: Liam McLennan: . @JustinMartinM asked what I think is the most important attributes of craftsmen. I said, "desire to learn and humility". What's yours? 6:25 AM Apr 17th via TweetDeck several people replied with excellent contributions: Alex Hung: @liammclennan I think kaizen sums up craftmanship pretty well, which is almost same as yours Steve Bohlen: @alexhung @liammclennan those are both all about saying "knowing what you don't know and not being afraid to go learn it" (and I agree!) Matt Roman: @liammclennan @JustinMartinM a tempered compulsion for constant improvement, and an awareness of what needs improving. Justin Martin: @mattroman @liammclennan a faculty for asking challenging questions, and a persistence to battle through difficult obstacles barring growth I thought this was an interesting conversation, and I would love to see other people contribute their opinions. My observation is that Alex, Steve, Matt and I seem to have essentially the same answer in different words. It is also interesting to note (as Alex pointed out) that these definitions are very similar to Alt.NET and the lean concept of kaizen.

    - by Justin
    Hey all, I'm trying to add a file upload control to my ASP.NET MVC 2 form but after I select a jpg and click Save, it gives the following error: The input is not a valid Base-64 string as it contains a non-base 64 character, more than two padding characters, or a non-white space character among the padding characters. Here's the view: <% using (Html.BeginForm("Save", "Developers", FormMethod.Post, new {enctype = "multipart/form-data"})) { %> <%: Html.ValidationSummary(true) %> <fieldset> <legend>Fields</legend> <div class="editor-label"> Login Name </div> <div class="editor-field"> <%: Html.TextBoxFor(model => model.LoginName) %> <%: Html.ValidationMessageFor(model => model.LoginName) %> </div> <div class="editor-label"> Password </div> <div class="editor-field"> <%: Html.Password("Password") %> <%: Html.ValidationMessageFor(model => model.Password) %> </div> <div class="editor-label"> First Name </div> <div class="editor-field"> <%: Html.TextBoxFor(model => model.FirstName) %> <%: Html.ValidationMessageFor(model => model.FirstName) %> </div> <div class="editor-label"> Last Name </div> <div class="editor-field"> <%: Html.TextBoxFor(model => model.LastName) %> <%: Html.ValidationMessageFor(model => model.LastName) %> </div> <div class="editor-label"> Photo </div> <div class="editor-field"> <input id="Photo" name="Photo" type="file" /> </div> <p> <%: Html.Hidden("DeveloperID") %> <%: Html.Hidden("CreateDate") %> <input type="submit" value="Save" /> </p> </fieldset> <% } %> And the controller: //POST: /Secure/Developers/Save/ [AcceptVerbs(HttpVerbs.Post)] public ActionResult Save(Developer developer) { //get profile photo. var upload = Request.Files["Photo"]; if (upload.ContentLength > 0) { string savedFileName = Path.Combine( ConfigurationManager.AppSettings["FileUploadDirectory"], "Developer_" + developer.FirstName + "_" + developer.LastName + ".jpg"); upload.SaveAs(savedFileName); } developer.UpdateDate = DateTime.Now; if (developer.DeveloperID == 0) {//inserting new developer. DataContext.DeveloperData.Insert(developer); } else {//attaching existing developer. DataContext.DeveloperData.Attach(developer); } //save changes. DataContext.SaveChanges(); //redirect to developer list. return RedirectToAction("Index"); } Thanks, Justin

  • Delphi 7 SOAP Authentication and SessionID HowTo

    - by Justin Philbrow
    Hello All, I am developing a 3 tier database application. 1.) MS SQL DB 2.) Middle tier SOAP Server (with Delphi 7) connected to the DB 3.) Clients (first win32 gui (with Delphi 7) - later other platfomrs) connected to the SOAP server I chose a SOAP Server to be open to various clients at a later stage (also some of the win32 gui clients will be stationed abroad - so the clients need to be thin) (this as suggested by Dr. Bob). I am new to SOAP and have been looking at different examples and papers about authentication. But cant quite get my head around it. I have made a SOAP server and client with Delphi's SOAP Server Application Wizard and added a SOAP SERVER Data Module, added a database connection and some datasets and providers. Connected the client with dbgrid etc and that part works fine. But I want the client first to login and then be able to access data and I want the server to log each connection and also when the client logs off or is disconnected, so I am guessing I need the sessionID and a timeout. I also want the server to be able to tell the clients who else is "connected" (or whos session is still active) at any given time. I have gathered that I need to make a authentication header, but cant figure out where or who I can get a sessionID. I presume that each time a client connectes to the server the server generates a sessionID? How do I get this? Any help or suggestions/pointer would be appreciated, thanks Justin OK take 2: OK, I have done the following so far (this is used from the example Bank Account SOAP application that comes with Delphi 7): procedure TForm1.btnLoginClick(Sender: TObject); var H: TAuthHeader; Headers: ISOAPHeaders; SoapData: IThorPayServerDB; begin SoapData := HTTPRIOOnForm as IThorPayServerDB; if not(SoapData.login(edtUser.Text,edtPassword.Text)) then begin showmessage('Not correct login'); exit; end; Headers := SoapData as ISoapHeaders; { Get the header from the incoming message } Headers.Get(TAuthHeader, TSoapHeader(H)); try if H < nil then begin FIdKey := H.IdNumber; FTimeStamp := H.TimeStamp; end else ShowMessage('No authentication header received from server'); finally H.Free; end; if FIdKey 0 then showmessage('Authenticated');; end; The SoapData.login returns the correct result, but for some reason I cant get hold of the header. In this case H is nil and the result becomes 'No authentication header received from server'. If I intersept the SOAP xml I can see that the header is there, here is the returned package: 1 1 4208687 2010-05-14T10:03:49.469+03:00 true Anyone any idea? In this case I am not using the SOAPConnetion that I am using for the DB, but a seperate HTTPTRIO component.

  • ASP.NET MVC 2 - Saving child entities on form submit

    - by Justin
    Hey, I'm using ASP.NET MVC 2 and am struggling with saving child entities. I have an existing Invoice entity (which I create on a separate form) and then I have a LogHours view that I'd like to use to save InvoiceLog's, which are child entities of Invoice. Here's the view: <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<TothSolutions.Data.Invoice>" %> <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"> Log Hours </asp:Content> <asp:Content ID="Content3" ContentPlaceHolderID="HeadContent" runat="server"> <script type="text/javascript"> $(document).ready(function () { $("#InvoiceLogs_0__Description").focus(); }); </script> </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <h2>Log Hours</h2> <% using (Html.BeginForm("SaveHours", "Invoices")) {%> <%: Html.ValidationSummary(true) %> <fieldset> <legend>Fields</legend> <table> <tr> <th>Date</th> <th>Description</th> <th>Hours</th> </tr> <% int index = 0; foreach (var log in Model.InvoiceLogs) { %> <tr> <td><%: log.LogDate.ToShortDateString() %></td> <td><%: Html.TextBox("InvoiceLogs[" + index + "].Description")%></td> <td><%: Html.TextBox("InvoiceLogs[" + index + "].Hours")%></td> <td>Hours</td> </tr> <% index++; } %> </table> <p> <%: Html.Hidden("InvoiceID") %> <%: Html.Hidden("CreateDate") %> <input type="submit" value="Save" /> </p> </fieldset> <% } %> <div> <%: Html.ActionLink("Back to List", "Index") %> </div> </asp:Content> And here's the controller code: //GET: /Secure/Invoices/LogHours/ public ActionResult LogHours(int id) { var invoice = DataContext.InvoiceData.Get(id); if (invoice == null) { throw new Exception("Invoice not found with id: " + id); } return View(invoice); } //POST: /Secure/Invoices/SaveHours/ [AcceptVerbs(HttpVerbs.Post)] public ActionResult SaveHours([Bind(Exclude = "InvoiceLogs")]Invoice invoice) { TryUpdateModel(invoice.InvoiceLogs, "InvoiceLogs"); invoice.UpdateDate = DateTime.Now; invoice.DeveloperID = DeveloperID; //attaching existing invoice. DataContext.InvoiceData.Attach(invoice); //save changes. DataContext.SaveChanges(); //redirect to invoice list. return RedirectToAction("Index"); } And the data access code: public static void Attach(Invoice invoice) { var i = new Invoice { InvoiceID = invoice.InvoiceID }; db.Invoices.Attach(i); db.Invoices.ApplyCurrentValues(invoice); } In the SaveHours action, it properly sets the values of the InvoiceLog entities after I call TryUpdateModel but when it does SaveChanges it doesn't update the database with the new values. Also, if you manually update the values of the InvoiceLog entries in the database and then go to this page it doesn't populate the textboxes so it's clearly not binding correctly. Thanks, Justin

  • Plan Operator Tuesday round-up

    - by Rob Farley
    Eighteen posts for T-SQL Tuesday #43 this month, discussing Plan Operators. I put them together and made the following clickable plan. It’s 1000px wide, so I hope you have a monitor wide enough. Let me explain this plan for you (people’s names are the links to the articles on their blogs – the same links as in the plan above). It was clearly a SELECT statement. Wayne Sheffield (@dbawayne) wrote about that, so we start with a SELECT physical operator, leveraging the logical operator Wayne Sheffield. The SELECT operator calls the Paul White operator, discussed by Jason Brimhall (@sqlrnnr) in his post. The Paul White operator is quite remarkable, and can consume three streams of data. Let’s look at those streams. The first pulls data from a Table Scan – Boris Hristov (@borishristov)’s post – using parallel threads (Bradley Ball – @sqlballs) that pull the data eagerly through a Table Spool (Oliver Asmus – @oliverasmus). A scalar operation is also performed on it, thanks to Jeffrey Verheul (@devjef)’s Compute Scalar operator. The second stream of data applies Evil (I figured that must mean a procedural TVF, but could’ve been anything), courtesy of Jason Strate (@stratesql). It performs this Evil on the merging of parallel streams (Steve Jones – @way0utwest), which suck data out of a Switch (Paul White – @sql_kiwi). This Switch operator is consuming data from up to four lookups, thanks to Kalen Delaney (@sqlqueen), Rick Krueger (@dataogre), Mickey Stuewe (@sqlmickey) and Kathi Kellenberger (@auntkathi). Unfortunately Kathi’s name is a bit long and has been truncated, just like in real plans. The last stream performs a join of two others via a Nested Loop (Matan Yungman – @matanyungman). One pulls data from a Spool (my post – @rob_farley) populated from a Table Scan (Jon Morisi). The other applies a catchall operator (the catchall is because Tamera Clark (@tameraclark) didn’t specify any particular operator, and a catchall is what gets shown when SSMS doesn’t know what to show. Surprisingly, it’s showing the yellow one, which is about cursors. Hopefully that’s not what Tamera planned, but anyway...) to the output from an Index Seek operator (Sebastian Meine – @sqlity). Lastly, I think everyone put in 110% effort, so that’s what all the operators cost. That didn’t leave anything for me, unfortunately, but that’s okay. Also, because he decided to use the Paul White operator, Jason Brimhall gets 0%, and his 110% was given to Paul’s Switch operator post. I hope you’ve enjoyed this T-SQL Tuesday, and have learned something extra about Plan Operators. Keep your eye out for next month’s one by watching the Twitter Hashtag #tsql2sday, and why not contribute a post to the party? Big thanks to Adam Machanic as usual for starting all this. @rob_farley
