727,269 | 0 | Web service response is null, but SOAP message response is valid <p>I am writing a web service starting with writing the WSDL. I have been generating server-side skeleton code using wsimport and then writing my own implementing class. I'm running the web service on an Axis2 server. When using soapUI, the SOAP messages coming to and from the service look fine, but when using a web service client, I'm getting null in the client-side stubs. I've heard that this could be a namespace issue, but I see anything wrong. Here is my copy of the WSDL. Any help would be appreciated.</p> <pre><code><?xml version="1.0" encoding="UTF-8"?> <wsdl:definitions xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:ns1="http://org.apache.axis2/xsd"

28,505,332 | 0 | <p>I have it working now. I have decided to change things around so the default css page loaded has the styles necessary for the newer model phones which support overflow:scroll. So therefore I have set the heights of the body, container_wrappper and side menu to 100% to begin with instead of changing that after receiving a positive response to checking if overflow: scroll is supported... Instead I check if overflow scroll is not supported and then if not supported i dynamically add a new stylesheet which has the heights of the body and container_wrapper as height: auto; instead of height:100%. it seems that this way around ie changing from height:100% to height: auto displays it correctly as opposed to the way i was doing it starting with no height and adding in height 100% if overflow scroll is* supported.. it was to do with the speed of things loading but when i do it this way even though there is a delay in loading the second stylesheet it still displays correctly after loading. so i add the following code to my head:</p> <pre><code><link rel="stylesheet" type="text/css" href="css/main_style_new_phones.css"/> <script> if(!canOverflowScroll()){ var lnk=document.createElement('link'); lnk.href='css/main_style_old_phones.css'; lnk.rel='stylesheet'; lnk.type='text/css'; (document.head||document.documentElement).appendChild(lnk); } </code></pre> <p>and this is the css in main_style_new_phones.css </p> <pre><code>body{ margin-top: 0px; /*moves #container right up to top of page so no gap*/ font-family:Arial,Helvetica,sans-serif; width: 100%; overflow: auto; z-index: 1; height: 100%; } #container_wrapper{ position: absolute; left: 0px; top: 0px; display: block; margin: 0 auto; width: 100%; background: #120F3A; overflow: auto; max-width: 100%; /*same width as full logo image width so that when on full screen the background color of the container doesn't spread across*/ z-index: 4; -webkit-transition: .3s; /* Android 2.1+, Chrome 1-25, iOS 3.2-6.1, Safari 3.2-6 */ -moz-transition: .3s; -o-transition: .3s; transition: .3s; /* Chrome 26, Firefox 16+, iOS 7+, IE 10+, Opera, Safari 6.1+ */ height: 100%; } #headernav { width: 100%; position:fixed; top: 0px; left: 0px; z-index: 10; background: #000; padding-bottom: 2px; -webkit-transition: .3s; /* Safari */ transition: .3s; } </code></pre> <p>and in the css for phones that do not support overflow scroll in main_style_old_phones.css:</p> <pre><code>body{ height: auto; } #container_wrapper{ height: auto; } #headernav { position:absolute; } #swipe_menu_right{ height: auto; } </code></pre> |

However, I do not know how wide the window will be and so I would like the text container to expand to fill the available space.</p> <p>I have tried simply putting vertical-align:middle on the text container. That kind of works, but the text will wrap below the image if the text is too long. In order to combat this, I used display:inline-block on the text container. However, this then puts the whole text container below the image!</p> <p>So far, I have something like this:</p> <pre><code><span><img src="img.gif" /></span> <span style="display:inline-block; vertical-align:middle">Text goes here</span> </code></pre> |

11,455,088 | 0 | <p>That code in the tutorial will work if you are adding new rows to a blank worksheet. Since you have a template that you are using that does have rows you will need to do a lot more work in order to add a row in the middle of your worksheet. You pretty much need to use the same code to add in the row, but then you have to manually update the row index of every row after the row you insert. You also have to update the merged cell references and the hyperlinks references as well. There might be more that you have to update, but I never had to update more than these three things. The main method to insert a row is below:</p> <pre><code> /// <summary> /// Inserts a new row at the desired index. If one already exists, then it is /// returned. If an insertRow is provided, then it is inserted into the desired /// rowIndex /// </summary> /// <param name="rowIndex">Row Index</param> /// <param name="worksheetPart">Worksheet Part</param> /// <param name="insertRow">Row to insert</param> /// <param name="isLastRow">Optional parameter - True, you can guarantee that this row is the last row (not replacing an existing last row) in the sheet to insert; false it is not</param> /// <returns>Inserted Row</returns> public static Row InsertRow(uint rowIndex, WorksheetPart worksheetPart, Row insertRow, bool isNewLastRow = false) { Worksheet worksheet = worksheetPart.Worksheet; SheetData sheetData = worksheet.GetFirstChild<SheetData>(); Row retRow = !isNewLastRow ? sheetData.Elements<Row>().FirstOrDefault(r => r.RowIndex == rowIndex) : null; // If the worksheet does not contain a row with the specified row index, insert one. if (retRow != null) { // if retRow is not null and we are inserting a new row, then move all existing rows down. if (insertRow != null) { UpdateRowIndexes(worksheetPart, rowIndex, false); UpdateMergedCellReferences(worksheetPart, rowIndex, false); UpdateHyperlinkReferences(worksheetPart, rowIndex, false); // actually insert the new row into the sheet retRow = sheetData.InsertBefore(insertRow, retRow); // at this point, retRow still points to the row that had the insert rowIndex string curIndex = retRow.RowIndex.ToString(); string newIndex = rowIndex.ToString(); foreach (Cell cell in retRow.Elements<Cell>()) { // Update the references for the rows cells. cell.CellReference = new StringValue(cell.CellReference.Value.Replace(curIndex, newIndex)); } // Update the row index. retRow.RowIndex = rowIndex; } } else { // Row doesn't exist yet, shifting not needed. // Rows must be in sequential order according to RowIndex. Determine where to insert the new row.

Prediction will be: </p> <pre><code>Price (1 item) = 0 + 20*1 + 50*0 + 100*0 = 20$ (thetas are assumed for example) Price (2 item) = 0 + 20*0 + 50*1 + 100*0 = 50$ </code></pre> <p><strong>Ordinal encoding for color:</strong> In this case all colors will have 1 common theta but my assigned multipliers (10, 20, 30) differ:</p> <pre><code>Price (1 item) = 0 + 20*10 = 200$ (theta assumed for example) Price (2 item) = 0 + 20*20 = 400$ (theta assumed for example) </code></pre> <p>In my model White < Red < Black in prices. Seem to be that correlation works correctly and it is logical predictions in both cases. For ordinal and categorical representations. So I can use any encoding for my regression regardless of the data type (categorical or ordinal)? This division in data representations is just a matter of conventions and software-oriented representations rather than a matter of regression logic itself?</p> |

31,256,206 | 0 | C++ memory alignment <p>So I read that when variables are declared in c++ if you want to get the optimum cache reads the memory should stick to its natural alignment. Example:</p> <pre><code>int a; // memory address should end in 0x0,0x4,0x8,0xC int b[2]; // 8 bytes 0x0,0x8 int b[4]; // 16 bytes 0x0 </code></pre> <p>But in practice these variables do not follow the "natural alignment" rules, a 16 byte variable was residing at a memory address that ended in 0xC. Why is this ?</p> |

23,340,283 | 0 | <p>Are you meaning that you want the text values of all checked checkboxes, or the text value of every checkbox, or...?</p> <p>Either way, you want to iterate through the Page's Controls collection to find all controls that have a type of Checkbox and then use that to get their text values (and you can limit whether you want to include checked boxes or not in that iteration). And, yes, using a List might be easier than starting with an array, because you can easily add to a List<> and then transform it into an array with little pain.</p> |
10,722,948 | 0 | <p>You could use background subtraction. This would involve having the empty car park image as your background and then doing a comparison of the changes between that and any subsequent images. If you are looking at car parking spaces then you would want to split the image up into sectors(car park spaces) and do the background subtraction per sector. However due to constant changes in lighting of the carpark as the sun moves you are going to run into issues where the background image will change due to shadows, brightness,etc. An approach to handle this is to do frame by frame comparisons and if it changes by a certain threshold then it is most likely a car has parked rather than the sun has moved as the car will cause a much higher amount of change in a short space of time than the effects of lighting will.</p> |

12,528,369 | 0 | node.js return to client waiting for event <p>I'm playing around a bit with the concept of Comet on node.js, but I'm still a bit confused and I'm wondering if anyone here can point me in the right direction.</p> <p>Think on a game app where client code should ask for it's turn to make a move (for example on a chess app). What I'm thinking here is in use something like this:</p> <p>When match starts a method on the node server is called to create an element on a matches array with the id of the match and the initial player.</p> <p>When a player makes a move a method is called to update the current player on the array element referencing this match. This method should fire an event when the change occurs.</p> <p>Before being able to make any move, client code should call a method on the server that checks if it's the turn of the user and that waits for the changing player event if wasn't it's turn.</p> <p>I'm not sure if this is a good approach within the event loop, and if it is I don't see how can I make the method to wait until event to return.</p> <p>Any suggestions?</p> |
