  • how to monitor the program code execution? (file creation and modification by code lines etc)

    - by infant programmer
    My program is about triggering XSL transformation, Its fact that this code for carrying out the transformation, creates some dll and tmp files and deletes them pretty soon after the transformation is completed. It is almost untraceable for me to monitor the creation and deletion of files manually, so I want to include some chunk of codelines to display "which codeline has created/modified which tmp and dll files" in console window. This is the relevant part of the code: string strXmlQueryTransformPath = @"input.xsl"; string strXmlOutput = string.Empty; StringReader srXmlInput = null; StringWriter swXmlOutput = null; XslCompiledTransform xslTransform = null; XPathDocument xpathXmlOrig = null; XsltSettings xslSettings = null; MemoryStream objMemoryStream = null; objMemoryStream = new MemoryStream(); xslTransform = new XslCompiledTransform(false); xpathXmlOrig = new XPathDocument("input.xml"); xslSettings = new XsltSettings(); xslSettings.EnableScript = true; xslTransform.Load(strXmlQueryTransformPath, xslSettings, new XmlUrlResolver()); xslTransform.Transform(xpathXmlOrig, null, objMemoryStream); objMemoryStream.Position = 0; StreamReader objStreamReader = new StreamReader(objMemoryStream); strXmlOutput = objStreamReader.ReadToEnd(); // make use of Data in string "strXmlOutput" google and msdn search couldn't help me much..

  • Div at bottom of window and adaptable height div

    - by Rob
    Is there a way to get a div to always be at the bottom of the window, and another div to change its height to fill any space that it leaves, and that div will scroll if its content is too long. (I never want the window to scroll). This is best illustrated by a picture: The green div will always put itself at the bottom of the window, and the orange div will fill the gap. When the window is smaller, like in the right hand image, the orange div will be smaller and will scroll. The green div can be toggled. Sometimes the green div will have display: none, and then the orange div will stretch to the bottom. When the green div has display: block again, it will look like the picture again. It has to work in IE6. So far I can get the green div to go to the bottom by: position: absolute; bottom: 0; But I don't know how to get the orange div to do what I want.

  • IE7: container of hidden Div displays incorrectly

    - by dmr
    There is a search box div that contains a boxhead div and a boxbody div. Inside the boxbody div, there is a searchToggle div. When the user clicks a certain link on the page, the display style property of the searchToggle div is toggled between block and none. The 2 background-images for the body of the search box are set via the css of the searchBox div and the boxbody div. In IE7, when the searchToggle div is hidden, the background-image from the searchBox div extends on the left more than it should. It shows up correctly when the display of the searchToggle div is block. Everything show up correctly, in both cases in IE8 and FF. Any ideas why this is happening? The relevant HTML: <div class="searchBox"> <div class="boxhead"> <h2></h2> </div> <div class="boxbody"> <div id="searchToggle" name="searchToggle"> </div> </div> </div> The relevant CSS: .searchBox { margin: 0 auto; width: 700px; background: url(/images/myImageRight-r.gif) no-repeat bottom right; font-size: 100%; text-align: left; overflow: hidden; } .boxbody { margin: 0; padding: 5px 30px 31px; background-image: url(/images/myImageLeft.gif); background-repeat: no-repeat; background-position: left bottom; }

  • Floated element not included in parent, causing margin-bottom problems

    - by Christian Mann
    Right, so I've got a section of a page: <div class="article"> <div class="author"> <img src="images/officers/john_q_public_thm.jpg" /> <span class="name">John Q. Public</span> <span class="position">President</span> </div> <abbr class="postdate"> <span class="month m-01">Jan</span> <span class="day d-31">31</span> <span class="year y-2009">2009</span> </abbr> <div class="content"> <h2 class="title">Article Title</h2> <p>Pellentesque habitant morbi...facilisis luctus, metus</p> <p>Pellentesque habitant morbi...facilisis luctus, metus</p> </div> </div> <div class="article">...</div> <div class="article">...</div> The author and abbr divs are floated to the left. Each one of these article divs needs to be separated from its siblings by 5px or so. However, the author div is extending beyond the technical "height" of the div. The margin-bottom is doing nothing, as the space is being taken up by the floated author. This is somewhat difficult to envision, so I've placed it on my web server Is there any way to force the parent to be at least as tall as all of the floated elements within? If anyone figures out what I'm saying, thanks.

  • Experience with Take home Programming Test for Interviews

    - by Alan
    Okay this is not "programming" related per-se, but it is a situation that I believe the SO audience would be more familiar with, than say an ask.yahoo.com audience, so please forgive me. I had a phone screen the other day with a company that I really want to work for. It went pretty well, based on cues from the HR person, such as "Next step we're going to send you a programming test," and "Well, before I get ahead of myself, do you want to continue the interviewing process." and "We'll send out the test later this afternoon. It doesn't sound like you'll have trouble with it, but I want to be honest we do have a high failure rate on it." The questions asked weren't technical, just going down my resume, and talking about the work I've done, and how it relates to the position. Nothing I couldn't talk through. This was last Thursday. It's now Tuesday, and haven't received the test yet. I sent a follow up email yesterday to the lady who interviewed me, but haven't gotten a response. Anyone had a similar experience? Am I reading too much into this? Or was I off the mark by thinking I had moved on to the next step in the interview process. Since this is a company I really want to work for, I'm driving myself insane enumerating all the various what-if scenarios.

  • AJAX AutoCompletExtender doesn't allow to move ahead of first item with arrow-key

Thanks $(document).ready(function() { $('.form_sub').hide(); $('.theader').addClass('active'); $('.theader_t').click(function() { $('.form_header').show(); $('.form_sub').hide(); $('.theader').addClass('active'); $('.sub_theader').removeClass('active'); }); $('.sub_theader_t').click(function() { $('.form_header').hide(); $('.form_sub').show(); $('.theader').removeClass('active'); $('.sub_theader').addClass('active'); }); $('.top_head_img').click(function() { $(this).css({ position: 'relative', bottom: '20px' }).siblings().css( 'bottom', '0' ); }); }); <ul class="top_head"> <li> <a href="javascript:void(0)" onClick="selectPic5('top');"><img src="custom/images/top2.jpg" alt="Left" border="0" class="top_head_img"/></a> </li> <li> <a href="javascript:void(0)" onClick="selectPic5('center');"><img src="custom/images/mid2.jpg" alt="Center" border="0" class="top_head_img"/></a> </li> <li> <a href="javascript:void(0)" onClick="selectPic5('bottom');"><img src="custom/images/bot2.jpg" alt="Right" border="0" class="top_head_img"/></a> </li> </ul>

  • calculate camera up vector after glulookat()?

    - by carrots
    I'm just starting out teaching myself openGL and now adding openAL to the mix. I have some planets scattered around in 3D space and when I touch the screen, I'm assigning a sound to a random planet and then slowly and smoothly flying the "camera" over to look at it and listen to it. The animation/tweening part is working perfectly, but the openAL piece isn't quiet right. I move the camera around by doing a tiny translate() and gluLookAt() for every frame to keep things smooth (tweening the camera position and lookAt coords). The trouble seems to be with the stereo image I'm getting out of the headphones.. it seems like the left/right/up/down is mixed up sometimes after the camera rolls or spins. I am pretty sure the trouble is here: ALfloat listenerPos[]={camera->currentX,camera->currentY,camera->currentZ}; ALfloat listenerOri[]={camera->currentLookX, camera->currentLookY, camera->currentLookZ, 0.0,//Camera Up X <--- here 0.1,//Camera Up Y <--- here 0.0}//Camera Up Z <--- and here alListenerfv(AL_POSITION,listenerPos); alListenerfv(AL_ORIENTATION,listenerOri); I'm thinking I need to recompute the UP vector for the camera after each gluLookAt() to straighten out the audio positioning problem.. but after hours of googling and experimenting I'm stuck in math that suddenly got way over my head. 1) Am I right that I need to recalculate the up vector after each gluLookAt() i do? 2) If so, can someone please walk me though figuring out how to do that?

  • mimic a table using css

    - by user357523
    I'm trying to display a grid of items, with each item having a photo on the left and a description on the right, something like this: ---------------------------- | photo | item description | ---------------------------- I want to display these items in a 3x3 grid on the page. I have the grid part worked out, what I'm having trouble with is alignment of the photo and description. When the height of the description exceeds the height of the photo, I don't want the text to wrap under the photo. I essentially want to maintain two separate columns. I have tried this: .item{ padding-left: 60px; // size of photo + 5px margin background-position: 5px 0px; } <div class="item" style="background-image: url('/img/photo123.jpg');"> Here is the item description </div> That has worked very well. the markup is clean and I don't have to mess around with absolute/relative, however, now I can't add a border to the image. Can anyone suggest a workaround or alternative?

  • Interchange xsd and xsi in the output of XmlSerializer

    - by Sri Kumar
    XmlSerializer serializer = new XmlSerializer(typeof(IxComment)); System.IO.StringWriter aStream = new System.IO.StringWriter(); serializer.Serialize(aStream,Comments); commentsString = aStream.ToString(); Here the commentsString has the the following element in it <IxComment xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> Is there any possibility to interchange the xsi and xsd attribute and get the element as shown below <IxComment xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" > Will this cause any other issue? EDIT: Why do i need to do this? We are migrating an existing application from 1.1 to 3.0 and in the code there is a if loop int iStartTagIndex = strXMLString.IndexOf("<IxComment xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\">"); that check for the index of the IxComment. Here the o/p of the serializer and the condition differ in the position of xsd and xsi. So i am trying to know whether we can instruct the serializer to provided the o/p as required. I have another question here as this was an existing application does the serializer O/P differs with versions?

  • Median calculation in ActionScript 3

    - by Gabor Kako
    I have a number array and I'd like to calculate the median. When the array is odd, the calculation is OK, when it's even strange number comes up. private var numbers:String = "2,5,3,4,6,1"; private var array:Array = numbers.split(","); private function getMedian(array:Array):Number { var sortnums:Array = array.sort(Array.NUMERIC); var length:Number = sortnums.length; var mid1:Number; var mid2:Number; var median:Number; if(length % 2 == 0){ mid1 = length / 2; trace("mid1: "+mid1); mid2= ((length - 1) / 2)-0.5; trace("mid2: "+mid2); trace ("mid1: "+sortnums[mid1]+", mid2: "+sortnums[mid2]); median = (sortnums[mid1] + sortnums[mid2]) / 2; }else{ mid1 = (length / 2)-0.5 median = sortnums[mid1] } trace (median); return median; } The result is 21.5, but should be 3.5 mid1 and mid2 are a position in the array. Could somebody help?

  • Google maps KM bounds box reapplying itself on map zoom

    - by creminsn
    I have a map in which I apply a custom overlay using KMbox overlay to signify where I think the users general point of interest lies. What I want is to display this map to the user and allow them to click on the map to give me an exact location match of their POI. This all works fine except for when the user clicks on the map and changes the zoom of the map. Here's my code to add the marker to the map. function addMarker(location) { if(KmOverlay) { KmOverlay.remove(); } if(last_marker) { last_marker.setMap(null); } marker = new google.maps.Marker({ position: location, map: map }); // Keep track for future unsetting... last_marker = marker; } And to show the map I have this function. function show_map(lt, ln, zoom, controls, marker) { var ltln = new google.maps.LatLng(lt, ln); var vars = { zoom: zoom, center: ltln, mapTypeId: google.maps.MapTypeId.ROADMAP, navigationControl: controls, navigationControlOptions: {style: google.maps.NavigationControlStyle.ZOOM_PAN} , mapTypeControl: false, scaleControl: false, scrollwheel: false }; map = new google.maps.Map(document.getElementById("map_canvas"), vars); KmOverlay = new KmBox(map, new google.maps.LatLng(lat, lon), KmOpts); var totalBounds = new google.maps.LatLngBounds(); totalBounds.union(KmOverlay.getBounds()); google.maps.event.addListener(map, 'click', function(event) { addMarker(event.latLng); }); } I have a working example at the following link here

  • CSS to create curved corner between two elements?

    - by Tauren
    My UI has an unordered list on the left. When a list item is selected, a div appears on the right of it. I'd like to have a curved outer corner where the <li> and the <div> meet. See the white arrow in the image below. To extend the blue <li> to the edge of the <ul>, I'm planning to do something like this: li { right-margin: 2em; border-radius: 8px; } li.active { right-margin: 0; border-bottom-right-radius: 0; border-top-right-radius: 0; } Is there a better way to extend the <li> to the edge of the <ul>? Obviously, I'll include the webkit and mozilla border radius CSS as well. The main thing I'm unsure about is that outer corner underneath the bottom right corner of the active <li>. I have some ideas, but they seem like hacks. Any suggestions? NOTE that the <ul> is indicated in grey, but it would be white in the real design. Also, I'm planning to use Javascript to position the <div> correctly when an <li> is selected.

  • No GPS Update retrieved? Problem in Code?

    Hello mates, I've got a serious problem with my GPS on my Nexus One: I wrote a kind of hello world with GPS, but the Toast that should be displayed isn't :( I don't know what I'm doing wrong...maybe you could help me getting this work. Here's my code: package gps.test; import android.app.Activity; import android.content.Context; import android.location.Location; import android.location.LocationListener; import android.location.LocationManager; import android.os.Bundle; import android.widget.Toast; public class GPS extends Activity { private LocationManager lm; private LocationListener locationListener; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); // ---use the LocationManager class to obtain GPS locations--- lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE); locationListener = new MyLocationListener(); lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 100, 1, locationListener); } private class MyLocationListener implements LocationListener { @Override public void onLocationChanged(Location loc) { if (loc != null) { Toast.makeText( getBaseContext(), "Location changed : Lat: " + loc.getLatitude() + " Lng: " + loc.getLongitude(), Toast.LENGTH_SHORT).show(); } } @Override public void onProviderDisabled(String provider) { // TODO Auto-generated method stub } @Override public void onProviderEnabled(String provider) { // TODO Auto-generated method stub } @Override public void onStatusChanged(String provider, int status, Bundle extras) { // TODO Auto-generated method stub } } } Theoretically there should be a new toast every 100 milliseconds, shouldn't it? Or at least, when I change my position by one meter!? I've no idea why it doesn't. I must admit I'm new to the topic, maybe I've missed something? It would be great if you could give me a hint :) nice greetings, poeschlorn

  • C# Dataset Dynamically Add DataColumn

    - by Wesley
    I am trying to add a extra column to a dataset after a query has completed. I have a database relationship of the following: Employees / \ Groups EmployeeGroups Empoyees holds all the data for that individual, I'll name the unique key the UserID. Groups holds all the groups that a employee can be a part of, i.e. Super User, Admin, User; etc. I will name the unique key GroupID EmployeeGroups holds all the associations of which groups each employee belongs too. (UserID | GroupID) What I am trying to accomplish is after querying for a all users I want to loop though each user and add what groups that user is a part of by adding a new column to the dataset named 'Groups' which is a string to insert the values of the next query to get all the groups that user is a part of. Then by user of databinding populate a listview with all employees and their group associations My code is as follows; Position 5 is the new column I am trying to add to the dataset. string theQuery = "select UserID, FirstName, LastName, EmployeeID, Active from Employees"; DataSet theEmployeeSet = itsDatabase.runQuery(theQuery); DataColumn theCol = new DataColumn("Groups", typeof(string)); theEmployeeSet.Tables[0].Columns.Add(theCol); foreach (DataRow theRow in theEmployeeSet.Tables[0].Rows) { theRow.ItemArray[5] = "1234"; } At the moment, the code will create the new column but when i assign the data to that column nothing will be assigned, what am I missing? If there is any further explination or information I can provide, please let me know. Thank you all

  • Texture2D.Bounds.Intersect, but the Bounds never move? - XNA, .Net 4.0

    - by Gineer
    Hi all, I am still shiny new to XNA, so please forgive any stupid question and statements in this post (The added issue is that I am using Visual Studio 2010 with .Net 4.0 which also means very few examples exist out on the web - well, none that I could find easily): I have two 2D objects in a "game" that I am using to learn more about XNA. I need to figure out when these two objects intersect. I noticed that the Texture2D objects has a property named "Bounds" which in turn has a method named "Intersects" which takes a Rectangle (the other Texture2D.Bounds) as an argument. However when you run the code, the objects always intersect even if they are on separate sides of the screen. When I step into the code, I noticed that for the Texture2D Bounds I get 4 parameters back when you mouse over the Bounds and the X, and Y coordinates always read "X = 0, Y = 0" for both objects (hence they always intersect). The thing that confuses me is the fact that the Bounds property is on the Texture rather than on the Position (or Vector2) of the objects. I eventually created a little helper method that takes in the objects and there positions and then calculate whether they intersect, but I'm sure there must be a better way. any suggestions, pointers would be much appreciated.

  • Box2D in Flash runs quicker when drawing debug data than not

    - by bowdengm
    I've created a small game with Box2d for AS3 - I have sprites attached to the stage that take their position from the underlying Box2d world. These sprites are mostly PNGs. When the game runs with DrawDebugData() bening called every update, it runs nice and smoothly. However when I comment this out, it runs choppily. In both cases all my sprites are being rendered. So it seems that it's running faster when it's drawing the debug data additionaly (i.e. my sprites are on the screen in both cases!) What's going on? Does drawing the debug data flick some sort of 'render quick' switch? If so, what's the switch!? I can't see it in the Box2D code. function Update(e){ m_world.Step(m_timeStep, m_velocityIterations, m_positionIterations); // draw debug? m_world.DrawDebugData(); // with the above line in, I get 27fps, without it, I get 19fps. // that's the only change that's causing such a huge difference. doStuff(); } Interestingly, If i set the debug draw scale to something different to my world scale, it slows down to 19fps. So there's something happening when it draws the boxes under my sprites causing it to run quicker.. Cheers, Guy

  • jQuery replacement for javascript confirm

    - by dcp
    Let's say I want to prompt the user before allowing them to save a record. So let's assume I have the following button defined in the markup: <asp:Button ID="btnSave" runat="server" OnClick="btnSave_Click"></asp:Button> To force a prompt with normal javascript, I could wire the OnClick event for my save button to be something like this (I could do this in Page_Load): btnSave.Attributes.Add("onclick", "return confirm('are you sure you want to save?');"); The confirm call will block until the user actually presses on of the Yes/No buttons, which is the behavior I want. For the jquery dialog that is the equivalent, I tried something like this (see below). But the problem is that unlike javascript confirm(), it's going to get all the way through this function (displayYesNoAlert) and then proceed into my btnSave_OnClick method on the C# side. I need a way to make it "block", until the user presses the Yes or No button, and then return true or false so the btnSave_OnClick will be called or not called depending on the user's answer. Currently, I just gave up and went with javascript's confirm, I just wondered if there was a way to do it. function displayYesNoAlert(msg, closeFunction) { dialogResult = false; // create the dialog if it hasn't been instantiated if (!$("#dialog-modal").dialog('isOpen') !== true) { // add a div to the DOM that will store our message $("<div id=\"dialog-modal\" style='text-align: left;' title='Alert!'>").appendTo("body"); $("#dialog-modal").html(msg).dialog({ resizable: true, modal: true, position: [300, 200], buttons: { 'Yes': function () { dialogResult = true; $(this).dialog("close"); }, 'No': function () { dialogResult = false; $(this).dialog("close"); } }, close: function () { if (closeFunction !== undefined) { closeFunction(); } } }); } $("#dialog-modal").html(msg).dialog('open'); }

  • Google Maps API v3 - infoWindows all have same content

    - by paulriedel
    Hello, I've been having problems with the infoWindows and Google Maps API v3. Initially, I've ran into the problem that everyone else has of closing infoWindows when opening a new one. I thought to have solved the problem by defining "infowindow" beforehand. Now they close when I click on a new marker, but the content is the same. How should I re-structure my code to make sure the content is the right one each time - and only one infoWindow is open at a given time? Thank you! Paul var allLatLngs = new Array(); var last = 0; var infowindow; function displayResults(start, count){ if(start === undefined){ start = last; } if(count === undefined){ count = 20; } jQuery.each(jsresults, function(index, value) { if(index >= start && index < start+count){ var obj = jQuery.parseJSON(value); $("#textresults").append(index + ": <strong>" + obj.name + "</strong> " + Math.round(obj.distanz*100)/100 + " km entfernt" + "<br/>"); var myLatlng = new google.maps.LatLng(obj.geo_lat, obj.geo_lon); allLatLngs.push(myLatlng); var contentString = '<strong>'+obj.name+'</strong>'; infowindow = new google.maps.InfoWindow({ content: contentString }); var marker = new google.maps.Marker({ position: myLatlng, //title:"Hello World!" }); marker.setMap(map); google.maps.event.addListener(marker, 'click', function() { if (infowindow) { infowindow.close(map,marker); } infowindow.open(map,marker); }); } }); last = start+count;

  • How might one cope with the ambiguous value produced by GetDllDirectory?

    - by Integer Poet
    GetDllDirectory produces an ambiguous value. When the string this call produces is empty, it means one of the following: nobody has called SetDllDirectory somebody passed NULL to SetDllDirectory somebody passed an empty string to SetDllDirectory The first two cases are equivalent for my purposes, but the third case is a problem. If I want to write save/restore code (call GetDllDirectory to save the "old" value, SetDllDirectory to set a "new" value temporarily, and later SetDllDirectory again to restore the "old" value), I run the risk of reversing some other programmer's intent. If the other programmer intended for the current working directory to be in the DLL search order (in other words, one of the first two bullets is true), and I pass an empty string to SetDllDirectory, I will be taking the current working directory out of the DLL search order, reversing the other programmer's intent. Can anyone suggest an approach to eliminate or work around this ambiguity? P.S. I know having the current working directory in the DLL search order could be interpreted as a security hole. Nevertheless, it is the default behavior, and my code is not in a position to undo that; my code needs to be compatible with the expectations of all potential callers, many of which are large and old and beyond my control.
