    - by adhitya kristanto
    I tried to make jar with code from How to use JarOutputStream to create a JAR file? but that code always makes new parent folder of my input file/folder before it's inserted into .jar Folder's Path that I want to be added into jar: C:/Trial/MyFolder Folder that I want in MyJar.jar: MyFolder But Folder that was inserted in MyJar.jar: Trial Has it to be done that way?

  • Unit Testing VS 2008 Using Excel

    - by David
    When using Excel (2003) to provide data for my unit tests it seems to think that when a cell has TRUE / FALSE value that it is null when there has been no preceding cell values e.g. if (TestContext.DataRow["SatisfactionExtremelySatisfied"] != DBNull.Value) model.SatisfactionExtremelySatisfied = (bool)TestContext.DataRow ["SatisfactionExtremelySatisfied"]; Sample Excel Data DataRow SatisfactionExtremelySatisfied 0 1 2 TRUE 3 TRUE When reading the test data using OLEDB the cells with TRUE hold no value but when the preceding cells have the value FALSE entered it correctly gets the values TRUE. Am I missing something?

Is this because we are assigning it with alloc in //LINE 1? Also, why is //LINE 1 not: objStr = [NSMutableAttributedString* initWithString:@"(null)" attributes:attrDict] If I create a new string like (NSString*) str = [NSString initWithString:@"test"]; ... str = @"another string"; Would I have to release str, or is this wrong and if I do that I have to use [[NSString alloc] initWithString:@"test"]? Why isn't the pointer symbol used as in [[NSString* alloc] ...? Thanks

  • C++ Template const char array to int

    - by Levi Schuck
    So, I'm wishing to be able to have a static const compile time struct that holds some value based on a string by using templates. I only desire up to four characters. I know that the type of 'abcd' is int, and so is 'ab','abc', and although 'a' is of type char, it works out for a template<int v> struct What I wish to do is take sizes of 2,3,4,5 of some const char, "abcd" and have the same functionality as if they used 'abcd'. Note that I do not mean 1,2,3, or 4 because I expect the null terminator. cout << typeid("abcd").name() << endl; tells me that the type for this hard coded string is char const [5], which includes the null terminator on the end. I understand that I will need to twiddle the values as characters, so they are represented as an integer. I cannot use constexpr since VS10 does not support it (VS11 doesn't either..) So, for example with somewhere this template defined, and later the last line template <int v> struct something { static const int value = v; }; //Eventually in some method cout << typeid(something<'abcd'>::value).name() << endl; works just fine. I've tried template<char v[5]> struct something2 { static const int value = v[0]; } template<char const v[5]> struct something2 { static const int value = v[0]; } template<const char v[5]> struct something2 { static const int value = v[0]; } All of them build individually, though when I throw in my test, cout << typeid(something2<"abcd">::value).name() << endl; I get 'something2' : invalid expression as a template argument for 'v' 'something2' : use of class template requires template argument list Is this not feasible or am I misunderstanding something?

  • PHP problems when transfering code from Windows to OS X

    - by Makka95
    I have recently bought a new MacBook Pro. Before I had my MacBook Pro I was working on a website on my desktop computer. And now I want to transfer this code to my new MacBook Pro. The problem is that when I transfered the code (I put it on Dropbox and simply downloaded it on my MacBook Pro) I started to see lots of error messages in my PHP code. The error message I”m receiving is: Warning: Cannot modify header information - headers already sent by (output started at /some/file.php:1) in /some/file.php on line 23 I have done some research on this and it seems that this error is most frequently caused by a new line, simple whitespace or any output before the <?php sign. I have looked through all the places where I have cookies that are being sent in the HTTP request and also where I'm using the header() function. I haven’t detected any output or whitespace that possibly could interfere and cause this problem. Noteworthy is that the error always says that the output is started at line 1. Which got me thinking if there is some kind of coding differences in the way that the Mac OS X and Windows operating systems handle new lines or white spaces? Or could the Dropbox transfer messed something up? The code on one of the sites(login.php) which produces the error: <?php include "mysql_database.php"; login(); $id = $_SESSION['Loggedin']; setcookie("login", $id, (time()+60*60*24*30)); header('Location: ' . $_SERVER['HTTP_REFERER']); ?> login function: function login() { $connection = connecttodatabase(); $pass = ""; $user = ""; $query = ""; if (isset($_POST['user']) && $_POST['user'] != null) { $user = $_POST['user']; if (isset($_POST['pass']) && $_POST['pass'] != null) { $pass = md5($_POST['pass']); $query = "SELECT ID FROM Anvandare WHERE Nickname='$user' AND Password ='$pass'"; } } if ($query != "") { $id = $connection->query($query); $id = mysqli_fetch_assoc($id); $id = $id['ID']; $_SESSION['Loggedin'] = $id; } closeconnection($connection); } Complete error: Warning: Cannot modify header information - headers already sent by (output started at /Users/name/GitHub/website/login.php:1) in /Users/namn/GitHub/website/login.php on line 9

  • questions regarding the use of A* with the 15-square puzzle

    - by Cheeso
    I'm trying to build an A* solver for a 15-square puzzle. The goal is to re-arrange the tiles so that they appear in their natural positions. You can only slide one tile at a time. Each possible state of the puzzle is a node in the search graph. For the h(x) function, I am using an aggregate sum, across all tiles, of the tile's dislocation from the goal state. In the above image, the 5 is at location 0,0, and it belongs at location 1,0, therefore it contributes 1 to the h(x) function. The next tile is the 11, located at 0,1, and belongs at 2,2, therefore it contributes 3 to h(x). And so on. EDIT: I now understand this is what they call "Manhattan distance", or "taxicab distance". I have been using a step count for g(x). In my implementation, for any node in the state graph, g is just +1 from the prior node's g. To find successive nodes, I just examine where I can possibly move the "hole" in the puzzle. There are 3 neighbors for the puzzle state (aka node) that is displayed: the hole can move north, west, or east. My A* search sometimes converges to a solution in 20s, sometimes 180s, and sometimes doesn't converge at all (waited 10 mins or more). I think h is reasonable. I'm wondering if I've modeled g properly. In other words, is it possible that my A* function is reaching a node in the graph via a path that is not the shortest path? Maybe have I not waited long enough? Maybe 10 minutes is not long enough? For a fully random arrangement, (assuming no parity problems), What is the average number of permutations an A* solution will examine? (please show the math) I'm going to look for logic errors in my code, but in the meantime, Any tips? (ps: it's done in Javascript). Also, no, this isn't CompSci homework. It's just a personal exploration thing. I'm just trying to learn Javascript. EDIT: I've found that the run-time is highly depend upon the heuristic. I saw the 10x factor applied to the heuristic from the article someone mentioned, and it made me wonder - why 10x? Why linear? Because this is done in javascript, I could modify the code to dynamically update an html table with the node currently being considered. This allowd me to peek at the algorithm as it was progressing. With a regular taxicab distance heuristic, I watched as it failed to converge. There were 5's and 12's in the top row, and they kept hanging around. I'd see 1,2,3,4 creep into the top row, but then they'd drop out, and other numbers would move up there. What I was hoping to see was 1,2,3,4 sort of creeping up to the top, and then staying there. I thought to myself - this is not the way I solve this personally. Doing this manually, I solve the top row, then the 2ne row, then the 3rd and 4th rows sort of concurrently. So I tweaked the h(x) function to more heavily weight the higher rows and the "lefter" columns. The result was that the A* converged much more quickly. It now runs in 3 minutes instead of "indefinitely". With the "peek" I talked about, I can see the smaller numbers creep up to the higher rows and stay there. Not only does this seem like the right thing, it runs much faster. I'm in the process of trying a bunch of variations. It seems pretty clear that A* runtime is very sensitive to the heuristic. Currently the best heuristic I've found uses the summation of dislocation * ((4-i) + (4-j)) where i and j are the row and column, and dislocation is the taxicab distance. One interesting part of the result I got: with a particular heuristic I find a path very quickly, but it is obviously not the shortest path. I think this is because I am weighting the heuristic. In one case I got a path of 178 steps in 10s. My own manual effort produce a solution in 87 moves. (much more than 10s). More investigation warranted. So the result is I am seeing it converge must faster, and the path is definitely not the shortest. I have to think about this more. Code: var stop = false; function Astar(start, goal, callback) { // start and goal are nodes in the graph, represented by // an array of 16 ints. The goal is: [1,2,3,...14,15,0] // Zero represents the hole. // callback is a method to call when finished. This runs a long time, // therefore we need to use setTimeout() to break it up, to avoid // the browser warning like "Stop running this script?" // g is the actual distance traveled from initial node to current node. // h is the heuristic estimate of distance from current to goal. stop = false; start.g = start.dontgo = 0; // calcHeuristic inserts an .h member into the array calcHeuristicDistance(start); // start the stack with one element var closed = []; // set of nodes already evaluated. var open = [ start ]; // set of nodes to evaluate (start with initial node) var iteration = function() { if (open.length==0) { // no more nodes. Fail. callback(null); return; } var current = open.shift(); // get highest priority node // update the browser with a table representation of the // node being evaluated $("#solution").html(stateToString(current)); // check solution returns true if current == goal if (checkSolution(current,goal)) { // reconstructPath just records the position of the hole // through each node var path= reconstructPath(start,current); callback(path); return; } closed.push(current); // get the set of neighbors. This is 3 or fewer nodes. // (nextStates is optimized to NOT turn directly back on itself) var neighbors = nextStates(current, goal); for (var i=0; i<neighbors.length; i++) { var n = neighbors[i]; // skip this one if we've already visited it if (closed.containsNode(n)) continue; // .g, .h, and .previous get assigned implicitly when // calculating neighbors. n.g is nothing more than // current.g+1 ; // add to the open list if (!open.containsNode(n)) { // slot into the list, in priority order (minimum f first) open.priorityPush(n); n.previous = current; } } if (stop) { callback(null); return; } setTimeout(iteration, 1); }; // kick off the first iteration iteration(); return null; }

  • StreamWriter appends random data

    - by void
    Hi I'm seeing odd behaviour using the StreamWriter class writing extra data to a file using this code: public void WriteToCSV(string filename) { StreamWriter streamWriter = null; try { streamWriter = new StreamWriter(filename); Log.Info("Writing CSV report header information ... "); streamWriter.WriteLine("\"{0}\",\"{1}\",\"{2}\",\"{3}\"", ((int)CSVRecordType.Header).ToString("D2", CultureInfo.CurrentCulture), m_InputFilename, m_LoadStartDate, m_LoadEndDate); int recordCount = 0; if (SummarySection) { Log.Info("Writing CSV report summary section ... "); foreach (KeyValuePair<KeyValuePair<LoadStatus, string>, CategoryResult> categoryResult in m_DataLoadResult.DataLoadResults) { streamWriter.WriteLine("\"{0}\",\"{1}\",\"{2}\",\"{3}\"", ((int)CSVRecordType.Summary).ToString("D2", CultureInfo.CurrentCulture), categoryResult.Value.StatusString, categoryResult.Value.Count.ToString(CultureInfo.CurrentCulture), categoryResult.Value.Category); recordCount++; } } Log.Info("Writing CSV report cases section ... "); foreach (KeyValuePair<KeyValuePair<LoadStatus, string>, CategoryResult> categoryResult in m_DataLoadResult.DataLoadResults) { foreach (CaseLoadResult result in categoryResult.Value.CaseLoadResults) { if ((LoadStatus.Success == result.Status && SuccessCases) || (LoadStatus.Warnings == result.Status && WarningCases) || (LoadStatus.Failure == result.Status && FailureCases) || (LoadStatus.NotProcessed == result.Status && NotProcessedCases)) { streamWriter.Write("\"{0}\",\"{1}\",\"{2}\",\"{3}\",\"{4}\"", ((int)CSVRecordType.Result).ToString("D2", CultureInfo.CurrentCulture), result.Status, result.UniqueId, result.Category, result.ClassicReference); if (RawResponse) { streamWriter.Write(",\"{0}\"", result.ResponseXml); } streamWriter.WriteLine(); recordCount++; } } } streamWriter.WriteLine("\"{0}\",\"{1}\"", ((int)CSVRecordType.Count).ToString("D2", CultureInfo.CurrentCulture), recordCount); Log.Info("CSV report written to '{0}'", fileName); } catch (IOException execption) { string errorMessage = string.Format(CultureInfo.CurrentCulture, "Unable to write XML report to '{0}'", fileName); Log.Error(errorMessage); Log.Error(exception.Message); throw new MyException(errorMessage, exception); } finally { if (null != streamWriter) { streamWriter.Close(); } } } The file produced contains a set of records on each line 0 to N, for example: [Record Zero] [Record One] ... [Record N] However the file produced either contains nulls or incomplete records from further up the file appended to the end. For example: [Record Zero] [Record One] ... [Record N] [Lots of nulls] or [Record Zero] [Record One] ... [Record N] [Half complete records] This also happens in separate pieces of code that also use the StreamWriter class. Furthermore, the files produced all have sizes that are multiples of 1024. I've been unable to reproduce this behaviour on any other machine and have tried recreating the environment. Previous versions of the application didn't exhibite this behaviour despite having the same code for the methods in question. EDIT: Added extra code.

  • Incorrect string encodings

    - by James
    Note: I have read all of the related PHP, UTF-8, character encoding articles that are usually suggested, but my question relates to data inserted before I applied such techniques. I am wishing to retrospectively fix all character encoding problems. Now all connections are set as utf8 using PDO. PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES utf8' Unfortunately, a large amount of data was inserted that is of questionable encoding before I had implemented correct character encoding practices. As displayed by: $sql = "SELECT name FROM data LIMIT 3"; foreach ($pdo->query($sql) as $row) { $name = $row['name']; echo $name . "\n"; echo utf8_encode($name) . "\n"; echo utf8_decode($name) . "\n"; echo htmlspecialchars($name, ENT_QUOTES, 'UTF-8') . "\n"; echo htmlspecialchars(utf8_encode($name), ENT_QUOTES, 'UTF-8') . "\n"; echo htmlspecialchars(utf8_decode($name), ENT_QUOTES, 'UTF-8') . "\n"; echo '<hr/>'; } Which produces: Antonín Dvořák AntonÃÆín DvoÃâ¦Ãâ¢ÃÆák Anton??­n Dvo??????¡k Antonín Dvořák AntonÃÆín DvoÃâ¦Ãâ¢ÃÆák ---------- Ô±Ö€Õ¡Õ´ Ô½Õ¡Õ¹Õ¡Õ¿Ö€ÕµÕ¡Õ¶ ñÃâ¬Ã¡Ã´ ýáùáÿÃâ¬ÃµÃ¡Ã¶ ????? ??????????

Ô±ÖÕ¡Õ´ Ô½Õ¡Õ¹Õ¡Õ¿ÖÕµÕ¡Õ¶ ???? ????????? ???? ????????? Ô±ÖÕ¡Õ´ Ô½Õ¡Õ¹Õ¡Õ¿ÖÕµÕ¡Õ¶ ???? ????????? ---------- Tiësto Tiësto Ti?sto Tiësto Tiësto ---------- And here is a dump of the database rows concerned: DROP TABLE IF EXISTS `data`; CREATE TABLE IF NOT EXISTS `data` ( `id` int(10) unsigned NOT NULL AUTO_INCREMENT, `name` varchar(80) NOT NULL, PRIMARY KEY (`id`), KEY `name` (`name`(10)), ) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=0; INSERT INTO `data` (`id`, `name`) VALUES (0, 'Antonín Dvořák'), (1, 'Ô±Ö€Õ¡Õ´ Ô½Õ¡Õ¹Õ¡Õ¿Ö€ÕµÕ¡Õ¶'), (2, 'Tiësto'); The 3rd and 6th lines of the 3rd row "Tiësto" are then correctly echoed. I'm just unsure what is the best way to correct encodings/detect the encodings of bad strings and correct, etc.

  • Multiple Timers with setTimeInterval

    - by visibleinvisibly
    I am facing a problem with setInterval being used in a loop. I have a function subscribeFeed( ) which takes an array of urls as input. It loops through the url array and subscribes each url to getFeedAutomatically() using a setInterval function. so if three URL's are there in the array, then 3 setInterval's will be called. The problem is 1)how to distinguish which setInterval is called for which URL. 2)it is causing Runtime exception in setInterval( i guess because of closure problem in javascript) //constructor function myfeed(){ this.feedArray = []; } myfeed.prototype.constructor= myfeed; myfeed.prototype.subscribeFeed =function(feedUrl){ var i=0; var url; var count = 0; var _this = this; var feedInfo = { url : [], status : "" }; var urlinfo = []; feedUrl = (feedUrl instanceof Array) ? feedUrl : [feedUrl]; //notifyInterval = (notifyInterval instanceof Array) ? notifyInterval: [notifyInterval]; for (i = 0; i < feedUrl.length; i++) { urlinfo[i] = { url:'', notifyInterval:5000,// Default Notify/Refresh interval for the feed isenable:true, // true allows the feed to be fetched from the URL timerID: null, //default ID is null called : false, position : 0, getFeedAutomatically : function(url){ _this.getFeedUpdate(url); }, }; urlinfo[i].url = feedUrl[i].URL; //overide the default notify interval if(feedUrl[i].NotifyInterval /*&& (feedUrl[i] !=undefined)*/){ urlinfo[i].notifyInterval = feedUrl[i].NotifyInterval; } // Trigger the Feed registered event with the info about URL and status feedInfo.url[i] = feedUrl[i].URL; //Set the interval to get the feed. urlinfo[i].timerID = setInterval(function(){ urlinfo[i].getFeedAutomatically(urlinfo[i].url); }, urlinfo[i].notifyInterval); this.feedArray.push(urlinfo[i]); } } // The getFeedUpate function will make an Ajax request and coninue myfeed.prototype.getFeedUpdate = function( ){ } I am posting the same on jsfiddle http://jsfiddle.net/visibleinvisibly/S37Rj/ Thanking you in advance

  • 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; }

  • Calling CryptUIWizDigitalSign from .NET on x64

    - by Joe Kuemerle
    I am trying to digitally sign files using the CryptUIWizDigitalSign function from a .NET 2.0 application compiled to AnyCPU. The call works fine when running on x86 but fails on x64, it also works on an x64 OS when compiled to x86. Any idea on how to better marshall or call from x64? The Win32exception returned is "Error encountered during digital signing of the file ..." with a native error code of -2146762749. The relevant portion of the code are: [StructLayout(LayoutKind.Sequential)] public struct CRYPTUI_WIZ_DIGITAL_SIGN_INFO { public Int32 dwSize; public Int32 dwSubjectChoice; [MarshalAs(UnmanagedType.LPWStr)] public string pwszFileName; public Int32 dwSigningCertChoice; public IntPtr pSigningCertContext; [MarshalAs(UnmanagedType.LPWStr)] public string pwszTimestampURL; public Int32 dwAdditionalCertChoice; public IntPtr pSignExtInfo; } [DllImport("Cryptui.dll", CharSet=CharSet.Unicode, SetLastError=true)] public static extern bool CryptUIWizDigitalSign(int dwFlags, IntPtr hwndParent, string pwszWizardTitle, ref CRYPTUI_WIZ_DIGITAL_SIGN_INFO pDigitalSignInfo, ref IntPtr ppSignContext); CRYPTUI_WIZ_DIGITAL_SIGN_INFO digitalSignInfo = new CRYPTUI_WIZ_DIGITAL_SIGN_INFO(); digitalSignInfo = new CRYPTUI_WIZ_DIGITAL_SIGN_INFO(); digitalSignInfo.dwSize = Marshal.SizeOf(digitalSignInfo); digitalSignInfo.dwSubjectChoice = 1; digitalSignInfo.dwSigningCertChoice = 1; digitalSignInfo.pSigningCertContext = pSigningCertContext; digitalSignInfo.pwszTimestampURL = timestampUrl; digitalSignInfo.dwAdditionalCertChoice = 0; digitalSignInfo.pSignExtInfo = IntPtr.Zero; digitalSignInfo.pwszFileName = filepath; CryptUIWizDigitalSign(1, IntPtr.Zero, null, ref digitalSignInfo, ref pSignContext)); And here is how the SigningCertContext is retrieved (minus various error handling) public IntPtr GetCertContext(String pfxfilename, String pswd) IntPtr hMemStore = IntPtr.Zero; IntPtr hCertCntxt = IntPtr.Zero; IntPtr pProvInfo = IntPtr.Zero; uint provinfosize = 0; try { byte[] pfxdata = PfxUtility.GetFileBytes(pfxfilename); CRYPT_DATA_BLOB ppfx = new CRYPT_DATA_BLOB(); ppfx.cbData = pfxdata.Length; ppfx.pbData = Marshal.AllocHGlobal(pfxdata.Length); Marshal.Copy(pfxdata, 0, ppfx.pbData, pfxdata.Length); hMemStore = Win32.PFXImportCertStore(ref ppfx, pswd, CRYPT_USER_KEYSET); pswd = null; if (hMemStore != IntPtr.Zero) { Marshal.FreeHGlobal(ppfx.pbData); while ((hCertCntxt = Win32.CertEnumCertificatesInStore(hMemStore, hCertCntxt)) != IntPtr.Zero) { if (Win32.CertGetCertificateContextProperty(hCertCntxt, CERT_KEY_PROV_INFO_PROP_ID, IntPtr.Zero, ref provinfosize)) pProvInfo = Marshal.AllocHGlobal((int)provinfosize); else continue; if (Win32.CertGetCertificateContextProperty(hCertCntxt, CERT_KEY_PROV_INFO_PROP_ID, pProvInfo, ref provinfosize)) break; } } finally { if (pProvInfo != IntPtr.Zero) Marshal.FreeHGlobal(pProvInfo); if (hMemStore != IntPtr.Zero) Win32.CertCloseStore(hMemStore, 0); } return hCertCntxt; }

  • SharePoint List Service Recursive not working

    - by stranger001
    Hi, I am using the following code to retrieve the documents in a list. Its working fine. However, it only returns documents and folders in root of the doc library. Is there any thing wrong I am doing here? I am looking for files in sub folders with recursive mode. Service service = new Service(); service.setMaintainSession(true); call = (Call) service.createCall(); call.setTargetEndpointAddress( new java.net.URL("<host>/_vti_bin/lists.asmx") ); call.setOperationName(new QName("http://schemas.microsoft.com/sharepoint/soap/","GetListItems")); call.setProperty(Call.SOAPACTION_USE_PROPERTY, new Boolean("true")); call.setProperty(Call.SOAPACTION_URI_PROPERTY,"http://schemas.microsoft.com/sharepoint/soap/GetListItems"); call.addParameter(new javax.xml.namespace.QName("http://schemas.microsoft.com/sharepoint/soap/", "listName"), new javax.xml.namespace.QName("http://www.w3.org/2001/XMLSchema", "string"), java.lang.String.class, javax.xml.rpc.ParameterMode.IN); MessageElement me = new MessageElement(new QName("QueryOptions")); me.addChildElement(new MessageElement(new QName( "IncludeMandatoryColumns"))).addTextNode("true"); me.addChildElement(new MessageElement(new QName( "ViewAttributes"))).addAttribute(javax.xml.soap.SOAPFactory.newInstance().createName("Scope"), "Recursive"); MessageElement[] me1 = {me}; String strMyString = "" + "<Query>" + "<OrderBy><FieldRef Name=\"ows_Modified\" Ascending=\"TRUE\" /></OrderBy>" + "</Query>"; MessageElement[] meArray = { getMeFromString(strMyString) };// Array call.addParameter("query",org.apache.axis.Constants.XSD_SCHEMA, javax.xml.rpc.ParameterMode.IN); call.addParameter("queryOptions",org.apache.axis.Constants.XSD_SCHEMA, javax.xml.rpc.ParameterMode.IN); call.setReturnType(org.apache.axis.Constants.XSD_SCHEMA); Schema ret = (Schema)call.invoke(new Object[] {"listGUID",meArray, me1 }); public org.apache.axis.message.MessageElement getMeFromString(final String strMyString) { DocumentBuilder docBuilder = null; try { docBuilder = DocumentBuilderFactory.newInstance().newDocumentBuilder(); } catch (final ParserConfigurationException e) { e.printStackTrace(); } catch (final FactoryConfigurationError e) { e.printStackTrace(); } final StringReader reader = new StringReader(strMyString); final InputSource inputsource = new InputSource(reader); Document doc = null; try { doc = docBuilder.parse(inputsource); } catch (final SAXException e) { e.printStackTrace(); } catch (final IOException e) { e.printStackTrace(); } final Element ele = doc.getDocumentElement(); final MessageElement msg = new MessageElement(ele); return msg; }

  • Create thumbnail and reduce image size

    - by oo
    I have very large images (jpg) and i want to write a csharp program to loop through the files and reduce the size of each image by 75%. I tried this: Image thumbNail = image.GetThumbnailImage(800, 600, null, new IntPtr()); but the file size is still very large. Is there anyway to create thumbnails and have the filesize be much smaller?

    - by webgenius
    Why is it not possible to create an object of an abstract class? I understand that the compiler creates a VTABLE with VPTR pointing to NULL. Does this prevent from creating an object of an abstract class?

EventHandler<MyEventArgs> temp = SampleEvent; if (temp != null) temp(this, new MyEventArgs(val)); } I do not understand, "copy to temporary variable", isnt it reference type?
