  • Processing image data in java me

    - by Trimack
    Hi, I want to process raw data from a picture taken in java me with byte[] snap = videoControl.getSnapshot(encoding); My question is, whether I should try working already with snap or should I first create the image from this array Image im = Image.createImage(snap, 0, snap.length); and then work with that? Or is there some better documentation of both methods, i.e. getSnapshot and createImage than the Java API reference?

  • Excel Automation - creating a new worksheet

    - by Andrew Shepherd
    I am attempting what seems like a simple task: using C# to create a new Excel document containing new worksheets. For some reason, I am getting a strange COM error (0x800A03EC) Has anyone managed to get this to work? Does anyone have suggestions as to how to troubleshoot this? I've isolated this into the minimum amount of code: using Microsoft.Office.Interop.Excel; using System.Diagnostics; namespace ExcelAutomation { public static class ExcelTests { public static void CreateWorksheet() { try { var app = new Microsoft.Office.Interop.Excel.Application(); app.Visible = true; var workBooks = app.Workbooks; var newWorkbook = app.Workbooks.Add(XlWBATemplate.xlWBATWorksheet); Worksheet existingWorksheet = (Worksheet)newWorkbook.Sheets[1]; Worksheet workSheet = (Worksheet)newWorkbook.Sheets.Add ( null, // before existingWorksheet, null, // 1, null //XlSheetType.xlWorksheet ); } catch (System.Runtime.InteropServices.COMException ex) { Trace.WriteLine(string.Format("Caught COMException. Message: \"{0}\"", ex.Message)); } } } } The output window now says: Caught COMException. Message: "Exception from HRESULT: 0x800A03EC"

  • Do I really need bindParam?

    - by sandelius
    Hi there! I'm trying to do a little PDO CRUD to learn some PDO. I have a question about bindParam. Here's my update method right now: public static function update($conditions = array(), $data = array(), $table = '') { self::instance(); // Late static bindings (PHP 5.3) $table = ($table === '') ? self::table() : $table; // Check which data array we want to use $values = (empty($data)) ? self::$_fields : $data; $sql = "UPDATE $table SET "; foreach ($values as $f => $v) { $sql .= "$f = ?, "; } // let's build the conditions self::build_conditions($conditions); // fix our WHERE, AND, OR, LIKE conditions $extra = self::$condition_string; // querystring $sql = rtrim($sql, ', ') . $extra; // let's merge the arrays into on $v_val = array_values($values); $c_val = array_values($conditions); $array = array_merge($v_val, self::$condition_array); $stmt = self::$db->prepare($sql); return $stmt->execute($array); } in my "self::$condition_array" I get all the right values from the ?. SO the query looks like this: UPDATE table SET this = ?, another = ? WHERE title = ? AND time = ? as you can see I dont use bindParams instead I pass the right values in the right order ($array) directly into the execute($array) method. This works like a charm BUT is it safe not use use bindParam here? If not then how can I do it? Thanks from Sweden Tobias

  • iPhone App is leaking memory; Instruments and Clang cannot find the leak

    - by Norbert
    Hi, i've developed an iPhone program which is kind of an image manipulation program: The user get an UIImagePickerController and selects an image. Then the program does some heavy calculating in a new thread (for responsiveness of the application). The thread has, of course, its own autorelease pool. When calculation is done, the seperated thread signals the main thread that the result can be presented. The app creates a new view controller, pushes it onto the navigation controller. In short: UIImagePickerController new thread (autorelease pool) does some heavy calculation with image data signal to main thread that it's done main thread creates view controller and pushes it onto navigation controller view controller presents image result My program works well, but if I dismiss the navigation controller's top view controller by tapping on the back button and repeat the whole process several times, my app crashes. But only on the device! Instruments cannot find any leaks (except for some minor ones which I don't feel responsible for: thread creation, NSCFString; overall about 10 kB). Even Clang static analyzer tells me that my could seems to be all right. I know that the UIImage class can cache images and objects returned from convenience methods get freed only whet their autorelease pool gets drained. But most of the time I work with CGImageRef and I use UIImage' alloc, init & release methods to free memory as soon as possible. Currently, I don't know how to isolate the problem. How would you approach this problem?

  • Need help coming up with a better HtmlHelper Extension method.

    - by zSysop
    Hi all, I've inherited the following code and i was wondering if i could pick at your brains to see if there's a nicer way to do duplicate this. Heres the html for most of our partial input views <% if (Html.IsInputReadOnly()) { %> <td> Id </td> <td> <%= Html.TextBox( "Id" , (Model == null ? null : Model.Id) , new { @readonly = "readonly", @disabled="disabled" } )%> <% } elseif (Html.IsInputDisplayable() == false) { %> <td></td> <td></td> <% } else { %> <td>Id</td> <td><%= Html.TextBox("Id")%> <%= Html.ValidationMessage("Id", "*")%> </td> <%} %> Here are my entension methods public static bool IsInputReadOnly(this HtmlHelper helper) { string actionName = ActionName(helper); // The Textbox should be read only on all pages except for the lookup page if (actionName.ToUpper().CompareTo("EDIT") == 0) return true; return false; } public static bool IsInputDisplayable(this HtmlHelper helper) { string actionName = ActionName(helper); // The Textbox should be read only on all pages except for the lookup page if (actionName.ToUpper().CompareTo("CREATE") == 0) return true; return false; } Thanks in advance

  • How do I tell ReSharper that an attribute means that a method is used?

    - by Roger Lipscombe
    I'm playing with SpecFlow, and ReSharper thinks that my step definitions are unused (I guess because they're used via reflection): [Binding] public class StepDefinitions { // ... [When(@"I press add")] public void WhenIPressAdd() // R# thinks this is unused { _calculator.PressAdd(); } // ... } How can I tell ReSharper that methods with [Given], [When], [Then] attributes (etc.) are actually used? I don't want to use // ReSharper disable UnusedMember.Global comments.

  • Reimplementing data structures in the real world

    - by Jason
    The topic of algorithms class today was reimplementing data structures, specifically ArrayList in Java. The fact that you can customize a structure for in various ways definitely got me interested, particularly with variations of add() & iterator.remove() methods. But is reimplementing and customizing a data structure something that is of more interest to the academics vs the real-world programmers? Has anyone reimplemented their own version of a data structure in a commercial application/program, and why did you pick that route over your particular language's implementation?

  • Getting input and output from a jar file run from java class?

    - by Jack L.
    Hi, I have a jar file that runs this code: public class InputOutput { /** * @param args * @throws IOException */ public static void main(String[] args) throws IOException { boolean cont = true; BufferedReader in = new BufferedReader(new InputStreamReader(System.in)); while (cont) { System.out.print("Input something: "); String temp = in.readLine(); if (temp.equals("end")) { cont = false; System.out.println("Terminated."); } else System.out.println(temp); } } } I want to program another java class that executes this jar file and can get the input and send output to it. Is it possible? The current code I have is this but it is not working: public class JarTest { /** * Test input and output of jar files * @author Jack */ public static void main(String[] args) { try { Process io = Runtime.getRuntime().exec("java -jar InputOutput.jar"); BufferedReader in = new BufferedReader(new InputStreamReader(io.getInputStream())); OutputStreamWriter out = new OutputStreamWriter(io.getOutputStream()); boolean cont = true; BufferedReader consolein = new BufferedReader(new InputStreamReader(System.in)); while (cont) { String temp = consolein.readLine(); out.write(temp); System.out.println(in.readLine()); } } catch (IOException e) { e.printStackTrace(); } } } Thanks for your help

  • How can you get a list or traversable tree of bookmarks from within a Firefox Extension?

    - by Nathan
    I am working on a simple Firefox Extension, and I need a list of the user's bookmarks. I have found the nsINavBookmarksService class which appears to be the recommended way of manipulating bookmarks since Firefox 3.0. Strangely I don't see a method that I could use to get a list of all the bookmarks in a folder. I need some way of creating a flat list of all the Bookmark URIs, but without any methods that return information about more than one bookmark I don't see a way to do it.

  • Determine if method is unsafe via reflection

    - by hmemcpy
    I'm looking for a way to filter out methods which have the unsafe modifier via reflection. It doesn't seem to be a method attribute. Is there a way? EDIT: it seems that this info is not in the metadata, at least I can't see it in the IL. However reflector shows the unsafe modifier in C# view. Any ideas on how it's done? Thanks!

    I have that code: ... request data = new request(); data.username = formNick; xml = data.Serialize(); ... [System.Serializable] public class request { public string username; public string password; static XmlSerializer serializer = new XmlSerializer(typeof(request)); public string Serialize() { StringBuilder builder = new StringBuilder(); XmlWriterSettings settings = new XmlWriterSettings(); settings.OmitXmlDeclaration = true; settings.Encoding = Encoding.UTF8; serializer.Serialize( System.Xml.XmlWriter.Create(builder, settings ), this); return builder.ToString(); } public static request Deserialize(string serializedData) { return serializer.Deserialize(new StringReader(serializedData)) as request; } } I want to add attributes to some nodes and create some sub-nodes. Also how to parse xml like that: <answer> <player id="2"> <coordinate axis="x"></coordinate> <coordinate axis="y"></coordinate> <coordinate axis="z"></coordinate> <action name="nothing"></action> </player> <player id="3"> <coordinate axis="x"></coordinate> <coordinate axis="y"></coordinate> <coordinate axis="z"></coordinate> <action name="boom"> <1>1</1> <2>2</2> </action> </player> </answer> p.s. it is not a xml file, it's answer from http server.

  • Ruby: How can I have a Hash take multiple keys?

    - by zxcvbnm
    I'm taking 5 strings (protocol, source IP and port, destination IP and port) and using them to store some values in a hash. The problem is that if the IPs or ports are switched between source and destination, the key is supposed to be the same. If I was doing this in C#/Java/whatever I'd have to create a new class and overwrite the hashcode()/equals() methods, but that seems error prone from the little I've read about it and I was wondering if there would be a better alternative here.

  • Swing verify code on event dispatch thread at runtime

    - by Jeff Storey
    Are there any libraries that instrument code to verify that methods called on swing components are called on the event dispatch thread? It probably wouldn't be too difficult to write some basic code for doing this, but I'm sure there are edge cases and whatnot that other people have handled. I'm looking for this at runtime though, not for unit tests. thanks, Jeff

  • Why Does This Maintainability Index Increase?

    - by Timothy
    I would be appreciative if someone could explain to me the difference between the following two pieces of code in terms of Visual Studio's Code Metrics rules. Why does the Maintainability Index increase slightly if I don't encapsulate everything within using ( )? Sample 1 (MI score of 71) public static String Sha1(String plainText) { using (SHA1Managed sha1 = new SHA1Managed()) { Byte[] text = Encoding.Unicode.GetBytes(plainText); Byte[] hashBytes = sha1.ComputeHash(text); return Convert.ToBase64String(hashBytes); } } Sample 2 (MI score of 73) public static String Sha1(String plainText) { Byte[] text, hashBytes; using (SHA1Managed sha1 = new SHA1Managed()) { text = Encoding.Unicode.GetBytes(plainText); hashBytes = sha1.ComputeHash(text); } return Convert.ToBase64String(hashBytes); } I understand metrics are meaningless outside of a broader context and understanding, and programmers should exercise discretion. While I could boost the score up to 76 with return Convert.ToBase64String(sha1.ComputeHash(Encoding.Unicode.GetBytes(plainText))), I shouldn't. I would clearly be just playing with numbers and it isn't truly any more readable or maintainable at that point. I am curious though as to what the logic might be behind the increase in this case. It's obviously not line-count.

  • Security of WCF endpoints

    - by Matt
    For the sake of argument, lets say that I've got a basicHttp WCF service. Besides implementing authentication (login/logout methods), what is stopping someone from just cracking open Visual Studio, adding a web reference to my website's service, and then playing playing around with my service? I'm not familiar with a method of stopping someone from doing this. The idea of someone downloading all of my Data/Operation contracts and then start playing around is keeping me up at night, and I like my sleep!

  • Problem when copying array of different types using Arrays.copyOf

    - by Shervin
    I am trying to create a method that pretty much takes anything as a parameter, and returns a concatenated string representation of the value with some delimiter. public static String getConcatenated(char delim, Object ...names) { String[] stringArray = Arrays.copyOf(names, names.length, String[].class); //Exception here return getConcatenated(delim, stringArray); } And the actual method public static String getConcatenated(char delim, String ... names) { if(names == null || names.length == 0) return ""; StringBuilder sb = new StringBuilder(); for(int i = 0; i < names.length; i++) { String n = names[i]; if(n != null) { sb.append(n.trim()); sb.append(delim); } } //Remove the last delim return sb.substring(0, sb.length()-1).toString(); } And I have the following JUnit test: final String two = RedpillLinproUtils.getConcatenated(' ', "Shervin", "Asgari"); Assert.assertEquals("Result", "Shervin Asgari", two); //OK final String three = RedpillLinproUtils.getConcatenated(';', "Shervin", "Asgari"); Assert.assertEquals("Result", "Shervin;Asgari", three); //OK final String four = RedpillLinproUtils.getConcatenated(';', "Shervin", null, "Asgari", null); Assert.assertEquals("Result", "Shervin;Asgari", four); //OK final String five = RedpillLinproUtils.getConcatenated('/', 1, 2, null, 3, 4); Assert.assertEquals("Result", "1/2/3/4", five); //FAIL However, the test fails on the last part with the exception: java.lang.ArrayStoreException at java.lang.System.arraycopy(Native Method) at java.util.Arrays.copyOf(Arrays.java:2763) Can someone spot the error?

  • How to know when my control changes size?

    - by Mason Wheeler
    I'm building a custom control, and I need it to be able to respond when it gets resized. I need the old dimensions and the new dimensions available in order to do some calculations. Unfortunately, the SetWidth and SetHeight methods are private to TControl, not protected, and so I can't override them. Is there any other way to know that my control's about to be resized, and to have the old size and the new size both available?

    I need to convert the below Sproc to a Linq query. At the very bottom is what I have so far. For reference the fields behind the "splat"(not my sproc) are ImmunizationID int, HAReviewID int, ImmunizationMaintID int, ImmunizationOther varchar(50), ImmunizationDate smalldatetime, ImmunizationReasonID int The first two are PK and FK, respectively.
