  • How do I work around the GCC "error: cast from ‘SourceLocation*’ to ‘int’ loses precision" error when compiling cmockery.c?

    - by Daryl Spitzer
    I need to add unit tests using Cmockery to an existing build environment that uses as hand-crafted Makefile. So I need to figure out how to build cmockery.c (without automake). When I run: g++ -DHAVE_CONFIG_H -DPIC -I ../cmockery-0.1.2 -I /usr/include/malloc -c ../cmockery-0.1.2/cmockery.c -o obj/cmockery.o I get a long list of errors like this: ../cmockery-0.1.2/cmockery.c: In function ‘void initialize_source_location(SourceLocation*)’: ../cmockery-0.1.2/cmockery.c:248: error: cast from ‘SourceLocation*’ to ‘int’ loses precision Here are lines 247:248 of cmockery.c: static void initialize_source_location(SourceLocation * const location) { assert_true(location); assert_true is defined on line 154 of cmockery.h: #define assert_true(c) _assert_true((int)(c), #c, __FILE__, __LINE__) So the problem (as the error states) is GCC doesn't like the cast from ‘SourceLocation*’ to ‘int’. I can build Cmockery using ./configure and make (on Linux, and on Mac OS X if I export CFLAGS=-I/usr/include/malloc first), without any errors. I've tried looking at the command-line that compiles cmockery.c when I run make (after ./configure): gcc -DHAVE_CONFIG_H -I. -I. -I./src -I./src -Isrc/google -I/usr/include/malloc -MT libcmockery_la-cmockery.lo -MD -MP -MF .deps/libcmockery_la-cmockery.Tpo -c src/cmockery.c -fno-common -DPIC -o .libs/libcmockery_la-cmockery.o ...but I don't see any options that might work around this error. In "error: cast from 'void*' to 'int' loses precision", I see I could change (int) in cmockery.h to (intptr_t). And I've confirmed that works. But since I can build Cmockery with ./configure and make, there must be a way to get it to build without modifying the source.

  • "Exception has been thrown by the target of an invocation" Running Tests - VS2008 SP1

    - by omatrot
    I'm using Visual Studio 2008 Team Suite and I'm unable to run tests and display the Test/Windows/Test Result Window. The result is a dialog box with the following content : "Exception has been thrown by the target of an invocation". Team Explorer has been installed after Visual Studio 2008 SP1. So I have re-apllied the service pack. Searching the web I found that this error is pretty common but unfortunately, the proposed solutions does not work for me. The problem was never analysed so I decided to give it a try : I reproduced the problem on a computer, attached the process with windbg and start with the basic investigations. Following are the first results : 0:000>!dumpstack OS Thread Id: 0xdb0 (0) Current frame: USER32!NtUserWaitMessage+0x15 ChildEBP RetAddr Caller,Callee 003fec94 75a32674 USER32!DialogBox2+0x222,

  • Problem with XElement and XslCompiledTransform

    - by Graham Clark
    I'm having some trouble using a combination of XElement and XslCompiledTransform. I've put the sample code I'm using below. If I get my input XML using the GetXmlDocumentXml() method, it works fine. If I use the GetXElementXml() method instead, I get an InvalidOperationException when calling the Transform method of XslComiledTransform: Token Text in state Start would result in an invalid XML document. Make sure that the ConformanceLevel setting is set to ConformanceLevel.Fragment or ConformanceLevel.Auto if you want to write an XML fragment. The CreateNavigator method on both XElement and XmlDocument returns an XPathNavigator. What extra stuff is XmlDocument doing so this all works, and how can I do the same with XElement? Am I just doing something insane? static void Main(string[] args) { XslCompiledTransform stylesheet = GetStylesheet(); // not shown for brevity IXPathNavigable input = this.GetXElementXml(); using (MemoryStream ms = this.TransformXml(input, stylesheet)) { XmlReader xr = XmlReader.Create(ms); xr.MoveToContent(); } } private MemoryStream TransformXml( IXPathNavigable xml, XslCompiledTransform stylesheet) { MemoryStream transformed = new MemoryStream(); XmlWriter writer = XmlWriter.Create(transformed); stylesheet.Transform(xml, null, writer); transformed.Position = 0; return transformed; } private IXPathNavigable GetXElementXml() { var xml = new XElement("x", new XElement("y", "sds")); return xml.CreateNavigator(); } private IXPathNavigable GetXmlDocumentXml() { var xml = new XmlDocument(); xml.LoadXml("<x><y>sds</y></x>"); return xml.CreateNavigator(); }

  • Zend Framework subdomain+subfolder router rewrite problem

    - by zf_novice
    I'm new to Zend Framwork and this is an issue I've been struggling for several hours already... I'm trying to chain Hostname and standard Route in order to get url with subdomain+subfolders ie.: http:// lang.mydomain.com/myapplication/public/controller http:// lang.mydomain.com/myapplication/public/controller/action (sorry for the empty space in the address, this site won't allow links) Basically what I have done in Bootstrap is: // add language to default route $routePath = new Zend_Controller_Router_Route( ':controller/:action/*', array('controller'=>'index','action' => 'index','module'=>'default') ); $routeHostname = new Zend_Controller_Router_Route_Hostname( ':lang.mydomain.com', array('lang'=>$lang) ); $frontController = $this->getResource('FrontController'); $router = $frontController->getRouter(); $router->addRoute('default', $routeHostname->chain($routePath)) $frontController->setRouter($router); it finds the route ok, but every time I generate url in view or layout by $this-url() <?php echo $this->url( array( 'controller'=> 'guestbook', 'action' => 'sign', 'lang' => Zend_Registry::get('lang'), ), 'default', true) ?>"> I get http:// lang.mydomain.com/controller instead of http:// lang.mydomain.com/myapplication/public/controller I've been trying to set baseUrl on front controller but no luck... Also I've tried the static route with myapplication/public or following standard route: 'myapplication/public/:controller/:action/*' - it result with "An error occurred Page not found Exception information: Message: No route matched the request" and empty request Is there any way to assembly subdomain with subfolder in Zend Framwork?? EDIT: I changed above to: $frontController->setBaseUrl('.'); // add language to default route $routePath = new Zend_Controller_Router_Route( 'quickstart/public/:controller/:action/*', array( 'controller'=>'index', 'action' => 'index', 'module'=>'default', ) ); and it works form me, although I'm not sure whether it's been correct approach...

  • Xcode Link Frameworks "Relative to Current SDK" Doesn't Work When Mixing Mac Framework and iPhone St

    - by bl4th3rsk1t3
    I have a framework of code I maintain. It's got mac and iphone objective-c code. And some of it is shared. I'm not having any problems with code. It's a problem with Xcode. Let's just call my framework "AwesomeKit" for this problem. The first thing I did was create an xcode Framework project called "AwesomeKit". Add source files to it, link against the common mac frameworks: foundation, cocoa, carbon, etc. It compiles fine. Then, add a new "static library" target, let's call it "AwesomeKit-iPhone" and set the base SDK in the build settings to iphone device 3.1.3. The problem comes when I try to add "Existing Frameworks" to the AweseomKit-iPhone target. -First change the current build target to AwesomeKit-iPhone. -Right click on any group and select "Add Existing Frameworks..." -Choose UIKit.framework UIKit will immediately be highlighted red, as if it's missing. It is indeed missing because Xcode uses the "Relative SDK" setting from the "Mac OS 10.6" SDK. When it should be using it relative to the current target's base sdk iphone device 3.1.3. What the heck? Has anyone experienced this? This is really annoying.

  • Parallel port with C#

    - by Michael S.
    Hello, I am trying to send data to LPT1 port with a C# program, unfortunately with no success.. I am using windows 7 x64. I tried both x86 and x64 (inpoutx64.dll) dll's.. With the x64 dll when I send: Output(888, 255); It just continues the program as everything went ok, but i can't see anything on my multimeter (only the static 0.02V).. I also tried the following with C++: int main () { int val = 0; printf("Enter a value\n"); scanf("%d", &val); _outp(0x378, val); getchar(); _outp(0x378, 0); return 0; } But it throws an exception: Unhandled exception at 0x01281428 in ppac.exe: 0xC0000096: Privileged instruction. I remember once I made something like this work on xp, I hope it's possible on win7 too.. Please help me with this. Thanks.

Any help would rock.

  • How Can i reload data in tableview in view controller in iphone

    - by Pugal Devan
    Hi, I am new to iphone development. I have created 5 buttons in the view. On clicking the buttons it navigates to the corresponding views. On clicking the "News" button it navigates and displayed the parsing details in the table view.(This table view, I have created View controller and added table view using Interface Builder and i have set all the properties.) and i go to another button and comes back to the "News" button, every time parsing will happened.How to avoid the multiple parsing when i come back to the button. i have tried this one and my code is, - (void)viewDidAppear:(BOOL)animated { [super viewDidAppear:animated]; static int i; if(i == 0) { NSString * path = @"http://www.AAAAAAAAAAAAAAAA.com"; [self parseXMLFileAtURL:path]; i++; } [self.newsTable reloadData]; } } Now the parsing is happened only time but the datas are doesnt displayed. My problem is the tableview doesnot reload. newsTable is the instance of the Tableview. How can i achieve this. Please help me out. Thanks.

  • user input question

    - by jdbeverly87
    My program checks to test if a word or phrase is a palindrome (reads the same both backward and forward, ex "racecar"). The issue I'm having is after someone enters in "racecar" getting it to actually test. In the below code, I marked where if I type in "racecar" and run, Java returns the correct answer so I know I'm right there. But what am I missing as far as entering it into the console. I think my code is ok, but maybe I have something missing or in the wrong spot? Not really looking for a new answer unless I'm missing something, but if possible perhaps a pro at this moving my code to the correct area bc I'm stuck! `import java.util.*; public class Palindrome { public static void main(String[] args) { String myInput; Scanner in = new Scanner(System.in); System.out.println("Enter a word or phrase: "); **//this asks user for input but doesn't check for whether or not it is a palindrome** myInput = in.nextLine(); in.close(); System.out.println("You entered: " + myInput); } { String s="racecar"; **//I can type a word here and it works but I need** int i; **//I need it to work where I ask for the input** int n=s.length(); String str=""; for(i=n-1;i>=0;i--) str=str+s.charAt(i); if(str.equals(s)) System.out.println(s+ " is a palindrome"); else System.out.println(s+ " is not a palindrome"); } }` I'm new at programming so I'm hoping what I got is ok. I know the palindrome test works I'm just needing helping having it test thru where I'm entering it into the console. Thanks

    I have a WCF service running, I added a reference to the service by using Add Service Reference in the solution explorer, and I checked the box for create asynchronous operations.

  • LINQ(2 SQL) Insert Multiple Tables Question

    - by Refracted Paladin
    I have 3 tables. A primary EmploymentPlan table with PK GUID EmploymentPlanID and 2 FK's GUID PrevocServicesID & GUID JobDevelopmentServicesID. There are of course other fields, almost exclusively varchar(). Then the 2 secondary tables with the corresponding PK to the primary's FK's. I am trying to write the LINQ INSERT Method and am struggling with the creation of the keys. Say I have a method like below. Is that correct? Will that even work? Should I have seperate methods for each? Also, when INSERTING I didn't think I needed to provide the PK for a table. It is auto-generated, no? Thanks, public static void InsertEmploymentPlan(int planID, Guid employmentQuestionnaireID, string user, bool communityJob, bool jobDevelopmentServices, bool prevocServices, bool transitionedPrevocIntegrated, bool empServiceMatchPref) { using (var context = MatrixDataContext.Create()) { var empPrevocID = Guid.NewGuid(); var prevocPlan = new tblEmploymentPrevocService { EmploymentPrevocID = empPrevocID }; context.tblEmploymentPrevocServices.InsertOnSubmit(prevocPlan); var empJobDevID = Guid.NewGuid(); var jobDevPlan = new tblEmploymentJobDevelopmetService() { JobDevelopmentServicesID = empJobDevID }; context.tblEmploymentJobDevelopmetServices.InsertOnSubmit(jobDevPlan); var empPlan = new tblEmploymentQuestionnaire { CommunityJob = communityJob, EmploymentQuestionnaireID = Guid.NewGuid(), InsertDate = DateTime.Now, InsertUser = user, JobDevelopmentServices = jobDevelopmentServices, JobDevelopmentServicesID =empJobDevID, PrevocServices = prevocServices, PrevocServicesID =empPrevocID, TransitionedPrevocToIntegrated =transitionedPrevocIntegrated, EmploymentServiceMatchPref = empServiceMatchPref }; context.tblEmploymentQuestionnaires.InsertOnSubmit(empPlan); context.SubmitChanges(); } } I understand I can use more then 1 InsertOnSubmit, See SO ? HERE, I just don't understand how that would apply to my situation and the PK/FK creation.

  • Extend hasMap to add putChildren method

    - by denny
    Hi all, i have question, i want to develop a programme about extend the hashmap to add putchildren method.. I wrote main class, but now i wanna write putChildrenValue method.. My question is : i need to implement a putChildrenValue method with 3 parameters, String key, String key, ObjectValue. It will store the system as described above accordingly. When i finished this method When you finish the method data Key1 = "RUBY" value=HashMap which has -> "key2" = 5248 && "VALUE" = German Key1 = "PHYTON" value=HashMap which has -> "key2" = 1234 && -> "VALUE" = German My main class is : public static void main(String [] args) { ExtendedHashMap extendedMap = new ExtendedHashMap(); extendedMap.put (“Row1”, “Column1”, “German”); extendedMap.put (“Row1”, “Column2”, “English”); extendedMap.put (“Row1”, “Column3”, “Spanish”); extendedMap.put (“Row2”, “Column1”, “Ruby”); extendedMap.put (“Row2”, “Column2”, “Phyton”); extendedMap.put (“Row3”, “Column3”, “Java”); } Can anyone help me?

  • Performance penalty of typecasting and boxing/unboxing types in C# when storing generic values

    - by kitsune
    I have a set-up similar to WPF's DependencyProperty and DependencyObject system. My properties however are generic. A BucketProperty has a static GlobalIndex (defined in BucketPropertyBase) which tracks all BucketProperties. A Bucket can have many BucketProperties of any type. A Bucket saves and gets the actual values of these BucketProperties... now my question is, how to deal with the storage of these values, and what is the penalty of using a typecasting when retrieving them? I currently use an array of BucketEntries that save the property values as simple objects. Is there any better way of saving and returning these values? Beneath is a simpliefied version: public class BucketProperty<T> : BucketPropertyBase { } public class Bucket { private BucketEntry[] _bucketEntries; public void SaveValue<T>(BucketProperty<T> property, T value) { SaveBucketEntry(property.GlobalIndex, value) } public T GetValue<T>(BucketProperty<T> property) { return (T)FindBucketEntry(property.GlobalIndex).Value; } } public class BucketEntry { private object _value; private uint _index; public BucketEntry(uint globalIndex, object value) { ... } }

  • WPF Exposing a calculated property for binding (as DependencyProperty)

    - by kubal5003
    Hello, I have a complex WPF control that for some reasons (ie. performance) is not using dependency properties but simple C# properties (at least at the top level these are exposed as properties). The goal is to make it possible to bind to some of those top level properties - I guess I should declare them as DPs.(right? or is there some other way to achieve this? ) I started reading on MSDN about DependencyProperties and DependencyObjects and found an example: public class MyStateControl : ButtonBase { public MyStateControl() : base() { } public Boolean State { get { return (Boolean)this.GetValue(StateProperty); } set { this.SetValue(StateProperty, value); } } public static readonly DependencyProperty StateProperty = DependencyProperty.Register( "State", typeof(Boolean), typeof(MyStateControl),new PropertyMetadata(false)); } If I'm right - this code enforces the property to be backed up by DependencyProperty which restricts it to be a simple property with a store(from functional point of view, not technically) instead of being able to calculate the property value each time getter is called and setting other properties/fields each time setter is called. What can I do about that? Is there any way I could make those two worlds meet at some point?

  • Enum "does not have a no-arg default constructor" with Jaxb and cxf

    - by Dave
    A client is having an issue running java2ws on some of their code, which uses & extends classes that are consumed from my SOAP web services. Confused yet? :) I'm exposing a SOAP web service (JBoss5, Java 6). Someone is consuming that web service with Axis1 and creating a jar out of it with the data types and client stubs. They are then defining their own type, which extends one of my types. My type contains an enumeration. class MyParent { private MyEnumType myEnum; // getters, settters for myEnum; } class TheirChild extends MyParent { ... } When they are running java2ws on their code (which extends my class), they get Caused by: com.sun.xml.bind.v2.runtime.IllegalAnnotationsException: 2 counts of IllegalAnnotationExceptions net.foo.bar.MyEnuMType does not have a no-arg default constructor. this problem is related to the following location: at net.foo.bar.MyEnumType at public net.foo.bar.MyEnumType net.foo.bar.MyParent.getMyEnum() The enum I've defined is below. This is now how it comes out after being consumed, but it's how I have it defined on the app server: @XmlType(name = "MyEnumType") @XmlEnum public enum MyEnumType { Val1("Val1"), Val2("Val2") private final String value; MyEnumType(String v) { value = v; } public String value() { return value; } public static MyEnumType fromValue(String v) { if (v == null || v.length() == 0) { return null; } if (v.equals("Val1")) { return MyEnumType.Val1; } if (v.equals("Val2")) { return MyEnumType.Val2; } return null; } } I've seen things online and other posts, like (this one) regarding Jaxb's inability to handle Lists or things like that, but I'm baffled about my enum. I'm pretty sure you can't have a default constructor for an enum (well, at least a public no-arg constructor, Java yells at me when I try), so I'm not sure what makes this error possible. Any ideas? Also, the "2 counts of IllegalAnnotationsExceptions" may be because my code actually has two enums that are written similarly, but I left them out of this example for brevity.

  • Issues with cross-domain uploading

    - by meder
    I'm using a django plugin called django-filebrowser which utilizes uploadify. The issue I'm having is that I'm hosting uploadify.swf on a remote static media server, whereas my admin area is on my django server. At first, the browse button wouldn't invoke my browser's upload. I fixed this by modifying the sameScriptAccess to always instead of sameDomain. Now the progress bar doesn't move at all, I probably have to enable some server setting for cross domain file uploading, or most likely actually host a separate upload script on my media server. I thought I could solve this by adding a crossdomain.xml to enable any site at the root of both servers, but that doesn't seem to solve it. $(document).ready(function() { $('#id_file').uploadify({ 'uploader' : 'http://media.site.com:8080/admin/filebrowser/uploadify/uploadify.swf', 'script' : '/admin/filebrowser/upload_file/', 'scriptData' : {'session_key': '...'}, 'checkScript' : '/admin/filebrowser/check_file/', 'cancelImg' : 'http://media.site.com:8080/admin/filebrowser/uploadify/cancel.png', 'auto' : false, 'folder' : '', 'multi' : true, 'fileDesc' : '*.html;*.py;*.js;*.css;*.jpg;*.jpeg;*.gif;*.png;*.tif;*.tiff;*.mp3;*.mp4;*.wav;*.aiff;*.midi;*.m4p;*.mov;*.wmv;*.mpeg;*.mpg;*.avi;*.rm;*.pdf;*.doc;*.rtf;*.txt;*.xls;*.csv;', 'fileExt' : '*.html;*.py;*.js;*.css;*.jpg;*.jpeg;*.gif;*.png;*.tif;*.tiff;*.mp3;*.mp4;*.wav;*.aiff;*.midi;*.m4p;*.mov;*.wmv;*.mpeg;*.mpg;*.avi;*.rm;*.pdf;*.doc;*.rtf;*.txt;*.xls;*.csv;', 'sizeLimit' : 10485760, 'scriptAccess' : 'always', //'scriptAccess' : 'sameDomain', 'queueSizeLimit' : 50, 'simUploadLimit' : 1, 'width' : 300, 'height' : 30, 'hideButton' : false, 'wmode' : 'transparent', translations : { browseButton: 'BROWSE', error: 'An Error occured', completed: 'Completed', replaceFile: 'Do you want to replace the file', unitKb: 'KB', unitMb: 'MB' } }); $('input:submit').click(function(){ $('#id_file').uploadifyUpload(); return false; }); }); The page I'm viewing this on is http://site.com/admin/filebrowser/browse on port 80.

  • Creating generic list of instances of a class.

    - by Jim Branson
    I have several projects where I build a dictionary from a small class. I'm using C# 2008, Visual studio 2008 and .net 3.5 This is the code: namespace ReportsTest { class Junk { public static Dictionary<string, string> getPlatKeys() { Dictionary<string, string> retPlatKeys = new Dictionary<string, string>(); SqlConnection conn = new SqlConnection("Data Source=JB55LTARL;Initial Catalog=HldiReports;Integrated Security=True"); SqlDataReader Dr = null; conn.Open(); SqlCommand cmnd = new SqlCommand("SELECT Make, Series, RedesignYear, SeriesName FROM CompPlatformKeys", conn); Dr = cmnd.ExecuteReader(); while (Dr.Read()) { utypPlatKeys rec = new utypPlatKeys(Dr); retPlatKeys.Add(rec.Make + rec.Series + rec.RedesignYear, rec.SeriesName); } conn = null; Dr = null; return retPlatKeys; } } public class utypPlatKeys { public string Make { get; set; } public string Series { get; set; } public string RedesignYear { get; set; } public string SeriesName { get; set; } public utypPlatKeys(SqlDataReader dr) { this.Make = dr.GetInt16(dr.GetOrdinal("Make")).ToString("D3"); this.Series = dr.GetInt16(dr.GetOrdinal("Series")).ToString("D3"); this.RedesignYear = dr.GetInt16(dr.GetOrdinal("RedesignYear")).ToString(); this.SeriesName = dr["SeriesName"].ToString(); } } } The immediate window shows all of the entries in retPlatKeys and if you hover over retPlatKeys after loading it indicates the number of elements like this: "retPlatKeys| Count = 923 which is correct. I went to create a new project using this pattern only now the immediate window says retPlatKeys is out of scope and hovering over retPlatKeys after loading I get something like retPlatKeys|0x0000000002578900. Any help is greatly appreciated.

  • Site Security/Access management for asp.net mvc application

    - by minal
    I am trying to find a good pattern to use for user access validation. Basically on a webforms application I had a framework which used user roles to define access, ie, users were assigned into roles, and "pages" were granted access to a page. I had a table in the database with all the pages listed in it. Pages could have child pages that got their access inherited from the parent. When defining access, I assigned the roles access to the pages. Users in the role then had access to the pages. It is fairly simple to manage as well. The way I implemented this was on a base class that every page inherited. On pageload/init I would check the page url and validate access and act appropriately. However I am now working on a MVC application and need to implement something similar, however I can't find a good way to make my previous solution work. Purely because I don't have static pages as url paths. Also I am not sure how best to approach this as I now have controllers rather then aspx pages. I have looked at the MVCSitemapprovider, but that does not work off a database, it needs a sitemap file. I need control of changing user persmissions on the fly. Any thoughts/suggestions/pointers would be greatly appreciated.

  • Rewriting URL's in codeigniter with url_title()?

    - by Craig Ward
    I am rewriting my website with codeigniter and have something I want to do but not sure it is possible. I have a gallery on my site powered by the Flickr API. Here is an example of the code I use to display the Landscape pictures: <?php foreach ($landscapes->photoset->photo as $l->photoset->photo) : ?> <a >photoset->photo->farm ?>/<?php echo $l->photoset->photo->server ?>/<?php echo $l->photoset->photo->id ?>/<?php echo $l->photoset->photo->secret ?>/<?php echo $l->photoset->photo->title ?>'> <img class='f_thumb'>photoset->photo->farm ?>.static.flickr.com/<?php echo $l->photoset->photo->server ?>/<?php echo $l->photoset->photo->id ?>_<?php echo $l->photoset->photo->secret ?>_s.jpg' title='<?php echo $l->photoset->photo->title ?>' alt='<?php echo $l->photoset->photo->title ?>' /></a> <?php endforeach; ?> As you can see when a user clicks on a picture I pass over the Farm, Server, ID, Secret and Title elements using URI segments and build the page in the controller using $data['farm'] = $this->uri->segment(3); $data['server'] = $this->uri->segment(4); $data['id'] = $this->uri->segment(5); $data['secret'] = $this->uri->segment(6); $data['title'] = $this->uri->segment(7); Everything works and is fine but the URL’s are a tad long, example “http://localhost:8888/wip/index.php/gallery/focus/3/2682/4368875046/e8f97f61d9/Old Mill House in Donegal” Is there a way to rewrite the URL so its more like “http://localhost:8888/wip/index.php/gallery/focus/Old_Mill_House_in_Donegal” I was looking at using: $url_title = $this->uri->segment(7); $url_title = url_title($url_title, 'underscore', TRUE); But I don’t seem to be able to get it to work. Any ideas?

  • Checking if a RoutedEvent has any handlers

    - by AK
    I've got a custom Button class, that always performs the same action when it gets clicked (opening a specific window). I'm adding a Click event that can be assigned in the button's XAML, like a regular button. When it gets clicked, I want to execute the Click event handler if one has been assigned, otherwise I want to execute the default action. The problem is that there's apparently no way to check if any handlers have been added to an event. I thought a null check on the event would do it: if (Click == null) { DefaultClickAction(); } else { RaiseEvent(new RoutedEventArgs(ClickEvent, this));; } ...but that doesn't compile. The compiler tells me that I can't do anything other than += or -= to an event outside of the defining class, event though I'm trying to do this check INSIDE the defining class. I've implemented the correct behavior myself, but it's ugly and verbose and I can't believe there isn't a built-in way to do this. I must be missing something. Here's the relevant code: public class MyButtonClass : Control { //... public static readonly RoutedEvent ClickEvent = EventManager.RegisterRoutedEvent("Click", RoutingStrategy.Bubble, typeof(RoutedEventHandler), typeof(MyButtonClass)); public event RoutedEventHandler Click { add { ClickHandlerCount++; AddHandler(ClickEvent, value); } remove { ClickHandlerCount--; RemoveHandler(ClickEvent, value); } } private int ClickHandlerCount = 0; private Boolean ClickHandlerExists { get { return ClickHandlerCount > 0; } } //... }

  • Using ASP .NET Membership and Profile with MVC, how can I create a user and set it to HttpContext.Cu

    - by Jeremy Gruenwald
    I've read the other questions on the topic of MVC membership and profiles, but I'm missing something. I implemented a custom Profile object in code as described by Joel here: http://stackoverflow.com/questions/426609/asp-net-membership-how-to-assign-profile-values I can't get it to work when I'm creating a new user, however. When I do this: Membership.CreateUser(userName, password); Roles.AddUserToRole(userName, "MyRole"); the user is created and added to a role in the database, but HttpContext.Current.User is still empty, and Membership.GetUser() returns null, so this (from Joel's code) doesn't work: static public AccountProfile CurrentUser { get { return (AccountProfile) (ProfileBase.Create(Membership.GetUser().UserName)); } } AccountProfile.CurrentUser.FullName = "Snoopy"; I've tried calling Membership.GetUser(userName) and setting Profile properties that way, but the set properties remain empty, and calling AccountProfile.CurrentUser(userName).Save() doesn't put anything in the database. I've also tried indicating that the user is valid & logged in, by calling Membership.ValidateUser, FormsAuthentication.SetAuthCookie, etc., but the current user is still null or anonymous (depending on the state of my browser cookies). I have the feeling I'm missing some essential piece of understanding about how Membership, Authentication, and Profiles fit together. Do I have to do a round trip before the current User will be populated? Any advice would be much appreciated.

  • Right way to dispose Image/Bitmap and PictureBox

    - by kornelijepetak
    I am trying to develop a Windows Mobile 6 (in WF/C#) application. There is only one form and on the form there is only a PictureBox object. On it I draw all desired controls or whatever I want. There are two things I am doing. Drawing custom shapes and loading bitmaps from .png files. The next line locks the file when loading (which is an undesired scenario): Bitmap bmp = new Bitmap("file.png"); So I am using another way to load bitmap. public static Bitmap LoadBitmap(string path) { using (Bitmap original = new Bitmap(path)) { return new Bitmap(original); } } This is I guess much slower, but I don't know any better way to load an image, while quickly releasing the file lock. Now, when drawing an image there is method that I use: public void Draw() { Bitmap bmp = new Bitmap(240,320); Graphics g = Graphics.FromImage(bmp); // draw something with Graphics here. g.Clear(Color.Black); g.DrawImage(Images.CloseIcon, 16, 48); g.DrawImage(Images.RefreshIcon, 46, 48); g.FillRectangle(new SolidBrush(Color.Black), 0, 100, 240, 103); pictureBox.Image = bmp; } This however seems to be some kind of a memory leak. And if I keep doing it for too long, the application eventually crashes. Therefor, I have X questions: 1.) What is the better way for loading bitmaps from files without locking the file? 2.) What objects needs to be manually disposed in the Draw() function (and in which order) so there's no memory leak and no ObjectDisposedException throwing? 3.) If pictureBox.Image is set to bmp, like in the last line of the code, would pictureBox.Image.Dispose() dispose only resources related to maintaining the pictureBox.Image or the underlying Bitmap set to it?

  • Calling a method with an arg of Class<T> where T is a parameterized type

    - by Brian Ferris
    I'm attempting to call a constructor method that looks like: public static SomeWrapper<T> method(Class<T> arg); When T is an unparameterized type like String or Integer, calling is straightforward: SomeWrapper<String> wrapper = method(String.class); Things get tricky when T is a parameterized type like List<String>. The following is not valid: SomeWrapper<List<String>> wrapper = method(List<String>.class); About the only thing I could come up with is: List<String> o = new ArrayList<String>(); Class<List<String>> c = (Class<List<String>>) o.getClass(); SomeWrapper<List<String>> wrapper = method(c); Surely there is an easier way that doesn't require the construction of an additional object?
