  • How can I determine whether or not to add project items using IWizard?

    - by taarskog
    Hi, I am generating entity wrappers in VS2010 based on dynamic objects in a CRM system. In addition to the entity code, I want to add an EntityBase of which all entities inherit from. If the file exists in the project from before, it should not be added. I am using an IWizard implementation to give the generator the object names etc. Is it possible in the IWizard implementation to determine whether or not to add an item if it exists in the project from before? How do I get a hold of the project handle and its items in or before the ShouldAddProjectItem method? My code so far (not completed): public class EntityWizardImplementation : IWizard { public void BeforeOpeningFile(ProjectItem projectItem) { //Note: Nothing here. } public void ProjectFinishedGenerating(Project project) { //Note: Nothing here. } public void ProjectItemFinishedGenerating(ProjectItem projectItem) { //Note: Nothing here. } public void RunFinished() { //Note: Nothing here. } public void RunStarted(object automationObject, Dictionary<string, string> replacementsDictionary, WizardRunKind runKind, object[] customParams) { try { var window = new WizardWindow(); // Replace parameters gathered from the wizard replacementsDictionary.Add("$crmEntity$", window.CrmEntity); replacementsDictionary.Add("$crmOrganization$", window.CrmOrganization); replacementsDictionary.Add("$crmMetadataServiceUrl$", window.CrmMetadataUrl); window.Close(); } catch (SoapException se) { MessageBox.Show(se.ToString()); } catch (Exception e) { MessageBox.Show(e.ToString()); } } public bool ShouldAddProjectItem(string filePath) { // This is where I assume it is correct to handle the preexisting file. return true; } }

  • How to handle ctrl+arrow in Javascript?

    - by MartyIX
    I've noticed an problem when trying to catch keyboard shortcut: CTRL+an arrow. I've handled keydown event. Now when I hold CTRL key then keydown event is fired once. If I hold an arrow (so that now I'm holding CTRL+an arrow) it doesn't fire another event. Is it forbidden from any reason? I guess I've already encountered this problem in Opera a few years ago and there was an option for it in browser. My results: holding CTRL, press an arrow -- fires event for CTRL and doesn't fire an event for an arrow press CTRL + an arrow at once -- fires one event but only with keycode of CTRL. holding CTRL, press a letter (eg. S) -- works as expected press CTRL + letter (eg. S) -- works as expected (Results are identical in Chrome and Firefox. Is the behaviour described above a standard?) I'm using: function OnKeyDown(e) { } e.ctrlKey, e.which properties of event The question is: what might be the problem?

  • Rails 3: Link_to :remote => true with JQuery?

    - by Derek
    Question update: I have figured out that importing JQuery (even without using it at all) is causing :remote => true to not work properly. I get the following error in the Chrome console: Uncaught TypeError: Object [object Object] has no method 'dispatchEvent' (prototype.js:5653) And when the link is clicked, it throws the same error again before redirecting. Responder.erb.html <ul> <% @choices.each_with_index do |choice, index| %> <li><%= link_to choice, { :action => "submit_response", :id => @id, :response => index }, :remote => true %></li> <% end %> </ul> Example generated HTML: <ul> <li><a href="/poller/submit_response/yni?response=0" data-remote="true">True</a></li> <li><a href="/poller/submit_response/yni?response=1" data-remote="true">False</a></li> </ul>

  • How to split this string and identify first sentence after last '*'?

    - by DaveDev
    I have to get a quick demo for a client, so this is a bit hacky. Please don't flame me too much! :-) I'm getting a string similar to the following back from the database: The object of the following is to do: * blah 1 * blah 2 * blah 3 * blah 4. Some more extremely uninteresting text. Followed by yet another sentence full of extrememly uninteresting text. Thankfully this is the last sentence. I need to format this so that each * represents a bullet point, and the sentence after the last * goes onto a new line, ideally as follows: The object of the following is to do: blah 1 (StackOverflow wants to add bullet points here, but I just need '*') blah 2 blah 3 blah 4. Some more extremely uninteresting text. Followed by yet another sentence full of extrememly uninteresting text. Thankfully this is the last sentence. It's easy enough to split the string by the * character and replace that with <br /> *. I'm using the following for that: string description = GetDescription(); description = description.Replace("*", "<br />*"); // it's going onto a web page. but the result this gives me is: The object of the following is to do: blah 1 blah 2 blah 3 blah 4. Some more extremely uninteresting text. Followed by yet another sentence full of extrememly uninteresting text. Thankfully this is the last sentence. I'm having a bit of difficulty identifying the fist sentence after the last '*' so I can put a break there too. Can somebody show me how to do this?

  • ref and out parameters in C# and cannot be marked as variant.

    - by Water Cooler v2
    What does the statement mean? From here ref and out parameters in C# and cannot be marked as variant. 1) Does it mean that the following can not be done. public class SomeClass<R, A>: IVariant<R, A> { public virtual R DoSomething( ref A args ) { return null; } } 2) Or does it mean I cannot have the following. public delegate R Reader<out R, in A>(A arg, string s); public static void AssignReadFromPeonMethodToDelegate(ref Reader<object, Peon> pReader) { pReader = ReadFromPeon; } static object ReadFromPeon(Peon p, string propertyName) { return p.GetType().GetField(propertyName).GetValue(p); } static Reader<object, Peon> pReader; static void Main(string[] args) { AssignReadFromPeonMethodToDelegate(ref pReader); bCanReadWrite = (bool)pReader(peon, "CanReadWrite"); Console.WriteLine("Press any key to quit..."); Console.ReadKey(); } I tried (2) and it worked.

  • jquery displaying table rows dynamically in dom belonging to one/more particular class

    - by whatf
    I have the basic html structure: <table> <tbody> <tr class="1"> <td> <p style="font-size:large"> <span class="muted"> This is the first object </span> </p> </td> </tr> <tr class="2"> <td> <p style="font-size:large"> <span class="muted"> This is second object </span> </p> </td> </tr> <tr class="3"> <p style="font-size:large"> <span class="muted"> this is the third object </span> </p> </td> </tr> </tbody> </table> and then I have check boxes, the functionality i want is, if checkbox 1 is checked, only the tr with class 1 be displayed. if checkbox 2 and 3 are clicked, the tr with class 1 gets hidden and 2, 3 show in the dom. again if checkbox 2,*3* are unchecked and 1 is checked tr with class 2, 3 do not show and 1 is showed. How can this be done in jQuery?

  • Another php array looping question

    - by Dan
    Been battling with this one for what seems, like forever. I have an array: $url_array It contains this info: Array ( [ppp] => Array ( [0] => stdClass Object ( [id] => 46660 [entity_id] => 0 [redirect_url] => http://www.google.com [type] => Image ) [1] => stdClass Object ( [id] => 52662 [entity_id] => 0 [pixel_redirect_url] => http://www.yahoo.com [type] => Image ) [2] => stdClass Object ( [id] => 53877 [entity_id] => 0 [redirect_url] => http://www.msn.com [pixel_type] => Image ) ) [total_count] => 3 ) I need to loop through it, and do things to each variable. I can get this to work: foreach ($piggies_array as $key => $value) { $id = $value[0]->id; $redirect_url = $value[0]->redirect_url; } Not unsurprisingly, it's only echoing the first value of those variables, but no matter what I try I cannot get it to loop through: $value->redirect_url; $value=>redirect_url; I would appreciate any help.

  • Java JCheckBox ArrayList help needed

    - by user2929626
    I'm new to Java and struggling with something which I'm sure must have a simple answer but I can't seem to find it. I have an array of checkbox objects defined as: ArrayList<JCheckBox> checkBoxList A JPanel is created with a grid layout and the checkboxes are added to the JPanel and the ArrayList: for (int i = 0; i < 256; i++) { JCheckBox c = new JCheckBox(); c.setSelected(false); checkBoxList.add(c); mainPanel.add(c); } Yes, there are 256 checkboxes! The panel is added to a JFrame and eventually the GUI is displayed. The user can select any combination of the 256 checkboxes. My class implements Serializable and this ArrayList of checkboxes can be saved and restored using 'Save' and 'Load' GUI buttons. My code to load the saved object is as below: public class LoadListener implements ActionListener { public void actionPerformed(ActionEvent a) { try { // Prompt the user for a load file JFileChooser fileLoad = new JFileChooser(); fileLoad.showOpenDialog(mainFrame); // Create a object/file input stream linking to the selected file ObjectInputStream is = new ObjectInputStream(new FileInputStream(fileLoad.getSelectedFile())); // Read the checkBox array list checkBoxList = (ArrayList<JCheckBox>) is.readObject(); is.close(); } catch (Exception ex) { ex.printStackTrace(); } } On loading the ArrayList object, the values of the checkboxes are correctly populated, however I want to update the checkboxes on the GUI to reflect this. Is there an easy way to do this? I assumed as the array of checkboxes had the correct values that I could just repaint the panel / frame but this doesn't work. I'd like to understand why - does my loaded array of checkbox objects no longer reflect the checkbox objects on the GUI? Any help would be much appreciated. Thanks!

  • ARC and __unsafe_unretained

    - by J Shapiro
    I think I have a pretty good understanding of ARC and the proper use cases for selecting an appropriate lifetime qualifiers (__strong, __weak, __unsafe_unretained, and __autoreleasing). However, in my testing, I've found one example that doesn't make sense to me. As I understand it, both __weak and __unsafe_unretained do not add a retain count. Therefore, if there are no other __strong pointers to the object, it is instantly deallocated. The only difference in this process is that __weak pointers are set to nil, and __unsafe_unretained pointers are left alone. If I create a __weak pointer to a simple, custom object (composed of one NSString property), I see the expected (null) value when trying to access a property: Test * __weak myTest = [[Test alloc] init]; myTest.myVal = @"Hi!"; NSLog(@"Value: %@", myTest.myVal); // Prints Value: (null) Similarly, I would expect the __unsafe_unretained lifetime qualifier to cause a crash, due to the resulting dangling pointer. However, it doesn't. In this next test, I see the actual value: Test * __unsafe_unretained myTest = [[Test alloc] init]; myTest.myVal = @"Hi!"; NSLog(@"Value: %@", myTest.myVal); // Prints Value: Hi! Why doesn't the __unsafe_unretained object become deallocated?

  • Python "callable" attribute (pseudo-property)

    - by mgilson
    In python, I can alter the state of an instance by directly assigning to attributes, or by making method calls which alter the state of the attributes: foo.thing = 'baz' or: foo.thing('baz') Is there a nice way to create a class which would accept both of the above forms which scales to large numbers of attributes that behave this way? (Shortly, I'll show an example of an implementation that I don't particularly like.) If you're thinking that this is a stupid API, let me know, but perhaps a more concrete example is in order. Say I have a Document class. Document could have an attribute title. However, title may want to have some state as well (font,fontsize,justification,...), but the average user might be happy enough just setting the title to a string and being done with it ... One way to accomplish this would be to: class Title(object): def __init__(self,text,font='times',size=12): self.text = text self.font = font self.size = size def __call__(self,*text,**kwargs): if(text): self.text = text[0] for k,v in kwargs.items(): setattr(self,k,v) def __str__(self): return '<title font={font}, size={size}>{text}</title>'.format(text=self.text,size=self.size,font=self.font) class Document(object): _special_attr = set(['title']) def __setattr__(self,k,v): if k in self._special_attr and hasattr(self,k): getattr(self,k)(v) else: object.__setattr__(self,k,v) def __init__(self,text="",title=""): self.title = Title(title) self.text = text def __str__(self): return str(self.title)+'<body>'+self.text+'</body>' Now I can use this as follows: doc = Document() doc.title = "Hello World" print (str(doc)) doc.title("Goodbye World",font="Helvetica") print (str(doc)) This implementation seems a little messy though (with __special_attr). Maybe that's because this is a messed up API. I'm not sure. Is there a better way to do this? Or did I leave the beaten path a little too far on this one? I realize I could use @property for this as well, but that wouldn't scale well at all if I had more than just one attribute which is to behave this way -- I'd need to write a getter and setter for each, yuck.

  • Page_Load or Page_Init

    - by balexandre
    Let's take a really simple example on using jQuery to ajaxify our page... $.load("getOrders.aspx", {limit: 25}, function(data) { // info as JSON is available in the data variable }); and in the ASP.NET (HTML part) page (only one line) <%@ Page Language="C#" AutoEventWireup="true" CodeFile="getOrders.aspx.cs" Inherits="getOrders" %> and in the ASP.NET (Code Behind) page public partial class getOrders : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { string lmt = Request["limit"]; List<Orders> ords = dll.GetOrders(limit); WriteOutput( Newtonsoft.Json.JsonConvert.SerializeObject(ords) ); } private void WriteOutput(string s) { Response.Clear(); Response.Write(s); Response.Flush(); Response.End(); } } my question is Should it be protected void Page_Load(object sender, EventArgs e) or protected void Page_Init(object sender, EventArgs e) So we can save some milliseconds as we don't actually need to process the events for the page, or will Page_Init lack of some sorting of a method by the time it is called? P.S. Currently works fine in both methods, but I just want to understand the ins and outs of choosing one method over the other

  • TreeView Control Problem

    - by ProgNet
    Hi all, I have a public folder on the server that contains recursively nested sub folders. In the various Leaf folders contains Images. I wanted to create a server side file browser that will display the Images to the user. I am using the ASP.NET TreeView Control. I create the tree nodes using PopulateOnDemand. If the user click on a leaf directory I want the images in that folder to be displayed in a DataList Control. The problem is that when I click on a sub tree node (after I expanded it parent node) All the expanded sub tree disappears and only the parent node is showed with no + sign next to it !! ( I have set the TreeView's PopulateNodesFromClient property to true ) Can someone tell me what is the problem ?? Thanks Here is the code : <asp:TreeView ID="TreeView1" runat="server" AutoGenerateDataBindings="False" onselectednodechanged="TreeView1_SelectedNodeChanged" ontreenodepopulate="TreeView1_TreeNodePopulate"> </asp:TreeView> protected void Page_Load(object sender, EventArgs e) { if (!Page.IsPostBack) { string path = Server.MapPath("."); PopulateTopNodes(path); } } private void PopulateTopNodes(string pathToRootFolder) { DirectoryInfo dirInfo = new DirectoryInfo(pathToRootFolder); DirectoryInfo[] dirs = dirInfo.GetDirectories(); foreach (DirectoryInfo dir in dirs) { TreeNode folderNode = new TreeNode(dir.Name,dir.FullName); if (dir.GetDirectories().Length > 0) { folderNode.PopulateOnDemand = true; folderNode.Collapse(); } TreeView1.Nodes.Add(folderNode); } } protected void TreeView1_TreeNodePopulate(object sender, TreeNodeEventArgs e) { if (IsCallback == true) { if (e.Node.ChildNodes.Count == 0) { LoadChildNode(e.Node); } } } private void LoadChildNode(TreeNode treeNode) { DirectoryInfo dirInfo = new DirectoryInfo(treeNode.Value); DirectoryInfo[] dirs = dirInfo.GetDirectories(); foreach (DirectoryInfo dir in dirs) { TreeNode folderNode = new TreeNode(dir.Name, dir.FullName); if(dir.GetDirectories().Length>0){ folderNode.PopulateOnDemand = true; folderNode.Collapse(); } treeNode.ChildNodes.Add(folderNode); } } protected void TreeView1_SelectedNodeChanged(object sender, EventArgs e) { // Retrieve the images here }

  • Lookback API: How long is a defect in a particular state?

    - by user1195996
    We have a state in our defects called "Need More Information". I would like to create a graph over time of how many defects are in that state at any particular period of time. I think I can get the info to do that with the Lookback API with the following query: my $find = { State => 'Need More Information', '_PreviousValues.State' => {'$ne' => 'Need More Information'}, _TypeHierarchy => -51006, # defect _ValidFrom => { '$gte' => '2012-09-01TZ', '$lt' => '2012-10-23TZ', } I thought that would give me back a list of all defect snapshots where the defect was transitioning into "Need More Information" state, but it does not (seems to list everything that was ever in "Need More Information" state. Technically what I need is a query that lists snapshots of any defects transitioning either TO OR FROM the "Need More Information" state, but since this simpler one did not seem to work as I expected, I thought I would ask first why the query above did not work the way I expected.

  • Printing the "source" class in a log statement with a log4j wrapper

    - by Dur4ndal
    My application has a homebrew logging class that I'm migrating to using log4j under the covers. However, since I'm using the homebrew class to pass the rest of the application's logging statements to log4j, the output statements are logged as coming from the wrapper class instead of the source class. Is there a way to ensure that the "correct" source is being shown besides creating new org.apache.log4j.Logger instances for every log statement? I've also tried using the Logger.log(String callerFQCN, Priority level, Object message, Throwable t) method, but it doesnt seem to be working, for example: public class Logger2 { public static org.apache.log4j.Logger log4JLogger = org.apache.log4j.Logger.getLogger(Logger2.class); public static void warning(Object source, String message) { log(source, message, Level.WARN, null) } private static void log(Object source, String message, Level level, Throwable t) { String className = source.getClass().getName(); System.out.println("Logging class should be " + className); log4JLogger.log(className, loggingLevel, message, t); } } When called by: public void testWarning() { Logger2.warning(new Integer(3), "This should warn"); } Prints: Logging class should be java.lang.Integer 2010-05-25 10:49:57,152 WARN test.Logger2 - This should warn

  • .NET Embedded Manifest Crashes XP

    - by Alan Spark
    Hi, I am embedding a manifest in a .NET exe so that it can request elevated permissions in Vista and Windows 7. The manifest that I am using is as follows: <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0"> <assemblyIdentity version="1.0.0.0" name="ElevationTest" type="win32"/> <trustInfo xmlns="urn:schemas-microsoft-com:asm.v3"> <security> <requestedPrivileges> <requestedExecutionLevel level="requireAdministrator"/> </requestedPrivileges> </security> </trustInfo> </assembly> It works as expected in Vista and Windows 7 but crashes XP with the standard "... has encountered a problem and needs to close..." error. If I don't embed any manifest then it works as expected but will obviously not have the required permissions in Vista and Windows 7. What is a standard way of producing an exe that will function with the correct permissions in XP and Vista / Windows 7? Thanks, Alan

  • Visual C++ function suddenly 170 ms slower (4x longer)

    - by Mikael
    For the past few months I've been working on a Visual C++ project to take images from cameras and process them. Up until today this has taken about 65 ms to update the data but now it has suddenly increased significantly. What happens is: I launch my program and for the first 30 or so iterations it performs as expected, then suddenly the loop time increases from 65 ms to 250 ms. The odd thing is, after timing each function I found out that the part of the code which is causing the slowdown is fairly basic and has not been modified in over a month. The data which goes into it is unchanged and identical every iteration but the execution time which is initially less than 1 ms suddenly increases to 170 ms while the rest of the code is still performing as expected (time-wise). Basically, I am calling the same function over and over, for the first 30 calls it performs as it should, after that it slows down for no apparent reason. It might also be worth noting that it is a sudden change in execution time, not a gradual increase. What could be causing this? The code is leaking some memory (~50 kb/s) but not nearly enough to warrant a sudden 4x slowdown. If anyone has any ideas I'd love to hear them!

  • Dependency injection in C++

    - by Yorgos Pagles
    This is also a question that I asked in a comment in one of Miško Hevery's google talks that was dealing with dependency injection but it got buried in the comments. I wonder how can the factory / builder step of wiring the dependencies together can work in C++. I.e. we have a class A that depends on B. The builder will allocate B in the heap, pass a pointer to B in A's constructor while also allocating in the heap and return a pointer to A. Who cleans up afterwards? Is it good to let the builder clean up after it's done? It seems to be the correct method since in the talk it says that the builder should setup objects that are expected to have the same lifetime or at least the dependencies have longer lifetime (I also have a question on that). What I mean in code: class builder { public: builder() : m_ClassA(NULL),m_ClassB(NULL) { } ~builder() { if (m_ClassB) { delete m_ClassB; } if (m_ClassA) { delete m_ClassA; } } ClassA *build() { m_ClassB = new class B; m_ClassA = new class A(m_ClassB); return m_ClassA; } }; Now if there is a dependency that is expected to last longer than the lifetime of the object we are injecting it into (say ClassC is that dependency) I understand that we should change the build method to something like: ClassA *builder::build(ClassC *classC) { m_ClassB = new class B; m_ClassA = new class A(m_ClassB, classC); return m_ClassA; } What is your preferred approach?

  • Rails RESTful routs without #new, rspec trouble

    - by pdkl95
    I'm currently writing a Rails app, and hit a somewhat strange quirk. I have a controller PermissionsController, which is mainly for display purposes at the moment. So my routing is locked down: map.resources :permissions, :only => [:index, :show] Unfortunately, when writing the tests, one of the routing tests fails: it "does not recognize #new" do { :get => "/permissions/new" }.should_not be_routable end with the error: Expected 'GET /permissions/new' to fail, but it routed to {"action"=>"show", "id"=>"new", "controller"=>"permissions"} instead Obviously, the #show action's route is matching with /permissions/:id, which also gives the expected error Couldn't find Permission with ID=new if you actually browse to that URL. This is not a serious error, as it is correctly raising an exception with the bad :id parameter, but it's kind of ugly. Is there any way to actually make Rails reject that route? Some trick in the routing options that I'm missing? I suppose I should just leave that test out and ignore it, or maybe remove the whole RESTful idea altogether and go back to a simpler map.connect 'permissions/:id' style. I strongly suspect I'll be expanding this in the future, though, and kind of wanted to keep my controllers consistent with each other. Just having to add occasional :only or :except rules made routes.rb nice and clean...

  • Is this a good way to generically deserialize objects?

    - by Damien Wildfire
    I have a stream onto which serialized objects representing messages are dumped periodically. The objects are one of a very limited number of types, and other than the actual sequence of bytes that arrives, I have no way of knowing what type of message it is. I would like to simply try to deserialize it as an object of a particular type, and if an exception is thrown, try again with the next type. I have an interface that looks like this: public interface IMessageHandler<T> where T : class, IMessage { T Handle(string message); } // elsewhere: // (These are all xsd.exe-generated classes from an XML schema.) public class AppleMessage : IMessage { ... } public class BananaMessage : IMessage { ... } public class CoconutMessage : IMessage { ... } Then I wrote a GenericHandler<T> that looks like this: public class GenericHandler<T> : IMessageHandler<T> where T: class, IMessage { public class MessageHandler : IMessageHandler { T IMessageHandler.Handle(string message) { T result = default(T); try { // This utility method tries to deserialize the object with an // XmlSerializer as if it were an object of type T. result = Utils.SerializationHelper.Deserialize<T>(message); } catch (InvalidCastException e) { result = default(T); } return result; } } } Two questions: Using my GenericHandler<T> (or something similar to it), I'd now like to populate a collection with handlers that each handle a different type. Then I want to invoke each handler's Handle method on a particular message to see if it can be deserialized. If I get a null result, move onto the next handler; otherwise, the message has been deserialized. Can this be done? Is there a better way to deserialize data of unknown (but restricted) type?
