• Why my custom CStatic derived control does not receive WM_SIZE message?

  - by Michael P

  Hello everyone! I'm currently developing a custom control that derives from CStatic MFC class (Smart Device C++ project). I have created the control class using VC++ MFC class wizard, selecting CStatic class as its base class. I have used Class View to add OnSize event handler for my control class (I have selected WM_SIZE message from messages list), and new OnSize method has been created by Visual Studio along with ON_WM_SIZE() statement between BEGIN_MESSAGE_MAP(...) and END_MESSAGE_MAP(). The problem is that my control does not receive WM_SIZE thus OnSize method is never called - I used MoveWindow to change size of my control - its size changes as I have seen on dialog window but WM_SIZE message is never being sent. When I send WM_SIZE through SendMessage or PostMessage function - the control OnSize method is called normally. What do I wrong? I've read MSDN docs about CStatic control and there is no information that WM_SIZE message is never sent to a static control window. Sorry for my bad English.

  When an user tries to send AJAX requests simultaneously from multiple browser tabs, the earlier requests get completed and the page loads but the other AJAX calls are preempted. AS a result of which the response is empty for the other calls. Only one call survives. In my application using struts 2.0, JSP and javascript and the prototype framework, i found that the server response is empty in the cases mentioned above though the data gets updated in teh database with the request parameters. The onSucess event handler for Ajax.request gets called but the the response is empty. Can you please help? Thanks

• Is ASP.Net Server Control, Postback Architecture failed in current Web 2.0 World.

  - by Lalit

  What i am looking around me is the drastically change in ASP.Net Architecture. More and more company are following the approach of JSON based wcf service in middle tier. Plain HTML based UI tier with JQuery/Ajax. No Postback at all, This contradicts the Default behaviour of Asp.Net Server Control/Code Behind Event handler/Postback. I am a Asp.Net Web Developer for around 4 years, and concerned about the future of ASP.Net. Is the Default Architecture of ASP.Net is Outdated at all? Does MVC or ASP.Net 4.0 Tries to solve the Issue?

  I have a scenario where I should redirect my Legacy Url to my current SEO Url. and I have 300+ different legacy urls so I am handling all those in my 404 Handler. I have my Legacy Url and the actual Action, controller and parameters it is supposed to use. But the issue is there is already a SEO friendly route for these Action and Controller. so I want to redirect this legacy URL to that friendly route. So I am planning to generate a link like what Html.ActionLink does and want to move permanently. Can anyone help me in generating this link???

• Implement keyboard control in JavaScript Grid

  - by Vanco

  I finished building a JavaScript grid control, end everything works fine. Paging, button navigation, column sorting, etc. The cells in the grid are DIVs which are generated using Mootools 1.2.4 (which is heavily used throughout the control). I want to implement keyboard control for the grid, both for paging (page up/page down) and for moving with arrow keys inside the rows/cells of the grid. I think that I have to attach an event handler on each cell of the grid and detect what key is being pressed in order to take an appropriate action. But, I can't set the focus on the cells. What am I missing? How do I do this? Any help is appreciated.

• How can I dynamically inject code into event handlers in Delphi?

  - by mjustin

  For debugging / performance tests I would like to dynamically add logging code to all event handlers of components of a given type. For example, for all Dataset components located ona TDatamodule, I would like to add some code for the BeforeOpen and the AfterOpen event to store the start and end time and send a line to a logger with the elapsed time in the AfterOpen event. I would prefer to do this dynamically (no component subclassing), so that I can add this to all existing datamodules and forms with minimal effort only when needed. Iterating all components and filtering by their type is easy, but for the components which already have event handlers assigned, I need a way to store the existing event handlers, and assign a new modified event handler which first does the logging and then will invoke the original code which was already present. Is there a design pattern which can be applied, or even some example code which shows how to implement this in Delphi?

• GWT removeHandler on first event notification

  - by Keith

  I want to remove a GWT event handler the first time I receive an event. I also want to avoid polluting my class with tracking registration objects that aren't really necessary. I currently have it coded as: final HandlerRegistration[] registrationRef = new HandlerRegistration[1]; registrationRef[0] = dialog.addFooHandler(new FooHandler() { public void onFoo(FooEvent event) { HandlerRegistration removeMe = registrationRef[0]; if(removeMe != null) { removeMe.removeHandler(); } // do stuff here } }); but the use of registrationRef makes the code less readable. Is there a better way to do this without adding variables to my class?

• Will the URL /nosuchpage get routed via my ASP.NET MVC application?

  - by Gary McGill

  [I'm trying to figure out the reason why I'm having another problem, and this question is part of the puzzle.] I have an MVC 2 website that has routing set up so that URLs such as /Customer/23/Order/47 get handled by various controllers. I do not have a rule that would match, for example, /nosuchpage and in my Cassini environment a request for that URL will trigger my Application_Error code, which lets me log the error and show a friendly response. However, when I deployed this website on IIS7 using integrated mode, my Application_Error is not triggered, and IIS shows its own 404 message. No matter what I've tried, I can't get Application_Error to fire. Now I'm thinking: is the reason it doesn't fire because the request is not getting routed via my application? Either because I didn't explicitly set up a catch-all route, or because the file-extension fools it into thinking it should use the "static file handler" (whatever that is)? Should I expect my Application_Error to be invoked?

• How to pass an event to a method and then subscribe to it?

  - by Ryan Peschel

  Event Handler public void DeliverEvent(object sender, EventArgs e) { } #1: This Works public void StartListening(Button source) { source.Click += DeliverEvent; } #2: And so does this.. public void StartListening(EventHandler eventHandler) { eventHandler += DeliverEvent; } But in #2, you cannot call the method because if you try something like this: StartListening(button.Click); You get this error: The event 'System.Windows.Forms.Control.Click' can only appear on the left hand side of += or -= Is there any way around that error? I want to be able to pass the event and not the object housing the event to the StartListening method.

• C# progress bar not synced with download (WebClient class)

  - by dominiquel

  Hi, I am coding a system which has a small FTP module included inside, it's not the main feature at all, but needed... I must link the progressbar with the WebClient class event DownloadProgressChangedEventHandler and AsyncCompletedEventHandler, the progressbar increment is ok, and the ASyncCompletedEventHandler launch a MessageBox (as intended), the problem is that the progress bar see to load too slow... problem : My MessageBox pop at 100% (launched by the event handler), BUT when the MessageBox pop my progress bar is only at +-80% (but the .VALUE is really 100), the first though I had was that they have added a "smooth" effect in Windows Vista which slow down the progressbar relatively to it's true value. If any of you have experienced the same problem thanks for your help.

• How can I process a form's events in another class / module automatically in VB.NET

  - by CowKingDeluxe

  Here's my code: Public Class Form1 End Class Public Class Form1Handler Inherits Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click MsgBox("I") End Sub End Class I'm trying to get Form1Handler to process Form1's events automatically. How can I do this? Should I use a module instead? I'm doing this in VB 2010. I don't want to have to make an event handler in Form1 and then pipe it to the other class / module, is there some way to automatically "pipe" the events from form1 to form1handler?

• extjs4 display tooltip on button click instead of mouse hover

  - by user856753

  I am trying to add a on click listener to the below tooltip. I do not want the tooltip to display on mouse hover. Instead it need it show on button click. Do I have to add a handler function inside a listener? { xtype: 'button', cls:'my-btn', iconCls:'question', src:'../www/css/slate/btn/question.png', padding: '5 0 0 0', listeners: { render: function(cmp) { Ext.create('Ext.tip.ToolTip', { closable:true, hideDelay : 3000, padding: '0 0 0 0', maxWidth:400, width:800, target: cmp.el, html: "<b>read-only</b>:Users will have read only access to all pages", getTargetXY: function() { return [810, 340]; } }); } } },

• jQuery TriggerHandler doesn't trigger keyup event set via live

  - by Beck

  Why i can't trigget handler via triggerHandler if it's was bound via live? For example form.find('#code').live('change keyup',function(){ process_code($(this)); }); Startups after window load: /* Triggers */ if(checkCookie('banner_ready_code')) { $('#form').find('#code').triggerHandler('keyup'); } Nothing happens... If i'm binding simply by .change or .keyup, triggerHandler is working properly as intended. If it's bug, where to report it. Too lazy :) If not, please explain. :)

• UrlRewriter.Net with URL with final dot

  - by devio

  I want to use UrlRewriter.Net as described in this blog by ScottGu. In the example below, page.aspx should display a page text stored in the database based on the title= URL parameter. After a couple of tweaks the only remaining issue seems to be that a final dot in the URL causes a 404 a sequence of two dots in the URL causes a 400 Windows 7, IIS 7 with Integrated AppPool, VS2008. Looking at the Failed Request Log, it seems that the UrlRewriter module is called after retrieving the request handler. Can these two issues be fixed, or is there a better replacement for UrlRewriter? (A related question only asks about the 404) Edit: This behavior can even be reproduced on SO, so maybe there is no work-around?

• How to programmatically set a data cell of database in VB.Net?

  - by manuel

  I have a Microsoft Access database file connected to VB.NET. In the database table, I have a 'No.' and a 'Status' column. Then I have a textbox where I can input an integer. I also have a button, which will change the data cell in 'Status' where 'No.' = textbox.Text(), when I click it. Let's say I want the 'Status' cell to be changed to "Low". What codes should I put in the button_Click event handler? Here is the codes I used to retrieve and display the database table. Public Class theForm Dim con As New OleDb.OleDbConnection Dim ds As New DataSet Dim daTitles As OleDb.OleDbDataAdapter Private Sub theForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load con.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=|DataDirectory|\db1.mdb" con.Open() daTitles = New OleDb.OleDbDataAdapter("SELECT * FROM Titles", con) daTitles.Fill(ds, "Titles") DataGridView1.DataSource = ds.Tables("Titles") DataGridView1.AutoResizeColumns() End Sub

• WCF extensions without including the assembly version

  - by Marc Gravell

  As discussed here, I'm trying to add a WCF endpoint-extension; I've got it working, but I need to include the full assembly details: <extensions> <behaviorExtensions> <add name="protobuf" type="ProtoBuf.ServiceModel.ProtoBehaviorExtension, protobuf-net, Version=1.0.0.275, Culture=neutral, PublicKeyToken=257b51d87d2e4d67"/> </behaviorExtensions> </extensions> What I would like to do (to avoid issues when updating etc, especially for samples) is to include just the names: <add name="protobuf" type="ProtoBuf.ServiceModel.ProtoBehaviorExtension, protobuf-net"/> (which is what you might expect from standard assembly-naming conventions) However, if I do this, I get a big error: Parser Error Message: An error occurred creating the configuration section handler for system.serviceModel/behaviors: Extension element 'protobuf' cannot be added to this element. Verify that the extension is registered in the extension collection at system.serviceModel/extensions/behaviorExtensions. Is it possible (and if so: how) to add an extension without having to specify the assembly-version?

• How to use a CTabCtrl in a MFC dialog based application ?

  - by shan23

  I need to do something which i expected to be was simple - create a tab control which has 2 tabs, implying 2 modes of operation for my app. When user clicks on Tab1, he'll be presented with some buttons and textboxes, and when he clicks Tab2, some other input method. I noticed that there was a CTabCtrl class thats used in MFC to add tabs. However, once I added the tab ctrl using the UI designer, I couldn't specify how many tabs there'll be using property window. Searching on the net, I found some examples but all of them required you to derive from CtabCtrl , create 2 or more child dialogs etc and to write your own custom class. My question is, since I want to do something so basic, why couldn't I do it using the familiar Add Event handler/Add member variable wizard and then handle everything else inside my app's class ? Surely, the default CTabCtrl class can do something useful without needing to derive from it ?

• Storing uploaded content on a website

  - by Matt

  For the past 5 years, my typical solution for storing uploaded files (images, videos, documents, etc) was to throw everything into an "upload" folder and give it a unique name. I'm looking to refine my methods for storing uploaded content and I'm just wondering what other methods are used / preferred. I've considered storing each item in their own folder (folder name is the Id in the db) so I can preserve the uploaded file name. I've also considered uploading all media to a locked folder, then using a file handler, which you pass the Id of the file you want to download in the querystring, it would then read the file and send the bytes to the user. This is handy for checking access, and restricting bandwidth for users.

• Deferring signal handling in Linux

  - by EpsilonVector

  I'm trying to figure out how to block a signal in Linux kernel 2.4 (user space) from invoking its handler, but keep it available to be handled later, preferably as soon as I re activate the handling of said signal. The function sigprocmask seem to come up in all my search results, but I can't find a good, clear description that explains whether the blocked signal gets "saved" to be handled later, and if so where and how do I handle it when I'm ready for it. Can someone please clarify what's going on, preferably with a code example? Thanks in advance.
