  • Button.MouseDown

    - by Gilad
    Hi Guys, I'm relatively new with WPF. I'm trying to understand the difference between MouseDownEvent and PreviewMouseDownEvent. I understand the WPF event strategies and i understand that the MouseDown event is a bubbling event and the PreviewMouseDown is a tunneling event. I also understand the order of which these events are being fired - according to this MSDN overview http://msdn.microsoft.com/en-us/library/ms742806.aspx#routing (there is a diagram with example there). So i tried to code some my self, check this for example: <Grid x:Name="grid" Width="250"> <StackPanel Mouse.MouseDown="StackPanel_MouseDown" PreviewMouseDown="StackPanel_PreviewMouseDown"> <WPFVisualizerExample:MyButton x:Name="B1" PreviewMouseDown="B1_PreviewMouseDown" MouseDown="B1_MouseDown" Margin="5,5,5,5"> <WPFVisualizerExample:MyButton x:Name="B2" PreviewMouseDown="B2_PreviewMouseDown" MouseDown="B2_MouseDown" Margin="5,5,5,5"> <WPFVisualizerExample:MyButton x:Name="B3" PreviewMouseDown="B3_PreviewMouseDown" MouseDown="B3_MouseDown" Margin="5,5,5,5">Click Me</WPFVisualizerExample:MyButton> </WPFVisualizerExample:MyButton> </WPFVisualizerExample:MyButton> </StackPanel> </Grid> I have an event handler for each of the events (the preview and non-preview) and i wanted to see what is happening, which of the event is being thrown (i have a message box shown for each event). The 'MyButton' user control simply extends the base Button and override the OnMouseDown and OnPreviewMouseDown to set the e.Handled false: protected override void OnMouseDown(System.Windows.Input.MouseButtonEventArgs e) { base.OnMouseDown(e); e.Handled = false; } protected override void OnPreviewMouseDown(System.Windows.Input.MouseButtonEventArgs e) { base.OnPreviewMouseDown(e); e.Handled = false; } (tried with this and without this). According to the MSDN overview (in the link above), if i have 3 elements then the events route should be as follows: PreviewMouseDown (tunnel) on root element. PreviewMouseDown (tunnel) on intermediate element #1. PreviewMouseDown (tunnel) on source element #2. MouseDown (bubble) on source element #2. MouseDown (bubble) on intermediate element #1. MouseDown (bubble) on root element. So I expected the the message boxes to be shown according to the above. From some reason - which I don't understand only the preview events are being thrown (according to what the MSDN says Preview_B1=Preview_B2=Preview_B3). My expectations were: Preview_B1=Preview_B2=Preview_B3=NonPreview_B3=NonPreview_B2=NonPreview_B1. But the non-preview events are not being thrown at all. So basically I don't understand the route of the events, from MSDN overview I understood that the route starts from the root element, goes down (tunnel) to the source element and then back up (bubble) to the root element, but this is not what happening in practice. It is really important for me to understand how this events are working, i probably miss-understand something basic here, your help will be appreciated. THANX!! -Gili

  • Putting update logic in your migrations

    - by Daniel Abrahamsson
    A couple of times I've been in the situation where I've wanted to refactor the design of some model and have ended up putting update logic in migrations. However, as far as I've understood, this is not good practice (especially since you are encouraged to use your schema file for deployment, and not your migrations). How do you deal with these kind of problems? To clearify what I mean, say I have a User model. Since I thought there would only be two kinds of users, namely a "normal" user and an administrator, I chose to use a simple boolean field telling whether the user was an adminstrator or not. However, after I while I figured I needed some third kind of user, perhaps a moderator or something similar. In this case I add a UserType model (and the corresponding migration), and a second migration for removing the "admin" flag from the user table. And here comes the problem. In the "add_user_type_to_users" migration I have to map the admin flag value to a user type. Additionally, in order to do this, the user types have to exist, meaning I can not use the seeds file, but rather create the user types in the migration (also considered bad practice). Here comes some fictional code representing the situation: class CreateUserTypes < ActiveRecord::Migration def self.up create_table :user_types do |t| t.string :name, :nil => false, :unique => true end #Create basic types (can not put in seed, because of future migration dependency) UserType.create!(:name => "BASIC") UserType.create!(:name => "MODERATOR") UserType.create!(:name => "ADMINISTRATOR") end def self.down drop_table :user_types end end class AddTypeIdToUsers < ActiveRecord::Migration def self.up add_column :users, :type_id, :integer #Determine type via the admin flag basic = UserType.find_by_name("BASIC") admin = UserType.find_by_name("ADMINISTRATOR") User.all.each {|u| u.update_attribute(:type_id, (u.admin?) ? admin.id : basic.id)} #Remove the admin flag remove_column :users, :admin #Add foreign key execute "alter table users add constraint fk_user_type_id foreign key (type_id) references user_types (id)" end def self.down #Re-add the admin flag add_column :users, :admin, :boolean, :default => false #Reset the admin flag (this is the problematic update code) admin = UserType.find_by_name("ADMINISTRATOR") execute "update users set admin=true where type_id=#{admin.id}" #Remove foreign key constraint execute "alter table users drop foreign key fk_user_type_id" #Drop the type_id column remove_column :users, :type_id end end As you can see there are two problematic parts. First the row creation part in the first model, which is necessary if I would like to run all migrations in a row, then the "update" part in the second migration that maps the "admin" column to the "type_id" column. Any advice?

  • How to generate a certificate request with SubjectAltNames on IIS 6.0 ?

    - by Gumble
    I'm looking for a way to add a Subject Alternative Name in my certificate request in the IIS 6.0 certificate creation wizard. It seems I can only fill the Subject field and not the Subject Alternative Name. Trying to follow this guide (http://support.microsoft.com/kb/931351) using certreq.exe doesn't help, it fails without any hint except that it prints its manual. Any suggestions appreciated, I hope I won't have to export my public key and generate the csr with openssl :/

  • validation in javascript - remove the error msg on focus

    - by fusion
    i'm not very well-versed with javascript, so please bear with me. i've a form in which i validate the controls with javascript. the error is displayed when the fields are empty via a div, but when i focus and type something in the textbox, the div should go away. but the error div doesn't and even if i type something valid, it still displays the div. i'd like to know where am i going wrong with this script: <script type="text/javascript"> var err = document.getElementById("errmsg"); function checkInput(inPut) { if (inPut.getValue() == "") { err.setStyle('display', 'block'); err.setTextValue("Field cannot be empty!"); inPut.focus(); return false; } else { return true; } } function checkTextBox(textBox) { if (textBox.getValue() == "") { err.setStyle('display', 'block'); err.setTextValue("Field cannot be empty!"); textBox.focus(); return false; } else if (!checkValidity(textBox.getValue())) { err.setStyle('display', 'block'); err.setTextValue("Please enter a valid email address!"); textBox.focus(); return false; } else { return true; } } . . . <div id="errmsg" class="invalid" style="display:none;"></div> <br /> . . . <input type="text" tabindex="1" name="name" id="name" class="input_contact" onblur="checkInput(this);"/> <br /> . . . <input type="text" tabindex="2" name="email" id="email" class="input_contact" onblur="checkTextBox(this);"/> <br /> it's a form in facebook app but while the fbjs works, i assume there's a problem with my basic javascript.

  • Test for absence of an input tag's value attribute

    - by Jeff
    How can I confirm the absence of a HTML attribute in a Rails RSpec test? I can verify that an input tag has a value attribute and that it is an empty string like so: response.should have_tag("input[name=?][value=?]", "user[password]", "") response.should have_tag("input[name=?][value=?]", "user[password_confirmation]", "") But what I want to do is verify that my input fields do not have a value attribute at all (i.e., a blank field).

  • controlling threads flow

    - by owca
    I had a task to write simple game simulating two players picking up 1-3 matches one after another until the pile is gone. I managed to do it for computer choosing random value of matches but now I'd like to go further and allow humans to play the game. Here's what I already have : http://paste.pocoo.org/show/201761/ Class Player is a computer player, and PlayerMan should be human being. Problem is, that thread of PlayerMan should wait until proper value of matches is given but I cannot make it work this way. Logic is as follows: thread runs until matches equals to zero. If player number is correct at the moment function pickMatches() is called. After decreasing number of matches on table, thread should wait and another thread should be notified. I know I must use wait() and notify() but I can't place them right. Class Shared keeps the value of current player, and also amount of matches. public void suspendThread() { suspended = true; } public void resumeThread() { suspended = false; } @Override public void run(){ int matches=1; int which = 0; int tmp=0; Shared data = this.selectData(); String name = this.returnName(); int number = this.getNumber(); while(data.getMatches() != 0){ while(!suspended){ try{ which = data.getCurrent(); if(number == which){ matches = pickMatches(); tmp = data.getMatches() - matches; data.setMatches(tmp, number); if(data.getMatches() == 0){ System.out.println(" "+ name+" takes "+matches+" matches."); System.out.println("Winner is player: "+name); stop(); } System.out.println(" "+ name+" takes "+matches+" matches."); if(number != 0){ data.setCurrent(0); } else{ data.setCurrent(1); } } this.suspendThread(); notifyAll(); wait(); }catch(InterruptedException exc) {} } } } @Override synchronized public int pickMatches(){ Scanner scanner = new Scanner(System.in); int n = 0; Shared data = this.selectData(); System.out.println("Choose amount of matches (from 1 to 3): "); if(data.getMatches() == 1){ System.out.println("There's only 1 match left !"); while(n != 1){ n = scanner.nextInt(); } } else{ do{ n = scanner.nextInt(); } while(n <= 1 && n >= 3); } return n; } }

  • get GET parameters in JSF's managed bean

    - by mykola
    Hello! Can someone tell me how to catch parameters passed from URI in JSF's managed bean? I have a navigation menu all nodes of which link to some navigation case. And i have two similar items there: Acquiring products and Issuing products. They have the same page but one different parameter: productType. I try to set it just by adding it to URL in "to-view-id" element like this: <navigation-case> <from-outcome>acquiring|products</from-outcome> <to-view-id>/pages/products/list_products.jspx?productType=acquiring</to-view-id> </navigation-case> <navigation-case> <from-outcome>issuing|products</from-outcome> <to-view-id>/pages/products/list_products.jspx?productType=issuing</to-view-id> </navigation-case> But i can't get this "productType" from my managed bean. I tried to get it through FacesContext like this: FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap().get("productType") And like this: HttpServletRequest request = (HttpServletRequest)FacesContext.getCurrentInstance().getExternalContext().getRequest(); request.getParameter("productType"); And i tried to include it as a parameter of managed bean in faces-config.xml and then getting it through ordinary setter: <managed-bean> <managed-bean-name>MbProducts</managed-bean-name> <managed-bean-class>my.package.product.MbProducts</managed-bean-class> <managed-bean-scope>request</managed-bean-scope> <managed-property> <property-name>productType</property-name> <value>#{param.productType}</value> </managed-property> </managed-bean> ... public class MbProducts { ... public void setProductType(String productType) { this.productType = productType; } ... } But neither of these ways have helped me. All of them returned null. How can i get this productType? Or how can i pass it some other way?

  • Hosting a WCF Service Lib through a Windows service get a System.InvalidOperationException: attempti

    - by JohnL
    I have a WCF Service Library containing five service contracts. The library is hosted through a Windows Service. Most if not all my configuration for the WCF Library is declaritive. The only thing I am doing in code for configuration is to pass the type of the class implementing the service contracts into ServiceHost. I then call Open on each of the services during the Windows Service OnStart event. Here is the error message I get: Service cannot be started. System.InvalidOperationException: Service '[Fubu.Conversion.Service1' has zero application (non-infrastructure) endpoints.

  • Search for multiple values in an xml column

    - by Yuriy Gettya
    Environment: SQL Server 2012. Primary and secondary (value) index is built on xml column. Say I have a table Message with xml column WordIndex. I also have a table Word which has WordId and WordText. Xml for Message.WordIndex has the following schema: <xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema" targetNamespace="http://www.example.com"> <xs:element name="wi"> <xs:complexType> <xs:sequence> <xs:element maxOccurs="unbounded" name="w"> <xs:complexType> <xs:sequence> <xs:element maxOccurs="unbounded" name="p" type="xs:unsignedByte" /> </xs:sequence> <xs:attribute name="wid" type="xs:unsignedByte" use="required" /> </xs:complexType> </xs:element> </xs:sequence> </xs:complexType> </xs:element> </xs:schema> and some data to go with it: <wi xmlns="http://www.example.com"> <w wid="1"> <p>28</p> <p>72</p> <p>125</p> </w> <w wid="4"> <p>89</p> </w> <w wid="5"> <p>11</p> </w> </wi> I need to search for multiple values in my xml column WordIndex either using OR or AND.
