  • How to load images and fragments dynamically in LiveCycle Designer forms?

    - by John
    Hi there. I've created a couple of shared templates (.xdp) which will be shared among several clients. Obviously, each client has their own logo and I'd like to set the logo upon form generation. I've managed to change the logo dynamically although I'm not sure if my approach is good. In the xml datasource I've got this element: <ClientID>SomeNumber</ClientId> In the form itself I set the image href with this javascript code: SomeHiddenTextField::calculate HeaderLogo.value.image.href = $record.ClientID + "_logo.jpg"; I've got the logos stored on the server in the same folder as the shared templates. Is this an alright approach to load logos dynamically? I've been trying to achieve the same dynamic behaviour with each client's footer fragment, but I have been unable to figure out how to load these on demand. I could make each footer fragment in to an image but I'd like to avoid it if possible.

  • drop down list binding

    - by John
    I have a table which has an Id and a name field. I usually bind the name to the dropdownlist but I was told that any dml should be on the Id so how can I use the name in the dropdownlist and at the same time still use the Id?

  • Ajax: Load XML from different domain?

    - by John Isaacks
    I have signed up(paid) for Google site search. They have me a url of a sort of web service where I can send a query to it, it searches my site, and it returns XML of the search results. Well I am trying to load this XML via Ajax from a page on my site but I cannot. I can load from any of my pages on my domain so I am assuming it is because of the XML being on Google's domain. So there has got to be a way to load it though, I don't think they would have given me the URL if I couldn't do anything with it lol. Does anyone know how to do this? Thanks! UPDATE: this is what the page says on google that gave me the XML: How to get XML You can get XML results for your search engine by replacing query+terms with your search query in this URL: http://www.google.com/cse?cx=MY_UNIQUE_KEY&client=google-csbe&output=xml_no_dtd&q=query+terms Where MY_UNIQUE_KEY = my unique key.

  • Polling servers at the same port - Threads and Java

    - by John
    Hi there. I'm currently busy working on an IP ban tool for the early versions of Call of Duty 1. (Apparently such a feature wasn't implemented in these versions). I've finished a single threaded application but it won't perform well enough for multiple servers, which is why I am trying to implement threading. Right now, each server has its own thread. I have a Networking class, which has a method; "GetStatus" -- this method is synchronized. This method uses a DatagramSocket to communicate with the server. Since this method is static and synchronized, I shouldn't get in trouble and receive a whole bunch of "Address already in use" exceptions. However, I have a second method named "SendMessage". This method is supposed to send a message to the server. How can I make sure "SendMessage" cannot be invoked when there's already a thread running in "GetStatus", and the other way around? If I make both synchronized, I will still get in trouble if Thread A is opening a socket on Port 99999 and invoking "SendMessage" while Thread B is opening a socket on the same port and invoking "GetStatus"? (Game servers are usually hosted on the same ports) I guess what I am really after is a way to make an entire class synchronized, so that only one method can be invoked and run at a time by a single thread. Hope that what I am trying to accomplish/avoid is made clear in this text. Any help is greatly appreciated.

  • CSS- How to align background image over bottom border line? Jsfiddle included

    - by John Robinson
    I have an image I am trying to display over the top of a bottom border, but it is being arranged behind the bottom border element (in this example, named "divider"), and I can't get it to align correctly. I would like the image to be displayed in the middle of the the border element and over the top of it. Vertically, I am trying to get the 1px line on the left and right side of the image to align with the 1px border to appear as if it is one element. Here is the code: .divider { border-bottom: 1px solid #c3c3c3; clear: both; display: block; margin-bottom: 20px; padding-top: 20px; width: 100%; } .sidearrow { background: url(http://s16.postimage.org/sbf7v9n75/sidearrow.png) 50% 14px no-repeat; width: 100%; height: 25px; }? <p>Here is some content above</p> <div class="sidearrow"></div> <div class="divider"></div> <p>Here is some content below</p>? And the jsfiddle: http://jsfiddle.net/F5xjx/2/ Any ideas how to get this to work? Thanks in advance.

  • Deployment of a .NET application making use of SQL Server 2008

    - by Victor John Saliba
    I have searched the internet thoroughly for this type of issue, there were responses but hasn't really found a concrete solution yet. I have an application which makes use of SQL Server 2008 R2 and thus it makes connections with a database file which I have set up. The application executes successfully, makes connections with the database and retrieves/inserts/updates data to and fro the database. However when I come to create a deployment project i.e. a setup project, I fail to transfer my database files to other computers and make database connections. I have checked the SQL Server 2008 prerequisite in the publish settings of the application and has also included the database files. Can anyone suggest the best way to this type of setup? Thanks

  • how to separate debug and release mode code

    - by john
    during debug mode or while i am doing testing, i need to print lost of various information, so i use this method ifdef TESTING // code with lots of debugging info else // clean code only endif // TESTING` Is this the good method, or is there any other simple and elegant method. But this way, I am repating the same code in two places and if anything is to be changed later on in the code, I have to do it in both places, which is time consuming and error prone. Thanks. I am using MS Visual Studio.

  • How to reduce the need for IISRESET for developing ASP.NET web app in IIS 5.1

    - by John Galt
    I have a web application project on my dev PC running WinXP and hence IIS 5.1. The changes I'm making to this site seem to "take effect" only after I do IISRESET. That is, I make a source change, Rebuild the project and then Start without Debugging (or with debugging). The newly changed code is not "visible" or in effect unless I intervene with an IISRESET. BTW, the "web" tab on the Properties display for the web app project is configured to use the Local IIS web server at project Url: http://localhost/myVirtualDirectory ... but I've noticed the same issue when using the VStudio Dev Server (i.e. I have to stop it by visiting the taskbar tray area in order to see my source changes take effect). Is this something I can change? EDIT UPDATE: Just wanting to clear this up if possible. Two answers diverge below; not sure how to move forward. One states this is to be expected (weakness of IIS 5.1 which in turn is the best WinXP can provide). Another states this is not expected behavior (and I tend to agree since this is the first I've encounted this on the same old WinXP dev platform I've had a long time). I suspect it may be something "deep inside" the Visual Studio 2008 web app which was upgraded to this new IDE from VStudio 2002 (ASP.NET 1.1). I've tried to add comment/questions down each answer path. Thanks.

  • Why does grails use hsqldb when I ask for mysql?

    - by John
    I'm following the racetrack example from Jason Rudolph's book at InfoQ, using grails-1.2.1. I got up to the part where I was to switch from hsqldb to mysql. I think I've deleted every reference to hsqldb in the DataSource.groovy file, but I get an exception and the stack trace shows it's still using hsqldb. DataSource.groovy dataSource { boolean pooled = true String driverClassName = "com.mysql.jdbc.Driver" String url = "jdbc:mysql://localhost/dfpc2" String dbCreate = "create" String username = "dfpc2" String password = "dfpc2" dialect = org.hibernate.dialect.MySQL5InnoDBDialect } hibernate { cache.use_second_level_cache=true cache.use_query_cache=true cache.provider_class='net.sf.ehcache.hibernate.EhCacheProvider' } // environment specific settings environments { development { } test { } production { } } When I grails run-app it all starts up with no errors. I can navigate to the home page. But when I click on one of the links, I get a stack trace: java.sql.SQLException: Table not found in statement [select this_.id as id0_0_, this_.version as version0_0_, this_.name as name0_0_, this_.variant as variant0_0_ from domainObject this_ limit ?] at org.hsqldb.jdbc.Util.throwError(Unknown Source) at org.hsqldb.jdbc.jdbcPreparedStatement.<init>(Unknown Source) at org.hsqldb.jdbc.jdbcConnection.prepareStatement(Unknown Source) at dfpc2.domainObjectController$_closure2.doCall(script1269434425504953491149.groovy:13) at dfpc2.domainObjectController$_closure2.doCall(script1269434425504953491149.groovy) at java.lang.Thread.run(Thread.java:619) My mysql database shows no tables created. (I don't think groovy's connected to mysql yet.) Things I've checked: mysql-connector-java-5.1.6.jar is in lib directory. I've tried grails clean I tried putting the dataSource info in the development environment (I haven't graduated to test or prod yet), but it seemed to make no difference. The stdout shows I'm using development env. I've googled for solutions, but the only solution I've found is when people don't change the test or production environments.

  • How to create commandlink programmatically

    - by John
    Hi, We have a system built on seam/richfaces. There's this webpage where the tables are rendered from dynamic context (from multiple different datasources, and each of them uses a different layout to represent essentially the same real world concept). As a result, this table is binded to a bean, and it's columns/layout are generated from this bean. Now I need to add a command link on a specific column, equivalent to <a4j:commandLink value="#{actBean.Ids}" action="#{actBean.genDetails}"> <f:setPropertyActionListener target="#{actBean.Ref}" value="#{cont}"/> </a4j:commandLink> in a JSF page. My question is, how do I do this programmatically? Thanks!

  • C++ How do I properly use getline for ifstream members.

    - by John
    Ok so I have a problem with getline. I have a file that contains a couple strings. I created it by myself and I have each string on a seperate line. Ex. textfile.txt Line 1 Line 2 Line 3 Line 4 //Little snip of code ifstream inFile("textfile.txt"); getline(inFile, string1); When I debug the program and ask it to print out string1 it shows that "Line 1\r" is saved into string1. I understand that it's from me actually hitting enter when I created the file. This problem causes my program to have a segmentation fault. I know my code works because if I use ofstream to write the file first and then i read it in, it works. So for my quesiton, is their anyway to use the getline function without it picking up the escape sequence \r? If i am not clear just let me know.

  • Javascript Split: without losing character

    - by Rohan
    I want to split certain text using JavaSscript. The text looks like: 9:30 pm The user did action A. 10:30 pm Welcome, user John Doe. 11:30 am Messaged user John Doe Now, I want to split the string into events. i.e.: 9:30 pm The user did action A. would be one event. I'm using RegEx for this: var split = journals.split(/\d*\d:/); Thing is, the first two characters are getting lost. The split appears like this: 30 pm The user did action A. How do I split so that the split maintains the first two/three characters (ie 9: or 10:) etc? Thanks!

  • Change user control appearance based on state

    - by John
    I have a user control that consists of four overlapping items: 2 rectangles, an ellipse and a lable <UserControl x:Class="UserControl" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Width="50.1" Height="45.424" Background="Transparent" FontSize="24"> <Grid> <Grid.RowDefinitions> <RowDefinition Height="3.303*" /> <RowDefinition Height="40*" /> <RowDefinition Height="2.121*" /> </Grid.RowDefinitions> <Grid.ColumnDefinitions> <ColumnDefinition Width="5.344*" /> <ColumnDefinition Width="40.075*" /> <ColumnDefinition Width="4.663*" /> </Grid.ColumnDefinitions> <Rectangle Name="Rectangle1" RadiusX="5" RadiusY="5" Fill="DarkGray" Grid.ColumnSpan="3" Grid.RowSpan="3" /> <Ellipse Name="ellipse1" Fill="{Binding State}" Margin="0.016,0.001,4.663,0" Grid.Row="1" Grid.Column="1" Grid.ColumnSpan="2" Stroke="Black" IsEnabled="True" Panel.ZIndex="2" /> <Label Name="lblNumber" HorizontalContentAlignment="Center" VerticalContentAlignment="Center" Foreground="White" FontWeight="Bold" FontSize="24" Grid.Column="1" Grid.Row="1" Padding="0" Panel.ZIndex="3">9</Label> <Rectangle Grid.Column="1" Grid.Row="1" Margin="0.091,0,4.663,0" Fill="Blue" Name="rectangle2" Stroke="Black" Grid.ColumnSpan="2" Panel.ZIndex="1" /> </Grid> Here is my business object that I want to control the state of my user control: Imports System.Data Imports System.ComponentModel Public Class BusinessObject Implements INotifyPropertyChanged 'Public logger As log4net.ILog Public Event PropertyChanged As PropertyChangedEventHandler Implements INotifyPropertyChanged.PropertyChanged Private _state As States Public Enum States State1 State2 State3 End Enum Public Property State() As States Get Return _state End Get Set(ByVal value As States) If (value <> _state) Then _state = value RaiseEvent PropertyChanged(Me, New PropertyChangedEventArgs("State")) End If End Set End Property Protected Sub OnPropertyChanged(ByVal name As String) RaiseEvent PropertyChanged(Me, New PropertyChangedEventArgs(name)) End Sub I want to be able to change the state of a business object in the code behind and have that change the colors of multiple shapes in my usercontrol. I'm not sure about how to do the binding. I set the datacontext of the user control in the code behind but not sure if that's right. I'm new to WPF and programming in general and I'm stuck on where to go from here. Any recommendations would be greatly appreciated!!

  • Rails: unexpected behavior updating a shared instance

    - by Pascal Lindelauf
    I have a User object, that is related to a Post object via two different association paths: Post --(has_many)-- comments --(belongs to)-- writer (of type User) Post --(belongs to)-- writer (of type User) Say the following hold: user1.name == "Bill" post1.comments[1].writer == user1 post1.writer == user1 Now when I retrieve the post1 and its comments from the database and I update post1.comments[1].writer like so: post1.comments[1].writer.name = "John" I would expect post1.writer to equal "John" too. But it doesn't! It still equals "Bill". So there seems to be some caching going on, but the kind I would not expect. I would expect Rails to be clever enough to load exactly one instance of the user with name "Bill"; instead is appears to load two individual ones: one for each association path. Can someone explain how this works exactly and how I am to handle these types of situations the "Rails way"?

  • Easiest way to convert json data into objects with methods attached?

    - by John Mee
    What's the quickest and easiest way to convert my json, containing the data of the objects, into actual objects with methods attached? By way of example, I get data for a fruitbowl with an array of fruit objects which in turn contain an array of seeds thus: {"fruitbowl": [{ "name": "apple", "color": "red", "seeds": [] },{ "name": "orange", "color": "orange", "seeds": [ {"size":"small","density":"hard"}, {"size":"small","density":"soft"} ]} } That's all nice and good but down on the client we do stuff with this fruit, like eat it and plant trees... var fruitbowl = [] function Fruit(name, color, seeds){ this.name = name this.color = color this.seeds = seeds this.eat = function(){ // munch munch } } function Seed(size, density){ this.size = size this.density = density this.plant = function(){ // grow grow } } My ajax's success routine currently is currently looping over the thing and constructing each object in turn and it doesn't handle the seeds yet, because before I go looping over seed constructors I'm thinking Is there not a better way? success: function(data){ fruitbowl.length = 0 $.each(data.fruitbowl, function(i, f){ fruitbowl.push(new Fruit(f.name, f.color, f.seeds)) }) I haven't explored looping over the objects as they are and attaching all the methods. Would that work?
