  • Unity and web service

    - by zachary
    I had this awesome idea... but I am afraid maybe it is actually a bad idea.... we use unity for dependency injection. I make interfaces from my web services using partial classes for the purpose of mocking and web services.... What I want to do is put my web services into unity and get them via dependency injection... What do you think? Is there too much overhead somewhere? Memory leaks? Is this a bad idea?

  • Image sprite not lining up in firefox

    - by Saif Bechan
    I am working with an image sprite to create my buttons. They work right in every browser except firefox. Lets say i have 2 spans next to eachother: <span class="spanleft"></span><span class="spanright"></span> and give them some styling(this is the actual code i use for the sprite) .spanleft{ background:url('/templates/default/img/auction/btn-toolbar.png') no-repeat 0 0; display:block; float:left; height:100px; width:13px; } .spanright{ background:url('/templates/default/img/auction/btn-toolbar.png') no-repeat 0 -104px; display:block; float:left; height:100px; width:30px; margin-left:0px; } Now this works in every browser i tested, the images line up great. But in firefox I get a small offset. Now i fiddled with the pixels a lot. Its not an offset of 1px, the offset is about 0.5 of a px. yeah. Ive made a screenshot of what i mean, and i'm going to put in the sprite for the buttons, they make lovely buttons, upstate,downstate,hover,disabled. You can use them in your projects. Here are the shots: This is the problem: Here is the image sprite: I hop this problem can be solved, i am working with FF 3.6. thanks guys!

  • Fast compiler error messages in Eclipse

    - by Chris Conway
    As a new Eclipse user, I am constantly annoyed by how long it takes compiler error messages to display. This is mostly only a problem for long errors that don't fit in the status bar or the "Problems" tab. But I get enough long errors in Java—especially with generics—that this is a nagging issue. (Note: The correct answer to this question is not "get better at using generics." ;-) The ways I have found to display an error are: Press Ctrl+. or execute the command "Next Annotation". The next error is highlighted and its associated message appears in the status bar (if it is short enough). The error is also highlighted in the "Problems" tab, if it is open, but the tab is not automatically brought to the top. Hover the mouse over the error. After a noticeable lag, the error message appears as a "tool tip", along with any associated "Quick Fixes." Hover the mouse over the error icon on the left side of the editing pane. After a noticeable lag, all of the error messages for that line appear as a "tool tip." Clicking on the icon brings up "Quick Fixes." What I would like is for Ctrl+. to automatically and instantly bring up the complete error message (I don't care where). Is this a configurable option? [UPDATE] @asterite's "Ctrl+. F2" is almost it. How do I make "Next Annotation, then Show Tooltip Description" a macro bound to a single keystroke?

  • ASP.Net layered communication

    - by Chris Klepeis
    Hi, We're developing a layered web application. The specs: 3 layers, data layer, business layer, ui layer. Programmed in C# Data Layer uses the entity framework Currently we plan on having the data layer return IEnumerable<T> to the business layer via linq 2 entities, and the business layer will return data to the ui layer. Since the ui layer has no knowledge of the existance of the data layer, how would it handle a result of IEnumerable passed to it from the BLL, where T is defined in the data layer? Are there any GOOD example out there on how to do this. Please note that I'm extremely new to factories / interfaces / abstraction to loosely couple layers. I saw the question here http://stackoverflow.com/questions/917457/passing-data-in-an-ntier-application and it was recommended to have the entity layer shared amongst all layers... however I do not want the other layers to be able to query the database.

  • Manually manipulating ArrayList

    - by jsan
    I have an assignment where I have to create a deque, however I am not allowed to use any built-in classes or interfaces. I am implementing my deque using an array list. My problem is that when I have to, for instance, add to the beginning of the array list (beginning of the queue), i am not allowed to do this: public void addFirst(ArrayList<Integer> array) { array.add(0, int); } Is there a way to do this without using the add() function? Such as manually adding to the front and shifting the rest of the array to the right? Or maybe creating a new array list and copying...I'm not sure. Any help would be great; I have a bunch of functions to write, and getting the first one done will definitely put me in the right direction. Thanks

  • Tool to maintain a Data Mapping between two systems

    - by ktaylorjohn
    We have XML interfaces between multiple systems. An Enterprise Domain Model is missing in the overall architecture, hence the terms Product/Customer/User means different things to different systems. We currently use excel sheets to map the elements in incoming XML to what the actual Field means within our system. Additionally, it contains the values of Mandatory/Optional and length of each field. We call this the Data Dictionary. Any changes to the XML go through rounds of deliberation and updates to Word and Excel documents. Is there a better way to do this? Any tool/GUI based approach which all systems and owners can view?

  • Duplicate information from sql result

    - by puddleJumper
    I looked in about 18 other posts on here an most people are asking how to delete the records not just hide them. So my problem: I have a database with staff members who are associated with locations. Many of the staff members are associated with more than one location. What I want to do is to only display the first location listed in the mysql result and skip over the others. I have the sql query linking the tables together and it works aside from it showing the same information for those staff members that are in those other locations multiple times so example would be like this: This is the sql statement I have currently SELECT staff_tbl.staffID, staff_tbl.firstName, staff_tbl.middleInitial, staff_tbl.lastName, location_tbl.locationID, location_tbl.staffID, officelocations_tbl.locationID, officelocations_tbl.officeName, staff_title_tbl.title_ID, staff_title_tbl.staff_ID, titles_tbl.titleID, titles_tbl.titleName FROM staff_tbl INNER JOIN location_tbl ON location_tbl.staffID = staff_tbl.staffID INNER JOIN officelocations_tbl ON location_tbl.locationID = officelocations_tbl.locationID INNER JOIN staff_title_tbl ON staff_title_tbl.staff_ID = staff_tbl.staffID INNER JOIN titles_tbl ON staff_title_tbl.title_ID = titles_tbl.titleID and my php is <?php do { ?> <tr> <td><?php echo $row_rs_Staff_Info['firstName']; ?>&nbsp; <?php echo $row_rs_Staff_Info['lastName']; ?></td> <td><?php echo $row_rs_Staff_Info['titleName']; ?>&nbsp; </td> <td><?php echo $row_rs_Staff_Info['officeName']; ?>&nbsp; </td> </tr> <?php } while ($row_mysqlResult = mysql_fetch_assoc($rs_mysqlResult)); ?> What I would like to know is there a way using php to select only the first entry listed for each person and display that and just skip over the other two. I was thinking it could be done by possibly adding the staffID's to an array and if they are in there to skip over the next one listed in the staff_title_tbl but wasn't quite sure how to write it that way. Any help would be great thank you in advance.

  • @Stateless, @Remote and @Local

    - by Jeff Foster
    In my deployment on JBoss 5.1.0GA with JavaEE-5 I have beans of the general form public interface Foo { void baz (); } @Stateless public class FooBean implements Foo { void baz() { // ... } } I have assumed that this is the same as if I have explicitly annotated the Foo interface with @Local. From seeing a stack trace in the code I think that it is actually using a remote interface, whereas I want all of my beans to be local. Do I need to explicitly annotate interfaces as Local or is there some default? Finding documentation on this is proving challenging so any links to relevant documentation would be greatly appreciated.

  • Java how does Key Event Handling Mechanism(KeyListeners notified) work ?

    - by Carbonizer
    How does application/JVM know which classes if implemented key handling interfaces ? Does it use java Reflections or does it check all the classes for methods ? How can a application or executing JVM understanding to deliver the user event or call the specific methods on a class that implemented the keylistener interface. Does it look at all the classes if those methods are implemented or how does it know which classes implmented keylistener interface ? If you dont implement the keylistener Interface for a class but still implmentation all its methods. Do the class still process the user event occurred ?

  • Image not rendering in dompdf

    - by Venkat
    I am using codeIgniter and dompdf for my application for generating pdfs. The below code is the code which i am using to display an image. <div class=\"block_head\"> <h2>Image display</h2>"; $image_location = "/images/xxx.png"; $html .="<img src=\"".$image_location."\" width=\"200\" height=\"200\" /> </div>"; I tested and debugged all ways whether i am doing something wrong. Like this first i checked whether the path is wrong. This is path on the server. It's correct. I tested by echoing $html also it's showing perfectly path. When i clicked on that path image is displaying. But when i am trying to render it in pdf it's not displaying. Note: PDF is generating perfectly without image.

  • Array of Sentences?

    - by user1869915
    Javascript noob here.... I am trying to build a site that will help my kids read predefined sentences from a select group, then when a button is clicked it will display one of the sentences. Is an array the best option for this? For example, I have this array (below) and on the click of a button I would like one of these sentences to appear on the page. <script type="text/javascript"> Sentence = new Array() Sentence[0]='Can we go to the park.'; Sentence[1]='Where is the orange cat? Said the big black dog.'; Sentence[2]='We can make the bird fly away if we jump on something.' Sentence[3]='We can go down to the store with the dog. It is not too far away.' Sentence[4]='My big yellow cat ate the little black bird.' Sentence[5]='I like to read my book at school.' Sentence[6]='We are going to swim at the park.' </script> Again, is an array the best for this and how could I get the sentence to display? Ideally I would want the button to randomly select one of these sentences but just displaying one of them for now would help. Thanks

  • Why is this one div container blocking the other from floating right?

    - by user2824289
    I know the answer is very simple, it's probably one little CSS property, but I've tried to find the solution without asking it here, no luck.. There are two div containers within a div container, and they aren't playing nice. The one is positioned to float right in the upper righthand corner of the parent div, and it won't let any other container float to the right of it. I tried display:inline and display:inline-block but no luck... Here's the code, though something tells me the answer is so easy you won't need it!: The parent div, the upper righthand corner div, and the poor div trying to float right: #um-home-section4 { width:100%; height:300px; background-color: green; } #um-title-right { float:right; width:500px; height:50px; margin-right:20px; margin-top:20px; background-color: fuchsia; } #take-me-there { float:right; margin-top:240px; margin-right:0px; height:50px; width:100px; background-color: gray; } <div id="um-home-section4"> <div id="um-title-right"></div> <div id="take-me-there"></div> </div>

Also I do not need all scalability stuff.

  • Show dialog while loading new screen

    - by darkdusky
    I have a front screen with a button which opens a second screen. The second screen can take a few seconds to load so I want to display a dialog while loading. My problem is the dialog does not display while loading second screen, but it displays when I return to first page from the second page. If I comment out the "startActivity" to open second page the dialog shows fine. I'm fairly new to android programming - I guess it has something to do with threads. //code snippet from inside onCreate: NewGame.setOnClickListener(new View.OnClickListener() { public void onClick(View arg0) { //does not get displayed before 2nd page opens showDialog(DIALOG2_KEY); //shows fine if next 2 lines commented out Intent i = new Intent(screen1.this, SudukuXL.class); startActivity(i); I've dealt with the dialog showing on returning to the front screen using onPause(). I've tried using threads to seperate the dialog from the startActivity but I've had no luck. Any help would be appreciated. I used code from Android examples to create dialog. I include below for reference: protected Dialog onCreateDialog(int id) { switch (id) { case DIALOG2_KEY: { ProgressDialog dialog = new ProgressDialog(this); dialog.setMessage("Loading..."); dialog.setIndeterminate(true); dialog.setCancelable(true); return dialog; } } return null; }

  • How grouping and totaling are done into three tables using JOIN

    Here are my tables respondents: field sample value respondentid : 1 age : 2 gender : male survey_questions: id : 1 question : Q1 answer : sample answer answers: respondentid : 1 question : Q1 answer : 1 --id of survey question I want to display all respondents who answered the certain survey, display all answers and total all the answer and group them according to the age bracket.

  • jquery select one class from many

    - by simnom
    Hi, I'm trying to achieve the following functionality. Within a form I have multiple fields with the class name .inputField if one of these fields is selected then the div associated with that element should be shown on focus and hidden on blur. However, when I implement the code below on selecting the second element the class is applied to both. Not sure where I'm going wrong?!?!? html markup: <form class="friendlyForm" name="friendlyForm" id="friendlyForm"> <ul> <li> <label for="testField">Test field</label> <input name="testField" value="here" class="inputField" id="testField" /> <div class="helper" style="display: none;">helper text here</div> </li> <li> <label for="testField">Test field2</label> <input name="testField2" value="here" class="inputField" id="testField2" /> <div class="helper" style="display: none;">helper text here</div> </li> </ul> </form> jQuery markup: $('.friendlyForm').find('.inputField').each(function(i) { $(this).blur(); $(this).focus(function() { //Add the focus class and fadeIn the helper div $(this).parent().addClass('focus'); $(this).parent().parent().find('.helper').fadeIn(); }); $(this).blur(function () { //Remove the focus class and fadeOut helper div $(this).parent().removeClass('focus'); $(this).parent().parent().find('.helper').fadeOut(); }); }); Any pointers here would be greatly appreciated.

  • Execute client & server side code with one click?

    i am not sure if my design have flaw but would like to know what others have to say, i am in a situation where i am trying to acheive two things in one click. using : asp.net web form i have a web form with few textbox and a gridview control and a button. if i click on the button i am executing two things 1) asynchronously get data from server to client (working great) and able to display the data in the textboxes. 2) same click i want to bind the gridview. <asp:Content ID="Content2" ContentPlaceHolderID="cphMaster" runat="server"> <asp:Label runat="server" ID='Label1' >Id:</asp:Label> <asp:TextBox ID="txtId" runat='server'></asp:TextBox> <asp:Button ID="btnSubmit" OnClientClick="LoadDataById();" runat="server" Text="Submit" onclick="btnSubmit_Click" /> <br /> <br /> <asp:TextBox ID="txtName" runat='server'></asp:TextBox> <br /> <asp:TextBox ID="txtPurpose" runat='server'></asp:TextBox> <br /> <br /> <asp:GridView ID="GridView1" runat="server"> </asp:GridView> </asp:Content> server side protected void btnSubmit_Click(object sender, EventArgs e) { GridView1.DataSource = laodData(int.Parse(txtId.Text)); GridView1.DataBind(); } Jquery: function LoadVisitBasicByVisitId() { ContactServiceProxy.invoke({ serviceMethod: "GetDataById", data: { request: request }, callback: function(response) { processCompletedContactStore(response); }, error: function(xhr, errorMsg, thrown) { postErrorAndUnBlockUI(xhr, errorMsg, thrown); } }); return false; } recap: 1) jquery script execute asynchronously to get data from server to client and display in the textboxes 2) server side code to bind the gridview.

  • Circular reference while setting up bidirectional communication line between two remote objects

    - by mphair
    I'm using .Net remoting to set up a bidirectional communication line between two objects. The basic structure is as follows: Instances of RemoteObjectA call methods on StaticObjectA. Instances of RemoteObjectB call methods on StaticObjectB. StaticObjectA needs to be able to call methods provided by RemoteObjectB. StaticObjectB needs to be able to call methods provided by RemoteObjectA. The problem with this setup is the circular reference in RemoteObjectA gets StaticObjectA gets RemoteObjectB gets StaticObjectB gets RemoteObjectA... I implemented an interface IRemoteObjectA and IRemoteObjectB and had the remote objects inheret from their respective interfaces, but then setting up the remoting fails. If the solution to this problem is: "don't use remoting", I can deal with that. Just wanted to make sure I wasn't missing a simple solution.

  • How to handle product ratings in a database

    - by Mel
    Hello, I would like to know what is the best approach to storing product ratings in a database. I have in mind the following two (simplified, and assuming a MySQL db) scenarios: Scenario 1: Create two columns in the product table to store number of votes and the sum of all votes. Use columns to get an average on the product display page: products(productedID, productName, voteCount, voteSum) Pros: I will only need to access one table, and thus execute one query to display product data and ratings. Cons: Write operations will be executed in a table whose original purpose is only to furnish product data. Scenario 2: Create an additional table to store ratings. products(productID, productName) ratings(productID, voteCount, voteSum) Pros: Isolate ratings into a separate table, leaving the products table to furnish data on available products. Cons: I will have to execute two separate queries on product page requests (one for data and another for ratings). In terms of performance, which of the following two approaches is best: Allow users to execute an occasional write query to a table that will handle hundreds of read requests? Execute two queries at every product page, but isolate the write query into a separate table. I'm a novice to database development, and often find myself struggling with simple questions such as these. Many thanks,

  • How to build custom sqlite with provider under Android?

    - by dr4cul4
    Hi, I have a really strange problem. I need to build custom sqlite3 database engine under Android OS, but I also want to use database provider implementation. Unfortunately when examining sources of Android 1.6 I noticed that it's not so easy. Many classes including android.database.; packages use original provider, also many other parts of framework use android.database.sqlite.; packages directly, wich ofcourse make this abstraction a bit confusing and unnesesary. But going to my question. If there is any way that I could extend database interfaces to use custom implmentation of sqlite (or any other database)?
