  • IoC.Resolve vs Constructor Injection

    - by Omu
    I heard a lot of people saying that it is a bad practice to use IoC.Resolve(), but I never heard a good reason why (if it's all about testing than you can just mock the container, and you're done). now the advantages of using Resolve instead of Constructor Injection is that you don't need to create classes that have 5 parameters in the constructor, and whenever you are going to create a instance of that class you're not gonna need to provide it with anything

  • Writing a function for UIAlertView?

    - by worchyld
    I'm sick of writing basic UIAlertView's, ie: UIAlertView *alert = [[UIAlertView alloc] initWith...]] //etc Instead of doing this, is it possible to put all this in a "helper" function, where I can return the buttonIndex, or whatever an alert usually returns? For a simple helper function I guess you could feed parameters for the title, message, I'm not sure whether you can pass delegates in a parameter though, or bundle info. In pseudo-code, it could be like this: someValueOrObject = Print_Alert(Title="", Message="", Delegate="", Bundle="") // etc Any help on this would be great. Thanks

  • Best way to model Customer <--> Address

    - by Jen
    Every Customer has a physical address and an optional mailing address. What is your preferred way to model this? Option 1. Customer has foreign key to Address Customer (id, phys_address_id, mail_address_id) Address (id, street, city, etc.) Option 2. Customer has one-to-many relationship to Address, which contains a field to describe the address type Customer (id) Address (id, customer_id, address_type, street, city, etc.) Option 3. Address information is de-normalized and stored in Customer Customer (id, phys_street, phys_city, etc. mail_street, mail_city, etc.) One of my overriding goals is to simplify the object-relational mappings, so I'm leaning towards the first approach. What are your thoughts?

  • Visual Studio Generating Code in Release mode

    - by bball
    I am using Visual Studio to compile some C++ Code. When I compile my program in Debug mode it works perfectly, but when I try compiling it in Release mode, VS halts when Generating Code (ie: took 20 mins and still didn't finish). After I forced VS to stop the build process, the executable generated was huge 2MB while it should be about 304KB. Please can you help figure this out. How should I setup the configuration parameters for Release mode to work? Thanks,

  • Importing a spreadsheet, but having trouble.

    - by Chris Phelps
    I have a form that allows a user to import a spreadsheet. This spreadsheet is generally static when it comes to column headers, but now the users want to be able to include an optional column (called Notes). My code crashes when I try to read the column from the spreadsheet if it doesn't exist. Dim objCommand As New OleDbCommand() objCommand = ExcelConnection() 'function that opens spreadsheet and returns objCommand Dim reader As OleDbDataReader reader = objCommand.ExecuteReader() While reader.Read() Dim Employee As String = Convert.ToString(reader("User")) Dim SerialNUM As String = Convert.ToString(reader("serialno")) **Dim Notes As String = Convert.ToString(reader("notes"))** If the spreadsheet contains a Notes column, all goes well. If not, crash. How can I check to see if the Notes column exists in the spreadsheet to avoid the crash?

  • I can't get areas working in VS2010

    - by devlife
    I just upgraded from VS2010 RC to RTM. Now my areas aren't working. I have a Profile area with a Home controller and an Action method Index(). If I try: http://localhost:4951/profile I get a 404 error saying that the resource can't be found. If I try http://localhost:4951/profile/home I get the same error. However, if I try http://localhost:4951/profile/home/index then the view is returned. Here is my ProfileAreaRegistration: public class ProfileAreaRegistration : AreaRegistration { public override string AreaName { get { return "Profile"; } } public override void RegisterArea(AreaRegistrationContext context) { context.MapRoute( "Profile_Unlock", "Profile/Unlock/{userID}/{unlockID}", new { controller = "Unlock", action = "Index" }, new { userID = new GuidRouteConstraint(), unlockID = new GuidRouteConstraint() } ); context.MapRoute( "Profile_default", "Profile/{controller}/{action}/{id}", new { action = "Home", id = UrlParameter.Optional } ); } Does anyone know what is going wrong?

  • 64-bit integers in Cython

    - by Homayoon
    I'm trying to interface a C++ library (pHash) with Python using Cython, but I have trouble with some of the types. The library functions use "unsigned long long" and I can't find a way to declare variables and parameters with this type. I searched for a list of the types that I can use with cdef but I found nothing. Can anyone point me to such a list (if it exists) or otherwise suggest a way to use 64 bit types in Cython? Thanks.

  • Is there any way to use GUIDs in django?

    - by Jason Baker
    I have a couple of tables that are joined by GUIDs in SQL Server. Now, I've found a few custom fields to add support for GUIDs in django, but I tend to shy away from using code in blog posts if at all possible. I'm not going to do anything with the GUID other than join on it and maybe assign a GUID on new entries (although this is optional). Is there any way to allow this using django's built-in types? Like can I use some kind of char field or binary field and "trick" django into joining using it? If it's any help, I'm using django-pyodbc.

  • Filling a LOV in Oracle Apex based on data in another text box

    - by Martin Pugh
    I am fairly new to Oracle Apex, and have a problem. Our application currently has a method of entering data, with several text boxes and Optional List of Values. I would like to have an LOV based on information in another text box like so: select APPOINTMENT_ID PATIENT_ID from APPOINTMENT where PATIENT_ID = :P9_PAT_NUM where P9_PAT_NUM is a patient number in a text box. However, this would apparently only work if the text box has already been submitted, else it assumes the text box is null. Is there any way to get this working with an LOV, or perhaps some other method?

  • Creating a db driven primary navigation in django?

    - by Fedor
    I find that it's pretty common most people hardcode the navigation into their templates, but I'm dealing with a pretty dynamic news site which might be better off if the primary nav was db driven. So I was thinking of having a Navigation model where each row would be a link. link_id INT primary key link_name varchar(255) url varchar(255) order INT active boolean If anyone's done something similar in the past, would you say this sort of schema is good enough? I also wanted for there to be an optional dropdown in the admin near the url field so that a user could choose a Category model's slug since category links would be common, but I'm not quite sure how that would be possible.

  • javascript error: variable is not defined

    - by Hristo
    to is not defined [Break on this error] setTimeout('updateChat(from, to)', 1); I'm getting this error... I'm using Firebug to test and this comes up in the Console. The error corresponds to line 71 of chat.js and the whole function that wraps this line is: function updateChat(from, to) { $.ajax({ type: "POST", url: "process.php", data: { 'function': 'getFromDB', 'from': from, 'to': to }, dataType: "json", cache: false, success: function(data) { if (data.text != null) { for (var i = 0; i < data.text.length; i++) { $('#chat-box').append($("<p>"+ data.text[i] +"</p>")); } document.getElementById('chat-box').scrollTop = document.getElementById('chat-box').scrollHeight; } instanse = false; state = data.state; setTimeout('updateChat(from, to)', 1); // gives error }, }); } This links to process.php with function call getFromDB and the code for that is: case ('getFromDB'): // get the sender and receiver user IDs from their user names $from = mysql_real_escape_string($_POST['from']); $query = "SELECT `user_id` FROM `Users` WHERE `user_name` = '$from' LIMIT 1"; $result = mysql_query($query) or die(mysql_error()); $row = mysql_fetch_assoc($result); $fromID = $row['user_id']; $to = mysql_real_escape_string($_POST['to']); $query = "SELECT `user_id` FROM `Users` WHERE `user_name` = '$to' LIMIT 1"; $result = mysql_query($query) or die(mysql_error()); $row = mysql_fetch_assoc($result); $toID = $row['user_id']; $query = "SELECT * FROM `Messages` WHERE `from_id` = '$fromID' AND `to_id` = '$toID' LIMIT 1"; $result = mysql_query($query); while($row = mysql_fetch_assoc($result)) { $text[] = $line = $row['message']; $log['text'] = $text; } break; So I'm confused with the line that is giving the error. setTimeout('updateChat(from,to)',1); aren't the parameters to updateChat the same parameters that came into the function? Or are they being pulled in from somewhere else and I have to define to and from else where? Any ideas how to fix this error? Thanks, Hristo

  • Auto injecting logger with guice

    - by koss
    With reference to Guice's custom injections article, its TypeListener performs a check for InjectLogger.class annotation - which can be optional. Removing that check will inject to all Logger.class types. class Log4JTypeListener implements TypeListener { public <T> void hear(TypeLiteral<T> typeLiteral, TypeEncounter<T> typeEncounter) { for (Field field : typeLiteral.getRawType().getDeclaredFields()) { if (field.getType() == Logger.class && field.isAnnotationPresent(InjectLogger.class)) { typeEncounter.register(new Log4JMembersInjector<T>(field)); } } } } I'm tempted to remove "&& field.isAnnotationPresent(InjectLogger.class)" from the listener. If we're using Guice to inject all instances of our Logger, is there any reason not to do it automatically (without need to annotate)?

  • How can I determine a file extension given a file name in LaTeX?

    - by Frank
    I am attempting to write a LaTeX package which leverages the minted package's \inputminted command. My \mycommand command takes two parameters, the first being a path to a file, and I want to pass the file's extension to the \inputminted command: \newcommand\mycommand[2]{ \inputminted{#1}{...} } Note that the above won't work since the full path is passed to \inputminted. Example: \mycommand{/path/to/Test.java}{blah} should invoke \inputminted{java}{...}

  • Does any language have a while-else flow structure?

    - by dotancohen
    Consider this flow structure which I happen to use often: if ( hasPosts() ) { while ( hasPosts() ) { displayNextPost(); } } else { displayNoPostsContent(); } Are there any programming languages which have an optional else clause for while, which is to be run if the while loop is never entered? Thus, the code above would become: while ( hasPosts() ) { displayNextPost(); } else { displayNoPostsContent(); } I find it interesting that many languages have the do-while construct (run the while code once before checking the condition) yet I have never seen while-else addressed. There is precedent for running an N block of code based on what was run in N-1 block, such as the try-catch construct. I wasn't sure whether to post here or on programmers.SE. If this question is more appropriate there, then please move it. Thanks.

  • What are the rules about using an underscore in a C++ identifier?

    - by Roger Lipscombe
    It's common in C++ to name member variables with some kind of prefix to denote the fact that they're member variables, rather than local variables or parameters. If you've come from an MFC background, you'll probably use "m_foo". I've also seen "myFoo" occasionally. C# (or possibly just .NET) seems to recommend using just an underscore, as in "_foo". Is this allowed by the C++ standard?
