  • C++ Long switch statement or look up with a map?

    - by Rachel
    In my C++ application, I have some values that act as codes to represent other values. To translate the codes, I've been debating between using a switch statement or an stl map. The switch would look something like this: int code; int value; switch(code) { case 1: value = 10; break; case 2: value = 15; break; } The map would be an stl::map<int, int> and translation would be a simple lookup with the code used as the key value. Which one is better/more efficient/cleaner/accepted? Why?

  • Sharing [config] data across modules,functions

    - by williamstw
    I have some configuration data in a config file that I read off disk when the app starts. I need to make that configuration data available to other functions/modules in the application. I started down the path of looking into ets/mnesia to store the data on startup to make it shared among all processes, but then my inner voice cautioned me that there must be a more functional, erlang-y way to do this. The only alternate approach I've come up with so far is setting up a module that has an actor loop that reads the data on startup and responds to messages like {Key, From} and responds by From ! {ok,Value}. Then, I gave up and decided to ask... Thanks, --tim

  • Is there a way to automate MS Office applications without license?

    - by james-h-l
    I am currently writing an application that will perform automation in Excel. I have MS Office (2007) installed on my work computer and the application is working fine referencing the the Microsoft Excel 12.0 Object Lirary. The target machine has the Office installed but not registered. It is one of those preinstalled editions. Attempting to run the application on the target machine I get an error saying Office is not installed? I'm assuming then you have to have a registed Office to use the object libraries? Is there anyway around this as I do not have a Office license key lying around and its quite expensive?

  • MySQL get row closest to NOW()

    - by Christopher McCann
    I have a table with User data such as name, address etc and another table which has a paragraph of text about the user. The reason that they are separate is because we need to record all the old about data. So if the user changes their paragraph - the old one should still be stored. Each bit of about data has a primary key aboutMeID. What I want to do is have a join that pulls their name, address etc and the latest bit of aboutMe data from the other table. I am not sure though how I can order the join to only get the latest about me data. Can someone help?

  • Blackberry Code

    - by Haoest
    I have having difficulties protecting my blackberry application persistent data with ControlledAccess object. According to http://www.blackberry.com/developers/docs/4.5.0api/net/rim/device/api/system/PersistentObject.html, I need a PersistentObject, CodeSignKey, and ControlledAccess objects to work. I have everything except one piece: CodeSignKey codeSigningKey = CodeSigningKey.get( "ACME" ); here, I don't know what to replace for "ACME". Is this the PIN code I chose as I filled out the Code Sign Key? Is it my package name, output file name? The Blackberry API documentation doesn't seem to say anything about this particularly important parameter. Help please, thanks.

  • Hibernate: how to maintain insertion order

    - by jwaddell
    I have a list of entities where creation order is important, but they do not contain a timestamp to use for sorting. Entities are added to the end of the list as they are created so they will be ordered correctly in the list itself. After persisting the list using Hibernate the entities appear in the database table in the order that they were created. However when retrieving the list using a new Hibernate session the list is now in reverse order of insertion/creation. Is this expected behaviour? Is there any way to retrieve the list in the same order as it appears in the table? The primary key is a UUID, and the list of entities should always have been created on the same IP address and JVM. This mean sorting by UUID is a possibility but I'd rather not make assumptions. Another possibility is if the list is guaranteed to always come out in reverse order I could always just work through it backwards.

  • T-SQL to PL/SQL (IDENTITY)

    - by folone
    I've got a T-SQL script, that converts field to IDENTITY (in a weird way). How do I convert it to PL/SQL? (and, probably, figure out, if there is a simpler way to do this - without creating a temporary table). The T-SQL script: -- alter table ts_changes add TS_THREADID VARCHAR(100) NULL; -- Change Field TS_ID TS_NOTIFICATIONEVENTS to IDENTITY BEGIN TRANSACTION GO CREATE TABLE dbo.Tmp_TS_NOTIFICATIONEVENTS ( TS_ID int NOT NULL IDENTITY (1, 1), TS_TABLEID int NOT NULL, TS_CASEID int NULL, TS_WORKFLOWID int NULL, TS_NOTIFICATIONID int NULL, TS_PRIORITY int NULL, TS_STARTDATE int NULL, TS_TIME int NULL, TS_WAITSTATUS int NULL, TS_RECIPIENTID int NULL, TS_LASTCHANGEDATE int NULL, TS_ELAPSEDCYCLES int NULL ) ON [PRIMARY] SET IDENTITY_INSERT dbo.Tmp_TS_NOTIFICATIONEVENTS ON GO IF EXISTS(SELECT * FROM dbo.TS_NOTIFICATIONEVENTS) EXEC('INSERT INTO dbo.Tmp_TS_NOTIFICATIONEVENTS (TS_ID, TS_TABLEID, TS_CASEID, TS_WORKFLOWID, TS_NOTIFICATIONID, TS_PRIORITY, TS_STARTDATE, TS_TIME, TS_WAITSTATUS, TS_RECIPIENTID, TS_LASTCHANGEDATE, TS_ELAPSEDCYCLES) SELECT TS_ID, TS_TABLEID, TS_CASEID, TS_WORKFLOWID, TS_NOTIFICATIONID, TS_PRIORITY, TS_STARTDATE, TS_TIME, TS_WAITSTATUS, TS_RECIPIENTID, TS_LASTCHANGEDATE, TS_ELAPSEDCYCLES FROM dbo.TS_NOTIFICATIONEVENTS WITH (HOLDLOCK TABLOCKX)') GO SET IDENTITY_INSERT dbo.Tmp_TS_NOTIFICATIONEVENTS OFF GO DROP TABLE dbo.TS_NOTIFICATIONEVENTS GO EXECUTE sp_rename N'dbo.Tmp_TS_NOTIFICATIONEVENTS', N'TS_NOTIFICATIONEVENTS', 'OBJECT' GO ALTER TABLE dbo.TS_NOTIFICATIONEVENTS ADD CONSTRAINT aaaaaTS_NOTIFICATIONEVENTS_PK PRIMARY KEY NONCLUSTERED ( TS_ID ) WITH( STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] GO COMMIT

  • How do i style a JSON feed in my view?

    - by stephenmurdoch
    My rails app gets the following JSON feed from mixcloud and sticks the results into my index page At the moment when I do this, the entire contents of my feed are displayed unformatted in one big blob of scary looking text (without the curly JSON brackets) I only want to display specific values from the feed in the view. From the feed in question lets say for simplicity that I just wanted to display all values with a key of "url" In case I'm doing something wrong here's my code: # podcast controller def index # I'm using a class method to get the feed @feed = Podcast.feed end # podcast model def self.feed feed = JSON.parse(open("http://api.mixcloud.com/alivefrommaryhill/feed").read) end # index.html.haml .feed = @feed I can't figure out how to style the results and display only certain items from the feed. Is my approach wrong?

  • Software protection

    - by anfono
    I want to protect my software from being used without permission. I will provide it for free to the parties I authorize to use it. Anyone knows a good protection scheme against having it copied and run by unauthorized parties ? So far, I thought about introducing a key validation mechanism: periodically, the user needs to send me (web site query) a code based on which I generate a new code that app validates against. There is an initial code, and so I can track users... Thoughts ? Later edit: I changed the licensing part to avoid unfocused discussion.

  • Ria Services loading foreign keys with Linq-to-SQL

    - by Stephan
    I have a database that consists of 5 tables : Course, Category, Location, CourseCategories, and CourseLocations. The last 2 tables just contain the two foreign keys. A Course has many-to-many relationships with both category and location. I am trying to load the data into a Silverlight app using Ria Services. My DB model is Linq-to-SQL. I have tried adding the [Include] attribute to the metadata classes and I have added the DataLoadOptions so it should load the all tables when you ask for a Course. However on the client side I am never getting back any entries in the CourseCategories and CourseLocations properties. What else needs to be done to get the foreign key relationships to exist across the serialization.

  • STL map containing references does not compile

    - by MTsoul
    The following: std::map<int, ClassA &> test; gives: error C2101: '&' on constant While the following std::map<ClassA &, int> test; gives error C2528: '_First' : pointer to reference is illegal The latter seems like map cannot contain a reference for the key value, since it needs to instantiate the class sometimes and a reference cannot be instantiated without an object. But why does the first case not work?

  • Trying to catch integrity error with sqlaclhemey

    - by Lostsoul
    I'm having problems with trying to catch a error. I'm using pyramid/sqlalchemy and made a sign up form with email as the primary key. The problem is when a duplicate email is entered it raises a IntegrityError, so I'm trying to catch that error and provide a message but no matter what I do I can't catch it(the error keeps appearing). try: new_user = Users(email, firstname, lastname, password) DBSession.add(new_user) return HTTPFound(location = request.route_url('new')) except IntegrityError: message1 = "Yikes! Your email already exists in our system. Did you forget your password?" I get the same message when I tried except exc.SQLAlchemyError (although I want to catch specific errors and not a blanket catch all). Is there something wrong with my python syntax? or is there something I need to do special in sqlalchemy to catch it?

  • HQL multiple updates. Is there a better way?

    - by folone
    I have a Map, that I want to persist. The domain object is something like this: public class Settings { private String key; private String value; public String getKey() { ... } public String getValue() { ... } public void setKey() { ... } public void setValue() { ... } } The standard approach is to generate a Setting for each pair, and saveOrUpdate() it. But it generates way too much queries, because I need to save lots of settings at a time, and it really affects perfomance. Is there a way to do this using one update query?

  • How can I check if a value exists in a list using C#

    - by Samantha J
    I have the following code that gives me a list of id and names from the new ASP.NET MVC5 Identity: var identityStore = new IdentityStore(); var users = ( from user in identityStore.DbContext.Set<User>() select new { id = user.Id, name = user.UserName } ); How could I modify this so that it allows me to check if a UserName exists? Here's the user class: public class User : IUser { public User(); public User(string userName); [Key] public string Id { get; set; } public virtual ICollection<UserLogin> Logins { get; set; } public virtual UserManagement Management { get; set; } public virtual ICollection<UserRole> Roles { get; set; } public string UserName { get; set; } }

  • SQL: without a cursor, how to select records making a unique integer id (identity like) for dups?

    - by Dr. Zim
    If you have the select statement below where the PK is the primary key: select distinct dbo.DateAsInt( dateEntered) * 100 as PK, recordDescription as Data from MyTable and the output is something like this (the first numbers are spaced for clarity): PK Data 2010 01 01 00 New Years Day 2010 01 01 00 Make Resolutions 2010 01 01 00 Return Gifts 2010 02 14 00 Valentines day 2010 02 14 00 Buy flowers and you want to output something like this: PK Data 2010 01 01 01 New Years Day 2010 01 01 02 Make Resolutions 2010 01 01 03 Return Gifts 2010 02 14 01 Valentines day 2010 02 14 02 Buy flowers Is it possible to make the "00" in the PK have an "identity" number effect within a single select? Otherwise, how could you increment the number by 1 for each found activity for that date? I am already thinking as I type to try something like Sum(case when ?? then 1 end) with a group by.

  • How do I digitally sign an HTTPS request in .net?

    - by Endy Tjahjono
    Is there a built in procedure to digitally sign an HTTPS request with client's SSL private key in .net? Also, is there a built in procedure to verify the digital signature against an SSL certificate? Or do I have to roll my own? Or is there a third party library? I need the request to be digitally signed because the client manipulates money, so I want to be sure that the request really comes from the client and that nobody tampers with the content of the request. I'm also considering using SSL client certificate, but it can only provide confidentiality and authentication, but not data integrity.

  • Replacing substring in a string

    - by user177785
    I am uploading a image file to the server. Now after uploading the file to the server I need to rename the file with an id, but the extension of the file should be retained. Eg: if I upload the file image1.png then my server script should retain the extension .png. But I need to change the substring to some other substring (primary key of db). image1.png should be renamed to 123.png image2.jpg should be renamed to somevalue.jpg The image can be of any extension like .png, .jpg, .jpeg etc. I want to rename then in such a way that the image/file extension should be retained.
