• How do I indent multiple lines at once in Notepad++?

  - by cdeszaq

  In many text editors that are aimed at programmers, if the user has a selection that spans more than 1 line and presses the TAB key, those lines are indented by 1 TAB (or a number of spaces, depending on how the editor is configured). However, this does not seem to be the default behavior of Notepad++. Is there a way I can do this in Notepad++, or is there a plugin that I can get to allow me to do this? Edit: Upon additional testing, shift-tab correctly un-indents the lines as expected, but only a tab simply inserts a tab wherever the carat is. This is in version 5.4.5 Unicode

• Database Compression in Python

  - by user551832

  I have hourly logs like user1:joined user2:log out user1:added pic user1:added comment user3:joined I want to compress all the flat files down to one file. There are around 30 million users in the logs and I just want the latest user log for all the logs. My end result is I want to have a log look like user1:added comment user2:log out user3:joined Now my first attempt on a small scale was to just do a dict like log['user1'] = "added comment" Will doing a dict of 30 million key/val pairs have a giant memory footprint.. Or should I use something like sqllite to store them.. then just put the contents of the sqllite table back into a file?

• Will creating index help in this case

  - by The King

  I'm still a learning user of SQL-SERVER2005. Here is my table structure CREATE TABLE [dbo].[Trn_PostingGroups]( [ControlGroup] [char](5) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL, [PracticeCode] [char](5) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL, [ScanDate] [smalldatetime] NULL, [DepositDate] [smalldatetime] NULL, [NameOfFile] [varchar](50) COLLATE SQL_Latin1_General_CP1_CI_AS NULL, [DepositValue] [decimal](11, 2) NULL, [RecordStatus] [char](1) COLLATE SQL_Latin1_General_CP1_CI_AS NULL, CONSTRAINT [PK_Trn_PostingGroups_1] PRIMARY KEY CLUSTERED ( [ControlGroup] ASC, [PracticeCode] ASC )WITH (IGNORE_DUP_KEY = OFF) ON [PRIMARY] ) ON [PRIMARY] Scenario 1 : Suppose I have a query like this... Select * from Trn_PostingGroups where PracticeCode = 'ABC' Will indexing on Practice Code seperately help me in making my query faster?? Scenario 2 : Select * from Trn_PostingGroups where ControlGroup = 12701 and PracticeCode = 'ABC' and NameOfFile = 'FileName1' Will indexing on NameOfFile seperately help me in making my query faster ??

• How do I set properties related to the calling method's scope?

  - by Thiado de Arruda

  I'm not looking for a way to associate values with a thread using the 'SetData' method. I need to store some kind of data that will only exist during the scope of a calling method, could be the immediate parent or any other call that is made down on the stack. For example: void SomeMethod() { string someInfo = "someInfo"; SomeOtherMethod(); object data = GetDataOnCurrentScope("someKey"); } void SomeOtherMethod() { SetDataOnParentScope("someKey", somevalue); } In this case both the 'someInfo' local variable and the data set with the "someKey" key will disapear after 'SomeMethod' returns. Is something like this possible? This may go against the rules of a stack, but who knows if someone has an idea...

• SQL-Join with NULL-columns

  - by tstenner

  I'm having the following tables: Table a +-------+------------------+------+-----+ | Field | Type | Null | Key | +-------+------------------+------+-----+ | bid | int(10) unsigned | YES | | | cid | int(10) unsigned | YES | | +-------+------------------+------+-----+ Table b +-------+------------------+------+ | Field | Type | Null | +-------+------------------+------+ | bid | int(10) unsigned | NO | | cid | int(10) unsigned | NO | | data | int(10) unsigned | NO | +-------+------------------+------+ When I want to select all rows from b where there's a corresponding bid/cid-pair in a, I simply use a natural join SELECT b.* FROM b NATURAL JOIN a; and everything is fine. When a.bid or a.cid is NULL, I want to get every row where the other column matches, e.g. if a.bid is NULL, I want every row where a.cid=b.cid, if both are NULL I want every column from b. My naive solution was this: SELECT DISTINCT b.* FROM b JOIN a ON ( ISNULL(a.bid) OR a.bid=b.bid ) AND (ISNULL(a.cid) OR a.cid=b.cid ) Is there any better way to to this?

• SVN: How can I update an existing repository from an exported copy ?

  - by user206705

  Late one afternoon, I did an export of my project repository, and took home my work on my USB key. I've added many changes to the exported project, and now, having returned to the workplace, I want to update the repository with the project that I've now got. To complicate matters, I've made updates to the project in both the main trunk and a branch - and I'd like to update the repository to reflect all those changes. I'm new to SVN and have been relying on tortoise SVN, but I'm a bit lost now. Would I be best to delete the repository and recreate it from the copies/branches I now have? thanks

• SQLite: does data type depend on the quotes?

  - by Septagram

  In SQLite, the datatype of a value is associated with the value itself, not with the column type. So suppose we have a table with an integer primary key "id" and an integer column "some_number". If I do a query like this: INSERT INTO mytable (id, some_number) VALUES (NULL, "1234") Will 123 be inserted as an integer or as string? What consequences it will have later for me, say, when I'm comparing it with other value like "234" (as a number 1234 234, as a string "1234" < "234", right?)?

• Doctrine: Mixing YAML markup and db manager (navicat) editing?

  - by ropstah

  I think the answer to this question should be: No. However I hope to be corrected. I'd like to edit our database using a mixture of YAML markup + Doctrine createTables() and Navicat editing. Can I maintain the inheritance which is marked up? Example (4 steps, at step 4, Doctrine is in no way able to re-create the inheritance schema... or is it?): Step 1: Create YAML with inheritance --- Entity: columns: username: string(20) password: string(16) created_at: timestamp updated_at: timestamp User: inheritance: extends: Entity type: column_aggregation keyField: type keyValue: 1 Group: inheritance: extends: Entity type: column_aggregation keyField: type keyValue: 2 Step 2: Create tables using Doctrine (and drop/create db if nessecary) Created sql: CREATE TABLE entity (id BIGINT AUTO_INCREMENT, username VARCHAR(20), password VARCHAR(16), created_at DATETIME, updated_at DATETIME, type VARCHAR(255), PRIMARY KEY(id)) ENGINE = INNODB Step 3: Edit table using Navicat Step 4: Refresh YAML file because of 'external' edits...

• super-space-optimized code

  - by Will

  There are key self-contained algorithms - particularly cryptography-related such as AES, RSA, SHA1 etc - which you can find many implementations of for free on the internet. Some are written to be nice and portable clean C. Some are written to be fast - often with macros, and explicit unrolling. As far as I can tell, none are trying to be especially super-small - so I'm resigned to writing my own - explicitly AES128 decryption and SHA1 for ARM THUMB2. What patterns and tricks can I use to do so? Are there compilers/tools that can roll-up code?

• Security issues in accepting passwords vs auto generating the password

  - by Vivekanand Poojari

  Hi, I am developing a console application. This application generates a self signed certificate and installs it in the current machine's certificate store. The steps invlolved are :- Generate a certificate Create a pfx file Install the pfx file For these steps i would need a password for protecting the private key and the pfx file. However these passwords are used only during the execution of the exe. Should I auto generate a password using some random number generation algorithm or accept the password as input from the user? What are the security issues involved in both the scenarios ? Thanks Vivekanand

• No difference between nullable:true and nullable:false in Grails 1.3.6?

  - by knorv

  The following domain model definition .. class Test { String a String b static mapping = { version(false) table("test_table") a(nullable: false) b(nullable: true) } } .. yields the following MySQL schema .. CREATE TABLE test_table ( id bigint(20) NOT NULL AUTO_INCREMENT, a varchar(255) NOT NULL, b varchar(255) NOT NULL, PRIMARY KEY (id) ) ENGINE=InnoDB DEFAULT CHARSET=utf8; Please note that a and b get identical MySQL column definitions despite the fact a is defined as non-nullable and b is nullable in the GORM mappings. What am I doing wrong? I'm running Grails 1.3.6.

• Rails: id field is nil when calling Model.new

  - by Joe Cannatti

  I am a little confused about the auto-increment id field in rails. I have a rails project with a simple schema. When i check the development.sqlite3 I can see that all of my tables have an id field with auto increment. CREATE TABLE "messages" ("id" INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL, "text" text, "created_at" datetime, "updated_at" datetime); but when i call Message.new on the console, the resulting object has an id of nil >> a = Message.new => #<Message id: nil, text: nil, created_at: nil, updated_at: nil> shouldn't the id come back populated?

• Redirect on catching an exception in a method in the model

  - by Arkid

  I am using Authlogic-connect to connect various service providers. There is a method in user.rb def complete_oauth_transaction token = token_class.new(oauth_token_and_secret) old_token = token_class.find_by_key_or_token(token.key, token.token) token = old_token if old_token if has_token?(oauth_provider) self.errors.add(:tokens, "you have already created an account using your #{token_class.service_name} account, so it") else self.access_tokens << token end end When a service provider is already added it gives the error as stated in the has_token? method and the page breaks. I need to redirect the app to the same page and flash the error. How do i do this? I have overridden the method in my own user.rb so that I can change the code.

• Persistent SQL Table lock from C#

  - by Chris

  I'm trying to create a persistent SQL (SQL Server 2005) lock on a table level. I'm not updating/querying the specified table, but I need to prevent a third party application from updating the locked table as a means to prevent transactions from being posted (the table I wish to lock is the key on their transaction that interferes with my processing). From my experience the table is only locked for the time a specific transaction is taking place. Any ideas? The 3rd party developer has logged this feature as an enhancement, but since they are in the middle of rolling out a major release I can expect to wait at least 6 months for this. I know that this isn't a great solution, since their software will fall over but it is of a critical enough nature that we're willing to live with the consequences.

• How to call javascript function when url variable is sent

  - by mattlarkin

  Hello, heres basically what I need to get done. I have a jsp page which allows me to add/modify/delete an item. The items are stored in a database which I have controller classes to access(dont worry bout that part) When an item gets selected and deleted the id of the item gets sent to the controller to be processed. The item will not always be deleted if their is a foreign key constraint so I send either a delete=true or delete=false through url back to the jsp page. I would like to have it so a javascript function gets called displaying an alert saying the item was deleted or the item was not deleted. can someone please tell me the best way to do this? thank you

• Improving the performance of an nHibernate Data Access Layer.

  - by Amitabh

  I am working on improving the performance of DataAccess Layer of an existing Asp.Net Web Application. The scenerios are. Its a web based application in Asp.Net. DataAccess layer is built using NHibernate 1.2 and exposed as WCF Service. The Entity class is marked with DataContract. Lazy loading is not used and because of the eager-fetching of the relations there is huge no of database objects are loaded in the memory. No of hits to the database is also high. For example I profiled the application using NHProfiler and there were about 50+ sql calls to load one of the Entity object using the primary key. I also can not change code much as its an existing live application with no NUnit test cases at all. Please can I get some suggestions here?

• WP7 - attempt to select and use application static resource in codebehind not working (no resources found).

  - by pearcewg

  With Windows Phone 7, I'm attempting to dynamically add controls to and object in codebehind, and apply a StaticResource to the new control. Xaml file sample: <phone:PhoneApplicationPage.Resources> <ControlTemplate x:Key="PushpinControlTemplateBlue" TargetType="my2:Pushpin"> ... </ControlTemplate> </phone:PhoneApplicationPage.Resources> Codebehind sample: >Pushpin myPush = new Pushpin(); >myPush.Location = new GeoCoordinate(52.569593, -0.9261151403188705); >myPush.Content = ""; >myPush.Template = (ControlTemplate)Application.Current.Resources["PushpinControlTemplateBlue"]; >mapMain.Children.Add(myPush); When I debug, and look at "Application.Current.Resources", there are no items in the collection, so the item is added to the controls list, but doesn't show up because it has no content. Is there something simple I'm doing wrong? How do I correctly access the resource?

• Merge array in a different way in PHP

  I have these two arrays: $array1 = array( '0' => 'apple', '1' => '' , '2' => 'cucumber' ); $array2 = array( '0' => '', '1' => 'bmw', '2' => 'chrysler' ); if I do this to merge these arrays: $result_arr = array_merge($array1, $array2); print_r( count ( array_filter($result_arr) ) ); the output would be 4. However, I need to get the number 3. So, when there are two things on the same position (same key) count it only once. Is it possible to merge/count elements in arrays like that?
