  • Python Textwrap - forcing 'hard' breaks

    - by Tom Werner
    I am trying to use textwrap to format an import file that is quite particular in how it is formatted. Basically, it is as follows (line length shortened for simplicity): abcdef <- Ok line abcdef ghijk <- Note leading space to indicate wrapped line lm Now, I have got code to work as follows: wrapper = TextWrapper(width=80, subsequent_indent=' ', break_long_words=True, break_on_hyphens=False) for l in lines: wrapline=wrapper.wrap(l) This works nearly perfectly, however, the text wrapping code doesn't do a hard break at the 80 character mark, it tries to be smart and break on a space (at approx 20 chars in). I have got round this by replacing all spaces in the string list with a unique character (#), wrapping them and then removing the character, but surely there must be a cleaner way? N.B Any possible answers need to work on Python 2.4 - sorry!

  • using NEWSEQUENTIALID() with UPDATE Trigger

    - by Ram
    I am adding a new GUID/Uniqueidentifier column to my table. ALTER TABLE table_name ADD VersionNumber UNIQUEIDENTIFIER UNIQUE NOT NULL DEFAULT NEWSEQUENTIALID() GO And when ever a record is updated in the table, I would want to update this column "VersionNumber". So I create a new trigger CREATE TRIGGER [DBO].[TR_TABLE_NAMWE] ON [DBO].[TABLE_NAME] AFTER UPDATE AS BEGIN UPDATE TABLE_NAME SET VERSIONNUMBER=NEWSEQUENTIALID() FROM TABLE_NAME D JOIN INSERTED I ON D.ID=I.ID/* some ID which is used to join*/ END GO But just realized that NEWSEQUENTIALID() can only be used with CREATE TABLE or ALTER TABLE. I got this error The newsequentialid() built-in function can only be used in a DEFAULT expression for a column of type 'uniqueidentifier' in a CREATE TABLE or ALTER TABLE statement. It cannot be combined with other operators to form a complex scalar expression. Is there a workaround for this ? Edit1: Changing NEWSEQUENTIALID() to NEWID() in the trigger solves this, but I am indexing this column and using NEWID() would be sub-optimal

  • Hibernate - why use many-to-one to represent a one-to-one?

    - by aberrant80
    I've seen people use many-to-one mappings to represent one-to-one relationships. I've also read this in a book by Gavin King and on articles. For example, if a customer can have exactly one shipping address, and a shipping address can belong to only one customer, the mapping is given as: <class name="Customer" table="CUSTOMERS"> ... <many-to-one name="shippingAddress" class="Address" column="SHIPPING_ADDRESS_ID" cascade="save-update" unique="true"/> ... </class> The book reasons as (quoting it): "You don't care what's on the target side of the association, so you can treat it like a to-one association without the many part." My question is, why use many-to-one and not one-to-one? What is it about a one-to-one that makes it a less desirable option to many-to-one? Thanks.

  • How to normalize a database where different user groups have different kinds of profiles?

    - by Stephen
    My application database has a Groups table that separates users into logical roles and defines access levels (admin, owner, salesperson, customer service, etc.) Groups has many Users. The Users table contains login details such as username and password. Now I wish to add user profiles to my database. The trouble I'm having (probably due to my relative unfamiliarity with proper database normalization) is that different user groups have different kinds of profiles. Ergo, a salesperson's profile will include his commission percentage, whereas an admin or customer service would not need this value. So, would the proper method be to create a unique profile table for each group? (e.g. admin_profiles, or salesperson_profiles). or is there a better way that combines certain details in a generic profile, while some users have extended info. And if so, whats a good example of how to do this with the commission example given?

  • Put specific tds from a table row into edit using jQuery (then update w/ ajax)

    - by bbqsauced
    I'm somewhat new to jQuery, so I could use some help here. This is my issue: I have a php script outputting a dynamic table. Each row has an "edit" button, plus some other fields. Only 3 of those need to be turned into an input box. The edit button should only put that specific row into "edit mode." I got as far as assigning each row a unique class by adding a number to the end of it. I have been able to use jQuery to change all of the rows into edit mode, but I need it to be specific to a row. An example row would have classes like name0, price0, and desc0. The next row would go on to classes name1, price1, and desc1 (for the fields that need changed). How can I reference these values and pass them to jQuery so it processes an event on just those elements?

  • .Net Round-trip Types

    - by Fujiy
    I making a method that generate a unique string key for some parameters. But the same key if call with same values. I just accept primitive types, string, DateTime, Guid, and Nullable(since I append types together, I can distinguish who is int and who is int?), because I can convert all to string without lost values or precision.(for float and double a use ToString("R"), to DateTime ToString("O")). Exists a easy way to know which types I can transform in strings without conflict? And how do this transform(how I said before, float, double and datetime have specific ways) Thanks

  • HttpSessionState Where, How, Advantages?

    - by blgnklc
    You see the code below, how I did use the session variable; So the three questions are; 1- Where are they stored? (Server or Client side) 2- Are they unique for each web page visitor? 3- Can I remove it using ajax or simple js code when my job is done with it? or it will be removed automatically..? sbyte[][] arrImages = svc.getImagesForFields(new String[] { "CustomerName", "CustomerSurName" }); Dictionary<string, byte[]> smartImageData = new Dictionary<string, byte[]>(); int i = 0; foreach (sbyte[] bytes in arrImages) { smartImageData.Add(fieldNames[i], ConvertToByte(bytes)); i++; } Session.Add("SmartImageData", smartImageData);

  • MS Excel 03 - Deleting rows that have live string identifiers in column A, while concatenating other

    - by Justin
    I have this xml document that is provided as a data feed (right off the bat I can not modify the source of the data feed) and i import it into excel with the xml import. there is no schema that comes with this xml so i get a table that ends up having a whole bunch of duplicates for an identifier, because of the unique values spread throughout the spreadsheet. XML in XLS Col1(IDnum) Col2(name) Col3(Type) Col4(Category) Col(etc) ================================================================= 0011 Item 01 6B 0011 Item xxj9 7B 0011 Item xxj9 0011 Item 02 0011 Item 01 xxj9 6B 0012 etc I need to delete all rows where columnA string/number matches while concatenating all potential values from Col3, Col4 & Col5 together so it looks like this Col1(IDnum) Col2(name) Col3(Type) Col4(Category) Col(etc) ================================================================= 0011 Item 01, 02 xxj9 6B, 7B what visual basic method would allow me to accomplish this? thanks

  • How do i build a custom "Your Account" dynamic page with wordpress?

    - by Colour Blend
    Hello everyone. Please can you help with a guideline on this requirement? I have this requirement that some visitors to my site would need to login and be provided access to an Accounts page. This page will contain a list of links added by the site administrator which just lead to pages with specific contents. Every page/link is unique to a user(Account). No two user will ever have to see one page. Please help me. I just need a guide, you don't need to spoon feed me. Thanks in advance.

  • Secure to store an ID in an ASP.NET control ID?

    - by Curtis White
    I'm auto-generating a form in my ASP.NET page. This is already tested and working. I want to know if: If there are any security problems with storing the database ID as part of my controls ID? I can see think of 2 issues: the id will be visible in page source (not really important in this case), and the possibility someone could change the name of the control somehow? This second possibility is more serious. Is this a potential problem and how to void it? If there would be a better preferred way to associate a unique data with any type of control? Is it possible to store a custom item in the viewstate for the control?

  • Indexing affects only the WHERE clause?

    - by andre matos
    If I have something like: CREATE INDEX idx_myTable_field_x ON myTable USING btree (field_x); SELECT COUNT(field_x), field_x FROM myTable GROUP BY field_x ORDER BY field_x; Imagine myTable with around 500,000 rows and most of field_x values being unique. Since I don't use any WHERE clause, will the created index have any effect at all in my query? Edit: I'm asking this question because I don't get any relevant difference between query-times before and after creating the index; They always take about 8 seconds (which, of course is too much time!). Is this behaviour expected?

  • Sort Java List/Map by order in which items are in an XML File

    - by Brandon Smith
    Hello everyone, What I'm looking to do is to sorta a Java List or Map in the order the items are in a XML File. For Example I have a list of function names as so: functionOne functionThree functionTwo The XML File looks like this: <xml> <function>functionOne</function> <function>functionTwo</function> <function>functionThree</function> </xml> So I would like to sort the list so the function names are as so: functionOne functionTwo functionThree Now Im trying to do this for Variables as well, so there are around 500+ unique 'items'. Does anyone have any idea how I can go about doing this? Now for the file that determines that sort order doesn't have to be XML it just what I use the most, it can be anything that can get the job done. Thanks in advance for your time.

  • batch - append either date/time of creation or random to end of filename

    - by Maclovin
    Hi Damsel in distress needing help with a batch-script. I have a bunch of files that one system creates. Either in one of 2 directories, or in the directory above that. The naming is apparently not very important, so It's a bit random. 2 questions for you batch-geniuses out there. a) How can I append date/time of creation to the end of the filename with a batch-script? b) How can I append a random filename (so I make the files unique) with a batch-script? Thanks in advance, dudes and dudettes. Yours sincerely, the Maclovin!

  • Seeking FOSS user admin code

    - by Mawg
    It must be a fairly standard wheel, so I'd rather not reinvent it. Create/modify/delete users. Ditto their passwords & maybe enforce password change every X days. Also, create groups, like "sales", "support", etc and add/remove users. The only unique part should be what they have permission to do (visit certain parts of the site after login, etc) And I'd like to store admin data in an ODBC compliant database (MySql to start with, but I may move on). Is this a new wheel? There doesn't seem to be much of anything on SourceForge, but if I could find something established and trusted I wouldn't even mind paying a few $100 as a trade of for the time needed to develop & test it.

  • Using a JSON web service from a Java client application

    - by user383341
    I am developing a client-side Java application that has a bit of functionality that requires getting data from some web services that transmit in JSON (some RESTful, some not). No JavaScript, no web browser, just a plain JAR file that will run locally with Swing for the GUI. This is not a new or unique problem; surely there must be some open source libraries out there that will handle the JSON data transmission over HTTP. I've already found some that will parse JSON, but I'm having trouble finding any that will handle the HTTP communication to consume the JSON web service. So far I've found Apache Axis2 apparently which might have at least part of the solution, but I don't see enough documentation for it to know if it will do what I need, or how to use it. Maybe part of the problem is that I don't have experience with web services so I'm not able to know a solution when I see it. I hope some of you can point me in the right direction. Examples would be helpful.

  • Can a primary key be equal to a different column?

    - by eric
    I know that a primary key must be unique, but is it okay for a primary key to be equal to a different column in the same table by coincidence? For instance, I have 2 tables. One table is called person that holds information about a person (ID, email, telephone, address, name). The other table is staff (ID, pID(person ID), salary, position). In staff the ID column is the primary key and is used to uniquely identify a staff member. The number is from 1 - 100. However, the pID (person ID) may be equal to the ID. For instance the staff ID may be 1 and the pID that it references to may be equal to 1. Is that okay?

  • Where does the data model go in a Prism app?

    - by HawkeyeJoeS
    I'm having trouble where to put our data model in our Prism app. Most, if not all or our data will be coming from web services and the web services are unique for each module. Unfortunately, there will be objects that need to be shared (such as a person/user object). I'm really torn about whether to add these services directly to the module, so that each is truly independent, or create a separate project to house the web service proxies and business entities. The modules are being built by different teams, but will all live in the same solution (and source control, of course).

  • SQL: Is it quicker to insert sorted data into a table?

    - by AngryWhenHungry
    A table in Sybase has a unique varchar(32) column, and a few other columns. It is indexed on this column too. At regular intervals, I need to truncate it, and repopulate it with fresh data from other tables. insert into MyTable select list_of_columns from OtherTable where some_simple_conditions order by MyUniqueId If we are dealing with a few thousand rows, would it help speed up the insert if we have the order by clause for the select? If so, would this gain in time compensate for the extra time needed to order the select query? I could try this out, but currently my data set is small and the results don't say much.

  • Stored Connection Strings per user

    - by pehaada
    In the past I've used a Singleton Pattern to load the connection string when the application starts via the global.asa file. I have a project now where each user has a unique connection string to the database. I would like to load this connection string once. The issue is that the singleton pattern will not work for me since each user has there own connection string. Basically the connection string is created dynamically. I do not want to store it is session. If anyway has a clever way of doing this in .NET let me know ?

  • How can I make this code more generic

    - by Greg
    Hi How could I make this code more generic in the sense that the Dictionary key could be a different type, depending on what the user of the library wanted to implement? For example someone might what to use the extension methods/interfaces in a case where there "unique key" so to speak for Node is actually an "int" not a "string" for example. public interface ITopology { Dictionary<string, INode> Nodes { get; set; } } public static class TopologyExtns { public static void AddNode(this ITopology topIf, INode node) { topIf.Nodes.Add(node.Name, node); } public static INode FindNode(this ITopology topIf, string searchStr) { return topIf.Nodes[searchStr]; } } public class TopologyImp : ITopology { public Dictionary<string, INode> Nodes { get; set; } public TopologyImp() { Nodes = new Dictionary<string, INode>(); } }

  • Random select is not always returning a single row.

    - by Lieven
    The intention of following (simplified) code fragment is to return one random row. Unfortunatly, when we run this fragment in the query analyzer, it returns between zero and three results. As our input table consists of exactly 5 rows with unique ID's and as we perform a select on this table where ID equals a random number, we are stumped that there would ever be more than one row returned. Note: among other things, we already tried casting the checksum result to an integer with no avail. DECLARE @Table TABLE ( ID INTEGER IDENTITY (1, 1) , FK1 INTEGER ) INSERT INTO @Table SELECT 1 UNION ALL SELECT 2 UNION ALL SELECT 3 UNION ALL SELECT 4 UNION ALL SELECT 5 SELECT * FROM @Table WHERE ID = ABS(CHECKSUM(NEWID())) % 5 + 1

  • how to create a auto-incremented attribute in xcode managed object model

    - by Mausimo
    Hey, what i want to do is to make a int that will be the ID of the entity and auto increment itself whenever a new entity is added (just like a SQL identity property). Is this possible? i tried using indexed (checked on attribute) however there is no description to what indexed even does. EDIT: I am adding annotations to a map, when you click the pin the annotationview with a chevron shows up. Now when you click this button i would like to load an associated picture. However the only way i know how to link the picture to this button is to give the picture a unique id, and then set the button.tag to this id and then load based on the button.tag.
