  • Static analysis of multiple if statements (conditions)

    - by koppernickus
    I have code similar to: if conditionA(x, y, z) then doA() else if conditionB(x, y, z) then doB() ... else if conditionZ(x, y, z) then doZ() else throw ShouldNeverHappenException I would like to validate two things (using static analysis): If all conditions conditionA, conditionB, ..., conditionZ are mutually exclusive (i.e. it is not possible that two or more conditions are true in the same time). All possible cases are covered, i.e. "else throw" statement will never be called. Could you recommend me a tool and/or a way I could (easily) do this? I would appreciate more detailed informations than "use Prolog" or "use Mathematica"... ;-)

  • Find and Replace RegEx question

    - by fraXis
    I am starting to get a grip on RegEx thanks to all the great help here on SO with my other questions. But I am still suck on this one: My code is: StreamReader reader = new StreamReader(fDialog.FileName.ToString()); string content = reader.ReadToEnd(); reader.Close(); I am reading in a text file and I want to search for this text and change it (the X and Y value always follow each other in my text file): X17.8Y-1. But this text can also be X16.1Y2.3 (the values will always be different after X and Y) I want to change it to this X17.8Y-1.G54 or X(value)Y(value)G54 My RegEx statement follows but it is not working. content = Regex.Replace(content, @"(X(?:\d*\.)?\d+)*(Y(?:\d*\.)?\d+)", "$1$2G54"); Can someone please modify it for me so it works and will search for X(wildcard) Y(Wildcard) and replace it with X(value)Y(value)G54?

  • How do I embed an expect script that takes in arguments into a bash shell script?

    - by fzkl
    I am writing a bash script which amongst many other things uses expect to automatically run a binary and install it by answering installer prompts. I was able to get my expect script to work fine when the expect script is called in my bash script with the command "expect $expectscriptname $Parameter". However, I want to embed the expect script into the shell script instead of having to maintain two separate script files for the job. I searched around and found that the procedure to embed expect into bash script was to declare a variable like VAR below and then echo it.: VAR=$(expect -c " #content of expect script here ") echo "$VAR" 1) I don't understand how echoing $VAR actually runs the expect script. Could anyone explain? 2) I am not sure how to pass $Parameter into VAR or to the echo statement. This is my main concern. Any ideas? Thanks.

  • !(ReferenceEquals()) vs != in Entity Framework 4

    - by Eric J.
    Unless a class specifically overrides the behavior defined for Object, ReferenceEquals and == do the same thing... compare references. In property setters, I have commonly used the pattern private MyType myProperty; public MyType MyProperty { set { if (myProperty != value) { myProperty = value; // Do stuff like NotifyPropertyChanged } } } However, in code generated by Entity Framework, the if statement is replaced by if (!ReferenceEquals(myProperty, value)) Using ReferenceEquals is more explicit (as I guess not all C# programmers know that == does the same thing if not overridden). Is there any difference that's escaping me between the two if-variants? Are they perhaps accounting for the possibility that POCO designers may have overridden ==? In short, if I have not overridden ==, am I save using != instead of ReferencEquals()?

  • Casting To The Correct Subclass

    - by kap
    Hi Guys I hava a supeclass called Car with 3 subclasses. class Ford extends Car{ } class Chevrolet extends Car{ } class Audi extends Car{ } Now i have a function called printMessge(Car car) which will print a message of a particular car type. In the implementation i use if statements to test the instance of the classes like this. public int printMessge(Car car){ if((Ford)car instanceof Ford){ // print ford }else if((Chevrolet)car instanceof Chevrolet){ // print chevrolet }else if((Audi)car instanceof Audi){ // print Audi } } for instance if i call it for the first time with Ford printMessge(new Ford()), it prints the ford message but when i call it with printMessge(new Chevrolet()), i get EXCEPTION from the first if statement that Chevrolet cannot be cast to Ford. What am i doing wrong and what is the best way. thanks

  • Instantiating a context in LINQ to Entities

    - by Jagd
    I've seen two different manners that programmers approach when creating an entity context in their code. The first is like such, and you can find it all over the MSDN code examples: public void DoSomething() { using TaxableEducationEntities context = new TaxableEducationEntities()) { // business logic and whatever else } } The second is to create the context as a private attribute in some class that encapsulates your business logic. So you would have something like: public class Education_LINQ { private TaxableEducationEntities context = new TaxableEducationEntities(); public void DoSomething() { var result = from a in context.luAction select a; // business logic and whatever else } } Which way is more efficient? Assume that you have two methods, one called DoSomething1() and another called DoSomething2(), and both methods incorporate the using statement to open the context and do whatever with it. Were you to call one method after the other, would there be any superfluous overhead going on, since essentially both methods create the context and then clean it up when they're done? As opposed to having just one private attribute that is created when a class object is instantiated, and then in turn cleaned up when the object goes out of scope?

  • Entity Framework mant to many insert

    - by Jacob
    I've been playing around with Entity Framework v2 and added some code to insert new entity with many to many relationship , lets say this entity is called meeting. I add hours to meeting : meeting.Hours.Add(hour); and I get different errors on different occasions On Update : Cannot insert the value NULL into column 'Meetings_Id', table 'Plan.dbo.MeetingHour'; column does not allow nulls. INSERT fails. The statement has been terminated. On Inset : An item with the same key has already been added. But the tricky party is that if I add this manually trough SQL Server Management Studio , I can update the entity with the same value , clearing it first (meeting.Hour.Clear()) Can't see what could be the problem , maybe entity model isn't mapped correctly ?

  • How dynamic can I make my LINQ To SQL Statements?

    - by mcass20
    I have the need to construct a LINQ To SQL statement at runtime based on input from a user and I can't seem to figure out how to dynamically build the WHERE clause. I have no problem with the following: string Filters = "<value>FOO</value>"; Where("FormattedMessage.Contains(@0)",Filters) But what I really need is to make the entire WHERE clause dynamic. This way I can add multiple conditions at runtime like this (rough idea): foreach (Filter filter in filterlist) { whereclause = whereclause + "&& formattedmessage.contains(filter)"; }

My problem is that I use this plugin in two areas on my site: one on a black background, and one on a white background. I need to use an alternate set of play/pause buttons for each page (white buttons for the black background and vice versa). I am at a total loss on how to do this. I need to some how incorporate a "if page is..." statement into the wpaudio.js but I don't know how to do this with jQuery. Can anyone help? Thanks so much!

  • SQL SELECT: "Give me all documents where all of the documents procedures are 'work in progress'"

    - by prestonmarshall
    This one really has me stumped. I have a documents table which hold info about the documents, and a procedures table, which is kind of like a revisions table for each document. What I need to do is write a select statement which gives me all of the documents where all of the procedures have the status "work_in_progress". Here's an example procedures table: document_id | status 1 | 'wip' 1 | 'wip' 1 | 'wip' 1 | 'approved' 2 | 'wip' 2 | 'wip' 2 | 'wip' Here, I would want my query to only return document id 2, because all of its statuses are work_in_progress. I DO NOT want document_id 1 since one of its statuses is 'approved'. I believe this is relational division I want, but I'm not sure where to start. This is MySQL 5.0 FYI.

  • Database Version Control SQL Server 2008 Drop SP's and Functions

    - by Lieven Cardoen
    I'm working on versioning our database and now searching for a way to drop all stored procedures and functions from a C# Console Application. I'd rather not create a stored procedure that drops all stored procedures and functions. I has to be some sql executed from C#. I tried to drop the stored procedure before creating it, but I get this message: System.Data.SqlClient.SqlException: 'CREATE/ALTER PROCEDURE' must be the first statement in a query batch. Script for one SP for example: DROP PROCEDURE [dbo].[sp_Economatic_LoadJournalEntryFeedbackByData] SET ANSI_NULLS ON SET QUOTED_IDENTIFIER ON CREATE PROCEDURE [dbo].[sp_Economatic_LoadJournalEntryFeedbackByData] @Data VARCHAR(MAX) AS BEGIN ... END So I guess before creating all SP's and functions I'll need to drop all SP's and functions first with one sql script.

  • How to write a linter?

    - by jbdavid
    In my day job I, and others on my team write a lot of hardware models in Verilog-AMS, a language supported primarily by commercial vendors and a few opensource simulator projects. One thing that would make supporting each others code more helpful would be a LINTER that would check our code for common problems and assist with enforcing a shared code formatting style. I of course want to be able to add my own rules and, after I prove their utility to myself, promote them to the rest of the team.. I don't mind doing the work that has to be done, but of course also want to leverage the work of other existing projects. Does having the allowed language syntax in a yacc or bison format give me a leg up? or should I just suck each language statement into a perl string, and use pattern matching to find the things I don't like? (most syntax and compilation errors are easily caught by the commercial tools.. but we have some of our own extentions.)

I have tried using the eval() function but that doesn't seem to work. Here is what I'm trying right now and it doesn't seem to work: my $temp = $qryResults[0]; print $temp."\n"; eval{"$temp"}; the output is $con->Disconnect();exit; Thanks for the help!

  • Linq to SQL Error with Many-to-Many table

    - by Matt Connolly
    I am getting the following error with linq-to-sql when I try to access a many-to-many collection: Members 'Int32 XXX' and 'Int32 YYY' both marked as IsPrimaryKey and IsDbGenerated. The statement is true, in that both of those columns are primary key integers with identity insert. The table I am trying to access has a foreign key to both YYY and ZZZ, and then ZZZ has a foreign key to XXX. There doesn't appear to be anything wrong with my data structure. I tried setting "Child Property" to false on the ZZZ-YYY relationship, but it didn't change anything.

  • Unique Key in MySql

    - by Vinodtiru
    I have a table with four Columns. Col1, Col2, Col3, and Col4. Col1, Col2, Col3 is string and Col4 is a integer primary key with Auto Increment. Now my requirement is to have unique combination of Col2 and Col3. I mean to say like. Insert into table(Col1,Col2,Col3) Values('val1','val2','val3'); Insert into table(Col1,Col2,Col3) Values('val4','val2','val3'); the second statement has to throw error as the same combination of 'val2','val3' is present in the table. But i cant make it as a primary key as i need a auto increment column and for that matter the col4 has to be primary. Please let me know a approach by which i can have both in my table. Any kind of help is appreciated. Thanks.

  • Find and replace string in MySQL using data from another table

    - by Charlie
    Hi, sorry for formatting this wonky but hope you can understand it. I have two MySql tables, and I want to find and replace text strings in one using data in another. Texts - one column: messages 'thx guys' 'i think u r great' 'thx again' ' u rock' Dictionary - two columns: bad_spelling, good_spelling 'thx' 'thanks' ' u ' ' you ' ' r ' ' are ' I want SQL to go through and look at every row in messages and replace every instance of bad_spelling with good_spelling, and to do this for all the pairs of bad_spelling and good_spelling The closest I have gotten is this: update texts, dictionary set texts.message = replace(texts.message, dictionary.bad_spelling, dictionary.good_spelling) But this only changes 'thx' to 'thanks' (in 2 rows) and does not go on to replace ' u ' with ' you' or ' r ' with ' are '. Any ideas how to make it use all the rows in dictionary in the replace statement? -- PS forgot to mention that this is a small example and in the real thing I will have a lot of find/replace pairs, which may get added to over time.

  • How to dynamically choose two fields from a Linq query as a result

    - by Dr. Zim
    If you have a simple Linq query like: var result = from record in db.Customer select new { Text = record.Name, Value = record.ID.ToString() }; which is returning an object that can be mapped to a Drop Down List, is it possible to dynamically specify which fields map to Text and Value? Of course, you could do a big case (switch) statement, then code each Linq query separately but this isn't very elegant. What would be nice would be something like: (pseudo code) var myTextField = db.Customer["Name"]; // Could be an enumeration?? var myValueField = db.Customer["ID"]; // Idea: choose the field outside the query var result = from record in db.Customer select new { Text = myTextField, Value = myValueField };

  • use doctest and logging in python program

    - by Luke
    #!/usr/bin/python2.4 import logging import sys import doctest def foo(x): """ foo (0) 0 """ print ("%d" %(x)) _logger.debug("%d" %(x)) def _test(): doctest.testmod() _logger = logging.getLogger() _logger.setLevel(logging.DEBUG) _formatter = logging.Formatter('%(message)s') _handler = logging.StreamHandler(sys.stdout) _handler.setFormatter(_formatter) _logger.addHandler(_handler) _test() I would like to use logger module for all of my print statements. I have looked at the first 50 top google links for this, and they seem to agree that doctest uses it's own copy of the stdout. If print is used it works if logger is used it logs to the root console. Can someone please demonstrate a working example with a code snippet that will allow me to combine. Note running nose to test doctest will just append the log output at the end of the test, (assuming you set the switches) it does not treat them as a print statement.

  • Can MySQL Nested Select return list of results

    - by John
    Hi I want to write a mysql statement which will return a list of results from one table along with a comma separated list of field from another table. I think an example might better explain it Table 1 ======================== id First_Name Surname ---------------------- 1 Joe Bloggs 2 Mike Smith 3 Jane Doe Table 2 ======================== id Person_Id Job_id --------------------- 1 1 1 2 1 2 3 2 2 4 3 3 5 3 4 I want to return a list of people with a comma separated list of job_ids. So my result set would be id First_Name Surname job_id ------------------------------ 1 Joe Bloggs 1,2 2 Mike Smith 2 3 Jane Doe 3,4 I guess the sql would be something like select id, First_Name, Surname, (SELECT job_id FROM Table 2) as job_id from Table 1 but obviously this does not work so need to change the '(SELECT job_id FROM Table 2) as job_id' part. Hope this makes sense Thanks John

  • Batch View updates

    - by Terry
    I want to load a bunch of view definitions into SQL Server 2005 & 2008. I am using IF/ELSE logic to dynamically building Create or Alter statements that I then EXEC. This works fine. However, unless I get the order of the statements correct, I get errors if a view is dependent on another view that would be created in a later statement. Is there a way to turn of the valiation of the SQL statements until after they have all been entered? It seems like the worst of both worlds. SQL Server does late binding and so it won't propogate changes to tables and views, but you can't create a view without all the pieces being in place.

  • How do I pass argument from an activity to another in Workflow 4

    - by Jimmy Engtröm
    Hi I have created an Activity (CodeActivity) that retrieves the temperature where I live. I wan't to add that activity to a workflow and connect it to an if statement/activity that can based on my temperature outargument do different things. But I can't seem to find how to access the outargument from my temperature-activity. This is my first Windows Workflow 4 project so perhaps I'm attacking this in the wrong way. I have: public OutArgument Degrees { get; set; } But how do I access it? I have found tutorials how to get the data when running the activity (only one) but not as part of a workflow. Hope my question makes sence. /Jimmy

  • How do you convert date taken from a bash script to milliseconds in a Java program?

    - by Matt Pascoe
    I am writing a piece of code in Java that needs to take a time sent from a bash script and parse the time to milliseconds. When I check the millisecond conversion on the date everything is correct except for the month I have sent which is January instead of March. Here is the variable I create in the bash script, which later in the script I pass to the Java program: TIME=`date +%m%d%Y_%H:%M:%S` Here is the Java code which parses the time to milliseconds: String dt = "${scriptstart}"; java.text.SimpleDateFormat scriptStart = new java.text.SimpleDateFormat("MMDDyyyy_HH:mm:ss"); long start = scriptStart.parse(dt).getTime(); The goal of this statement is to find the elapsed time between the start of the script and the current system time. To troubleshoot this I printed out the two: System Time = 1269898069496 (converted = Mon Mar 29 2010 16:27:49 GMT-0500 (Central Daylight Time)) Script Start = 03292010_16:27:45 Script Start in Milli = 1264804065000 (Converted = Fri Jan 29 2010 16:27:45 GMT-0600 (Central Standard Time))

  • Is there a Perl module or technique that makes using long namespaces easier?
