• 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

• Create signed urls for CloudFront with Ruby

  - by wiseleyb

  History: I created a key and pem file on Amazon. I created a private bucket I created a public distribution and used origin id to connect to the private bucket: works I created a private distribution and connected it the same as #3 - now I get access denied: expected I'm having a really hard time generating a url that will work. I've been trying to follow the directions described here: http://docs.amazonwebservices.com/AmazonCloudFront/latest/DeveloperGuide/index.html?PrivateContent.html This is what I've got so far... doesn't work though - still getting access denied: def url_safe(s) s.gsub('+','-').gsub('=','_').gsub('/','~').gsub(/\n/,'').gsub(' ','') end def policy_for_resource(resource, expires = Time.now + 1.hour) %({"Statement":[{"Resource":"#{resource}","Condition":{"DateLessThan":{"AWS:EpochTime":#{expires.to_i}}}}]}) end def signature_for_resource(resource, key_id, private_key_file_name, expires = Time.now + 1.hour) policy = url_safe(policy_for_resource(resource, expires)) key = OpenSSL::PKey::RSA.new(File.readlines(private_key_file_name).join("")) url_safe(Base64.encode64(key.sign(OpenSSL::Digest::SHA1.new, (policy)))) end def expiring_url_for_private_resource(resource, key_id, private_key_file_name, expires = Time.now + 1.hour) sig = signature_for_resource(resource, key_id, private_key_file_name, expires) "#{resource}?Expires=#{expires.to_i}&Signature=#{sig}&Key-Pair-Id=#{key_id}" end resource = "http://d27ss180g8tp83.cloudfront.net/iwantu.jpeg" key_id = "APKAIS6OBYQ253QOURZA" pk_file = "doc/pk-APKAIS6OBYQ253QOURZA.pem" puts expiring_url_for_private_resource(resource, key_id, pk_file) Can anyone tell me what I'm doing wrong here?

• 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 to create Shared VB Array Initialisors for NerdDinner

  - by David A Gibson

  Hello, I am trying to work my way through the NerdDinner tutorial - and as an exercise I'm converting it to VB as I go. I'm not very far in and after having gotten past the C# Yield statement I'm stuck on Shared VB Array Initialisors. static IDictionary<string, Regex> countryRegex = new Dictionary<string, Regex>() { { "USA", new Regex("^[2-9]\\d{2}-\\d{3}-\\d{4}$")}, { "UK", new Regex("(^1300\\d{6}$)|(^1800|1900|1902\\d{6}$)|(^0[2|3|7|8]{1}[0- 9]{8}$)|(^13\\d{4}$)|(^04\\d{2,3}\\d{6}$)")}, { "Netherlands", new Regex("(^\\+[0-9]{2}|^\\+[0- 9]{2}\\(0\\)|^\\(\\+[0-9]{2}\\)\\(0\\)|^00[0-9]{2}|^0)([0-9]{9}$|[0-9\\- \\s]{10}$)")}, Can anyone please help me write this in VB? Public Shared countryRegex As IDictionary(Of String, Regex) = New Dictionary(Of String, Regex)() {("USA", New Regex("^[2-9]\\d{2}-\\d{3}-\\d{4}$"))} This code has an error as it does not accept the String and the Regex as an item for the array. Thanks

• Most efficient way to check if a date falls between two dates?

  - by Dave Jarvis

  Given: Start Month & Start Day End Month & End Day Any Year What SQL statement results in TRUE if a date lands between the Start and End days? 1st example: Start Date = 11-22 End Date = 01-17 Year = 2009 Specific Date = 2010-01-14 TRUE 2nd example: Start Date = 11-22 End Date = 11-16 Year = 2009 Specific Date = 2010-11-20 FALSE 3rd example: Start Date = 02-25 End Date = 03-19 Year = 2004 Specific Date = 2004-02-29 TRUE I was thinking of using the MySQL functions datediff and sign plus a CASE condition to determine whether the year wraps, but it seems rather expensive. Am looking for a simple, efficient calculation. Update The problem is the end date cannot simply use the year. The year must be increased if the end month/day combination happens before the start date. The start date is easy: Start Date = date( concat_ws( '-', year, Start Month, Start Day ) The end date is not so simple. Thank you!

• 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))

• best way to parse plain text file with a nested information structure

• Raspberry Pi cluster, neuron networks and brain simulation

  - by jokoon

  Since the RBPI (Raspberry Pi) has very low power consumption and very low production price, it means one could build a very big cluster with those. I'm not sure, but a cluster of 100000 RBPI would take little power and little room. Now I think it might not be as powerful as existing supercomputers in terms of FLOPS or others sorts of computing measurements, but could it allow better neuronal network simulation ? I'm not sure if saying "1 CPU = 1 neuron" is a reasonable statement, but it seems valid enough. So does it mean such a cluster would more efficient for neuronal network simulation, since it's far more parallel than other classical clusters ?

• Run sql script from Ruby

  - by Chaker Nakhli

  Hi all, Using DBI::DatabaseHandle#execute or DBI::DatabaseHandle#prepare it's not possible to run an sql script (with mutiple sql statments). It fails with the following error : ERROR: cannot insert multiple commands into a prepared statement I tried to use the "unprepared" way using DBI::DatabaseHandle#do (the doc says it "goes straight to the DBD‘s implementation") but it keeps throwing the same error. code snippet: require 'dbd/pg' require 'dbi' DBI.connect("dbi:pg:database=dbname", db_user, db_password, db_params) do |dbh| schema = IO::read(schema_file) dbh.do(schema) end I'm using ruby 1.8.6 (2007-09-24 patchlevel 111) [i386-mswin32] dbi-0.4.3 dbd-pg-0.3.9 pg-0.9.0-x86-mswin32 Thank you!

• Slow SQLite access on iPhone

  - by georgij

  I have a quite slow data retrieval from a sqlite database on my iPhone and perhaps someone have an alternative idea to explain this. From what I tracked down so far sqlite3_step(statement) is sometimes unusually slow. While retrieving e.g. 50 rows from the database to execute this step takes normally some milliseconds but sometimes it takes several seconds. My database is not small (80MB) and my theory is that the reason is paging. But can someone else think of an other reason for this?

• Seemingly useless debugging environment for Android

  - by mikeY

  I've just started debugging my first three line long android app and I can't seem to use the debug tool like I want to. Here's my code: public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); int a = 1 / 0; } Now I expect the debugger to halt the thread and show me the line number of statement where the division by zero occurs. No, instead it shows some other method internal to the system for which I have no source. To make the matters worse, there is no exception message either. Prior to this app, I created one which would do something when a button was pressed. If any exception was raised, again no useful line number or exception message would be shown. As of right now, there is no way to debug my app. Any ideas? I'm using the latest SDK along with Eclipse ADT plugin and debugging on a real device (Nexus One).

• How to leverage concurrency checking with EF 4.0 POCO Self Tracking Entities in a N-Tier scenario?

  - by Mark Lindell

  I'm using VS1010RC with the POCO self tracking T4 templates. In my WCF update service method I am using something similar to the following: using (var context = new MyContext()) { context.MyObjects.ApplyChanges(myObject); context.SaveChanges(); } This works fine until I set ConcurrencyMode=Fixed on the entity and then I get an exception. It appears as if the context does not know about the previous values as the SQL statement is using the changed entities value in the WHERE clause. What is the correct approach when using ConcurrencyMode=Fixed?

• .NET : Targeting the runtime

  - by contactmatt

  I'm starting to read in-depth on the .NET framework, and its Common Language Runtime. I'm reading a .NET overview by Microsoft and I'm not sure what is meant by this statement. Code that targets the runtime is known as managed code, while code that does not target the runtime is known as unmanaged code. How do you target the Common Language Runtime? I know its defaulted when developing in Visual Studio, but how would you specifically target the CLR? What code when developing a .NET application wouldn't target the CLR, and thereby be called unmanaged code?

• WCF method called twice

  - by Saurabh Lalwani

  Hi, I have a web service which is returning data to the desktop application. The problem I am having is, when the web service returns small volume of data everything works fine but when the volume of data is large it throws the following exception: System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a receive. And when I am debugging the web service, I see that this particular method is called twice. It executes the return statement 1st time nothing happens, but when it does execute it for the second time the above mentioned exception is thrown in the desktop app. I found similar posts before on stackoverflow but they did not solve my problem. Can anybody please tell me what's going on in here? Thanks!

• try/catch: errors or exceptions?

  - by Josh

  OK. I may be splitting hairs here, but my code isn't consistent and I'd like to make it so. But before I do, I want to make sure I'm going the right way. In practice this doesn't matter, but this has been bothering me for a while so I figured I'd ask my peers... Every time I use a try... catch statement, in the catch block I always log a message to my internal console. However my log messages are not consistent. They either look like: catch(err) { DFTools.console.log("someMethod caught an error: ",err.message); ... or: catch(ex) { DFTools.console.log("someMethod caught an exception: ",ex.message); ... Obviously the code functions properly either way but it's starting to bother me that I sometimes refer to "errors" and sometimes to "exceptions". Like I said, maybe I'm splitting hairs but which is the proper terminology? "Exception", or "Error"?

• 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.

• Database Instance

  - by Sam

  I read a statement from an exercise: construct a database instance which conforms to diagram 1 but not to diagram 2. The diagrams are different n-ary relationships that have different relationships. Diagram 1 has a many to one to many to one relationship. Diagram 2 has many to many to many to one relationship. So, to really understand this problem, what does a database instance mean? Is it to make an example or abstract entities like a1, a2, or a3. Thanks for your time.

• Using Spring's KeyHolder with programmatically-generated primary keys

  Hello, I am using Spring's NamedParameterJdbcTemplate to perform an insert into a table. The table uses a NEXTVAL on a sequence to obtain the primary key. I then want this generated ID to be passed back to me. I am using Spring's KeyHolder implementation like this: KeyHolder key = new GeneratedKeyHolder(); jdbcTemplate.update(Constants.INSERT_ORDER_STATEMENT, params, key); However, when I run this statement, I am getting: org.springframework.dao.DataRetrievalFailureException: The generated key is not of a supported numeric type. Unable to cast [oracle.sql.ROWID] to [java.lang.Number] at org.springframework.jdbc.support.GeneratedKeyHolder.getKey(GeneratedKeyHolder.java:73) Any ideas what I am missing?

• How can I generate an Expression tree that queries an object with List<T> as a property?
