  • Need to search email body for regex using VBA

    - by user6620
    I am trying to write a script that I can run from a rule withing outlook. The goal of this script is to search the email body for a regex pattern, \d{8}-\d{3}\(E\d\) in this case. I want to take that pattern and see if a folder with the name of the match exists and if not create one. I am not super familiar with VBA as I write mostly in python. I have copied and pasted the following bit of code together but at this time I am unable to get the MsgBox to appear when I send an email with 20120812-001(E3) in the body. I have two different versions below. --version 2-- Sub Filter(Item As Outlook.MailItem) Dim Matches, Match Dim RegEx As New RegExp RegEx.IgnoreCase = True RegEx.Pattern = "\d{8}-\d{3}(E\d)" If RegEx.Test(Item.Body) Then MsgBox "Pattern Detected" End If End Sub --Version 1-- Sub ProcessMessage(myMail As Outlook.MailItem) Dim strID As String Dim objNS As Outlook.NameSpace Dim objMsg As Outlook.MailItem Dim objMatch As Match Dim RetStr As String Set objRegExp = New RegExp objRegExp.Pattern = "\d{8}-\d{3}\(E\d\)" objRegExp.IgnoreCase = True objRegExp.Global = True strID = myMail.EntryID Set objNS = Application.GetNamespace("MAPI") Set objMsg = objNS.GetItemFromID(strID) MsgBox objMsg.Body Set objMatch = objRegExp.Execute(objMsg.Body) MsgBox objMatch End Sub

  • Writing a JMS Publisher without "public static void main"

    - by The Elite Gentleman
    Hi guys, Every example I've seen on the web, e.g. http://www.codeproject.com/KB/docview/jms_to_jms_bridge_activem.aspx, creates a publisher and subscriber with a public static void main method. I don't think that'll work for my web application. I'm learning JMS and I've setup Apache ActiveMQ to run on JBoss 5 and Tomcat 6 (with no glitches). I'm writing a messaging JMS service that needs to send email asynchronously. I've already written a JMS subscriber that receives the message (the class inherits MessageListener). My question is simple: How do I write a publisher that will so that my web applications can call it? Does it have to be published somewhere? My thought is to create a publisher with a no-attribute constructor (in there) and get the MessageQueue Factory, etc. from the JNDI pool (in the constructor). Is my idea correct? How do I subscribe my subscriber to the Queue Receiver? (So far, the subscriber has no constructor, and if I write a constructor, do I always subscribe myself to the Queue receiver?) Thanks for your help, sorry if my terminology is not up to scratch, there are too many java terminologies that I get lost sometimes (maybe a java GPS will do! :-) ) PS Is there a tutorial out there that explains how to write a "better" (better can mean anything, but in my case it's all about performance in high demand requests) JMS Publisher and Subscriber that I can run on Application Server such as JBoss or Glassfish? Don't forget that the JMS application will needs a "guarantee" uptime as many applications will use this.

  • Git checkout doesn't change anything, and it's getting very frustrating

    - by Josh
    I really like git. At least, I like the idea of git. Being able to checkout my master project as a separate branch where I can change whatever I want without risk of screwing everything else up is awesome. But it's not working. Every time I checkout a branch to another branch, make changes to the one branch, and then checkout the original branch, I still have all the files and changes that happened in the other branch. This is getting extremely frustrating. I've read that this can happen when you have files open in the IDE while doing this, but I've been pretty careful about that and both closed the files in the IDE, closed the IDE, and shut down my rails server before switching branches, and this still happens. Also, running 'git clean -f' either deletes everything that happened after some arbitrary commit (and randomly, at that), or, as in the latest case, didn't change anything back to its original state. I thought I was using git correctly, but at this point, I'm at my wit's end here. I'm trying to work with a bunch of experimental code using a stable version of my project, but I keep having to manually track down and fix all the changes I made. Any ideas or suggestions? git checkout -b photo_tagging git branch # to make sure it's right # make a bunch of changes, creations, etc git status # see what's changed since before git add . # approve of the changes, I guess, since if I do git commit after this, it says no changes git commit -m 'these are changes I made' git checkout master git branch #=> *master # look at files, tags_controller is still there, added in photo_tagging # and code added in photo_tagging branch are still there in *master This seems to happen whether I do a commit or not on the branch.

  • Sqlite3 "chained" query

    - by Arrieta
    I need to create a configuration file from a data file that looks as follows: MAN1_TIME '01-JAN-2010 00:00:00.0000 UTC' MAN1_RX 123.45 MAN1_RY 123.45 MAN1_RZ 123.45 MAN1_NEXT 'MAN2' MAN2_TIME '01-MAR-2010 00:00:00.0000 UTC' MAN2_RX 123.45 [...] MAN2_NEXT 'MANX' [...] MANX_TIME [...] This file describes different "legs" of a trajectory. In this case, MAN1 is chained to MAN2, and MAN2 to MANX. In the original file, the chains are not as obvious (i.e., they are non-sequential). I've managed to read the file and store in an Sqlite3 database (I'm using the Python interface). The table is stored with three columns: Id, Par, and Val; for instance, Id='MAN1', Par='RX', and Val='123.45'. I'm interested in querying such database for obtaining the information related to 'n' legs. In English, that would be: "Select RX,RY,RZ for the next five legs starting on MAN1" So the query would go to MAN1, retrieve RX, RY, RZ, then read the parameter NEXT and go to that Id, retrieve RX, RY, RZ; read the parameter NEXT; go to that one ... like this five times. How can I pass such query with "dynamic parameters"? Thank you.

  • Yet another Python Windows CMD mklink problem ... can't get it to work!

    - by Felix Dombek
    OK I have just posted another question which outlined my program but the specific problem was different. Now, my program just stops working without any message whatsoever. I'd be grateful if someone could help me here. I want to create symlinks for each file in a directory structure, all in one large flat folder, and have the following code by now: # loop over directory structure: # for all items in current directory, # if item is directory, recurse into it; # else it's a file, then create a symlink for it def makelinks(folder, targetfolder, cmdprocess = None): if not cmdprocess: cmdprocess = subprocess.Popen("cmd", stdin = subprocess.PIPE, stdout = subprocess.PIPE, stderr = subprocess.PIPE) print(folder) for name in os.listdir(folder): fullname = os.path.join(folder, name) if os.path.isdir(fullname): makelinks(fullname, targetfolder, cmdprocess) else: makelink(fullname, targetfolder, cmdprocess) #for a given file, create one symlink in the target folder def makelink(fullname, targetfolder, cmdprocess): linkname = os.path.join(targetfolder, re.sub(r"[\/\\\:\*\?\"\<\>\|]", "-", fullname)) if not os.path.exists(linkname): try: os.remove(linkname) print("Invalid symlink removed:", linkname) except: pass if not os.path.exists(linkname): cmdprocess.stdin.write("mklink " + linkname + " " + fullname + "\r\n") So this is a top-down recursion where first the folder name is printed, then the subdirectories are processed. If I run this now over some folder, the whole thing just stops after 10 or so symbolic links. Here is the output: D:\Musik\neu D:\Musik\neu\# Electronic D:\Musik\neu\# Electronic\# tag & reencode D:\Musik\neu\# Electronic\# tag & reencode\ChillOutMix D:\Musik\neu\# Electronic\# tag & reencode\Unknown D&B D:\Musik\neu\# Electronic\# tag & reencode\Unknown D&B 2 The program still seems to run but no new output is generated. It created 9 symlinks for some files in the # tag & reencode and the first three files in the ChillOutMix folder. The cmd.exe Window is still open and empty, and shows in its title bar that it is currently processing the mklink command for the third file in ChillOutMix. I tried to insert a time.sleep(2) after each cmdprocess.stdin.write in case Python is just too fast for the cmd process, but it doesn't help. Does anyone know what the problem might be?

  • How to check name of Domino Server to which lotus notes is configured? using C#

    - by Preeti
    Hi, I am trying to login Domino server. For that i am taking Lotus Notes Password and Domino Server Name from user. if (notesPassword == "" && serverName == "") { MessageBox.Show("Please enter the server name !! "); return; } else { if (connectToDomino(notesPassword, serverName)) { MessageBox.Show("Connection Established Succesfully!!.."); } else { MessageBox.Show("Connection Fail.Please Login Again To Begin"); } }//else and in public bool connectToDomino(string NotesPassword, string strDominoServerName) { try { if (_lotesNotesSession == null) { NotesSession notesSession = new Domino.NotesSessionClass(); notesSession.Initialize(NotesPassword); } return true; } catch(Exception ex) { return false; } } Here i am initializing notes password.So in this case it is just verifying Notes Password. So even if user enters invalid entry of server name above function will return true. I tried : string serverName = notesSession.ServerName; But it is showing null value. :( Regards, Preeti

  • Save email as draft in php

    - by Yorian
    Hello, The past few days I've been trying to find out how I can save emails as drafts using php. I've created an emailaddress that uses imap (and resides on the same server). What I would like to do is to use php to create an email and store it in the drafts folder. These emails would then be recognized by the email client (ms office outlook in this case) so they can be editted and send from the email client. I've found some interesting information about the imap functions from php, they let you send mail, but I can't really figure out how to store them in the drafts folder (to which I have write access). I can actually find and read the emails, I save as drafts in my email client, using my ftp connection. However they make use of UID and message-ID's and such which I don't understand where they come from. My questions: - how could I create email drafts - How does a new UID or message-ID get created, and how would I use them for my email-draft file? Help is much appreciated, thanks. Yorian

  • C#/Java: Proper Implementation of CompareTo when Equals tests reference identity

    - by Paul A Jungwirth
    I believe this question applies equally well to C# as to Java, because both require that {c,C}ompareTo be consistent with {e,E}quals: Suppose I want my equals() method to be the same as a reference check, i.e.: public bool equals(Object o) { return this == o; } In that case, how do I implement compareTo(Object o) (or its generic equivalent)? Part of it is easy, but I'm not sure about the other part: public int compareTo(Object o) { if (! (o instanceof MyClass)) return false; MyClass other = (MyClass)o; if (this == other) { return 0; } else { int c = foo.CompareTo(other.foo) if (c == 0) { // what here? } else { return c; } } } I can't just blindly return 1 or -1, because the solution should adhere to the normal requirements of compareTo. I can check all the instance fields, but if they are all equal, I'd still like compareTo to return a value other than 0. It should be true that a.compareTo(b) == -(b.compareTo(a)), and the ordering should stay consistent as long as the objects' state doesn't change. I don't care about ordering across invocations of the virtual machine, however. This makes me think that I could use something like memory address, if I could get at it. Then again, maybe that won't work, because the Garbage Collector could decide to move my objects around. hashCode is another idea, but I'd like something that will be always unique, not just mostly unique. Any ideas?

  • Link to RSS/Atom feed, relative, doesn't work in Firefox

    - by Adrian Smith
    I have a weird problem. I generate a HTML page, hosted let's say at http://www.x.com/stuff which contains <head> <link type="application/atom+xml" rel="alternate" href="/stuff/feed"/> .. </head> The result is: In IE7 all works well - you can click on the feed icon in the browser and the feed is displayed In Firefox, view source, click on the linked /stuff/feed and you see the source of the feed, so that works as expected In Firefox, view the page (not source), then click on the feed icon in the address bar, I get an error that it can't retrieve the URL feed://http//www.x.com/stuff/feed So the problem is, that it's appending feed:// to the front of the URL and then taking out the colon : after the http. I understand that feed: is HTTP anyway so perhaps the adding of that isn't a big problem. But anyway, the fact is, that URL Firefox generates out of my <link> tag doesn't work. I have considered making the URL absolute, but I haven't found any evidence that those URLs have to be absolute, nor can I understand why that would be the case. And for various reasons it would be inconvenient in my code to generate an absolute URL. I can do it if necessary but I would prefer to see proof (e.g. specification, or Mozilla bug report) that it's necessary before making my code messy What do you think? Does anyone know of any evidence that the URL should be absolute? Or am I doing something else wrong? It seems such a simple/obvious tag, where nothing could go wrong, but I can't get it to work.

  • PHP header redirection does nor reload <iframe> in IE

    - by Marco Demaio
    When displaying data from DB usually I'm in this situation I'm in page A.php that shows data from DB, user performs some action (like edit/delete etc) and page B.php is loaded to perform the action, once page B performed the action, it redirects browser to page A, page A is auto reloaded during step (3) therefor it shows an updated situation of the data In order to make page B to redirect to page A i use a simple PHP header("Location: " . "A.php", TRUE, 302); This works well in all situations, except when pages A.php is displaied into an <iframe>: in such a case it does not reload (step 4 does not get done). This seems to happen only in IE7 (don't know about IE8), it works perfectly on FF/Safari. And only when using an <iframe>, if page A.php is not in <iframe> it gest refreshed also in IE7. In order to solve this I simply added a couple of headers in page A.php to set it to not be cached: header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1 header("Expires: Sat, 26 Jul 1997 05:00:00 GMT"); // Date in the past But I was curious if you migt have exeperienced the same issue too in the past, and if you good give me some advises about this. Thanks!

  • Blocking on DBCP connection pool (open and close connnection). Is database connection pooling in OpenEJB pluggable?

    - by topchef
    We use OpenEJB on Tomcat (used to run on JBoss, Weblogic, etc.). While running load tests we experience significant performance problems with handling JMS messages (queues). Problem was localized to blocking on database connection pool getting or releasing connection to the pool. Blocking prevented concurrent MDB instances (threads) from running hence performance suffered 10-fold and worse. The same code used to run on application servers (with their respective connection pool implementations) with no blocking at all. Example of thread blocked: Name: JMS Resource Adapter-worker-23 State: BLOCKED on org.apache.commons.pool.impl.GenericObjectPool@1ea6b4a owned by: JMS Resource Adapter-worker-19 Total blocked: 18,426 Total waited: 0 Stack trace: org.apache.commons.pool.impl.GenericObjectPool.returnObject(GenericObjectPool.java:916) org.apache.commons.dbcp.PoolableConnection.close(PoolableConnection.java:91) - locked org.apache.commons.dbcp.PoolableConnection@1bcba8 org.apache.commons.dbcp.managed.ManagedConnection.close(ManagedConnection.java:147) com.xxxxx.persistence.DbHelper.closeConnection(DbHelper.java:290) .... Couple of questions. I am almost certain that some transactional attributes and properties contribute to this blocking, but MDBs are defined as non-transactional (we use both annotations and ejb-jar.xml). Some EJBs do use container-managed transactions though (and we can observe blocking there as well). Are there any DBCP configurations that may fix blocking? Is DBCP connection pool implementation replaceable in OpenEJB? How easy (difficult) to replace it with another library? Just in case this is how we define data source in OpenEJB (openejb.xml): <Resource id="MyDataSource" type="DataSource"> JdbcDriver oracle.jdbc.driver.OracleDriver JdbcUrl ${oracle.jdbc} UserName ${oracle.user} Password ${oracle.password} JtaManaged true InitialSize 5 MaxActive 30 ValidationQuery SELECT 1 FROM DUAL TestOnBorrow true </Resource>

  • ASP.MVC 2 RTM + ModelState Error at Id property

    - by Zote
    I have this classes: public class GroupMetadata { [HiddenInput(DisplayValue = false)] public int Id { get; set; } [Required] public string Name { get; set; } } [MetadataType(typeof(GrupoMetadata))] public partial class Group { public virtual int Id { get; set; } public virtual string Name { get; set; } } And this action: [HttpPost] public ActionResult Edit(Group group) { if (ModelState.IsValid) { // Logic to save return RedirectToAction("Index"); } return View(group); } That's my view: <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<Group>" %> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <% using (Html.BeginForm()) {%> <fieldset> <%= Html.EditorForModel() %> <p> <input type="submit" value="Save" /> </p> </fieldset> <% } %> <div> <%=Html.ActionLink("Back", "Index") %> </div> </asp:Content> But ModelState is always invalid! As I can see, for MVC validation 0 is invalid, but for me is valid. How can I fix it since, I didn't put any kind of validation in Id property? UPDATE: I don't know how or why, but renaming Id, in my case to PK, solves this problem. Do you know if this an issue in my logic/configuration or is an bug or expected behavior? Thank you

  • "Public" nested classes or not

    - by Frederick
    Suppose I have a class 'Application'. In order to be initialised it takes certain settings in the constructor. Let's also assume that the number of settings is so many that it's compelling to place them in a class of their own. Compare the following two implementations of this scenario. Implementation 1: class Application { Application(ApplicationSettings settings) { //Do initialisation here } } class ApplicationSettings { //Settings related methods and properties here } Implementation 2: class Application { Application(Application.Settings settings) { //Do initialisation here } class Settings { //Settings related methods and properties here } } To me, the second approach is very much preferable. It is more readable because it strongly emphasises the relation between the two classes. When I write code to instantiate Application class anywhere, the second approach is going to look prettier. Now just imagine the Settings class itself in turn had some similarly "related" class and that class in turn did so too. Go only three such levels and the class naming gets out out of hand in the 'non-nested' case. If you nest, however, things still stay elegant. Despite the above, I've read people saying on StackOverflow that nested classes are justified only if they're not visible to the outside world; that is if they are used only for the internal implementation of the containing class. The commonly cited objection is bloating the size of containing class's source file, but partial classes is the perfect solution for that problem. My question is, why are we wary of the "publicly exposed" use of nested classes? Are there any other arguments against such use?

  • Using NHibernate to select entities based on activity of children entities

    - by mannish
    I'm having a case of the Mondays... I need to select blog posts based on recent activity in the post's comments collection (a Post has a List<Comment> property and likewise, a Comment has a Post property, establishing the relationship. I don't want to show the same post twice, and I only need a subset of the entities, not all of the posts. First thought was to grab all posts that have comments, then order those based on the most recent comment. For this to work, I'm pretty sure I'd have to limit the comments for each Post to the first/newest Comment. Last I'd simply take the top 5 (or whatever max results number I want to pass into the method). Second thought would be to grab all of the comments, ordered by CreatedOn, and filter so there's only one Comment per Post. Then return those top (whatever) posts. This seems like the same as the first option, just going through the back door. I've got an ugly, two query option I've got working with some LINQ on the side for filtering, but I know there's a more elegant way to do it in using the NHibernate API. Hoping to see some good ideas here.

  • Method binding to base method in external library can't handle new virtual methods "between"

    - by Berg
    Lets say I have a library, version 1.0.0, with the following contents: public class Class1 { public virtual void Test() { Console.WriteLine( "Library:Class1 - Test" ); Console.WriteLine( "" ); } } public class Class2 : Class1 { } and I reference this library in a console application with the following contents: class Program { static void Main( string[] args ) { var c3 = new Class3(); c3.Test(); Console.ReadKey(); } } public class Class3 : ClassLibrary1.Class2 { public override void Test() { Console.WriteLine("Console:Class3 - Test"); base.Test(); } } Running the program will output the following: Console:Class3 - Test Library:Class1 - Test If I build a new version of the library, version 2.0.0, looking like this: public class Class1 { public virtual void Test() { Console.WriteLine( "Library:Class1 - Test V2" ); Console.WriteLine( "" ); } } public class Class2 : Class1 { public override void Test() { Console.WriteLine("Library:Class2 - Test V2"); base.Test(); } } and copy this version to the bin folder containing my console program and run it, the results are: Console:Class3 - Test Library:Class1 - Test V2 I.e, the Class2.Test method is never executed, the base.Test call in Class3.Test seems to be bound to Class1.Test since Class2.Test didn't exist when the console program was compiled. This was very surprising to me and could be a big problem in situations where you deploy new versions of a library without recompiling applications. Does anyone else have experience with this? Are there any good solutions? This makes it tempting to add empty overrides that just calls base in case I need to add some code at that level in the future...

  • jitter if multiple outliers in ggplot2 boxplot

    - by Andreas
    I am trying to find a suitable display to illustrate various properties within and across school classes. For each class there is only 15-30 data points (pupils). Right now i am leaning towards a whisker-less boxplot, showing only 1.,2. and 3. quartile + datapoints more then e.g. 1 population SD +/- the sample median. This I can do. However - I need to show this graph to some teachers, in order to gauge what they like most. I'd like to compare my graph with a normal boxplot. But the normal boxplot looks the same if there is only one outlier, or e.g. 5 outliers at the same value. In this case this would be a deal-breaker. e.g. test <-structure(list(value = c(3, 5, 3, 3, 6, 4, 5, 4, 6, 4, 6, 4, 4, 6, 5, 3, 3, 4, 4, 4, 3, 4, 4, 4, 3, 4, 5, 6, 6, 4, 3, 5, 4, 6, 5, 6, 4, 5, 5, 3, 4, 4, 6, 4, 4, 5, 5, 3, 4, 5, 8, 8, 8, 8, 9, 6, 6, 7, 6, 9), places = structure(c(1L, 2L, 1L, 1L, 1L, 2L, 1L, 2L, 1L, 2L, 1L, 2L, 2L, 2L, 2L, 2L, 1L, 1L, 2L, 2L, 2L, 1L, 2L, 1L, 1L, 1L, 1L, 2L, 1L, 2L, 1L, 2L, 2L, 2L, 1L, 2L, 1L, 2L, 2L, 1L, 1L, 2L, 2L, 1L, 1L, 1L, 1L, 2L, 1L, 1L, 2L, 2L, 2L, 1L, 1L, 2L, 2L, 1L, 2L, 1L), .Label = c("a", "b"), class = "factor")), .Names = c("value", "places"), row.names = c(NA, -60L), class = "data.frame") ggplot(test, aes(x=places,y=value))+geom_boxplot() Here there are two outliers at ("a",9) - but only one "dot" shown. So my question: How to jitter the outliers. And - what kind of display would you suggest for this kind of data?

  • Access Denied while using System.Diagnostics.Process

    - by Mike C
    I am trying to use the unmanaged ImageMagick library in my ASP.NET application from the command line using System.Diagnostics.Process. Basically, users will upload an .eps file to the site, and then I will run the command line command to convert it into .jpg. This is the code I'm using to try and run the command: Dim proc As New System.Diagnostics.Process proc.StartInfo.RedirectStandardOutput = True proc.StartInfo.RedirectStandardError = True proc.StartInfo.FileName = "C:\Program Files (x86)\ImageMagick-6.6.1-Q16\convert.exe" proc.StartInfo.UseShellExecute = False proc.StartInfo.Arguments = String.Format("{0} {1}", Server.MapPath("~/logo/test.eps"), _ Server.MapPath("~/certificates/temp/test-1234.jpg")) proc.StartInfo.CreateNoWindow = True proc.Start() I am able to run this code just fine on our development Win 2k3 server, but not on our production Win 2k3 Server. I get the error "System.ComponentModel.Win32Exception: Access is denied". The main between the two servers is that the production is 64-bit and runs Plesk to manage multiple domains. I've tried adding rights asp.net user to the ImageMagick directory. The PS Admin says that in the case of Plesk, it's the same account that I use to access the site in VS using FPE. Does anyone know what I might do in order to allow this process to run on my production server? Thanks, Mike

  • iReport / jFreeChart - Combining getItemPaint() override and series colors

    - by barneskd
    I'm attempting to create a bar chart that needs to use specific series colors for N number of categories and a separate color for 1 other category. Here is an example: http://i.imgur.com/1DeCF.png (Sorry, I don't have enough points to embed images yet) In the mockup, Categories 1-3 use a collection of 5 colors to render their series while Category 4 uses a single grey color. My first approach was to override the getItemPaint() method using a customizer class, but I can only figure out how to define a color on the category level, not the series level. Is it possible to define colors on category and/or series levels? Something like, If category != "Category4" Use colors A, B, C, D, and E in category's series Else Use color F in category's series Another thought I had was to combine iReport's Series Colors bar chart property and the getItemPaint() override; that way I could define the 5 colors to use in iReport and use the getItemPaint() override only in the case where the category equals "Category 4". So far I've had no luck combining the two; if the override is defined it overrides iReport's Series Color property.

  • Database Error Handling: What if You have to Call Outside service and the Transaction Fails?

    We all know that we can always wrap our database call in transaction ( with or without a proper ORM), in a form like this: $con = Propel::getConnection(EventPeer::DATABASE_NAME); try { $con->begin(); // do your update, save, delete or whatever here. $con->commit(); } catch (PropelException $e) { $con->rollback(); throw $e; } This way would guarantee that if the transaction fails, the database is restored to the correct status. But the problem is that let's say when I do a transaction, in addition to that transaction, I need to update another database ( an example would be when I update an entry in a column in databaseA, another entry in a column in databaseB must be updated). How to handle this case? Let's say, this is my code, I have three databases that need to be updated ( dbA, dbB, dbc): $con = Propel::getConnection("dbA"); try { $con->begin(); // update to dbA // update to dbB //update to dbc $con->commit(); } catch (PropelException $e) { $con->rollback(); throw $e; } If dbc fails, I can rollback the dbA but I can't rollback dbb. I think this problem should be database independent. And since I am using ORM, this should be ORM independent as well. Update: Some of the database transactions are wrapped in ORM, some are using naked PDO, oledb ( or whatever bare minimum language provided database calls). So my solution has to take care this. Any idea?

  • ASP.NET MVC Strongly Typed Widgets

    - by Ben
    I have developed a plugin system that makes it easy to plug in new logic to an application. Now I need to provide the ability to easily add UI widgets. There are already some good responses on how to create a portal system (like iGoogle) with ASP.NET MVC, and I'm fine about the overall concept. My question is really about how we make strongly typed widgets. Essentially when we set up a widget we define the controller and action names that are used to render that widget. We can use one controller action for widgets that are not strongly typed (since we just return PartialView(widgetControlName) without a model) For widgets that are strongly typed (for example to an IList) we would need to add a new controller action (since I believe it is not possible to use Generics with ActionResult e.g. ActionResult). The important thing is that the widget developers should not change the main application controllers. So my two thoughts are this: Create new controllers in a separate class library Create one partial WidgetController in the main web project and then extend this in other projects (is this even possible?) - not possible as per @mfeingold As far as the development of the widgets (user controls) go, we can just use post build events from our extension projects to copy these into the Views/Widgets directory. Is this a good approach. I am interested to here how others have handled this scenario. Thanks Ben P.S - in case it helps, an example of how we can render widgets - without using Javascript <%foreach (var widget in Model) {%> <%if (widget.IsStronglyTyped) { Html.RenderAction(widget.Action, widget.Controller); } else { Html.RenderPartial(widget.ControlName); } %> <%} %>

  • Is There a Time at which to ignore IDisposable.Dispose?

    - by Mystagogue
    Certainly we should call Dipose() on IDisposable objects as soon as we don't need them (which is often merely the scope of a "using" statement). If we don't take that precaution then bad things, from subtle to show-stopping, might happen. But what about "the last moment" before process termination? If your IDisposables have not been explicitly disposed by that point in time, isn't it true that it no longer matters? I ask because unmanaged resources, beneath the CLR, are represented by kernel objects - and the win32 process termination will free all unmanaged resources / kernel objects anyway. Said differently, no resources will remain "leaked" after the process terminates (regardless if Dispose() was called on lingering IDisposables). Can anyone think of a case where process termination would still leave a leaked resource, simply because Dispose() was not explicitly called on one or more IDisposables? Please do not misunderstand this question: I am not trying to justify ignoring IDisposables. The question is just technical-theoretical. EDIT: And what about mono running on Linux? Is process termination there just as "reliable" at cleaning up unmanaged "leaks?"

  • Why does my adorner not re-render when the element it's applied to changes?

    - by Robert Rossney
    In a UI I'm building, I want to adorn a panel whenever one of the controls in the panel has the focus. So I handle the IsKeyboardFocusWithinChanged event, and add an adorner to the element when it gains the focus and remove the adorner when it loses focus. This seems to work OK. The problem I'm having is that the adorner isn't getting re-rendered if the bounds of the adorned element changes. For instance, in this simple case: <WrapPanel Orientation="Horizontal" IsKeyboardFocusChanged="Panel_IsKeyboardFocusChanged"> <Label>Caption</Label> <TextBox>Data</TextBox> </WrapPanel> the adorner correctly decorates the bounds of the WrapPanel when the TextBox receives the focus, but as I type in text, the TextBox expands underneath the edge of the adorner. Of course as soon as I do anything that forces the adorner to render, like ALT-TAB out of the application or give another panel the focus, it corrects itself. But how can I get it to re-render when the bounds of the adorned element change?

  • Are there some cases where Python threads can safely manipulate shared state?

    - by erikg
    Some discussion in another question has encouraged me to to better understand cases where locking is required in multithreaded Python programs. Per this article on threading in Python, I have several solid, testable examples of pitfalls that can occur when multiple threads access shared state. The example race condition provided on this page involves races between threads reading and manipulating a shared variable stored in a dictionary. I think the case for a race here is very obvious, and fortunately is eminently testable. However, I have been unable to evoke a race condition with atomic operations such as list appends or variable increments. This test exhaustively attempts to demonstrate such a race: from threading import Thread, Lock import operator def contains_all_ints(l, n): l.sort() for i in xrange(0, n): if l[i] != i: return False return True def test(ntests): results = [] threads = [] def lockless_append(i): results.append(i) for i in xrange(0, ntests): threads.append(Thread(target=lockless_append, args=(i,))) threads[i].start() for i in xrange(0, ntests): threads[i].join() if len(results) != ntests or not contains_all_ints(results, ntests): return False else: return True for i in range(0,100): if test(100000): print "OK", i else: print "appending to a list without locks *is* unsafe" exit() I have run the test above without failure (100x 100k multithreaded appends). Can anyone get it to fail? Is there another class of object which can be made to misbehave via atomic, incremental, modification by threads? Do these implicitly 'atomic' semantics apply to other operations in Python? Is this directly related to the GIL?

  • Natural language grammar and user-entered names

    - by Owen Blacker
    Some languages, particularly Slavic languages, change the endings of people's names according to the grammatical context. (For those of you who know grammar or studied languages that do this to words, such as German or Russian, and to help with search keywords, I'm talking about noun declension.) This is probably easiest with a set of examples (in Polish, to save the whole different-alphabet problem): Dorothy saw the cat — Dorota zobaczyla kota The cat saw Dorothy — Kot zobaczyl Dorote It is Dorothy’s cat — To jest kot Doroty I gave the cat to Dorothy — Dalam kota Dorotie I went for a walk with Dorothy — Poszlam na spacer z Dorota “Hello, Dorothy!” — “Witam, Doroto!” Now, if, in these examples, the name here were to be user-entered, that introduces a world of grammar nightmares. Importantly, if I went for Katie (Kasia), the examples are not directly comparable — 3 and 4 are both Kasi, rather than *Kasy and *Kasie — and male names will be wholly different again. I'm guessing someone has dealt with this situation before, but my Google-fu appears to be weak today. I can find a lot of links about natural-language processing, but I don'think that's quite what I want. To be clear: I'm only ever gonna have one user-entered name per user and I'm gonna need to decline them into known configurations — I'll have a localised text that will have placeholders something like {name nominative} and {name dative}, for the sake of argument. I really don't want to have to do lexical analysis of text to work stuff out, I'll only ever need to decline that one user-entered name. Anyone have any recommendations on how to do this, or do I need to start calling round localisation agencies ;o) Further reading (all on Wikipedia) for the interested: Declension Grammatical case Declension in Polish Declension in Russian Declension in Czech nouns and pronouns Disclaimer: I know this happens in many other languages; highlighting Slavic languages is merely because I have a project that is going to be localised into some Slavic languages.
