• Maven doesn't compile target/hibernate3/generated-sources

  - by mmm

  Can someone tell me how to configure maven for it also to compile sources from the target/hibernate3/generated-sources directory? I have already read this and other posts but they don't seem to solve my problem (which indeed seems trivial). I have used the bottom-up approach hibernate configuration for cfg.xml, hbm.xml and POJO generation (i.e. auto-generated the complete hibernate configuration out of an existing database schema). I'm also only using standard maven and hibernate3-plugin directory layouts. Yet, when executing mvn compile in the command-line while my sources are in the src/main/java and the generated sources in /target/hibernate3/generated-sources only the ones from src/main/java get compiled and copied into target/classes. I wouldn't like to generate sources into src/main/java as I'd like mvn clean to clean them. I'd like to solve the problem using command-line, plugins and pom.xml only. Is there a way to configure maven-compiler-plugin to do so? Or is there another way? Regards and thanks for any help.

• Asynchronous daemon processing / ORM interaction with Django

  - by perrierism

  I'm looking for a way to do asynchronous data processing with a daemon that uses Django ORM. However, the ORM isn't thread-safe; it's not thread-safe to try to retrieve / modify django objects from within threads. So I'm wondering what the correct way to achieve asynchrony is? Basically what I need to accomplish is taking a list of users in the db, querying a third party api and then making updates to user-profile rows for those users. As a daemon or background process. Doing this in series per user is easy, but it takes too long to be at all scalable. If the daemon is retrieving and updating the users through the ORM, how do I achieve processing 10-20 users at a time? I would use a standard threading / queue system for this but you can't thread interactions like models.User.objects.get(id=foo) ... Django itself is an asynchronous processing system which makes asynchronous ORM calls(?) for each request, so there should be a way to do it? I haven't found anything in the documentation so far. Cheers

• ASP.NET: aggregating validators in a user control

  - by orsogufo

  I am developing a web application where I would like to perform a set of validations on a certain field (an account name in the specific case). I need to check that the value is not empty, matches a certain pattern and is not already used. I tried to create a UserControl that aggregates a RequiredFieldValidator, a RegexValidator and a CustomValidator, then I created a ControlToValidate property like this: public partial class AccountNameValidator : System.Web.UI.UserControl { public string ControlToValidate { get { return ViewState["ControlToValidate"] as string; } set { ViewState["ControlToValidate"] = value; AccountNameRequiredFieldValidator.ControlToValidate = value; AccountNameRegexValidator.ControlToValidate = value; AccountNameUniqueValidator.ControlToValidate = value; } } } However, if I insert the control on a page and set ControlToValidate to some control ID, when the page loads I get an error that says Unable to find control id 'AccountName' referenced by the 'ControlToValidate' property of 'AccountNameRequiredFieldValidator', which makes me think that the controls inside my UserControl cannot resolve correctly the controls in the parent page. So, I have two questions: 1) Is it possible to have validator controls inside a UserControl validate a control in the parent page? 2) Is it correct and good practice to "aggregate" multiple validator controls in a UserControl? If not, what is the standard way to proceed?

• Converting John Resig's JavaScript Templating Engine to work with PHP Templates

  - by Serhiy

  I'm trying to convert the John Resig's Templating Engine to work with PHP. Essentially what I would like to achieve is the ability to use certain Kohana Views via a JavaScript templating engine, that way I can use the same views for both a standard PHP request and a jQuery AJAX request. I'm starting with the basics and would like to be able to convert http://github.com/nje/jquery-tmpl/blob/master/jquery.tmpl.js To work with php like so... ### From This ### <li><a href="{%= link %}">{%= title %}</a> - {%= description %}</li> ### Into This ### <li><a href="<?= $link ?>"><?= $title ?></a> - <?= description ?></li> The RexEx in it is a bit over my head and it's apparently not as easy as changing the %} to ? in lines 148 to 158. Any help would be highly appreciated. I'm also not sure of how to take care of the $ difference that PHP variables have. Thanks, Serhiy

• JAXB - Beans to XSD or XSD to beans?

  - by bajafresh4life

  I have an existing data model. I would like to express this data model in terms of XML. It looks like I have two options if I'm to use JAXB: Create an XSD that mirrors my data model, and use xjc to create binding objects. Marshalling and unmarshalling will involve creating a "mapping" class that would take my existing data objects and map them to the objects that xjc created. For example, in my data model I have a Doc class, and JAXB would create another Doc class with basically the same exact fields, and I would have to map from my Doc class to xjc's Doc class. Annotate my existing data model with JAXB annotations, and use schemagen to generate an XSD from my annotated classes. I can see advantanges and disadvantages of both approaches. It seems that most people using JAXB start with the XSD file. It makes sense that the XSD should be the gold standard truth, since it expresses the data model in a truly cross-platform way. I'm inclined to start with the XSD first, but it seems icky that I have to write and maintain a separate mapping class that shuttles data in between my world and JAXB world. Any recommendations?

• Creative ways to punish (or just curb) laziness in coworkers

  - by FerretallicA

  Like the subject suggests, what are some creative ways to curb laziness in co-workers? By laziness I'm talking about things like using variable names like "inttheemplrcd" instead of "intEmployerCode" or not keeping their projects synced with SVN, not just people who use the last of the sugar in the coffee room and don't refill the jar. So far the two most effective things I've done both involve the core library my company uses. Since most of our programs are in VB.net the lack of case sensitivity is abused a lot. I've got certain features of the library using Reflection to access data in the client apps, which has a negligible performance hit and introduces case sensitivity in a lot places where it is used. In instances where we have an agreed standard which is compromised by blatant laziness I take it a step further, like the DatabaseController class which will blatantly reject any DataTable passed to it which isn't named dtSomething (ie- must begin with dt and third letter must be capitalised). It's frustrating to have to resort to things like this but it has also gradually helped drill more attention to detail into their heads. Another is adding some code to the library's initialisation function to display a big and potentially embarrassing (only if seen by a client) message advising that the program is running in debug mode. We have had many instances where projects are sent to clients built in debug mode which has a lot of implications for us (especially with regard to error recovery) and doing that has made sure they always build to release before distributing. Any other creative (ie- not StyleCop etc) approaches like this?

• Why does VBA Find loop fail when called from Evaluate?

  - by Abiel

  I am having some problems running a find loop inside of a subroutine when the routine is called using the Application.Evaluate or ActiveSheet.Evaluate method. For example, in the code below, I define a subroutine FindSub() which searches the sheet for a string "xxx". The routine CallSub() calls the FindSub() routine using both a standard Call statement and Evaluate. When I run Call FindSub, everything will work as expected: each matching address gets printed out to the immediate window and we get a final message "Finished up" when the code is done. However, when I do Application.Evaluate "FindSub()", only the address of the first match gets printed out, and we never reach the "Finished up" message. In other words, an error is encountered after the Cells.FindNext line as the loop tries to evaluate whether it should continue, and program execution stops without any runtime error being printed. I would expect both Call FindSub and Application.Evaluate "FindSub()" to yield the same results in this case. Can someone explain why they do not, and if possible, a way to fix this? Thanks. Note: In this example I obviously do not need to use Evaluate. This version is simplified to just focus on the particular problem I am having in a more complex situation. Sub CallSub() Call FindSub Application.Evaluate "FindSub()" End Sub Sub FindSub() Dim rngFoundCell As Range Dim rngFirstCell As Range Set rngFoundCell = Cells.Find(What:="xxx", after:=ActiveCell, LookIn:=xlValues, _ LookAt:=xlPart, SearchOrder:=xlByRows, SearchDirection:=xlNext, _ MatchCase:=False, SearchFormat:=False) If Not rngFoundCell Is Nothing Then Set rngFirstCell = rngFoundCell Do Debug.Print rngFoundCell.Address Set rngFoundCell = Cells.FindNext(after:=rngFoundCell) Loop Until (rngFoundCell Is Nothing) Or (rngFoundCell.Address = rngFirstCell.Address) End If Debug.Print "Finished up" End Sub

• Possible Data Execution Prevention problem in Windows 7

  - by Joel in Gö

  I have a serious problem with my .Net program. It calls a native dll, and then crashes instantly because it can't find a native method. This is behaviour we have seen before, whereby the C# compiler, in its infinite wisdom, sets the flag that the program is DEP compatible, even if it calls a native dll which patently is not. We have the standard workaround for this, where the flag is set to Not DEP Compatible in a post-build step, and this works fine. Everywhere except on my machine. I have Windows 7 32bit, and the program works fine on the Win 7 64bit machines that we have, as well as on Vista and XP; we have not yet been able to check on another Win7 32bit. However, on my machine the DataExecutionPolicy_SupportPolicy is 0, i.e. we have successfully switched DEP off. The dll in question also works fine when called from a native program. We are running out of ideas... any help would be much appreciated!

• Lotus Notes - Export emails to plain text file

  - by mbeckish

  I am setting up a Lotus Notes account to accept emails from a client, and automatically save each email as a plain text file to be processed by another application. So, I'm trying to create my very first Agent in Lotus to automatically export the emails to text. Is there a standard, best practices way to do this? I've created a LotusScript Agent that pretty much works. However, there is a bug - once the Body of the memo exceeds 32K characters, it starts inserting extra CR/LF pairs. I am using Lotus Notes 7.0.3. Here is my script: Sub Initialize On Error Goto ErrorCleanup Dim session As New NotesSession Dim db As NotesDatabase Dim doc As NotesDocument Dim uniqueID As Variant Dim curView As NotesView Dim docCount As Integer Dim notesInputFolder As String Dim notesValidOutputFolder As String Dim notesErrorOutputFolder As String Dim outputFolder As String Dim fileNum As Integer Dim bodyRichText As NotesRichTextItem Dim bodyUnformattedText As String Dim subjectText As NotesItem ''''''''''''''''''''''''''''''''''''''''''''''''''''''' 'INPUT OUTPUT LOCATIONS outputFolder = "\\PASCRIA\CignaDFS\CUser1\Home\mikebec\MyDocuments\" notesInputFolder = "IBEmails" notesValidOutputFolder = "IBEmailsDone" notesErrorOutputFolder="IBEmailsError" ''''''''''''''''''''''''''''''''''''''''''''''''''''''' Set db = session.CurrentDatabase Set curview = db.GetView(notesInputFolder ) docCount = curview.EntryCount Print "NUMBER OF DOCS " & docCount fileNum = 1 While (docCount > 0) 'set current doc to Set doc = curview.GetNthDocument(docCount) Set bodyRichText = doc.GetFirstItem( "Body" ) bodyUnformattedText = bodyRichText.GetUnformattedText() Set subjectText = doc.GetFirstItem("Subject") If subjectText.Text = "LotusAgentTest" Then uniqueID = Evaluate("@Unique") Open "\\PASCRIA\CignaDFS\CUser1\Home\mikebec\MyDocuments\email_" & uniqueID(0) & ".txt" For Output As fileNum Print #fileNum, "Subject:" & subjectText.Text Print #fileNum, "Date:" & Now Print #fileNum, bodyUnformattedText Close fileNum fileNum = fileNum + 1 Call doc.PutInFolder(notesValidOutputFolder) Call doc.RemoveFromFolder(notesInputFolder) End If doccount = doccount-1 Wend Exit Sub ErrorCleanup: Call sendErrorEmail(db,doc.GetItemValue("From")(0)) Call doc.PutInFolder(notesErrorOutputFolder) Call doc.RemoveFromFolder(notesInputFolder) End Sub Update Apparently the 32KB issue isn't consistent - so far, it's just one document that starts getting extra carriage returns after 32K.

• NSBorderlessWindow not responding to CMD-W/CMD-M

  - by Sean

  I have an NSBorderlessWindow subclass of NSWindow with a transparent and non-opaque background (so it's non-rectangular in appearance). I've added my own buttons to function as the close and minimize buttons when I click them, but for some reason the window will not respond to CMD-W or CMD-M like a normal one does. I have my NSWindow subclass set to return YES to canBecomeKeyWindow and canBecomeMainWindow. My NIB still has all the standard menu items in it that are there when you create a new project - including the "Minimize" item in the Window menu with the default shortcut CMD-M defined. It's hooked up to send performMiniaturize: to the first responder. However it is not enabled when the app is run, so it seems like it must be asking the window if it can minimize and the window says no or something. (I'm still very new to OSX/Cocoa.) What am I missing? Also, and maybe this is related, my borderless window has a shadow enabled - but unlike a normal titled window, when I make my window the active/front window by clicking on it, the shadow doesn't change. Normally an OSX focused window has a slightly larger/darker shadow to make it stand out more but mine never changes the shadow. It's like I'm missing something to make the OS treat this window as a real/normal/main window or something and as a result I lose the shadow change and functioning CMD-W/CMD-M.

• How can I process an image in .NET for a full-page print with a quality like Windows Photo Gallery d

  - by Triynko

  I'm writing a printing routing in C#, using the .NET PrintDocument class, handling the OnPrintPage event. I've managed to maximize the margins and print the Image in landscape mode, but it simply does not look as good as when I print the same image file from Windows Photo Gallery (formerly Windows Picture and Fax Viewer), the default image preview program in Windows Vista. I noticed an option there for selecting "Sharpen Image for Printing", but what does that do? I've thought about printing copies of the image from Windows Photo Gallery first, then sending the sheets through the printer a second time to print the custom overlays I need, but it's hard to make it line up every time, since the printer sucks the sheet in without the kind of precision I need... so I really need to do ALL the drawing commands within C#, including the image. Does anyone know how to perform pre-processing on the bitmap so that it prints as nicely as Windows Photo Gallery does it? Are there any simple print drivers that can intercept Photo Gallery printing output as a standard image file (bmp, png, etc.) that can be read by the .NET Image class? I'm all for creativity here.

• ColdFusion 8: Database Connection Reset Error

  - by Gavin

  I have been getting these intermittent ColdFusion Database connection reset errors and was wondering if anyone had experience with this and had a particular solution that worked? Here is the error: Error Executing Database Query.[Macromedia][SQLServer JDBC Driver]A problem occurred when attempting to contact the server (Server returned: Connection reset). Please ensure that the server parameters passed to the driver are correct and that the server is running. Also ensure that the maximum number of connections have not been exceeded for this server. This doesn't happen with any particular query, the code breaks in different queries every time, returning a SQLState error 08s01. These query's logic are fine, no logic errors etc. I checked the network logs and there were no database server connection refusals at the time of the error. Once the first error occurs, it keeps happening for no more than a minute or so at random times of the day, every few days. I've googled this thing and so far anyone that has had this issue was only on CF6 or 7, which the fixes coldFusion put out are only for CF6 or 7. Server configuration wise: The ColdFusion server is version 8 The database server is SQL Server 2005 Standard The database connections allowed setting is set to unlimited on both SQL Server and ColdFusion Any help would be greatly appreciated, Thanks!

• Button Click Event Getting Lost

  - by AlishahNovin

  I have a Menu and Submenu structure in Silverlight, and I want the submenu to disappear when the parent menu item loses focus - standard Menu behavior. I've noticed that the submenu's click events are lost when a submenu item is clicked, because the parent menu item loses focus and the submenu disappears. It's easier to explain with code: ParentMenuBtn.Click += delegate { SubMenu.Visibility = (SubMenu.Visibility == Visibility.Visible) ? SubMenu.Collapsed : SubMenu.Visible; }; ParentMenuBtn.LostFocus += delegate { SubMenu.Visibility = Visibility.Collapsed; }; SubMenuBtn.Click += delegate { throw new Exception("This will never be thrown."); }; In my example, when SubMenuBtn is clicked, the first event that triggers is ParentMenuBtn.LostFocus(), which hides the container of SubMenuBtn. Once the container's visibility collapses, the Click event is never triggered. I'd rather avoid having to hide the sub-menu each time, but I'm a little surprised that the Click event is never triggered as a result... I can't put any checks inside the LostFocus() event to see if my SubMenuBtn has focus, because it does not gain focus until after the LostFocus() event is called. In other words, SubMenuBtn.IsFocused = false when LostFocus() is triggered. Anyone have any thoughts about this?

• Java Playing Cards Game Framework

  - by isme

  My friends and I at uni love playing Shithead into the wee hours. But soon we graduate and will leave town, so probably won't get together for a game for a while. I want to develop a Java app we can use to play Shithead and our other favorites over a network. An app like this already exists, but is ugly, buggy and does not support our house rules. The source is available, but is such a mess that I would really rather start from scratch than try to refactor it! Building my game using some standard playing card api or framework, if such a thing exists, would be better than starting from scratch. The answer to a similar SO question was to use the JPC-API, which allegedly provides basic playing card services and rendering. But this Sourceforge project currently makes available no files or source code! Is there an alternative, or somewhere else to find this framework? Soon I will need help with the following as well: Lobby services (finding other players) Gaming network protocol (to communicate moves between players) Gaming theory (to write the computer opponent) Winning condition detection Game UI development

• Smack API giving error while logging into Tigase Server setup locally

  - by Ameya Phadke

  Hi, I am currently developing android XMPP client to communicate with the Tigase server setup locally.Before starting development on Android I am writing a simple java code on PC to test connectivity with XMPP server.My XMPP domain is my pc name "mwbn43-1" and administrator username and passwords are admin and tigase respectively. Following is the snippet of the code I am using class Test { public static void main(String args[])throws Exception { System.setProperty("smack.debugEnabled", "true"); XMPPConnection.DEBUG_ENABLED = true; ConnectionConfiguration config = new ConnectionConfiguration("mwbn43-1", 5222); config.setCompressionEnabled(true); config.setSASLAuthenticationEnabled(true); XMPPConnection con = new XMPPConnection(config); // Connect to the server con.connect(); con.login("admin", "tigase"); Chat chat = con.getChatManager().createChat("aaphadke@mwbn43-1", new MessageListener() { public void processMessage(Chat chat, Message message) { // Print out any messages we get back to standard out. System.out.println("Received message: " + message); } }); try { chat.sendMessage("Hi!"); } catch (XMPPException e) { System.out.println("Error Delivering block"); } String host = con.getHost(); String user = con.getUser(); String id = con.getConnectionID(); int port = con.getPort(); boolean i = false; i = con.isConnected(); if (i) System.out.println("Connected to host " + host + " via port " + port + " connection id is " + id); System.out.println("User is " + user); con.disconnect(); } } When I run this code I get following error Exception in thread "main" Resource binding not offered by server: at org.jivesoftware.smack.SASLAuthentication.bindResourceAndEstablishSession(SASLAuthenticatio n.java:416) at org.jivesoftware.smack.SASLAuthentication.authenticate(SASLAuthentication.java:331) at org.jivesoftware.smack.XMPPConnection.login(XMPPConnection.java:395) at org.jivesoftware.smack.XMPPConnection.login(XMPPConnection.java:349) at Test.main(Test.java:26) I found this articles on the same problem but no concrete solution here Could anyone please tell me the solution for this problem.I checked the XMPPConnection.java file in the Smack API and it looks the same as given in the link solution.

• Running multiple instances of tomcat in eclipse WTP

  - by lisak

  Hey, SCENARIO: 10 CATALINA_BASEs with own configuration (always the same port numbers 8080, but 10 different IP/hostnames on one host via virtual IPs). created a server in WTP and pick "Use the custom location" option in the server configuration in eclipse. New configuration files are created in workspace/Server/server-name-config/ Set up the server path and deploy path for my catalina base (not the internal .metadata one) After I started it, the new configuration files overwrote the original catalina-base/conf files I had there - I was glad, it should be like this but after I made changes in the eclipse config files workspace/Server/server-name-config/ and restarted the server, the changes didn't appeared in the original files in CATALINA_BASE/conf What the hell is that ? So I set the CATALINA_BASE/conf/server.xml to fault configuration and restarted tomcat from eclipse and it worked ! it took the configuration from /Server/server-name-config/server.xml Then I deleted CATALINA_BASE/conf/server.xml and it said that there is no server.xml in catalina base ! How is it possible ? I don't understand why eclipse WTP developers made so tight integration. There should by just symbolic links in /Server/server-name-config/ pointing to CATALINA_BASE/conf/ ... now there is a weird system which is totally unpredictable. The changes in /Server/server-name-config/ are not reflected in CATALINA_BASE/conf ... from where the standard bootstrap.jar or other catalina classloaders and classes build server, engine and other objects with particular setting. Moreover the CATALINA_BASEs could be used outside eclipse then. The second problem, I'm setting up various things in CATALINA_BASE/bin/startup.sh and setenv.sh which is easy cause I can use bash for it. Is then modifying VM parameters in the "Open launch configuration" settings the only way how to do it in eclipse ? Sorry for such a huge pile of questions, but I'm annoyed by the fact that it is much better to not use eclipse WTP for this because it is very poorly designed and it's a shame because this would spare me a lot of time. And using the internal .metadata/ instances it's even more terrifying way that the one I described.

• [NSFetchedResultsController sections] returns nil?

  - by Chris

  Hi Everyone, I am trying to resolve this for days at this stage and I'm hoping you can help. I have two ViewControllers which query two different tables from the same database using Core Data. The first ViewController is opened with the app and displays fine. The second is called from within the first ViewController, using a pretty standard fetch setup: - (NSFetchedResultsController *)fetchedClients { // Set up the fetched results controller if needed. if (fetchedClients == nil) { // Create the fetch request for the entity. NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init]; // Edit the entity name as appropriate. NSEntityDescription *entity = [NSEntityDescription entityForName:@"Clients" inManagedObjectContext:managedObjectContext]; [fetchRequest setEntity:entity]; // Edit the sort key as appropriate. NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"clientsName" ascending:YES]; NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:sortDescriptor, nil]; [fetchRequest setSortDescriptors:sortDescriptors]; // Edit the section name key path and cache name if appropriate. // nil for section name key path means "no sections". NSFetchedResultsController *aFetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:fetchRequest managedObjectContext:managedObjectContext sectionNameKeyPath:nil cacheName:@"Root"]; aFetchedResultsController.delegate = self; self.fetchedClients = aFetchedResultsController; [aFetchedResultsController release]; [fetchRequest release]; [sortDescriptor release]; [sortDescriptors release]; } return fetchedClients; } When I call [self.fetchedClients sections], I get a nil (0x0) return. I have examined the database using an external application to ensure data exists in the "Clients" table. Can anyone think of a reason why [self.fetchedClients sections] would return nil? Many thanks for any help you can provide. Regards, Chris

• JVM/CLR Source-compatible Language Options

  - by Nathan Voxland

  I have an open source Java database migration tool (http://www.liquibase.org) which I am considering porting to .Net. The majority of the tool (at least from a complexity side) is around logic like "if you are adding a primary key and the database is Oracle use this SQL. If database is MySQL use this SQL. If the primary key is named and the database is Postgres use this SQL". I could fork the Java codebase and covert it (manually and/or automatically), but as updates and bug fixes to the above logic come in I do not want to have to apply it to both versions. What I would like to do is move all that logic into a form that can be compiled and used by both Java and .Net versions naively. The code I am looking to convert does not contain any advanced library usage (JDBC, System.out, etc) that would vary significantly from Java to .Net, so I don't think that will be an issue (at worst it can be designed around). So what I am looking for is: A language in which I can code common parts of my app in and compile it into classes usable by the "standard" languages on the target platform Does not add any runtime requirements to the system Nothing so strange that it scares away potential contributors I know Python and Ruby both have implementations on for the JVM and CLR. How well do they fit my requirements? Has anyone been successful (or unsuccesful) using this technique for cross-platform applications? Are there any gotcha's I need to worry about?

• PLKs and Web Service Software Factory

  - by Nix

  We found a bug in Web Service Software Factory a description can be found here. There has been no updates on it so we decided to download the code and fix it ourself. Very simple bug and we patched it with maybe 3 lines of code. However* we have now tried to repackage it and use it and are finding that this is seemingly an impossible process. Can someone please explain to me the process of PLKs? I have read all about them but still don't understand what is really required to distribute a VS package. I was able to get it to load and run using a PLK obtained from here, but i am assuming that you have to be a partner to get a functional PLK that will be recognized on other peoples systems? Every time i try and install this on a different computer I get a "Package Load Failure". Is the reason I am getting errors because I am not using a partner key? Is there any other way around this? For instance is there any way we can have an "internal" VS package that we can distribute? Edit Files I had to change to get it to work. First run devenv PostInstall.proj Generate your plks and replace ##Package PLK## (.resx files) --Just note that package version is not the class name but is "Web Service Software Factory: Modeling Edition" -- And you need to remove the new lines from the key ProductDefinitionRegistryFragment.wxi line 1252(update version to whatever version you used in plk) Uncomment all // [VSShell::ProvideLoadKey("Standard", Constant in .tt files.

• ASP.NET Emails blocked by Spam filter on Exchange

  - by Amadiere

  I'm trying to send an email via some C# ASP.NET code. This is being sent to our internal mailrelay server, with our standard "from" address (e.g. [email protected]). In some instances, this is getting through OK, in others, it's getting blocked by the Spam Filter. An example of our Web.config <mailSettings> <smtp from="[email protected]"> <network host="mailrelay.domain.com" defaultCredentials="true" /> </smtp> </mailSettings> I've spoken with our Exchange Server team and they inform me that on occasions, our mail looks sufficiently like spam and is automatically blocked. The algorithm appears to be points based and blocks on a score of 45. 20 points are instantly added because our system is not sending the hostname with the domain name suffixed. e.g. the server is hoping for myServerName.domain.com, but despite being part of that domain, the server is sending from myServerName. I've been asked to look at altering the EHLO string that is sent and/or influencing the host so that it is its fully qualified name. However, this makes little sense to me, and although I understand the concept of what I need to change - I don't know where to begin looking for the fix.

• rails best practices where to place unobtrusive javascript

  - by nathanvda

  Hi there, my rails applications (all 2.3.5) use a total mix of inline javascript, rjs, prototype and jquery. Let's call it learning or growing pains. Lately i have been more and more infatuated with unobtrusive javascript. It makes your html clean, in the same way css cleaned it up. But most examples i have seen are small examples, and they put all javascript(jquery) inside application.js Now i have a pretty big application, and i am thinking up ways to structure my js. I like somehow that my script is still close to the view, so i am thinking something like orders.html.erb orders.js where orders.js contains the unobtrusive javascript specific to that view. But maybe that's just me being too conservative :) I have read some posts by Yehuda Katz about this very problem here and here, where he tackles this problem. It will go through your js-files and only load those relevant to your view. But alas i can't find a current implementation. So my questions: how do you best structure your unobtrusive javascript; manage your code, how do you make sure that it is obvious from the html what something is supposed to do. I guess good class names go a long way :) how do you arrange your files, load them all in? just a few? do you use content_for :script or javascript_include_tag in your view to load the relevant scripts. Or ... ? do you write very generic functions (like a delete), with parameters (add extra attributes?), or do you write very specific functions (DRY?). I know in Rails 3 there is a standard set, and everything is unobtrusive there. But how to start in Rails 2.3.5? In short: what are the best practices for doing unobtrusive javascript in rails? :)

• Access SSAS cube from across domains without direct database connection

  - by SuperKing

  Hello, I'm working with SQL Server Analysis Services for the first time and have the dilemma of working on a project in which users must be able to access SSAS Cubes (via a custom web dashboard) that live across different servers and domains, but without having access to the other server's SSAS database connection strings. So Organization A and Organization B will have their own cubes on their own servers, but Organization A users must be able to view Organization B's cubes, and Organization B users must be able to view Organization A's cubes, but neither organization should have access to the connection string. I've read about allowing HTTP access to the SSAS server and cube from the link below, but that requires setting up users for authentication or allowing anonymous access to one organization's server for users of another organization, and I'm not sure this would be acceptable for this situation, or if this is the preferred way to do this. Is performance acceptable here? http://technet.microsoft.com/en-us/library/cc917711.aspx I also wonder if perhaps it makes sense to run a nightly/weekly process that accesses the other organization's SSAS database via a web service or something, and pull that data into a database on the organization's server, and then rebuild the cube. Then that cube would be queried without having to go and connect to the other organization server when viewing the cube. Has anyone else attempted to accomplish something similar? Is HTTP access the standard way to go for this? Or any other possible options? Thanks, and please let me know if you need more info, still unclear on how some of this works.

• Simple, fast SQL queries for flat files.

  - by plinehan

  Does anyone know of any tools to provide simple, fast queries of flat files using a SQL-like declarative query language? I'd rather not pay the overhead of loading the file into a DB since the input data is typically thrown out almost immediately after the query is run. Consider the data file, "animals.txt": dog 15 cat 20 dog 10 cat 30 dog 5 cat 40 Suppose I want to extract the highest value for each unique animal. I would like to write something like: cat animals.txt | foo "select $1, max(convert($2 using decimal)) group by $1" I can get nearly the same result using sort: cat animals.txt | sort -t " " -k1,1 -k2,2nr And I can always drop into awk from there, but this all feels a bit awkward (couldn't resist) when a SQL-like language would seem to solve the problem so cleanly. I've considered writing a wrapper for SQLite that would automatically create a table based on the input data, and I've looked into using Hive in single-processor mode, but I can't help but feel this problem has been solved before. Am I missing something? Is this functionality already implemented by another standard tool? Halp!

• updating changes from one database to another database in the same server

  - by Pavan Kumar

  I have a copy of client database say 'DBCopy' which already contains modified data. The copy of the client database (DBCopy) is attached to the SQL Server where the Central Database (DBCentral) exists. Then I want to update whatever changes already present in DBCopy to DBCentral. Both DBCopy and DBCentral have same schema. How can i do it programatically using C#.NET maybe with a button click. Can you give me an example code as how to do it?. I am using SQL Server 2005 Standard Edition and VS 2008 SP1. In the actual scenario there are about 7 client database all with same schema as the central database. I am bringing copy of each client database and attach it to Central Server where the central database resides and try to update changes present in each copy of the client database to central database one by one programatically using C# .NET . The clients and the central server are physically seperate machines present in different places. They are not interconnected. I need to only update and insert new data. I am not bothered about deletion of data. Thanks and regards Pavan

• Java: Handling cookies when logging in with POST

  - by Cris Carter

  I'm having quite some trouble logging in to any site in Java. I'm using the default URLconnection POST request, but I'm unsure how to handle the cookies properly. I tried this guide: http://www.hccp.org/java-net-cookie-how-to.html But couldn't get it working. I've been trying basically for days now, and I really need help if anyone wants to help me. I'll probably be told that it's messy and that I should use a custom library meant for this stuff. I tried downloading one, but wasn't sure how to get it set up and working. I've been trying various things for hours now, and it just won't work. I'd rather do this with a standard URLconnection, but if anyone can help me get another library working that's better for this, that would be great, too. I would really appreciate if someone could post a working source that I could study. What I need is: POST login data to site - Get and store the cookie from the site - use cookie with next URLconnection requests to get logged-in version of the site. Can anyone help me with this? Would be EXTREMELY appreciated. It really does mean a lot. If anyone wants to actually help me out live, please leave an instant-messenger address. Thank you a lot for your time.
