• Debugging Maya plug-ins: can't get output or debugger to engage

  - by brainjam

  I'm not a total beginner at Maya, but this is my first time trying to write a plug-in for it. I've downloaded the 30-day eval version of Maya2011 (32bit version on 64bit Windows 7), and have tried building a couple of plug-ins with VC 2008 Express. The first one is helloWorldCmd from the sample directory ..\devkit\plug-ins, and it basically doesn't work until you convert the line cout<<"Hello World"<<endl; to cerr<<"Hello World"<<endl;, but I can live with that. The second one is the SelectRingContext2 example from David Gould's book. The plug-in works as advertised, but I cannot get any debugging output from it. I've tried putting cout, cerr,printf, and MGlobal::displayInfo into the doIt() method, and can't get a peep. I also haven't figured out how to run the plug-in in a debugger. I'm afraid I'm missing something easy but slightly obscure, like a flag somewhere. Anybody out there have any hints? Edit: Turns out the action is happening in the redoIt() method. So I can get MGlobal::displayInfo and cerr producing output. Still don't know why cout and printf don't work, and I'm not sure how to run in the debugger. When I run maya -d (which some of the online advice says I should do) it just shows the output window but never loads the rest.

• When does MSBuild set the $(ProjectName) property?

  - by bwerks

  I'm fairly new to MSBuild, and I've done some customization on a Wpf project file that I'm building both in VS2010 and TFS2010. I've customized the output path as follows: <OutputPath Condition=" '$(TeamBuildOutDir)' == '' ">$(SolutionDir)build\binaries\$(ProjectName)\$(Configuration)\$(Platform)</OutputPath> <OutputPath Condition=" '$(TeamBuildOutDir)' != '' ">$(TeamBuildOutDir)binaries\$(ProjectName)\$(Configuration)\$(Platform)</OutputPath> This allows me to build to a centralized binaries directory when building on the desktop, and allows TFS to find the binaries when CI builds are running. However, it seems that in both cases, the $(ProjectDir) property is evaluating to '' at buildtime, which creates strange results. Doing some debugging, it appears as if $(ProjectName) is set by the time BeforeBuild executes, but that my OutputPath property is evaluating it prior to that point. <ProjectNameUsedTooEarly Condition=" '$(ProjectName)' == '' ">true</ProjectNameUsedTooEarly> The preceeding property is in the same property group as my OutputPath property. In the BeforeBuild target, $(ProjectNameUsedTooEarly) evaluates to true, but $(ProjectName) evaluates to the project name as normal by that point. What can I do to ensure that $(ProjectName) has got a value when I use it? edit: I just used Attrice's MSBuild Sidekick to debug through my build file, and in the very first target available for breakpoint (_CheckForInvalidConfigurationAndPlatform) all the properties seem to be set already. ProjectName is already set correctly, but my OutputPath property has already been set using the blank value of ProjectName.

• Convert 4 bytes to int

  - by Oscar Reyes

  I'm reading a binary file like this: InputStream in = new FileInputStream( file ); byte[] buffer = new byte[1024]; while( ( in.read(buffer ) > -1 ) { int a = // ??? } What I want to do it to read up to 4 bytes and create a int value from those but, I don't know how to do it. I kind of feel like I have to grab 4 bytes at a time, and perform one "byte" operation ( like << & FF and stuff like that ) to create the new int What's the idiom for this? EDIT Ooops this turn out to be a bit more complex ( to explain ) What I'm trying to do is, read a file ( may be ascii, binary, it doesn't matter ) and extract the integers it may have. For instance suppose the binary content ( in base 2 ) : 00000000 00000000 00000000 00000001 00000000 00000000 00000000 00000010 The integer representation should be 1 , 2 right? :- / 1 for the first 32 bits, and 2 for the remaining 32 bits. 11111111 11111111 11111111 11111111 Would be -1 and 01111111 11111111 11111111 11111111 Would be Integer.MAX_VALUE ( 2147483647 )

• Data in two databases, eager spool resulting in query

  - by Valkyrie

  I have two databases in SQL2k5: one that holds a large amount of static data (SQL Database 1) (never updated but frequently inserted into) and one that holds relational data (SQL Database 2) related to the static data. They're separated mainly because of corporate guidelines and business requirements: assume for the following problem that combining them is not practical. There are places in SQLDB2 that PKs in SQLDB1 are referenced; triggers control the referential integrity, since cross-database relationships are troublesome in SQL Server. BUT, because of the large amount of data in SQLDB1, I'm getting eager spools on queries that join from the Id in SQLDB2 that references the data in SQLDB1. (With me so far? Maybe an example will help:) SELECT t.Id, t.Name, t2.Company FROM SQLDB1.table t INNER JOIN SQLDB2.table t2 ON t.Id = t2.FKId This query results in a eager spool that's 84% of the load of the query; the table in SQLDB1 has 35M rows, so it's completely choking this query. I can't create a view on the table in SQLDB1 and use that as my FK/index; it doesn't want me to create a constraint based on a view. Anyone have any idea how I can fix this huge bottleneck? (Short of putting the static data in the first db: believe me, I've argued that one until I'm blue in the face to no avail.) Thanks! valkyrie Edit: also can't create an indexed view because you can't put schemabinding on a view that references a table outside the database where the view resides. Dang it.

• How can one setup a version control system on a local network, without a server?

  - by Andrew

  Edit: Ok so I learned that I guess I need an distributed source control, however are there any UI based ones, and do they allow you to merge with other users on the network? This is kind of a two part question, so here it goes. I want to start developing a web application at home (with multiple developers). However, I don't have a dedicated server nor want to pay for on. So first, I don't know which version control system to use for this case, as at work we mostly have TFS setup, so I am not to familiar with whats out there. What are the best free CVS/SVN tools out there? Second, is it possible to somehow setup the CVS/SVN where there is no dedicated server and both clients store up to one week of the source code from the last check-in? Also, it would be helpful if it could integrate with visual studio, again this isn't that important at all. Problem: There are Five users, one is a Server. Server Connected: All Ok Server Disconnected: No one can share. What I am looking for: No Server: Users still have versioning based on version id of last check-in. Users must check all version on network to make sure they aren't outdated based on their last version id. If not check-in, otherwise merge/get latest. If they are update checkin, and set current version id +1.

• How to speed up marching cubes?

  - by Dan Vinton

  I'm using this marching cube algorithm to draw 3D isosurfaces (ported into C#, outputting MeshGeomtry3Ds, but otherwise the same). The resulting surfaces look great, but are taking a long time to calculate. Are there any ways to speed up marching cubes? The most obvious one is to simply reduce the spatial sampling rate, but this reduces the quality of the resulting mesh. I'd like to avoid this. I'm considering a two-pass system, where the first pass samples space much more coarsely, eliminating volumes where the field strength is well below my isolevel. Is this wise? What are the pitfalls? Edit: the code has been profiled, and the bulk of CPU time is split between the marching cubes routine itself and the field strength calculation for each grid cell corner. The field calculations are beyond my control, so speeding up the cubes routine is my only option... I'm still drawn to the idea of trying to eliminate dead space, since this would reduce the number of calls to both systems considerably.

• Automatically resize jQuery UI dialog to the width of the content loaded by ajax

  - by womp

  I'm having a lot of trouble finding specific information and examples on this. I've got a number of jQuery UI dialogs in my application attached to divs that are loaded with .ajax() calls. They all use the same setup call: $(".mydialog").dialog({ autoOpen: false, resizable: false, modal: true }); I just want to have the dialog resize to the width of the content that gets loaded. Right now, the width just stays at 300px (the default) and I get a horizontal scrollbar. As far as I can tell, "autoResize" is no longer an option for dialogs, and nothing happens when I specify it. I'm trying to not write a separate function for each dialog, so .dialog("option", "width", "500") is not really an option, as each dialog is going to have a different width. Specifying width: 'auto' for the dialog options just makes the dialogs take up 100% of the width of the browser window. What are my options? I'm using jQuery 1.4.1 with jQuery UI 1.8rc1. It seems like this should be something that is really easy. EDIT: I've implemented a kludgy workaround for this, but I'm still looking for a better solution.

• Am I under risk of CSRF attacks in a POST form that doesn't require the user to be logged in?

  - by Monika Sulik

  I'm probably being a total noob here, but I'm still uncertain about what a CSRF (Cross-Site Request Forgery) attack is exactly. So lets look at three situations... 1) I have a POST form that I use to edit data on my site. I want this data to be edited only by users that are logged in. 2) I have a site, which can be used by both users who are logged in as well as guests. Parts of the site are for logged in users only, but there are also POST forms that can be used by all users - anonymous and not (for example a standard contact form). Should the contact form be safeguarded against CSRF attacks? 3) I have a site which doesn't have an authentication system at all (well, perhaps that's unrealistic, so lets say it has an admin site which is separate from the rest of it and the admin part is properly safeguarded). The main part of the site is only used by anonymous users. Do the POST forms on it need to be safeguarded? In the case of 1) the answer is clearly yes. But in the case of 2 and 3 I don't know (and is the difference between 2 and 3 even significant?).

• Jquery Livesearch with quicksilver plugin to include not just the <li>s

  - by 133794m3r

  Ok, what i'm trying to do here is to make the exact code found here here ordered list and make it so that it doesn't just not work when i try to add additional elements into the list. Also i'm planning on using the more effecient one linked to at the end but i cannot put it here so you'll have to find that link on your own sadly. Since i'm trying to use this for a knowledge base page i want to allow people to be able to search through the items on the page and go to the proper part(ie loading it into the viewing area) but it's not letting me even include a simple anchor in there. if there is anyway to do something similar or to edit it so that it'll include everything within the <li> that'd be great. I don't know if anyone out there has done something like this before, but if they have and wouldn't mind sharing the code with me i'd be extremely happy. If no one has but does know how to make it include everything within the <li> including text also a great thing to have. I imagine that i won't be the only person out there in this world with my exact query.

• Build failed question - maven - jre or jdk problem

  - by Gandalf StormCrow

  Hi all, I have my JAVA_HOME set to C:\Program Files (x86)\Java\jdk1.6.0_18 After I run maven install I get this message from eclipse: Reason: Unable to locate the Javac Compiler in: C:\Program Files (x86)\Java\jre6\..\lib\tools.jar Please ensure you are using JDK 1.4 or above and not a JRE (the com.sun.tools.javac.Main class is required). In most cases you can change the location of your Java installation by setting the JAVA_HOME environment variable. I'm certain that this is the tricky part Please ensure you are using JDK 1.4 or above and not a JRE When I run configuration its set to JRE6, how do I change it to JDK 1.6 which I have already installed EDIT I even tried to modify the plugin : <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>2.0.2</version> <configuration> <source>1.6</source> <target>1.6</target> <executable>C:\Program Files (x86)\Java\jdk1.6.0_18\bin</executable> </configuration> </plugin> Still I get the same error Maybe I forgot to say I use eclipse maven plugin .. how can I change from JRE to JDK in eclipse ?

• sqrt(int_value + 0.0) -- Does it have a purpose?

  - by Earlz

  Hello, while doing some homework in my very strange C++ book, which I've been told before to throw away, had a very peculiar code segment. I know homework stuff always throws in extra "mystery" to try to confuse you like indenting 2 lines after a single-statement for-loop. But this one I'm confused on because it seems to serve some real-purpose. basically it is like this: int counter=10; ... if(pow(floor(sqrt(counter+0.0)),2) == counter) ... I'm interested in this part especially: sqrt(counter+0.0) Is there some purpose to the +0.0? Is this the poormans way of doing a static cast to a double? Does this avoid some compiler warning on some compiler I do not use? The entire program printed the exact same thing and compiled without warnings on g++ whenever I left out the +0.0 part. Maybe I'm not using a weird enough compiler? Edit: Also, does gcc just break standard and not make an error for Ambiguous reference since sqrt can take 3 different types of parameters? [earlz@EarlzBeta-~/projects/homework1] $ cat calc.cpp #include <cmath> int main(){ int counter=0; sqrt(counter); } [earlz@EarlzBeta-~/projects/homework1] $ g++ calc.cpp /usr/lib/libstdc++.so.47.0: warning: strcpy() is almost always misused, please use strlcpy() /usr/lib/libstdc++.so.47.0: warning: strcat() is almost always misused, please use strlcat() [earlz@EarlzBeta-~/projects/homework1] $

• Add fields to Django ModelForm that aren't in the model

  - by Cyclic

  I have a model that looks like: class MySchedule(models.Model): start_datetime=models.DateTimeField() name=models.CharField('Name',max_length=75) With it comes its ModelForm: class MyScheduleForm(forms.ModelForm): startdate=forms.DateField() starthour=forms.ChoiceField(choices=((6,"6am"),(7,"7am"),(8,"8am"),(9,"9am"),(10,"10am"),(11,"11am"), (12,"noon"),(13,"1pm"),(14,"2pm"),(15,"3pm"),(16,"4pm"),(17,"5pm"), (18,"6pm" startminute=forms.ChoiceField(choices=((0,":00"),(15,":15"),(30,":30"),(45,":45")))),(19,"7pm"),(20,"8pm"),(21,"9pm"),(22,"10pm"),(23,"11pm"))) class Meta: model=MySchedule def clean(self): starttime=time(int(self.cleaned_data.get('starthour')),int(self.cleaned_data.get('startminute'))) return self.cleaned_data try: self.instance.start_datetime=datetime.combine(self.cleaned_data.get("startdate"),starttime) except TypeError: raise forms.ValidationError("There's a problem with your start or end date") Basically, I'm trying to break the DateTime field in the model into 3 more easily usable form fields -- a date picker, an hour dropdown, and a minute dropdown. Then, once I've gotten the three inputs, I reassemble them into a DateTime and save it to the model. A few questions: 1) Is this totally the wrong way to go about doing it? I don't want to create fields in the model for hours, minutes, etc, since that's all basically just intermediary data, so I'd like a way to break the DateTime field into sub-fields. 2) The difficulty I'm running into is when the startdate field is blank -- it seems like it never gets checked for non-blankness, and just ends up throwing up a TypeError later when the program expects a date and gets None. Where does Django check for blank inputs, and raise the error that eventually goes back to the form? Is this my responsibility? If so, how do I do it, since it doesn't evaluate clean_startdate() since startdate isn't in the model. 3) Is there some better way to do this with inheritance? Perhaps inherit the MyScheduleForm in BetterScheduleForm and add the fields there? How would I do this? (I've been playing around with it for over an hours and can't seem to get it) Thanks! [Edit:] Left off the return self.cleaned_data -- lost it in the copy/paste originally

• When and how should independent hierarchies be used in clojure?

  - by Rob Lachlan

  Clojure's system for creating an ad hoc hierarchy of keywords is familiar to most people who have spent a bit of time with the language. For example, most demos and presentations of the language include examples such as (derive ::child ::parent) and they go on to show how this can be used for multi-method dispatch. In all of the slides and presentations that I've seen, they use the global hierarchy. But it is possible to put keyword relationships in independent hierarchies, by using (derive h ::child ::parent), where h is created by (make-hierarchy). Some questions, therefore: Are there any guidelines on when this is useful or necessary? Are there any functions for manipulating hierarchies? Merging is particularly useful, so I do this: (defn merge-h [& hierarchies] (apply merge-with (cons #(merge-with clojure.set/union %1 %2) hierarchies)) But I was wondering if such functions already exist somewhere. EDIT: Changed "custom" hierarchy to "independent" hierarchy, since that term better describes this animal. Also, I've done some research and included my own answer below. Further comments are welcome.

• JVM segmentation faults due to "Invalid memory access of location"

  - by Dan

  I have a small project written in Scala 2.9.2 with unit tests written using ScalaTest. I use SBT for compiling and running my tests. Running sbt test on my project makes the JVM segfault regularly, but just compiling and running my project from SBT works fine. Here is the exact error message: Invalid memory access of location 0x8 rip=0x10959f3c9 [1] 11925 segmentation fault sbt I cannot locate a core dump anywhere, but would be happy to provide it if it can be obtained. Running java -version results in this: java version "1.6.0_37" Java(TM) SE Runtime Environment (build 1.6.0_37-b06-434-11M3909) Java HotSpot(TM) 64-Bit Server VM (build 20.12-b01-434, mixed mode) But I've also got Java 7 installed (though I was never able to actually run a Java program with it, afaik). Another issue that may be related: some of my test cases contain titles including parentheses like ( and ). SBT or ScalaTest (not sure) will consequently insert square parens in the middle of the output. For example, a test case with the name (..)..(..) might suddenly look like (..[)..](..). Any help resolving these issues is much appreciated :-) EDIT: I installed the Java 7 JDK, so now java -version shows the right thing: java version "1.7.0_07" Java(TM) SE Runtime Environment (build 1.7.0_07-b10) Java HotSpot(TM) 64-Bit Server VM (build 23.3-b01, mixed mode) This also means that I now get a more detailed segfault error and a core dump: # # A fatal error has been detected by the Java Runtime Environment: # # SIGSEGV (0xb) at pc=0x000000010a71a3e3, pid=16830, tid=19459 # # JRE version: 7.0_07-b10 # Java VM: Java HotSpot(TM) 64-Bit Server VM (23.3-b01 mixed mode bsd-amd64 compressed oops) # Problematic frame: # V [libjvm.dylib+0x3cd3e3] And the dump.

• Forking in PHP on Windows

  - by Doug Kavendek

  We are running PHP on a Windows server (a source of many problems indeed, but migrating is not an option currently). There are a few points where a user-initiated action will need to kick off a few things that take a while and about which the user doesn't need to know if they succeed or fail, such as sending off an email or making sure some third-party accounts are updated. If I could just fork with pcntl_fork(), this would be very simple, but the PCNTL functions are not available in Windows. It seems the closest I can get is to do something of this nature: exec( 'php-cgi.exe somescript.php' ); However, this would be far more complicated. The actions I need to kick off rely on a lot of context that already will exist in the running process; to use the above example, I'd need to figure out the essential data and supply it to the new script in some way. If I could fork, it'd just be a matter of letting the parent process return early, leaving the child to work on a few more things. I've found a few people talking about their own work in getting various PCNTL functions compiled on Windows, but none seemed to have anything available (broken links, etc). Despite this question having practically the same name as mine, it seems the problem was more execution timeout than needing to fork. So, is my best option to just refactor a bit to deal with calling php-cgi, or are there other options? Edit: It seems exec() won't work for this, at least not without me figuring some other aspect of it, as it waits until the call returns. I figured I could use START, sort of like exec( 'start php-cgi.exe somescript.php' );, but it still waits until the other script finishes.

• Java Error beeping

  - by user1281385

  Im working on a Chat client that i didnt write the bulk of the code for. It works fine however when someone sends a message it beeps (system error beep) when using Java 7. Java 6 and below doesn't have this beep. I cant seem to find whats causing the beep is there any way to find it ? I dont think its calling beep as i have public class nobeep extends sun.awt.windows.WToolkit { @Override public void beep() { System.out.println("tried to beep"); new Exception().printStackTrace(); } } and then called System.setProperty("awt.toolkit", "nobeep"); in the main method. Using the method to send a beep doesnt make it beep. Its only when sent normally. Is there a quick way to track down the cause of the beep ? Edit: After looking in the bugs database - its confirmed. http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7194469 I know it says no work around but is there one (java not c++) or just wait until update 8 ?

• Question about functional OOP style in JavaScript

  - by valums

  I prefer to use functional OOP style for my code (similar to the module pattern) because it helps me to avoid the "new" keyword and all problems with the scope of "this" keyword in callbacks. But I've run into a few minor issues with it. I would like to use the following code to create a class. namespace.myClass = function(){ var self = {}, somePrivateVar1; // initialization code that would call // private or public methods privateMethod(); self.publicMethod(); // sorry, error here function privateMethod(){} self.publicMethod = function(){}; return self; } The problem is that I can't call public methods from my initialization code, as these functions are not defined yet. The obvious solution would be to create an init method, and call it before "return self" line. But maybe you know a more elegant solution? Also, how do you usually handle inheritance with this pattern? I use the following code, butI would like to hear your ideas and suggestions. namespace.myClass2 = function(){ var self = namespace.parentClass(), somePrivateVar1; var superMethod = self.someMethod; self.someMethod = function(){ // example shows how to overwrite parent methods superMethod(); }; return self; } Edit. For those who asked what are the reasons for choosing this style of OOP, you can look into following questions: http://stackoverflow.com/questions/1557386/prototypal-vs-functional-oop-in-javascript http://stackoverflow.com/questions/383402/is-javascript-s-new-keyword-considered-harmful

• MD5 Hashing Given a Key in C#

  - by Jared

  I've been looking for a way to hash a given string in C# that uses a predetermined key. On my adventures through the internet trying to find an example i have seen lots of MD5CryptoServiceProvider examples which seem to use a default key for the machine, but none of them that apply a specific key. I need to have a specific key to encode data as to synchronize it to someone else's server. I hand them a hashed string and an ID number and they use that analyze the data and return a similar set to me. So is there anyway to get md5 to hash via a specific key that would be consistent to both. I would prefer this to be done in C#, but if its not possible with the libraries can you do so with some web languages like php or asp? Edit: Misunderstood the scenario I was thrown into and after a little sitting and thinking about why they would have me use a key it appears they want a key appended to the end of the string and hashed. That way the server can appended the key it has along with the data passed to ensure its a valid accessing computer. Anyways... thanks all ^_^ Edit2: As my comment below says, it was the term 'salting' I was oblivious to. Oh the joys of getting thrown into something new with no directions.

• How can I pass latitude and longitude values from UIViewController to MKMapView?

  - by jerincbus

  I have a detail view that includes three UIButtons, each of which pushes a different view on to the stack. One of the buttons is connected to a MKMapView. When that button is pushed I need to send the latitude and longitude variables from the detail view to the map view. I'm trying to add the string declaration in the IBAction: - (IBAction)goToMapView { MapViewController *mapController = [[MapViewController alloc] initWithNibName:@"MapViewController" bundle:nil]; mapController.mapAddress = self.address; mapController.mapTitle = self.Title; mapController.mapLat = self.lat; mapController.mapLng = self.lng; //Push the new view on the stack [[self navigationController] pushViewController:mapController animated:YES]; [mapController release]; //mapController = nil; } And on my MapViewController.h file I have: #import <UIKit/UIKit.h> #import <MapKit/MapKit.h> #import "DetailViewController.h" #import "CourseAnnotation.h" @class CourseAnnotation; @interface MapViewController : UIViewController <MKMapViewDelegate> { IBOutlet MKMapView *mapView; NSString *mapAddress; NSString *mapTitle; NSNumber *mapLat; NSNumber *mapLng; } @property (nonatomic, retain) IBOutlet MKMapView *mapView; @property (nonatomic, retain) NSString *mapAddress; @property (nonatomic, retain) NSString *mapTitle; @property (nonatomic, retain) NSNumber *mapLat; @property (nonatomic, retain) NSNumber *mapLng; @end And on the pertinent parts of the MapViewController.m file I have: @synthesize mapView, mapAddress, mapTitle, mapLat, mapLng; - (void)viewDidLoad { [super viewDidLoad]; [mapView setMapType:MKMapTypeStandard]; [mapView setZoomEnabled:YES]; [mapView setScrollEnabled:YES]; MKCoordinateRegion region = { {0.0, 0.0 }, { 0.0, 0.0 } }; region.center.latitude = mapLat; //40.105085; region.center.longitude = mapLng; //-83.005237; region.span.longitudeDelta = 0.01f; region.span.latitudeDelta = 0.01f; [mapView setRegion:region animated:YES]; [mapView setDelegate:self]; CourseAnnotation *ann = [[CourseAnnotation alloc] init]; ann.title = mapTitle; ann.subtitle = mapAddress; ann.coordinate = region.center; [mapView addAnnotation:ann]; } But I get this when I try to build: 'error: incompatible types in assignment' for both lat and lng variables. So my questions are am I going about passing the variables from one view to another the right way? And does the MKMapView accept latitude and longitude as a string or a number?

• What AOP tools exist for doing aspect-oriented programming at the assembly language level against x8

  - by JohnnySoftware

  Looking for a tool I can use to do aspect-oriented programming at the assembly language level. For experimentation purposes, I would like the code weaver to operate native application level executable and dynamic link libraries. I have already done object-oriented AOP. I know assembly language for x86 and so forth. I would like to be able to do logging and other sorts of things using the familiar before/after/around constructs. I would like to be able to specify certain instructions or sequences/patterns of consecutive instructions as what to do a pointcut on since assembly/machine language is not exactly the most semantically rich computer language on the planet. If debugger and linker symbols are available, naturally, I would like to be able to use them to identify subroutines' entry points , branch/call/jump target addresses, symbolic data addresses, etc. I would like the ability to send notifications out to other diagnostic tools. Thus, support for sending data through connection-oriented sockets and datagrams is highly desirable. So is normal logging to files, UI, etc. This can be done using the action part of an aspect to make a function call, but then there are portability issues so the tool needs to support a flexible, well-abstracted logging/notifying mechanism with a clean, simple yet flexible. The goal is rapid-QA. The idea is to be able to share aspect source code braodly within communties as well as publicly. So, there needs to be a declarative security policy file that users can share. This insures that nothing untoward that is hidden directly or indirectly in an aspect source file slips by the execution manager. The policy file format needs to be simple to read, write, modify, understand, type-in, edit, and generate. Sort of like Java .policy files. Think the exact opposite of anything resembling XML Schema files and you get the idea. Is there such a tool in existence already?

• How to connect a new query script with SSMS add-in?

  - by squillman

  I'm trying to create a SSMS add-in. One of the things I want to do is to create a new query window and programatically connect it to a server instance (in the context of a SQL Login). I can create the new query script window just fine but I can't find how to connect it without first manually connecting to something else (like the Object Explorer). So in other words, if I connect Obect Explorer to a SQL instance manually and then execute the method of my add-in that creates the query window I can connect it using this code: ServiceCache.ScriptFactory.CreateNewBlankScript( Editors.ScriptType.Sql, ServiceCache.ScriptFactory.CurrentlyActiveWndConnectionInfo.UIConnectionInfo, null); But I don't want to rely on CurrentlyActiveWndConnectionInfo.UIConnectionInfo for the connection. I want to set a SQL Login username and password programatically. Does anyone have any ideas? EDIT: I've managed to get the query window connected by setting the last parameter to an instance of System.Data.SqlClient.SqlConnection. However, the connection uses the context of the last login that was connected instead of what I'm trying to set programatically. That is, the user it connects as is the one selected in the Connection Dialog that you get when you click the New Query button and don't have an Object Explorer connected. EDIT2: I'm writing (or hoping to write) an add-in to automatically send a SQL statement and the execution results to our case-tracking system when run against our production servers. One thought I had was to remove write permissions and assign logins through this add-in which will also force the user to enter a case # canceling the statement if it's not there. Another thought I've just had is to inspect the server name in ServiceCache.ScriptFactory.CurrentlyActiveWndConnectionInfo.UIConnectionInfo and compare it to our list of production servers. If it matches and there's no case # then cancel the query.

• Overriding deep functions in javascript

  - by PintSizedCat

  I'm quite new to javascript but have undertaken a task to get better aquainted with it. However, I am running into some problems with jQuery. The following javascript is the code that is in a third party jQuery plugin and I would love to be able to override the funFunction() function here to do my own implementation. Is this possible, if so, how can I do it? I've been doing a fair amount of searching and have tried a number of methods for overriding the function using things like: jQuery.blah.funFunction = funtion() { alert("like this"); }; Main code: (function($) { $.extend( { blah: new function() { this.construct = = function(settings) { //Construct... stuff }; function funFunction() { //Function I want to override } } }); })(jQuery); For those further interested I am trying to override tablesorter so that the only way a user can sort a column is in ascending order only. Edit: There is a wordpress installation that uses WP-Table-Reloaded which in turn uses this plugin. I don't want to change the core code for this plugin because if there was ever an update I would then have to make sure that my predecessor knew exactly what I had done. I've been programming for a long time and feel like I should easily be able to pick up javascript whilst also looking at jQuery. I know exactly what I need to do for this, just not how I can override this function.

• SIMPLE PHP MVC Framework!

  - by Allen

  I need a simple and basic MVC example to get me started. I dont want to use any of the available packaged frameworks. I am in need of a simple example of a simple PHP MVC framework that would allow, at most, the basic creation of a simple multi-page site. I am asking for a simple example because I learn best from simple real world examples. Big popular frameworks (such as code ignighter) are to much for me to even try to understand and any other "simple" example I have found are not well explained or seem a little sketchy in general. I should add that most examples of simple MVC frameworks I see use mod_rewrite (for URL routing) or some other Apache-only method. I run PHP on IIS. I need to be able to understand a basic MVC framework, so that I could develop my own that would allow me to easily extend functionality with classes. I am at the point where I understand basic design patterns and MVC pretty well. I understand them in theory, but when it comes down to actually building a real world, simple, well designed MVC framework in PHP, i'm stuck. I would really appreciate some help! Edit: I just want to note that I am looking for a simple example that an experienced programmer could whip up in under an hour. I mean simple as in bare bones simple. I dont want to use any huge frameworks, I am trying to roll my own. I need a decent SIMPLE example to get me going.

• HTML onmouseover doesn't work to show up text

  - by REALFREE

  I'm trying to show some information on a picture when onmouseover/onmouseout event occurs. What I want to achieve is something like this website does on top selling. My code is like this: <div class="container" onmouseover="$('#info').css('display','block');" onmouseout="$('#info').css('display','none');"> <img src=..."> <div id="info" style="display:none"> ... some text ... </div> </div> So div info block is initially hidden, but when mouse is on a picture I want the information to appear on corresponding picture (with tint background on the image to see text well). But somewhat it doesn't work. I appreciate any suggestion how to approach this problem. Edit: more precisely, the reason why I choose to use inline because I need to show/hide text corresponding to the image(contain unique div id)that user put their mouse on/out. That means I have many div container and each container has unique div id.
