  • Microsoft.Build.Engine Error (default targets): Target GetFrameworkPaths: Could not locate the .NET

    - by Mitchan Adams
    I am writing a webservice, that when called should build a C# project. I'm using the framework 2 reference, Microsoft.Buld.Engine and Microsoft.Build.Framework. If you look under the '<Import>' section .csproj file, by default it has: <Import Project="$(MSBuildToolsPath)\Microsoft.CSharp.targets" /> which I then changed to: <Import Project="$(MSBuildBinPath)\Microsoft.CSharp.targets" /> My code to build the csproj is: Engine buildEngine = new Engine(Path.Combine(Environment.GetEnvironmentVariable("SystemRoot"), @"Microsoft.NET\Framework\v2.0.50727")); FileLogger logger = new FileLogger(); logger.Parameters = @"logfile=c:\temp\build.log"; buildEngine.RegisterLogger(logger); bool success = buildEngine.BuildProjectFile([Path_Of_Directory]+ "ProjectName.csproj"); buildEngine.UnregisterAllLoggers(); The success variable returns a false because the build faild. I then check the build.log file and this is the error I recieve: *Build started 3/17/2010 11:16:56 AM. ______________________________ Project "[Path_Of_Directory]\ProjectName.csproj" (default targets): Target GetFrameworkPaths: Could not locate the .NET Framework SDK. The task is looking for the path to the .NET Framework SDK at the location specified in the SDKInstallRootv2.0 value of the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft.NETFramework. You may be able to solve the problem by doing one of the following: 1.) Install the .NET Framework SDK. 2.) Manually set the above registry key to the correct location. Target* I cant understand why it wont build. Any help will be much appreciated. Thanks

  • GeoDjango: Exceptions for basic geographic queries

    - by omat
    I am having problems with geographic queries with GeoDjango running on SpatiaLite on my development environment. from django.contrib.gis.db import models class Test(models.Model): poly = models.PolygonField() point = models.PointField() geom = models.GeometryField() objects = models.GeoManager() Testing via shell: >>> from geotest.models import Test >>> from django.contrib.gis.geos import GEOSGeometry >>> >>> point = GEOSGeometry("POINT(0 0)") >>> point <Point object at 0x105743490> >>> poly = GEOSGeometry("POLYGON((0 0, 0 1, 1 1, 1 0, 0 0))") >>> poly <Polygon object at 0x105743370> >>> With these definitions, lets try some basic geographic queries. First contains: >>> Test.objects.filter(point__within=poly) Assertion failed: (0), function appendGeometryTaggedText, file WKTWriter.cpp, line 228. Abort trap And the django shell dies.

  • C++ Swig Python (Embedded Python in C++) works in Release but not in Debug

    - by sambha
    Platform: Windows 7, 64 bit (x64), Visual Studio 2008 I chose Python & Swig binding as the scripting environment of the application. As a prototype, created a simple VS solution with main() which initializes Python (Py_Initalize, Py_setPyHome, etc) & executes test.py. In the same solution created another project which is a DLL of a simple class. Used SWIG to wrap this class. This DLL is the _MyClasses.pyd. test.py creates the objects of my class & calls its member functions. All this works like a charm in the Release mode. But does not work in Debug mode (even tried banging my head on the laptop ;-) ). Output of my work looks like this (in both release & debug): x64 -debug - _MyClasses.pyd - MyClasses.py - test.exe - test.py - python26.dll - python26_d.dll Note that the debug version is linked against python26_d.lib. Had to build python myself for this! test.py import MyClasses print "ello" m = MyClasses.Male("John Doe", 25) print m.getType() Male is the C++ class. The problem: Traceback (most recent call last): File "test.py", line 6, in <module> import MyClasses File "...\x64\Debug\MyClasses.py", line 25, in <module> _MyClasses = swig_import_helper() File "...\x64\Debug\MyClasses.py", line 17, in swig_imp ort_helper import _MyClasses ImportError: No module named _MyClasses [15454 refs] I am used to Makefiles & am new to Visual Studio. I dont know who the culprit is here: Swig, The debug build of Python, Visual Studio, my stupidity. Thank you in advance. It will be a great help.

  • How to manage a One-To-One and a One-To-Many of same type as unidirectional mapping?

    - by user1652438
    I'm trying to implement a model for private messages between two or more users. That means I've got two Entities: User PrivateMessage The User model shouldn't be edited, so I'm trying to set up an unidirectional relationship: @Entity (name = "User") @Table (name = "user") public class User implements Serializable { @Id String username; String password; // something like this ... } The PrivateMessage Model addresses multiple receivers and has exactly one sender. So I need something like this: @Entity (name = "PrivateMessage") @Table (name = "privateMessage") @XmlRootElement @XmlType (propOrder = {"id", "sender", "receivers", "title", "text", "date", "read"}) public class PrivateMessage implements Serializable { private static final long serialVersionUID = -9126766942868177246L; @Id @GeneratedValue private Long id; @NotNull private String title; @NotNull private String text; @NotNull @Temporal(TemporalType.TIMESTAMP) private Date date; @NotNull private boolean read; @NotNull @ElementCollection(fetch = FetchType.EAGER, targetClass = User.class) private Set<User> receivers; @NotNull @OneToOne private User sender; // and so on } The according 'privateMessage' table won't be generated and just the relationship between the PM and the many receivers is satisfied. I'm confused about this. Everytime I try to set a 'mappedBy' attribute, my IDE marks it as an error. It seems to be a problem that the User-entity isn't aware of the private message which maps it. What am I doing wrong here? I've solved some situation similar to this one, but none of those solutions will work here. Thanks in advance!

  • I do I iterate the records in a database using LINQ when I have already built the LINQ DB code?

    - by Seth Spearman
    I asked on SO a few days ago what was the simplest quickest way to build a wrapper around a recently completed database. I took the advice and used sqlmetal to build linq classes around my database design. Now I am having two problems. One, I don't know LINQ. And, two, I have been shocked to realize how hard it is to learn. I have a book on LINQ (Linq In Action by Manning) and it has helped some but at the end of the day it is going to take me a couple of weeks to get traction and I need to make some progress on my project today. So, I am looking for some help getting started. Click HERE To see my simple database schema. Click HERE to see the vb class that was generated for the schema. My needs are simple. I have a console app. The main table is the SupplyModel table. Most of the other tables are child tables of the SupplyModel table. I want to iterate through each of Supply Model records. I want to grab the data for a supply model and then DoStuff with the data. And I also need to iterate through the child records, for each supply model, for example the NumberedInventories and DoStuff with that as well. I want to only iterate the SupplyModels that are have IDs that are in an array of strings containing the IDs. I need help doing this in VB rather than C# if possible. Thanks for your help. Seth

  • HTTP Basic authentication using Authlogic or authenticate_or_request_with_http_basic for API call?

    - by Gaius Parx
    I have a Rails 2.3.x app that implements the act_as_authentic in User model and a UserSession model as per Authlogic Github example. I am implementing an API to allow access from iPhone. Will be using HTTP Basic authentication via https (will not implement single access token). Each API call requires a username/password for the access. I am able to access the API by calling http://username:password@localhost:3000/books.xml for example. Authlogic will not persist if using the single access token. But I am using HTTP Basic which I think Authlogic will create session for the API calls, which is not used for my API methods. So for each API call I made, new session object is created. Thus appear to me that this would load up the server resource pretty quickly. Sounds like a bad idea. The alternative is to use the Rails authenticate_or_request_with_http_basic for API controllers. Example adding a before_filter: def require_http_auth_user authenticate_or_request_with_http_basic do |username, password| if @current_user = User.find_by_email(username) @current_user.valid_password?(password) else false end end end This will bypass the Authlogic UserSession and just use the User model. But this will involve using separate authentication codes in the app. Anyone has any comments and can share their experience? Thanks

  • How do I pass a callback function to sqlite3_exec on iOS 5.1?

    - by John Doh
    I am new to both xcode/iOS/Objective-C and sqlite. I am trying to teach myself the basics - and I would like to use the sqlite3 wrapper "sqlite3_exec" for a select query. For some reason, I can't find a simple example anywhere of someone doing this. Basically, the method has a parameter (the third one) for a callback function: int sqlite3_exec( sqlite3*, /* An open database */ const char *sql, /* SQL to be evaluated */ int (*callback)(void*,int,char**,char**), /* Callback function */ void *, /* 1st argument to callback */ char **errmsg /* Error msg written here */ ); That's fine. I'm no stranger to callbacks. However, I just can't seem to get the syntax down right. I took over one of the view controllers in my iPad (iOS 5.1) xcode (4.3) project, and made the changes shown below: #import "SecondViewController.h" #import "sqlite3.h" #import "AppState.h" @interface SecondViewController () @end @implementation SecondViewController - (int)myCallback:(void *)a_parm argc:(int)argc argv:(char **)argv column:(char **)column { return 0; } - (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view, typically from a nib. //grab questionnaire names char *sql = "select * from QST2Main order by [Name]"; char *err = nil; sqlite3 *db = [[AppState sharedManager] getgCn]; sqlite3_exec(db, sql, myCallback, nil, &err); } Essentially, I want to run a query when this view first loads, to store some data for later use. But, XCode doesn't like the "myCallback" usage at the bottom there. It says: Undeclared Use of Identifier 'myCallback.' That method is declared in the header file, and I've even tried making it static. Nothing seems to make this error go away. I know I must be doing something fundamentally wrong here, but for the life of me I can't figure out what - I can't even find other code samples in this area that could help me figure out what I'm missing. Many thanks!

  • How to limit speed with BMW JSDK on 116i?

    - by lexicore
    I'm experimenting with the BMW Java SDK on the new BMW 116i Innovation Package. Basic things like turning the lights on and off, starting and stopping the motor work fine. What I'm trying to do now is that to write a carlet which would limit the speed to the maximum configured in the driver profile. Driver identity will be detected as usual via RFID reader. My problem is that though I can read the speed from the tachometer, I can't really limit the speed. Here's what I've got working so far: public class SpeenControllingCarlet extends GenericCarlet { public void start(final VehicleModel model) throws CarletException { RfidReader rfidReader = (RfidReader) model .getDevice(Devices.DRIVER_RFID_READER); Rfid rfid = rfidReader.getRfid(); DriverProfile driverProfile = model.getDriverProfileRegistry() .getDriverProfile(rfid.toString()); if (driverProfile == null) { return; } final Double maxAllowedSpeed = Double.valueOf(driverProfile .getCustomAttribute("maxAllowedSpeed", "190")); Tachometer tachometer = (Tachometer) mode.getDevice(Devices.TACHOMETER); tachometer.addSpeedListener(new SpeedListener() { public void onSpeedChanged(SpeedChangedEvent speedChangedEvent) { if (speedChangedEvent.getCurrentSpeed() > maxAllowedSpeed) { Horn horn = (Horn) mode.getDevice(Devices.HORN); horn.beep(440, 2000); } } }); } } This will just beep for two seconds if the driver goes faster than the driver profile allows. My question is - is there a possibility to actually limit the speed (not just silly beeping)?

  • Optimizing code using PIL

    - by freakazo
    Firstly sorry for the long piece of code pasted below. This is my first time actually having to worry about performance of an application so I haven't really ever worried about performance. This piece of code pretty much searches for an image inside another image, it takes 30 seconds to run on my computer, converting the images to greyscale and other changes shaved of 15 seconds, I need another 15 shaved off. I did read a bunch of pages and looked at examples but I couldn't find the same problems in my code. So any help would be greatly appreciated. From the looks of it (cProfile) 25 seconds is spent within the Image module, and only 5 seconds in my code. from PIL import Image import os, ImageGrab, pdb, time, win32api, win32con import cProfile def GetImage(name): name = name + '.bmp' try: print(os.path.join(os.getcwd(),"Images",name)) image = Image.open(os.path.join(os.getcwd(),"Images",name)) except: print('error opening image;', name) return image def Find(name): image = GetImage(name) imagebbox = image.getbbox() screen = ImageGrab.grab() #screen = Image.open(os.path.join(os.getcwd(),"Images","Untitled.bmp")) YLimit = screen.getbbox()[3] - imagebbox[3] XLimit = screen.getbbox()[2] - imagebbox[2] image = image.convert("L") Screen = screen.convert("L") Screen.load() image.load() #print(XLimit, YLimit) Found = False image = image.getdata() for y in range(0,YLimit): for x in range(0,XLimit): BoxCoordinates = x, y, x+imagebbox[2], y+imagebbox[3] ScreenGrab = screen.crop(BoxCoordinates) ScreenGrab = ScreenGrab.getdata() if image == ScreenGrab: Found = True #print("woop") return x,y if Found == False: return "Not Found" cProfile.run('print(Find("Login"))')

  • python: nonblocking subprocess, check stdout

    - by Will Cavanagh
    Ok so the problem I'm trying to solve is this: I need to run a program with some flags set, check on its progress and report back to a server. So I need my script to avoid blocking while the program executes, but I also need to be able to read the output. Unfortunately, I don't think any of the methods available from Popen will read the output without blocking. I tried the following, which is a bit hack-y (are we allowed to read and write to the same file from two different objects?) import time import subprocess from subprocess import * with open("stdout.txt", "wb") as outf: with open("stderr.txt", "wb") as errf: command = ['Path\\To\\Program.exe', 'para', 'met', 'ers'] p = subprocess.Popen(command, stdout=outf, stderr=errf) isdone = False while not isdone : with open("stdout.txt", "rb") as readoutf: #this feels wrong for line in readoutf: print(line) print("waiting...\\r\\n") if(p.poll() != None) : done = True time.sleep(1) output = p.communicate()[0] print(output) Unfortunately, Popen doesn't seem to write to my file until after the command terminates. Does anyone know of a way to do this? I'm not dedicated to using python, but I do need to send POST requests to a server in the same script, so python seemed like an easier choice than, say, shell scripting. Thanks! Will

  • Removing a fields from a dynamic ModelForm

    - by Jérôme Pigeot
    In a ModelForm, i have to test user permissions to let them filling the right fields : It is defined like this: class TitleForm(ModelForm): def __init__(self, user, *args, **kwargs): super(TitleForm,self).__init__(*args, **kwargs) choices = [] # company if user.has_perm("myapp.perm_company"): self.fields['company'] = forms.ModelChoiceField(widget=forms.HiddenInput(), queryset=Company.objects.all(), required=False) choices.append('Company') # association if user.has_perm("myapp.perm_association") self.fields['association'] = forms.ModelChoiceField(widget=forms.HiddenInput(), queryset=Association.objects.all(), required=False) choices.append('Association') # choices self.fields['type_resource'] = forms.ChoiceField(choices = choices) class Meta: Model = Title This ModelForm does the work : i hide each field on the template and make them appearing thanks to javascript... The problem is this ModelForm is that each field defined in the model will be displayed on the template. I would like to remove them from the form if they are not needed: exemple : if the user has no right on the model Company, it won't be used it in the rendered form in the template. The problem of that is you have to put the list of fields in the Meta class of the form with fields or exclude attribute, but i don't know how to manage them dynamically. Any Idea?? Thanks by advance for any answer.

  • How to pass multiple parameter in DomainService - WCF

    - by S.Amani
    Hi, Let's say I have a window which should submit 3 model in client side (Silverlight Client Application). My problem is each time I submit the form, data on the server side which I passed them from client are empty. I've used nested class which contains my models, instead of passing multiple object as parameter, but it didn't work again. My Personnel Data Transfer Object Code is something like this : [DataContract] public class PersonnelDTO : EntityObject { [Key] [DataMember] public int PersonnelId { get; set; } [Include] [DataMember] [Association("Personnel_ID", "PersonnelId", "Personnel_ID")] public Personnel Personnel { get; set; } [Include] [DataMember] [Association("Personnel_Info_ID", "PersonnelId", "Personnel_Info_ID")] public Personnel_Info PersonnelInfo { get; set; } } I fill up this model to pass data from client to server (DomainService). and also my domain service code is : [Invoke] public void AddPersonnel(PersonnelDTO personnelDTO) { // Model are EMPTY in DTO ObjectContext.AddToPersonnels(personnelDTO.Personnel); ObjectContext.AddToPersonnel_Info(personnelDTO.PersonnelInfo); ObjectContext.SaveChanges(); } I don't know if there is a way to pass multiple parameter in WCF Service method include Generic List. Any advice will be graceful. Thanks.

  • Reloading a JTree during runtime

    - by Patrick Kiernan
    I create a JTree and model for it out in a class separate to the GUI class. The data for the JTree is extracted from a file. Now in the GUI class the user can add files from the file system to an AWT list. After the user clicks on a file in the list I want the JTree to update. The variable name for the JTree is schemaTree. I have the following code for the when an item in the list is selected: private void schemaListItemStateChanged(java.awt.event.ItemEvent evt) { int selection = schemaList.getSelectedIndex(); File selectedFile = schemas.get(selection); long fileSize = selectedFile.length(); fileInfoLabel.setText("Size: " + fileSize + " bytes"); schemaParser = new XSDParser(selectedFile.getAbsolutePath()); TreeModel model = schemaParser.generateTreeModel(); schemaTree.setModel(model); } I've updated the code to correspond to the accepted answer. The JTree now updates correctly based on which file I select in the list.

  • Positioning / Scrolling problem with Flex popup.

    - by user284163
    Hi all, I'm trying to work out a specific problem I'm having with positioning in Flex using the PopUpManager. Basically I'm wanting to create a popup which will scroll with the parent container - this is necessary because the parent container is large and if the user's browser window isn't large enough (this will be the case the majority of the time) - they will have to use the scrollbar of the container to scroll down. The problem is that the popup is positioned relative to another component, and it needs to stay by that component. <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"> <mx:Script> <![CDATA[ import mx.core.UITextField; import mx.containers.TitleWindow; import mx.managers.PopUpManager; private function clickeroo(event:MouseEvent):void { var popup:TitleWindow = new TitleWindow(); popup.width = 250; popup.height = 300; popup.title = "Example"; var tf:UITextField = new UITextField(); tf.wordWrap = true; tf.width = popup.width - 30; tf.text = "This window stays put and doesn't scroll when the hbox is scrolled (even with using the hbox as parent in the addPopUp method), I need the popup to be local to the HBox."; popup.addChild(tf); PopUpManager.addPopUp(popup, hbox, false); PopUpManager.centerPopUp(popup); } ]]> </mx:Script> <mx:HBox width="100%" height="2000" id="hbox"> <mx:Button label="Click Me" click="clickeroo(event)"/> </mx:HBox> </mx:Application> Could anyone give me any pointers in the right direction? Thanks.

  • Can a WPF ComboBox display alternative text when its selection is null?

    - by Garth T Kidd
    G'day! I want my WPF ComboBox to display some alternative text when its data-bound selection is null. The view model has the expected properties: public ThingoSelectionViewModel : INotifyPropertyChanged { public ThingoSelectionViewModel(IProvideThingos) { this.Thingos = IProvideThingos.GetThingos(); } public ObservableCollection<Thingo> Thingos { get; set; } public Thingo SelectedThingo { get { return this.selectedThingo; } set { // set this.selectedThingo and raise the property change notification } // ... } The view has XAML binding to the view model in the expected way: <ComboBox x:Name="ComboboxDrive" SelectedItem="{Binding Path=SelectedThingo}" IsEditable="false" HorizontalAlignment="Left" MinWidth="100" IsReadOnly="false" Style="{StaticResource ComboboxStyle}" Grid.Column="1" Grid.Row="1" Margin="5" SelectedIndex="0"> <ComboBox.ItemsSource> <CompositeCollection> <ComboBoxItem IsEnabled="False">Select a thingo</ComboBoxItem> <CollectionContainer Collection="{Binding Source={StaticResource Thingos}}" /> </CompositeCollection> </ComboBox.ItemsSource> </ComboBox> The ComboBoxItem wedged into the top is a way to get an extra item at the top. It's pure chrome: the view model stays pure and simple. There's just one problem: the users want "Select a thingo" displayed whenever the ComboBox' selection is null. The users do not want a thingo selected by default. They want to see a message telling them to select a thingo. I'd like to avoid having to pollute the viewmodel with a ThingoWrapper class with a ToString method returning "Select a thingo" if its .ActualThingo property is null, wrapping each Thingo as I populate Thingos, and figuring out some way to prevent the user from selecting the nulled Thingo. Is there a way to display "Select a thingo" within the ComboBox' boundaries using pure XAML, or pure XAML and a few lines of code in the view's code-behind class?

I copied it out of a working script. set pathToTemp to (POSIX path of ((path to desktop) as string)) -- change jpg to pict tell application "Image Events" try launch set albumArt to open file (pathToTemp & "albumart.jpg") save albumArt as PICT in file (pathToTemp & "albumart.pict") --the first 512 bytes are the PICT header, so it reads from byte 513 --this is to allow the image to be added to an iTunes track later. set albumArt to (read file (pathToTemp & "albumart.pict") from 513 as picture) close end try end tell The code is taking a jpg image, converting it to a PICT file, and then reading the file minus the header (the first 512 bytes). Later in the script, albumArt will be added to an iTunes track. I tried translating the code (minus the comments), but ASTranslate froze for a good 2 minutes before giving me this: Untranslated event 'earsffdr' #import "IEGlue/IEGlue.h" IEApplication *imageEvents = [IEApplication applicationWithName: @"Image Events"]; IELaunchCommand *cmd = [[imageEvents launch] ignoreReply]; id result = [cmd send]; #import "IEGlue/IEGlue.h" IEApplication *imageEvents = [IEApplication applicationWithName: @"Image Events"]; IEReference *ref = [[imageEvents files] byName: @"/Users/Doom/Desktop/albumart.jpg"]; id result = [[ref open] send]; #import "IEGlue/IEGlue.h" IEApplication *imageEvents = [IEApplication applicationWithName: @"Image Events"]; IEReference *ref = [[imageEvents images] byName: @"albumart.jpg"]; IESaveCommand *cmd = [[[ref save] in: [[imageEvents files] byName: @"/Users/Doom/Desktop/albumart.pict"]] as: [IEConstant PICT]]; id result = [cmd send]; 'crdwrread' Traceback (most recent call last): File "objcrenderer.pyc", line 283, in renderCommand KeyError: 'crdwrread' 'cascrgdut' Traceback (most recent call last): File "objcrenderer.pyc", line 283, in renderCommand KeyError: 'cascrgdut' 'crdwrread' Traceback (most recent call last): File "objcrenderer.pyc", line 283, in renderCommand KeyError: 'crdwrread' Untranslated event 'rdwrread' OK I have no clue how to make sense of this. Thanks for any and all help!

  • Using the groupby method in Python, example included

    - by randombits
    Trying to work with groupby so that I can group together files that were created on the same day. When I say same day in this case, I mean the dd part in mm/dd/yyyy. So if a file was created on March 1 and April 1, they should be grouped together because the "1" matches. Here's the code I have so far: #!/usr/bin/python import os import datetime from itertools import groupby def created_ymd(fn): ts = os.stat(fn).st_ctime dt = datetime.date.fromtimestamp(ts) return dt.year, dt.month, dt.day def get_files(): files = [] for f in os.listdir(os.getcwd()): if not os.path.isfile(f): continue y,m,d = created_ymd(f) files.append((f, d)) return files files = get_files() for key, group in groupby(files, lambda x: x[1]): for file in group: print "file: %s, date: %s" % (file[0], key) print " " The problem is, I get lots of files that get grouped together based on the day. But then I'll see multiple groups with the same day. Meaning I might have 4 files grouped that were created on the 17th. Later on I'll see another unique set of 2 files that are also created on the 17th. Where am I going wrong?

  • Core Data + Core Animation/CALayer together??

    - by ivanTheTerrible
    I am making an Cocoa app with custom interfaces. So far I have implemented one version of the app using CALayer doing the rendering, which has been great given the hierarchical structure of CALayers, and its [hitTest:] function for handling mouse events. In this early version, the model of the app are my custom classes. However, as the program grows I feel the urge of using Core Data for the model, not just for the ease of binding/undo management, but also want to try out the new technology. My method so far: In Core Data: creating a Block entity, with attributes xPos, yPos, width, height...etc. Then, creating a BlockView : CALayer class for drawing, which uses methods such as self.position.x = [self valueForKey:@"xPos"] to fetch the values from the model. In this case, every BlockView object has to also keep a local copy of xPos, which is NOT good. Do any of you guys have better suggestions? Edit: This app is a information visualization tool. So the positions, dimensions of the blocks are important, and should be persisted for later analysis.

  • Learning AES: the KeyBytes

    - by Tom Brito
    I got the following example from here: import java.security.Security; import javax.crypto.Cipher; import javax.crypto.spec.SecretKeySpec; public class MainClass { public static void main(String[] args) throws Exception { Security.addProvider(new org.bouncycastle.jce.provider.BouncyCastleProvider()); byte[] input = "www.java2s.com".getBytes(); byte[] keyBytes = new byte[] { 0x00, 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x0a, 0x0b, 0x0c, 0x0d, 0x0e, 0x0f, 0x10, 0x11, 0x12, 0x13, 0x14, 0x15, 0x16, 0x17 }; SecretKeySpec key = new SecretKeySpec(keyBytes, "AES"); Cipher cipher = Cipher.getInstance("AES/ECB/PKCS7Padding", "BC"); System.out.println(new String(input)); // encryption pass cipher.init(Cipher.ENCRYPT_MODE, key); byte[] cipherText = new byte[cipher.getOutputSize(input.length)]; int ctLength = cipher.update(input, 0, input.length, cipherText, 0); ctLength += cipher.doFinal(cipherText, ctLength); System.out.println(new String(cipherText)); System.out.println(ctLength); // decryption pass cipher.init(Cipher.DECRYPT_MODE, key); byte[] plainText = new byte[cipher.getOutputSize(ctLength)]; int ptLength = cipher.update(cipherText, 0, ctLength, plainText, 0); ptLength += cipher.doFinal(plainText, ptLength); System.out.println(new String(plainText)); System.out.println(ptLength); } } I imagine that the byte[] keyBytes should be random generated, so I gone to test the max size before do it. When adding one more byte 0x18 to the array, the exception raised: InvalidKeyException: Key length not 128/192/256 bits. But the original 18 bytes (from 0 to 17) are not multiple of nither 128, 192 or 256. I would like to understand the math here.. can anyone explain me? Thanks!

  • Magento - Authorize.net - Get Payment Update for expired transactions

    - by pspahn
    Magento 1.6.1 I have set up Authorize.net (AIM) for the client's store. Previously they were using saved CC method and entering information manually in Authorize.net's merchant terminal. Most of it is working as expected, however for transactions that are flagged as 'Suspected Fraud' by Authorize.net, if the client does not update the transaction manually before the authorization expires, using 'Get Payment Update' in Magento fails because the transaction is expired (I believe it's five days for an authorize only transaction). For the client, it seems the only way to update this order in Magento is to simply delete the order, as it doesn't appear the Paygate model knows about expired transactions. Performing 'Get Payment Update' simply returns 'There is no update for this payment'. I have already modified the file: /app/code/core/Mage/Paygate/Model/Authorize.net to have the correct API URL as described in issue #27117 ( http://www.magentocommerce.com/bug-tracking/issue?issue=12991 - must be logged in to view ). This resolved the button not working for all other orders; however this does not fix the issue I am describing. Is anyone familiar with Authorize.net's AIM API so that we can update these orders in Magento to something that makes sense (canceled, etc.) without having to delete the order? I am thinking it should be a case of adding a new order status to Magento, checking the update for an 'Expired' status, and setting the order to the newly created order status. -- edit -- I just ran a diff for the file mentioned above and noticed that Magento 1.7.0.2 includes the _isTransactionExpired() method which seems like it would be the fix. Can it be as simple as updating this model with the newer version?
