  • ASP.NET MVC2 - Resolve Parameter Attribute in Model Binder

    - by Nathan Taylor
    Given an action like: public ActionResult DoStuff([CustomAttribute("foo")]string value) { // ... } Is there any way to resolve the instance of value's CustomAttribute within a ModelBinder? I was looking at the MVC sources and chances are I'm just doing it wrong, but when I tried to replicate their code which retrieves the BindAttribute for a complex model, calling GetAttributes() did not return the attribute I am looking for. DefaultModelBinder GetTypeDescriptor(controllerContext, bindingContext).GetAttributes();

  • Implementing EAV pattern with Hibernate for User -> Settings relationship

    - by Trevor
    I'm trying to setup a simple EAV pattern in my web app using Java/Spring MVC and Hibernate. I can't seem to figure out the magic behind the hibernate XML setup for this scenario. My database table "SETUP" has three columns: user_id (FK) setup_item setup_value The database composite key is made up of user_id | setup_item Here's the Setup.java class: public class Setup implements CommonFormElements, Serializable { private Map data = new HashMap(); private String saveAction; private Integer speciesNamingList; private User user; Logger log = LoggerFactory.getLogger(Setup.class); public String getSaveAction() { return saveAction; } public void setSaveAction(String action) { this.saveAction = action; } public User getUser() { return user; } public void setUser(User user) { this.user = user; } public Integer getSpeciesNamingList() { return speciesNamingList; } public void setSpeciesNamingList(Integer speciesNamingList) { this.speciesNamingList = speciesNamingList; } public Map getData() { return data; } public void setData(Map data) { this.data = data; } } My problem with the Hibernate setup, is that I can't seem to figure out how to map out the fact that a foreign key and the key of a map will construct the composite key of the table... this is due to a lack of experience using Hibernate. Here's my initial attempt at getting this to work: <composite-id> <key-many-to-one foreign-key="id" name="user" column="user_id" class="Business.User"> <meta attribute="use-in-equals">true</meta> </key-many-to-one> </composite-id> <map lazy="false" name="data" table="setup"> <key column="user_id" property-ref="user"/> <composite-map-key class="Command.Setup"> <key-property name="data" column="setup_item" type="string"/> </composite-map-key> <element column="setup_value" not-null="true" type="string"/> </map> Any insight into how to properly map this common scenario would be most appreciated!

  • WIX Installing an EXE after Msi install finishes.

    - by Chris
    Hi, I have created an MSI package which when finishes runs an exe. <Package InstallerVersion="200" Compressed="yes" /> <Media Id="1" Cabinet="media1.cab" EmbedCab="yes" /> <Directory Id="TARGETDIR" Name="SourceDir"> <Directory Id="ProgramFilesFolder"> <Directory Id="INSTALLLOCATION" Name="Installer Example"> <Component Id="VSTOR30.EXE" Guid="4fb0aee7-ec5b-4179-8938-a2be4df8ca0e"> <File Id="VSTOR30.EXE" Source="C:\Projects\InstallationTarget\ExampleInstaller\VSTOR30.EXE" KeyPath="yes" Checksum="yes" /> </Component> </Directory> </Directory> </Directory> <Feature Id="ProductFeature" Title="Installation Target" Level="1"> <ComponentRef Id="VSTOR30.EXE" /> </Feature> <InstallExecuteSequence> <Custom Action="RunEXE" After="InstallFinalize">NOT Installed</Custom> </InstallExecuteSequence> <CustomAction Id="RunEXE" FileKey="VSTOR30.EXE" ExeCommand="[#VSTOR30.EXE]" Execute="immediate" Return="asyncNoWait"> </CustomAction> <UI /> The MSI installs but the EXE is not run. I am calling it after Install Finalize and checking the install sequence in ORCA shows that it is being called at the correct time. I need deploy this through group policy software installation which uses a silent install without inputs. If i use a custom UI and run the EXE in the exit dialog <UI> <UIRef Id="WixUI_Minimal" /> <Publish Dialog="ExitDialog" Control="Finish" Event="DoAction" Value="LaunchApplication">WIXUI_EXITDIALOGOPTIONALCHECKBOX = 1 and NOT Installed</Publish> </UI> <Property Id="WIXUI_EXITDIALOGOPTIONALCHECKBOXTEXT" Value="RunEXE" /> <!-- Step 3: Include the custom action --> <Property Id="WixShellExecTarget" Value="[#VSTOR30.exe]" /> <CustomAction Id="RunEXE" BinaryKey="WixCA" DllEntry="WixShellExec" Impersonate="yes" /> Then i can install the software after the msi has finished running, however when putting this group policy the EXE doesn't install. Is there anything i am missing? Chris

  • iphone - double tap fail safe way

    - by mike
    I am trying to detect double taps on a view, but when the double tap comes, the first tap triggers an action on TouchesBegan, so, before detecting a double tap a single tap is always detected first. How can I make this in a way that just detects the double tap? I cannot use OS 3.x gestures, because I have to make it compatible with old OS versions. thanks

  • How is parsing phase in a compiler different from a rule engine ?

    - by abhinav
    Hi, I have a rough understanding of how the compilers work (I mean languages, grammars, lexical analysis, parsing etc). The rule engines have various rules and associated action, just like you have rules in the grammars and you can associate actions with them in parser-generator tools like ANTLR. So I am a bit confused on how to differentiate between these two. Could anyone give a clearer, more formal explanation for the differences ? Thanks, Abhinav.

  • Help with OpenSSL request using Python

    - by Ldn
    Hi i'm creating a program that has to make a request and then obtain some info. For doing that the website had done some API that i will use. There is an how-to about these API but every example is made using PHP. But my app is done using Python so i need to convert the code. here is the how-to: The request string is sealed with OpenSSL. The steps for sealing are as follows: • Random 128-bit key is created. • Random key is used to RSA-RC4 symettrically encrypt the request string. • Random key is encrypted with the public key using OpenSSL RSA asymmetrical encryption. • The encrypted request and encrypted key are each base64 encoded and placed in the appropriate fields. In PHP a full request to our API can be accomplished like so: <?php // initial request. $request = array('object' => 'Link', 'action' => 'get', 'args' => array( 'app_id' => 303612602 ) ); // encode the request in JSON $request = json_encode($request); // when you receive your profile, you will be given a public key to seal your request in. $key_pem = "-----BEGIN PUBLIC KEY----- MFwwDQYJKoZIhvcNAQEBBQADSwAwSAJBALdu5C6d2sA1Lu71NNGBEbLD6DjwhFQO VLdFAJf2rOH63rG/L78lrQjwMLZOeHEHqjaiUwCr8NVTcVrebu6ylIECAwEAAQ== -----END PUBLIC KEY-----"; // load the public key $pkey = openssl_pkey_get_public($key_pem); // seal! $newrequest and $enc_keys are passed by reference. openssl_seal($request, $enc_request, $enc_keys, array($pkey)); // then wrap the request $wrapper = array( 'profile' => 'ProfileName', 'format' => 'RSA_RC4_Sealed', 'enc_key' => base64_encode($enc_keys[0]), 'request' => base64_encode($enc_request) ); // json encode the wrapper. urlencode it as well. $wrapper = urlencode(json_encode($wrapper)); // we can send the request wrapper via the cURL extension $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, 'http://api.site.com/'); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_POSTFIELDS, "request=$wrapper"); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); $data = curl_exec($ch); curl_close($ch); ?> Of all of that, i was able to convert "$request" and i'v also made the JSON encode. This is my code: import urllib import urllib2 import json url = 'http://api.site.com/' array = {'app_id' : "303612602"} values = { "object" : "Link", "action": "get", "args" : array } data = urllib.urlencode(values) json_data = json.dumps(data) What stop me is the sealing with OpenSSL and the publi key (that obviously i have) Using PHP OpenSSL it's so easy, but in Python i don't really know how to use it Please, help me!

  • Error inflating class android.widget.CompoundButton

    - by snctln
    [Disclaimer: This has been cross posted on the Android Developers Google Group I am trying to use a CompoundButton in a project I am working on. Every time I try and use it by declaring it in my layout xml file I receive the error "01-04 12:27:46.471: ERROR/AndroidRuntime(1771): Caused by: android.view.InflateException: Binary XML file line #605: Error inflating class android.widget.CompoundButton" After fighting the error for a half an hour I decided to try a minimalistic example. I am using the latest eclipse developer tools, and targeting android 2.2 makign the minimum sdk required 2.2 (8). Here is the activity java code: package com.example.CompoundButtonExample; import android.app.Activity; import android.os.Bundle; public class CompoundButtonExampleActivity extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); } } Here is the layout xml code: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/hello" /> <CompoundButton android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/hello" /> </LinearLayout> Here is the manifest xml code: <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.CompoundButtonExample" android:versionCode="1" android:versionName="1.0"> <application android:icon="@drawable/icon" android:label="@string/app_name"> <activity android:name=".CompoundButtonExampleActivity" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> <uses-sdk android:minSdkVersion="8" /> </manifest> As you can see it is just the default hello world project that eclipse creates for you when you start a new Android project. It only differs in the fact that I add a "CompoundButton" to the main layout in a vertical LinearLayout. Can anyone confirm this bug? Or tell me what I am doing wrong?

  • Android Market: Application not visible on some Devices

    - by Andreas
    Hello, i have written an application that needs to process outgoing calls. Everything works fine, the application has already a few hundred downloads, but now i get feedback from people who would like to download it, yet cannot find it. I have done some tests and have found that the permission "PROCESS_OUTGOING_CALLS" seems to be responsible for this. If i include it in an app, people with branded phones (at least in Germany) cannot find it, as soon as i remove this permission, everything is fine (when i re-insert it again, the app vanishes again) The weird thing is, that those users can see other apps which use this permission in the market. I have compared my manifest file to outputs from other manifest files and cannot understand why it doesn't work. Here is the manifest file for a test application i wrote to test the problem: <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.eventkontor.marketavailabilitytest" android:versionName="1.2" android:versionCode="3" android:installLocation="auto"> <application android:icon="@drawable/icon" android:label="@string/app_name"> <activity android:name=".showMain" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> <uses-sdk android:minSdkVersion="3" android:targetSdkVersion="4" /> <uses-permission android:name="android.permission.INTERNET"></uses-permission> <uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS"></uses-permission> <uses-permission android:name="android.permission.READ_CONTACTS"></uses-permission> <uses-permission android:name="android.permission.VIBRATE"></uses-permission> <uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission> <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"></uses-permission> <supports-screens android:normalScreens="true" android:resizeable="true" android:largeScreens="true" android:smallScreens="false"></supports-screens> </manifest> Does anyone have an idea what i'm doing wrong?

  • how to enable layout in XmlHttpReeuqest in symfony

    Symfony detects if it receives a XmlHttpRequest and automatically turns off your debug bar and layout. However I'd like to have the response decorated with a specified layout. Also I don't want to add custom line of code in the [FONT=Courier]action[/FONT] to enable the layout, I wish I can just make a configuration through yml files. Thanks in advance.
