  • php SimpleCassie Cassandra TimeUUID

    - by chnet
    I created a column family Users using following command: create column family Users with comparator=TimeUUIDType and default_validation_class=UTF8Type; Then I insert a column into Users. It shows as follows. RowKey: jsmith =>(column=66829930-515b-11e0-8443-0f82b246fa40, value=hello, timestamp=1300451382) I want to access it using SimpleCassie. The command is: $data = $cassie->keyspace('Keyspace1')->cf('Users')->key('jsmith')->column('66829930-515b-11e0-8443-0f82b246fa40')->value(); (I also tried: $data = $cassie->keyspace('Keyspace1')->cf('Users')->key('jsmith')->column($cassie->uuid('66829930-515b-11e0-8443-0f82b246fa40')->__toString())->value();) However, They do not work. It always return NULL. How can I get the column value (hello) I want?

  • Django shows too many warnings when deleting an object

    - by valya
    Hello! I have two models: class Account(models.Model): main_request = models.ForeignKey('JournalistRequest', related_name='main_request') key = models.CharField(_('Key'), max_length=100) class JournalistRequest(models.Model): account = models.ForeignKey(Account, blank=True, null=True) When I try to delete a JournalistRequest, It shows warning with a lot of nesting, like Are you sure you want to delete the selected ?????? ??? objects? All of the following objects and their related items will be deleted: Journalist Request: some request Account: some account Journalist Request: some request Account: some account Journalist Request: some request Account: some account Journalist Request: some request Account: some account Journalist Request: some request All accounts are the same one (ids are same), and all requests are the same one, so I think it becaues of a recursion. But I have no idea how to solve this problem in Django 1.1.1! Can you help me?

  • Cast an NSDictionary value while applying an NSPredicate?

    - by RickiG
    Hi I have an Array of NSDictionary objects. These Dictionaries are parsed from a JSON file. All value objects in the NSDictionary are of type NSString, one key is called "distanceInMeters". I had planned on filtering these arrays using an NSPredicate, so I started out like this: NSPredicate *predicate = [NSPredicate predicateWithFormat:@"(distanceInMeters <= %f)", newValue]; NSArray *newArray = [oldArray filteredArrayUsingPredicate:predicate]; I believe this would have worked if the value for the "distanceInMeters" key was an NSNumber, but because I have it from a JSON file everything is NSStrings. The above gives this error:* -[NSCFNumber length]: unrecognized selector sent to instance 0x3936f00** Which makes sense as I had just tried to treat an NSString as an NSNumber. Is there a way to cast the values from the dictionary while they are being filtered, or maybe a completely different way of getting around this? Hope someone can help me :)

  • Reverse-engineer a Javascript object?

    - by TruMan1
    I have a Javascript object that I want to pass in more parameters, but the documentation is non-existant. My only option seems to be to reverse engineer the Javascript object to see what parameters and values I can pass in. For example, I want to see if there is a "zoom" parameter for the object and what values I can pass into the "mapType" parameter: <script type="text/javascript" src="http://maps.google.com/maps?oe=utf-8&amp;file=api&amp;v=2&amp;key=your-gmap-key"></script> <script type="text/javascript" src="https://share.findmespot.com/spot-widget/js/SpotMain.js"></script> <script type="text/javascript"> var widget = new Spot.Ui.LiveWidget({ renderTo: "spot-live-widget", feeds: [ "0Wl3diTJcqqvncI6NNsoqJV5ygrFtQfBB" ], height: 400, width: 500, mapType: "physical" }); </script> <div id="spot-live-widget"/> Any ideas on how to do that?

  • How to map hash keys to methods for an encapsulated Ruby class (tableless model)?

    - by user502052
    I am using Ruby on Rails 3 and I am tryng to map a hash (key, value pairs) to an encapsulated Ruby class (tableless model) making the hash key as a class method that returns the value. In the model file I have class Users::Account #< ActiveRecord::Base def initialize(attributes = {}) @id = attributes[:id] @firstname = attributes[:firstname] @lastname = attributes[:lastname] end end def self.to_model(account) JSON.parse(account) end My hash is hash = {\"id\":2,\"firstname\":\"Name_test\",\"lastname\":\"Surname_test\"} I can make account = Users::Account.to_model(hash) that returns (debugging) --- id: 2 firstname: Name_test lastname: Surname_test That works, but if I do account.id I get this error NoMethodError in Users/accountsController#new undefined method `id' for #<Hash:0x00000104cda410> I think because <Hash:0x00000104cda410> is an hash (!) and not the class itself. Also I think that doing account = Users::Account.to_model(hash) is not the right approach. What is wrong? How can I "map" those hash keys to class methods?

  • Can I have Visual Studio IDE auto-comple brackets?

    - by Alex K
    Suppose I have a line of code that starts like the following: Func1(Func2(Func3 Is it possible to set up Visual Studio (2005, 2008, 2010) IDE, so that when I hit ';' it will auto-complete all the brackets. I am only interested in brackets, nothing fancier. It doesn't have to be ';' key, it can be another key that auto-completes both brackets and ';'. This is a tiny thing that pops-up time and time again, and I've always wondered if I had to live with it. Thanks.

  • Java input method for Virtual Keyboad

    - by shekhar
    Hi, I am facing problem in implementing Input method for Virtual Keyboard, currently I am using robot class for sending input to any application from virtual keyboard. but for that I need to create mapping of key-code and unicode, which is not consistent on different keyboard layout, can I directly pass the UNICODE to any application using Input method without worry about mapping between keycode and unicode. any useful link or sample code will be useful. It is simple Java program which is always on top of any application and work as onscreen keyboard. using a mouse while you press any button (key) of the keyboard, the corresponding character will be typed in the application running below. This is working perfectly for English Alphabets. I am facing problem while I am doing for unicode.

  • How to return variable datatypes from a method

    - by Praesagus
    I have a method whose callers require different datatypes. I could repeat the requisite conversions a dozen times by putting them in each of the callers, but it seems much more efficient to do it once in the called method. public String myMethod(String myArg) { return DoSomething(myArg); } public Int32 myMethod(String myArg) { return Convert.ToInt32(DoSomething(myArg)); } private String DoSomething(key) { return SomeList[key]; } If I have multiple methods that pull data from SomeList and have to utilize different data types then in each I have to do a type conversion. Examples might be session variables or query or form requests or any other number of things. In VB I could say Function myMethod(myArg as String) as Variant myMethod=DoSomething(myArg) End Function Sorry if the original post was not very clear. I hope this makes more sense. Thanks

  • Securely Storing Optional Entropy While Using DPAPI

    - by Changeling
    So I am trying to store the symmetric key using DPAPI. All is well and great, but what to do with the entropy? This answered question here really doesn't provide enough insight. It seems like a slippery slope - I could use the machine store to store the entropy but then what prevents someone from getting at that as well? Note: I am storing the current key using the User Scope. So my question is - what is the best way to store the entropy using DPAPI?

  • WCF XmlSerializer assembly not speeding up first request

    - by Matt Dearing
    I am generating proxy classes to a clients java webservice wsdls and xsd files with svcutil. The first call made to each service proxy class takes a very long time. I was hoping to speed this up by generating the XmlSerializers assembly myself (based on the article How to: Improve the Startup Time of WCF Client Applications using the XmlSerializer), but when I do the first call to each service still takes the same amount of time. Here are the steps I am following: //generate strong name key file sn -k Blah.snk //generate the proxy class file svcutil blah.wsdl blah2.wsdl blah3.wsdl ... base.xsd blah.xsd ... /UseSerializerForFaults /ser:XmlSerializer /n:*,SomeNamespace /out:Blah.cs //compile the class into an assembly signing it with the strong name key file csc /target:library /keyfile:Blah.snk /out:Blah.dll Blah.cs //generate the XmlSerializer code this will give us Blah.XmlSerializers.dll.cs svcutil /t:xmlSerializer Blah.dll //compile the xmlserializer code into its own dll using the same key to sign it and referencing the original dll csc /target:library /keyfile:Blah.snk /out:Blah.XmlSerializers.dll Blah.XmlSerializers.dll.cs /r:Blah.dll I then create a standard Console application that references both Blah.dll and Blah.XmlSerializers.dll. I will then try something like: //BlahProxy is one of the generated service proxy classes BlahProxy p = new BlahProxy(); //this call takes 30ish seconds p.SomeMethod(); BlahProxy p2 = new BlahProxy(); //this call takes < 1 second p2.SomeMethod(); //BlahProx2y is one of the generated service proxy classes BlahProxy2 p3 = new BlahProxy2(); //this call takes 30ish seconds p3.SomeMethod(); BlahProxy2 p4 = new BlahProxy2(); //this call takes < 1 second p4.SomeMethod(); I know that the problem is not server side because I don't see the request made in Fiddler until around 29 seconds. Subsequent calls to each service take < 1 second, so thats why I was hoping the main slow down was the .net runtime generating the xmlserializer code itself, compiling it and loading the assembly. I figured this would be the reason the first call to each service is slow and the rest are fast. Unfortunatley, me generating the code myself is not speeding anything up. Does anyone see what I am doing wrong?

  • Determine the 'Overtype' mode using Javascript

    - by Snorkpete
    We are creating a web app to replace an old-school green-screen application. In the green-screen app, as the user presses the Insert key to switch between overtype and insert modes, the cursor changes to indicate which input mode the user is currently in. In IE (which is the official browser of the company), overtype mode also works, but there's no visual indication as to whether overtype mode is on or not, until the user starts typing and possibly over-writes existing information unexpectedly. I'd like to put some sort of visual indicator on the screen if in overtype mode. How can you determine if the browser is in 'overtype mode' from Javascript? Is there some property or function i can query to determine if the browser is in overtype mode? Even an IE-specific solution would be helpful, since our corporate policy dictates the browser to use as IE7 (pure torture, btw). (I do know that one solution is to do check for key presses of the Insert key. However, it's a solution that I'd prefer to avoid since that method seems a bit flaky & error-prone because I can't guarantee what mode the user would be in BEFORE he/she hits my page. ) The reasoning behind this question: The functionality of this portion of the green-screen app is such that the user can select from a list of 'preformatted bodies of text'. crude eg. The excess for this policy is: $xxxxxx and max limit is:$xxxxxx Date of policy is: xx/xx/xxxx and expires : xx/xx/xxxx Some other irrelevant text After selecting this 'preformatted text', the user would then use overtype to replace the x's with actual values, without disturbing the alignment of the rest of the text. (To be clear, they can still edit any part of the 'preformatted text' if they so wished. It's just that usually, they just wish to replace specific portions of the text. Keeping the alignment is important since these sections of text can end up on printed documents.) Of course, the same effect can be achieved by just selecting the x's to replace first, but it would be helpful (with respect to easing the transition to the web app) to allow old methods of doing things to continue to work, while still allowing 'web methods' to be used by the more tech-savvy users. Essentially, we're trying to make the initial transition from the green-screen app to the web app be as seemless as possible to minimise the resistance from the long-time green-screeners.

Usually I synchronize FROM database TO database project (using the Visual Studio data scheme compare new schema comparison). The synchronization works, BUT when I for example corrected the spelling of a key in the database and synchronized it - the file with the WRONG spelling of a key remains (albeit is commented out inside). the new one is correctly added. This file happens to be in: [project name]/Scheme Objects/Schemas/dbo/Tables/Keys But for sure there are others elsewhere. how to automatically remove such obsolete files when synchronizing? thnx

  • SQL Server Upgrade 'Developer > Enterprise'

    - by JD
    Hey guys, My company purchased Visual Studio Pro 2008 last year, which had a 'free' copy of SQL Server Developer, which I have been using for development. We are wanting to upgrade the copy of developer edition to enterprise (As we now want to use the server as a production server), and have purchased the licenses for this. Now... Morally we're in the clear... However does this comply with MS licensing T&C's? We have Developer installed how we want it, and don't really want to uninstall SQL Server Dev just to install SQL Server Ent. Is there a way to transfer the license key to our Enterprise key without having to reinstall? Thanks, JD

The form source: <form name="aspnetForm" method="post" action="list.aspx" language="javascript" onkeypress="javascript:return WebForm_FireDefaultButton(event, '_ctl0_ContentPlaceHolder1_cmdSearch')" id="aspnetForm"> <input type="hidden" name="__EVENTTARGET" id="__EVENTTARGET" value="" /> <input type="hidden" name="__EVENTARGUMENT" id="__EVENTARGUMENT" value="" /> <input type="hidden" name="__LASTFOCUS" id="__LASTFOCUS" value="" /> <input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="/..." /> <script type="text/javascript"> <!-- var theForm = document.forms['aspnetForm']; if (!theForm) { theForm = document.aspnetForm; } function __doPostBack(eventTarget, eventArgument) { if (!theForm.onsubmit || (theForm.onsubmit() != false)) { theForm.__EVENTTARGET.value = eventTarget; theForm.__EVENTARGUMENT.value = eventArgument; theForm.submit(); } } // --> </script> <script language="javascript"> <!-- var _linkpostbackhit = 0; function _linkedClicked(id, key, str, a, b) { if (!b || !_linkpostbackhit) { if (!a) { __doPostBack(key, id); _linkpostbackhit = 1; } else { if (window.confirm(str)) { __doPostBack(key, id); _linkpostbackhit = 1; } } } return void(0); } // --> </script> ... <a href="JavaScript:_linkedClicked('123456','_ctl0:ContentPlaceHolder1:Link', '',0,1);">123456</a> ... </form> I tried to add the 2 variables: page.forms.first['__EVENTTARGET'] = '_ctl0:ContentPlaceHolder1:Link' page.forms.first['__EVENTARUGMENT'] = '123456' and submit the form: page.forms.first.click_button(page.forms.first.buttons.first) The result returned only (re)show the current list of links as if I have not clicked on any of the links. Any help will be appreciated. Thanks!

  • Account preferences crashes on ListPreference

    - by Sionide21
    I have created an account type using the AccountAuthenticator stuff as done in the SampleSyncAdapter tutorial. I am now trying to get account preferences working. I have added the line android:accountPreferences="@xml/account_preferences" to my account-authenticator and account_preferences.xml looks like so: <?xml version="1.0" encoding="utf-8"?> <PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android"> <PreferenceCategory android:title="@string/alum_settings_title"/> <CheckBoxPreference android:key="sync_alum" android:title="@string/sync_alum" android:summaryOn="@string/sync_alum_check" android:summaryOff="@string/sync_alum_nocheck"/> <ListPreference android:key="sync_alum_since" android:title="@string/alum_years" android:entries="@array/years" android:entryValues="@array/years" android:dependency="sync_alum"/> </PreferenceScreen> The checkbox preference works exactly like it should but the ListPreference crashes the entire system with the following message: 05-14 22:32:16.794: ERROR/AndroidRuntime(63): android.view.WindowManager$BadTokenException: Unable to add window -- token null is not for an application I get the same error with EditTextPreference and with the custom subclass of DialogPreference I created.

  • How can I put my own text hover into default Eclipse editor?

    - by vitivy
    I need to put some extra information into to the standard "javadoc" hover, that shows up when you go with mouse over some token. Or I need to create a new hover showing that information while pressing some key (like alt) and then hovering (I can see that this is done e.g. with the shift key, which enables us to see the hover with sourcecode, instead of javadoc). So far I found documentation on how to create hover in your own editors, but I need to extend the default java editor. Basically I am interested in showing some e-mail information related to the classname (token) over which user is hovering. Is there any extension point that could be used for this? Thanks for any help!

  • App engine datastore - query on Enum fields.

    - by Gopi
    I am using GAE(Java) with JDO for persistence. I have an entity with a Enum field which is marked as @Persistent and gets saved correctly into the datastore (As observed from the Datastore viewer in Development Console). But when I query these entities putting a filter based on the Enum value, it is always returning me all the entities whatever value I specify for the enum field. I know GAE java supports enums being persisted just like basic datatypes. But does it also allow retrieving/querying based on them? Google search could not point me to any such example code. Details: I have printed the Query just before being executed. So in two cases the query looks like - SELECT FROM com.xxx.yyy.User WHERE role == super ORDER BY key desc RANGE 0,50 SELECT FROM com.xxx.yyy.User WHERE role == admin ORDER BY key desc RANGE 0,50 Both above queries return me all the User entities from datastore in spite of datastore viewer showing some Users are of type 'admin' and some are of type 'super'.

  • .NET: will Random.Random operate differently inside a static method

    - by Craig Johnston
    I am having difficulty with the following code which is inside a static method of a non-static class. int iRand; int rand; rand = new Random((int)DateTime.Now.Ticks); iRand = rand.Next(50000); The iRand number, along with some other values, are being inserted into a new row of an Access MDB table via OLEDB. The iRand number is being inserted into a field that is part of the primary key, and the insert attempt is throwing the following exception even though the iRand number is supposed to be random: System.Data.OleDb.OleDbException: The changes you requested to the table were not successful because they would create duplicate values in the index, primary key, or relationship. Change the data in the field or fields that contain duplicate data, remove the index, or redefine the index to permit duplicate entries and try again. Could the fact the method is static be making the iRand number stay the same, for some reason?

  • How to fix weird scrolling/alignment behavior when using keyboard in MenuStrip?

    - by bentsai
    I started noticing strange behavior when navigating the main toolbar of my Winforms application, and I don't know how to fix it. When I initially open the dropdown of the File menu, it looks like this: I begin to scroll down each item with the arrow keys, and everything is fine until I reach "Exit". As soon as I hit the down arrow key from "Log Off", or if I hit the up arrow key from "Open", the menu rearranges itself to look like this: I'm puzzled by this behavior. The menu still works, and from this point, if I start scrolling up, I can get the arrangement back to normal: A few observations: The menu still works. This doesn't happen when using the mouse. I have some code that toggles the Visible property of some of the menu items. I was able to modify what the arrangement was by playing around with this, but it was still messed up. Can anyone help me understand what is going on, and how to fix it?
