  • Determine signals connected to a given slot in Qt

    - by Cody Brocious
    I've injected myself into a Qt application, and I'm attempting to figure out what signals a given slot is connected to, but can't find any information on doing this. Is there a mechanism for doing this out of the box? If so, is this exposed to QtScript? (If not, I can wrap it easily enough.) If there is no such mechanism, what would be the best way to add it? I cannot manipulate the existing application outside of simple hooking, but I could hook QObject::connect and store the connections myself, just not sure if that's the best way to go about it.

  • ASP.net VB Timers

    - by Tom Gullen
    I would like to be able to time a page load time in ASP.net (VBscript). Adding Trace="true" to the page directive is nice, but I need to actually time an event and store it in a variable. In ASP it was easy with the Timer object, but in .net I can't find anything on Google. I need something along the lines of: Dim startTime Dim endTime startTime = now() doBigFunction() endTime = now() response.write("That took " & endTime - startTime & " milliseconds") Cheers!

  • Filtering A MySQL Result Set Based On The Return Value Of A Function

    - by Joshua
    I'm a SQL noob, and I need a little bit of help understanding the big picture of if it is possible, and if so how to go about filtering a result set based on the return value of a function which is passed one of the fields of the record. Let's say I have a table called "Numbers" with just one field: "Value". How could I correctly specify the following "pseudo-sql"?: SELECT Value FROM numbers WHERE IsPrime(Value)=true Can I accomplish such a thing, and if so, where/how do I put/store "IsPrime"? I'm using MySQL.

  • In Google App Engine, what is the simplest way to keep a record of items that you have put into memc

    - by Chris Boesch
    I am starting to use memcache more frequently to avoid having to recalculate things between page requests. When the memcache periodically clears, as it is designed to do, I have to start all over rebuilding various items that I have placed in memcache. What I would like to do is create a very simple model that enables me to periodically save the items that I put into memcache based on the memcache keys that I'm using along with a datetime that is related to the data being memcached. What is the best way to do this? I'm looking for something like this: class MemcacheRecord(db.Model): key = db.StringProperty(required=True) value = #Something that can store whatever memcache can validThru = db.DateTimeProperty(required=True) def set(self, key, value, validThru): #Save a new memcache record newMemcacheRecord = MemcacheRecord(key=key, value=value, validThru=validThru) .. return True # or False def get_latest(self, key): #Get the memcache record with the most recent validThru datetime latestMemcacheRecord = MemcacheRecord.all().order('-validThru').get() return {'validThru':latestMemcacheRecord.validThru, 'value':latestMemcachRecord.value}

  • Setting a "dependency property" in code

    - by Matt B
    I'm on a roll today... I have the following code delaring a dependency property inside a class called ActionScreen: #region Dependency Properties & Methods public string DescriptionHeader { get { return (string)GetValue(DescriptionHeaderProperty); } set { SetValue(DescriptionHeaderProperty, value); } } // Using a DependencyProperty as the backing store for DescriptionHeader. This enables animation, styling, binding, etc... public static readonly DependencyProperty DescriptionHeaderProperty = DependencyProperty.Register("DescriptionHeader", typeof(string), typeof(ActionScreen), new UIPropertyMetadata("xxx")); #endregion I bind to this property in my Xaml as so: <GridViewColumn DisplayMemberBinding="{Binding Description}" Header="{Binding DescriptionHeader}" Width="350" /> Now I want to be able to set the parameter from my code behind when I recieve an event - but it's not working: public string DescColText { set { this.Dispatcher.Invoke(DispatcherPriority.Normal, new Action(delegate() { DescriptionHeader = value; })); } }

  • mysql: encrypting and decrypting data

    - by cbrulak
    Does mysql provide a mechanism for storing and retrieving encrypted data? I don't mean passwords, I mean real strings. I'd like to encrypt a string, store in mysql and then retrieve the decrypted string at a later date. So, I know there is the AES_Encrypt and decrypt functions. But they ask for a key. (which is fine) but I wondering if you call those functions and use your user password as the key. Or something else that is super-simple. Also, is there a simple wrapper for the AES_Encrypt & decrypt functions in Rails? Or do you need to build the query manually?

  • arbitrary typed data in django model

    - by Dmitry Shevchenko
    I have a model, say, Item. I want to store arbitrary amount of attributes on it, like title, description, release_date. And i want them to be not just strings but have python type, so string, boolean, datetime etc. What are my options here? EAV pattern with separate name-value table won't work because of the same DB type across all values. JSONField can probably help, but it doesn't know about datetime, for example. Also i was looking at PickeField, it fits perfectly, but i'm a bit concerned about performance.

  • Backing Up Transaction Logs to Tape?

    - by David Stein
    I'm about to put my database in Full Recovery Model and start taking transaction log backups. I am taking a full nightly backup to another server and later in the evening this file and many others are backed up to tape. My question is this. I will take hourly (or more if necessary) t-log backups and store them on the other server as well. However, if my full backups are passing DBCC and integrity checks, do I need to put my T-Logs on tape? If someone wants point in time recovery to yesterday at 2pm, I would need the previous full backup and the transaction logs. However, other than that case, if I know my full back ups are good, is there value in keeping the previous day's transaction log backups?

  • how to convert string to double with proper cultureinfo

    - by Vinay Pandey
    Hi All, I have two nvarchar fields in database to store the DataType and DefaultValue, I have a DataType Double and value as 65.89875 in english format. Now I want the user to see the value as per the selected browser language format (65.89875 in English should be displayed as 65,89875 in german). Now if the user edits from german format to 65,89875 which is 65.89875 equivalent in english, and the other user views from english browser it comes as 6589875. This happens because in DB it was stored as 65,89875 and when converted using english culture it becomes 6589875 since it considers , as seperator. Any Idea how I get this working for all the browsers?

  • ASP.NET MVC AuthorizeAttribute passing values to ActionMethod?

    - by subskii
    Hi everyone I'm only a newcomer to ASP.NET MVC and am not sure how to achieve a certain task the "right way". Essentially, I store the logged in userId in HttpContext.User.Identity and have written an EnhancedAuthorizeAttribute to perform some custom authorization. In the overriden OnAuthorization method, my domain model hits the database to ensure the current user id can access the passed in routeValue "BatchCode". The prototype is: ReviewGroup GetReviewGroupFromBatchCode(string batchCode); It will return null if the user can't access the ReviewGroup and the OnAuthorization then denies access. Now, I know the decorated action method will only get executed if OnAuthorization passes, but I don't want to hit the database a second time to get the ReviewGroup again. I am thinking of storing the ReviewGroup in HttpContext.Items["reviewGroup"] and accessing this from the controller at the moment. Is this a feasible solution, or am I on the wrong path? Thanks!

  • Windows Workflow Foundation: Multiple applications

    - by Petr Felzmann
    We are running several ASP.NET applications (one per customer) based on our custom framework (which just extend ASP.NET). Each web application use its own database (Initial Catalog in the term of connection string). Now we would like to add workflow capability to the applications (to our framework respectively). The particular workflows will be the same for all the applications only some initial settings of each workflow can vary, e.g. in one application the e-mail will be send to the user X, but in other application to the user Y. The question is if we can install one workflow engine (with one database for persistence) and share this for all workflows in all web applications. If so, how then workflow engine get knows the particular workflow belongs to which web application? Should we store some application identifier somewhere in workflow? Thanks for suggestions!

  • How do I replace colours in a movieclip?

    - by Oli
    I am trying to take a movieclip of a character and change the colour of their clothes. The character is comprised of vectors. So far I have semi-sucessfully used this method: stop the movieclip take the bitmap data from the current frame use threshold to replace the colour store the resulting bitmap data in an array add an onenterframe function - clear the current frame and add the bitmap data from the processed data in the array So - this works pretty well. Each frame is only processed once at the beginning and then the write to the movieclip is very quick. However! As the replacement is being performed on a bitmap there is an amount of aliasing that takes place to remove jaggies/pixelation. This produces colours that are not matched using threshold. So the main colour is replaced correctly but it is surrounded by a halo of mixed colours :( I am sure there should be a better way to do this. Any ideas or answers would be greatly apreciated - Thanks.

  • in-memory database in Python

    - by Claudiu
    I'm doing some queries in Python on a large database to get some stats out of the database. I want these stats to be in-memory so other programs can use them without going to a database. I was thinking of how to structure them, and after trying to set up some complicated nested dictionaries, I realized that a good representation would be an SQL table. I don't want to store the data back into the persistent database, though. Are there any in-memory implementations of an SQL database that supports querying the data with SQL syntax?

  • How can I efficiently group a large list of URLs by their host name in Perl?

    - by jesper
    I have text file that contains over one million URLs. I have to process this file in order to assign URLs to groups, based on host address: { 'http://www.ex1.com' = ['http://www.ex1.com/...', 'http://www.ex1.com/...', ...], 'http://www.ex2.com' = ['http://www.ex2.com/...', 'http://www.ex2.com/...', ...] } My current basic solution takes about 600 MB of RAM to do this (size of file is about 300 MB). Could you provide some more efficient ways? My current solution simply reads line by line, extracts host address by regex and puts the url into a hash. EDIT Here is my implementation (I've cut off irrelevant things): while($line = <STDIN>) { chomp($line); $line =~ /(http:\/\/.+?)(\/|$)/i; $host = "$1"; push @{$urls{$host}}, $line; } store \%urls, 'out.hash';

  • Help Reading Binary Image Data from SQL Server into PHP

    - by Joe Majewski
    I cannot seem to figure out a way to read binary data from SQL server into PHP. I am working on a project where I need to be able to store the image directly in the SQL table, not on the file system. Currently, I have been using a query like this one: INSERT INTO myTable(Document) SELECT * FROM OPENROWSET(BULK N'C:\image.jpg', SINGLE_BLOB) as BLAH This works fine to actually insert the image into the table, but I haven't yet figured a way to retrieve it and get my image back. I am doing this with PHP, and ultimately will have to make a stored procedure out of it, but can anyone enlighten me on a way to get that binary data (varbinary(MAX)) and generate an image on the fly. I expected it to be simple to use a SELECT statement and add a content-type to the headers that indicated it was an image, but it's simply not working. Instead, the page will just display the name of the file, which I have encountered in the past and understand it to be an error with the image data.

  • Stop browser from filling textboxes with details

    - by TenaciousImpy
    Hi, I've run into a really annoying problem, and I'm hoping it's just a setting I've missed. I've got an ASP.NET application which allows users to enter their username/password in various places (e.g. login, change password, change username etc..). When I logged in, the browser asked if I would like to store the user details. Usually, I click 'no', but this time I decided to click 'yes'. Now, certain textboxes in my form are prefilled with the username or password. Is it possible to remove these, as they sometimes appear in textboxes which shouldn't be prefilled. I tried setting AutoCompleteType=none and Text='' but it still gets prefilled. The textboxes don't have much in common, except the same CssClass and, for password boxes, TextMode=password. The names are different, although sometimes they include the word name (e.g. fullName, userName). Is there a way to stop the browser from filling certain textboxes? Thanks

  • Sencha Touch 2: List does not display in Panel

    - by jrboddie
    I am working on an MVC app in Sencha Touch 2 and am having trouble getting a list to display in a nested panel. The structure of the app has a main view which is a tab panel. One of the items in the tab panel is a defined panel, xtype: 'homepanel'. An item in this panel is the list, xtype: 'newslist' that is linked to the appropriate store and model files. The list does not display unless I change its parent 'homepanel' to a type, Ext.navigation.View. What am I missing in the definition of 'homepanel' as a Panel that prevents the display of the list? Ext.define('ACSO.view.Home', { extend: 'Ext.Panel', //<--works if Ext.navigation.View xtype: 'homepanel', requires: [ 'Ext.TitleBar', 'ACSO.view.NewsList' ], config: { title: 'Home', iconCls: 'home', cls: 'home', scrollable: true, styleHtmlContent: true, items: [ { xtype: 'newslist' } ] } });

    Hi Guys, We are a web design company going down the road of setting up a revision management system and all the processes around how we are going to use it etc. We mainly develop our websites on a Joomla and what i wanted to know is how other companies manage their repositories when dealing with a CMS.

But i dont have the entity to populate. Please tell me how to accomplish my needs.

  • best mysql field setup to have a "couples" member profile data saving.

    - by acctman
    Couple database profile entry, which would be the best way to save data. Also the data will be retrieved via php coding and if it could be down with one query code that would be ideal. Within the site_member table create multiple field for each field... ex: m_firstname1, m_firstname2, m_age1, m_age2, etc... Store the couple member data in one field each... and separate with a comma in the data field ex: m_firstname (Mike, Sherry) Create a separate table site_member_c duplicating the same fields that are in site_member table. This is roughly about 10 fields

  • Storing DOM reference elements in a Javascript array

    - by webzide
    Dear experts, I was trying to dynamically generate DOM elements using JS. I read from Douglas Crockford's book that DOM is very very poorly structured. Anyways, I would like to create a number of DIVISION elements and store the reference into an array so it could be accessed later. Here's the code for(i=0;i<3;i++){ var div=document.body.appendChild(document.createElement("div")); var arr=new Array(); arr.push(div); } Somehow this would not work..... There is only 1 div element created. When I use the arr.length to test the code there is only 1 element in the array. Is there another way to accomplish this? Thanks in advance

  • Rails: translations for table's column.

    - by Andrew
    In rails application I have two models: Food and Drink. Both food and drink have a name, which has to be stored in two languages. How do I better realize translations for theese tables? First solution I realized was to replace name column with name_en and name_ru. Another solution is to encode with YAML hash like { :en => 'eng', :ru => 'rus' } and store yaml as a name. What would you recommend, assuming content is not static? Maybe there's good article?
