• Adding a transparent bitmap to a windows button

  - by cmaughan

  It's a while since I've done this, but I'm trying to add a custom button graphic to a windows button, with some transparent areas. I've tried various schemes but can't seem to get the transparent areas to show. Here's my code: hbmpUpDisabled = LoadImage(instance,MAKEINTRESOURCE(IDB_UPARROWDISABLED), IMAGE_BITMAP, 0, 0, LR_DEFAULTSIZE | LR_LOADTRANSPARENT | LR_LOADMAP3DCOLORS ); SendMessage(GetDlgItem(hWndDlg, IDC_MOVEUP),BM_SETIMAGE,(WPARAM)IMAGE_BITMAP,(LPARAM)hbmpUpDisabled); Does anyone notice any problems here? It works if my bitmap is a 1-bit bitmap. I couldn't get a 32 bit bitmap to work, and I'm not sure how to setup a 24 bit or 8 bit bitmap to do it.... I tried a custom 255,0,255 color (which IIRC is a default transparent value), but so far no joy....

• Sandcastle not adding param documentation

  My method looks as follows ''' <summary> ''' Adds the activity.

• How do polymorphic inline caches work with mutable types?

  - by kingkilr

  A polymorphic inline cache works by caching the actual method by the type of the object, in order to avoid the expensive lookup procedures (usually a hashtable lookup). How does one handle the type comparison if the type objects are mutable (i.e. the method might be monkey patched into something different at run time). The one idea I've come up with would be a "class counter" that gets incremented each time a method is adjusted, however this seems like it would be exceptionally expensive in a heavily monkey patched environ since it would kill all the PICs for that class, even if the methods for them weren't altered. I'm sure there must be a good solution to this, as this issue is directly applicable to Javascript and AFAIK all 3 of the big JS VMs have PICs (wow acronym ahoy).

• My way of Comparing CPUs

  - by abbasi

  There are many types of CPUs, like Pentiume, Atom, core 2 duo, core iX (X = 3,5, ....), But I always don't look at them this way! I always look at their speed which in GHZ unit and then compare them with each other. For example when some CPU is in type of 'X' with 2 GHZ of speed and another one is in type of 'Y' with 2.2 GHZ of speed, I say the second one ('Y') has better speed and also better performance. Is it a correct way? Thanks

• Bulletin board - Database optimisation

  - by andrew

  This question is a follow on from this Question The project and problem The project I am currently working on is a bulletin board for a large non-profit organisation. The bulletin board will be used to allow inter-office communication within the organisation. I am building the application and have been having trouble extracting the results that I need from my database because I don't think it is properly normalized and because of limitations in my knowledge of relational database theory and mysql. I would appreciate input into the design of the board in general and in particular, ways that the database structure can be improved to facilitate efficient queries and help me develop this application and future application faster Business Logic The bulletin board will be used in the following way Posting bulletins and responses to bulletins Employees or 'users' in offices around the country will be able to post messages to the bulletin board.Bulletins must be posted to a location and categorised- i'll call these "bulletins". Users will be able to post any number of replies to any one bulletin and users will be able to reply to their own bulletin - i'll call these 'replies'. Rating bulletins and replies Users will be able to either 'like' or 'dislike' a bulletin or a reply and the total number of likes or dislikes will be shown for each bulletin or reply. Viewing the bulletin board and responses Bulletins can be displayed chronologically. Users can sort bulletins chronologically or chronologically by the latest reply to that bulletin(let me know if you need more explanation) When a particular bulletin is selected, replies to that bulletin will be displayed chronologically @PerformanceDBA - edited 10:34 est 28/12/10I have begun implementing the data model. I assume that the 6th data model is the physical model because it contains the associative tables. I am going to post any questions that I have below. I will put up a database dump once I am done. I will then put up a list of all the queries that I need to run on the database and begin writing them. I hope you had a good Christmas. I'm in Canada and there's snow!

• Obtaining reference to Class instance by string name - VB.NET

  - by Jeff Williams

  Is it possible using Reflection or some other method to obtain a reference to a specific class instance from the name of that class instance? For example the framework for the applications i develop heavily uses public class instances such as: Public bMyreference as MyReference = new MyReference Then throughout the application bMyReference is used by custom controls and code. One of the properties of the custom controls is the "FieldName" which references a Property in these class instances (bMyReference.MyField) as a string. What i would like to be able to do is analyze this string "bMyReference.MyField" and then refer back to the actual Instance/Property. In VB6 I would use an EVAL or something simular to convert the string to an actual object but this obviously doesn't work in VB.net What I'm picturing is something like this Dim FieldName as String = MyControl.FieldName ' sets FielName to bMyReference.MyField Dim FieldObject() as String = FieldName.Split(".") ' Split into the Object / Property Dim myInstance as Object = ......... ' Obtain a reference to the Instance and set as myInstance Dim myProperty = myInstance.GetType().GetProperty(FieldObject(1))

• Why would a TableAdapter populate a DataSet with "1/1/2000" for an entire timestamp column?

  - by Rob

  I have a TableAdapter filling a DataSet, and for some reason every select query populates my timestamp column with the value 1/1/2000 for every selected row. I first verified that original values are intact on the DB side; for the most part, they are, although it seems a few rows lost their original timestamp because of update queries performed programmatically before the issue was discovered. The DataColumn type is DateType, while the database (Postgres) column type is timestamp. Up until recently, this was all playing very nicely. I noticed the issue in a bound DataGridView control, and verified that this is not related to data binding by utilizing the 'Preview Data' option in the VS DataSet Editor. Usually when I notice unexpected values popping up in my application it's related to a mis-configured property, type conflict, or another silly mistake I've made. So after checking properties and types, and even recreating the TableAdapter from scratch, to say I'm a little baffled is an understatement. Does anyone have any ideas of what I could do to fix the issue and/or diagnose the cause?

• Running programs by typing some alias in Windows

  - by devoured elysium

  Is there an easy way in windows to set a given string, like "sidb" to run a program or open a given folder in Windows? My original idea was to be able to run commands like that in the "Execute" start button menu (or Win + R),so I'd just have to do WIN+R and type "sidb". What is the best way to accomplish this? EDIT: May I rephrase this as : Is there a way to define for example, in systems variables, sibd="C:.......blabla\ and then I'd just have to type "sibd" in Run?

• jquery - add to hidden input field on keypress?

  - by Simpson88Keys

  I've got a hidden input field that I want to append text to depending upon what a user enters in two other fields. So, <input type="hidden" name="name" value="" /> <input type="text" name="first" value="" /> <input type="text" name="second" value="" /> If the user types First in the first input field and Second in the second input field, I want the name input field to be "First Second"... Tried using keyup and keypress, but can't get it to append to what's already there?

• Is it possible to use an input within a <label> field?

  - by javanix

  I have a bunch of optional "write-in" values for a survey I'm working on. These are basically a radio button with a textbox within the answer field - the idea being that you would toggle the button and write something into the box. What I'd like to do is have the radio button toggled whenever a user clicks in the text field - this seems like a use-case that makes a lot of sense. Doing this: <input type="radio" id="radiobutton"><label for="radiobutton">Other: <input type="text" id="radiobutton_other"></label> works fine in Chrome (and I am guessing, other WebKit browsers as well), but there are weird selection issues in Firefox, so I'm assuming its a non-standard practice that I should stay away from. Is there a way to replicate this functionality without using JavaScript? I have an onclick function that will work, but we're trying to make our site usable for people who might have NoScript-type stuff running.

• Can't access font resource in Silverlight class library

  - by Matt

  I have a reasonably large Silveright 3.0 project on the go, and I'm having issues accessing a couple of custom font resources from within one of the assemblies. I've got a working test solution where I have added a custom font as a resource, and can access it fine from XAML using: <TextBlock Text="Test" FontFamily="FontName.ttf#Font Name" /> The test solution consists of the TestProject.Application and the TestProject.Application.Web projects, with all the fun and games obviously in the TestProject.Application project However, when I try this in my main solution, the fonts refuse to show in the correct type face (instead showing in the default font). There's no difference in the way the font has been added to project between the test solution and the main solution, and the XAML is identical. However, there is a solution layout difference. In the main solution, as well as having a MainApp.Application and MainApp.Application.Web project, I also have a MainApp.Application.ViewModel project and a MainApp.Application.Views project, and the problem piece of XAML is the in the MainApp.Application.Views project (not the .Application project like the test solution). I've tried putting the font into either the .Application or .Application.Views project, tried changing the Build Action to Content, Embedded Resource etc, all to no avail. So, is there an issue accessing font resources from a child assembly that I don't know about, or has anyone successfully done this? My long term need will be to have the valid custom fonts being stored as resources in a separate .Application.FontLibrary assembly that will be on-demand downloaded and cached, and the XAML controls in the .Application.Views project will need to reference this FontLibrary assembly to get the valid fonts. I've also tried xcreating this separate font library assembly, and I can't seem to get the fonts from the second assembly. As some additional information, I've also tried the following font referencing approaches: <TextBlock Text="Test" FontFamily="/FontName.ttf#Font Name" /> <TextBlock Text="Test" FontFamily="pack:application,,,/FontName.ttf#Font Name" /> <TextBlock Text="Test" FontFamily="pack:application,,,/MainApp.Application.Views;/FontName.ttf#Font Name" /> <TextBlock Text="Test" FontFamily="pack:application,,,/MainApp.Application.Views;component/FontName.ttf#Font Name" /> And a few similar variants with different assembly references/sub directories/random semi colons. And so far nothing works... anyone struck this (and preferably solved it)?

• Need to reload current_cart to get the test passed

  - by leomayleomay

  I'm testing my online store app with RSpec, here's what I'm doing: # spec/controllers/line_items_controller_spec.rb require 'spec_helper' describe LineItemsController do describe "POST 'create'" do before do @current_cart = Factory(:cart) controller.stub!(:current_cart).and_return(@current_cart) end it 'should merge two same line_items into one' do @product = Factory(:product, :name => "Tee") post 'create', {:product_id => @product.id} post 'create', {:product_id => @product.id} assert LineItem.count.should == 1 assert LineItem.first.quantity.should == 2 end end end # app/controllers/line_items_controller.rb class LineItemsController < ApplicationController def create current_cart.line_items.each do |line_item| if line_item.product_id == params[:product_id] line_item.quantity += 1 if line_item.save render :text => "success" else render :text => "failed" end return end end @line_item = current_cart.line_items.new(:product_id => params[:product_id]) if @line_item.save render :text => "success" else render :text => "failed" end end end The problem right now is it never added up two line_items having the same product into one, because the second time I entered into the line_items_controller#create, the current_cart.line_items is [], I have run current_cart.reload to get the test passed, any idea what's going wrong?

• Problem with layout of control when dynamically creating winform and controls for the Form

  - by Ashwani Roy

  I get this response from a web service call. Something like this <Response> <Control1 type = "DropdownList" value= "USA,UK,Sweden,UAE"/> <Control2 type = "Textbox" value= "Contries"/> <Control3 type = "Button" value= "None"> </Response> Based on this I de-serialize it into List<Controls>. Now I need to be able to dynamically create a winform based on these controls. My problem is the layout. I want to be able to create them nicely separated (If possible vertically aligned) in batches of lets say 5.So If I need 15 controls I have 3 columns and 5 rows. What would be best way to achieve this? I know that I can use the inbuilt positioning properties like top, width etc., but maybe someone out there has done something similar in a better way.

• advantages of Zend_Db_Table vs raw (My)SQL?

  - by sunwukung

  Currently working on a new Zend application and developing the Model. Having worked with Zend_Db_Table before, I opted to replace references in the Model to the Table API with a custom SQL script to take care of data access duties. Now I'm looking at developing a new application/domain model, and I wanted to get some feedback from people re: their experiences with Zend_Db API vs raw SQL, and use cases where it would be preferable to use the API. From a project perspective, the DB platform is unlikely to change from MySQL - so it doesn't need to be particularly abstract - and I assume writing a custom SQL API will be more performant than the assorted classes the Zend DB API requires.

• Haskell maps returning a monad

  - by sabauma

  The lookup function in Data.Map and Data.IntMap currently return values wrapped in Maybe with the type signature lookup :: Ord k => k -> Map k a -> Maybe a It used to have the more general type of lookup :: (Monad m, Ord k) => k -> Map k a -> m a I realize the former likely reduces the need of extra type specification, but the latter would make it much more general and allow lookup to be used in list comprehensions. Is there any way to mimic this behavior with the newer version, or would I have to use an older version of the library?

• Symfony2 & Twig - theming file upload widget

  - by Sacred Socks

  I have an Symfony2 edit form for an entity and one of the fields is for the user's profile picture. I'm trying to theme the Twig file upload widget so that the current picture set for the field is displayed above the file input. So far, I have: {% form_theme edit_form _self %} {% block field_widget %} {% set type = type|default('text') %} {% if type == 'file' %} <img src="{{ value }}" /> {% endif %} {{ block('form_widget_simple') }} {% endblock %} All works well except that the value variable is blank (which makes sense I guess). My question is how can I get hold of the path to the file? Is there a way to pick it out of the form values for the field? Could I perhaps pass it through as an option to the field? Srz if this is a dumb question, still pretty new to Symfony and Twig..

• How can you logically group HTML elements without taking the help of CSS classes ?

  - by Perpetualcoder

  I know that in jQuery you can use something like $(".cssClass") to get all elements with this class. However in plain html and javascript how do you group elements logically? For example: <input id="fee1" data-id="1" data-group="Fees" type="text" value="$15.00"/> <input id="fee2" data-id="2" data-group="Fees" type="text" value="$25.00"/> <input id="fee3" data-id="3" data-group="Fees" type="text" value="$35.00"/> I want to create a javascript function like this: function GetByDataGroup(dataGroup){ /* returns something like [[1,"$15.00"],[2,"$25.00"],[3,"$35.00"]]*/ } EDIT : Due to some political reasons I cant use jQuery or any framework..i know it doesnt make sense :)

• Apply a specific class to the first item in a series with PHP

  I have a php script that echoes a series of uploaded images and I need to apply a class to the first image echoed in the series. Is this possible? For example, if I want to display 10 images and apply a class to only the first image, how would I go about it? Here is the code, I am working with: <div id="gallery"> <?php query_posts('cat=7'); while(have_posts()) { the_post(); $image_tag = wp_get_post_image('return_html=true'); $resized_img = getphpthumburl($image_tag,'h=387&w=587&zc=1'); $url = get_permalink(); $Price ='Price'; $Location = 'Location'; $title = $post->post_title; echo "<a href='$url'><img src='$resized_img' width='587' height='387' "; echo "rel=\"<div class='gallery_title'><h2>"; echo $title; echo "</h2></div>"; echo "<div class='pre_box'>Rate:</div><div class='entry'>\$"; echo get_post_meta($post->ID, $Price, true); echo "</div><div class='pre_box'>Location:</div><div class='entry'>"; echo get_post_meta($post->ID, $Location, true); echo "</div>\""; echo "'/></a>"; echo ""; } ?> On line 13, the code looks like this: echo "<a href='$url'><img src='$resized_img' width='587' height='387' "; For the first item only, I need it to look like this: echo "<a href='$url' class='show'><img src='$resized_img' width='587' height='387' ";

• ruby on rails: audio/mp3 content header download

  - by bandhunt

  How do you set the headers for downloads in ruby/rails? In php I'd set the header for an mp3 download like this: header("Content-Transfer-Encoding: binary"); header("Content-type: audio/mp3"); header("Content-Disposition: attachment; filename=\"$songname.mp3\""); header("Content-Length: " . $size); @readfile("http://example.com/12345.mp3"); Seems like there should be an easy should an easy solution. I did find this: response.headers['Content-type'] = 'Content-type: audio/mp3' But I'm not sure how/where the readfile would come into play and other headers. Thanks!

When EntityFramework is asked to provide a new ObjectContext I receive a SerializationException saying that my Custom Business Principal type cannot be found. So far all tests that use EntityFramework fail when running through VS2012's test runner or Resharper7's test runner. I have tried NCrunch's test runner and they all pass. Thank you in advance.

• New wxpython controls not displaying until resize

  - by acrosman

  I have created a custom control (based on a panel) in wxPython that provides a list of custom controls on panel within it. The user needs to be able to add rows at will and have those rows displayed. I'm having trouble getting the new controls to actually appear after they are added. I know they are present, because they appear after a resize of the frame, or if I add them before Show() is called on the frame. I've convinced myself it's something basic, but I can't find the mistake. The add function looks like this: def addRow(self, id, reference, page, title, note): newRow = NoteListRow(self.listPanel, id, reference, page, title, note) self.listSizer.Add(newRow, flag=wx.EXPAND | wx.LEFT) self.rows.append(newRow) if len(self.rows) == 1: self.highliteRow(newRow) self.Refresh() self.Update() return newRow I assume I'm missing something about how refresh and update are supposed to behave, so even a good extended reference on those would likely be helpful.
