• Cooking with Wessty: HTML 5 and Visual Studio

  - by David Wesst

  The hardest part about using a new technology, such as HTML 5, is getting to what features are available and the syntax. One way to learn how to use new technologies is to adapt your current development to help you use the technology in comfort of your own development environment. For .NET Web Developers, that environment is usually Visual Studio 2010. This technique intends on showing you how to get HTML 5 Intellisense working in your current version of Visual Studio 2008 or 2010, making it easier for you to start using HTML 5 features in your current .NET web development projects. Quick Note According to the Visual Web Developer team at Microsoft, the Visual Studio 2010 SP1 beta has support for both HTML 5 and CSS 3. If you are willing to try out the bleeding edge update from Microsoft, then you won’t need this technique. --- Ingredients Visual Studio 2008 or 2010 Your favourite HTML 5 compliant browser (e.g. Internet Explorer 9) Administrator privileges, or the ability to install Visual Studio Extensions in your development environment. Directions Download the HTML 5 Intellisense for Visual Studio 2008 and 2010 extension from the Visual Studio Extension Gallery. Install it. Open Visual Studio. Open up a web file, such as an HTML or ASPX file. he HTML Source Editing toolbar should have appeared. (Optional) If it did not appear, you can activate it through the main menu by selecting View, then Toolbars, and then select HTML Source Editing if it does not have a checkbox beside it. (NOTE: If there is a checkbox, then the toolbar is enabled) In the HTML Source Editing toolbar, open up the validation schema drop box, and select HTML 5. Et voila! You now have HTML 5 intellisense enabled to help you get started in adding HTML 5 awesomeness to your web sites and web applications. Optional – Setting HTML 5 Validation Options At this point, you may want to select how Visual Studio shows validation errors. You can do that in the Options Menu. To get to the Options Menu… In the main menu select Tools, then Options. In the Options window, select and expand Text Editor, then HTML, followed by selecting Validation.

• Linq to SQL Lazy Loading in ASP.Net applications

  - by nikolaosk

  In this post I would like to talk about LINQ to SQL and its native lazy loading functionality. I will show you how you can change this behavior. We will create a simple ASP.Net application to demonstrate this. I have seen a lot of people struggling with performance issues. That is mostly due to the lack of knowledge of how LINQ internally works.Imagine that we have two tables Products and Suppliers (Northwind database). There is one to many relationship between those tables-entities. One supplier...(read more)

• I can't program because old coding style. This is normal to programmers?

  - by Renato Dinhani Conceição

  I'm in my first real job as programmer, but I can't solve any problems because of the coding style used. The code here: don't have comments don't have functions (50, 100, 200, 300 or more lines executed in sequence) uses a lot of if statements with a lot of paths has variables that make no sense (eg.: cf_cfop, CF_Natop, lnom, r_procod) uses a language I am unfamiliar with (Visual FoxPro 8 from 2002) I feel like I have gone back to 1970. Is it normal for a programmer familiar with OOP, clean-code, design patterns, etc. to have trouble with coding in this old-fashion way?

• How to profile LINQ to Entities queries in your asp.net applications - part 1

  - by nikolaosk

  I have been teaching ASP.Net and EF in one of my classes and I have been asked on the various ways we can profile database activity. Everyone that I know that uses EF as its data access layer has the same question. "How can I see the T-SQL code that the LINQ to Entities engine generates on the fly?" I know a lot of people use VS studio built-in visualisers but that is not enough. A lot of developers use SQL Server Profiler. That is also a good solution since we can see the queries(generated from...(read more)

• Updating a Progress Bar within the Status Bar [migrated]

  - by Muhnamana

  I'm trying to figure out how to incorporate a progress bar within the status bar to show how much processing is completed. Below is my example of updating the progress bar (not sure if this is the correct way or not) Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick ToolStripProgressBar1.Value = ToolStripProgressBar1.Value + 2 If ToolStripProgressBar1.Value = 100 Then ToolStripProgressBar1.Value = 0 ToolStripProgressBar1.Value = ToolStripProgressBar1.Value + 2 Timer1.Enabled = True End If End Sub Here is the code within the button. Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1Run.Click ToolStripStatusLabel1.Text = "Processing..." Timer1.Enabled = True 'more code to be inserted here End Sub What I'm not sure is how to update the progress bar based on the amount of code you have and once the processing is complete, update the ToolStripStatusLabel1 to show "Processing...Complete!".

• How to make Firefox windows style less space consuming?

  - by chocobai

  Firefox takes up so much space on small screens, so I'm searching for solutions that make firefox' interface less space consuming on ubuntu 12.04 with gnome3. Good examples are the chromium-style, but chromium is kind of slow in gnome3. Chromium does it, firefox on osx does it. Is this also possible on ubuntu via a custom modification or something? Here a screenshot of what I am thinking about: Firefox on OSX: https://wiki.mozilla.org/images/5/50/Firefox-4-Mockup-i06-%28OSX%29-%28TabsTop%29-%28Persona%29.png Thanks for your help.

• Connect Digest : 2011-03-12

  - by AaronBertrand

  Background Last year, I came to a very tough decision that I would cease publicizing Connect items in an attempt to drive up votes and get important issues fixed. This was almost entirely due to a couple of MVPs criticizing me for raising awareness of certain Connect items instead of letting them be found "naturally." I wasn't sure what world they were living in, where droves of everyday end users just happened to stumble upon Connect items without any prompting. I suppose it could be said that the...(read more)

• Switching from Debug into Release Mode with VS2010 as IDE and Intel C++ Compiler 13

  - by Drazick

  I have a code of a Plug In from an SDK. The code is in Debug Mode. I use Intel Compiler which only applies optimizations in Release Mode. Under configuration manager of the project only "Debug" mode is defined. How could I switch to "Release" mode and enable all Intel Compiler's optimizations? If I enable them on debug mode nothing is applied (Empty Report). I couldn't find the trick to do so. Thank You.

• Multiple style sheets best practice

  - by user1145927

  I currently am working on a project which has one large style sheet for about 20 pages. The style sheet contains some styles which are specific for certain pages. I'd like to break the style sheet up so there is one style sheet for each page with one master style sheet that handles everything generic. The reason I want to do this is so people can work on multiple pages without having to worry about who has that large style sheet checked out (I'm using TFS). Is this good practice?

• Fluent API Style Usage

  - by Chris Dwyer

  When programming against a fluent API, I've seen the style mostly like this: var obj = objectFactory.CreateObject() .SetObjectParameter(paramName, value) .SetObjectParameter(paramName, value) .DoSomeTransformation(); What is the reasoning behind putting the dot at the beginning of the line instead of the end of the line like this: var obj = objectFactory.CreateObject(). SetObjectParameter(paramName, value). SetObjectParameter(paramName, value). DoSomeTransformation(); Or, is it merely a style thing that a team makes a consensus on?

• WPF TreeView: How to style selected items with rounded corners like in Explorer

  - by Helge Klein

  The selected item in a WPF TreeView has a dark blue background with "sharp" corners. That looks a bit dated today: I would like to change the background to look like in Explorer of Windows 7 (with/without focus): What I tried so far does not remove the original dark blue background but paints a rounded border on top of it so that you see the dark blue color at the edges and at the left side - ugly. Interestingly, when my version does not have the focus, it looks pretty OK: I would like to refrain from redefining the control template as shown here or here. I want to set the minimum required properties to make the selected item look like in Explorer. Alternative: I would also be happy to have the focused selected item look like mine does now when it does not have the focus. When losing the focus, the color should change from blue to grey. Here is my code: <TreeView x:Name="TreeView" ItemsSource="{Binding TopLevelNodes}" VirtualizingStackPanel.IsVirtualizing="True" VirtualizingStackPanel.VirtualizationMode="Recycling"> <TreeView.ItemContainerStyle> <Style TargetType="{x:Type TreeViewItem}"> <Setter Property="IsExpanded" Value="{Binding IsExpanded, Mode=TwoWay}" /> <Setter Property="IsSelected" Value="{Binding IsSelected, Mode=TwoWay}" /> <Style.Triggers> <Trigger Property="IsSelected" Value="True"> <Setter Property="BorderBrush" Value="#FF7DA2CE" /> <Setter Property="Background" Value="#FFCCE2FC" /> </Trigger> </Style.Triggers> </Style> </TreeView.ItemContainerStyle> <TreeView.Resources> <HierarchicalDataTemplate DataType="{x:Type viewmodels:ObjectBaseViewModel}" ItemsSource="{Binding Children}"> <Border Name="ItemBorder" CornerRadius="2" Background="{Binding Background, RelativeSource={RelativeSource AncestorType=TreeViewItem}}" BorderBrush="{Binding BorderBrush, RelativeSource={RelativeSource AncestorType=TreeViewItem}}" BorderThickness="1"> <StackPanel Orientation="Horizontal" Margin="2"> <Image Name="icon" Source="/ExplorerTreeView/Images/folder.png"/> <TextBlock Text="{Binding Name}"/> </StackPanel> </Border> </HierarchicalDataTemplate> </TreeView.Resources> </TreeView>

• Change the style of WinForm border?

  - by Dodi300

  Is it possible to change the style of a WinForm border? I know that if the border is removed, it takes away the functionality to resize the program. Therefore is there a way to change the style of it? At the moment, I've removed the text from the border, set the "FormBorderStyle" to "SizableToolWindow" and set the "ControlBox" to false. That makes it look like this: But I want it to look something like this, but still be resizeable: (Maybe with a different color line)

• jQuery: Setting 'style' attribute of element with object

  - by JamesBrownIsDead

  I saw this in our codebase the other day: link.attr('style', map({ color: '#9a4d9e', cursor: 'default' })); map is defined as: function map(map) { var cssValue = []; for (var o in map) { cssValue.push(o + ':' + map[o] + ';') } return cssValue.join(';'); } Is map necessarily? Is there a shorter way to do this? It's important to note that the "style" attribute overrides any styles set by a class added/defined in the "class" attribute.

• How to perform "shell" icon embedding in Visual Studio 2010?

  - by JustABill

  As far as I can tell, there have been (at least?) three types of icon embedding. There's the original style used by shell32.dll and friends, .Net's embedding, and the new type that WPF uses. I'm looking for how to perform the first one, as I want to have a few other icons available as resources for a jumplist, which can only accept that style. However, I can't figure out how to embed in this style, only the other two. How do I do this? All the results I find on google, etc are for adding icons to ResX files or similar. I am using C#, if it matters.

• How do I add a WSDL to a Visual Studio 2005 project?

  - by Ben McCormack

  One of our vendors provides a web service API to allow their customers to validate data in a database. As part of their SDK, they provide a WSDL (Web Service Definition Language) file that, according to their documentation, can "be read by software applications and application development tools. An application tool such as Microsoft's Visual Studio can import a WSDL document and automatically generate software classes that access the Web Services the WSDL defines." I'm currently using Visual Studio 2005. What do I need to do to get Visual Studio to do the magic code generation for me?

• How do I view Visual Studio BuildLog.htm files without cutting and pasting into an external browser

  - by bgoodr

  This may or may not be specific to VS2005 (as that is the version I'm referring to for this question). I find often the case is that I see this in the Output panel inside Visual Studio 2>Build log was saved at "file://c:\\vsdll_example\MyExecRefsDll\Debug\BuildLog.htm" Now, since that looks and smells like a URL, I would have thought that I could simply left mouse click on it, or left mouse double-click on it, and a browser window of some sort would be displayed. No, that doesn't work. So, to view it, I have to cut and paste the "file://bla/bla/bla" part into an external window. Is there a way to set up Visual Studio to allow me to browse to that file directly, or view it inside Visual Studio IDE, or something to that effect, without the extra fiddling with cutting and pasting? Or is there some type of keybinding I'm not aware of? Thanks, bg
