The first session after the keynotes was about HTML5 Web Sockets which has a Microsoft first draft implementation on HTML5 Labs. The concept of “Real Time Web” is very crucial and hard to implement (using push or polling messages to and from the client). In order to address the problem of client server communication (Bidirectional, Single TCP socket, In & Out of the browser and more) the HTML5 Web Sockets specification was created. The Specifications contain two specification groups: IETF WebSoc... |

The following article describes how you can create a proxy page that converts a SQL Server Report into a PDF file. When the code is executed, it will make a call to a report on a SQL Reporting Services Server, generate a PDF file and then present it to the user as an option download.
A nice benefit to this process is that you never have to save a physical file on the server and then direct the client to that file. Everything is done in memory, so there will be no file permission problems ... |

So you have built a cool web site with code you wrote or downloaded from great sites like CodeProject, the next thing you might want to do is testing it: Can your code handle more than, say 10 concurrent users? Does it have a memory leak that will eventually lead to crash if you don't reboot?... |

This is an unofficial Code Project application that can analyze forums over a range of posts to retrieve posting statistics for individual members. Like my other Code Project applications (and that of others like John and Luc), this app uses HTML scraping and parsing to extract the required information. So any change to the site layout/CSS can potentially break the functioning of this application. There's no workaround for that until the time that Code Project provides an official web-service th... |

This control is a simple modification to the "Color Picker" control By James White, which in turn is based off Chris Maunder's original Office 97 style Colour Picker.
The new code is a modification to the custom dialog box, which is infact a standard CColour dialog box. Here I have used a dialog based property sheet to choose standard and custom colours. I was hoping to capture the appearance of the color button that appears in some Windows dialogs, including the Display Properties|Appear... |

Visual Basic is certainly not my cuppa tea, but the Visual Basic IDE does have some good ideas which applications can benefit from. One these is the Color Chooser popup window which allows the user to select a desired color. I've extended the control to include the Web Colors which are found on the new Visual Studio .NET IDE.... |

This control is a simple modification to the "Office 97 style Colour Picker" control by Chris Maunder. You may refer to that article for futher details. The new code is dependant on the CColourPopup class from that article (though it is included in the source and demo downloads) with one small modification to its code that asserted the parent class was a CColourPicker.... |

Saying that a view-model belongs to the Application layer, and the Application layer doesn't references upper layers, and must not create or use visual objects, how can I open a Window, Dialog or any kind of Message Box on-the-fly, based on some logic triggered by the view or view-model?
Well, there are several options doing that, one is using kind of service which encapsulates that, providing an interface, so the view-model don't really work directly with the upper layer or WPF.... |

I need a color picker for a vector drawing program I am developing. After trying several color picker examples from CodeGuru and CodeProject, I found what I really need is a general 'well' control. It can not only serve as the base class of color picker, but also others. Also, I want this well control can be used as button in a dialog or from view, as well as a popup window. I also think it is good to use bitmap resource to draw each well if owner draw is not necessary.... |

There are lots of articles, which describe how to convert XML documents to the documents of other types using the XSL Formatting Objects. Most of them describe how to obtain HTML from XML and only few tell about PDF documents.
Such articles usually demonstrate simple examples (how to build the table or perform the text output). But sometimes we need to create representative reports or documents. In this case, developers face nontrivial problems – for example creating the table of contents... |

There are already several articles here on CodeProject describing different types of color pickers, and here is yet another example.
I needed a color picker for a project I was working on, and I wanted something different from the standard ColorDialog. After looking at a couple of different color pickers, I decided to go ahead and implement my own version which would meet these few requirements:
Color table with some predefined colors
Color picker (eye dropper) which let... |
