Browser-based (HTTP) file uploading is a great way to transfer arbitrary files from a client machine to the Web server which adds another dimension to Web-based applications. However, to enable this feature the client form should be submitted using "multipart/form-data" encoding.
Unfortunately, the ASP Request.Form object cannot be used with this encoding type (currently). For this reason, many solutions have been provided by third party components to solve this problem. However, most of thes... |

All client-side template engines enable you to create HTML (feel free to go ‘duh’). What they don’t all allow is the creation of event handlers and components over the markup they generate. The general approach with those engines is to do a second pass of code over the markup to create handlers and components. This is quite unfortunate as this generally requires some knowledge of the markup (which plays against separation of concerns) or something like the introduction of marker CSS classes into... |

Several people have asked questions like "is COM+ dead", "how does COM+ relate to .NET", etc. The answer is that COM+ is definitely not gone. It remains and will continue to be an important part of the overall programming model, and it can be fully leveraged from ASP.NET and the overall .NET Framework. You can continue to create COM+ components using VS6 and other compilers and then call them from ASP.NET pages. You can also take advantage of COM+ services with new classes built using the .NET F... |

This article presents a component that is used to add a sort indicator image to GridView columns.
The Internet provides a lot of sites that show how you can add some sort of sort indicator to a GridView, but all of them do this for a single GridView. Our application has quite a lot of GridViews that need this feature, and therefore I decided that a component would be the right way to go. A component has the advantage that I can code the behaviour just once and not for every single GridVie... |

Every now and then we are faced with a question concerning our web applications which is, "What kind of permissions the a user has on a certain file or folder?". The answer to this question assists in determining what kind of actions a user can or can?t perform on that object. For example in your web site you want certain users to be able to read the contents of a file but don?t allow them to make any modifications to it. So if you know beforehand that the logged in user does not have write perm... |

This application uses ATL, MFC, ASP and Crypt API. It will demonstrate how to make an ATL project that provides 2 cryptographic functions, how to use this component in your ASP projects, and how to register the component in MTS. The article also contains a GUI client console for directly testing the cryptographic functions.
This component can be used in Visual Basic, Access or Microsoft SQL.... |

In this part we will explain the remaining two components needed to build web spider, plus the relation between these components in our web spider application. The web browser component provides your application with Microsoft Internet Explorer capabilities such as document navigation, document viewing, and data downloading. Adding this component to your application is such as adding a complete web browser to your program. By which you can navigate to any URL from your ordinary desktop applicati... |

We live in a world of constant motion. Ideas, aided by the Internet revolution, rapidly transform from concept to reality and drive the wheels of progress forward. Stand still for too long and you’re outdated, dull, and losing to a new competitor that is riding the “2.0” wave. Nowhere is this reality clearer than in web development, where the oft hyped “Web 2.0” has become the mythical measuring stick by which all websites are deemed hot or not. If your website isn’t deemed “Web 2.0,” it’s alrea... |

XML has quickly become the new data structure standard for everything from database access to cross-platform computing. XML is typically considered to be a vehicle for data exchange, dynamic data presentation, and data storage. However, the potential of XML far surpasses those limited applications. This article examines one new use: the gathering of data across a number of forms in an ASP .NET Beta 1 framework application. The sample program is a Web app used for ordering pizza. It uses ASP and ... |

I have read that the .NET framework has great features to localize your application. I had to use them recently to create an English, Dutch, French and German "version" of one of my applications. I found out they worked well but it was very time consuming to set all the text properties of all controls for each language. Even worse you have to translate common terms like: OK, Cancel, New, Open, Close, etc. on every form if you want to use the designer. You can, of course, write code to fetch them... |

Some business clients still maintain their legacy COM business components while developing newer ones in .NET. Iterating a recordset involves complex while loops with MoveFirst/MoveNext methods and checking for BOF/EOF. The article will demonstrate how to create an encapsulating class that will let developers iterate a recordset using the for-each statement hiding the underlying recordset complexities.... |

In my previous article I showed how data-shaped (hierarchical) recordsets could be converted into an XML document using a recursive component. However, there are a few problems that need to be addressed before moving on to displaying the data in a browser. These hurdles include:
* The data has no state, so each recordset row needs to have its own node
* Repeating data
* Special characters need to be taken into consideration... |

Components are useful for extending the functionality of ASP, and running certain processes much faster than can be expected from the ASP interpreter. They are also fairly easily developed, and when you develop one in a language such as Visual Basic or Visual C++, the component will automatically be registered on the computer it was developed on at compile time. However, in some circumstances, you do not develop on your production server, and need to manually register the component on another se... |
