In a recent project I found the need to be able to drop an image from Internet Explorer onto my form and capture the URL of the image. If you have tried using any of the text formats to get the drop data then you know this does not work. At best you will get the locally cached path of the image file. There is little or no documentation on the subject, and attempting to search for information only yields others seeking the same answers. This is why I decided to make this an article.

This article examines how to design and create dynamic user interfaces using the Windows Presentation Foundation (WPF). Along the way we will explore a demo application which uses XAML for creating a dynamic user interface to display rich and interactive alert messages to the user.

This article is about getting controls found in Windows Vista to make use of the new Windows Vista user interface. Included in the project are some components (Commandlinks, ImageButton, SplitButton) that work just like the Windows Vista themed controls. The article would aim to achieve most of the interface effects (like the fade-in/out) effects seen throughout Windows Vista.

One of the coolest features to be introduced with Windows Vista is the new built in speech recognition facility. To be fair, it has been there in previous versions of Windows, but not in the useful form in which it is now available. Best of all, Microsoft provides a managed API with which developers can start digging into this rich technology. For a fuller explanation of the underlying technology, I highly recommend the Microsoft whitepaper. This tutorial will walk the user through building a common text pad application, which we will then trick out with a speech synthesizer and a speech recognizer using the .Net managed API wrapper for SAPI 5.3. By the end of this tutorial, you will have a working application that reads your text back to you, obeys your voice commands, and takes dictation.

In some cases you need to know what the best codepage (encoding) is to either transfer text over the internet or store it in a text file. One could argue that Unicode always does the trick but I needed the most efficient (byte saving) way to transfer data.

Detecting a code page from text is a very tricky task. But luckily, Microsoft provides the MLang API, in which the IMultiLang3 interface is used for outbound encoding detection.

Similarly, the IMultiLang2 interface has a function to detect the encoding of an incoming byte array. This is very handy for codepage detetion of text stored in files or for text that needs to be sent over the internet..
