I recently had created a windows forms application in VB.Net2008 and made use of the BindingSource control to bind all the forms controls to the underlying SQL Queried data. I built user functionality on the form to allow the user to further filter (client side filtering ) the original data without having to re-query the database....

So far, we have seen that we can draw various images on graphics surfaces by using DrawImage. We have also seen how to implement rotate, flip, fit-height, fit-width, and zoom features. An imaging application may need to provide even more features, including scaling, skewing and high-performance rendering. Using GDI+ we can do all of this very easily. We will discuss some of these issues in this article....

XSL Transformations (XSLT) is known for making hard things easy and easy things hard. It can simplify complex transformation logic that would be extremely tedious to implement otherwise. But at the same time, XSLT's functional programming model can sometimes make it extremely difficult to perform trivial business logic. Often extending XSLT with traditional languages like VBScript, JScript®, or any Microsoft® .NET-supported language can offer the best of both worlds (for an introduction to XSLT ...

One of the advantages of the .NET architecture is that assemblies built with it contain lots of useful information that can be recovered using ILDASM, the intermediate language disassembler. A side effect, though, is that someone with access to your binaries can recover a good approximation of the original source code. Here the authors present program obfuscation as a way to deter reverse engineering. In addition, they discuss the different types of obfuscation technologies available and demonst...

MIME stands for "Multipurpose Internet Mail Extensions." It is a standard way of classifying file types on the Internet. By specifying a MIME type, application can easily identify the type of file and can extract more information and attributes about a file. Here are some useful links to Web resources that provides information about MIME types:...

When Windows 7 was announced, some year a go, I was expecting a total revamp of the menu system which Microsoft introduced with Windows 95. But for my disappointment, it hasn't changed anything drastically. But multi-touch enabled OS was my idea (I've seen people saying so many weird things as their idea in the Win 7 TV ads, so I wanted to call this as mine.) On the other hand, I was inspired by the iPhone’s UI which is really designed in a finger friendly manner and I though I should implement ...

The Save method of the Image class can be used to save images in different formats. This is what our code is used to save an images as a TIFF file:

curImage.Save(fileName, ImageFormat.Tiff);

In fact, the Save method does much more than just save an image in different formats. An overloaded Save method can take an argument of type EncoderParameters, which represents an encoder. An encoder is responsible for converting a file from one format to another and a decoder rever...

Metafiles contain information about how an image was created - including lists of graphics operations - rather than storing the image in pixel format. Graphics operations in a metafile are stored as records, which can be controlled (recorded and played back) individually....

The top picture above is the updated app. The colors are different and the gauges are different too. Instead of circle style guages, they are horizontal bars. A splashscreen was also added (pic above). There is also a Cursors Folder, and a USZIPS.txt file (in the zip file) that needs to be put in your Documents folder....

A serial foot pedal is a device which has three mechanical switches for play, rewind, and fast forward. People like medical transcriptionists use these devices for playing audio while they keep their hands busy on the keyboard. Any programmer who is developing solutions for such a firm should be able to find a software interface to incorporate the foot pedal device into the application....

You can write applications that are able to perform multiple tasks simultaneously. This ability, called multithreading, or free threading, is a powerful way to design components that are processor-intensive and require user input. An example of a component that might make use of multithreading would be a component that calculates payroll information. The component could process data entered into a database by a user on one thread while processor-intensive payroll calculations were performed on a...
