Some time ago, I needed to have two picturebox controls on one form. One larger picturebox shows an image, while the other zooms a portion of the same image, depending on the position of the cursor. I could not find a ready-made solution or example source code for it, so I struggled a bit and got it to work properly, without flickering or lagging. I hope some of you can use this or find it helpful....

This idea came about when I was writing an application for a client, in which the client insisted that the images not be stored in the database, but in a web repository. Although I initially resisted the idea, but the more I thought about it, the more it grew on it. For one thing, it offered an alternative to image storage to the database (which is the standard), or to the local drive (which I despise). The other advantage is that it would work really well with a web application that uses the sa...

Some applications, be it desktop or web, require working with images. Aptly speaking, the good paradigm is banking applications. Withdrawal of an amount of money from a bank account requires signature verification of the account holder. Normally, specimen signatures of customers are archived as images in such applications. There can be a couple of ways to work around to store images. One is typically to tag each image with a unique identifier and save the image at a physical location accessi...

Often, the creative group and/or site builders on the project determine that the look and feel needed for a site cannot be handled by mere text and style sheets. This will normally lead to having a number of images that are just text or some text on top of a navigation button. When this occurs the developer could get frustrated with maintenance or site changes because a simple textual change forces the creative designer to get involved again so they can modify or create a new image. If the site ...
