I thought this would be simple... Trying to create a login does an ajax check before submit


I have the standard .net login control that is working.  (Still learning .net after 15yrs of classic)

What I want to do is OnButtonClick run a javascript function (to do an ajax call to the db to check if login is valid or not) and if it returns true, then submit the form normally, else don't submit. The piece that I can't figure out, is how to correctly override the default click even to hit my JS routine and then submit the form properly afterwards.

Thanks ahead of time

Windows Shell: Create Namespace Extensions for Windows Explorer with the .NET Framework


Extending the Windows shell with namespace extensions allows you to create some custom functionality for Windows Explorer. One common use is to enable Explorer to present a list of items that do not exist in one real folder, but actually reside in a number of places. The view on the folder makes it look like these items are in one place, so managing them becomes easier. This article illustrates the process of creating custom shell namespace extensions using C# and the .NET Framework. The author dispels some myths about the difficulty of writing such extensions, and shows that it is easier than it was before .NET. Along the way he outlines undocumented interfaces and describes advanced techniques for consuming them in .NET.

ASP.NET: Create Snazzy Web Charts and Graphics On the Fly with the .NET Framework


Knowledge workers can understand data more effectively when raw numbers are presented in a graphical format. This is especially true when displaying database information on a Web page, where a simple chart can make the difference between a dry presentation and a vivid data source. In the past, creating dynamic, data-based charts on the fly in ASP required purchasing a third-party, image-generating COM component. Now with ASP.NET, developers can access the .NET Framework's drawing classes directly with C# to create dynamic images and charts.

Windows Management Instrumentation: Create WMI Providers to Notify Applications of System Events


Windows Management Instrumentation (WMI) is based on an industry-wide standard for notifications used to manage objects and devices across a network. By receiving WMI events, an application can be notified of changes to data in WMI itself. This allows the developer to notify the consuming application that certain system configuration data has changed, without the application having to poll WMI continuously for this data. The author presents an explanation of the different types of events in WMI, then goes on to develop an event provider.

XML in .NET: .NET Framework XML Classes and C# Offer Simple, Scalable Data Manipulation


Microsoft .NET introduces a new suite of XML APIs built on industry standards such as DOM, XPath, XSD, and XSLT. The .NET Framework XML classes also include innovations that offer convenience, better performance, and a more familiar programming model, tightly coupled with the new .NET data access APIs-ADO.NET. XmlWriter, XmlReader, and XmlNavigator classes and classes that derive from them, including XMLTextReader and XMLTextWriter, encapsulate a number of functionalities that previously had to be accomplished manually. A discussion of the XMLDOM-Document is also included.
