Debugging

ASP.Net web forms, as the webpages are officially known, can become cumbersome to handle when they grow richer. The first line of defense, in such cases, is offered by the Browser Debugging Tools. Read on to find out more about such tools and how they help.

In this new installment, you'll discover how to write an even more robust version of a debugger visualizer using WIndows Presentation Foundation (WPF). You'll learn how to visualize additional data types as well as how to change the value of variables.

There are lots of good examples of creating a debugger visualizer for Visual Studio, but one thing that this is common is that all of them are written using Windows form. It is, however, possible to make a debugger visualizer in WPF, and thus display data in a much more sophisticated way using modern technology.

One of many improvements ASP.NET brings to the development table is in error handling. Adam Tuliper whips up a simple ASP.NET solution for handling those pesky and unexpected post-production errors.

There are many times when using SQL Server 2000 Query Analyzer to debug SQL statements is a better choice than debugging in Visual Studio .NET. In this article, Dina Fleet Berry explains why and walks you through the debugging process step-by step.

An ASP.NET HTTP Handler is a simple class that allows you to process a request and return a response to the browser. Unfortunately, when things go wrong, debugging an HTTP handler can be a little tricky. This article examines the process of debugging an HTTP handler in order to get everything working again.

This article introduces code contracts that specify statements in .NET programs that must prove valid.

Check-in policies help enforce your organization's development methodology and ensure that the code being checked in passes the necessary quality requirements. In addition to using the pre-defined check-in policies, you can create custom ones.

Simplify finding the entry you need from an event log.

Learn about several features relevant to developers in Visual Studio 2010 and the .NET Framework 4.0, such as parallel programming, XSLT debugging, new ASP.NET features, and new VB.NET and C# features that include the Chart control, XSD Designer, Lambda Expressions, and optional parameters.

Code is run in a debugger for two main reasons: examining the branches of code that are being executed, and examining data values to determine why the code is behaving in a certain manner. Inspecting data values can be significantly improved by customizing the debug information. See how that can be done in the Visual C++ debugger.

Apply the advanced trace log features of ADO.NET and improve your data access code.

Build a Windows Event Log Watcher Service Process to Export Event Log Entries as an RSS feed using System.Diagnostics.EventLog, EntryWritten, and EnableRaisingEvents.

Are you tired of hard-coding function names in trace messages? Have you ever used cut and paste to copy a trace statement and forgot to change the function name? There'll be no more wild goose chases because of bad function names when you determine the function name dynamically.

Tracing down errors in web applications and services is no easy task. To make it simpler, learn how to add trace statements to your code. They appear only when tracing is enabled on the web page or the web site.

For certain data sensitive web pages, you probably do not want users to use a web browser's back button because they may retrieve and repost a page from the browser's cache, which may cause an unexpected problem and sometimes crash your application. This is the so-called back button problem. Learn how to get rid of the little bug in an ASP .NET way.

The Whammy debugging tool permits you to use the .NET Framework to add detailed tracing information to your application in a very unobtrusive way.

Employ some useful .NET features to build an auto profiler, which a consumer can use to time any statement, method, or larger block of code just by calling a couple of methods.

More on ASP.NET 2.0's master pages: Here you see the various ways of specifying the master page to use and ways to work with master pages programmatically.

For complex data types, the traditional display offered by debug windows is inadequate. Visual C++ 2005 makes a dramatic upgrade to the variable display, offering a number of improvements in the way you can examine data during a debug session.

All the best software development practices and testing efforts in the world cannot guarantee that there are no intermittent or unexplainable application issues when in production. Worst case scenario being application hangs and crashes. This article shows how to take dumps of .NET applications and analyze them. This helps developers to understand the issue and find the faulty code.

Discover how to add functionality for debugging and tracking an application's execution path.

Paul uses a Blackjack program to demonstrates how to debug a hosted assembly.

Three aspects of .NET programming can make debugging and testing a ton of fun and help you come off as a real pro when you deliver bulletproof code.
