Use Custom Visualizers for C++ Objects

Sometimes the default view of objects in the debugger isn't enough, especially if you operate on complex data structures. Here's one way to alter the view and use a customized one.

It's Safe to Handle Unhandled Visual Basic and C# Exceptions

Pile on the exceptions, and .NET will have your back with the tools it provides at your disposal.

Life Without On Error Resume Next

The alternative to that simple error-handling combo is the Try...Catch, but it's not as simple as wrapping up your code with it.

Debugging Mouse Clicks and Dragging in C++

Debugging mouse events is especially confusing, because when the debugger stops the code, most of the events go away! What tactics can we use in these situations?

Magic Forms Access in Visual Basic and C#

Look behind the curtain on this one, and you'll see that code is quite magical in and of itself.

Strategies for Debugging Lots of C++ Objects Effectively

When you have code that is called for many objects it's hard to go through all them and just check line by line. How can you more efficiently debug lots of code?

Tricks with Goto in Visual Basic and C#

Goto statements, whether they're used in Visual Basic or C#, can be confounding as to their purpose in some contexts.

How Helper Variables Can Simplify Debugging

If the data you work with is complex and hard to understand, it's easy to get stuck on them when debugging. Add helper variables to make data much simpler to use and comprehend.

Local Static Variables in Visual Basic and C#

Here's another area where the two languages differ.

Cool Case Clauses in Visual Basic and C#

Each language treats case clauses differently, but there's a way you can make them less boring in C#.

Understand Conditional Breakpoints in C++

Standard function breakpoints probably help in most of the debugging sessions. But, sometimes, there's simply too much code to check, too many objects or cases. What if you want to filter out code that generates a breakpoint? Here's a look at conditional breakpoints.

Overcoming Escape Sequence Envy in Visual Basic and C#

C# might be more elegant with escape sequences, but that doesn't mean Visual Basic is weaker in this area.

Make The Debugger Focus on Code That's Important To You

When you debug a C++ application, the debugger can take a number of detours through lots of trivial functions or code from third-party libraries. You can filter out those unnecessary paths and have the debugger focus on just the code you want.

It's All About Character in C# and Visual Basic

How C# and Visual Basic handle characters and single-character strings is a bit inconsistent. There's no tidy solution, but it's something you do need to know.

Test Out Code Variations at Runtime Using a Static Variable

Recompiling source code while debugging is possible, but sometimes your C++ project might not be configured to use it.
