By John Robbins
Within the predecessor quantity of Debugging purposes for Microsoft .NET and Microsoft home windows, which handled visible uncomplicated 6, John Robbins broke new floor through codifying the options and methods all for debugging Microsoft home windows functions. during this significantly revised and masses longer model (in protecting with Microsoft's large shift to the .NET architecture), Robbins achieves nice development in creating a right expert self-discipline out of debugging - and in exhibiting easy methods to layout software program to maintain insects from showing within the first place.The maximum worth of Robbins' paintings is in his remedy of insects' origins in unsuitable software program layout and their later manifestation in defective coding perform. He explains in nice aspect, for instance, tips to use assertions (in live performance with blunders dealing with) to maintain undesirable info from entering into software program modules and inflicting difficulty. This insurance is why your improvement staff may still learn this e-book ahead of getting too some distance down the improvement path.If you are already performed along with your software program process and simply cannot make it paintings correct (and, certainly, the cut-off date of demise is looming), this ebook deals wish in addition. are looking to write a mode that you just invoke manually in simple terms whilst this system is at a breakpoint within the debugger? This publication exhibits how. want plenty of information on how you can upload assembly-language code in your visible C++ .NET software program? you can find them right here. there is a lot of knowledge approximately how debuggers do their paintings regularly, too. to place it concisely, this publication incorporates a career's worthy of knowledge on tips to maintain insects to a minimal and music them down after they happen.

For Native Code, Treat Warnings as Errors—Mostly Compared to managed code, native C++ not only lets you shoot yourself in the foot when it comes to compilation issues, but it also hands you the loaded gun and cocks it for good measure. When you get a warning in C++ code, you're really being told that the compiler is taking a wild guess as to what you intended. A warning such as C4244 ('conversion' conversion from 'type1' to 'type2', possible loss of data), which is always reported on conversions between signed and unsigned types, is an excellent example.
In addition to making sure data types are explicit, the managed code compilers can do much more to help you with errors if you let them. As usual, the trick to debugging smarter is not one big gesture, but taking advantage of lots of small steps along the way. Making your tools as smart as possible is one of those steps. NET\Visual Basic and Visual C#\Reference\Visual C# Language\C# Compiler Options\Compiler Errors CS0001 Through CS9999, you'll see all the compiler errors for C#. ) As you scroll down the list of errors, you'll notice that some say Compiler Warning and indicate a level, for example, Compiler Warning (level 4) CS0028.
When you don't have any landmarks, you can end up going around in circles. When your application crashes, you need a similar kind of landmark to help point you in the right direction so that you're not wandering around in the debugger. The first big landmark for crashes is the base address of your dynamic-link libraries (DLLs) and ActiveX controls (OCXs), which indicates where they loaded into memory. When a customer gives you a crash address, you should be able to narrow down which DLL it came from quickly by the first two or three numbers.
