Encode QR Code ISO/IEC18004 In Visual Studio .NET
Using Barcode generation for .NET Control to generate, create QR Code image in Visual Studio .NET applications.
Let s use crash mode as an example of how to use ADPlus to generate a dump file for 08SimpleExcexe Start by running the 08SimpleExcexe application:

Generate QR Code ISO/IEC18004 In C#
Using Barcode drawer for .NET Control to generate, create QR Code JIS X 0510 image in .NET applications.
The crash switch puts ADPlus into crash mode, the pn switch tells ADPlus the name of the process to monitor, and the y sets the symbol path to be used throughout the ADPlus execution The beauty of using the pn switch is that it can monitor any number of instances of any given process name by name When execution has finished, ADPlus puts the resulting log files under a directory of the Windows debuggers installation path The name of the directory takes on the following structure:

Using Barcode encoder for VS .NET Control to generate, create Code128 image in Visual Studio .NET applications.
Note that the default path can be changed by using the o switch In the preceding directory, there are several files, but the most important ones dmp files, which contain all the dump information from the run As you can are the * see, there are several dump files collected Why do we have more than one dump file per crash Well, ADPlus automates the process of collecting dump files and as such generates dump files when certain preset conditions occur during execution The name of the dump file gives you the necessary clues to figure out the reason the dump file was generated For example, in our previous run, ADPlus generated the following dump files:

Generate ECC200 In C#
Using Barcode drawer for .NET Control to generate, create Data Matrix 2d barcode image in VS .NET applications.
ADPlus generated a full dump file when the first chance process shutdown event occurred, followed by a full dump file when the NET exception occurred (second chance) Do we need all of these dumps for our particular run No In our particular case, the most interesting dump file is the second chance NET exception However, there are situations where periodic generation of dump files can be very useful, as it can yield a historical perspective of the systematic deterioration of a process ADPlus even offers a powerful way for the user to configure how often information should be collected and under what conditions, essentially providing a scripting front end for the debuggers You can learn more about the scripting capabilities of ADPlus in the debugger documentation It is important to note that ADPlus does not do anything magical via its scripting engine It simply takes a user-friendly way of specifying debugger directives and translates them into pure and automated debugger commands You can see how the user-friendly configuration actually translates to the debugger commands by looking at the directory called CDBScripts located in the same directory as the dump files In our example, the CDBScripts directory contains a file called PID-4448__08SimpleExcexecfg, which contains all the debugger commands used in that ADPlus session

The last important point about ADPlus is how we can control what type of dump file gets generated when a fault occurs There are four command-line switches that control this behavior:
Code 39 Extended Creator In VB.NET
Using Barcode encoder for .NET Control to generate, create Code 39 image in Visual Studio .NET applications.
FullOnFirst This switch causes ADPlus to generate a full dump file when a first chance exception occurs MiniOnSecond This switch causes ADPlus to generate a mini dump file when a second chance exception occurs -NoDumpOnFirst This switch tells ADPlus not to generate a mini dump file when a first chance exception occurs This can come in handy as applications sometimes generate first chance exceptions that are gracefully handled -NoDumpOnSecond This switch tells ADPlus not to generate a mini dump file when a second chance exception occurs

ADPlus is a convenient, powerful, and flexible tool for monitoring and gathering data from faulty processes In this section, we covered the basics of the tool, and it is well worth your time to investigate the other powerful features such as the scripting capabilities and defining custom exception handlers that allow you to generate dump files when custom exceptions occur Now that we have shown two of the most common ways of generating dump files, it is time to make use of the dump files and see what the troubleshooting process looks like
