Enabling or disabling Just-In-Time debugging sets a registry key, and administrator privileges may be required to change that key.

To open Visual Studio as an administrator, right-click the Visual Studio app and choose Run as administrator. Just-In-Time debugging may still be enabled even if Visual Studio is no longer installed on your computer.

From the Windows Start menu, run the Registry Editor regedit. In the Registry Editor window for bit computers, locate and delete the following registry entries:. If the following registry entries are present, or your computer is running a bit operating system, delete the following entries:. By default, Windows Form apps have a top-level exception handler that lets the app keep running if it can recover. If a Windows Forms app throws an unhandled exception, it shows the following dialog:.

To enable Just-In-Time debugging instead of standard Windows Form error handling, add these settings:. In the system. If you want to debug a non-optimized release build, however, you must set DebuggableAttribute by adding the following line in your app's AssemblyInfo. For more information, see DebuggableAttribute. You must have Visual Studio installed to follow these steps.

For more information about creating projects in Visual Studio, see Walkthrough: Create a simple application. In a more complex callback, you could use this information to determine if the memory is critical to dump analysis, and whether the dump should be aborted. It is the GC heap that you need in a dump of a managed process because the Son of Strike SOS debugger extension requires intact data structures from within the GC heap to interpret the dump.

With this debugging session, you could load the SOS debugger extension and run commands to return the heap information this is an example of using domain knowledge. Alternatively, you could use heuristics. This collects more memory than absolutely necessary but still makes a significant saving by excluding the application itself.

It then uses the same MemoryCallback code used in the MiniDump04 sample to include the memory in the dump. The answer is a bit out-of-the-box. When the debugger needs to access a missing image region in a non-Full dump, it obtains the data from the image file instead. It works particularly well with native applications, because the binaries compiled are the ones used and are therefore available on your internal build server and pointed to by the PDBs.

This is still a savings because multiple dumps can be taken quickly, and then a single large application image file collection can be done without outage. To simplify the file collection, you could use the ModuleCallback to write out a script that collects the modules files referenced in the dump. Changing the standalone application to use Sysinternals ProcDump v4.

You no longer have to implement all of the code associated with calling MiniDumpWriteDump, and, more important, all of the code to trigger the dump at the right time. The MiniDump06 sample see Figure 14 includes the callback code from MiniDump05 with just a few modifications. Note that the callback is invoked with different callback types than the ones described in my samples when a Full dump -ma is being taken refer to the MSDN Library for the documentation.

Sysinternals ProcDump procdump. After procdump As such, debugging your bit DLL is quite tricky because the launched application is not the desired target. The easiest thing to do to support debugging your bit DLL is to copy the temporary procdump In this way, no extraction will occur and your DLL will be loaded in the application you launch from within the debugger Visual Studio, for example.

Determining the origin of crashes and hangs is not easy when you can afford only a Mini dump. Making a dump file with additional key information solves this without incurring the expense of a Full dump. When writing a callback, make sure you spend the time to understand the exact layout of memory within your application. Take Sysinternals VMMap snapshots and use dumps of the application to delve into the details. Making smaller and smaller dumps is an iterative approach.

You may need to use both heuristic and domain knowledge approaches to get you to your goal. You can help your decision making by modifying the target application. This browser is no longer supported.
