MiniDump Wizard application allows to experiment with MiniDumpWriteDump and MiniDumpCallback functions without writing code. It is possible to specify a combination of MINIDUMP_TYPE flags that will be passed to MiniDumpWriteDump function, and it is possible to respond to MiniDumpCallback calls in a series of dialogs.

See this article for more information about minidump creation options, including MINIDUMP_TYPE flags and MiniDumpCallback function.

How to use MiniDump Wizard

When you start MiniDump Wizard, it shows a dialog window that allows to select MINIDUMP_TYPE flags that will be passed to MiniDumpWriteDump function. In the same dialog, you can specify the callback types that you want to respond to.

The dialog also allows to specify the target process. You can specify the process identifier (pid) of the target, or you can create the minidump for MiniDump Wizard process itself. In order to explore the contents of minidumps created for MiniDump Wizard process, MiniDumpWiz.pdb file is provided.

After you have specified all settings in the first dialog, pressing Next will either create the minidump (if no callback options have been selected), or will show the dialog pages for the specified calls to MiniDumpCallback function, where you can inspect the data passed to the callback and respond to the callback call (by using the dialog controls to modify the callback's return value, the contents of MINIDUMP_CALLBACK_OUTPUT structure, or both).

The minidump file will be called MiniDumpWiz.dmp. Currently there is no way to change its name (this is to keep the application as simple as possible).

Download

MiniDump Wizard depends on DbgHelp.dll (DbgHelp.dll 6.3.17.0 or newer is required). The DLL must be in the same directory as MiniDump Wizard executable. You can download the DLL with MiniDump Wizard, or you also can download MiniDump Wizard only and obtain DbgHelp.dll from another source (the latest version of DbgHelp.dll is usually supplied with Debugging Tools for Windows).
