Dependency Walker

Download.com Staff Feb 27, 2009

This is a very helpful tool for those who need extensive information about dependent modules. Dependency Walker's simple interface packs a lot of data in a small display, but keeps easy to operate.

This isn't a tool for inexperienced users. Even experts without programming experience may find some of the information here incomprehensible. However, those who want to trace dependent modules to troubleshoot problems will find it very easy to do with this application. You simply click a module to see extensive function information. It's then just as easy to drill down the function list to find matching items, or search for additional information at Microsoft Live Search. Dependency Walker makes it very easy to save the module and function information as text, spreadsheet, or its own image file.

The features and data presented aren't well explained. This program requires users know their stuff. Programmers will find Dependency Walker's simple, but informative approach very helpful. If you program, or simply need to troubleshoot a program this freeware executable would be a welcome addition to your USB toolbox.

Developer's Description

Dependency Walker scans any 32-bit or 64-bit Windows module (exe, dll, ocx, sys, etc.) and builds a hierarchical tree diagram of all dependent modules. For each module found, it lists all the functions that are exported by that module, and which of those functions are actually being called by other modules. Another view displays the minimum set of required files, along with detailed information about each file including a full path to the file, base address, version numbers, machine type, debug information, and more. Dependency Walker is also very useful for troubleshooting system errors related to loading and executing modules. Dependency Walker detects many common application problems such as missing modules, invalid modules, import/export mismatches, circular dependency errors, mismatched machine types of modules, and module initialization failures.
