SMS: Dependency Walker for Win32 (Depends.exe)

MORE INFORMATION

Dependency Walker for Win32 (Depends.exe) is a diagnostic tool that that you can use to determine which 32-bit program files are required to run a particular program or load a particular dynamic-link library (DLL). The Depends.exe features include:

• The minimum set of files required to run a particular program or load a particular DLL.
• Why a certain module is being loaded with a particular program.
• The complete path for all the modules being loaded for a particular program.
• The base addresses of each module being loaded.
• The version of the file and/or computer type that it was created for.

Dependency Walker recursively scans all dependent modules required by a particular program. During this scan it performs the following tasks:

• Detects missing files. These are files that are required as a dependency to another module. A symptom of this problem is the "The dynamic link library Bar.dll could not be found in the specified path..." error message.
• Detects invalid files. This includes files that are not Win32 compliant and files that are corrupted. A symptom of this problem is the "The program or DLL Bar.exe is not a valid Windows image" error message.
• Detects import/export mismatches. The tool verifies that all functions imported to a module are actually exported from the dependent modules. All unresolved import functions are flagged with an error message. A symptom of this problem is the "The procedure entry point Name could not be located in the dynamic link library Bar.dll" error message.
• Detects circular dependency errors. This is a very rare error, but it can occur with forwarded functions.
• Detects mismatched computer module types. This occurs if a module built for one type of computer tries to load a module built for a different type of computer.

You can run this tool from a command prompt or from within Windows.

The syntax of the command is: depends.exe
