However, P-Code is not immune to reverse engineering, and there are tools that can help hackers and crackers to analyze and modify P-Code programs. One of these tools is WKTVBDebugger, a powerful and versatile tool that can perform static and dynamic analysis of VB P-Code programs. WKTVBDebugger was developed by Mr. Silver and Mr. Snow from the WKT team, and it is based on the Exdec engine, a famous VB decompiler created by Mr. eXoDia.

WKTVBDebugger v1 3 is the latest version of the tool, and it has many features that make it a useful tool for VB P-Code reverse engineering. Some of these features are:
It can load and analyze any VB P-Code program, regardless of the version of VB used to compile it.
It can display the P-Code instructions in a readable format, with comments and references to the original source code if available.
It can perform static analysis of the P-Code program, such as finding strings, constants, variables, functions, procedures, forms, controls, events, etc.
It can perform dynamic analysis of the P-Code program, such as setting breakpoints, stepping through the code, modifying registers and memory, viewing call stack, etc.
It can patch the P-Code program on the fly, by changing or inserting P-Code instructions.
It can dump the P-Code program to a file or clipboard, in various formats such as hex dump, assembly code, or source code.
