VB Decompiler is a decompiler for applications (EXE, DLL or OCX) written in Visual Basic 5.0/6.0. As you know, programs in Visual Basic can be compiled into interpreted p-code or into native code.
Since p-code consists of high-level commands, there is a real possibility to decompile it into the source code (of course, the names of variables, functions, etc. will not be decompiled).
VB Decompiler restores many p-code instructions and although there is a long way to the generation of the source code that can be compiled, the decompiler will make analyzing the program algorithm much easier and partially restore its source code.
If a program was compiled into the native code, restoring the source code from machine instructions is not possible. But VB decompiler can help to analyze the program even in this situation as well. It contains a powerful disassembler that supports Pentium Pro commands including MMX and SSE.
It allows you to disassemble all functions. In addition, VB Decompiler includes a code analyzer that will search for all API function calls or string references in the entire disassembled code and will change them into comments for the analyzed strings.
In general, VB Decompiler is an ideal tool for analyzing programs and it is perfect if you lose the source code and need to partially restore the project.
Here are some key features of "VB Decompiler":
· Decompiling forms (frm and frx) and usercontrols (ctl) object files;
· P-code decompiling (with decompile GUID objects);
· Disassembling native code procedures (with power Pentium Pro disassembler, supporting MMX and FPU instruction sets);
· Syntax coloring in decompiled code;
· String reference list and search engine;
· Fast decompiling speed.
Requirements:
· Pentium 166
· 32Mb RAM
Limitations:
· Some features are disabled: P-Code decompiling, code obfuscating and Native Code disassembling optimization
