The VC toolset is optional; if present it is used for editbin.exe to modify the stack size used by ILSpy.exe from 1MB to 16MB, because the decompiler makes heavy use of recursion, where small stack sizes lead to problems in very complex methods. Open ILSpy.sln in Visual Studio. NuGet package restore will automatically download further.

Perfect source code recovery solution for Visual Basic 5.0/6.0 applications and fast disassembler for Visual Studio .NET compiled apps.
Best code recovery solution for Visual Basic 5.0/6.0 applications and fast disassembler for Visual Studio .NET compiled apps.

Source code loss is a very serious problem for many software developers. As most Visual Basic 5.0/6.0 applications were developed a long time ago, their source code (.vbp, .frm, and .bas files) has already been lost due to migrating to a new computer, replacing a hard drive, etc. Based on the experience of most of our customers, we can say that losing source code can be a tragedy. Just imagine that you have written a program, spending a lot of effort, time, and money, but now all that is left is the compiled program (the EXE file with DLL libraries).

Some day you may suddenly discover that your source code is gone. Maybe you have upgraded your PC or migrated your data to another cloud, or your hard drive just failed, and you do not have a backup. You are starting to panic. What should you do? Just take VB Decompiler and decompile most parts of your project! VB Decompiler will recover as much as possible of your source code with a higher success rate than any competitive product.

Visual Basic has two different compilation modes: p-code (pseudo code) and native code (assembler). VB Decompiler can restore the source code from p-code as close to the original one as possible, so after a few modifications you can get some really workable source code. Of course, in case of a program compiled to native code, the decompilation success rate will be lower, but you still can recover up to 70 percent of the original source code. VB Decompiler has a few powerful built-in tools: an x86/x64 disassembler, an emulator for assembler commands, and a tracing engine. Thanks to them, the result of decompiling the binary code will be very close to Visual Basic code. Because of the diversity of modern code optimization and code protection methods, the result will not always be perfect. But in a dire situation like that, VB Decompiler can really help you with software analysis and reverse engineering.

If you develop your software in Visual Studio 2019 (or in VS 2015, 2013, or lower), using .NET Framework - that's no problem! VB Decompiler can easily restore the code structure from the assembly tables and will be useful for disassembling and analyzing the IL code of Visual Basic .NET, C#, or other .NET assemblies.

VB Decompiler does not require that you install .NET Framework. It works fine on any 32-bit or 64-bit Windows system, as well as on any 32-bit or 64-bit Linux system (with Wine), without requiring that you install any additional software.

As you can see, VB Decompiler is an ideal source code analyzing and restoring tool. It is a must-have for VB developers who value their effort, time, and money.

Decompile Dll Online


[ 🌐 📩 🔥 ]

Let's be honest, there is no reason to remember how to decompile stuff with the various tools available. Wouldn't it be nice to just decompile the $h*! out of things right off the fingertips in Visual Studio Code? Well, here we go:

This extension decompiles ..

  • Binary executables for various platforms
    • as supported by Ghidra; Windows PE, Linux ELF, IOS, etc.
    • or IDAPro (Experimental, Windows Only for now)
  • Java Jar archives and compiled Classes
  • Android APK's
  • Python .pyc and .pyo
  • Ethereum/EVM based Smart Contracts
    • (Experimental, Linux/MacOs only)

Just right-click → Decompile on a supported executable and wait for the magic to happen.

The decompilation result is added to a temporary sub-workspace. You can right-click → Download files to your local file-system right from the sub-workspace.

Have phun 🙌

Tour

macOS

Windows (Ghidra vs. IDAPro)

Ethereum Smart Contract

Save the EVM byte-code in a file with extension .evm, then right-click → Decompile.

Setup

Requirements: General
  • Requires Java (11+) to be installed system-wide. Just install the latest JRE/JDK for your OS (e.g. OpenJDK, Oracle JDK).
  • Other tools are bundled with the extension. Just make sure Java is available in your PATH.
Requirements: Binary executables (Ghidra / IDA Pro)
  • Requires a working installation of Ghidra (← Download) to decompile executables
    • either available in PATH (like when you install it with brew cask install ghidra on os-x; or set-up manually)
    • otherwise please specify the path to the executable <ghidra>/support/analyzeHeadless in code → preferences → settings: vscode-decompiler.tool.ghidra.path and make sure that the analyzeHeadless script runs without errors (and is not prompting for the JDK Home 🤓). Here's a sample Ghidra config for Windows:
  • (Experimental; Windows Only) Optional a licensed version of IDA Pro with decompiler support.
    • specify the path to the idaw executable in code → preferences → settings: vscode-decompiler.tool.idaPro.path, e.g. c:IDA68idaw.exe.
    • set preference to idaPro (experimental Windows Only) in code → preferences → settings: vscode-decompiler.default.decompiler.selected.
    • we'll automatically try to run 32 and 64bits idaw on the target application (preference on what executable is configured by you)
    • If you're running <= IDA Pro 6.6 and the normal IDA decompilation mode does not work you can try the set preference to idaPro legacy hexx-plugin (experimental Windows Only) in code → preferences → settings: vscode-decompiler.default.decompiler.selected. Note: Use this method only if the normal IDA Pro mode doesnt work. Caveat: idaw*.exe must not be in a path that contains spaces, ask @microsoft why 😉.
Requirements: Python
  • Python decompilation requires pip3 install uncompyle6 (see settings)
    • specify the uncompyle6 script location in code → preferences → settings: vscode-decompiler.tool.uncompyle.path or set to uncompyle6 if it is available in PATH
Requirements: Smart Contracts (EVM byte-code)
  • The pseudocode generator panoramix/eveem requires a working installation of python3.8 or newer.
    • specify the python3.8 path in code → preferences → settings: vscode-decompiler.tool.python38.path (e.g. /usr/local/opt/[email protected]/bin/python3.8 (macos/homebrew))
    • make sure pip for python3.8 is installed
    • install panoramix dependencies: $ /usr/local/opt/[email protected]/bin/python3.8 -m pip install coloredlogs requests web3 timeout_decorator
  • Note: Panoramix is run in local mode. EVM byte-code is not sent to eveem.org.
    • It will attempt to download a function signature database on first load.
    • It will cache files to <userhome>/.panoramix.
  • No Windows support :/ (see this issue).
Setting tool preferences

code → preferences → settings:

  • Set default decompiler preference to ghidra (default) or idaPro (experimental Windows Only) (requires a licensed version of IDAPro + Decompiler)
    • vscode-decompiler.default.decompiler.selected
  • Set preference for java decompilation to JADX or JD-CLI (default)
    • vscode-decompiler.java.decompiler.selected
  • Set preference for android apk decompilation to dex2jar + jd-cli (slow) or JADx (default)
    • vscode-decompiler.apk.decompiler.selected'

Troubleshooting & FAQ

  • (macOs) 'macOs cannot verify the developer of 'decompiler' ..
    • Follow the fix outline in https://support.apple.com/en-za/guide/mac-help/mh40616/mac.
    • Verify that you've downloaded ghidra from the original website, verify checksums. Note: you're running an NSA tool on your computer, just saying.
    • Open the <ghidra-install-folder>/Ghidra/Features/Decompiler/os/osx64 in finder, Ctrl+mouseClick on decompileopen (you only need to do this one time).
