VB Decompiler
Second method – Decompile by using fernflower (via command prompt) Rename “Minecraft.exe” in “Minecraft.jar”, with the method used for the JD-GUI to rename it in.zip. Open the Command Prompt, hitting the button tasto Windows + R, typing cmd and hitting Enter. Use the cd command to move to the directory the fernflower is in. VB Decompiler is a decompiler for programs (EXE, DLL, or OCX) written in Visual Basic 5.0 or 6.0. As you know, a VB program can be compiled either into interpreted p-code or into native code. Since p-code consists of high-level commands, it's possible to decompile it into source code (though, of course, you won't get the names of. Sep 5, 2018 — ex4tomq4.pro at WI.

Mar 03, 2011 Informatie (ENG) Exe2Aut is designed to be the easiest to use and most versatile decompiler for compiled AutoIt3 scripts one could think of. Simply drag and drop the executable onto Exe2Aut’s main window and the source script will be displayed. Unlike the decompiler that’s being shipped with AutoIt3, Exe2Aut is even capable of decompiling. Step – 2: Locate the executable file you want to decompile. Open the file you want to decompile in JustDecompile or just drag and drop your files (.dll or.exe) on the interface. I’m using the normal way. Just navigate to Open - File (s) or just press Ctrl + O on your keyboard and choose your file using File Explorer.

Since p-code consists of high-level commands, it's possible to decompile it into source code (though, of course, you won't get the names of variables, functions, etc.). VB Decompiler can restore many p-code instructions. It cannot produce compilable source code but makes it much easier to analyze the program's algorithm and partially restore its source code.
If some program was compiled into native code, you cannot restore the source code from machine instructions. But even in this situation, VB decompiler can greatly help you analyze the program, thanks to a powerful disassembler that supports Pentium Pro commands, including MMX and SSE. VB decompiler lets you to disassemble all functions. It includes a code analyzer too, which searches for all API function calls and string references in the disassembled code and converts them into comments for analyzed strings. In general, VB Decompiler is an ideal tool for analyzing VB programs. It's a must-have if you've lost some source code and need to partially restore your project!

When debugging a .NET application, you may find that you want to view source code that you don't have. For example, breaking on an exception or using the call stack to navigate to a source location.
Note
- Source code generation (decompilation) is only available for .NET applications and is based on the open source ILSpy project.
- Decompilation is only available in Visual Studio 2019 16.5 and later.
- Applying the SuppressIldasmAttribute attribute to an assembly or module prevents Visual Studio from attempting decompilation.

Generate source code
When you're debugging and no source code is available, Visual Studio shows the Source Not Found document, or if you don’t have symbols for the assembly, the No Symbols Loaded document. Both documents have a Decompile source code option that generates C# code for the current location. The generated C# code can then be used just like any other source code. You can view the code, inspect variables, set breakpoints, and so on.
No symbols loaded
The following illustration shows the No Symbols Loaded message.

Generate and embed sources for an assembly
In addition to generating source code for a specific location, you can generate all the source code for a given .NET assembly. To do this, go to the Modules window and from the context menu of a .NET assembly, and then select the Decompile source code command. Visual Studio generates a symbol file for the assembly and then embeds the source into the symbol file. In a later step, you can extract the embedded source code.
Extract and view the embedded source code
You can extract source files that are embedded in a symbol file using the Extract Source Code command in the context menu of the Modules window.
The extracted source files are added to the solution as miscellaneous files. The miscellaneous files feature is off by default in Visual Studio. You can enable this feature from the Tools > Options > Environment > Documents > Show Miscellaneous files in Solution Explorer checkbox. Without enabling this feature, you won't be able to open the extracted source code.
Extracted source files appear in the miscellaneous files in Solution Explorer.
Known limitations
Requires break mode
Generating source code using decompilation is only possible when the debugger is in break mode and the application is paused. For example, Visual Studio enters break mode when it hits a breakpoint or an exception. You can easily trigger Visual Studio to break the next time your code runs by using the Break All command ().
Decompilation limitations
Generating source code from the intermediate format (IL) that is used in .NET assemblies has some inherent limitations. As such, the generated source code doesn't look like the original source code. Most of the differences are in places where the information in the original source code isn't needed at runtime. For example, information such as whitespace, comments, and the names of local variables aren't needed at runtime. We recommend that you use the generated source to understand how the program is executing and not as a replacement for the original source code.
Debug optimized or release assemblies
When debugging code that was decompiled from an assembly that was compiled using compiler optimizations, you may come across the following issues:
- Breakpoints may not always bind to the matching sourcing location.
- Stepping may not always step to the correct location.
- Local variables may not have accurate names.
- Some variables may not be available for evaluation.
More details can be found in the GitHub issue: ICSharpCode.Decompiler integration into VS Debugger.
Decompilation reliability
A relatively small percentage of decompilation attempts may result in failure. This is due to a sequence point null-reference error in ILSpy. We have mitigated the failure by catching these issues and gracefully failing the decompilation attempt.
More details can be found in the GitHub issue: ICSharpCode.Decompiler integration into VS Debugger.
Limitations with async code
The results from decompiling modules with async/await code patterns may be incomplete or fail entirely. The ILSpy implementation of async/await and yield state-machines is only partially implemented.
More details can be found in the GitHub issue: PDB Generator Status.
Just My Code
The Just My Code (JMC) settings allows Visual Studio to step over system, framework, library, and other non-user calls. During a debugging session, the Modules window shows which code modules the debugger is treating as My Code (user code).
Decompilation of optimized or release modules produces non-user code. If the debugger breaks in your decompiled non-user code, for example, the No Source window appears. To disable Just My Code, navigate to Tools > Options (or Debug > Options) > Debugging > General, and then deselect Enable Just My Code.
Extracted sources
Source code extracted from an assembly has the following limitations:
- The name and location of the generated files isn't configurable.
- The files are temporary and will be deleted by Visual Studio.
- The files are placed in a single folder and any folder hierarchy that the original sources had isn't used.
- The file name for each file contains a checksum hash of the file.
Generated code is C# only
Decompilation only generates source code files in C#. There is no option to generate files in any other language.
