Recommendation

If you're considering using WinDev 27, weigh the pros and cons carefully. If you're already using it, you may want to explore alternative options, such as:

  1. Visual Studio: A widely-used, feature-rich IDE with excellent support and a large community.
  2. Delphi: A popular, object-oriented IDE with a strong focus on Windows and mobile app development.

Ultimately, the decision to "dump" WinDev 27 depends on your specific needs and priorities as a developer. dump windev 27

Whether you are trying to debug a 64-bit application or weighing the pros and cons of sticking with the platform, this guide explores everything you need to know about "dumping" WinDev 27. 1. The Technical Dump: Using dbgSaveDebugDump

If you are facing a runtime crash that you can't reproduce in the editor, WinDev 27 provides a built-in way to "dump" the application's current state. This creates a .wdump file that captures the call stack and variable values at the exact moment of failure.

How to Generate: Use the dbgSaveDebugDump function in your WLanguage code. You can save it to a specific path using fExeDir() to ensure it's easily accessible.

How to Analyze: Simply drag and drop the .wdump file into the WinDev 27 editor. This "repositions" the debugger, allowing you to inspect the memory and variables as if you were running the code live.

Critical Requirement: You must open the dump using the exact same version of the WinDev editor used to generate the executable. 2. The "Dump WinDev" Movement: Why Developers Are Leaving

Beyond the technical definition, "Dump WinDev 27" has become a rallying cry for developers frustrated by the platform's limitations. Despite being a powerful Rapid Application Development (RAD) tool, several factors are pushing users toward alternatives like C#, Java, or web-native frameworks: Sharing your source code with the SCM - PC SOFT

A "dump" in the context of WINDEV 27 primarily refers to the dbgSaveDebugDump function, which saves a debug dump file (.wdump) to capture the application's state—including the call stack and variable values—at a specific moment for later analysis in the debugger [1.2.9, 1.3.3]. Technical Review: WINDEV 27 Debug Dumps

The dump feature is a critical diagnostic tool for developers to troubleshoot runtime issues without needing an active live debugging session.

Functionality: The dbgSaveDebugDump function dbgSaveDebugDump records runtime information into a .wdump file [1.2.9].

Usage: To analyze a dump, developers can simply drag and drop the .wdump file into the WINDEV, WEBDEV, or WINDEV Mobile editor [1.3.3]. Key Data Captured: The complete call stack at the time of the call. The content of all variables present in memory.

Developer Benefit: It allows for "post-mortem" debugging, enabling you to inspect what happened on a client's machine or a remote server where live debugging is not possible [1.2.9]. General Review of WINDEV 27

WINDEV 27 is a Rapid Application Development (RAD) environment designed for building Windows, Linux, .NET, and Java applications [1.3.6]. Key Features introduced in Version 27:

5.1 Identify the Target Process

Run the WinDev 27 application. Use Process Hacker to locate the main executable and loaded WD270.DLL.

tasklist /m wd270*.dll

Example output:

MyApp.exe  1234  WD270.DLL, WD270HF.DLL

Step-by-Step: Dumping a WinDEV 27 Process

Why Dump a WinDEV 27 Application?

Before diving into the "how," it is essential to understand the "why." WinDEV 27 applications are compiled into native executables (.exe) but rely heavily on:

  • A specific runtime library (WD270.DLL, WD270VM.DLL, etc.).
  • A proprietary p-code or hybrid compilation model (partly native, partly interpreted).
  • Encrypted or obfuscated strings and resources.
  • HyperFileSQL databases often embedded within the binary or run as a service.

Common legitimate reasons to dump a WinDEV 27 process include:

  1. Forensic Analysis – Extracting injected malicious code from a compromised WinDEV app.
  2. Debugging Crashes – When standard debuggers fail, a memory dump reveals heap corruption or stack traces.
  3. Reverse Engineering for Legacy Maintenance – The original source code (.WDG or .WWL files) is lost, but the binary runs.
  4. Password or Key Recovery – Some WinDEV apps store hardcoded credentials in plaintext or simple XOR ciphers within memory.

3.3 Resource Dumper (Windows API)

Windev stores forms, images, and reports as custom resources.

Tool: reshacker, ResourceHacker, or custom Python with win32api.

Example (Python with pefile):

import pefile
pe = pefile.PE("app.exe")
for rt in pe.DIRECTORY_ENTRY_RESOURCE.entries:
    print(hex(rt.struct.Id))

Limitation: Forms are not stored as standard .dfm (Delphi) or .resx; they are a proprietary binary format. Dumping gives raw data, not a reconstructable source.

1. Executive Summary

Windev 27 is a RAD (Rapid Application Development) tool by PC SOFT that generates native Windows executables (.exe) often relying on a proprietary framework (WD28*.dll). Unlike .NET or Java, these are compiled C/C++ hybrid binaries with specific runtime characteristics (hyper-file system, specific string encoding, event-driven loops).

“Dumping” typically refers to:

  • Memory dumping (extracting the process memory from RAM).
  • Resource dumping (extracting embedded windows, reports, or scripts).
  • Decompilation/Reverse engineering of the binary.

1. General Overview

  • Version: 27 (Released roughly in 2021/2022).
  • Core Architecture: RAD (Rapid Application Development) focusing on WLanguage.
  • Target Platforms: Windows (32/64-bit), Linux, .NET assemblies, Java (limited).
  • Database Engine: HyperSQL (HFSQL) – Native, no external database required, supports up to 2 billion records per file.

Tools Limitations and Alternatives

  • Volatility Framework (memory forensics) – Does not have a WinDEV plugin. You would need to manually carve artifacts.
  • GDB on Wine – Running the WinDEV 27 app under Wine on Linux then using gdb + generate-core-dump can sometimes bypass Windows anti-debugging tricks.
  • Commercial solutions – Hex-Rays does not support WinDEV p-code. No mainstream decompiler exists.

Your best bet remains manual memory carving with a hex editor and patience.
