Dump Windev 27

Dumping in WINDEV 27 refers to the process of creating a snapshot of an application's state, typically to troubleshoot crashes or analyze runtime behavior when a standard debugger isn't attached. Understanding Debug Dumps in WINDEV 27

In version 27, a dump file (often with a .wdump extension) serves as a "recorded" state of the application's runtime information. It captures the call stack and the contents of variables at the exact moment the dump was triggered. This is essential for debugging issues on remote client machines where developers cannot directly access the live environment. Methods for Generating a Dump

You can create these diagnostic files either programmatically through WLanguage or manually using standard Windows tools. 1. Programmatic Generation (WLanguage)

WINDEV 27 provides specific functions to automate dump creation when an error occurs or at a specific code point:

dbgSaveDebugDump: This function saves a dump of the current application state. It allows you to reposition the debugger later on that specific runtime information to inspect the stack and variable values.

dbgSaveMemoryDump: If dynamic auditing is enabled, this saves a memory dump into the audit file. If disabled, it opens a file picker for the user to manually name and save the dump. 2. Manual Generation (Windows Task Manager) dump windev 27

If an application is frozen or unresponsive, you can create a standard Windows dump file: Open Task Manager (Ctrl + Shift + Esc). Navigate to the Details tab.

Right-click the WINDEV application process (e.g., MyApp.exe). Select Create dump file.

Windows will provide the file path (typically in %LocalAppData%\Temp) once completed. How to Analyze a WINDEV 27 Dump

Once you have a .wdump file, you can analyze it directly within the WINDEV environment:

Opening the file: You can drag and drop the .wdump file into the WINDEV editor or go to the Home tab, expand Open, and select Open to load it. Dumping in WINDEV 27 refers to the process

Inspecting variables: The editor will load the state as if the debugger were paused at that moment, allowing you to trace the cause of the failure.

For standard Windows .dmp files, you may need external tools like WinDbg or BlueScreenView to identify faulty modules or drivers. Related Version 27 Diagnostic Features

Version 27 also introduced 173 common new features that aid in application stability, such as: dbgSaveDebugDump (Function) - PC SOFT

Step 3: Recover Resources (Windows, Reports)

WinDEV 27 stores window layouts in a compressed format inside the .rsrc section of the dumped PE. Use Resource Hacker (load the dumped .exe if you extracted the image section) or WinDEV Resource Extractor (a niche tool found on reverse engineering forums).

Look for:

• .WDM files – window descriptors
• .WDE files – report definitions
• .WDC files – HyperFileSQL control files

4. Attempting Decompilation to Windev Language

Conclusion: Not possible to recover original Windev code (WDL or .wdw/.wda).

• Windev compiles to native code, not p-code.
• No known decompiler maps native back to 4GL events.
• What can be recovered:
  • System API calls.
  • Text strings used in Info() or error messages.
  • Control titles/labels (if stored in clear).

3. Legal & Ethical Warning

Only perform these actions on applications you own or have explicit written permission to audit. Unauthorized dumping/reversing may violate copyright laws (DMCA, EUCD) and software licenses. This write-up is for educational and defensive security research.

Part 1: Why Would You Dump Windev 27?

Understanding the “why” helps you choose the correct dumping method.

| Scenario | Dump Type | Goal | |----------|-----------|------| | Application freezes or crashes randomly | Full process memory dump | Capture the exact state leading to the crash (post-mortem debugging) | | Database corruption | Logical data dump | Recover records from damaged .FIC files | | Migration to another DBMS (MySQL, SQL Server) | Data export | Extract tables into standard formats | | Performance analysis | Mini dump | Identify memory leaks or inefficient code |

Windev 27 uses a proprietary hyper-file system (HF Classic or C/S). Directly opening .FIC files in a text editor yields binary garbage. Dumping is the only reliable way to inspect content. 3. Legal & Ethical Warning
