1. Understanding WINDEV 17 Basics

Language: WLanguage (similar to Pascal + BASIC).
Project types: Windows executable, client/server, web (WebDev 17), or REST API.
Key files: .WWP (project), .WDW (window), .WWR (report), .WWM (menu), .WLI (analysis).

The Origin of the Term

You will not find "DumpTeam" in the official PC SOFT documentation for WinDEV 17. Instead, it is a portmanteau used by debugging experts: windev 17 dumpteam

Dump: A file containing the process memory, stack traces, and register states when a program crashes.
Team: The group of developers (or the collaboration between a developer and technical support) who analyze the dump.

Real-World Case Study: DumpTeam in Action

Scenario: A logistics company using WinDEV 17 for inventory management experiences random crashes every 3 hours on a Windows Server 2012 R2. Mastering WinDEV 17 Debugging: The Essential Guide to

Initial symptoms: The event log shows "Faulting module: wd170hf.dll, exception code: 0xc0000005." Language : WLanguage (similar to Pascal + BASIC)

DumpTeam process:

Support enables LocalDumps via registry for the inventory app.
After the next crash, a 540MB dump is uploaded to a shared drive.
Developer A opens the dump in WinDBG. The !analyze -v command reveals the crash occurs during HFSQL's memory reclamation (function HClose).
Developer B cross-references the MAP file. The fault offset maps to a window closing procedure where HClose() is called on a query that already failed silently.
Developer C modifies the code: Before HClose(myQuery), the team adds IF HIsOpen(myQuery) THEN HClose(myQuery) END.
Fix validated: The team deploys the patch. Crashes drop to zero.

Outcome: Without the DumpTeam workflow, the company would have spent weeks rewriting the entire module. The dump analysis took 90 minutes.
