Windev 25 Dump Exclusive ^new^ Now
In WinDev 25, the function dbgSaveDebugDump is used to generate a .wdump file. This "exclusive" file acts as a snapshot of the application's runtime environment, including:
The Call Stack: Showing the sequence of functions that led to the current state.
Variable Content: Providing the values of all variables at the exact time of the dump.
Runtime Information: Capturing system-level data to help developers "reposition" the debugger later. How to Use a .wdump File To analyze a dump file in WinDev, developers typically:
Open the File: Drag and drop the .wdump file into the WinDev window editor or use the Home > Open menu.
Analyze the State: Use the integrated debugger to inspect the application state without needing the live environment where the error occurred.
Resolve "Exclusive" Issues: If "exclusive" refers to exclusive file access errors (a common issue in database management), the dump can help identify which thread or process is holding a lock on a data file. Strategic Importance for Developers Using dumps effectively allows for:
Post-Mortem Debugging: Fixing bugs that only happen on a client's machine.
Efficiency: Reducing the time spent trying to reproduce intermittent "ghost" bugs.
Integrity: Ensuring the software remains stable by identifying memory leaks or locking conflicts. windev 25 dump exclusive

While "dump exclusive" isn't a standard marketing term for , it typically refers to a specific technical error or troubleshooting scenario where a developer needs to analyze a memory dump during an exclusive file access conflict. In WINDEV development, "exclusive" usually relates to file access modes.
Below is a blog post draft addressing the common challenges and solutions regarding exclusive file access and error dumping in
Troubleshooting "Exclusive Mode" and Error Dumps in WINDEV 25 If you’ve been working with
, you know it brought significant upgrades—like the introduction of Smart Controls
and enhanced PDF management. However, legacy challenges like exclusive access errors and the need for error dumping remain critical for any serious developer. 1. What is an "Exclusive" Error?
In WINDEV, an "Exclusive Mode" error typically occurs when a process attempts to access a data file (
) that is already locked by another user or another part of your application. The Conflict:
One user might be performing a reindex or a structural update (which requires exclusive access), while another is trying to read data. The Result: In WinDev 25, the function dbgSaveDebugDump is used
The application may throw a native HFSQL error (e.g., Code 70010 or 70907), often accompanied by a dump of the module WD250HF.DLL 2. Dealing with the "Dump"
When WINDEV crashes or encounters a fatal database error, it generates an error dump
. This file contains the "state" of the application at the moment of failure. Why it Matters: The dump includes the EIT_PILEWL
(call stack), which tells you exactly which line of WLanguage code triggered the conflict. remote debugging
features in WINDEV 25 to analyze these dumps from another machine, allowing you to see exactly what went wrong in a production environment. 3. Practical Solutions for Exclusive Conflicts
To avoid the dreaded exclusive access crash, follow these best practices: Check File Status: HListConnection to see who is currently locking the file. Manage Auto-Identifiers:
Sometimes "duplicate" errors in exclusive mode aren't about real duplicates, but the internal auto-ID counter getting out of sync. Use
to reset these counters if your application throws a dump during a write operation. Environment Compatibility:
Remember that WINDEV 25 can coexist with older versions on the same machine, but ensure you aren't trying to open the same project or files in two different versions simultaneously, as this frequently causes exclusive lock dumps. Right-click the process in Task Manager > Create
The "dump" isn't your enemy—it's the roadmap to fixing the "exclusive" access bugs that plague multi-user environments. By leveraging the diagnostic tools in the HFSQL Control Center
and the WINDEV 25 debugger, you can turn these crashes into stable, production-ready code. hfsql control center version 24.77c user name issue

If you're looking to create a paper or document about WinDev 25 and its "Dump Exclusive" feature or issue, here are some general guidelines and tips:
Introduction
WinDev 25 continues PC SOFT’s long-standing approach: provide a single environment that accelerates the full application lifecycle — from UI design and database integration to deployment and cross-platform compilation. Target audiences include enterprise developers, independent software vendors, and teams seeking fast, low-code-friendly development with strong built-in components.
Introduction
In the ecosystem of WinDev 25, data is king. Whether you are managing a local shop management system or a complex corporate ERP, the integrity of your HyperFileSQL (HFSQL) database is non-negotiable. Among the myriad of control commands and backup procedures available to developers, one phrase stands out for its power and potential peril: "Windev 25 dump exclusive."
If you have spent any time in the WinDev 25 IDE or perused the HFSQL Control Center (HCC), you have likely stumbled upon the HDump function or the "Dump exclusive" checkbox. To the uninitiated, it looks like just another backup option. To the seasoned developer, it is the golden key to a consistent, point-in-time snapshot of a live database—but a key that must be turned with extreme caution.
This article will leave no stone unturned. We will explore what "dump exclusive" means, how it differs from a standard dump, when to use it, how to implement it in Windev 25 code, and the critical performance implications for your production environment.
Part 4: How to Implement "Dump Exclusive" in WinDev 25 Code
You won't find a button labeled "Dump Exclusive" in the WinDev 25 ribbon by default. You must invoke it programmatically using the HDump function or the HBackup function.

3. Using Windows Task Manager (external dump, not exclusive to WinDev)
- Right-click the process in Task Manager > Create dump file.
- This creates a
.dmpfile (not native WinDev format).
Limitation: Not exclusive – WinDev may continue writing to its memory, causing inconsistencies.
