WinDev applications often require specific locking mechanisms to ensure data integrity. An "exclusive" dump generally occurs in two scenarios:
The Application Needs Exclusive Access: You are trying to perform an operation that requires total control (like HIndex, HModifyStructure, or HBackup), but another user or instance has the file open.
Another Process Has Exclusive Access: A backup tool, an anti-virus scanner, or another developer's test instance has locked the file, preventing your application from opening it even in shared mode. Common Solutions
Identify the "Locking" UserBefore jumping into code, check who is holding the file. Use the HFSQL Control Center to view "Connected Users." If you see active connections, you must close them before running operations that require exclusive rights.
Check Your HOpen ParametersIf your code explicitly asks for exclusive access, ensure it’s necessary.
// This will trigger a dump if ANYONE else has the file open HOpen(MyFile, hReadWrite + hExclusive) Use code with caution. Copied to clipboard
Switching to hShareReadWrite is usually the solution for standard multi-user environments.
Ghost ProcessesSometimes, an application crashes but the process stays alive in the background. Check your Task Manager for any lingering .exe instances of your project. If the process is stuck, it maintains its "hook" on the HFSQL files, causing an exclusive access error when you try to restart.
Anti-Virus and Indexing ExclusionsWindows Indexing or aggressive Anti-Virus real-time scanning can "grab" a file the microsecond it is created or modified. To prevent this, add your data folder (.fic, .mmo, .ndx) to the exclusion list of your security software. Pro-Tip: The HErrorExclusive() Function
In WinDev 25, you can manage these errors gracefully instead of letting the application crash with a "Dump." Use HOnError or check the error code after an open attempt:
IF NOT HOpen(MyFile) THEN IF HErrorExclusive() THEN Error("The file is currently locked by another user. Please try again later.") ELSE Error(HErrorInfo()) END END Use code with caution. Copied to clipboard
By handling the conflict in the code, you replace a frustrating system crash with a helpful message for your users.
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:
Understanding WinDev
Before you start, ensure you have a solid understanding of what WinDev is. WinDev is a development environment that allows for the rapid creation of Windows, Web, and mobile applications. Its strength lies in its ease of use and the speed at which applications can be developed.
The Mechanics (Behind the Scenes)
- Lock Acquisition: WinDev 25 sends a lock request to the HFSQL server (or local driver). If any other process currently holds a read or write lock, the dump will fail immediately or wait (depending on the
hWaitparameter). - Blocking I/O: Once the exclusive lock is granted, all other connections—including
HRead,HReadFirst,HAdd,HModify, andHDelete—are blocked. The users see the application "hang" or receive a "File locked by another application" error unless your code handles this gracefully. - Consistent Snapshot: The engine then dumps the file byte-for-byte. Because no changes can occur, the resulting backup is 100% transactionally consistent.
- Lock Release: Immediately after the last byte is copied, the exclusive lock is released, and normal operations resume.
Strengths
- Rapid development: WinDev’s high-level language (WLanguage) and visual designers make building standard business apps very fast compared to glueing frameworks together.
- All-in-one IDE: Built-in database tools, report designers, and deployment utilities reduce the need for third-party tools.
- Strong legacy support: Mature environment with many prebuilt components and a community of long-time users; good for maintaining or modernizing existing WinDev applications.
- Productivity features: Code generation, template libraries, and integrated testing/debugging increase developer throughput.
Conclusion
WinDev 25 reinforces PC SOFT’s vision of a unified, productivity-first development environment tailored to business applications. It delivers meaningful tooling and performance improvements that benefit teams prioritizing speed and integrated features, while trade-offs—especially around ecosystem lock-in and licensing—should be carefully weighed against organizational goals.

In WINDEV 25, developers use dump files (typically with a .wdump extension) to capture the state of an application at a specific moment, such as during a crash or a specific runtime event.
dbgSaveDebugDump Function: This WLanguage function is used to programmatically save a dump of the application.
Analysis: To read these files, you can drag and drop them into the WINDEV editor to view the call stack and variable contents at the time of the dump.
Exclusive Mode: Debugging certain low-level operations or capturing specific system states may occasionally require the application to be in a suspended or "exclusive" state to ensure data consistency in the dump. 2. HFSQL Database "Dump" and Exclusive Access
In the context of HFSQL (the database engine used by WINDEV), a "dump" often refers to a backup or an export of data files.
Exclusive Lock Requirements: Many critical maintenance operations in version 25—such as reindexing, certain backups, or restoring from a dump—require an exclusive lock on the .fic (data) and .ndx (index) files.
Conflict Resolution: If an application or user is currently accessing the database, WINDEV will throw an error indicating that "Exclusive Access" is required but cannot be obtained.
Troubleshooting: To resolve exclusive access conflicts during a dump or restore, ensure all client connections are closed via the HFSQL Control Center before initiating the operation. 3. Version 25 Exclusive Features
WINDEV 25 introduced over 900 new features, some of which are marketed as "exclusive" to certain license types or subscription models.
Smart Controls: New UI elements available starting in version 25.
Enhanced Analysis: Improved "super magnetism" in the data model editor for better alignment of analysis graphs. dbgSaveDebugDump (Function) - PC SOFT
Understanding and Resolving "Exclusive Dump" Errors in WinDev 25
If you are a WinDev developer, encountering a dump—the environment's term for a critical runtime error—is part of the job. However, errors involving Exclusive Access (often seen as "Error 70003" or related to hOpenExclusive) are particularly frustrating because they halt data operations entirely.
In WinDev 25, these errors typically occur when the HyperFileSQL (HFSQL) engine attempts to perform an operation that requires total control over a data file while another process still has it open. What Causes a "Dump Exclusive" in WinDev 25?
At its core, an exclusive dump happens when there is a conflict between shared access and locked access. WinDev 25 uses these locks to ensure data integrity during sensitive operations. Common triggers include:
Index Rebuilding (hIndex): You cannot rebuild an index while users are connected to the file.
Modification of File Structure: If you use hModifyStructure, the engine requires an exclusive lock to rearrange the physical .fic and .ndx files.
Optimization Tasks: Operations like hOptimize require the file to be closed to all other instances.
Ghost Connections: Sometimes, a previous debug session or a crashed client leaves a "zombie" connection on the HFSQL Client/Server engine. How to Troubleshoot and Fix the Error 1. Identify the Locking Process
Before you can fix the dump, you need to know who is holding the key.
For Classic HFSQL: Check for .lck files in the data directory. If the application isn't running, delete these manually.
For Client/Server: Use the HFSQL Control Center (Manta). Navigate to the "Connected Users" tab and see if there is an active session locking the table. You can manually "Disconnect" the user to free the file. 2. Implementation of hClose
A common mistake in WinDev 25 coding is forgetting to explicitly close a file before calling an exclusive function.
// Wrong way: Calling optimization while the file is linked to a table hOptimize(MyTable) // This may trigger an exclusive dump // Correct way: hClose(MyTable) hIndex(MyTable, hStable) Use code with caution. 3. Use hOpenExclusive with Caution
If your code explicitly calls hOpenExclusive, ensure you have a robust error-handling routine. If the function returns False, use HErrorInfo() to determine if the lock is held by another user. 4. Handling the "WLanguage Dump" Window
WinDev 25 provides a detailed dump window when these crashes occur. Look specifically for: The System Error Code: Often 5 (Access Denied).
The Logic: Is the dump happening during a TableDisplay or a background Thread? Often, a background thread is trying to read data while the main thread is trying to perform an exclusive maintenance task. Best Practices to Avoid Exclusive Errors
Maintenance Mode: Build a "Maintenance Flag" into your database. Before performing index repairs or structure updates, have the application check this flag and prevent users from logging in.
Transaction Management: While transactions handle data integrity, they can occasionally cause locks that look like exclusive errors if they aren't validated (hTransactionEnd) or cancelled (hTransactionCancel) properly.
Update HFSQL Engine: WinDev 25 had several updates during its lifecycle. Ensure your HFSQL Client/Server engine version matches or exceeds your framework version to avoid known locking bugs. Conclusion
A "WinDev 25 dump exclusive" error is almost always a sign of a concurrency conflict. By monitoring your connections through the HFSQL Control Center and ensuring your maintenance code properly closes files before requesting exclusive access, you can eliminate these crashes and provide a smoother experience for your end users.

WinDev 25 uses a proprietary database engine called HFSQL (HyperFileSQL). When users discuss a "dump exclusive," they are usually referring to creating a backup or a data export while the database is in "Exclusive Mode." This mode ensures data integrity by preventing other users or processes from modifying records during the operation.
Below is a technical overview of how to manage exclusive access and perform data dumps in WinDev 25. 🔒 Understanding Exclusive Mode
In WinDev, exclusive access is required for structural changes or full data consistency during exports. HReadState: Used to check if a file is already locked.
HExtendedLock: Can be used to secure specific records or files.
HClose: Often necessary to close existing connections before reopening in exclusive mode.
Error Handling: You must handle Error 70003 (File already in use) when attempting to gain exclusive access. 🛠 Methods for Creating a Data Dump 1. HFSQL Control Center (Manual) The most direct way to perform a dump in WinDev 25: Open the HFSQL Control Center. Connect to your server. Right-click the database or specific table. Select Maintenance > Backup.
Choose the "Full" option to ensure a complete dump of the structure and data. 2. Programmatic Export (WLanguage)
If you need to trigger a "dump" via code, use the HExportXML or HExportJSON functions. To ensure it is "exclusive," wrap it in a management block:
// Attempt to open the file exclusively IF HOpen(MyTable, hReadOnly + hKeepError) = False THEN // Handle the case where the file is in use Error("Database is currently busy. Exclusive dump failed.") ELSE // Perform the dump to a text file HExportXML(MyTable, "C:\Backups\MyDump.xml") HClose(MyTable) END Use code with caution. Copied to clipboard ⚠️ Security and Integrity Warnings
Runtime Conflicts: Forcing an exclusive lock will kick out active users. In a production environment, this can lead to data loss for the end-user if not handled via a "Log-off" notification system.
Index Files: Ensure your dump includes .ndx (index) and .ftx (full-text) files if you are doing a file-level copy, though using HFSQL tools is safer.
Client/Server vs. Classic: In Client/Server mode, use the HBackup function. It allows for scheduled "snapshots" which are the professional equivalent of a manual dump.
💡 Note on Reverse Engineering: If your search for "dump exclusive" relates to bypassing security or extracting data from compiled .exe or .wdl files, please be aware that WinDev uses encryption for its libraries. Attempting to dump memory to bypass "exclusive" hardware keys (dongles) is a violation of the PC SOFT End User License Agreement (EULA). To provide more specific help, could you clarify: Are you trying to automate a backup for a live application?
Are you dealing with a corrupted file that won't open except in exclusive mode?
Are you using Classic HFSQL (local files) or HFSQL Client/Server?
