Windev 25: Dump Exclusive

Here is the core definition every WinDev 25 developer must memorize:

"Dump exclusive" is a backup mode where WinDev 25 locks the entire database file (or the whole database) for the duration of the dump, preventing any other user or process from reading or writing to it.

When you check the "Exclusive" option in the HDump function or the HFSQL Control Center, you are instructing the HFSQL engine to acquire an exclusive lock on the data file.

WinDev 25 (released ~2018) may not have an explicit "exclusive dump" menu item. In that case:

WINDEV 25 introduces several groundbreaking features:

WINDEV 25 is a compelling choice for enterprises needing a hybrid low-code platform that balances rapid prototyping with high customization. Its AI integrations and cloud-native tools position it as a future-proof solution, particularly for Windows-centric workflows. However, smaller teams or startups might explore free alternatives like OpenEdge or open-source frameworks if budget constraints apply.

Verdict: A solid upgrade for developers seeking efficiency, cross-platform flexibility, and enterprise-grade scalability. For those entrenched in Microsoft ecosystems, WINDEV 25 is a strategic investment.

Note: For the most accurate details, refer to PC SOFT’s official documentation or their 2024 roadmap updates.

Final Rating: ★★★★☆ (4.5/5) – A powerful platform with minor room for UI refinement and template diversity.

To harness the power of exclusive dumps without destroying user experience, follow these enterprise-grade best practices.

To illustrate why "dump exclusive" is both a savior and a burden, let’s look at a comparative table:

The golden rule: Use dump exclusive for critical financial, inventory, or transactional data. Use standard dump for static lookup tables or logs.

In the context of WinDev 25, a "dump exclusive" generally refers to a specific error or state where the application cannot access a data file (.fic) because it is being held exclusively by another process or task. This is common in HFSQL (HyperFileSQL) environments. Understanding the "Exclusive" Lock in WinDev 25

When WinDev or an HFSQL engine attempts to perform a structural change (like a HModifyStructure) or a maintenance task (like HIndex), it requires exclusive access. This means no other users or applications can have the file open, even in read-only mode. Common Causes

Active User Sessions: Another user is currently running the application and has the file open. windev 25 dump exclusive

Ghost Processes: The application crashed previously, but the WDTST.EXE or the runtime process is still hanging in the background, keeping a handle on the file.

Backup/Antivirus Software: A backup routine or an antivirus scan is currently locking the .fic, .mmo, or .ndx files.

HFSQL Control Center: You might have the file open for data viewing in the HFSQL Control Center while trying to compile or update the structure in the IDE. How to Resolve it

Check for Ghost Processes: Open Task Manager and kill any remaining instances of your application or WinDev runtime processes.

Disconnect Users: If using HFSQL Client/Server, use the HFSQL Control Center to view active connections and manually disconnect them.

HDisconnect: Ensure your code explicitly calls HDisconnect() or HClose("*") before attempting operations that require exclusive rights.

Manage Lock Files: Check the data directory for .lck files. While HFSQL usually manages these, a persistent lock file after a crash might need manual deletion (ensure the engine is stopped first). Programmatic Handling

If you are trying to "dump" or export data and encounter this, you can test for the lock in your code:

IF HListProcess(MyConnection) <> "" THEN Error("Exclusive access denied: Other users are connected.") RETURN END Use code with caution. Copied to clipboard

In WinDev 25, an "exclusive dump" typically refers to creating a backup of an HFSQL database that requires all user connections to be closed to prevent file locking. Alternatively, it may involve generating a memory dump to diagnose an exclusive access violation during an application crash, with improved debugging features introduced in version 25.

Understanding the "Dump Exclusive" error in WinDev 25 is essential for maintaining stable database environments. This error typically occurs when the HFSQL engine attempts to perform a maintenance task—such as an index rebuild or a structure update—but cannot gain total control over the data files because another user or process is still connected. What is a Dump Exclusive?

In the context of WinDev, a "Dump" usually refers to the backup or export of a database structure and its data. An "Exclusive" lock means the system requires 100% of the access rights to the files. If even one client application has a .fic or .ndx file open, the HFSQL engine will throw an error because it cannot safely modify or move the files while they are in use. Common Causes of the Error

Active User Sessions: A teammate or client left the application running on their workstation. "Dump exclusive" is a backup mode where WinDev

Ghost Connections: The application crashed, but the HFSQL Client/Server engine still thinks the user is "connected."

Background Tasks: Scheduled backups or automated reporting tools are accessing the database.

File System Locks: Antivirus software or Windows indexing services are scanning the data folder. Step-by-Step Troubleshooting 1. Use the HFSQL Control Center

The fastest way to resolve an exclusive lock issue is through the HFSQL Control Center (CC HFSQL): Connect to your server. Go to the "Connections" tab. Identify any active users.

Right-click and select "Disconnect the user" (be careful, as this may cause unsaved data loss for that user). 2. Implement "HDisconnect" in Code

To prevent this error in production, your WinDev 25 code should handle disconnects gracefully. Use the HDisconnect function to ensure that when a user closes a window or the app, the server-side socket is properly released. 3. Check for Zombie Processes

Sometimes the WinDev IDE or the WX25 runtime hangs in the background. Open Task Manager (Ctrl+Shift+Esc).

Search for any processes named WDMylocal.exe or your project’s executable name. End Task on any lingering instances. Best Practices for WinDev 25 Database Maintenance

To avoid "Dump Exclusive" errors in the future, follow these architectural tips:

Soft Close Procedures: Build a "Force Close" mechanism into your app. This can be a simple timer that checks a specific record in a Param table; if you flip a "Maintenance" switch to true, the app notifies users to save and then closes itself.

Scheduled Downtime: Perform database dumps and re-indexes during off-peak hours using the HFSQL Service Task Scheduler.

Snapshot Backups: If using a Virtual Machine, take a snapshot or use "Hot Backups" (HBackup), which allow for data copying without requiring exclusive locks, though they have limitations compared to a full structural dump. Advanced Recovery: Handling Corrupt Indexes

If the "Dump Exclusive" error persists even when no one is connected, your .ndx (index) files might be flagged as "in use" by the operating system due to a previous crash. Stop the HFSQL Service. Delete the .lck (lock) files in the data directory. Restart the service and attempt the dump again.

Write a code snippet for an automated "Kick-off" utility for users.

Compare Hot Backup vs. Cold Dump performance for large datasets.
