=link= - Windev 25 Dump Exclusive

Often necessary to close existing connections before reopening in exclusive mode.

This is the primary function for creating a comprehensive debug dump. It saves a .wdump file containing the stack and the content of all variables at the moment the function is called. This is the most detailed and exclusive snapshot you can take of an application's state.

: Certain manual backup routines that lock tables to ensure point-in-time consistency. Root Causes of the Error

Leaked benchmarks suggest that WinDev 25 introduces a multi-threaded dumping mechanism for HFSQL. In previous versions, exporting a database with millions of records while the application was live could lock the UI or cause significant lag. windev 25 dump exclusive

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?

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

// Sample structure for exclusive operations WHEN EXCEPTION IN // Attempt the exclusive operation / dump HExtractDump() // Or your specific backup logic DO // Handle the exclusive lock failure Error("The database is currently locked by another process: ", ExceptionInfo(errMessage)) END Use code with caution. Best Practices to Prevent Exclusive Lock Failures This is the most detailed and exclusive snapshot

For minimal downtime, consider this hybrid strategy:

While dump generation has been available, the latest versions (around 2025/2026) have enhanced the "exclusive" nature of these tools, particularly for subscription users. 1. Enhanced Post-Mortem Debugging

Sometimes the lock isn't held by HFSQL, but by the Windows operating system itself (e.g., an antivirus scanner, a backup tool, or a frozen wamexe process).

: Analysis of the volume and complexity of your code.

Wrap your dump and modification code in exception-handling blocks. This prevents the application from crashing and allows it to retry the operation.
