Windev 25 Dump Exclusive

Utilize HFSQL transactions ( HTransactionStart / HTransactionEnd ) to manage locks efficiently without requiring total file exclusion.

The most frequent culprit is a simple programming oversight. A user fetches a record using HReadFirst or HReadSeekFirst with a write lock ( hLockWrite ), performs an operation, but the application never calls HUnlockRec or moves off the record. 2. Ghost Connections on HFSQL Server

You cannot open a dump file in WINDEV 25 if it was built with an older or newer version.

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

Full exclusive dumps contain raw RAM contents, which might include sensitive user data or unencrypted string variables. Use exceptionDumpMini unless a deep heap analysis is strictly required.

To get the most out of Dump Exclusive, follow these best practices:

In the world of WinDEV, a "dump" is a file that records a detailed view of your application's data at a specific point in time. The keyword exclusive can be interpreted in two primary ways: In previous versions, exporting a database with millions

Ensure that secondary threads in your WinDev 25 application use separate database contexts to prevent self-locking. To help troubleshoot this further, please share:

// Bad Practice: Leaves potential lingering locks if an error occurs HReadSeekFirst(CUSTOMER, IDCUSTOMER, 125, hLockWrite) IF HTFound(CUSTOMER) THEN CUSTOMER.Status = "Active" HModify(CUSTOMER) // Missing HUnlockRec! END // Good Practice: Use automatic context or explicit unlocking HReadSeekFirst(CUSTOMER, IDCUSTOMER, 125, hLockWrite) IF HTFound(CUSTOMER) THEN CUSTOMER.Status = "Active" HModify(CUSTOMER) HUnlockRec(CUSTOMER) // Explicitly free the record END Use code with caution. 2. Use HSetTimeout to Prevent Immediate Crashes

Every year, the WinDev community eagerly awaits the new version. But this year, the "Dump" isn't just a figure of speech for a data export—it’s the internal codename for the massive architectural overhaul regarding . an open connection

You have 200,000 ledger entries and 5,000 account records. You need to freeze everything.

The error triggers because the engine detects an active token, an open connection, or an unreleased lock on the target file. Even if no real users are logged in, background tasks or ghost sessions might still hold the file. Step-by-Step Resolution Strategies 1. Identify and Disconnect Active Sessions

Any active transaction attempting to write during the dump will fail with an error message like: "File locked by another application. HFSQL error code: [xxx]" . Without proper error handling, this leads to data loss for the end user.

To maximize the utility of exclusive dumps without impacting user experience or violating privacy laws, implement these production strategies:

Allow multiple users to read a record or file simultaneously.
