Never run an exclusive dump programmatically without checking the time.
// Only run exclusive dump between 2 AM and 4 AM
IF Hour(CurrentTime()) BETWEEN 2 AND 4 THEN
HDump("INVOICE", "Backup.wdb", hExclusive)
ELSE
// Use standard dump or skip
HDump("INVOICE", "Backup.wdb")
END
The most exciting part of this exclusive look is the new WD-AI Migrator. Included in the WinDev 25 package is an analysis tool that scans your existing WinDev 24 projects and "dumps" a migration report.
It doesn't just tell you what breaks; it suggests fixes. It looks like PC Soft is leveraging LLM technology to understand your specific codebase, making the upgrade path smoother than the dreaded WinDev 23-to-24 transition. windev 25 dump exclusive
The updated UI/UX caters to both novices and experts:
A dump exclusive is worthless if you cannot restore it. Always test: The most exciting part of this exclusive look
// Restore a dump exclusive backup
IF HRestore("C:\Backups\Customer_Dump_2025.wdb", "C:\RestoreTest\", hForceRestore) THEN
Info("Restore successful. Verify integrity.")
END
Visually, the IDE (Integrated Development Environment) has received a facelift. While the ribbon interface remains, the "Dark Mode" is no longer a high-contrast hack—it is native and polished.
The code editor now supports "Code Lens" features, allowing you to see references and changes directly above your function declarations. No more right-clicking and searching for "Find All References." A dump exclusive is worthless if you cannot restore it
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.
Before we dissect the "exclusive" modifier, we must first understand what a DUMP does in the HFSQL world.
WinDev 25 uses HFSQL as its native database engine. When you perform a standard dump (non-exclusive), the HFSQL engine reads the data files (.FIC, .MMO, .NDX, etc.) and creates a backup archive (typically .WDB or .FIC backup files). During a standard dump, the database remains online. Reads are allowed, and in many cases, writes are temporarily queued or handled via transaction logs.
The problem with a standard dump:
If a user modifies a record while the dump is reading that specific page of the file, you risk a "dirty read" or an inconsistent snapshot. For example, a header record might be backed up before its corresponding line items are updated, leading to a referential integrity mismatch in the backup file.
