If you are trying to "dump" or export data and encounter this, you can test for the lock in your code:
: Classic networks relying on Windows file sharing are highly prone to exclusive dump errors due to network drops. HFSQL Client/Server manages locks in memory, drastically reducing lock-related crashes.
// Backup entire database with exclusive locks on all files HBackupDatabase("C:\MyAppData\", "C:\Backups\FullBackup_" + DateToString(Today()) + ".wdb", hExclusive + hForceFileLock) windev 25 dump exclusive
In the ecosystem of WinDev 25, data is king. Whether you are managing a local shop management system or a complex corporate ERP, the integrity of your HyperFileSQL (HFSQL) database is non-negotiable. Among the myriad of control commands and backup procedures available to developers, one phrase stands out for its power and potential peril:
| Feature | Standard Dump (Non-Exclusive) | Dump Exclusive (Windev 25) | | :--- | :--- | :--- | | | Fully available (reads & writes) | Completely unavailable until dump finishes | | Consistency Guarantee | Possible logical inconsistency (dirty reads) | Guaranteed consistent snapshot | | Backup Duration | Fast; no waiting for locks | May be slower, plus lock acquisition time | | Risk of Deadlocks | Low | High (if not managed with timeouts) | | Recovery Reliability | Moderate (may require transaction logs) | High (can restore as-is) | | Ideal Use Case | Low-traffic times, non-critical tables | Midnight backups of financial/accounting tables | If you are trying to "dump" or export
It is crucial to understand the legal framework surrounding WinDEV. PC SOFT's licenses are explicit and legally binding. The standard license agreement states that the software is the "sole and exclusive property of PC SOFT" and that the customer has only acquired the right to use the software under specific terms.
Keep in mind that this is not an exhaustive list, and WinDev 25 may offer more features and functionalities beyond what's mentioned here. Whether you are managing a local shop management
The updated UI/UX caters to both novices and experts:
A dump file ( .wdump ) in WINDEV is a snapshot of an application's state at a specific moment in time. When an error occurs, or when a developer explicitly triggers a dump, WINDEV captures: The call stack (how the program reached that point).
A memory dump (or .dmp file) is a snapshot of an application's volatile memory at a specific moment in time, usually right when a fatal error occurs. In WinDev 25, these dumps capture the state of the HFSQL database engine, the call stack of the execution thread, and the values of local and global variables.
