On [Date of crash] , the WinDev 25 application [App Name] encountered a fatal error, resulting in an unhandled exception and the generation of a memory dump file (.wdmp or system-generated .dmp). The dump was successfully verified as a valid crash dump corresponding to the application process at the time of failure.
Initial analysis confirms the crash was not caused by external system failure but by an internal execution error within the WinDev 25 runtime or application logic.
Use this if you are a developer who has analyzed a crash dump or exported a project database.
Title: [Solved] Analysis of WinDev 25 Memory Dump – Issue Verified Body: Hey everyone,
Just sharing a solution for a recurring crash we experienced after migrating to WinDev 25.
The Issue:
The application was crashing during the HExecuteQuery process. We generated a full memory dump (.dmp) via the WD debugger.
The Verification:
After analyzing the dump in WinDbg, we verified that the issue stemmed from a conflict with the new parallel execution threads in WD25. The stack trace pointed to an access violation in wd250vm.dll.
The Fix: We had to explicitly disable "Parallel HFSQL" in the project description (Project > Description > Advanced > HFSQL).
Hope this saves someone else a few hours of debugging!
WINDEV 25 operates primarily with the Hyper File 5 database. Unlike client-server SQL databases that rely on transaction logs, HF5 is a file-based system. While extremely fast for standalone and client-server setups (via HFSQL), it is susceptible to:
A standard backup copies the raw .FIC files. A dump, however, reads the logical content of the database and writes it to a new, clean file (usually .WDD or a text-based .TXT or .XML). The "verified" flag means that after writing the dump, WINDEV 25 performs a line-by-line or record-by-record comparison between the source and the dump, using a CRC (Cyclic Redundancy Check) or internal hash function to ensure 100% fidelity.
