Dump Windev 27 (2027)

WinDev projects rely on a complex set of files. Here is a dump of the extensions you will see:

Windev compiles to native Windows executables, but its runtime and proprietary libraries can obscure what’s really happening. Common dump-worthy scenarios:

A dump gives you a snapshot of memory, loaded modules, threads, and heap allocations at a specific moment.

Automate dump creation on specific conditions: dump windev 27

procdump -ma -e 1 -h MyWindevApp.exe windev_crash.dmp

PC SOFT provides HFSQL Control Center (free with Windev 27). To dump a database:

Limitation: Requires the original database structure. If the .WDD (analysis file) is missing, HFSQL Control Center will fail.

Dumping does NOT give back original .win or .wdm files. You get: WinDev projects rely on a complex set of files

| Recoverable | Not Recoverable | |-------------|----------------| | All string literals | Variable names (unless debug symbols) | | Window/control layouts | Original comments | | Event handlers (p-code) | Project structure | | HyperFile queries | Compilation settings |

You can rebuild a readable version by writing a p-code disassembler. WinDev opcodes (v27) are documented partially in reversing forums (e.g., 0x01 = ADD, 0x02 = SUB, 0x10 = CALL, 0x1A = PUSH_STRING).

The syntax is similar to BASIC/Pascal.

Variables:

// Simple types
sName is string = "John"
nAge is int = 30
bActive is boolean = True
rPrice is real = 19.99
// Arrays
arrNames is array of strings
ArrayAdd(arrNames, "Alice")
// Structures
STCustomer is Structure
    Name is string
    ID is int
END

Database Access (HFSQL):

// Declaration
HDeclare("Customer", "Name, ID")
// Reading
HReadFirst(Customer, Name)
WHILE NOT HOut(Customer)
    Trace(Customer.Name)
    HReadNext(Customer, Name)
END
// Query
HExecuteSQLQuery("SELECT * FROM Customer WHERE ID > 10")

UI Controls:

// Setting a value
EDT_Input1 = "Hello World"
// Events (Typically in the "Initialization" or "Click" events of the code editor)
// Example: Button Click
Info("Button Clicked")
