Windev stores forms, images, and reports as custom resources.
Tool:reshacker, ResourceHacker, or custom Python with win32api.
Example (Python with pefile):
import pefile
pe = pefile.PE("app.exe")
for rt in pe.DIRECTORY_ENTRY_RESOURCE.entries:
print(hex(rt.struct.Id))
Limitation: Forms are not stored as standard .dfm (Delphi) or .resx; they are a proprietary binary format. Dumping gives raw data, not a reconstructable source.
A client’s Windev 27 app would vanish when clicking a certain report button – no error dialog, no Windows Event Log entry.
Without the dump, that would have been hours of guesswork.
# wd27_dump_parser.py
import sys
import pefile
def extract_wd27_sections(dump_path):
pe = pefile.PE(data=open(dump_path, 'rb').read())
for section in pe.sections:
if b'WD27' in section.get_data():
print(f"Found WD27 section at hex(section.VirtualAddress)")
with open("wd27_extracted.bin", "wb") as f:
f.write(section.get_data())
# Also scan raw dump for magic
with open(dump_path, 'rb') as f:
data = f.read()
idx = data.find(b'WD27')
if idx != -1:
print(f"Magic found at offset hex(idx)")
# Extract next 1MB
with open("wd27_magic_dump.bin", "wb") as out:
out.write(data[idx:idx+0x100000])
if name == "main":
extract_wd27_sections(sys.argv[1])
Run the WinDev 27 application. Use Process Hacker to locate the main executable and loaded WD270.DLL.
tasklist /m wd270*.dll
Example output:
MyApp.exe 1234 WD270.DLL, WD270HF.DLL
“Dumping Windev 27” is technically feasible for:
However, full source recovery is impossible due to the native compilation model. If you need to recover lost source code, contact PC SOFT or restore from backups — dumping will not reproduce .wdw/.wda/.wdm files.
Would you like a sample Python script to extract human-readable strings from a Windev 27 memory dump?
Windev 27 is a powerful rapid application development (RAD) system published by PC SOFT. It is widely used to create Windows applications—from small utilities to complex enterprise resource planning (ERP) systems. However, developers and technical analysts often encounter a scenario where they need to dump Windev 27 data. “Dumping” can refer to three distinct but related operations:
This article walks you through each method step-by-step, explains the tools required, and highlights key precautions when dealing with Windev 27’s proprietary structure.
