Hi,

We were testing out our application with FastCode patching of Move etc.

On a Windows 2003 Server Standard Edition with DEP enabled, it crashed at
startup.

After a little bit of trial and error and changing the elCodeHook code, I
found the solution.

1. The first VirtualProtect call should use PAGE_EXECUTE_READWRITE not
PAGE_READWRITE

2. The second VirtualProtect call should be removed

Also, to make debugging easier, I've un-commented the RaiseLastOSError;
calls in case the VirtualProtect calls fail.
And I moved unused members into the private section.

I've uploaded my version of elCodeHook to .attachments ("FastCode: Win64
DEP-safe version of elCodeHook").

It also includes an updated version of elGetRTLAddress. This unit only reads
from the code segment, so it shouldn't mess with VirtualProtect at all.

btw, is this the right procedure to contribute FastCode changes?

Hi Hallvard

Good.

This is a fine way to post your findings.

We must hope that the webmanager picks it up and makes a release.

Best regards
Dennis
