Sorry, I made a mistake. I've updated the title ..
To summarize:
1. I can load the DLL compiled with cygwin with LoadLibraryA,
but not remotely with CreateRemoteThread.
2. The same DLL compiled with msvc works with both LoadLibraryA and
CreateRemoteThread
Answer to Joost:
constructor and destructor are called with LoadLibraryA, but not with
CreateRemoteThread either
Answer to Marco
1. I can't use mingw, it does not provide sys/XXX.h, e,g socket
2. I copied cygwin1.dll to system32, and it works outside cygwin environment
Here's a implementation of the DLL injector in C#:
