About Problem in Thread Local Storage(TLS) with DLL

NTDEV
1

Hello,
I am using the dll with TLS Section and Tls Table Entry in Data
Directory of that dll.I have converted the exe(TLS) into dll and using
that dll(just changed the dll flag and address entry point). But when i
use the function of that dll it crashes after successfully loading the dll
with loadlibrary. I think that the entry in Tls Table Entry in Data
Directory is created from Borland compiler.

I have used the .tls section of dll which is generated by Microsoft
compiler which does not give problem.

The problem is caused when uwing the dll with tls section.

if any one knows about the loader and the way loader works will dll
with tls section or anything replated to this plz post reply.

-Tom

DLLs which have the .tls section cannot be loaded by LoadLibrary, they can
only be loaded during initial import resolution at EXE load.

This is documented IIRC.
