Hi!
First of all, thanks for this tip, it really helped me a step for.
Now, i have downloaded the Sources of Xerces to recompile them and get a
debug able DLL of it and i think, i have found the bug.
The Byte Alignment of Xerces is 8 Byte, but for reall beeing
"Cross-Plattform", it would have to be 4 Bytes, so that Xerces would be able
to export all function "as is" and can be called from Delphi and so on.
Is there a 4 Byte compiled Version?
I cannot compile it, because i am missing the "afxres.h" File!
Any help would be great...
BESTe Gr�sse, BEST regards

|# It's hard to say what the problem is without more details.
|# What is the
|# exception it throws? Is this only under the debugger? Xerces does
|# throw
|# exceptions internally. Perhaps Delphi's debugger is showing these
|# internal
|# exceptions.
|#
|# [sp]>: No, the Exeptions are throws in the IDE and when i
|# run the linked
|# Delphi Programm (.exe).
|#
|# Are you sure you are declaring the C++ function with the
|# same calling
|# convention in Delphi and C++ (cdecl, stdcall, etc..)?
|#
|# [sp]>: Yes i do. We have many DLL�s here, made with VC++
|# and then called
|# them by Delphi. So i am sure i have made everything right.
|# Even: I made 4
|# other Developers crazy for searching the Bug in my Code :)
|#
|# Your sample console program (written in C++?) which works
|# calls the same
|#
|# DLL that the Delphi program is calling?
|#
|# [sp]>: Yes, absolutely. There are no changes made in the
|# DLL, i simply
|# copy&pasted it!
|#
|# Your C++ function should make sure that no exceptions are
|# thrown out of
|# the
|# function since Delphi probably wouldn't be able to handle them
|# correctly. You should wrap the everything in your C++
|# function in one
|# try/catch block to make sure no exceptions are thrown out
|# of the DLL.
|# try { /* Xerces calls */ }
|# catch(...) { /* signal error condition by some other means */ }
|#
|# [sp]>: I have a construct like this. But my main Problem
|# is, that Delphi
|# even fails to step over the LoadLibrary Line (error code: 998
|# ERROR_NOACCESS). The Lib is there, thats not the point. I
|# tryed it, when i
|# removed the Xerces DLL�s from my Directory and it throws me
|# an execption
|# like "dll xerces_xyz.dll not found". When i put them in, my
|# mashine do
|# something on my harddisk and then throws this exeption in
|# LoadLibrary. In my
|# Code from VC++, there is a try...catch in it, when running
|# into the 'catch'
|# part, it only gives back a int-returncode!
|# I try to solve this for 4 Days, but all i get till now are
|# more white hairs
|# ;) So, it is very nice of you to help me, thank you, and i
|# hope, it will
|# work next week.
|#
|# [sp]>: P.S. Sorry for my terrible englisch :)
