Hi Phnimx,

Thanks for your feedback!

Yes, I have received the reduced sample project from your developer Philip.
I can reproduce this error in it. I have discussed with one developer from
VC++ team internally, below is his comment:

"You've got serious problems here.

You're using MFC and old-syntax CLR. I'm not even sure that is supported.
In any case, it is a very tricky business. You've upgraded the project from
a previous version of VC. I suspect not all of the settings got upgraded
correctly. You're exporting an entire class instead of individual
functions. Again, this is very tricky and not usually a good idea. You're
not properly initializing the CRT for your DLL. And finally, as I mentioned
before, you aren't initializing MFC for your DLL. MFC needs to be in
control of the entry point for MFC-based DLLs, but this DLL is set to
/NOENTRY.

I suggest starting over. Use the VC 2005 wizard to create a new C++ MFC DLL
project, then follow the instructions from MSDN on how to make this work
with managed code (if you really need managed code for this project):

To compile an MFC executable or regular DLL with /clr:
1.     Open the Project Properties dialog by right clicking the project in
the Solution Explorer and selecting Properties.
2.     Expand the node next to Configuration Properties and select General.
In the right pane, under Project Defaults, set Common Language Runtime
support to Common Language Runtime Support (/clr).
From the same pane, make sure Use of MFC is set to Use MFC in a Shared DLL.
3.     Under Configuration Properties, expand the node next to C/C++ and
select General. Make sure Debug Information Format is set to Program
Database /Zi (not /ZI).
4.     Under Configuration Properties, select C/C++ and then Code
Generation. Make sure Runtime Library is set to one of Multi-threaded Debug
DLL (/MDd) or Multi-threaded DLL (/MD).

Then copy the existing code into the new project."

I have tried to remove "/NOENTRY" linker option in the "Linker"->"Command
Line", now the error disappears. You may give a try.

I have forwarded this solution to that developer and he added some further
comment below:

"Perhaps just removing /NOENTRY would work for now. But you might run into
problems with some of the other areas I mentioned. There isn't enough code
in that project to really be a problem, so I would fix the few little
syntax errors and upgrade to /clr."

Hope this helps.

Best regards,
Jeffrey Tan
