Hi,
we are finding some very strange behaviour in an ASP.NET application that
references a VB6 DLL. When the reference is created to the VB6 DLL, Visual
Studio generates an interop DLL for both our DLL and also for the VBA DLL
(Interop.VBA.dl l).
When we run our web application, periodically we obtain the following error
message:
Parser Error Message: Access is denied: 'Interop.VBA'.
Source Error:
Line 196: <add assembly="Syste m.EnterpriseSer vices, Version=1.0.500 0.0,
Culture=neutral , PublicKeyToken= b03f5f7f11d50a3 a"/>
Line 197: <add assembly="Syste m.Web.Mobile, Version=1.0.500 0.0,
Culture=neutral , PublicKeyToken= b03f5f7f11d50a3 a"/>
Line 198: <add assembly="*"/>
Line 199: </assemblies>
Line 200: </compilation>
Source File:
c:\windows\micr osoft.net\frame work\v1.1.4322\ Config\machine. config Line:
198
The bizarre thing is that then the problem seems to disappear on its own.
It's as if the application has temporarily lost its' reference and then
finds it again.
Has anyone encountered this before? Does anyone know what the reason for it
is?
Thanks for your help,

Just as an update, it seems that the problem occurs when there are multiple
VS.NET instances running on a PC, each loaded with a solution that
references Interop.VBA.dll . Even if we are only running 1 debug session, it
seems that VS.NET gets confused about where to find the DLL. It would be
interesting to hear any additional feedback from anyone that's seen this
and/or can explain it.

I have a Dot Net project that references a COM DLL called
"Crypto.dll," which is registered on my machine. I added the reference
via the "Add Reference" dialog in Visual Studio Dot Net, and I am
successfully accessing methods in this DLL in some of my classes.
"Interop.CRYPTOLib" is the name of the interop VS.NET created for me
when I added the reference.
Frequently, when I try to run my application, I get the error that

Hi,
I am new to this ASP.NET thing and while going very slow, I am learning.
Then I got a Configuration Error out of nowhere when I ran my project.
I do have Excel as reference (but I haven't been able to use it yet).
My project has been running just fine and I am sure I did something strange
to make this occur, but I have no idea what I did. So now, all the work I've
put into this, is gone. Well, I hope not.

I have an ASP.NET (VB.NET) application that calls all VB6 COM DLL via
Interop. The DLL uses functionality contained in a Custom OCX Control
(Also VB6) that in turn contains a standard TreeView control. The
Custom OCX is not used for visual purposes, but has some functionality
that we require (hence hosting an OCX in a DLL).
Everything worked fine until we installed the latest service pack for

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
