CCW and 0x80131522

[Colin Desmond]

We have written a COM wrapper around the FlexGrid control called GridControl.
It is written using ATL and completely unmanaged C++. It uses ADO Recordsets
for its interaction with clients.

We now want to include it into a C++/CLI application. We have code which
uses #import "GridControl.dll" to gain access to it. This worked well when
our application was just a C++ one, but now it has /clr switched we get the
following error at startup (very very early in the process)

An unhandled exception of type 'System.IO.FileLoadException' occurred in
Unknown Module.

Additional information: Could not load file or assembly 'OurApplicationName,
Version=1.0.2207.30381, Culture=neutral, PublicKeyToken=f456eafc1bd82344' or
one of its dependencies. Could not find or load a type. (Exception from
HRESULT: 0x80131522)

I have created a CCW using TBLIMP for the GridControl and signed it ike this:

tlbimp /publickey:GridControl_PublicKey.snk /delaysign
...\bin\GridControl.dll /out:Interop.GridControlLib.1.0.dll
sn -Vr Interop.GridControlLib.1.0.dll
copy "$(ProjectDir)Interop.GridControlLib.1.0.dll" "..\bin\"
gacutil /i ..\bin\Interop.GridControlLib.1.0.dll

I have added a refernece to the CCW to the applicaiton (by browsing, did not
appear in the .Net list) and when it builds it takes a copy of this file
into its debug folder.

I just can't get it to run. I have tried copying all the files into a single
folder (including the ADODB PIA) but something is not right.

Any suggestions?
Thanks

Colin

I am getting the same error in a slightly different context and, using
google, this is the only post I could find with the same exact
problem.

If anyone has any information it would greatly be appreciated. I've
tried even recreating the entire solution and all projects in it
(instead of upgrading from VS 2003 to VS 2005) to no avail.

I have an MFC project built with \CLR:oldSyntax and am using an
assembly written in C#. I have the code so it is as a project in my
solution and referenced as such. I also get the exception early in the
application's startup. All of my native DLLs load fine but then this is
thrown shortly after mscorlib is loaded. After mscorlib there is this:

'ourapp.exe': Loaded 'C:\WINDOWS\system32\uxtheme.dll', No symbols
loaded.
'ourapp.exe': Loaded 'C:\WINDOWS\system32\msctf.dll', No symbols
loaded.

The program '[3636] ourapp.exe: Managed' has exited with code 0 (0x0).
The program '[3636] ourapp.exe: Native' has exited with code 0 (0x0).

Does this help any?

Brian,

There is a resolution to this problem, but you won't like it! It turns out
to be related to a hard limit in .Net regarding the number of symbols in an
assembly. Take a look at my other post called "Message: Internal limitations:
too many fields" for a brief discussion of the problem.

Crap. Well, thanks Colin. I'll take a look and see if it's the same
problem.
