Hi

I have received an error message from a user of my software, which is an
Add-In for Visual Studio 2005. The user is using a French version of Visual
Studio.

A BadImageFormatException occurs, and it appears that the FileName property
in the BadImageFormatException structure is an empty string.

The stack trace is as follows:

   à System.ModuleHandle._GetPEKind(Int32& peKind, Int32& machine)
   à System.ModuleHandle.GetPEKind(PortableExecutableKinds& peKind,
ImageFileMachine& machine)
   à System.Reflection.Module.GetPEKind(PortableExecutableKinds& peKind,
ImageFileMachine& machine)
   à System.Reflection.Assembly.ComputeProcArchIndex()
   à System.Reflection.Assembly.GetName(Boolean copiedName)
   à System.Reflection.Assembly.GetName()
   à
System.ComponentModel.Design.RuntimeLicenseContext.CaseInsensitiveManifestResourceStreamLookup(Assembly
satellite, String name)
   à
System.ComponentModel.Design.RuntimeLicenseContext.GetSavedLicenseKey(Type
type, Assembly resourceAssembly)
   à
System.ComponentModel.LicenseManager.LicenseInteropHelper.GetCurrentContextInfo(Int32&
fDesignTime, IntPtr& bstrKey, RuntimeTypeHandle rth)
   à MultiLang.modGlobalDbUtil.OpenGlobalDatabaseConnection()
   à MultiLang.ctlToolWindow.InitAddInWindow(DTE newVal)
   à MultiLang.Connect.OnConnection(Object application, ext_ConnectMode
connectMode, Object addInInst, Array& custom)

The last function in my software is
MultiLang.modGlobalDbUtil.OpenGlobalDatabaseConnection
which opens an ADO database connection to an mdb (access 2000) database
file.

This is ADO and not ADO.NET.

I have simply no idea why execution is entering LicenseManager code. I have
tried putting a breakpoint in this module (via the disassembly window) but
as far as I can tell it is not entered on my system.

I am totally baffled by this error and would appreciate any help.

Thanks in advance,
Phil

What I wrote before was not quite correct. I have now succeeded in setting
breakpoints in the lower level functions and have got the slightly more
detailed stack trace, listed below.

In addition, I can now see that this senario occurs on creating an ADO
connection object, specifically in the first of three call instructions
generated, although I don't know what these specific calls do.

gdb = New ADODB.Connection
        00000145 mov ecx,5FB6DBCh
  --->  0000014a call 740C9DA4
        0000014f mov dword ptr [ebp-64h],eax

        00000155 call 001F2FD8
        0000015a mov eax,dword ptr [ebp-64h]
        0000015d lea edx,ds:[02507754h]
        00000163 call 740AF630


I am still unfortunately non the wiser about how to help my user.
