Field token out of range (System.BadImageFormatException)

[Guest]

I've converted a VB6 project to VB.Net 2005. (Actually using vstudio pro
2005).
I'm on a machine that also has VB6 and Vstudio.net 2003 on it. The project
uses Word, Excel, MapPoint and SqlClient (database is SqlServer 2000). OS is
WinXP SP2.

When I run the project, it opens the MDI form (MdiMain.vb) fine, but when I
open one of the child forms and try to select something in a combo box
(cboFilter2) it stops on a line of the MdiMain.Designer.vb file. The line it
stops on is the very first statement:
<Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated()>
Partial Class MdiMain

I've copied the stack trace below: It's long and ugly! I haven't been able
to find any information on this "Field token out of range" error. Anyone
have any good ideas as to where I should start looking?

System.BadImageFormatException was unhandled
Message="Field token out of range."

You are reading the stack trace upside-down.

The place to start looking is the
JWFLTerritory.frmList.cboFilter2_SelectedIndexChanged event handler.

.... and the key word you are looking for in help is BadImageFormatException.

I also notice that the MapPoint 11.0 Object Library is actually a .TLB
instead of a DLL, and unlike the Word or Office Object Libraries, MapPoint
gets Referenced with "Copy Local" = true. Does this bring to mind any
possible causes of the error below?

Sorry it took awhile to reply. This is a "volunteer" project, so it doesn't
get the highest priority.

I've tried looking for both "BadImageFormatException" and "Field Token out
of range". Neither of which yielded any useful information.
How can I figure out what "Image" it's trying to load? Why would it be in
MdiMain.Designer.vb:line 2 (code it wrote for itself) when it's already been
through there before. I've stepped through this code when the program
started, and it made it through fine. I haven't unloaded the main form, and
yet now I'm doing something on the child form (selecting an item in a combo
box) and the program stops back in MdiMain.Designer.vb. I'm not reading the
stack trace upside-down: it really is stopping in debug mode with the
execution point is on this line in the MDI form's designer module:
<Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated()>
Partial Class MdiMain
How can that happen?
