Shaikh,

Typically, you get a Bad Calling Convention error when arguments passed to
the DLL do not match the data type (long, integer, etc) or the reference
type (byval or byref) specified by the DLL.

Post your Declare statement and the code you are using to call the function.

Hello,
I have the following strange problem.
I have an excel program that uses a dll. Every thing is working fine
(still now) with my old laptop. But giving me error 49 - Bad DLL Calling
Convention (Error 49) - in my new laptop. Files and dll are same in both the
machine.

Both laptops have windows XP
Old laptop has Office XP (Office 2002) and new laptop has Office 2003

I am suspecting something wrong in Office 2003. Can anybody please tell me
whats the problem?

-Thanks.
