Problem calling a function in DLL

[Kedar]

Hi all,

I am facing a problem while making a call to a function in a DLL. I am
migrating my project from version 5. This same exact code used to work under
version 5 and crashing here.

The error message I get is the following:
--------
Error Number: 0x80040707
Description: DLL function call crashed: PfInstall.ConnectToDBEngine
Setup will now terminate.
-------

and in another case for a difference function, which is called after the
previous one
-------
Error Number: 0x80040704
Description: DLL function call resulted in bad stack
Possible incorrect prototyping: PfInstall.SetCompanyAndFinInformation
Setup will now terminate.
-------

I have updated the prototypes to include the BYREF V/s BYVAL qualifiers.

Can someone help please?

thanks

Hello Kedar,

Do you specify a return value for your dll? In InstallShield 5.x this was
not used, however in 6.x you need to specify a return value for the dll you
are calling.

I had the same kind of problem. It always showed the error "Description: DLL
function call resulted in bad stack".
What I've done is defining return value type (if the function has one) in
InstallShield decalaration and changed our DLL code to have the functions
declared in .def instead of using 'extern "C" _declspec (dllexport)'.
In most cases it worked for us.

having the same problem. error message:

Error Number: 0x80040704
Description: DLL function call resulted in bad stack

Possible incorrect prototyping: Dlg.InvokeRegistration
Setup will now terminate.

dll worked in is5x, but not in is6x.

what exactly do you mean by specifying a return value?

thanks.

I had the same problem and InstallShield told me to use the following
prototype cdecl instead of just prototype and it worked for me. Also see
below from Adam.
