Hi!

I m trying to verify an equipment status in a emulator program using a DLL.

PB -> DLL -> read the emulator equipament status

Using the emulator program  works well.

 

In Powerbuilder 2019 R2 - BUILD 2353

- in Global External Functions:

function string ConsultarSAT ( long al_nrSession ) Library "SAT.DLL"

 

- Calling the function:

string ls_status

ls_status = consultarSAT( 123456 )

 

I pass a number of 6 digits and return a string.

 

But, when i execute occurred the error:

Specified argument type differs from from required argument type at runtime in DLL function consultarsat.

(Invalid stack pointer on return from function call) at line ...

 

I tried many different arguments variables, but i didn't solve this

The sat.dll follow attached

I appreciate some help.

Thanks!

Eduardo
