A DLL function can't return a string. Please check the DLL docs. It should have the returned string as a parameter passed by reference.

This is a sample for REGQUERYVALUE:

Code: Select all  Expand view
DLL32 FUNCTION REGQUERYVALUE( hKey AS LONG, cValueName AS LPSTR, nReserved AS LONG, @nType AS PTR, @cData AS LPSTR, @nSize AS PTR ) AS LONG;
      PASCAL FROM "RegQueryValueExA" LIB "advapi32.dll"


Please note

Code: Select all  Expand view
@cData AS LPSTR
