I am trying to create a 16-bit "cover" dll that will call a 32-bit dll from a Powerbuilder program. In my 16-bit "cover" dll, I am trying to LoadLibrary ("the name of the 32-bit dll"). When I execute the PB program, I get to my 16-bit dll, but the LoadLibrary fails with a rc of 21 (Application requires Windows 32-bit extensions). Any ideas on how I can get this to work? Really appreciate any help I can get!
