I have written a function in FPC that I have used in Delphi for many many years with out problem. Ok, here's a simple piece of code function myfunction(a, var b : dword) : boolean; var dllh : cardinal; fun : function (a : dword; var b : dword) : boolean; stdcall; begin result := false; dllh := loadlibrary('c:\windows\system32\somelib.dll'); if dllh <> 0 then begin fun := nil; fun := getprocaddress(dllh,'someproc'); if fun <> nil then result := fun(a,b); end else result := false; end; Now here's my problem - very simply if I compile this into a standard console application it works fine, however, if I compile it into the DLL I am planing to run it in it fails - the loadlibrary call ALWAYS returns 0x7C370000 which appears to be a memory address rather than a handle - the result is that the getprocaddress returns an invalid address and fails. So, why is the loadlibrary call failing (or returning this memory address) when in a DLL but NOT when it's in a console app. Any help would be great, as I cannot seem to find an implementation of GETLASTERROR to pass to SYSERRORMESSAGE to display any error from the OS if there is one !
