Delphi TypeInfo for generic records -


i'm trying use generic records rtti, ran problem type info. know why following won't compile using delphi 2010?

program generictypeinfo;  {$apptype console}  uses   typinfo,   sysutils;  type    tmyrec<t> = record   public     value: t;   end;    tmyint = tmyrec<integer>;   tmystring = tmyrec<string>;  begin    try     writeln(gettypename(typeinfo(tmyrec<integer>)));     <--- works fine     writeln(gettypename(typeinfo(tmyrec<string>)));      <---       writeln(gettypename(typeinfo(tmyint)));              <--- won't compile     writeln(gettypename(typeinfo(tmystring)));           <---   nor this!!   except     on e: exception       writeln(e.classname, ': ', e.message);   end;    readln;  end.

the lines indicated above generate following compiler errors:

[dcc error] generictypeinfo.dpr(24): e2134 type 'tmyint' has no type info [dcc error] generictypeinfo.dpr(24): e2134 type 'tmystring' has no type info

i can't what's big difference between 2? admit i'm not low-level expert, why compiler treat differently? need work tmyint , tmystring types.

thanks help.

this bug in delphi 2010 has been fixed xe , higher.

but there workaround.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
