How to fix "Warning'

[pgraham9999 0]

I have a unit in a large project that does a zip backup of the data files at close.  The main zip procedure declares a variable 

 

Dir:TDirectory;

 

which is used to retrieve file names for the backup:

 

sl:=StrArray(Dir.GetFiles(SourceDir));

 

I then pass sl to the zip file.  It works correctly.  However, compile gives a warning "variable 'Dir' is declared but never used".  If I remove the variable, compile fails.  I don't like to leave warnings!  How can I remove this one?

just write

sl:=StrArray(TDirectory.GetFiles(SourceDir));

and drop "Dir"

It is a class method. Use the class as the subject of the method call.

That was too easy!  The following

 

 {$IFDEF MSWINDOWS}
  ReportMemoryLeaksOnShutdown := DebugHook <> 0;
 {$ENDIF}
 

gets warning "Symbol 'DebugHook' is specific to platform"  Didn't I just say that!

To remove that warning, go to menu, project, options, building, Delphi compiler, hints and warnings and expand output warnings and set platform symbol to false.

There are also directives for these warnings:

{$WARN UNIT_PLATFORM OFF}
{$WARN SYMBOL_PLATFORM OFF}

SYMBOL_PLATFORM OFF  did it!

 

Thanks.  My mind is just too old for the little things!
