Hello,

I am new to Delphi. I have a question about the environment variable manipulation. I want to know how to define a global environment variable through the program, and how to retrieve the value from existing environment variable?

Many thanks,

ngpk

The TRegistry class gives you access to the system registry.

 var Reg: TRegistry; Str: String;

 Reg := TRegistry.Create;

  // set the Registry directory, I forget how
  // Reg.Open('/Variable Path/');
  // Note: HKEY CURRENTUSER is default
 if Reg.ValueExists('GlobalVar') then
  Str := Reg.ReadString('GlobalVar') else
    Str := '';
 ....
 Reg.WriteString('GlobalVar',Str);


 Reg.Free;



Hope this gets you in the right direction, you didn't say which var you are looking for.
