ReadArticleInGoogleGroups2

From 40tude Dialog Wiki

ReadArticleInGoogleGroups didn't work for me. So I wrote my own version, that doesn't use Postkey.

Program ReadArticleInGoogleGroups2;

uses
  Forms, StdCtrls;

//This version of the script tries to compensate for the crappy GoogleGroups beta interface//
//and retrieves the source of the message instead of the formatted version//
// If you prefer to use the original version of this script just comment out the line below //
  ShellExecute(0, 'open', PChar('http://groups.google.com/groups?dmode=source&selm='+MessageID), '', '', 
SW_SHOWNORMAL);

// and use ShellExecute(0, 'open', PChar('http://groups.google.com/groups?selm='+MessageID), '', '', SW_SHOWNORMAL); instead //

End.
