ReportBuilder 7 no longer includes the global ppParentWnd due to modifications required for thread-safety.

You have two choices:

1. Modify TWPCustomRichTextForPP (or create a descendant class). Override the CreateParams as shown below. CreateParams is a protected method of TWinControl. (note: This is the approach that RB uses so that RichText can be thread-safe for RB Server.)

   procedure TWPCustomRichTextForPP.CreateParams(var Params:
   TCreateParams);
   begin
   
     inherited CreateParams(Params);
   
     {remove ws-child so that no parent window is required}
     Params.Style := Params.Style and not(WS_CHILD);
   
   end; {procedure, CreateParams}

   Pascal

   Copy
2. Create an invisble form and use that as the parent. (Note: This is not thread-safe).
