Answer 1

To access a FastReport object’s components, one option would be to use the object’s FindComponent method, which returns the component by the specified name (or nil, if not found):

varname := YourFastReportObject.FindComponent('ComponentName');

Casting the result to an appropriate type, you could then access the component’s methods and properties, like in this example:

var
  varname: TfrxMemoView;

...

varname := TfrxMemoView(YourFastReportObject.FindComponent('ComponentName'));
if varname <> nil then
  varname.Width := varname.Width * 1.2;
