Hello,

 

I would like to load DFM files at runtime, for allows me modify uniforms without recompile.

 

I am trying to load without succes via this function:

procedure LoadComponentFromFile(Component: TComponent; const FileName: TFileName);
var
  FileStream : TFileStream;
  MemStream : TMemoryStream;
  i: Integer;
begin
  MemStream := nil;

  if not Assigned(Component) then
    raise Exception.Create('Component is not assigned');

  if FileExists(FileName) then
  begin
    FileStream := TFileStream.Create(FileName,fmOpenRead);
    try
      for i := Component.ComponentCount - 1 downto 0 do
      begin
        if Component.Components[i] is TControl then
          TControl(Component.Components[i]).Parent := nil;
        Component.Components[i].Free;
      end;

      MemStream := TMemoryStream.Create;
      ObjectTextToBinary(FileStream, MemStream);
      MemStream.Position := 0;
      MemStream.ReadComponent(Component);
      Application.InsertComponent(Component);
    finally
      MemStream.Free;
      FileStream.Free;
    end;
  end;
end;
