Thanks for replying Julian, I will give it a go and see

I am currently working on a Labeling program in Delphi 7 and am using your wpForm component, the problem that I am having is that
I am using 2 wpFormEditor controls, one for the label designer and one for the preview (they are both on the same form).

After the label design is finished I output the report page by page, first creating a file and then using the write page method. (see below)

if  WPFReportEngine2.ReportLoaded then		      WPFReportEngine2.Close;		//Create the report file to append each page to		      WPFReportEngine2.CreateFile(installpath+'\selfit\Import\PrntPreview.wpr');		 for i := 0 to (EndBadgeNo-StartBadgeNo) do		Begin		      WPFReportEngine2.WritePage(i);		end;

This all works fine I then load the report into the 2nd wpfFormEditor control (using the execute procedure below) and set it up like a preview

procedure TForm1.Execute(Printing: Boolean; const FileName: string);
		begin


			    if fd <> nil then
			     begin
			         fd2.Form.Assign(fd.Form);
			         fd2.Page.Assign(fd.Page);
			         fd2.LabelDef.Assign(fd.LabelDef);
			         fd2.CurrentPage := 1;
			    end;

            	         if FD2.ReportLoaded  then WPFReportEngine1.Close;


	                     Try
            		         WPFReportEngine1.OpenFile(FileName);
		               Finally
	                                 WPFReportEngine1.SeekToPage(0,0);

			//Setup the form designer in preview mode
		                FD2.options := FD2.Options + [wpfpreviewmode];
	                           fd2.Labeldef.enabled := false;
                  		   fd2.Labeldef.setpapersize := true;
		               FD2.RefreshData(false);
	                     end;


		end;

This also works fine, the problem is that when I put an image on the label thatI am designing and preview the report in this way (say for 200 labels)
a lot of memory is used up (this depends on the size of the image that has been inserted) and I can find no way to free up the used memory??
I have tried loading in a blank report but this doesn't help and everytime I preview the report I lose more and more memory. As the 2nd preview
formEditor is on the same form as the designer and is linked throughout the program (nearing the end of the project) I cannot create and destroy it
at runtime,

I would be very greatful if someone could help with any suggestions to this problem

many thanks

This only seems to hide the Graphics in the print preview I want to hide objects while designing a form in the FormEditor Component

How can I Show and Hide a TWPFGGraphic?

I need to be able Click on a graphic and return it's postion on a form.

I cannot see any methods to do this, so I am using the Graphics top property which retuns the top position in pixcels.

How ever this is of no use as I need the co-ords in Cm (the unit I am working in)

I can't convert the pixcels either as the form doesn't start at 0,0 in the editior object

ShowMessage(formatfloat('0.00', ((http://FD.SelectedObject.Top/PixcelsPerInch)*2.54)));

I have tried this method looking at the print preview unit and I'm using

the following 2 procedrues

procedure TForm1.Button4Click(Sender: TObject);
var f : String;
    a,b : Boolean;
begin
  try
    f := WPFReportEngine2.CreateTemporaryFile;
    WPFReportEngine2.CreateReport;
  finally
    WPFReportEngine2.Close;
  end;
   if f <>'' then Execute(FALSE, f);
end;


procedure TForm1.Execute(Printing: Boolean; const FileName: string);
var
  dia : TReportPreview;
begin
     if fd <> nil then
     begin
         fd2.Form.Assign(fd.Form);
         fd2.Page.Assign(fd.Page);
         fd2.LabelDef.Assign(fd.LabelDef);
         fd2.CurrentPage := 1;
     end
//     else WPFReportEngine1.Open(FileName);
end;

The problem is that I am using fields and when the page is displayed in the 2nd form designer I only get a preview of the first label or which ever record is being viewed?

How do I view all the labels?

I would like to be able to change the font information for each line in a wpfRTFText object dynamically through code, I assume that you need to select a range of text and then set the attributes, any help would be great

thanks
