unimdbgrid->onfieldimage

[Roberto Nicchi]

Hi,

I have an unimdbgrid (mobile version) with dataset and 10 rows for page. I load into a column the path ed the relative image. I use grid.fieldimage to load the image:

procedure form.<unimdbgrid>FieldImage(const Column: TunimDBGridColumn;
  const AField: TField; var OutImage: TGraphic; var DoNotDispose: Boolean;
  var ATransparent: TUniTransparentOption);
var outimageBMP:TBitmap;
begin  

if Column.FieldName='path_immagine' then
  begin
    if ( (afield.AsString<>'')) then //(the complete path)
    begin
      outimageBMP := TBitmap.Create;
      try
        OutImage := TBitmap.Create;
        imgfiletobmp(afield.Value,outimageBMP,false,'AUTO',60,60);
        OutImage.Assign(outimageBMP);
      finally
        outimageBMP.Free;
      end;
    end
  end;
end;

 

This is the problem:

I have a dataset with more than 2600 records, if I set imgfiletobmp(afield.Value,outimageBMP,false,'AUTO',60,60), after some seconds I recive the message "connection error comunication failure: ", but if I set, for example, imgfiletobmp(afield.Value,outimageBMP,false,'AUTO',40,40), it works correctly.

Someone can explain me why?

Thanks
