  2.34. How to print a picture that stored in a file?
  
  a) use TfrReport.OnBeforePrint event:
  
  if View.Name = 'Picture1' then
  TfrPictureView(View).Picture.LoadFromFile(...);

  Already tried before to post my example... it doesent works same error #53
  Any other ideas?
  
  Basically I' ve to build both path and file name at runtime before to load it and print; if I write something like ..LoadFromFile('C:\Images\Img01.jpg') it works, but
  if it refer the path from a prevalorized variable it doesen't find correct path and image name. May u test it for me and send an example by mail? thanx

  This should be a clue
  LoadFromFile('C:\Images\Img01.jpg') it works,
  
  so either your variable's value is wrong or
  you need to pass the opening and closing apostrophes
  LoadFromFile('+varname+');
  check to make sure your variable contains the complete path and file extension.

  Something is wrong. Or tip in FastReport site or in 2.57 source.
  Herein is the right code:
  
  procedure TStmpTab.StTabBeforePrint(Memo: TStringList; View: TfrView);
  var cStr: string;
  begin
  if View.Name = 'Picture1' then
  begin
  cStr := Trim(DM.cPath + 'Scanner\' + IntToStr(DM.ArcScaL.FieldByName('NroCip').AsInteger) +
  DM.ArcScaL.FieldByName('NroDoc').AsString + '.jpg');
  
  if FileExists(cStr) then
  (StTab.FindObject('Picture1') as TfrPictureView).Picture.Bitmap.LoadFromFile(cStr)
  else
  (StTab.FindObject('Picture1') as TfrpictureView).Picture.Bitmap := nil;
  end;
  
  I added .Bitmap to incapsulate LoadFromFile func and not just picture.LoadFromFile
  
  it works both with
  (StTab.FindObject('Picture1') as TfrPictureView).Picture.Bitmap.LoadFromFile(cStr)
  
  and
  
  TfrPictureView).Picture.Bitmap.LoadFromFile(cStr)
  
  cheers

  Hi Gord
  
  thanks for suggestions. I tried LoadFromFile('+myVar+')
  
  Same #53 error
  
  I already debugged instructiond and Fileexists(myDir) reports true..
  if I add .Bitmap, image is displayed.

  this works fine for me no need for extra find and cast
  // wpath string global set in forms onshow event
  WPath := ExtractFilePath(ParamStr(0));
  
  procedure TForm1.frReport1BeforePrint(Memo: TStringList; View: TfrView);
  VAR
  cstr:string;
  begin
  cstr := wpath+'mytest3.jpg';
  if View.Name = 'Picture1' then
  BEGIN
  if FileExists(cStr) then
  begin
  TfrPictureView(View).Picture.LoadFromFile(cstr);
  end
  else
  begin
  // showmessage(cstr +' not found');
  end;
  end;
  end;

  Dunno Gord.
  
  Variable is perfectly valorized (otherwise no chance to pass the Fileexists() condiction, but it doesent works except if I cast bitmap to picture.
  
  I noted anyway, to had same problem when I valorize an TImage comp using same LoadFromFile() func.
  
  Image1.Picture.LoadFromFile(myVar) it doesent works,
  Image1.Picture.Bitmap.LoadFromfile(myVah) works.
  
  I'm currently using XP with SP2, and some Kernel changement is the problem, I guess.
  
  what's important to found solution!
