I use an Timage for capture an image of Clipboard (Ctrl+V), then when the user press the
button (save) my code is:

Procedure Tform1.Button1click(Sender:Tobject);
var
  st:Tfilestream;
begin
  if not table1.findkey([key.text]) then
  begin
    table1.appendrecord([key.text,name.text]);
    st:=Tfilestream.create('c:\temp\temp.xxx',fmcreate);
    image1.picture.graphic.savetostream(st);
    Table1.edit;
    Tblobfield(table1.fieldbyname('Photo')).loadfromstream(St);
    table1.post;
  end;
end;
     
and i have other Button

Tform1.Button2click(Sender:Tobject) ;
var
  st:Tfilestream;
begin
  if table1.findkey([key.text]) then
  begin
    name.text:=table1.fieldbyname('Name').asstring;
    st:=Tfilestream.create('c:\temp\temp.xxx',fmcreate);
    Tblobfield(Table1.fieldbyname('Photo')).savetostream(st);
    image1.picture.graphic.loadfromstream(st);
  end
  else
    caption:='Error';
end;

the 2 procedures not mark noting error, but when i press the Button2 only The Name.text
are filled but the Image1 noting

why

Thanks

The LoadFromStream call does not recognise the file extension. You should set it to the approprite one (eg: .BMP for bitmap etc)

Cheers,

but the extension is that of less, since I have proven without extension, or I have to put you the extension .BMP, what is the way perfect, can you  illustrate me with any code the correct form?

I think you should change this line

   st:=Tfilestream.create('c:\temp\temp.xxx',fmcreate);

to this

   st:=Tfilestream.create('c:\temp\temp.bmp',fmcreate);

I would also reset the stream position before reading in the image eg:

   st.position := 0;
   image1.picture.graphic.loadfromstream(st);
