use a TBitmap, load/draw the bitmap, copy to the
clipboard, then use RichEdit1.PasteFromClipboard.

It goes a little somethin like this:

var
  b:TBitmap;
begin
  b := TBitmap.Create;
  b.LoadFromFile('c:\msngrpic.bmp');
  Clipboard.Assign(b);
  RichEdit1.PasteFromClipboard;
  b.Free;
end;

eddie_kho,

I have asked about  this image and memo a while back. Things haven't changed. It is still a 'can't do'
with a Memo.

Here is a copy of what I got from before:

********** copied

                                                                          Date: 09/09/2000 02:44PM PST
                There are some enhanced
                 TRichEdits that can handle this though, you can find one here:

                 http://www.trichview.com/

                 other alternatives are trying html instead (though most html controls don't let you edit the text well)
                 and ole controls that might, say, let you insert a word doc.

                 you _could_ save the _visible_ text as an image, but I'm not shure that's what he wants

                 the problem is that the memo doesn't actually contain the bmp - you've merely painted it on.  To save
                 as part of the memo's content you'd have to change controls to something that supports it.  You could
                 try something like an html renderer, or an enhanced richedit, but TMemo does not natively support this.
                  The closest I can imagine is to hack out you own parser  for load/save to file that would check for
                 images in the data file, and before you know it you've written an entire word proccessor :(

                 You can think about a solution using a special TRichEdit control instead

                 Mike and others,
                 I was looking to put them into one save but apparently that is not possible from what I read above.

                 I am still thinking that I may/must  have 3 saves
                 1. the image.
                 2. the text.
                 3  the position of the image on the memo.
                 but for the moment it is very late for this attempt so I will try in about 4-6 hours.

                 On the otherhand, Mike, what are you suggesting?
                 Do you have something in mind? I have a model  that one writes on the image and it is all together as
                 one there and saved. But there again  that is not an image on a memo and with text not on the image.


                 Delphi3.

                 Hi
                 Thanks to you all for helping out.
                 I gave the points to Mike as he made the first observations that this is impossible. I cannot see why
                 someone would ever want to paint the bmp on a memo other than the curiosity of doing it.

                 I have tried the saving the text, and the image and the position of the image,and  in that sense I can
                 put it all back but the moment I try add more  text ever thing fails.


                 So thanks to all again,

                 Delphi3

********** End of copied

I have D4 standard edition.  And even with RichEdit  I can't get an image to stick.
I have Win2k. I have decided to look at what does work (an image and text) on my computer
and tried to work that. Recently I have downloaded this and it allows me to work with Word.

http://support.microsoft.com/support/kb/articles/Q229/3/10.ASP

And today I worked with a 'safe call' to call 'WordPad'.

procedure TForm1.Button1Click(Sender: TObject);
var
  Str1, Str2, Totalcmdline: string;
begin
  Str1 := 'C:\...\Windows NT\Accessories\WordPad.exe';
  Str2 := ExtractFilePath(Application.exeName) + 'FormS.rtf';
  Totalcmdline := str1 + ' "' + str2 + ' "';
  Cprocess(Totalcmdline, Self);
end;

procedure TForm1.Cprocess(sExecuteFile: string; Sender: TObject);
var
  pi: TProcessInformation;
  si: TStartupInfo;
begin
  FillMemory(@si, sizeof(si), 0);
  si.cb := sizeof(si);
  CreateProcess(nil, PChar(sExecuteFile), nil, nil, false, NORMAL_PRIORITY_CLASS, nil, nil, si, pi);
  // close up shop...
  closeHandle(pi.hProcess);
  closeHandle(pi.hThread);
end;
 
If you want more details please comment me back.
