COPY SCREEN TO WORD
Ralph,
I found a solution from Delphi3000.com
for your reference.
Gordon
procedure SimulateKeystroke(Key : byte; extra : DWORD);
begin
keybd_event(Key, extra, 0, 0);
keybd_event(Key, extra, KEYEVENTF_KEYUP, 0);
end;
procedure TForm1.Button2Click(Sender: TObject);
begin
{Capture the entire screen to the clipboard}
{by simulating pressing the PrintScreen key}
SimulateKeystroke(VK_SNAPSHOT, 0);
end;
procedure TForm1.Button3Click(Sender: TObject);
begin
{Capture the active window to the clipboard}
{by simulating pressing the PrintScreen key}
SimulateKeystroke(VK_SNAPSHOT, 1);
end;

Gordon,
yet cleaner:
var
formImage: TBitmap;
begin
formImage := GetFormImage;
try
Clipboard.Assign(formImage);
finally
formImage.Free;
end;
end;
Regards
Ralph

The following will get you the client area (everything except the caption
bar):
procedure TForm1.Button1Click(Sender: TObject);
var
data: cardinal;
format: Word;
palette: HPALETTE;
begin
GetFormImage.SaveToClipboardFormat(format, data, palette);
Clipboard.SetAsHandle(format, data);
end;

Actually, Ctrl+Print Screen isn't defined by Windows (not mine, anyway).
For the whole screen, it's just plain Print Screen. A number of graphics
packages will set up functions for other Print Screen combinations.
As for copying the form, I guess we're assuming a graphical image. The
keyboard solution given would work, but I don't think it's appropriate for
a programmatic method. Maybe it's just me, but I don't like solutions that
rely on emulating user input through the *_event functions--for one thing,
they imply certain keyboard shortcuts exist and certain window focus
conditions.
My method would use the wm_Print message. Something like this:
Bmp := Graphics.TBitmap.Create;
Bmp.Height := SourceForm.Height;
Bmp.Width := SourceForm.Width;
SendMessage(SourceForm.Handle, wm_Print, Bmp.Canvas.Handle, prf_Children
or prf_Client or prf_NonClient);
At this point, you should have a bitmap image of the form. To place it on
the clipboard, use Clipboad.Assign(Bmp). I'm a little wary of using the
clipboard to actually _transfer_ information between programs
automatically. Unless the menu command is "Copy to clipoard and paste in
Word," I'd use something else. For example, if the text is more like,
"Send image to Word," then the clipboard should not be used at all. The
clipboard is for the user's data, not the program's. Program information
can be sent via automation. If the menu command really does make it clear
that the clipboard will be used, then I would ask why you're limiting it
to Word. Thousands of applications can take bitmap information from the
clipboard, including WordPerfect, Wordpad, and StarOffice, so a command
aimed only at Word isn't a great design.
