Using the clipboard in a windows console application

[tobibo1]

Hello,


I use Lazarus 1.6 64bit with FPC 3.0.0 on Win7home 64bit.
On Lazarus I created a console-applicaton-project and added the following source:
program test_clipboard;

{$APPTYPE CONSOLE}

uses
  SysUtils,
  Clipbrd, interfaces;

begin
  Clipboard.AsText := '10' + #9 +'15' + sLineBreak + '12';
end.

Additionally I added the dependency to LCL and LCLBase. Otherwise the units Clipbrd  and interfaces will not be found.
So far so good. The Program is compiled and work with no errors. But the exe-file has a size of 18MB.
Is there a way to compile the code directly from the console to reduce the size of the application?

Thanks
Tobias

Basically you should switch to release mode.

There is no difference to compile from the console or from Lazarus.
If you follow the guidance URL from @GetMem, then size will be about 2.4 mb.
But you can write directly to WinAPI. For example, the size of this program approximately 45 KB:

Code: Pascal  [Select]

1. program Project1;
2.  
3. uses Windows;
4.  
5. function AddDataToClip(Format: UINT; const Data; Size: PtrUInt): Boolean;
6. var
7.   HMem: THandle;
8.   P: Pointer;
9. begin
10.   Result := False;
11.   HMem := GlobalAlloc(GMEM_MOVEABLE, Size);
12.   if HMem <> 0 then
13.   begin
14.     P := GlobalLock(HMem);
15.     if P <> nil then
16.     begin
17.       Move(Data, P^, Size);
18.       GlobalUnlock(HMem);
19.       Result := SetClipboardData(Format, HMem) <> 0;
20.     end;
21.   end;
22. end;
23.  
24. function PutTextToClipboard(const S: string): Boolean;
25. var
26.   W: UnicodeString;
27. begin
28.   Result := False;
29.   if OpenClipboard(0) then
30.   try
31.     if EmptyClipboard then
32.     begin
33.       W := UTF8Decode(S);
34.       Result := AddDataToClip(CF_UNICODETEXT, Pointer(W)^, SizeOf(UnicodeChar) * Length(W));
35.     end;
36.   finally
37.     CloseClipboard;
38.   end;
39. end;
40.  
41. begin
42.   PutTextToClipboard('10' + #9 +'15' + sLineBreak + '12');
43. end.
