C++ Builder, copy to clipboard

Question

Trying to copy to Clipboard as I found in Delphi Example, but got error

[bcc32c Error] Unit1.cpp(40): use of undeclared identifier 'Clipboard'

I connected library Vcl.Clipbrd

#include <vcl.h>
#pragma hdrstop
#pragma Vcl.Clipbrd
#include "Unit1.h"
//---------------------------------------------------------------------------
#pragma package(smart_init)
#pragma resource "*.dfm"
TForm1 *Form1;

.....................

void __fastcall TForm1::Button3Click(TObject *Sender)
{
Clipboard()->AsText=DBLookupListBox12->DataField;
}

Answer 1

You are getting the error because you did not #include the header file that declares the Clipboard() function.

You need to remove #pragma Vcl.Clipbrd, and instead use #include <Vcl.Clipbrd.hpp> (since XE8) or #include <Clipbrd.hpp> (earlier versions). Note that a separate documentation page says you need to use <vcl\Clipbrd.hpp> instead. That statement is not up-to-date.

Try this:

#include <vcl.h>
#pragma hdrstop
#include "Unit1.h"
#include <Vcl.Clipbrd.hpp>
//---------------------------------------------------------------------------
#pragma package(smart_init)
#pragma resource "*.dfm"
TForm1 *Form1;

void __fastcall TForm1::Button3Click(TObject *Sender)
{
  Clipboard()->AsText=DBLookupListBox12->DataField;
}
