Thread: Adding text to the Windows Clipboard (API)..

I've tried several things.. but i keep getting errors in the SetClipboardData() line.
The problem I have is when trying to add Strings to it.

SetClipboardData(CF_Text,"Hi");

does not work obviously
I suppose I have to cast the string or something, or maybe do something with pointers.. Please help..

SetClipboardData needs the memory set to exist on the heap (and in my experience - often best to use the default process heap as opposed to one of the runtime heaps used with new or malloc)

Code:

#include <windows.h>
#include <iostream>
#include <string>
using namespace std;


int main()
{
	string strBuff = "Hello World";
	
	if(!OpenClipboard(0)){
		cout << "Error opening clipboard";
		return 1;
	}

	LPVOID lpv = 
		HeapAlloc(GetProcessHeap(),HEAP_ZERO_MEMORY,
		strBuff.length()+1);

	if(!lpv){
		cout << "Error getting memory";
		return 1;
	}

	CopyMemory(lpv,strBuff.c_str(),strBuff.length());
	EmptyClipboard();

	if(!SetClipboardData(CF_TEXT,lpv)){
		cout << "Error Setting data";
		return 1;
	}

	CloseClipboard();

	HeapFree(GetProcessHeap(),0,lpv);

	return 0;
}
