Actually i am reading some text from file so it will be a stream of Bytes, i need to send bytes to MFC Activex control and i need to read it. I have tried in many ways but i couldnt so i am thought going this method. Do you have solution for this.

// Global buffer.<br />
BYTE* p = NULL;<br />
<br />
// Some function.<br />
BYTE* ReadFileIntoBuffer(...)<br />
{<br />
  if(!p) { p = new BYTE[file_size]; }<br />
  // ReadFile(...);<br />
}<br />
<br />
// The other function.<br />
bool PassToActiveXCtrl(...)<br />
{<br />
  return ctrl.Input(p, file_size);<br />
}

HGLOBAL hMem;<br />
hMem = GlobalAlloc(0, (800*sizeof(char)));<br />
if(NULL == hMem)<br />
	return;<br />
char* szVal = (char*) GlobalLock(hMem);<br />
<br />
memcpy(szVal, buffer, 800);<br />
if(!OpenClipboard(NULL))<br />
	return;<br />
if(!EmptyClipboard())<br />
	return;<br />
HANDLE hData = SetClipboardData(CF_TEXT , hMem);<br />
	if(NULL == hData)<br />
		return;<br />
if(!CloseClipboard())<br />
	return;<br />
if(!GlobalUnlock(hMem))<br />
	return;

if(!IsClipboardFormatAvailable(CF_TEXT))<br />
	return -1;<br />
OpenClipboard(NULL);<br />
     hgbl = GetClipboardData(CF_TEXT);<br />
char* szVal = (char*) GlobalLock(hgbl);<br />
char chScriptData[128];<br />
<br />
GlobalUnlock(hgbl);<br />
CloseClipboard();
