4. Write something weird at the very beginning of StdAfx.h

Which of the above is wrong?

#include <WinAble.h><br />
<br />
#define _MAX_KBDINPUT_LENGTH_ 50<br />
<br />
   INPUT KBa[ _MAX_KBDINPUT_LENGTH_ ];<br />
   ::ZeroMemory(KBa, sizeof(KBa));<br />
<br />
   UINT KBn = 0;  // how many keyboard key msgs to send (this is a counter)<br />
<br />
   Stuff the KBa array with KEYEVENTF_KEYUP and KEYEVENTF_KEYDN (0) messages. like this...<br />
<br />
			KBa[KBn].type       = INPUT_KEYBOARD;<br />
			KBa[KBn].ki.wVk     = wVk;<br />
			KBa[KBn].ki.wScan   = wScan;<br />
			KBa[KBn].ki.dwFlags = 0;  // KEYDOWN is ZERO<br />
                        KBn++;<br />
			KBa[KBn].type       = INPUT_KEYBOARD;<br />
			KBa[KBn].ki.wVk     = wVk;<br />
			KBa[KBn].ki.wScan   = wScan;<br />
			KBa[KBn].ki.dwFlags = KEYEVENTF_KEYUP;<br />
                        KBn++;<br />
<br />
Then, set focus to the target window.  If its not a window your process owns, you must do the following<br />
<br />
		// set focus to target foreign window. Get owning thread of target window.<br />
		DWORD tWNDthread = ::GetWindowThreadProcessId(hwndTARGET,0);<br />
		if (!tWNDthread)<br />
		{<br />
			AfxMessageBox("zSendKeys FAILED to get ABF Thread Id!");<br />
			bValid = FALSE;<br />
		}<br />
<br />
		// MUST attach to it<br />
		BOOL bAttached = FALSE;<br />
		bAttached = AttachThreadInput(GetCurrentThreadId(),tWNDthread,TRUE); // TRUE means ATTACH<br />
<br />
		if ( bAttached )<br />
		{<br />
			::SetForegroundWindow(hwndTARGET);  // pop to top<br />
			::SetFocus(hwndTARGET);             // set it to accept future keystrokes<br />
			<br />
			//mission accomplished, now release my hook into their thread.<br />
			AttachThreadInput(GetCurrentThreadId(),tWNDthread,FALSE); // FALSE means DETACH<br />
<br />
		} else<br />
		{<br />
			AfxMessageBox("zSendKeys FAILED to attach to ABF Thread Id!");<br />
			bValid = FALSE;<br />
		}<br />
<br />
		// do the deed<br />
		if (bValid) bValid = ::SendInput(KBn,&KBa[0],sizeof(INPUT)); // <-- note KBn and sizeof(INPUT) might be different<br />
<br />
	   	// no matter what, lets be safe, and set the forground and focus here again<br />
