Problem with old GetPrivateProfileString

I am using GetPrivateProfileString to retrieve some data for a program I am working on. Can anyone tell me why the code below does not work as well as which it often breaks at runtime.

LPCTSTR lpAppName2;
LPCTSTR lpKeyName2;
LPCTSTR lpDefault;
LPTSTR  lpReturnedString;
DWORD   nSize;
LPCTSTR lpFileName2;

	GetPrivateProfileString(
		lpAppName2 = TEXT ("Section11"),
		lpKeyName2 = TEXT ("FirstKey1"),
		lpDefault  = TEXT ("String Not Found") ,
		lpReturnedString ,
		nSize ,
		lpFileName2 = TEXT ("c:\\aa\\test2.ini")
		);
	Application->ProcessMessages();
	ShowMessage(lpReturnedString);
