BOOL  ShellExecAndWait ( TCHAR* szAppName, TCHAR* szParam )
{
 SHELLEXECUTEINFO stExeInfo;

 memset ( &stExeInfo, 0, sizeof(stExeInfo) );
 stExeInfo.cbSize = sizeof(stExeInfo);
 stExeInfo.fMask = SEE_MASK_NOCLOSEPROCESS;
 stExeInfo.lpVerb = L"open";
 stExeInfo.lpFile = szAppName;
 stExeInfo.lpParameters = szParam;

 if ( !ShellExecuteEx ( &stExeInfo ) ) return FALSE;
 if ( WaitForSingleObject ( stExeInfo.hProcess, INFINITE ) == WAIT_FAILED )
return FALSE;
 if ( !CloseHandle ( stExeInfo.hProcess ) ) return FALSE;    // <---
problem!

 return TRUE;
}

the problem is at the CloseHandle line, CloseHandle returns FALSE and
GetLastError returns Invalid handle code.  but if i use CreateProcess then
CloseHandle for process and thread handle works without error.  somebody got
any clue?

thanks in advance,
ahmoy law
