CreateProcess CreatePipe - gather Stderr output not working

Im trying to create a process and send the output to a pipe which I
read after the
process runs so I can see whats wrong.  In this case Im trying to call
it with pscp
(which is why I hardcoded the error Im looking for btw).  Ive tried
googling this and
Ive seen many variations of this code, but so far I cant get it to
work the way I was
expecting it to.

In my debug output, ReadFile Avail <0> is as far as it gets and then
I know its hanging because when I do it in the command line It also
hangs with the
string Im looking for, "Server refused our key", but I cant see why
the following code
isnt getting my Stderr output as I want.  And yes, Im a newbie still.

Id appreciate any help on getting this to work and bulletproofing it
more also.

bool doSystem(LPSTR cmd)
	HANDLE read_stderr, wr_stderr;

        STARTUPINFO si;
	ZeroMemory(&si, sizeof(si));
	si.cb = sizeof(si);	// Must set the size of structure

	sa.nLength = sizeof(SECURITY_ATTRIBUTES);
       sa.bInheritHandle = FALSE;
       sa.lpSecurityDescriptor = NULL;

       if (!CreatePipe(&read_stderr, &wr_stderr, &sa, 0))  //create
stderr pipe
 		dmsg(TERR, "CreatePipe %d", GetLastError());
                return false;

      si.wShowWindow = SW_HIDE;
      si.hStdError = wr_stderr;

	BOOL ret = CreateProcess(NULL, cmd, NULL, NULL, FALSE,
                            CREATE_NEW_CONSOLE, //CREATE_NO_WINDOW,
			NULL, NULL, &si, &pi);
	if (!ret)
		dmsg(TERR, "CreateProcess FAILED");
                return false;
	//WaitForSingleObject(pi.hProcess, INFINITE);

	dmsg(TINFO, "Process Started");

	char buf[MAX_BUF];
	DWORD bread, avail;

	if (!PeekNamedPipe(read_stderr, buf, MAX_BUF - 1, &bread, &avail,
		dmsg(TERR, "PeekNamedPipe stderr");
		dmsg(TINFO, "ReadFile Avail <%d>", avail);
		ReadFile(read_stderr, buf, 1023, &bread, NULL);
		dmsg(TINFO, "bread <%d>", bread);
		dmsg(TINFO, "BUF: <%s>", buf);
		if (bread > 5)
			if (!strcmp(buf, "Server refused our key"))
				dmsg(TERR, "Server refused our key");

	return true;

formula fill not working correctly in 2007
If I use the fill handle to copy a formula, the formulas are well copied, but the results are not. Exemple: The formula in A3 is =A1+A2. If I copy the formula to B3 it reads =B1+B2, which is correct. The result given in B3 however is not B1+B2 but the same result as in A3. I have to recalculate the formule in B3 for the correct result. In previous versions Excel did this automatically.

URL/Hyperlink not working for recipients

I send our users an e-mail with a URL to the bat file (e.g. \\server123 \Application\install.bat). The URL cannot launch the bat file and search Locate Link Browser dialog opens instead. The work around is to cut and paste the URL into the Start\Run dialog where it works fine. (I think this implies that the UNC is defined properly.)
