Convert CString to unsigned short in MFC?

[Rmck87]

Hello, I am attempting to convert a CString variable (strTemp, which is coming from an edit control) into a WORD (m_cmd, aka unsigned short). I have been trying to figure this out for over a week now and have come to nothing.

I am familiar with sscanf and was using:

sscanf_s(strTemp, "%x", &m_cmd);

However, %x is used for DWORDS, and every time I would use this, it would overwrite whatever m_cmd was next to in the stack.

Thanks in advance!

Try
I am assuming that m_cmd is an unsigned short.
m_cmd = (unsigned short)atoi(strTemp);

What was wrong with the solutions proposed in the other thread?

What is wrong? Seems to me you said that it overwrote what was on the stack. That appears to be a problem (AKA wrong) to me. You are passing the address to an object probably an unsigned short (16 bits) and telling sscanf to fill it with a DWORD (64 bits). Seems pretty self explanitory on what the problem is.

Regards.

I was talking to the OP, Rmck87.

There is another thread I linked to with several solutions (including yours), and I was wondering what was wrong with those that required him or her to start a new thread with the same question.
