Well, no. That's not what I was looking for, and I don't think that screen shots from the Class Wizard will help. I had several questions that I thought were clear enough when I wrote them the first time. For ease of reference, here they are again:

• You've shown a bit of code. I suppose it's extracted from some event handler function that's magically called by the MFC framework. Is that correct?
• If so, which handler function is it?
• If not, what then?
• What, exactly, do you mean by the statement "I've found that the edit box is either set to "CString" or "CEdit" but not both ..."?
• The edit box is almost certainly an object of type CEdit. I don't understand what you mean when you talk about "setting" it to some other type. Do you mean that you are assigning the CEdit box to a CString object?

What I'm trying to sort out here is exactly where in your program that the snippet you posted came from, how 'm_strDeviceAddress' is declared, how its value gets set, and what, exactly, you mean when you say that the edit box is "either set to "CString" or "CEdit" but not both ...".

Can you give simple and direct answers to the individual questions above instead of just ignoring them? Can you post the entire program (including the VC++ project files) so that we can see how the little snippet fits in with everything else?
