When you call GetBuffer, you cannot do ANYTHING with the CString object until you call ReleaseBuffer. In the above case, you should just be calling AfxMessageBox(input1); without the GetBuffer/ReleaseBuffer calls.

do you have to release the buffer right after getBuffer?

Why do you need to? What is it that the CString object is not doing that char* will?

You can't parse each char of the CString string like a char*...?
