CMFCPropertyGridProperty formatting

Question

I've asked this question over in the BCGSoft forums, but things seem to be pretty quiet over there and I thought I'd try here.

CMFCPropertyGridProperty uses the same format string (eg m_strFormatDouble) for scanning input (::TextToVar) and output formatting (::FormatProperty). This means that a format string that specifies precision, such as _T("%.3lf") for a property of type double (VT_R8), works fine in the CString.Format used for output, but fails in the _stscanf_s used for input in TextToVar. So, as far as I can see, there's no way to format the display of float or double properties, eg to restrict the display to 3 digits after the point.

Has anybody resolved this problem?

Answer 1

I seem to have answered my own question here. I've redefined the TextToVar and FormatProperty functions in a class that inherits from CMFCPropertyGridProperty to do the correct formatting, and all's well now.

Can you provide your code? I am fighting the same battle, and would love to borrow from someone who has already made it work!
