I need to output a double to a static control. Is there any way to convert a double to a string? (I know about the SetDlgItemInt function, but I believe that only works for ints. I MUST make the output a double, or some data type that supports decimals) thanks, Chris

You can use the MFC CString class to create a string object. One of the class members Format is able to do the conversion for you.

CString s;
double x;

x = 23.12345;
s.Format("%7.3f", x);
// Outputs 23.123
AfxMessageBox(s);

Hope this helps. You can read more about CString in the help file.

Excellent, that works great. One more Q though, :) How would I go about getting a double from an edit box also? Thanks

Going the other way, I believe you can use the atof() Function. This converts an ascii value to a real.

double x;

x = atof(m_dStringVal);

Hope that works.

Actually I found an even easier way. just associate a double with the edit control, and when you call UpdateData, you can then just use the member variable. THanks again for the help on output.
