setting fixed floats in edit box

I'm trying to set the number that appears in an edit box to a fixed decimal point. I only want 2 place holders after a decimal point, instead of how many exist. I know how to do this using iomanip.h settings on console programs, but can anyone point me to the right direction using windows programing with edit boxes?

below is some sample code of how I set up my code to udpate the edit boxes:

Code:

---

interest = monthlyinterest + originalprincipal;
UpdateData (false);

---

I want interest to only show 4.34 instead of 4.34444444444444
Any Ideas?

I set the properties of the edit box to number, but that does not do the trick....

Instead using DDX_Text() on a float/double, use it on CString.
Use CString.Format() to format the float/double value the way you want (ie. "%.2f").

Thanks for the reply Codeplug,
I assume DDX_Text() referrs to the statement UpdateData ()? At least according to my book in front of me... LOL!

But I'm confused on using the CString.Format(). I don't have a reference in any of my books, do you have an example or suggestion for reference, similar to the UpdateData () for the DDX_Text();

CString::Format() uses a format specification field just like printf().
The format specification field "%.2f" will format a float/double the way you want.

Cool, I see what ya mean, I'll play around with that, I was concerned about using a conversion from double to string....
