Try this function: void RoundString(CString& str) { float fVal = 0; swscanf_s(str, L"%f", &fVal); int nTemp = (int)((fVal + 0.005)*100); fVal = (float)((float)nTemp/100); str.Format(L"%.4f", fVal); }

He gave you an example! :rolleyes:

The function I gave you receives a CString object by reference, puts the value into a float variable, rounds it to 2 numbers after the decimal point and converts the new (rounded) value back into the CString object.

More simple than a copy/paste ?? :confused:

That's two operations, Cedric. Can't you trim it down to one? Quit making folks work so hard.

you idiot. someone gives you a function you just have top copy/paste in your code and call, but always you complain. :suss:

copy/paste == 2 ...processing reduction... shoot in the ass == 1 reduction performed successfully :jig:

your example will compile only if UNICODE is defined... you should use _T(), stscanf() and so on...

ok ! i understand you but you don t understand ME ! Le t say if someoane say : " You are not so smart if you use 6 lines of code for this ! " All i want is to find a way to make this function more simple , because he use to mutch code for this function ! for this function !? think about it its just ROUND ! make this : 16.0697 to 16.0700 to use sutch code!? the code is fine but no one say its wrong! i remind you i have CDialog base aplication, i have for ex: m_edit CEdit; m_edit2 CEdit; i must use for ex: OnChange m_edit; CString sT1,sT2; m_edit.GetWindowText(sT1); ... ... ... m_edit2.SetWindowText(sT2);

It is almost certainly possible to write your function in one line - but the advice that you are getting from professional programmers here is not to do that. What it does will be the same, the syntax just more complex. If this is not simple enough for you, find a better way. Before you complain about the solution someone has bothered to give you, engage brain and think of what is involved (having one solution in front of you should help). In this case the simplest way I can see to round the contents of one edit box is to get the string, convert to a floating point representation, round and convert back to a string. If you can find a better way, we have shared one solution with you, please share yours with us.
