How can i do that ? lets say in list i have 44.22+44.22 the result must be in csText 88.44 HOW can i do that? int nSum = 0; int uSum = 0; for( int nRow = 0; nRow < m_list1.GetItemCount();nRow++) { if(m_list1.GetCheck(/*index of item*/nRow)) { csText = m_list1.GetItemText( nRow, 2 ); uSum += atoi( csText); csText.Format("%.2f",uSum); m_sum.SetWindowText(csText); } } this code give the result : lets say i have in list 44.22+44.22 the result in csText is 88.00 but i need 88.44 HOW ?

don't use atoi(). instead use atof() I think you must read the documentation rather than starting to build on the project. atoi converts a string to int and not to a float and then when you add them it returns an int in uSum which is just printed as a float value.
Somethings seem HARD to do, until we know how to do them. ;-)_AnShUmAn_

ok but... : uSum += atof( csText); warning C4244: '+=' : conversion from 'double' to 'int', possible loss of data Why?

because nSum has data type int. :)

uSum is an int. so you would need to use typecasting or declare uSum as a float. I think you are missing on the basics. :|

It would be better if you read some tutorials on typecasting, using variables and reading some more basics and some more............................and a few more....................:rolleyes:

You declare an integer, how would you expect to store a floating point value into it and expect that it still holds a floating point value ? I think you REALLY need to find some good book about the basics of C++. I mean, knowing what an integer and a double are, is at least the bare minimum. It's the thing you learn at very very begining.

no, you forget the prerequisite step : learn C++ :doh: this guy is f*cking too lazy and keeps asking since months now dumb questions

WTF !!! can't you understand the error message ??????

**to 'int'**, possible loss of datato int mean you're writing in an int ! you know what ? go by a C/C++ book and learn that language biefore trying to use it any further (or swith to VB :zzz: )

How can i make this : i have this code : csText.Format("%d", nSum); ok but my result is lets say 44,ok but if i have 22.3+22.3=44.6(nSum) this is not working : csText.Format("%d", nSum); How can i make this?(to have the result whit 44.6 lets say not 44)

Thats the tricky part :suss:. If the things remain the same even after learning :laugh:. That could be the reason he isn't trying that.

What do you mean with the generic is not working? :confused: Please detail the misbehaviour (i.e. obtained result vs expected result). BTW Have you correctly declared
nSumas floating point number? :)If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler. -- Alfonso the Wise, 13th Century King of Castile.

I don't know why, but this guys is really starting to piss me off. I spent almost an hour writing my response to him a few threads down, assuming he was at least semi-capable as a C++ programmer.

Is there anything that doesn't, John? How people can get so riled over stuff like this is beyond me. If he bothers you so, why not just ignore him and move on?
