      hey, guy, try this... :) ... char szA[100], szB[100], szC[200]; int c; printf(szA,"%d",a); //here, a is a int number entered on edit box 1. printf(szB,"%d",b); //here, b is a int number entered on edit box 2. strcpy(szC,szA); strcat(szC,szB); c = atoi(szC); //here, c is the int number you want, just place it into edit box 3 ... hope this helps! ;)

What is char szA[100], szB[100], szC[200];? Should I use Cstring for BOX3?

          How "it doesn't work for you"? what error occurred? szA,szB,szC just are temporary char string variables.

Never mind string concatenation, read up about variable declaration first. Let us walk before we run.

                    oh, god...:) just attach a CString class variable with your edit box 3, and then make it equal to "szC", and then call UpdateData(FALSE) to make it show in edit box 3... ;P

                      and, you can also... attach a int variable with your edit box 3, and then make it equal to c, and then call UpdateData(FALSE) to make it show in edit box 3...
