Add a message handler for the button 'OnClick' message. Inside it, get the data from the first edit control and put it into the second one...

u mean like this

void CSerialcommDlg::Onsend()
{
CString str;
EDIT1.GetWindowText(str);
edit2.SetWindowText(str);

}

but i got this error:
C:\Testing Area\serialcomm\serialcommDlg.cpp(190) : error C2065: 'EDIT1' : undeclared identifier
C:\Testing Area\serialcomm\serialcommDlg.cpp(190) : error C2228: left of '.GetWindowTextA' must have class/struct/union type
C:\Testing Area\serialcomm\serialcommDlg.cpp(191) : error C2065: 'edit2' : undeclared identifier
C:\Testing Area\serialcomm\serialcommDlg.cpp(191) : error C2228: left of '.SetWindowTextA' must have class/struct/union type

You must associate your edit controls with variables edit1 and edit2. Use classwizard for this.

take this approach:

open your Dialog template, CTRL+W, tab member variables and add member vars (category value, type CString) for your edit boxes

lets say m_ctrlEdit1 and m_ctrlEdit2

in OnSend:

Code:

UpdateData(true); //writes text in editboxes to memebr vars m_ctrlEdit2 = m_ctrlEdit1; UpdateData(false); //write text in member vars to edit boxes

if you want to use this code
EDIT1 and edit2 have to be member variables of category control type CEdit

Well...one correction...never mix the standard type 'bool' with the Microsoft define 'BOOL'...thus...

Code:

UpdateData(TRUE); //writes text in editboxes to memebr vars m_ctrlEdit2 = m_ctrlEdit1; UpdateData(FALSE); //write text in member vars to edit boxes

My suggestion to you if you have to ask this question, is to get a good tutorial book on programming with MFC and work through it. I don't mean to this sound condecending, but What you're asking is rudimentary MFC coding. It sound like you may be a little ahead of yourself at this point. Work through a tutorial to get a handle on the basics, then some of this stuff will make sense. Untill you do that, I'm not sure any answers you recieve here will make sense to you.
