Do you mean you have 2 edit boxes and a combo box? And you want to take the characters of a string in one of the edit boxes when you click on the combo box and then display them in the second edit box!!?? Why would you program somethink like that

Anyway.... I will just consider you meant "button" , not "combo".
So, let's call the 2 associated CString variables m_inputEditBox and m_OutputEditBox. Also, please add a member variable called pos, that we will use in order to know where in the string we are.
Add this line in your OnInitDialog:

CPP / C++ / C Code:

	pos = 0;

Then, in your OnClick method:

CPP / C++ / C Code:

void CSampleDlg::OnButton1() 
{
	UpdateData(TRUE);
	if ( pos < m_inputEditBox.GetLength() )
	{
		m_OutputEditBox.Insert(m_OutputEditBox.GetLength(), m_inputEditBox.GetAt(pos++));
		UpdateData(FALSE);
	}
}

Voila!

If this isn't what you wanted to do (and chances are it's not), pls. let me know and also pls. provide some (clear) specifications.

Kind regards,
Luci

Hi,
Thks 4 ur help.
I've to write characters to the port.
While reading from the port only i've to do those operation(ie: for each click of a button, read character by character from the port).
How is it possible.
What codings i've to do?

This is correct?

CPP / C++ / C Code:

if ( pos < m_cssendchar.GetLength() )
{
	UpdateData();
	m_csreceivechar.Insert(m_cssendchar.GetLength(), m_csreceivechar.GetAt(pos++));
	port.ReadByte(m_csreceivechar);

I am really lost...

CPP / C++ / C Code:

m_csreceivechar.Insert(m_cssendchar.GetLength(), m_csreceivechar.GetAt(pos++));

What is wrong here? Well, you are working with m_csreceivechar *ONLY*. You are putting characters from m_csreceivechar into m_csreceivechar!!!

Maybe this is what you are trying to do?

CPP / C++ / C Code:

m_cssendchar.Insert(m_cssendchar.GetLength(), m_csreceivechar.GetAt(pos++));

Why are you asking me if your code is correct? Does it do what you want it to do?

Please don't take this to hard, I'm not trying to scare you or anything... I am really trying to help, but you must understand your logic is NOT clear for me at all.
Please try concentrating on this problem, and I'm sure you will be able to get it right! I will answer any questions you might still have - but please concentrate, OK?

Kind regards,
Luci
