Reading in from a dialog box

[o.fithcheallaigh]

Hello,

Thanks for the reply. I have tried a different approach, but got a new issue. Hopefully someone can help.

Here is the code

{
	CString myEdit1;
	char a;
	int i;
	const int KEY = 23;	
	this -> GetDlgItemText(IDC_EDIT1, myEdit1);
	int length = myEdit1.GetLength();
	char *p = myEdit1.GetBuffer();

	for (i = 0; i < length; i++)
	{
		*(p + i) = (*(p + i) ^ KEY);
	}
	a = (char)*(p+1);

	SetDlgItemText(IDC_EDIT2, a);
}

And I am getting an error "error C2664: 'CWnd::SetDlgItemTextA' : cannot convert parameter 2 from 'char' to 'LPCTSTR' ...Conversion from integral type to pointer type requires reinterpret_cast, C-style cast or function-style cast"

I am not sure how to sort this out. Hopefully someone can help.

Thanks in advance.
