I had some difficulty with changing the focus to the edit control when the Max chars was reached in an edit. I ended up using this code:
void CRHTC100Dlg::OnChangeId()
{
CString str;
GetDlgItemText(IDC_ID,str)
if ( str.GetLength() == 6)
NextDlgCtrl();
}//end of OnChangeId()
which works fine but it 'feels' quite bulky. Was just wondering if anyone can show me a better method of accomplishing this. The DDV_MaxChars for this control is set to 6. I attempted to move the focus when this was reached but what I got as a result was the focus changing on the input of the 7th character BUT the 7th character was placed into the next control. In the effort of continuity I need to be able to type the 6 character and then immediately move to the next control and receive any characters I typed after the 6th from the previous control (hope I didn't over-explain). Anyhow, I'd appreciate it if anyone can give me a more effective means of doing this.

Hi,
U can take a look at the following class files
1. In a subclassed edit control class I added a int member to store the max chars that edit can support
public:
int m_nMaxChars;
2. The CPP looks as
// MyEdit.cpp : implementation file
//
#include "stdafx.h"
#include "close.h"
#include "MyEdit.h"
#include "closeDlg.h"
#ifdef _DEBUG
#define new DEBUG_NEW
#undef THIS_FILE
static char THIS_FILE[] = __FILE__;
#endif
//////////////////////////
// CMyEdit
CMyEdit::CMyEdit()
{
m_nMaxChars = -1;
}
CMyEdit::~CMyEdit()
{
}
BEGIN_MESSAGE_MAP(CMyEdit,
//{{AFX_MSG_MAP(CMyEdit)
ON_CONTROL_REFLECT(EN_CHAN
//}}AFX_MSG_MAP
END_MESSAGE_MAP()
//////////////////////////
// CMyEdit message handlers
void CMyEdit::OnChange()
{
// TODO: If this is a RICHEDIT control, the control will not
// send this notification unless you override the CEdit::OnInitDialog()
// function and call CRichEditCtrl().SetEventMa
// with the ENM_CHANGE flag ORed into the mask.
// TODO: Add your control notification handler code here
if(m_nMaxChars != -1)
{
CString cStrChars;
GetWindowText(cStrChars);
if(cStrChars.GetLength() == m_nMaxChars)
{
((CCloseDlg *)GetParent())->NextDlgCtr
}
}
}
Here, Close is my app name so I have CCloseDlg class which will be parent for ur edit box.
3. Then u need to add controls to the edit boxes of type CMyEdit class. Then in OnInitDialog, set the value for that variable to have how many chars u want, like
m_ctrlEdit1.m_nMaxChars = 6;
m_ctrlEdit2.m_nMaxChars = 7;
Then run it, U will get the expected behavior.
Try it out.

What you have is fine. You could subclass the edit control (So you have a generic class if you need to use this concept on multiple edit controls).
1 small shortcut.
void CRHTC100Dlg::OnChangeId()
{
if (GetDlgItem(IDC_ID)->GetWi
{
NextDlgCtrl();
}
}
Regards.
