<br />
class CMyEdit:public CEdit<br />
<br />
void CMyEdit::OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags)<br />
{<br />
    CEdit::OnKeyDown(nChar, nRepCnt, nFlags); // though called first<br />
    CString s;<br />
    GetWindowText(s);//But s is the previous WindowText<br />
}<br />

I want to use the WindowText as soon as the text is changed, any way?

Thanks.

in the cpp file write
BEGIN_MESSAGE_MAP(CYourEdit, CEdit)
ON_NOTIFY_REFLECT(EN_CHANGE, OnEnChange)
END_MESSAGE_MAP()
afx_msg void OnEnChange(NMHDR *pNMHDR , LRESULT *pResult);
void CYourEdit::OnEnChange(NMHDR *pNMHDR , LRESULT *pResult)
{
CEdit::GetWindowText(str);
//Then use the str to do your work
}

hi how to convert tchar to const char

It will not be perfect, because tchar may have 2 bytes or 1 byte,
you can't put 2 byte into 1 byte when converting,
however it may work when tchar takes 1 byte. All depends on your code, you can try it.

<br />
TCHAR t;<br />
const char c=char(t);<br />

<br />
TCHAR t;<br />
const char *pc=cosnt char*(&t);<br />

TCHAR is a macro that resolves either to char if UNICODE is not defined (then it will be 1 byte) or to wchar if UNICODE is defined (then it will be 2 bytes).

I'm looking for some sample code to see how to build an custom IE toolbar extension. I'm working on a pet project to allow an IE toolbar to interact with form data similar to how the google toolbar works. I've tried searching code project using these terms: "ie addin" "ie toolbar" "addin" but I haven't seen anything yet. Your help is appreciated.
