推荐答案

通过设置插入来执行使用 SetSel（）将位置索引作为起点和终点传递，并用调用 ReplaceSel（）。要附加文本，请将-1作为位置索引传递。要设置完整文本（全部替换），请使用 SetWindowText（）。





Inserting is performed by setting the position with SetSel() passing the position index as start and end point and replacing the (empty) selection with the text calling ReplaceSel(). To append text, pass -1 as position index. To set the complete text (replace all), use SetWindowText().

// Insert text at specified position using a CEdit derived class
void CMyEdit::InsertText(int nPos, LPCTSTR lpszText)
{
    SetSel(nPos, nPos);
    ReplaceSel(lpszText);
}

// Insert text at specified position of a CEdit control that is a member of a dialog
void CMyDialog::InsertEditText(int nPos, LPCTSTR lpszText)
{
    m_edit.SetSel(nPos, nPos);
    m_edit.ReplaceSel(lpszText);
}

// Insert text at specified position of a CEdit inside a dialog using the resource ID
void CMyDialog::InsertText(int nID, int nPos, LPCTSTR lpszText)
{
    CEdit *pEdit = (CEdit *)GetDlgItem(nID);
    pEdit->SetSel(nPos, nPos);
    pEdit->ReplaceSel(lpszText);
}
