请问如何编代码调出软键盘

Question

1、打开/关闭输入法 
    void CHideDlgDlg::OnButton9() 
    { 
     // TODO: Add your control notification handler code here 
     CWnd * pWnd = GetDlgItem(IDC_TREE1); 
     if (pWnd){ 
     pWnd->SetFocus(); 
     ImmSimulateHotKey(pWnd->m_hWnd, IME_CHOTKEY_IME_NONIME_TOGGLE); 
     
     HIMC hIMC = ImmGetContext(pWnd->m_hWnd); 
     DWORD dwConv, dwSent; 
     DWORD dwTemp; 
     
     ImmGetConversionStatus(hIMC,&dwConv,&dwSent); 
     dwConv |= IME_CMODE_SOFTKBD; 
     
     ImmSetConversionStatus(hIMC,dwConv,dwSent); 
     
     ImmReleaseContext(pWnd->m_hWnd,hIMC); 
     } 
     
    } 
    2、打开/关闭软键盘 
    void CHideDlgDlg::OnButton10() 
    { 
     // TODO: Add your control notification handler code here 
     CWnd * pWnd = GetDlgItem(IDC_TREE1); 
     if (pWnd){ 
     pWnd->SetFocus(); 
     
     HIMC hIMC = ImmGetContext(pWnd->m_hWnd); 
     DWORD dwConv, dwSent; 
     DWORD dwTemp; 
     
     ImmGetConversionStatus(hIMC,&dwConv,&dwSent); 
     if (dwConv & IME_CMODE_SOFTKBD) 
     dwConv &= ~IME_CMODE_SOFTKBD; 
     else 
     dwConv |= IME_CMODE_SOFTKBD; 
     
     ImmSetConversionStatus(hIMC,dwConv,dwSent); 
     
     ImmReleaseContext(pWnd->m_hWnd,hIMC); 
     } 
    } 以上是C代码
