MFC CListCtrl

列名、行内容的添加、删除。

据列名、行内容长度设置列宽。

排序。

 

提升权限

BOOL CDemoListCtrlApp::EnableDebugPrivilege()
{  HANDLE token;  if(!OpenProcessToken(GetCurrentProcess(),TOKEN_ADJUST_PRIVILEGES,&token))  {  return FALSE;  }  TOKEN_PRIVILEGES tkp;  tkp.PrivilegeCount = 1;  ::LookupPrivilegeValue(NULL,SE_DEBUG_NAME,&tkp.Privileges[0].Luid);  tkp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;  if(!AdjustTokenPrivileges(token,FALSE,&tkp,sizeof(tkp),NULL,NULL))  {  return FALSE;  }  CloseHandle(token);  return TRUE;  
} 

 

取进程全路径

右键显示菜单

void CDemoListCtrlDlg::OnNMRClickList1(NMHDR *pNMHDR, LRESULT *pResult)
{LPNMITEMACTIVATE pNMItemActivate = reinterpret_cast<LPNMITEMACTIVATE>(pNMHDR);//弹出菜单
    CPoint pos;if (GetCursorPos(&pos)){CMenu menu;//加载菜单资源
        menu.LoadMenu(IDR_MENU1);//目标子菜单是菜单资源第0列menu.GetSubMenu(0)->TrackPopupMenu(TPM_RIGHTBUTTON, pos.x, pos.y, this);}*pResult = 0;
}

 

右键菜单：刷新

添加菜单资源

xxxDlg.h

class CDemoListCtrlDlg : public CDialog
{
//...public:afx_msg void OnRefreshList1();   
}

xxxDlg.cpp

BEGIN_MESSAGE_MAP(CDemoListCtrlDlg, CDialog)
//...
    ON_COMMAND(ID_REFRESHLIST1, OnRefreshList1)
END_MESSAGE_MAP()void CDemoListCtrlDlg::OnRefreshList1()
{ShowProcess(m_listctrl);
