c# - Handling Windows Popup like Save As, Choose File, Direct UI HWND InternetExplorer Download Strip....When System is Locked -

to handle windows popup i'd followed 3 different ways none of them works when system locked, kindly me this

with of uiautomationclient.dll,uiautomationclientsideproviders.dll,uiautomationprovider.dll,uiautomationtypes.dll

using system.windows.automation;  automationelement ieelement = automationelement.fromhandle((intptr)ieobj.hwnd);//save popup handle popups              automationelement saveelement = returnrequiredelement(ieelement, "save", "name");             if (saveelement.current.name.equals("save"))             {                 var invokepattern = saveelement.getcurrentpattern(invokepattern.pattern) invokepattern;                 invokepattern.invoke();             } 

with of inputsimulator

using windowsinput;  inputsimulator.simulatemodifiedkeystroke(virtualkeycode.menu, virtualkeycode.vk_s); 

with sendkeys

sendkeys.sendwait("^+{s}"); 

you know while running scheduler or batch process automation in system can't expect should active always, in servers
