Start or end an application on a remote computer.

Hi
how you can start or end an application on a remote computer (lan)?

[Bernhard Geyer]

Google for "Remote Execute Windows" and you find Apps from MS which can do such thinks.

Another solution is using WMI.

Zitat von Luckie:

Thanks,

I found this:

Delphi-Quellcode:

uses WbemScripting_TLB;

function remoteExecute(programName:string; machine:string=''; user:string=''; password:string=''):string;
var
  SWbemLocator1:TSWbemLocator;
  Service: ISWbemServices;
  InParam, OutParam, SObject:             ISWbemObject;
  Method:                                 ISWbemMethod;
  SProp1, SProp2, MyProperty:             ISWbemProperty;
  s,methodName:string;
  PropValue:OleVariant;
begin
  methodName:='Create';
//  CoInitialize(nil);
  SWbemLocator1:=TSWbemLocator.Create(nil);
  if machine='' then
    machine:='.';
  Service:=SWbemLocator1.ConnectServer(machine,'root\CIMV2', user, password, '','', 0, nil);
  Service.Security_.Set_ImpersonationLevel(wbemImpersonationLevelImpersonate);
  SObject:= Service.Get('Win32_Process', 0, nil);

  Method:= SOBject.Methods_.Item(methodName, 0);
  InParam:= Method.InParameters.SpawnInstance_(0);

  MyProperty:= InParam.Properties_.Add('CommandLine', wbemCimtypeString, False, 0);
  PropValue:= programName;
  MyProperty.Set_Value(PropValue);

  MyProperty:= InParam.Properties_.Add('CurrentDirectory', wbemCimtypeString, False, 0);
  PropValue:= Null;
  MyProperty.Set_Value(PropValue);

  MyProperty:= InParam.Properties_.Add('ProcessStartupInformation', wbemCimtypeObject, False, 0);
  PropValue:= Null;
  MyProperty.Set_Value(PropValue);

  OutParam:= SObject.ExecMethod_(methodName, InParam, 0, nil);
//  OutParam:= SObject.ExecMethod_(methodName, nil, 0, nil);
  SProp1:= outParam.Properties_.Item('ReturnValue', 0);
  SProp2:= outParam.Properties_.Item('ProcessId', 0);
  case SProp1.Get_Value of
    0:s:='Successful completion.';
    2:s:='Access denied.';
    3:s:='Insufficient privilege.';
    8:s:='Unknown failure.';
    9:s:='Path not found.';
   21:s:='Invalid parameter.';
   else s:='Unknown reply code!';
  end;
  SWbemLocator1.Free;
  service:=nil;
  SObject:=nil;
  OutParam:=nil;
  SProp1:=nil;
  result:=s+'(PID='+inttostr(SProp2.Get_Value)+')';
//  CoUninitialize;
end;

Run the application well, but the application not shown on the video to your PC remotely.
Which parameter should vary?
(like psexec: -i Interactive - Run the program so that it interacts with the desktop on the remote system.)
Thanks

I changed the code

Delphi-Quellcode:

....
Var
  ObjConf:             ISWbemObject;
...

...
...

  Service.Security_.Set_ImpersonationLevel(wbemImpersonationLevelImpersonate);

  // added rows
     SObject:= Service.Get('Win32_ProcessStartup',0,nil);
     ObjConf := SObject.SpawnInstance_(0);
     PropValue := 1;
     objConf.Properties_.Item('ShowWindow',0).Set_Value(PropValue);


  SObject:= Service.Get('Win32_Process', 0, nil);
...
...
  MyProperty:= InParam.Properties_.Add('ProcessStartupInformation', wbemCimtypeObject, False, 0);  
  // modified row
     PropValue:= ObjConf;
  MyProperty.Set_Value(PropValue);

but application does not appear into remote desktop PC
