问题描述
我发现了一个，但这是针对C＃的，我需要将其转换为Delphi。代码如下：
I found a code that enables System Restore monitoring, but it's for C# and I need to convert it to Delphi. Here's the code:
ManagementScope scope = new ManagementScope("\\\\localhost\\root\\default");
ManagementPath path = new ManagementPath("SystemRestore");
ObjectGetOptions options = new ObjectGetOptions();
ManagementClass process = new ManagementClass(scope, path, options);
ManagementBaseObject inParams = process.GetMethodParameters("Enable");
inParams["WaitTillEnabled"] = true;
inParams["Drive"] = osDrive;
ManagementBaseObject outParams = process.InvokeMethod("Enable", inParams, null);
有人可以帮助我将上述代码转换为Delphi吗？
Could anyone help me to convert the above code to Delphi ?
推荐答案
如果已启用对指定驱动器的监视，否则为False。作为输入 ADrive 参数，指定要监视的完整驱动器路径。当此参数是系统驱动器或空字符串时，将监视所有驱动器。此功能不会等待完全启用监视后再返回。而是在启动系统还原服务和筛选器驱动程序后立即返回：
The following function returns True if the System Restore monitoring of a specified drive has been enabled, False otherwise. As the input ADrive parameter specify the full drive path to be monitored. When this parameter is the system drive, or an empty string, all drives will be monitored. This function does not wait for monitoring to be enabled completely before it returns. Instead, it returns immediately after starting the System Restore service and filter driver:
function EnableSystemRestore(const ADrive: string): Boolean;
var
WbemObject: OleVariant;
WbemService: OleVariant;
WbemLocator: OleVariant;
begin;
Result := False;
try
WbemLocator := CreateOleObject('WbemScripting.SWbemLocator');
WbemService := WbemLocator.ConnectServer('localhost', 'root\DEFAULT');
WbemObject := WbemService.Get('SystemRestore');
Result := WbemObject.Enable(ADrive) = S_OK;
except
on E: EOleException do
ShowMessage(Format('EOleException %s %x', [E.Message, E.ErrorCode]));
on E: Exception do
ShowMessage(E.Classname + ':' + E.Message);
end;
end;
用法：
procedure TForm1.Button1Click(Sender: TObject);
begin;
if not EnableSystemRestore('D:\') then
ShowMessage('Failed!')
else
ShowMessage('Succeeded!');
end;
