property bool ExternalProcessMgmt { bool get(); void set(bool value); };
public bool ExternalProcessMgmt { get; set; }
member this.ExternalProcessMgmt : bool with get, set
Public Property ExternalProcessMgmt As Boolean
属性值
如果公开外部进程管理,则为 true
,否则为 false
。 默认值为 false
。
示例
下面的代码示例演示如何将 特性与 属性一 HostProtectionAttribute 起使用 ExternalProcessMgmt 。 此示例是为 类提供的更大示例的 HostProtectionAttribute 一部分。
// The following class is an example of code that exposes external process management.
// Add the LicenseProviderAttribute to the control.
[LicenseProvider(LicFileLicenseProvider::typeid)]
public ref class MyControl: public System::Windows::Forms::Control
{
private:
// Create a new, null license.
License^ license;
public:
[HostProtection(ExternalProcessMgmt=true)]
MyControl()
{
license = nullptr;
// Determine if a valid license can be granted.
bool isValid = LicenseManager::IsValid( MyControl::typeid );
Console::WriteLine( "The result of the IsValid method call is {0}", isValid );
}
};
// The following class is an example of code that exposes
// external process management.
// Add the LicenseProviderAttribute to the control.
[LicenseProvider (typeof(LicFileLicenseProvider))]
public class MyControl : System.Windows.Forms.Control
{
// Create a new, null license.
private License license = null;
[HostProtection (ExternalProcessMgmt = true)]
public MyControl ()
{
// Determine if a valid license can be granted.
bool isValid = LicenseManager.IsValid (typeof(MyControl));
Console.WriteLine ("The result of the IsValid method call is " +
isValid.ToString ());
}
protected override void Dispose (bool disposing)
{
if (disposing)
{
if (license != null)
{
license.Dispose ();
license = null;
}
}
}
}
' The following class is an example of code that exposes
' external process management.
' Add the LicenseProviderAttribute to the control.
<LicenseProvider(GetType(LicFileLicenseProvider))> _
Public Class MyControl
Inherits System.Windows.Forms.Control
' Create a new, null license.
Private license As License = Nothing
<HostProtectionAttribute(ExternalProcessMgmt := True)> _
Public Sub New()
' Determine if a valid license can be granted.
Dim isValid As Boolean = LicenseManager.IsValid(GetType(MyControl))
Console.WriteLine(("The result of the IsValid method call is " & _
isValid.ToString()))
End Sub
Protected Overrides Sub Dispose(ByVal disposing As Boolean)
If disposing Then
If Not (license Is Nothing) Then
license.Dispose()
license = Nothing
End If
End If
End Sub
End Class
注解
公开外部进程管理的代码可能会创建或销毁其他进程。
