定義
重要
部分資訊涉及發行前產品,在發行之前可能會有大幅修改。 Microsoft 對此處提供的資訊,不做任何明確或隱含的瑕疵擔保。
取得或設定值,表示是否公開外部處理序管理。
public:
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
屬性值
如果公開外部處理序管理,則為 true
,否則為 false
。 預設為 false
。
範例
下列程式代碼範例說明搭配 屬性ExternalProcessMgmt使用 HostProtectionAttribute 屬性。 這個範例是提供給 類別之較大範例的 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

公開外部進程管理的程式代碼可能會建立或終結其他進程。
