Detailed Description

Presentation password protection management.

Member Function Documentation

◆ CheckWriteProtection()

bool Aspose::Slides::ProtectionManager::CheckWriteProtection ( System::String password )

overridevirtual

Determines whether a presentation is a password protected to modify.

auto presentation = System::MakeObject<Presentation>(presentationFilePath);

bool isWriteProtected = presentation->get_ProtectionManager()->CheckWriteProtection(u"my_password");

Parameters

password The password for checking.

Returns: True if the password is valid; otherwise, false.

You should check the ProtectionManager::get_IsWriteProtected property before calling this method.
When the password is null or empty, this method returns false.

Implements Aspose::Slides::IProtectionManager.

◆ Encrypt()

void Aspose::Slides::ProtectionManager::Encrypt ( System::String encryptionPassword )

overridevirtual

Encrypts Presentation with specified password.

Parameters

encryptionPassword The password.

The following sample code shows you how to encrypt a PowerPoint Presentation.

auto presentation = System::MakeObject<Presentation>(u"pres.pptx");
presentation->get_ProtectionManager()->Encrypt(u"123123");
presentation->Save(u"encrypted-pres.pptx", SaveFormat::Pptx);

Implements Aspose::Slides::IProtectionManager.

◆ get_EncryptDocumentProperties()

bool Aspose::Slides::ProtectionManager::get_EncryptDocumentProperties ( )

overridevirtual

This property makes sense, if presentation is password protected. If true then document properties is encrypted in presentation file. If false then document properties is public while presentation is encrypted. Read bool.

Implements Aspose::Slides::IProtectionManager.

◆ get_EncryptionPassword()

◆ get_IsEncrypted()

bool Aspose::Slides::ProtectionManager::get_IsEncrypted ( )

overridevirtual

Gets a value indicating whether this instance is encrypted. Read-only bool.

true if presentation was loaded from encrypted file or Encrypt(String) method was called ; otherwise, false.

Implements Aspose::Slides::IProtectionManager.

◆ get_IsOnlyDocumentPropertiesLoaded()

bool Aspose::Slides::ProtectionManager::get_IsOnlyDocumentPropertiesLoaded ( )

overridevirtual

This property makes sense, if presentation file is password protected and document properties of this file are public. Value of true means that only document properties are loaded from an encrypted presentation file without use of password. Value of false means that entire encrypted presentation is loaded with use of right password, not only document properties are loaded. If presentation isn't encrypted then property value is always false. If document properties of an encrypted file aren't public then property value is always false. If Presentation.EncryptDocumentProperties is true than IsOnlyDocumentPropertiesLoaded property value is always false. Read-only bool.

Implements Aspose::Slides::IProtectionManager.

◆ get_IsWriteProtected()

bool Aspose::Slides::ProtectionManager::get_IsWriteProtected ( )

overridevirtual

Gets a value indicating whether this presentation is write protected. Read-only bool.

Implements Aspose::Slides::IProtectionManager.

◆ get_ReadOnlyRecommended()

bool Aspose::Slides::ProtectionManager::get_ReadOnlyRecommended ( )

overridevirtual

Gets read-only recommendation. Read bool.

auto pres = System::MakeObject<Presentation>();
pres->get_ProtectionManager()->set_ReadOnlyRecommended(true);
pres->Save(u"ReadOnlyPresentation.pptx", SaveFormat::Pptx);

Implements Aspose::Slides::IProtectionManager.

◆ RemoveEncryption()

void Aspose::Slides::ProtectionManager::RemoveEncryption ( )

overridevirtual

Removes the encryption.

Implements Aspose::Slides::IProtectionManager.

◆ RemoveWriteProtection()

void Aspose::Slides::ProtectionManager::RemoveWriteProtection ( )

overridevirtual

Removes write protection for this presentation.

This sample code shows you how to remove the write protection from a PowerPoint Presentation.

auto presentation = System::MakeObject<Presentation>(u"pres.pptx");
presentation->get_ProtectionManager()->RemoveWriteProtection();
presentation->Save(u"write-protection-removed.pptx", SaveFormat::Pptx);

Implements Aspose::Slides::IProtectionManager.

◆ set_EncryptDocumentProperties()

void Aspose::Slides::ProtectionManager::set_EncryptDocumentProperties ( bool value )

overridevirtual

This property makes sense, if presentation is password protected. If true then document properties is encrypted in presentation file. If false then document properties is public while presentation is encrypted. Write bool.

Implements Aspose::Slides::IProtectionManager.

◆ set_ReadOnlyRecommended()

void Aspose::Slides::ProtectionManager::set_ReadOnlyRecommended ( bool value )

overridevirtual

Sets read-only recommendation. Write bool.

The following sample code shows you how to set a PowerPoint Presentation to Read-Only in C# using Aspose.Slides.

auto pres = System::MakeObject<Presentation>();
pres->get_ProtectionManager()->set_ReadOnlyRecommended(true);
pres->Save(u"ReadOnlyPresentation.pptx", SaveFormat::Pptx);

Implements Aspose::Slides::IProtectionManager.

◆ SetWriteProtection()

void Aspose::Slides::ProtectionManager::SetWriteProtection ( System::String password )

overridevirtual

Set write protection for this presentation with specified password.

Parameters

password The password.

The following sample code shows you how to set a write protection to a presentation.

auto presentation = System::MakeObject<Presentation>(u"pres.pptx");
presentation->get_ProtectionManager()->SetWriteProtection(u"123123");
presentation->Save(u"write-protected-pres.pptx", SaveFormat::Pptx);

Implements Aspose::Slides::IProtectionManager.
