NameDescription
System_CAPS_pubmethodUIPermission(PermissionState)

Initializes a new instance of the UIPermission class with either fully restricted or unrestricted access, as specified.

System_CAPS_pubmethodUIPermission(UIPermissionClipboard)

Initializes a new instance of the UIPermission class with the permissions for the Clipboard, and no access to windows.

System_CAPS_pubmethodUIPermission(UIPermissionWindow)

Initializes a new instance of the UIPermission class with the permissions for windows, and no access to the Clipboard.

System_CAPS_pubmethodUIPermission(UIPermissionWindow, UIPermissionClipboard)

Initializes a new instance of the UIPermission class with the specified permissions for windows and the Clipboard.

NameDescription
System_CAPS_pubpropertyClipboard

Gets or sets the Clipboard access represented by the permission.

System_CAPS_pubpropertyWindow

Gets or sets the window access represented by the permission.

NameDescription
System_CAPS_pubmethodAssert()

Declares that the calling code can access the resource protected by a permission demand through the code that calls this method, even if callers higher in the stack have not been granted permission to access the resource. Using Assert can create security issues.(Inherited from CodeAccessPermission.)

System_CAPS_pubmethodCopy()

Creates and returns an identical copy of the current permission.(Overrides CodeAccessPermission.Copy().)

System_CAPS_pubmethodDemand()

Forces a SecurityException at run time if all callers higher in the call stack have not been granted the permission specified by the current instance.(Inherited from CodeAccessPermission.)

System_CAPS_pubmethodDeny()

Obsolete.Prevents callers higher in the call stack from using the code that calls this method to access the resource specified by the current instance.(Inherited from CodeAccessPermission.)

System_CAPS_pubmethodEquals(Object)

Determines whether the specified CodeAccessPermission object is equal to the current CodeAccessPermission.(Inherited from CodeAccessPermission.)

System_CAPS_pubmethodFromXml(SecurityElement)

Reconstructs a permission with a specified state from an XML encoding.(Overrides CodeAccessPermission.FromXml(SecurityElement).)

System_CAPS_pubmethodGetHashCode()

Gets a hash code for the CodeAccessPermission object that is suitable for use in hashing algorithms and data structures such as a hash table.(Inherited from CodeAccessPermission.)

System_CAPS_pubmethodGetType()

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_pubmethodIntersect(IPermission)

Creates and returns a permission that is the intersection of the current permission and the specified permission.(Overrides CodeAccessPermission.Intersect(IPermission).)

System_CAPS_pubmethodIsSubsetOf(IPermission)

Determines whether the current permission is a subset of the specified permission.(Overrides CodeAccessPermission.IsSubsetOf(IPermission).)

System_CAPS_pubmethodIsUnrestricted()

Returns a value indicating whether the current permission is unrestricted.

System_CAPS_pubmethodPermitOnly()

Prevents callers higher in the call stack from using the code that calls this method to access all resources except for the resource specified by the current instance.(Inherited from CodeAccessPermission.)

System_CAPS_pubmethodToString()

Creates and returns a string representation of the current permission object.(Inherited from CodeAccessPermission.)

System_CAPS_pubmethodToXml()

Creates an XML encoding of the permission and its current state.(Overrides CodeAccessPermission.ToXml().)

System_CAPS_pubmethodUnion(IPermission)

Creates a permission that is the union of the permission and the specified permission.(Overrides CodeAccessPermission.Union(IPermission).)

Drawing and user input events in windows are user interfaces.

The permission to use windows can be one of the following: unrestricted, limited to SafeTopLevelWindows, only SafeSubWindows, or no window drawing or user input event access allowed. SafeTopLevelWindows and SafeSubWindows are restricted in title and size to prevent possible spoofing by potentially harmful code.

The permission to use the Clipboard can be one of the following: unrestricted, write-only, or no Clipboard access allowed. The paste limitation prevents potentially harmful applications from taking data from the Clipboard without the user's consent, while still allowing the cut, copy, and paste operations when initiated by the user through keyboard commands.
