KeyContainer VB.NET WinRT Reference Documentation
Represents a key container on a Windows operating system. Each Windows system has a "machine keyset" where named key containers are potentially accessible to all processes. The "machine keyset" is a machine-wide container for key containers. Each user account also has it's own set of key containers. Therefore, when you open or create a key container by name, you must also indicate whether it's the "machine keyset" or the user account's keyset.
The KeyContainer object provides methods opening, creating, and deleting key containers by name. It also provides the ability to import public/private keys into a key container, or to export public/private keys from a key container. It can generate new key pairs. It can also enumerate the names of existing key containers.
This class is specific to the Windows operating system, and therefore is only available on Windows systems.
Dim obj As New Chilkat.KeyContainer()
DebugLogFilePath As String
If set to a file path, causes each Chilkat method or property call to automatically append it's LastErrorText to the specified log file. The information is appended such that if a hang or crash occurs, it is possible to see the context in which the problem occurred, as well as a history of all Chilkat calls up to the point of the problem. The VerboseLogging property can be set to provide more detailed information.
This property is typically used for debugging the rare cases where a Chilkat method call hangs or generates an exception that halts program execution (i.e. crashes).
A hang or crash should generally never happen. The typical causes of a hang are:
- a timeout related property was set to 0 to explicitly indicate that an infinite timeout is desired,
- the hang is actually a hang within an event callback (i.e. it is a hang within the application code), or
- there is an internal problem (bug) in the Chilkat code that causes the hang.
LastErrorHtml As String (ReadOnly)
Provides information in HTML format about the last method/property called. If a method call returns a value indicating failure, or behaves unexpectedly, examine this property to get more information.
LastErrorText As String (ReadOnly)
Provides information in plain-text format about the last method/property called. If a method call returns a value indicating failure, or behaves unexpectedly, examine this property to get more information.
LastErrorXml As String (ReadOnly)
Provides information in XML format about the last method/property called. If a method call returns a value indicating failure, or behaves unexpectedly, examine this property to get more information.
LastMethodSuccess As Boolean
Introduced in version 220.127.116.11
Indicate whether the last method call succeeded or failed. A value of True indicates success, a value of False indicates failure. This property is automatically set for method calls. It is not modified by property accesses. The property is automatically set to indicate success for the following types of method calls:
- Any method that returns a string.
- Any method returning a Chilkat object, binary bytes, or a date/time.
- Any method returning a standard boolean status value where success = True and failure = False.
- Any method returning an integer where failure is defined by a return value less than zero.
Note: Methods that do not fit the above requirements will always set this property equal to True. For example, a method that returns no value (such as a "void" in C++) will technically always succeed.
VerboseLogging As Boolean
If set to True, then the contents of LastErrorText (or LastErrorXml, or LastErrorHtml) may contain more verbose information. The default value is False. Verbose logging should only be used for debugging. The potentially large quantity of logged information may adversely affect peformance.
Version As String (ReadOnly)
Version of the component/library, such as "18.104.22.168"
Function SaveLastError(ByVal path As String) As Boolean
Saves the last-error information (the contents of LastErrorXml) to an XML formatted file.
Returns True for success, False for failure.
