Properties

AccessToken
void get_AccessToken(CkString &str);
const wchar_t *accessToken(void);
void put_AccessToken(const wchar_t *str);
Introduced in version 9.5.0.58

The access token to be used in Azure AD REST API requests. This property is set on a successful call to ObtainAccessToken.

More Information and Examples
top
ClientId
void get_ClientId(CkString &str);
const wchar_t *clientId(void);
void put_ClientId(const wchar_t *str);
Introduced in version 9.5.0.58

Specifies the Azure AD client id of the calling web service. To find the calling application's client ID, in the Azure Management Portal, click Active Directory, click the directory, click the application, and then click Configure.

top
ClientSecret
void get_ClientSecret(CkString &str);
const wchar_t *clientSecret(void);
void put_ClientSecret(const wchar_t *str);
Introduced in version 9.5.0.58

A key registered for the calling web service in Azure AD. To create a key, in the Azure Management Portal, click Active Directory, click the directory, click the application, and then click Configure.

top
DebugLogFilePath
void get_DebugLogFilePath(CkString &str);
const wchar_t *debugLogFilePath(void);
void put_DebugLogFilePath(const wchar_t *str);

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:

  1. a timeout related property was set to 0 to explicitly indicate that an infinite timeout is desired,
  2. the hang is actually a hang within an event callback (i.e. it is a hang within the application code), or
  3. there is an internal problem (bug) in the Chilkat code that causes the hang.

top
LastErrorHtml
void get_LastErrorHtml(CkString &str);
const wchar_t *lastErrorHtml(void);

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.

top
LastErrorText
void get_LastErrorText(CkString &str);
const wchar_t *lastErrorText(void);

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.

top
LastErrorXml
void get_LastErrorXml(CkString &str);
const wchar_t *lastErrorXml(void);

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.

top
LastMethodSuccess
bool get_LastMethodSuccess(void);
void put_LastMethodSuccess(bool newVal);
Introduced in version 9.5.0.52

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.

top
NumSecondsRemaining
int get_NumSecondsRemaining(void);
Introduced in version 9.5.0.58

If the access token is valid, contains the number of seconds remaining until it expires. A value of 0 indicates an invalid or expired access token.

top
Resource
void get_Resource(CkString &str);
const wchar_t *resource(void);
void put_Resource(const wchar_t *str);
Introduced in version 9.5.0.58

The App ID URI of the receiving web service. To find the App ID URI, in the Azure Management Portal, click Active Directory, click the directory, click the application, and then click Configure.

top
TenantId
void get_TenantId(CkString &str);
const wchar_t *tenantId(void);
void put_TenantId(const wchar_t *str);
Introduced in version 9.5.0.58

true if the AccessToken property contains a valid non-expired access token obtained via the call to ObtainAccessToken.

top
Valid
bool get_Valid(void);
Introduced in version 9.5.0.58

true if the AccessToken property contains a valid non-expired access token obtained via the call to ObtainAccessToken.

top
VerboseLogging
bool get_VerboseLogging(void);
void put_VerboseLogging(bool newVal);

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.

top
Version
void get_Version(CkString &str);
const wchar_t *version(void);

Version of the component/library, such as "9.5.0.63"

top

Methods

ObtainAccessToken
bool ObtainAccessToken(CkSocketW &connection);
Introduced in version 9.5.0.58

Sends the HTTP request to fetch the access token. When this method completes successfully, the access token is available in the AccessToken property. The connection is an existing connection to login.microsoftonline.com.

Returns true for success, false for failure.

More Information and Examples
top
ObtainAccessTokenAsync (1)
CkTaskW *ObtainAccessTokenAsync(CkSocketW &connection);
Introduced in version 9.5.0.58

Creates an asynchronous task to call the ObtainAccessToken method with the arguments provided. (Async methods are available starting in Chilkat v9.5.0.52.)

Note: Async method event callbacks happen in the background thread. Accessing and updating UI elements existing in the main thread may require special considerations.

Note: The application is responsible for deleting (via the C++ delete operator) the object returned by this method.

Returns NULL on failure

top
SaveLastError
bool SaveLastError(const wchar_t *path);

Saves the last-error information (the contents of LastErrorXml) to an XML formatted file.

Returns true for success, false for failure.

top

Events

To implement an event callback, your application would define and implement a class that inherits from CkBaseProgressW. Your application can implement methods to override some or all of the default/empty method implementations of the CkBaseProgressW base class.

For example:

  CkAuthAzureADW authazuread;

  MyAuthAzureADProgressW callbackObj;

  authazuread.put_EventCallbackObject(&callbackObj);

MyAuthAzureADProgressW example:

#include "CkBaseProgressW.h"

class MyAuthAzureADProgressW : public CkBaseProgressW {

  public:
    MyAuthAzureADProgressW();
    virtual ~MyAuthAzureADProgressW();

    void AbortCheck(bool  *abort);

    void BinaryData(const unsigned char *data, unsigned int length);

    void PercentDone(int pctDone, bool  *abort);

    void ProgressInfo(const wchar_t *name, const wchar_t *value);

    void TaskCompleted(CkTaskW &task);

    void TextData(const wchar_t *data);

};
AbortCheck
void AbortCheck(bool *abort);

Provides the opportunity for a method call to be aborted. The AbortCheck event is fired periodically based on the value of the HeartbeatMs property. If HeartbeatMs is 0, then no AbortCheck events will fire. As an example, to fire 5 AbortCheck events per second, set the HeartbeatMs property equal to 200.

top
PercentDone
void PercentDone(int pctDone, bool *abort);

Provides the percentage completed for any method that involves network communications or time-consuming processing (assuming it is a method where a percentage completion can be measured). This event is only fired when it is possible to know a percentage completion, and when it makes sense to express the operation as a percentage completed. The pctDone argument will have a value from 1 to 100. For operations (Chilkat method calls) that complete very quickly, the number of PercentDone callbacks will vary, but the final callback should have a value of 100. For long running operations, no more than one callback per percentage point will occur (for example: 1, 2, 3, ... 98, 99, 100).

The PercentDone callback counts as an AbortCheck event. For method calls that complete quickly such that PercentDone events fire, it may be that AbortCheck events don't fire because the opportunity to abort is already provided in the PercentDone callback. For time consuming operations, where the amount of time between PercentDone callbacks are long, AbortCheck callbacks may be used to allow for the operation to be aborted in a more responsive manner.

The abort output argument provides a means for aborting the operation. Setting it to true will cause the method to abort and return a failed status (or whatever return value indicates failure).

top
ProgressInfo
void ProgressInfo(const wchar_t *name, const wchar_t *value);

A general name/value event that provides information about what is happening during a method call. To find out what information is available, write code to handle this event and log the name/value pairs. Most are self-explanatory.

top
TaskCompleted
void TaskCompleted(CkTaskW &task);

Called in the background thread when an asynchronous task completes.
