Create/Dispose
HCkDtObjW instance = CkDtObjW_Create(); // ... CkDtObjW_Dispose(instance);
Creates an instance of the HCkDtObjW object and returns a handle ("void *" pointer). The handle is passed in the 1st argument for the functions listed on this page.
Objects created by calling CkDtObjW_Create must be freed by calling this method. A memory leak occurs if a handle is not disposed by calling this function. Also, any handle returned by a Chilkat "C" function must also be freed by the application by calling the appropriate Dispose method, such as CkDtObjW_Dispose.
Properties
Day
void CkDtObjW_putDay(HCkDtObjW cHandle, int newVal);
The day of the month. The valid values for this member are 1 through 31.
topDebugLogFilePath
void CkDtObjW_putDebugLogFilePath(HCkDtObjW cHandle, const wchar_t *newVal);
const wchar_t *CkDtObjW_debugLogFilePath(HCkDtObjW cHandle);
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.
Hour
void CkDtObjW_putHour(HCkDtObjW cHandle, int newVal);
The hour. The valid values for this member are 0 through 23.
topLastErrorHtml
const wchar_t *CkDtObjW_lastErrorHtml(HCkDtObjW cHandle);
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.
topLastErrorText
const wchar_t *CkDtObjW_lastErrorText(HCkDtObjW cHandle);
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
const wchar_t *CkDtObjW_lastErrorXml(HCkDtObjW cHandle);
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.
topLastMethodSuccess
void CkDtObjW_putLastMethodSuccess(HCkDtObjW cHandle, BOOL newVal);
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.
topMinute
void CkDtObjW_putMinute(HCkDtObjW cHandle, int newVal);
The minute. The valid values for this member are 0 through 59.
topMonth
void CkDtObjW_putMonth(HCkDtObjW cHandle, int newVal);
The month. The valid values for this member are 1 through 12 where 1 = January and 12 = December.
topSecond
void CkDtObjW_putSecond(HCkDtObjW cHandle, int newVal);
The second. The valid values for this member are 0 through 59.
topStructTmMonth
void CkDtObjW_putStructTmMonth(HCkDtObjW cHandle, int newVal);
The month. The valid values for this member are 0 through 11 where 0 = January and 11 = December.
topStructTmYear
void CkDtObjW_putStructTmYear(HCkDtObjW cHandle, int newVal);
The year represented as the number of years since 1900.
topUtc
void CkDtObjW_putUtc(HCkDtObjW cHandle, BOOL newVal);
TRUE if this is a UTC time, otherwise FALSE if this is a local time.
topVerboseLogging
void CkDtObjW_putVerboseLogging(HCkDtObjW cHandle, 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.
topVersion
const wchar_t *CkDtObjW_version(HCkDtObjW cHandle);
Year
void CkDtObjW_putYear(HCkDtObjW cHandle, int newVal);
The year, such as 2012.
topMethods
DeSerialize
Loads the date/time with a string having the format as produced by the Serialize method, which is a string of SPACE separated integers containing (in this order) year, month, day, hour, minutes, seconds, and a UTC flag having the value of 1/0.
topSerialize
const wchar_t *CkDtObjW_serialize(HCkDtObjW cHandle);
Serializes the date/time to a us-ascii string that can be imported at a later time via the DeSerialize method. The format of the string returned by this method is not intended to match any published standard. It is formatted to a string with SPACE separated integers containing (in this order) year, month, day, hour, minutes, seconds, and a UTC flag having the value of 1/0.
Returns TRUE for success, FALSE for failure.
