StringArray Delphi DLL Reference Documentation

StringArray

Current Version: 9.5.0.73

Class/object for managing and manipulating collections of strings. Contains an ordered collection of strings.

Create/Dispose

var
myObject: HCkStringArray;

begin
myObject := CkStringArray_Create();

// ...

CkStringArray_Dispose(myObject);
end;
function CkStringArray_Create: HCkStringArray; stdcall;

Creates an instance of the HCkStringArray object and returns a handle (i.e. a Pointer). The handle is passed in the 1st argument for the functions listed on this page.

procedure CkStringArray_Dispose(handle: HCkStringArray); stdcall;

Objects created by calling CkStringArray_Create must be freed by calling this method. A memory leak occurs if a handle is not disposed by calling this function.

Properties

Count
function CkStringArray_getCount(objHandle: HCkStringArray): Integer; stdcall;

The number of strings contained within the object's internal array (i.e. ordered collection).

Important: This is an object that contains a collection of strings. Although the class/object name includes the word "Array", it should not be confused with an array in the sense of the primitive array type used in a given programming language.

top
Crlf
function CkStringArray_getCrlf(objHandle: HCkStringArray): wordbool; stdcall;
procedure CkStringArray_putCrlf(objHandle: HCkStringArray; newPropVal: wordbool); stdcall;

If True, strings are always automatically converted to use CRLF line endings. If False, strings are automatically converted to use bare LF line endings.

top
DebugLogFilePath
procedure CkStringArray_getDebugLogFilePath(objHandle: HCkStringArray; outPropVal: HCkString); stdcall;
procedure CkStringArray_putDebugLogFilePath(objHandle: HCkStringArray; newPropVal: PWideChar); stdcall;
function CkStringArray__debugLogFilePath(objHandle: HCkStringArray): PWideChar; stdcall;

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
procedure CkStringArray_getLastErrorHtml(objHandle: HCkStringArray; outPropVal: HCkString); stdcall;
function CkStringArray__lastErrorHtml(objHandle: HCkStringArray): PWideChar; stdcall;

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
procedure CkStringArray_getLastErrorText(objHandle: HCkStringArray; outPropVal: HCkString); stdcall;
function CkStringArray__lastErrorText(objHandle: HCkStringArray): PWideChar; stdcall;

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
procedure CkStringArray_getLastErrorXml(objHandle: HCkStringArray; outPropVal: HCkString); stdcall;
function CkStringArray__lastErrorXml(objHandle: HCkStringArray): PWideChar; stdcall;

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
function CkStringArray_getLastMethodSuccess(objHandle: HCkStringArray): wordbool; stdcall;
procedure CkStringArray_putLastMethodSuccess(objHandle: HCkStringArray; newPropVal: wordbool); stdcall;
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
Length
function CkStringArray_getLength(objHandle: HCkStringArray): Integer; stdcall;

The number of strings contained within the internal collection. (Identical to the Count property.)

top
Trim
function CkStringArray_getTrim(objHandle: HCkStringArray): wordbool; stdcall;
procedure CkStringArray_putTrim(objHandle: HCkStringArray; newPropVal: wordbool); stdcall;

If True, whitespace, including carriage-returns and linefeeds, are automatically removed from the beginning and end of a string when added to the collection.

top
Unique
function CkStringArray_getUnique(objHandle: HCkStringArray): wordbool; stdcall;
procedure CkStringArray_putUnique(objHandle: HCkStringArray; newPropVal: wordbool); stdcall;

If True, then duplicates are not allowed. When an attempt is made to insert a string that already exists, the duplicate insertion is silently suppressed and no error is returned. The default value is False.

top
VerboseLogging
function CkStringArray_getVerboseLogging(objHandle: HCkStringArray): wordbool; stdcall;
procedure CkStringArray_putVerboseLogging(objHandle: HCkStringArray; newPropVal: wordbool); stdcall;

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
procedure CkStringArray_getVersion(objHandle: HCkStringArray; outPropVal: HCkString); stdcall;
function CkStringArray__version(objHandle: HCkStringArray): PWideChar; stdcall;

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