top
BeginsWith
bool BeginsWith(string str)

Returns true if the string begins with str. Otherwise returns false. This method is case sensitive.

top
ChopAfter
void ChopAfter(string findStr)

Truncates the string after the 1st occurrence of findStr. If findStr is not present, nothing is truncated.

top
ChopBefore
void ChopBefore(string findStr)

Truncates the string before the 1st occurrence of findStr. If findStr is not present, nothing is truncated.

top
Clear
void Clear()

Clears the string. After calling this method, the string contains 0 characters.

top
Contains
bool Contains(string substr)

VARIANT EmitMultibyte(string charsetEncoding)

Converts the string to a byte array using the character encoding specified by charsetEncoding.

Returns null on failure

top
EndsWith
bool EndsWith(string substr)

Returns true if the string ends with substr (case-sensitive). Otherwise returns false.

top
GetEncoded
string GetEncoded(string binaryEncoding, string charsetEncoding)

Returns the character string in an encoding use the charsetEncoding specified. The binaryEncoding may be "base64", "hex", "url", or "quoted-printable". For example:

(Visual Basic 6.0)

Dim s As New CkString

s.Str = "èèè"
Text1.Text = s.GetEncoded("hex", "iso-8859-1") & vbCrLf
Text1.Text = Text.Text & s.GetEncoded("hex", "utf-8") & vbCrLf
Text1.Text = Text1.Text & s.GetEncoded("hex", "unicode")

'Output:
'E8E8E8
'C3A8C3A8C3A8
'E800E800E800

Returns null on failure

More Information and Examples
top
HtmlEntityEncode

More Information and Examples
top

Length
int Length()

Returns the length, in characters, of the string.

top
LoadFile
bool LoadFile(string path, string charsetEncoding)

Loads an entire text file into the string object. The character encoding of the text file is specified by charsetEncoding. This method allows for text files in any charset to be loaded: utf-8, Unicode, Shift_JIS, iso-8859-1, etc.

More Information and Examples
top
LoadXmlDoc
void LoadXmlDoc(VARIANT xmlDocumentBytes)

Loads an XML document into the CkString. The xmlDocumentBytes contains the raw bytes of the XML document. The reason for providing a separate method for loading an XML document is because the charset encoding is usually specified using a "charset" attribute at the beginning of the XML document. The LoadXmlDoc method reads just enough of the XML document to get the charset, and then it knows how to read and interpret the bytes of the entire XML document, so that the bytes of the characters are properly interpeted and loaded into the CkString object.

top
Matches
bool Matches(string strPattern, bool caseSensitive)

Returns true if the string matches the strPattern, which may contain one or more asterisk wildcard characters. Case-sensitivity is controlled by , where 1 = case sensitive, 0 = case insensitive.

More Information and Examples
top
Mid
string Mid(int index, int numChars)

Same as the VB/VBScript "Mid" function, except that the 1st char is at index 0 (i.e. it is not 1-based). Returns a substring of length numChars starting at index.

Returns null on failure
