Url Delphi DLL Reference Documentation

Url

Current Version: 9.5.0.73

Provides an object representation of a URL and easy access to the parts of the URL.

Create/Dispose

var
myObject: HCkUrl;

begin
myObject := CkUrl_Create();

// ...

CkUrl_Dispose(myObject);
end;
function CkUrl_Create: HCkUrl; stdcall;

Creates an instance of the HCkUrl 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 CkUrl_Dispose(handle: HCkUrl); stdcall;

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

Properties

Frag
procedure CkUrl_getFrag(objHandle: HCkUrl; outPropVal: HCkString); stdcall;
function CkUrl__frag(objHandle: HCkUrl): PWideChar; stdcall;
Introduced in version 9.5.0.49

Contains any text following a fragment marker (#) in the URL, excluding the fragment marker. Given the URI http://www.contoso.com/index.htm#main, the fragment is "main".

top
Host
procedure CkUrl_getHost(objHandle: HCkUrl; outPropVal: HCkString); stdcall;
function CkUrl__host(objHandle: HCkUrl): PWideChar; stdcall;
Introduced in version 9.5.0.49

The DNS host name or IP address part of the URL. For example, if the URL is "http://www.contoso.com:8080/", the Host is "www.contoso.com". If the URL is "https://192.168.1.124/test.html", the Host is "192.168.1.124".

HostType
procedure CkUrl_getHostType(objHandle: HCkUrl; outPropVal: HCkString); stdcall;
function CkUrl__hostType(objHandle: HCkUrl): PWideChar; stdcall;
Introduced in version 9.5.0.49

The type of the host name specified in the URL. Possible values are:

  • "dns": The host name is a domain name system (DNS) style host name.
  • "ipv4": The host name is an Internet Protocol (IP) version 4 host address.
  • "ipv6": The host name is an Internet Protocol (IP) version 6 host address.

LastMethodSuccess
function CkUrl_getLastMethodSuccess(objHandle: HCkUrl): wordbool; stdcall;
procedure CkUrl_putLastMethodSuccess(objHandle: HCkUrl; newPropVal: wordbool); stdcall;

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.

Login
procedure CkUrl_getLogin(objHandle: HCkUrl; outPropVal: HCkString); stdcall;
function CkUrl__login(objHandle: HCkUrl): PWideChar; stdcall;
Introduced in version 9.5.0.49

If the URL contains a login and password, this is the login part. For example, if the URL is "http://user:password@www.contoso.com/index.htm ", then the login is "user".

If the URL contains a login and password, this is the password part. For example, if the URL is "http://user:password@www.contoso.com/index.htm ", then the password is "password".

procedure CkUrl_getPath(objHandle: HCkUrl; outPropVal: HCkString); stdcall;
function CkUrl__path(objHandle: HCkUrl): PWideChar; stdcall;
