Mht Delphi DLL Reference Documentation

Mht

Chilkat MHT can generate email objects from HTML files and URLs, and convert HTML to MHT or EML files.

Create/Dispose

function CkMht_Create: HCkMht; stdcall;

Creates an instance of the HCkMht 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 CkMht_Dispose(handle: HCkMht); stdcall;

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

Properties

function CkMht_getAbortCurrent(objHandle: HCkMht): wordbool; stdcall;
procedure CkMht_putAbortCurrent(objHandle: HCkMht; newPropVal: wordbool); stdcall;

Introduced in version 9.5.0.58

When set to True, causes the currently running method to abort. Methods that always finish quickly (i.e.have no length file operations or network communications) are not affected. If no method is running, then this property is automatically reset to False when the next method is called. When the abort occurs, this property is reset to False. Both synchronous and asynchronous method calls can be aborted. (A synchronous method call could be aborted by setting this property from a separate thread.)

procedure CkMht_getBaseUrl(objHandle: HCkMht; outPropVal: HCkString); stdcall;
procedure CkMht_putBaseUrl(objHandle: HCkMht; newPropVal: PWideChar); stdcall;

function CkMht__baseUrl(objHandle: HCkMht): PWideChar; stdcall;

When processing an HTML file or string (not a website URL), this defines the base URL to be used when converting relative HREFs to absolute HREFs.

function CkMht_getConnectTimeout(objHandle: HCkMht): Integer; stdcall;
procedure CkMht_putConnectTimeout(objHandle: HCkMht; newPropVal: Integer); stdcall;

The amount of time in seconds to wait before timing out when connecting to an HTTP server. The default value is 10 seconds.

procedure CkMht_getDebugHtmlAfter(objHandle: HCkMht; outPropVal: HCkString); stdcall;
procedure CkMht_putDebugHtmlAfter(objHandle: HCkMht; newPropVal: PWideChar); stdcall;

function CkMht__debugHtmlAfter(objHandle: HCkMht): PWideChar; stdcall;

A filename to save the result HTML when converting a URL, file, or HTML string. If problems are experienced, the before/after HTML can be analyzed to help determine the cause.

procedure CkMht_getDebugHtmlBefore(objHandle: HCkMht; outPropVal: HCkString); stdcall;
procedure CkMht_putDebugHtmlBefore(objHandle: HCkMht; newPropVal: PWideChar); stdcall;

function CkMht__debugHtmlBefore(objHandle: HCkMht): PWideChar; stdcall;

A filename to save the input HTML when converting a URL, file, or HTML string. If problems are experienced, the before/after HTML can be analyzed to help determine the cause.

procedure CkMht_getDebugLogFilePath(objHandle: HCkMht; outPropVal: HCkString); stdcall;
procedure CkMht_putDebugLogFilePath(objHandle: HCkMht; newPropVal: PWideChar); stdcall;

function CkMht__debugLogFilePath(objHandle: HCkMht): 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.

function CkMht_getDebugTagCleaning(objHandle: HCkMht): wordbool; stdcall;
procedure CkMht_putDebugTagCleaning(objHandle: HCkMht; newPropVal: wordbool); stdcall;

When True causes the Mht class to be much more verbose in its logging. The default is False.

function CkMht_getEmbedImages(objHandle: HCkMht): wordbool; stdcall;
procedure CkMht_putEmbedImages(objHandle: HCkMht; newPropVal: wordbool); stdcall;

Controls whether images are embedded in the MHT/EML, or whether the IMG SRC attributes are left as external URL references. If false, the IMG SRC tags are converted to absolute URLs (if necessary) and the images are not embedded within the MHT/EML.

function CkMht_getEmbedLocalOnly(objHandle: HCkMht): wordbool; stdcall;
procedure CkMht_putEmbedLocalOnly(objHandle: HCkMht; newPropVal: wordbool); stdcall;

If True, only images found on the local filesystem (i.e. links to files) will be embedded within the MHT.

function CkMht_getFetchFromCache(objHandle: HCkMht): wordbool; stdcall;
procedure CkMht_putFetchFromCache(objHandle: HCkMht; newPropVal: wordbool); stdcall;

If True, page parts such as images, style sheets, etc. will be fetched from the disk cache if possible. The disk cache root may be defined by calling AddCacheRoot. The default value is False.

function CkMht_getIgnoreMustRevalidate(objHandle: HCkMht): wordbool; stdcall;
procedure CkMht_putIgnoreMustRevalidate(objHandle: HCkMht; newPropVal: wordbool); stdcall;

Some HTTP responses contain a "Cache-Control: must-revalidate" header. If this is present, the server is requesting that the client always issue a revalidate HTTP request instead of serving the page directly from cache. If IgnoreMustRevalidate is set to True, then Chilkat MHT will serve the page directly from cache without revalidating until the page is no longer fresh. (assuming that FetchFromCache is set to True)

The default value of this property is False.

function CkMht_getIgnoreNoCache(objHandle: HCkMht): wordbool; stdcall;
procedure CkMht_putIgnoreNoCache(objHandle: HCkMht; newPropVal: wordbool); stdcall;

Some HTTP responses contain headers of various types that indicate that the page should not be cached. Chilkat MHT will adhere to this unless this property is set to True.

The default value of this property is False.

procedure CkMht_getLastErrorHtml(objHandle: HCkMht; outPropVal: HCkString); stdcall;

function CkMht__lastErrorHtml(objHandle: HCkMht): 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.

procedure CkMht_getLastErrorText(objHandle: HCkMht; outPropVal: HCkString); stdcall;

function CkMht__lastErrorText(objHandle: HCkMht): 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.

procedure CkMht_getLastErrorXml(objHandle: HCkMht; outPropVal: HCkString); stdcall;

function CkMht__lastErrorXml(objHandle: HCkMht): 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.

function CkMht_getLastMethodSuccess(objHandle: HCkMht): wordbool; stdcall;
procedure CkMht_putLastMethodSuccess(objHandle: HCkMht; 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.

function CkMht_getNoScripts(objHandle: HCkMht): wordbool; stdcall;
procedure CkMht_putNoScripts(objHandle: HCkMht; newPropVal: wordbool); stdcall;

Only applies when creating MHT files. Scripts are always removed when creating EML or emails from HTML. If set to True, then all scripts are removed, if set to False (the default) then scripts are not removed.

function CkMht_getNtlmAuth(objHandle: HCkMht): wordbool; stdcall;
procedure CkMht_putNtlmAuth(objHandle: HCkMht; newPropVal: wordbool); stdcall;

Setting this property to True causes the MHT component to use NTLM authentication (also known as IWA -- or Integrated Windows Authentication) when authentication with an HTTP server.

The default value of this property is False.

function CkMht_getNumCacheLevels(objHandle: HCkMht): Integer; stdcall;
procedure CkMht_putNumCacheLevels(objHandle: HCkMht; newPropVal: Integer); stdcall;

The number of directory levels to be used under each cache root. The default is 0, meaning that each cached item is stored in a cache root directory. A value of 1 causes each cached page to be stored in one of 255 subdirectories named "0","1", "2", ..."255" under a cache root. A value of 2 causes two levels of subdirectories ("0..255/0..255") under each cache root. The MHT control automatically creates subdirectories as needed. The reason for mutliple levels is to alleviate problems that may arise when huge numbers of files are stored in a single directory. For example, Windows Explorer does not behave well when trying to display the contents of directories with thousands of files.

function CkMht_getNumCacheRoots(objHandle: HCkMht): Integer; stdcall;

The number of cache roots to be used for the disk cache. This allows the disk cache spread out over multiple disk drives. Each cache root is a string indicating the drive letter and directory path. For example, "E:\Cache". To create a cache with four roots, call AddCacheRoot once for each directory root.

function CkMht_getPreferIpv6(objHandle: HCkMht): wordbool; stdcall;
procedure CkMht_putPreferIpv6(objHandle: HCkMht; newPropVal: wordbool); stdcall;

If True, then use IPv6 over IPv4 when both are supported for a particular domain. The default value of this property is False, which will choose IPv4 over IPv6.

function CkMht_getPreferMHTScripts(objHandle: HCkMht): wordbool; stdcall;
procedure CkMht_putPreferMHTScripts(objHandle: HCkMht; newPropVal: wordbool); stdcall;

This property provides a means for the noscript option to be selected when possible. If PreferMHTScripts = False, then scripts with noscript alternatives are removed and the noscript content is kept. If True (the default), then scripts are preserved and the noscript options are discarded.

procedure CkMht_getProxy(objHandle: HCkMht; outPropVal: HCkString); stdcall;
procedure CkMht_putProxy(objHandle: HCkMht; newPropVal: PWideChar); stdcall;

function CkMht__proxy(objHandle: HCkMht): PWideChar; stdcall;

(Optional) A proxy host:port if a proxy is necessary to access the Internet. The proxy string should be formatted as "hostname:port", such as "www.chilkatsoft.com:100".

procedure CkMht_getProxyLogin(objHandle: HCkMht; outPropVal: HCkString); stdcall;
procedure CkMht_putProxyLogin(objHandle: HCkMht; newPropVal: PWideChar); stdcall;

function CkMht__proxyLogin(objHandle: HCkMht): PWideChar; stdcall;

procedure CkMht_getProxyPassword(objHandle: HCkMht; outPropVal: HCkString); stdcall;
procedure CkMht_putProxyPassword(objHandle: HCkMht; newPropVal: PWideChar); stdcall;

function CkMht__proxyPassword(objHandle: HCkMht): PWideChar; stdcall;

If an HTTP proxy is used and it requires authentication, this property specifies the HTTP proxy password.

function CkMht_getReadTimeout(objHandle: HCkMht): Integer; stdcall;
procedure CkMht_putReadTimeout(objHandle: HCkMht; newPropVal: Integer); stdcall;

The amount of time in seconds to wait before timing out when reading from an HTTP server. The ReadTimeout is the amount of time that needs to elapse while no additional data is forthcoming. During a long data transfer, if the data stream halts for more than this amount, it will timeout. Otherwise, there is no limit on the length of time for the entire data transfer.

The default value is 20 seconds.

function CkMht_getRequireSslCertVerify(objHandle: HCkMht): wordbool; stdcall;
procedure CkMht_putRequireSslCertVerify(objHandle: HCkMht; newPropVal: wordbool); stdcall;

If True, then the HTTP client will verify the server's SSL certificate. The certificate is expired, or if the cert's signature is invalid, the connection is not allowed. The default value of this property is False.

procedure CkMht_getSocksHostname(objHandle: HCkMht; outPropVal: HCkString); stdcall;
procedure CkMht_putSocksHostname(objHandle: HCkMht; newPropVal: PWideChar); stdcall;

function CkMht__socksHostname(objHandle: HCkMht): PWideChar; stdcall;

The SOCKS4/SOCKS5 hostname or IPv4 address (in dotted decimal notation). This property is only used if the SocksVersion property is set to 4 or 5).

procedure CkMht_getSocksPassword(objHandle: HCkMht; outPropVal: HCkString); stdcall;
procedure CkMht_putSocksPassword(objHandle: HCkMht; newPropVal: PWideChar); stdcall;

function CkMht__socksPassword(objHandle: HCkMht): PWideChar; stdcall;

The SOCKS5 password (if required). The SOCKS4 protocol does not include the use of a password, so this does not apply to SOCKS4.

function CkMht_getSocksPort(objHandle: HCkMht): Integer; stdcall;
procedure CkMht_putSocksPort(objHandle: HCkMht; newPropVal: Integer); stdcall;

The SOCKS4/SOCKS5 proxy port. The default value is 1080. This property only applies if a SOCKS proxy is used (if the SocksVersion property is set to 4 or 5).

procedure CkMht_getSocksUsername(objHandle: HCkMht; outPropVal: HCkString); stdcall;
procedure CkMht_putSocksUsername(objHandle: HCkMht; newPropVal: PWideChar); stdcall;

function CkMht__socksUsername(objHandle: HCkMht): PWideChar; stdcall;

The SOCKS4/SOCKS5 proxy username. This property is only used if the SocksVersion property is set to 4 or 5).

function CkMht_getSocksVersion(objHandle: HCkMht): Integer; stdcall;
procedure CkMht_putSocksVersion(objHandle: HCkMht; newPropVal: Integer); stdcall;

SocksVersion May be set to one of the following integer values:

0 - No SOCKS proxy is used. This is the default.
4 - Connect via a SOCKS4 proxy.
5 - Connect via a SOCKS5 proxy.

function CkMht_getUnpackDirect(objHandle: HCkMht): wordbool; stdcall;
procedure CkMht_putUnpackDirect(objHandle: HCkMht; newPropVal: wordbool); stdcall;

Introduced in version 9.5.0.47

If True, then the UnpackMHT and UnpackMHTString methods will unpack the MHT directly with no transformations. Normally, the related parts are unpacked to a "parts" sub-directory, and the unpacked HTML is edited to update references to point to the unpacked image and script files. When unpacking direct, the HTML is not edited, and the related parts are unpacked to sub-directories rooted in the directory where HTML file is created (i.e. the unpack directory). When unpacking direct, the "partsSubDir" argument of the UnpackMHT* methods is unused.

Note: It is only possible to directly unpack MHT files where the Content-Location headers DO NOT contain URLs. The MHT must be such that the Content-Location headers of the related items contain relative paths.

Note: The default value of this property is False.

function CkMht_getUnpackUseRelPaths(objHandle: HCkMht): wordbool; stdcall;
procedure CkMht_putUnpackUseRelPaths(objHandle: HCkMht; newPropVal: wordbool); stdcall;

Controls whether absolute or relative paths are used when referencing images in the unpacked HTML. The default value is True indicating that relative paths will be used. To use absolute paths, set this property value equal to False.

function CkMht_getUpdateCache(objHandle: HCkMht): wordbool; stdcall;
procedure CkMht_putUpdateCache(objHandle: HCkMht; newPropVal: wordbool); stdcall;

Controls whether the cache is automatically updated with the responses from HTTP GET requests. If True, the disk cache is updated, if False (the default), the cache is not updated.

function CkMht_getUseCids(objHandle: HCkMht): wordbool; stdcall;
procedure CkMht_putUseCids(objHandle: HCkMht; newPropVal: wordbool); stdcall;

Controls whether CID URLs are used for embedded references when generating MHT or EML documents. If UseCids is False, then URLs are left unchanged and the embedded items will contain "content-location" headers that match the URLs in the HTML. If True, CIDs are generated and the URLs within the HTML are replaced with "CID:" links.

The default value of this property is True.

function CkMht_getUseFilename(objHandle: HCkMht): wordbool; stdcall;
procedure CkMht_putUseFilename(objHandle: HCkMht; newPropVal: wordbool); stdcall;

If True, a "filename" attribute is added to each Content-Disposition MIME header field for each embedded item (image, style sheet, etc.). If False, then no filename attribute is added.

The default value of this property is True.

function CkMht_getUseInline(objHandle: HCkMht): wordbool; stdcall;
procedure CkMht_putUseInline(objHandle: HCkMht; newPropVal: wordbool); stdcall;

If True, an "inline" attribute is added to each Content-Disposition MIME header field for each embedded item (image, style sheet, etc.). If False, then no inline attribute is added.

The default value of this property is True.

function CkMht_getVerboseLogging(objHandle: HCkMht): wordbool; stdcall;
procedure CkMht_putVerboseLogging(objHandle: HCkMht; 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.

procedure CkMht_getVersion(objHandle: HCkMht; outPropVal: HCkString); stdcall;

function CkMht__version(objHandle: HCkMht): PWideChar; stdcall;

Version of the component/library, such as "9.4.1.42"

Optional) Specifies the password if a a Web page is accessed that requires a login and password

Methods

procedure CkMht_AddCacheRoot(objHandle: HCkMht;
    dir: PWideChar); stdcall;

If disk caching is used, this must be called once for each cache root. For example, if the cache is spread across D:\cacheRoot, E:\cacheRoot, and F:\cacheRoot, an application would setup the cache object by calling AddRoot three times -- once with "D:\cacheRoot", once with "E:\cacheRoot", and once with "F:\cacheRoot".

Download Web Page to MHT with w/ Disk Cache

procedure CkMht_AddCustomHeader(objHandle: HCkMht;
    name: PWideChar;
    value: PWideChar); stdcall;

Adds a custom HTTP header to all HTTP requests sent by the MHT component. To add multiple header fields, call this method once for each custom header.

procedure CkMht_AddExternalStyleSheet(objHandle: HCkMht;
    url: PWideChar); stdcall;

(This method rarely needs to be called.) Includes an additional style sheet that would not normally be included with the HTML. This method is provided for cases when style sheet names are constructed and dynamically included in Javascript such that MHT .NET cannot know beforehand what stylesheet to embed. MHT .NET by default downloads and embeds all stylesheets externally referenced by the HTML

procedure CkMht_ClearCustomHeaders(objHandle: HCkMht); stdcall;

Removes all custom headers that may have accumulated from previous calls to AddCustomHeader.

procedure CkMht_ExcludeImagesMatching(objHandle: HCkMht;
    pattern: PWideChar); stdcall;

(This method rarely needs to be called.) Tells Chilkat MHT .NET to not embed any images whose URL matches a pattern. Sometimes images can be referenced within style sheets and not actually used when rendering the page. In cases like those, the image will appear as an attachment in the HTML email. This feature allows you to explicitly remove those images from the email so no attachments appear.

function CkMht_GetAndSaveEML(objHandle: HCkMht;
    url_or_htmlFilepath: PWideChar;
