Returns the component's expiration date obtained from the registration key in use. If the returned value is 9/9/9999, it means the registration key is permanent.

Returns the current component version in the format "X.X.X.X Build XXXX", for example "1.0.0.0 Build 3567".

Creates an empty PDF document, returns an instance of the PdfDocument object representing this document.

ID is a binary number, specified as a hex string, to be used as this document's identifier. If this argument is omitted, AspPDF will generate a random 128-bit document identifier. Use this argument only if you need your document to have a specific identifier for accountability or other purposes. The current document identifier can be retrieved via PdfDocument's ID property.

This is an auxiliary method which returns a formatted string for a Date.

Usage:

str = Pdf.FormatDate( Now, "%d %b %Y") ' produces "17 Nov 2003"

An auxiliary method that returns a formatted string for a Number. Param is a PdfParam object or parameter string specifying various formatting parameters (all optional), including:

• Precision - the number of decimals after the decimal point. 6 by default.
• Delimiter - if set to True, thousands delimiters are inserted. False by default.
• NoMinus - if set to True, uses parentheses for negative numbers instead of the minus sign. False by default.
• European - if set to True, uses "," for the decimal point and "." for thousands separators. False by default.

Usage:

' Produces 1,234.57
str = Pdf.FormatNumber(1234.56789, "Precision=2, Delimiter=true")

' Produces 1.234,57
str = Pdf.FormatNumber(1234.56789, "Precision=2, Delimiter=true; European=true")

An auxiliary method which loads a text string from a file specified by Path. A file can be in ANSI or Unicode (little endian or big endian) formats.

All text-handling method such as PdfCanvas.DrawText expect a text string to be passed as an argument. If the text to be drawn resides in a file, the LoadTextFromFile method can be used to load the file into a text string which can them be passed to a text-drawing method.

Impersonates the specified user account. If Domain is empty, the local computer will be used to validate the password. Use this function if your current security context does not allow you to perform a certain operation such as sending an image to the network printer.

Flags may be set to one of the following values: LOGON_INTERACTIVE (2, default), LOGON_NETWORK (3), LOGON_BATCH (4), and LOGON_SERVICE (5). Using this optional parameter is not recommended.

This method was introduced in Version 2.1.

Calls the Win32 API ::RevertToSelf to run the component under the system account's security context. This helps overcome certain permission problems when working with files and the system registry (such as obtaining font information from the registry when calling Fonts.Item) without having to tweak permissions. This method is only effective under ASP but not ASP.NET.

Sends an arbitrary file specified via Path from the server's hard drive to the client browser. This method can only be used under ASP and ASP.NET, but not VB or any other non-IIS environment. When used under ASP.NET, the classic ASP compatibility mode must be enabled, as follows:

<%@ Page aspCompat="True" other attributes %>

A script calling this method must not have any HTML tags in it (not even comments) as they would corrupt the HTTP stream.

ContentType optionally specifies the Content-Type header for the HTTP stream. This argument is "application/pdf" by default.

DispHeader optionally specifies the Content-Disposition header for the HTTP stream. By default, the header is set to "attachment; filename=filename.ext" based on the name of the file being sent. You may choose to pass a value for this argument if you want to specify a filename other than the actual document name.

Usage:

Pdf.SendBinary "c:\path\a.pdf", , "attachment; filename=b.pdf"
