TranslateSetPostProcessHook Function

Overview

The TranslateSetPostProcessHook function sets a hook for post processing on an import function.

Syntax/Parameters

Syntax

int = TranslateSetPostProcessHook ( string script, string function );

Parameters

script

An optional string that specifies the script that will service the post translate processing. If empty, the script name from the script executing the function is used.

function

A string specifying the name of the entry function for post processing. If the script and function strings are empty, the hook is reset.

Return Value

An int as ERROR_NONE (0) or a formatted error code on failure.

Remarks

A post process hook can be used to perform refining or other functions after data has been translated and before it has been opened, imported or completed. The post process does not presently run on Paste Special operations.

The script is run “cold” each time and as such, any variables set from execution to execution are discarded. Use the session data functions to store intermediate data. See section Section 4.15 Session Data for additional information.

This function allows the import and translate function to be extended by post processing. An example of adding a hook:

TranslateSetPostProcessHook("", "rename_images");

Note that the script name parameter is an empty, thus the hook script is the source for the specified connection. The hook is normally defined during application startup. See Section 17.2 Application Startup for more information.

The script parameter is tested for existence on setting the hook. The function parameter is not tested. Neither the script’s syntax or functionality is tested while setting the hook. On hook execution, a script error will be added to the log and the script hook will be removed.

The hook entry point in the script must match the following template:

int post_process_hook (string xl_type, string xl_src, string xl_dst, string xl_dst_base,
dword xl_flags, string xl_options);

Where

xl_type

A string contain the name of the conversion performed.

xl_src

A string containing a fully qualified source file. It can be a URI. The source should be used for reference purposes as it specifies the data that has already been converted.

xl_dst

A string containing a fully qualified destination file. The file can be in the application (user’s) temporary area. This is the file that can be opened and manipulated during the post process.

xl_dst_base

A string containing a the base path for the destination. If image or other companion files must be created, they should be placed in this folder.

xl_flags

A dword specifying various control bits.

xl_options

A string in the form of parameter: value pairs that may be passed with data from the API or other source and can be used by the script to set various options. These are override values from the default settings.

The xl_flags parameter tells the hook about the context and requested operations. These are bitwise items specified as follows:

Definition		Bitwise	Comment/Description
Shares with Options Settings
	XL_GLOBAL_FLAGS_MASK	0xFFFF0000	Global Import/Translate Options
	XL_MODULE_FLAGS_MASK	0x0000FFFF	Reserved Import/Translate Options
	XL_SUB_TYPE_MASK	0x0000000F	Sub Type of Conversion for Module
General Flags
Control
	XL_QUIET	0x00010000	Do Not Display Messages
	XL_PSG_FORMAT	0x00020000	Output in PSG Format (if possible)
	XL_NO_NEW_LINES	0x00040000	Output With 0x0D (not 0x0D/0x0A)
	XL_WANT_LOG	0x00080000	Output Errors to Translate Log
Context
	XL_CONVERT_AS_INSERT	0x00100000	Treat as Inserting
	XL_MULTI_IMPORT	0x00200000	Importing Multiple Sheets
	XL_SOURCED_FROM_CLIPBOARD	0x00400000	Sourced from Clipboard
Multiple Files
	XL_GROUP_IMPORT_MODE_MASK	0x03000000	Multiple File Mode (if supported)
	XL_GROUP_IMPORT_SINGLE	0x00000000	Import Single File
	XL_GROUP_IMPORT_MULTIPLE	0x01000000	Automatically Import Multiple
	XL_GROUP_IMPORT_QUERY	0x02000000	Query if Multiple

The default log for the script is imported back into the caller to the hook and then included into the Information View window.

The XL_SOURCED_FROM_CLIPBOARD flag will indicate whether the source data was retrieved from the clipboard. If the XL_QUIET, the hook should not display message boxes or dialog boxes.

A formatted error code should be returned upon completion or error. The script should perform its own cleanup.
