These functions include doc. As you can read here: Acrobat provides us with two modes of operation for these functions--with a path and without a path. If no path parameter is provided to the function, Acrobat displays a file-browser dialog.
The file browser dialog gives users control over how data is saved to their systems. If a path is provided to the function, then no dialog is displayed and the operation is handled silently, i.
This is a security problem, so to use one of these functions in silent mode, the function must be executed from a privileged context. This means the code must reside in a trusted location. When any of these functions are used with a path parameter and executed in a non-privileged context, Acrobat will throw an exception.
Examples of these restricted locations are the system folder and the root folder of any hard drive.
Other folders that might be restricted are dependent on the operating system and the sensibilities of the Acrobat developers.
A path cannot point to a system critical folder, for example a root, windows or system directory. A path is also subject to other unspecified tests. For many methods, the file name must have an extension appropriate to the type of data that is to be saved.
Some methods may have a no-overwrite restriction. These additional restrictions are noted in the documentation. Generally, when a path is judged to be not safe, a NotAllowedError exception is thrown see Error object and the method fails.
The "cName" parameter is a required input and specifies the specific file attachment that will be exported. Notice there is no path parameter. There is in fact a "cPath" input to this function, but it is no longer valid. If you try to use a path in this function, it will fail and throw an exception.Do not attempt to include both.
To help make sense of the API, the following diagram arranges the file I/O methods by complexity. function WriteFile().
var fh = fopen("c:\\caninariojana.com", 3); // Open the file for writing if(fh!=-1) // If the file has been successfully opened var str = "Some text. As a continuation from my last post where I have used grep & tail -f to find occurences of "rare" events.
