Ini file storage capacity

Recommended Posts

WiseGuy

Hi all,

To store data for the functioning of my application, I wish to use the ini-file format but, having experience in other programming languages, I know there's a cap on how much an ini-file can store. So my question is: does AutoIt use the normal Windows ini-format with it's 32kB limit or does it have it's own custom implementation allowing for larger filesizes?

If it does use the default 32kB limit, what would you guys do when you want to store a truckload of information? I'm thinking in that case of using a regular textdoc but not quite sure how to implement that in AutoIt so could you in that case point me in the right direction?

EDIT: In most cases the file won't be extremely large, just containing a set of clicks and settings but since the way I want to implement it (where users can add clicks at will) it can get very large and I want to take that into acount.

Thanks in advance,

WiseGuy

Maybe you search this? :huh:

IniWrite ( "filename", "section", "key", "value" )

Don't have such limitations like 32kB.

Jayson,

Did you create that yourself? If not then please link to the UDF instead of duplicating code. Thanks.

The only 32K limit that applies to INI files is reading a section, the ini file itself can be much larger.

Although, if you have a 32Kb section, it might be a better idea to split it.


If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

Another not-as-complicated-as-it-sounds way is to use a database. The easiest to setup and use is SQLite, which enjoys standard UDF support.


This wonderful site allows debugging and testing regular expressions (many flavors available). An absolute must have in your bookmarks.

SmOke_N wrote a UDF replacement for the inifile functions which does not have the 32k limit.

You can find it in


Serial port communications UDF Includes functions for binary transmission and reception.printing UDF Useful for graphs, forms, labels, reports etc.Add User Call Tips to SciTE for functions in UDFs not included with AutoIt and for your own scripts.Functions with parameters in OnEvent mode and for Hot Keys One function replaces GuiSetOnEvent, GuiCtrlSetOnEvent and HotKeySet.UDF IsConnected2 for notification of status of connected state of many urls or IPs, without slowing the script.
