#170435 - 2006-11-17 10:07 PM INI file size limit?
Glenn Barnas Glenn Barnas KiX Supporter Registered: 2003-01-28 Posts: 4403 Loc: New Jersey	Is there a limit on INI file size? I generated (and can read) an INI file that is 1.1 MB. Have no problem reading it, but when I try to enumerate the sections, I get an "expression too long!" error. The code is: Code: $List = ReadProfileString('.\data.ini', '', '') I'm thinking I may need to split this INI file into smaller parts. Thanks Glenn _________________________ Actually I am a Rocket Scientist! $\:D$

Glenn Barnas Glenn Barnas KiX Supporter Registered: 2003-01-28 Posts: 4403 Loc: New Jersey	I worked around it - I'm able to read/write the entire file, just can't enumerate it. I think Joel hit the nail on this one. The file had 6600 hostnames in it, so certainly larger than 32K Thanks, Glenn

Lonkero Lonkero KiX Master Guru Registered: 2001-06-05 Posts: 22346 Loc: OK	but there shouldn't be no file size limit.

Sealeopard Sealeopard KiX Master Registered: 2001-04-25 Posts: 11165 Loc: Boston, MA, USA	The Windows API is supposed to have a 64k limit. Though I don't think that applies to Windows 2000+ anymore. _________________________ There are two types of vessels, submarines and targets.

Glenn Barnas Glenn Barnas KiX Supporter Registered: 2003-01-28 Posts: 4403 Loc: New Jersey	OK - specifically: I can read it with Open/Readline; I can read/write it with ReadProfileString / WriteProfileString; I CAN NOT do: Code: $String = ReadProfileString('BigFile.ini', '', '') to enumerate all of the headers in the ini file. There are 6600 headers, each about 10-15 characters. If you average them at 13 chars, plus the newline, that's 96K string size. Since I can read/write the file in Kix using different methods, there's no issue with file size - either the enumeration in kix failed, or - more likely - the string size limit has been exceeded.

Sealeopard Sealeopard KiX Master Registered: 2001-04-25 Posts: 11165 Loc: Boston, MA, USA	Don't forget that KiXtart uses the Windows API, thus it might be a problem with the API and not KiXtart itself. _________________________ There are two types of vessels, submarines and targets.

Kdyer Kdyer KiX Supporter Registered: 2001-01-03 Posts: 6241 Loc: Tigard, OR	Glenn, You bring up an interesting point.. That is, from the days of Windows 3.x, the system was able to use the WIN.INI and SYSTEM.INI, but M$ quickly ran into a problem with a 64k ceiling for "reading" INI files. That is why they went to the Registry.. However, the 64k ceiling does not seem to be an issue with KiX as it can "read" files much greater than 64k in size. Anyway, some thoughts to ponder. Kent

Glenn Barnas Glenn Barnas KiX Supporter Registered: 2003-01-28 Posts: 4403 Loc: New Jersey	Yeah - I use INI files all the time to organize large amounts of data, especially where there may be dups of keys. I can read the "count" value for an element, and append it to further elements, incrementing the count every time I write an entry. This way I can identify multiple records. It's kinda like a Hash, but on disk, so I can refer to it later. Never seem to have an issue with file size. Glenn
