Overview:
When you open a file, fLogViewer prepares the display by building an index. It is possible to view all the lines or to apply a filter.

Filters:

In this case a filter is a name and a regular expression value. This mode can ignore the case or not. Microsoft VBScript version 5.0 or later must be installed.

Like operator:
The LIKE operator provide similar functionality as an regular expression but it is more limited. The like opeator is at least 30% faster than the same regular expression.

VBScript Plug In:
You can write a simple VBScript file which implements the fLogViewer VBScript Plug In Interface. VBScript Sample Based on the VBScript Plug In, it is possible to do more than just dispay a log file. See the VBScript Plug In page.
