* TNTGrid is not capable of displaying a sort arrow in column titles. So, signalize sort direction of columns in grids and listviews by lightgrey (= ascending) and mediumgrey (= descending)
* Remove special color for NULL cells in grids because it can conflict with the new sorting colors. Instead, place a grey (NULL) text in these cells. Less gaudy colors now.
* Also remove grey background in primary key columns for the benefit of sorting colors. PK cells have bold font anyway, should be noticable enough.
- Implement an alternative solution for handling sorted columns without usage of SMDBGrid's sortcolumns. Move relevant structures and functions from data_sorting.pas to childwin.pas and use them in both units.
- Upgrade some code parts to use WideStrings instead of Strings so they don't break with the new grid.
- Use Grid.OnDrawDataCell as an alternative to Grid.OnGetCellParams as the latter one is a feature of SMDBGrid
- Cosmetic: enhance screen real estate in viewdata()
* Bugfix: When methods are called recursively, they should push/pop altered event handlers on a LIFO stack instead of blindly setting and unsetting them.
* Cosmetic: Reclaim screen real estate in ReadDatabasesAndTables().
* Bugfix: Some state changes (tree.Selected) did not correctly take effect when tree.Items.{Begin,End}Update was used, causing an exception later on in GetSelectedTable, GetActiveDatabase etc.
To reproduce the bug, right-click a table, drop it, then right-click another table in same database and choose "refresh".
- Introduce helper "MakeFloat" which does exactly the same as MakeInt except from truncating floats
- Use MakeFloat instead of MakeInt in vstCompareNodes to fix the above mentioned bug
- Show line numbers as they can be quite useful
- Increase starting number when the first line gets deleted from the log, so the line numbers don't lie about the real number of loglines.
* DELIMITER is not a SQL reserved word interpreted in any way by mysqld.
* ComboBoxQueryDelimiterExit was not attached to ComboBoxQueryDelimiter's exit event.
* Fork out IsValidDelimiter to avoid code duplication.
* Simplify delimiter handling:
- Shortcut on whitespace in start of SQL sentences, trims it off by skipping it.
- Remove start_of_command_pos variable in SQL parser, with the above change 'start' is interchangeable.
- Remove comment stating that a delimiter could be part of the SQL command currently being parsed (it can't).
- Disallow DELIMITER inside conditional comment.
- Remove region without matching end-region (?).
- Disallow DELIMITER DELIMITER, it makes for simpler code.
Plus minor optimizations:
* Fast continue at end of one-line comments.
* Test for most-likely-to-fail conditions first in some of the "if"'s.
* Avoid calling (?) Length() for each invocation of the loop.
- File logging can be activated in preferences dialog, by default of course NOT active.
- One file per session is written to [Documents and settings]\[username]\Application data\HeidiSQL\Sessionlogs\
- Filename pattern: "[session name] [zeropadded session nr].log"
- Fetch more descriptive CSIDL_* constants for system folders from ShlObj unit rather than hardcoded hex values
