f148664018 * Zeos: Make SetFieldData() public to provide a way to poke NULL into a field. 
* Heidi: Use above to set field to NULL when requested by user.

c40b8d680b Bugfix: Setting a field to an empty string causes a WriteBuffer(nil, 0) which in turn apparently causes Memory to be nil. Therefore, interpret this as empty string rather than NULL. Fixes issue #316. 2008-06-25 13:05:16 +00:00

ca940f56a2 Bugfix: Missing use of Wide version method. Might fix issue #540. 2008-06-25 13:02:05 +00:00

d0fd412c03 * Bugfix: Correct cast when retrieving wide data from buffer is PWideChar. 
* Bugfix: FBlobSize is in bytes, SetString expects a character count.

7219960e50 Get rid of some implicit WideString -> string conversions (annoying!). Still missing: FormInsertStatement(), FormDeleteStatement() and FormUpdateStatement(). 2008-06-24 17:50:06 +00:00

1bd1bb8a6e Remove preference option to select whether auto limiting should be applied or not, for the benefit of consistency and usability. See bug #282 which complains about the limit not being remembered. This is still the case for large tables now, but GetCalculatedLimit is more a safety check to avoid huge net loads than it wants to annoy the user. A even better compromise could be not to touch the limit number in the GUI if its value is lower than GetCalculatedLimit. 2008-06-23 20:15:37 +00:00

dced2df45e Make query execution unicode safe, mainly for a bunch of procedures and functions in Heidi itself plus various neighbours in Zeos. 2008-06-17 17:06:01 +00:00

ff71f59fee Fix compiler warning 1033 by importing units (that the compiler decides to import automatically anyway). 
Note that PngComponentsD110 builds correctly without PNG or PngComponents built, for some reason, unlike the other runtime/designtime packages.

ee1feb5521 Reimplement ANSI support to keep nutcases armed with v3.23 mysql servers happy. 
Fixes issue #497.

ec7e5cf2c2 Fix: only assume that UTF-8 size estimates are in effect if the character set is UTF-8. (Couldn't be bothered to find out where to actually look up the collation codes, so for now just assumes UTF-8 when it's not binary.) 2008-06-16 19:27:47 +00:00

d21f0c50b7 * Bugfix: could have sworn that I saw the fields max width at 755 for a varchar(255) column at some point; testing now it seems that the display size is returned as a character count. Fixes issue #549, issue #547. 
* Comments updated.

2ed4507666 Code cosmetic: Sanitize NODETYPE_BASETABLE constant from superflous "BASE" 2008-06-14 12:48:04 +00:00
rosenfield.albert
c265dd2f94 Workaround: make Zeos work with less imaginative column names. Fixes issue #545. 
Extremely imaginative names can still fail (think ZEOS_RESERVED etc).

505cf7b443 Cosmetic: Keep the 'Bytes' variable counting length without the null terminator (shuffle around some +1's). 
Bugfix: Delphi 2007's Utf8ToUnicode malfunctions and causes an access violation when given a 1-byte UTF8 buffer containing only the null terminator.
 2008-06-13 13:54:10 +00:00

4b37671f18 * Bugfix: Zeos expects ColumnInfo.Precision to designate the number of characters, until now the Zeos MySQL driver stored the number of bytes instead. Fixes issue #498 and issue #261, possibly issue #339 too. 
* Bugfix: Forgot to switch from ANSI to Unicode strings here and there.  Sort of annoying that you cannot cause automatic Wide->Ansi conversion to just assert with an exception with an option.  Could perhaps modify the VCL to do it.

f880e3b21b * Poke around with a stick in Zeos, trying to fix some more Unicode issues. 
* Add "assertions" (well, small logic bombs that will explode in your face, rather) in places that I couldn't be bothered to fix or couldn't figure out.

* Zeos doesn't do anything terribly intelligent with it's row buffer, it simply stuffs columns into it from one end until it overflows.  Instead of actually fixing this by, I dunno, mapping the smallest columns into the buffer first and stopping when it's full, just decreased the threshold at which ZMySQL declares something to be a stream rather than a string.

1e31edc0c0 Sanity check: assert that row buffer length is not exceeded at a proper time, instead of dereferencing a broken pointer later on, which has random consequences (given that range checking is off). 2008-05-27 14:16:36 +00:00

3a05545dc7 Fix compiler warning by removing unused variable (from r1381). 2008-05-13 23:34:18 +00:00
rosenfield
7586134572 * Bugfix: in order to get SQL statements all the way into the stomach of the Zeos MySQL driver (aka TZMySQLStatement.Execute()), make sure that there are no characters lost via conversions from WideString to String on the way. 
* Also update other drivers so they still compile, now using the WideString interfaces.  Haven't Unicode-enabled any of them, just inserted an explicit cast from 16-bit to 8-bit strings in their respective Execute() methods.

cb18638372 Bugfix: Delphi's DB.pas::TWideStringField.SetAsWideString() puts a PWideChar into the buffer before calling this, so deserializing it as a PWideString is probably wrong. 2008-05-13 19:39:29 +00:00

72c5d3f415 Add preliminary Unicode support. 
(Requires a newer libmysql.dll, so you may want to get the strict_dll patch which is not in Zeos AFAIK.)

d4c32d56d7 Implement a completely new user manager (look + feel + logic): 
- Accounts and existing privileges are presented in a pulldown which makes it as easy to use as a toy
- Adding privileges calls the new SelectDBO dialog which is basically a tree like childwins dbtree
- Updating accounts canonicalizes various odd/legacy mechanisms in the MySQL user system
- Fullfills feature request #1547437 (btw)
- Wants to be tested heavily on different servers

A result of a team work. 1000 thanks to rosenfield for the admin friendly logic implementation, tons of fixes and usability ideas.

bba3d2afc1 Implement option to prefer SHOW TABLES over SHOW TABLES STATUS, as discussed on the mailing list. Fix relevant AVs and detection of VIEW/BASETABLE in GetDBObjectType (at least for 5.0.2+ servers). 2008-04-11 19:23:47 +00:00

8226fae2be Kill option to manually specify value of initial limit (DataLimitEnd) in preferences. Keeping the checkbox for autocalculating while rephrasing its caption. Now the limit number is set either automatically by GetCalculatedLimit() or not at all if the option is disabled. (Un-)checking the CheckboxLimit in Mainform now toggles this option permanently. 2008-03-24 00:11:38 +00:00

f64daf6917 New feature: VIEW editor, can create and edit views. Rather a simple dialog with only the most important options on it. The toolbuttons on mainform are partly moved around, that's the reason for the myriad of changes there. 2008-03-19 21:20:28 +00:00

de12c10721 Refactor Maintenance dialog to fullfill reasonable user wishes in bug #1865477 : 
- Rename components with reasonable names
- Use caching mechanism from Childwin.FetchDBTableList to fill tables listbox
- Make form resizable, store and restore customized dimensions
- Keep form instance alive and recycle that instance as long as Mainform lives
- Fix confusion with action item (wasn't really used in both menuitems)
- Add documentation

112ea167a5 Add basic support for views, without changing too much GUI logic: 
- Give them their own icon in dbtree and ListTables
- Disable pure table actions (like "Alter table", "Optimize" etc.) in context menus when a view is selected
- Add new column in ListTables: "Type" which is filled either with "Base table" or "View"
- Introduce new property "NodeType" in TVTreeData record, used currently to store NODETYPE_VIEW or NODETYPE_TABLE. This new property is meant to be used for various purposes in other VirtualTrees in the future.
- Introduce Childwin.SelectedTableType, corresponding to Childwin.SelectedTable
- Make DropTable action fit for also dropping views (and surely a list with a mixture of views and tables)
- Don't fetch rowcount from views in DisplayRowCountStats to fix bug #1844952

7e4bfafbe1 Fix access violation in Database tab when at least one view exists: TField.AsFloat on a NULL value throws this AV. User report can be found here: http://www.heidisql.com/forum/viewtopic.php?p=1812 2008-02-27 20:17:04 +00:00

b584aa5ae4 Introduce automatism for calling the updatecheck dialog. User can set the interval how often this is done in preferences dialog (default interval: 3 days, can be completely disabled). The automatic calling of this dialog should not disturb anyone as it's closed immediately if there are no updates available or if a developer version with an unknown revision is used. 
Some GUI controls on the dialog had to be moved around as well as some lines of code so everything works well with the automatic dialog closing.

4e23728aa2 - Move all hardcoded preferences names (registry) plus their default values to const.inc to fix inconsistencies like the one described here: http://www.heidisql.com/forum/viewtopic.php?p=1739 
- Consequently use Mainform.GetRegValue() to read these values, an overloaded method with either Boolean, String or Integer result. These methods keep a global TRegistry object (regMain) open while the application runs, rather than creating a new one for each caller.
- Remove Mainform.SaveRegValue() which was used in one or two callers. Rather use a TRegistry object and do that by hand. There's no significant advantage in using a SaveRegValue method currently.
