Wine Builtin DLLs
A more detailed look at Wine's builtin DLLs...
Common Controls
Their development status and their UNDOCUMENTED features and functions
written by Eric Kohl <ekohl@abo.rhein-zeitung.de>
(Extracted from wine/documentation/common_controls)
1. Introduction
The information provided herein is based on the dll version
4.72 which is included in MS Internet Explorer 4.01.
All information about common controls should be collected in this document.
All Wine programmers are encouraged to add their knowledge to this document.
2. General Information
Further information about common controls can be found in
the MS Platform SDK and the MS Internet Client SDK (most
recent). Information from these SDK's will NOT be repeated
here. Only information which can NOT be found in these SDK's
will be collected here. Some information in the SDK's
mentioned above is (intentionally???) WRONG. Corrections to
wrong information will be collected here too.
2.1 Structure sizes of different common control versions
The common controls have been continously improved in the
past. Some of the orignal structures had to be extended
and their size changed. Most of the common control
structures include their size as the first parameter. If a
control gets the wrong size in a message or function a
failure is very likely to occur. To avoid this, MS defined
new constants that reflect the structure size of older
COMCTL32.DLL versions. The following
list shows the structure size constants that are currently
defined in the original COMCTL32.DLL.
Some stuctures are NOT defined in wine's COMCTL32 yet.
HDITEM_V1_SIZE:
The size of the HDITEM
structure in version 4.00.
LVCOLUMN_V1_SIZE:
The size of the
LVCOLUMN structure in
version 4.00.
LVHITTESTINFO_V1_SIZE:
The size of the
LVHITTESTINFO structure in
version 4.00.
LVITEM_V1_SIZE:
The size of the LVITEM
structure in version 4.00.
NMLVCUSTOMDRAW_V3_SIZE:
The size of the
NMLVCUSTOMDRAW structure in
version 4.70.
NMTTDISPINFO_V1_SIZE:
The size of the
NMTTDISPINFO structure in
version 4.00.
NMTVCUSTOMDRAW_V3_SIZE:
The size of the
NMTVCUSTOMDRAW structure in
version 4.70.
PROPSHEETHEADER_V1_SIZE:
The size of the
PROPSHEETHEADER structure
in version 4.00.
PROPSHEETPAGE_V1_SIZE:
The size of the
PROPSHEETPAGE structure in
version 4.00.
REBARBANDINFO_V3_SIZE:
The size of the
REBARBANDINFO structure in
version 4.70.
TTTOOLINFO_V1_SIZE:
The size of the
TOOLINFO structure in

Some minor changes by Eric Kohl <ekohl@abo.rhein-zeitung.de>.
Status:
Unknown.
Notes
Have a look at controls/updown.c
for a list of bugs and missing features.
The status is unknown, because I did not have a close
look at this control. One test-program looked quite
good, but in Win95's cdplayer.exe
the control does not show at all.
Any volunteers??
4. Additional Information
Has to be written...
5. Undocumented features
There are quite a lot of undocumented functions like:
DSA (Dynamic Storage Array) functions.
DPA (Dynamic Pointer Array) functions.
MRU ("Most Recently Used" List) functions.
other unknown functions.
Have a look at relay32/comctl32.spec.
5.1 Dymnamic Storage Array (DSA)
The DSA functions are used to store and manage dynamic
arrays of fixed size memory blocks. They are used by
TASKMAN.EXE, Explorer, IE4 and other
Programs and DLL's that are "parts of the Windows
Operating System". The implementation should be complete.
Have a look at the source code to get more information.
5.2 Dynamic Pointer Array (DPA)
Similar to the DSA functions, but they just store
pointers. They are used by Explorer, IE4 and other
Programs and DLL's that are "parts of the Windows
Operating System". The implementation should be complete.
Have a look at the source code to get more information.
5.3 "Most Recently Used" - List (MRU)
Only stubs are implemented to keep Explorer from bailing out.
No more information available at this time!
5.4 MenuHelp
Has to be written...
5.5 GetEffectiveClientRect
Has to be written...
5.6 ShowHideMenuCtl
The official documentation provided by MS is incomplete.
lpInfo:
Both values of the first pair must be the handle
to the applications main menu.
5.7 Other undocumented functions
Several other undocumented functions are used by IE4.
String functions: (will be written...)
6. Epilogue
You see, much work has still to be done. If you are
interested in writing a control send me an e-mail. If you
like to fix bugs or add some functionality send an e-mail to
the author of the control.
