<title>1. Introduction</title>
<para>
The information provided herein is based on the DLL version
4.72 which is included in MS Internet Explorer 4.01.
</para>
<para>
All information about common controls should be collected in this document.
</para>
<para>
All Wine programmers are encouraged to add their knowledge to this document.
</para>
</sect2>
<sect2>
<title>2. General Information</title>
<para>
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.
</para>
<sect3>
<title>2.1 Structure sizes of different common control versions</title>
<para>
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
<filename>COMCTL32.DLL</filename> versions. The following
list shows the structure size constants that are currently
defined in the original <filename>COMCTL32.DLL</filename>.
</para>
<note>
<para>
Some stuctures are NOT defined in wine's COMCTL32 yet.

<sect3>
<title>5.1 Dynamic Storage Array (DSA)</title>
<para>
The DSA functions are used to store and manage dynamic
arrays of fixed size memory blocks. They are used by
<filename>TASKMAN.EXE</filename>, Explorer, IE4 and other
Programs and DLL's that are "parts of the Windows
Operating System". The implementation should be complete.
</para>
<para>
Have a look at the source code to get more information.
</para>
</sect3>
<sect3>
<title>5.2 Dynamic Pointer Array (DPA)</title>
<para>
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.
</para>
<para>
Have a look at the source code to get more information.

You see, much work has still to be done. If you are

like to fix bugs or add some functionality send an e-mail to
the author of the control.
