        <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>
        <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.

              The status is unknown, because I did not have a close

              the control does not show at all.

          <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>
            Similar to the DSA functions, but they just store

            Operating System". The implementation should be complete.

          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.
