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.
NOTE: 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 version 4.00.
