Summary:
Resource script statements are documented in Chapter 8 of the
"Microsoft Windows Software Development Kit Reference Volume 2." This
chapter includes a discussion of button controls and the following
statement on page 8-24:
In addition to these styles, the style field may contain any
combination (or none) of the BUTTON-class styles described in Table
8.3, "Control Styles." Styles can be combined using the bitwise OR
operator.
This statement, which is repeated a number of times throughout the
chapter, is incorrect; button styles cannot be combined.
More Information:
The button style identifiers (BS_*) are defined in the WINDOWS.H file
as consecutive integers, not individual bits. If two button styles are
combined and the combination creates a legal button style, the button
will be created with that style. However, if two button styles are
combined and the combination does not create a legal button style, the
button will be created, but will not be painted on the screen.
Microsoft has confirmed this to be an error in version 3.0 of the
Windows Software Development Kit (SDK) documentation.
