windows - Windows 窗口类区分大小写吗？

Question

MS 文档清晰如泥(而且类名字符串不常被引用)，我想知道 class name 是否Win32 window class实际上是区分大小写的吗？

Answer 1

它们不区分大小写。窗口类名称是字符串 ATOMS 和 according to MSDN ,

• Case is not significant in searches for an atom name in an atom table. Also, the entire string must match in a search operation; no substring matching is performed.
• The string associated with a string atom can be no more than 255 bytes in size. This limitation applies to all atom functions.
