In Windows programming, there are a lot of strange data types, beginners do not know what these represent, the following data types are listed as follows: Atom Atom (Reference to a string in an atomic table) bool Boolean variable boolean boolean variable byte byte (8-bit) CChar Windows character char Windows character COLORREF red, green, blue (RGB) color value (32-bit) Const variable, the value of the variable remains constant during execution critical_section critical segment Object Ctryid country identifier Dlgproc Pointer to a dialog box procedure DWORD double Word (32-bit) Enhmfenumproc pointer to an application-defined callback function that enumerates the enhanced metafile records Enumreslangproc a pointer to an application-defined callback function. The callback function enumerates the resource languages. Enumresnameproc Pointer to an application-defined callback function that enumerates the resource names. Enumrestypeproc Pointer to an application-defined callback function that enumerates the resource types.
