Constants module

The VBRUN Constants module collects the named-integer enumerations that classic VB6 forms, intrinsic controls, and runtime services use to spell out their option values — colours, mouse pointers, key codes, drag/drop states, OLE container behaviour, printer setup values, and so on. There are no standalone constants in this module; everything is grouped into an enumeration so that IntelliSense can offer the right options at each property or argument.

Some enumerations are tagged [MustBeQualified] in the source — their members must be referenced through the enum name (e.g. ControlBorderStyleConstantsCustom.vbCustomBorder) to avoid clashing with members of similarly named enumerations. This is noted on those enum’s pages.

Enumerations

Note

The enumeration name StorageTypeContants (note the missing s) is preserved here exactly as the runtime exposes it; the misspelling is a long-standing VB6 holdover.
