Enum API Constants Save Time Coding

You can simplify Win32 APIs by using enumerated types instead of constants. When you use enumerated types, VB provides you with a list of values when you define the API in your application:

 Option Explicit' define scrollbar constants as enumerationsEnum sb	SB_BOTH = 3	SB_CTL = 2	SB_HORZ = 0	SB_VERT = 1End EnumEnum esb	ESB_DISABLE_BOTH = &H3	ESB_DISABLE_DOWN = &H2	ESB_DISABLE_LEFT = &H1	ESB_ENABLE_BOTH = &H0	ESB_DISABLE_RIGHT = &H2	ESB_DISABLE_UP = &H1End Enum

Note that you need to change the Declares to match the new Enums:

 Private Declare Function EnableScrollBar Lib _	"user32" (ByVal hWnd As Long, ByVal _	wSBflags As sb, ByVal wArrows As esb) As _	LongPrivate Declare Function _	ShowScrollBar Lib "user32" (ByVal hWnd _	As Long, ByVal wBar As sb, ByVal bShow _	As Boolean) As Long

When coding up these API calls, VB displays enumerated lists for both the wSBflags and wArrows parameters to EnableScrollBar, and displays both the wBar and bShow parameters to ShowScrollBar:

 Call EnableScrollBar(Me.hWnd, SB_BOTH, _	ESB_ENABLE_BOTH)Call ShowScrollBar(Me.hWnd, SB_BOTH, True)
