VB - Detemine if TitleBar Gradient is Enabled

[John McKernan]

Summary:
Determines if TitleBar Gradient effect is enabled.

Please note: This code requires Win 98/ME/2k/XP. You would probably want to check for Windows version before executing this code.

'declare api functions
    Public Declare Function SystemParametersInfo Lib "user32" Alias "SystemParametersInfoA" _
        (ByVal uAction As Long, _
        ByVal uParam As Long, _
        ByVal lpvParam As Any, _
        ByVal fuWinIni As Long) As Long
 
'declare constants
    Public Const SPI_GETGRADIENTCAPTIONS = &H1008

Usage Example:

Dim bGradientEnabled as Boolean
 
bGradientEnabled = CBool(SystemParametersInfo(SPI_GETGRADIENTCAPTIONS, 0&, "", 0&))

Return Values:
Will return True if TitleBar Gradient is enabled, False otherwise.

Notes:
The declarations for API functions, constants, types and the GetRGBColors function can be moved to a module. If so, they should be declared as Public.
