'Usage
 
Dim instance As TwainDevice
Dim capability As Capability
Dim index As Integer
Dim value As String
 
value = instance.GetCapabilityConstantDescription(capability, index)

public string GetCapabilityConstantDescription( 
   Capability capability,
   int index
)

public: string* GetCapabilityConstantDescription( 
   Capability capability,
   int index
) 

public:
String^ GetCapabilityConstantDescription( 
   Capability capability,
   int index
) 

Parameters

capability

A Capability.

index

The index of the Capability constant.

Return Value

When the capability type is TWCAP_ENUM, the Source may return a list of constants that signify settings.

For example, if Capability = ICAP_PIXELTYPE, and the Source returns a TWCAP_ENUM containing the constants, TwptBW (0), TwptGray (1), TwptRgb (2) a description of each may be obtained with the GetCapabilityConstantDescription method.

TwainPRO.GetCapabilityConstantDescription( Capability.IcapPixelType, (System.Int32)CapabilityConstants.TwptBW ) would return "Black and White". This can be used for filling a listbox or combobox with descriptions of available values instead of just the constants.
