OK…this is my internal class

[StructLayout(LayoutKind.Sequential, Pack = 2)]

internal class TwEnumeration

{

public   short   ItemType;

public   short   NumItems;

public   short   CurrentIndex;

public   short   DefaultIndex;

[MarshalAs(UnmanagedType.ByValArray, SizeConst=100)]

public short[] ItemList;

}

based in twain´s specification

---

typedef struct {

TW_UINT16 ItemType;

TW_UINT32 NumItems;

TW_UINT32 CurrentIndex;

TW_UINT32 DefaultIndex;

TW_UINT8 ItemList[1];

} 

So……when i get a certain capability (XResolution, YResolution, SupportedSize, etc. Using TwMSG.Get insted of TwMSG.Set) this property fill the capability object (capX) with the results (capX.handle)…

TwCapability capX = new TwCapability(TwCap.YResolution, TwOn.Enum  , TwType.Fix32);

rc = DScap( appid, srcds, TwDG.Control, TwDAT.Capability, TwMSG.Get, capX);

if( rc != TwRC.Success )

{

CloseSrc();

return array;

}

note : capX.handle is only that: a HANDLER!!!!! jejej
