Use of Cards.dll in VB.NET

hi, i am making a card game in vb.net and need some help getting the cards to display. this is what have gathered so far

    Declare Function cdtInit Lib "Cards.Dll" (ByVal dx As Long, ByVal dy As Long) As Long

    Declare Function cdtDrawExt Lib "Cards.Dll" (ByVal hdc As Long, ByVal X As Long, ByVal Y As Long, ByVal dx As Long, ByVal dy As Long, ByVal ordCard As Long, ByVal iDraw As Long, ByVal clr As Long) As Long

    Declare Function cdtDraw Lib "Cards.Dll" (ByVal hdc As Object, ByVal X As Long, ByVal Y As Long, ByVal iCard As Long, ByVal iDraw As Long, ByVal clr As Long) As Long

    Declare Function cdtTerm Lib "Cards.Dll" () As Long

after setting up the cards.dll, so to exactly draw the card, i need the following

cdtDraw(me.hdc, 100, 100, 4, 0, 1), the trouble is with the me.hdc part
it works in vb6 but not dot net

i have a picturebox and want to be able to draw the windows cards in it.

any help would be great thanks guys
