Arggh! Texture mapping in VB6 with OpenGL

Let me start by saying that I am rendering shaed polygons just fine, it's just when I try to put textures on that I get nothing but a black rectangle.
I wrote the following subroutine to give me a quick and easy way to put a textured rectangle to the screen. It's not very efficient, it doesn't make good use of memory, and it has extra variables from previous versions of the routine, but it's a start. Can someone please tell me what's wrong with it? TIA!

Private Sub DrawTexturedRectangle(V1 As Vector, V2 As Vector, V3 As Vector, V4 As Vector, _
strFile As String, _
Optional VnX As Single, Optional VnY As Single, Optional VnZ As Single)

'Optional returns the Normal to the last vertex
Dim Vn1 As Vector, Vn2 As Vector, Vn3 As Vector, Vn4 As Vector
Dim Vc1 As Vector, Vc2 As Vector, Vc3 As Vector, Vc4 As Vector
Dim Fill_Color(0 To 3) As Single, Line_Color(0 To 3) As Single
Dim sngColor As Single, hTexture As Long, hDC1 As Long, hBitmap

If strFile <> "" And Dir(strFile) <> "" Then
hDC1 = CreateCompatibleDC(0)
hBitmap = LoadBMP(hDC1, strFile)
If hBitmap <> 0 Then
