[DirectX 8] Error

[Hellomy]

My error: Something about variable block set.
My error line: the line that has " 'error " on it.
My Code:

Dim Dx As DirectX8
Dim D3d As Direct3D8
Dim D As D3DX8
Dim D3DDevice As Direct3DDevice8
Dim MainFont As D3DXFont
Dim MainFontDesc As IFont
Dim TextRect As RECT
Dim fnt As New StdFont
Dim TextToDraw As String
 
Public Sub DrawText(Text As String, X As Long, Y As Long)
    fnt.Name = "Verdana"
    fnt.Size = 18
    fnt.Bold = True
    Set MainFontDesc = fnt
    'Error Set MainFont = D.CreateFont(D3DDevice, MainFontDesc.hFont)
    TextRect.Top = 1
    TextRect.Left = 1
    TextRect.Bottom = Y
    TextRect.Right = X
    D3DDevice.BeginScene
    D.DrawText MainFont, &HFFCCCCFF, Text, TextRect, DT_TOP Or DT_CENTER
    D3DDevice.EndScene
    D3DDevice.Present ByVal 0, ByVal 0, 0, ByVal 0
End Sub
 
Public Sub Init()
    Dim DispMode As D3DDISPLAYMODE
    Dim D3DWindow As D3DPRESENT_PARAMETERS
    Set Dx = New DirectX8
    Set D3d = Dx.Direct3DCreate()
    D3d.GetAdapterDisplayMode D3DADAPTER_DEFAULT, DispMode
    D3DWindow.Windowed = 1
    D3DWindow.SwapEffect = D3DSWAPEFFECT_COPY_VSYNC
    D3DWindow.BackBufferFormat = DispMode.Format
    Set D3DDevice = D3d.CreateDevice(D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL, Client.hwnd, D3DCREATE_SOFTWARE_VERTEXPROCESSING, D3DWindow)
End Sub
