VB6 Controls appearing transparent over UserControl Frame

Question

I have some VB6 controls that I have placed on a frame OCX that I have created myself. The issue, is when the frames are made visible, sometimes the controls (in this example 2 comboboxes) are missing, and you can see the background color of the Form through it.

The Usercontrol, is just 2 images with gradients, and a label for the title.

Are there any settings for UserControls that I need to know about that will fix this?

EDITED

AutoRedraw: True Clip Controls: True

Answer 1

Clip Controls had to be set to False. Fixed me whole problem. Thanks for the answers though

Answer 2

1) Make sure that your container usercontrol have AutoRedraw=true and ClipControls=true

2) Add the following code to your container usercontrol:

Private Sub UserControl_Paint()
   Refresh
End Sub

Answer 3

Set your background images as

backgroundimage.zorder 1

And your controls

combobox1.zorder 0

You can do this at runtime. I think your combo boxes are pushed back behind your image in the Z-Order. This is similar to the "Bring to front" and "push to back" options you have at design time.
