BackColor of ActiveX Controls

[awadey]

I am resizing a Control at runtime (basically creating a custom combobox). Unfortunately I need to make the background of the control transparent (so when I resize it certain sections of the control do not overlap other controls). The backstyle property does not seem to make a blind bit of difference if I set it to transparent when on a panel - Any ideas???

The alternative is to change the shape of the control to something other than a rectangle - any ideas on this either

for weird shapes, u use:

Declare Function CombineRgn Lib "gdi32" Alias "CombineRgn" (ByVal hDestRgn As Long, ByVal hSrcRgn1 As Long, ByVal hSrcRgn2 As Long, ByVal nCombineMode As Long) As Long
