TooolbarButton transparency. A proposal of solution

[normatec]

The proposal is to acquire at runtime from the registry the color of the toolbar and use it to replace the 0.0 pixel color of the bitmaps of an ImageList.
I hope it is useful

Sub Globals
Dim Type (R,G,B) color
Dim binary(0) As Byte

Sub App_Start
' ...
' ...
if cPPC = True Then
' acquire the color...
reg.New1
reg.RootKey(reg.rtLocalMachine)
key = "System\GWE"
binary() = reg.GetValue(key,"SysColor")
RegOrder = 15 ' position of the BtnFaceColor (used by the toolbar)...
color.R = binary((4 * RegOrder)+0)
color.G = binary((4 * RegOrder)+1)
color.B = binary((4 * RegOrder)+2)
' replace the color...
For i = 0 To ImageList1.Count - 1
bitmap1.New3 (ImageList1.Item(i))
color0_0 = bitmap1.GetPixel1 (0, 0)
For x = 0 To bitmap1.Width -1
For y = 0 To bitmap1.Height -1
If bitmap1.GetPixel1 (x, y) = Color0_0 Then
bitmap1.SetPixel(x, y, Rgb (color.R,color.G,color.B))
End If
Next
Next
ImageList1.Item(i) = bitmap1.Value
Next
End If
' now we create the toolbarbuttons...
bar.New1("FormXXXX")
btn1.New1
bar.AddToolBarButton(btn1.Value)
btn1.Style = btn1.stToggleButton
bar.AddImage2(ImageList1.Item(0))
'...

normatec nice method!
but it doesn't work with WisBar... may be in future Erel do real transparent...i'm see it in c#
