Simple when you know

I don't seem to have an image control only picturebox
Is there one in .NET ???

Image controls were made obsolete with .NET and GDI+. Use the Picturebox. (Actually, you really don't even need that if you create your images in memory!)

how do i do that
I have an image which in vb i dont see the back white
in vb.net like this eee is VB image ddd is VB.NET.picturebox

Set the TransparencyKey to Color.White (assuming that the transparent background is exactly white - &HFFFFFF)

its not a property, is it possible at runtime ???

My mistake, I was assuming you were drawing directly to a form. Instead, you will need to create a graphics object and use MakeTransparent:

Dim g As Graphics = PictureBox1.CreateGraphics()
Dim b As Bitmap = New Bitmap("YourFileName")
b.MakeTransparent(Color.White)
'
PictureBox.Image = b

Thanks

C:\AMPS\DotNET\Solitaire\frmSolitare.vb(364): 'MakeTransparent' is not a member of 'System.Drawing.Bitmap'.
got this error
any ideas ?

What version of .NET are you using? Works fine for me with .NET Framework 1.0
