Hey Izy Coder ,
Yeah, Imformas has a point. Also, I believe this can be answered with a simple Googley search: www.google.com.au/search?q=custom+drawn+tabs+vb.net&sourceid=opera&ie=UTF-8&oe=UTF-8

Hope this helps!

Izy Coder you pretty much did "As the title say.
with dll."

Really?. oh okay

Ok basically create a class that inherits from a tabcontrol


Public Class CustomTabControl
  Inherits TabControl

End Class


Then overwrite the OnPaint sub.


Public Class CustomTabControl
  Inherits TabControl

  Protected Overrides Sub OnPaint(e as PaintEventArgs)

  End Sub

End Class



In the TabControl class, there is a method called GetTabRect(index as Integer) that returns a rectangle based on the a tab at a certain index.

So, you can loop through the TabPages and use Graphics to fill a rectangle retrieved by the GetTabRect function.
This way you can draw a image or whatever.

Basic outline (I'll let you figure the rest out)


Public Class CustomTabControl
  Inherits TabControl

  Protected Overrides Sub OnPaint(e as PaintEventArgs)
      For i=0 to TabPages.Count -1
        If SelectedIndex = i Then
           e.Graphics.FillRectangle(Brushes.White,GetTabRect(i))
        Else
           e.Graphics.FillRectangle(Brushes.WhiteSmoke,GetTabRect(i))
        End if  
      Next
  End Sub

End Class


Then you can use

e.graphics.drawrectangle()
and
e.graphics.drawstring()

to draw the tab's text or draw a border.
