Do you work With DirecX3D ?
How do you draw the Square?
Where do you want to have the AlphaBlend - Transperency?

LDV
 
Dev.RenderState.AlphaSourceBlend = Blend.SourceAlpha
Dev.RenderState.AlphaDestinationBlend = Blend.InvSourceAlpha
DEv.RenderState.AlphaBlendEnable = True
in your render sub,

and then when loading your texture,

text = new texture(yourbitmap, width,height...,transparent color [see Intellisense])

sorry i dont remember of the top of my head
does that help,
pent?

edit:
does that help?
