How to create transparent bitmap

[s196675m]

I am trying to create a 16x16 bitmap resource using resource edition and then load this bitmap to a button (property set to bitmap).

My problem is bitmap has white background by default in the resource editor and this background also appear in the button. I want my drawing only will appear on the button not the button image background.

If I use ICON then icon background does not appear which is ok for me but I can not select 16x16 icon to the button, it always appear the big icon in the button.

Either I should be alble to load 16x16 icon loaded to the button or bitmap should be tranparent.
I tried using opaque option in the image toolbar without any result.

Can anybody help me to describe how to load bitmap in the button without the bitmap background.

Or how I can load small icon only in the button?

Thank you
I will appreciate your answer.
Thank you

I like to use this button class. It had the options I needed and saved me having to write it myself.

If you draw the button yourself, you can use TransparentBlt .
