hi,
I have set the transparent key property of a form to same color of backrgound of that form and I have set the border style of that form to none
I have a picture box control which I want to use it as a backgroud so I set some background image to that picture box
now I have another picture box control (which has icon or png logo) which should be transparent to the main picture box (which meant to be as background for all other controls), but the problem that is that when I make this logo picture box as tranparent, its showing nothing as a background !!
I tried to solve this to set the form's background image property to this background image, it works but the problem the back ground image here is repeated in both X and Y axis
error

When you set an item to transparent what it actually does is take on the background color of the control you have it placed on. That being said, if you have the form's background color as the transparency key and you set a controls (like your picturebox) background color to transparent, it will take on the bg color of the form and will cause the results you see there. Try just making the picturebox sizemode to auto so that it is only the size of the png in it.
If you set TransparencyKey for the form, then that color will become completely transparent, which is like boring a hole through the form, to anything that is beneath the form. If you look at the screen shot, you can see that the underlying desktop picture is showing through.
I would suggest using a color with the alpha channel set to 0. You can use the Color.FromArgb to get a color from Alpha, Red, Green, and Blue component values that range from 0 to 255.
when I set alpha to 0 its not working !!!!
this.BackColor = System.Drawing.Color.FromA
this.TransparencyKey = System.Drawing.Color.FromA
its showing the background of the png picture !!!
here is the snapshot of what happens when I set alpha channel to 0:

I want to use a tranparent form so that I can put rounded-corner picture ( which would be png type ) which also gonna be used as a background to another controls .. now all other controls should be transparent to this background png
for example ..
suppose there is a circle (or not sqaure shape) image ( e.g. msn buddy ), so the remaining part of the picture should be transparent and to the main background rounded-corner png

I believe that what you are describing is an irregularly shaped form, as in the concept of GraphicsPath and a region:

If you are using a GraphicsPath, then you should be able to get rounded corners like this:
