Transparency in .png files

[Guest]

I wonder if you can make .png images more transparent when drawing them using
GDI+? If it is possible, how can I do? I have tried the example at
http://www.leunen.com/cbuilder/gdiplus.html, but the image disappears
completely instead.

what do you mean with "more transparent"?
you want to control the alpha channel?
