Alpha blended non rectangular form in VB6

[LaVolpe]

Unfortunately, drawing on bitmaps with the alpha-channel in play is not straightforwared and does have a learning curve. The basics should be addressed first. Here are some things you will have to read up on to begin with
1. Learn how to create/use/destroy a memory DC
2. Learn how to create/use/destroy a memory bitmap
3. If not using GDI+, learn how to premultiply RGB values against the Alpha value
4. If using GDI+, learn how to use GDI+ for basic drawing and for drawing strings

After you are comfortable with the above, then providing examples would be more meaningful. Drawing controls onto the 32bit bitmap is a bit complicated but doable.

Here is a site that has good info on bitmaps in general and basics on manipulating them. 32bit bitmaps for alpha-channel processing are not addressed, but the site has some very good basics.

You also may want to look at some of these examples on planetsourcecode.

Edited: Searching this forum and googling for "UpdatedLayeredWindow" and "VB6" should return even more examples.
