VB6 - Complete BitBlt Overview

Hi r33d3r,

Complete BitBlt Overview
Yikes! That sounds like ****! Well I won't get in to advanced since I'm quite new to BitBlt as well. (2 non-stop days of brain cracking got me my knowledge so far)
This topic will be updated with sources (for lazy people I guess, excuse me if I'm wrong ) and more questions.

!!! PLEASE DON'T REPLY, SEND ME A PRIVATE MESSAGE INSTEAD !!!

You should read this first!

So there we are workin' with masking and stuff.
Now we have some thing to watch out for!

I use BitBlt and the pictures need to be visible? Why!
No this isn't needed just do this:

Picture1.AutoRedraw = True
Picture1.Visible = False

Now BitBlt again and, see no picturebox but the BitBlt shows you what you wanted.


Masking is difficult! Is there another way to do this?
First you need to know that you COULD use masking. Though in many cases you don't need to really make things transparant. (This is a lazy way to accomplish things. ) Just equip the sprites with the unlayered tile now again this won't work in many occasions but sometimes this is just what we want and we don't need to do difficult masking.


My screen starts to flash a little every now and then (or worse )
Well this again is a AutoRedraw thing, I still can't find the use of letting this function on False but set

Picture1.AutoRedraw = True

then the flashes should've stopped.
