Bitlblt is faster when using the .image property of picture box control with paintpicture.  Under Windows XP, Bitblt out performs PaintPicture using either property.=== PictureBox: Picture Box Control ===  pMainShip.Picture = LoadPicture(Trim(App.Path) & "\" & "sc001.bmp")=== Steps to Smooth Animation ===''Summary:''# Load Images (Mask and Sprite)## Load into PictureBox then use BitBlt -or-## Load into memory DC then use BitBlt (less memory, time, and resource)# Oscillator## Use a Timer Control -or-## Throttle technique (looping continously)# Place the Mask (2 color)# Place the Sprite Raster Image (visible part of image)# Me.Refresh## Optional use Back Buffer (flickers more on small images)## Optional use StretchBlt to resize Sprite
