Second off, thanks Felsiandria for the intervention. I'm tired of all the language flame wars!
OK, to the business at hand. Could you post the relevent code so we can see what you're doing? Also, Have you considered using DirectX? Transparency isn't a problem with DirectDraw.

'sets the file type
Extension = ".bmp"
'loads the picture of the arena
frmGame.Picture _ = LoadPicture_
("F:\Students\malonec_.__\" _
& ChosenArena & Extension)
imgPlayer1.Visible = False
imgPlayer2.Visible = False
'these two lines set the picture property of 'the two image boxes
imgPlayer1.Picture _
= LoadPicture _
("F:\students\malonec_.__\" & Player1_
& Extension)
imgPlayer2.Picture _
= LoadPicture _
("F:\students\malonec_.__\" & Player2 _
& Extension)
'These lines of code position the image 'boxes in the correct position for the arena 'they are playing in
imgPlayer1.Left = Player1_Arena_X
imgPlayer1.Top = Player1_Arena_Y
imgPlayer2.Top = Player2_Arena_X
imgPlayer2.Left = Player2_Arena_Y
'this line sets the image boxes to visible
imgPlayer1.Visible = True
imgPlayer2.Visible = True
Theirs the code. Everything works fine except for the fact that when I load the pictures of the player characters the white background behind them always shows through. I really don't want to have to resort to direct x though because my partners in computer class that are working on the game with me are having a hard enough time understanding the code as it is without adding in API's etc.
thanx

I remember that I hunted around, but to no avail -- VB3 had no innate ability to handle transparencies. If you're using VB4+, I believe you can set pictureboxes to use transparency. Otherwise, you have no choice but to call Win32 API functions.
IIRC, You have to load the bitmap into a picturebox like you're doing. set the picture box to invisible. I used a picturearraybox to hold all my animation frames, but you could just as easily put the mask and the graphic in the same bitmap or in seperate ones, whatever works easiest for you.
first blit with your mask, I believe using an AND blit. So the white areas will retain their color, and the black areas will be where your sprite goes. then blit your bitmap with OR. This method is, like VB3 itself, very slow though. I was unable to blit more than a few sprites without some fair slowdown occuring. Also note that this is VERY different from what you're probably used to; the way you're doing it the picturebox itself holds its coordinates in the .left and .top variables; with win32 blits you must keep track of it yourself, probably in an array of ints.
As for the specifics of the blit code, I unfortunately can't post any. I still have all the source for that project, but its in VB3 form files (which are binary), and I no longer own VB. I think there was an example program that came with VB that I took my technique from though.
