1. How to change 'Twip' to 'Pixel'? I'm rather difficult to
   program in 'twip'. I have change ScaleMode property to Pixel
   but the Height and Width of my form is still in Twip format.
2. How to make a transparent button?
3. I want to make a database which contains:
   * 1 field for the word -> type: character
   * 1 field for the voice -> type: Wave
   * 1 field for the picture -> type: BMP
   the questions are:
   a. What type should I choose in MDB format for Wave and BMP?
   b. How can I take the Wave and BMP data programmatically and
      show it (for BMP) or to play it on (for the Wave).

Thank you for the attention.
As usual, a stupid newbie needs a help...

1 - Learn to live with twips.

2 - Standard buttons don't allow transparent. Maybe a 3rd party control can.

3a - Don't store pictures in a DB. Instead store the file name string or whole path string if they are scattered. Then look up filename and keep your pictures in on disk - safer and easier to work with.

3b - Look up the Multi media control in the VB help - it's simple to use. It will do both waves and graphics.

Stinger: You cannot convert Twip to pixel because there are 1440 Twips per inch which ensures the same relative positioning on any screen resolution. Pixels are "fixed" so if you have a form (for example) that you set to 600 pixels wide, it will overlap in 640 x 480 screen mode. But using twips it will be easier to scale on any screen resolution.

Also the standard button does not allow setting font color. If you use another 3rd party button BEWARE : the nightmare of converting your project when a new version of VB comes out and you either have to buy an updated 3rd party control or worse : there is no update - you have a mess to "fix". I have suffered this too many times in the past. So : Unless absolutely necessary avoid them!
