Visual Basic, I learned, does not use SI units of length. It uses a twip, which is one twentieth of one point. There being 72 points to an inch, a twip is 1/20 of 1/72 of 25.4 mm, or 17.64 um. -- Paul Trusten, R.Ph. 3609 Caldera Boulevard, Apt. 122 Midland TX 79707-2872 USA (915)-694-6208 [EMAIL PROTECTED]
