第1章 Visual Basic 6.0程序設(shè)計概述一、判斷題1 23 說明：同類控件（如兩個標(biāo)簽）相互重疊，設(shè)計時可以設(shè)置“置前”、“置后”屬性。4 5 6 7 8 9 10 11 1213 14 15 16 17 18 19 20二、選擇題1. C 2.

Width Text1.Height = Form1.ScaleHeight/2 用 Form1.ScaleHeight優(yōu)于用Form1. Height Command1.Top = Form1.ScaleHeight - Command1.Height Command1.Left = Form1.ScaleWidth - Command1.WidthEnd Sub第2章 程序設(shè)計基礎(chǔ)一、判斷題1 2 3 4 5 6 7 8 9 10二、選擇題1B 2D 3A 4C 5C 6B 7A 8D 9.
