四十二天學(xué)會英語的模范短文 (2)

1、VB編程的八個優(yōu)良習(xí)慣1、“&“替換““2、變量命名大小寫，語句錯落有秩，源代碼維護(hù)方面3、請養(yǎng)成以下的“對象命名約定”良好習(xí)慣4、在簡單的選擇條件情況下使用IIf()函數(shù)5、盡量使用Debug.Print進(jìn)行調(diào)試6、在重復(fù)對某一對象的屬性進(jìn)行修改時，盡量使用With....EndWith7、MsgBox中盡量使用消息圖標(biāo)，這樣程序比較有規(guī)范8、在可能的情況下使用枚舉1、“&“替換““在很多人的編程語言中，用“”來連接字符串，這樣容易導(dǎo)

2、致歧義。良好的習(xí)慣是用“&”來連接字符串.不正確:DimsMessageAsStringsMessage=“1““2“正確:DimsMessageAsStringsMessage=“1“&“2“注意：“&“的后面有個空格2、變量命名大小寫，語句錯落有秩，源代碼維護(hù)方面下面大家比較一下以下兩段代碼:讀懂難度很大的代碼：DimSNAMEAsStringDimNTURNAsIntegerIfNTURN=0ThenIfSNAME=“vbeden
