當[選項明確 ] 出現在模組中時,您必須使用 Dim、 Private、 Public、 ReDim或Static 語句明確宣告所有變數。 如果您嘗試使用未宣告的變數名稱,則會在 編譯時期發生錯誤。 如果您未使用Option Explicit語句,除非使用Def類型語句指定預設類型,否則所有未宣告的變數都是Variant類型。 備註 使用[明確選項 ] 可避免不正確...

Public myVariable As Integer myVariable = 10 在上述代码中,我们声明了一个名为"myVariable"的公共整型变量,并将其赋值为10。这样,在整个VBA程序中,我们都可以使用和修改这个变量的值。 声明公共变量的优势在于可以方便地在不同的模块和过程中共享数据,避免了重复定义变量的麻烦。同时,公共变量的作用域更广,可以...
