1 使用api函數(shù)safearraygetdim()的返回值是否小于等于0
Private Declare Function SafeArrayGetDim Lib "oleaut32.dll" (ByRef saArray() As Any) As Long '判斷數(shù)組為空或沒有初始化
返回值值<=0,說明數(shù)組元素個數(shù)為0或者數(shù)組還沒有初始化. 2 使用cstr(Join(list[, delimiter]))函數(shù)的返回值是否不等于"" 將delimiter參數(shù)設(shè)置為"" 例如:if (cstr(join(arr,""))) = "" then msgbox "arr 數(shù)組為空或者尚未初始化"
