在声明为字符串的变量中输入不匹配的VBA错误

Question

我不明白下面的代码,请帮忙.

它继续针对变量b返回类型不匹配错误.

Dim a As Integer
Dim b As String

a = InputBox("Input the number of items", "Total Number of Items.")
b = InputBox("Which Block?", "Total Number of Items.")

Do While b <> "a" Or "A" Or "B" Or "b"
        MsgBox ("Invalid Block. Try again, Input A or B")
        b = InputBox("Which Block?", "SELECT BLOCK.")
Loop
     If b = "a" Or "A" Then
        Me.ComboBox1.List = Worksheets("Sheet1").Range("a3:a39").Value
    Else
        Me.ComboBox2.List = Worksheets("Sheet2").Range("a3:a35").Value
    End If

Answer 1

您可以使用Application.InputBox强制文本输入a和和数字输入b

使用UCASE$缩短您的测试

Dim a As Long
Dim b As String

a = Application.InputBox("Input the number of items", "Total Number of Items.", , , , , , 1)
b = Application.InputBox("Which Block?", "Total Number of Items.", , , , , 2)

Do While UCase$(b) <> "A" And UCase$(b) <> "B"
b = Application.InputBox("Which Block?", "Invalid Entry - Total Number of Items.", , , , , 2)
Loop
