Question

EXCEL VBA中窗口控件复合框内输入内容时能像函数选择时那样输入首字就能显示后边的内容，并验证有效性

我想在vba窗体内的物料编码处输入代码32 就自动提示32开头的代码 ，并且内容只能是物料编码存在的编码，如果输入了列表中没有的代码，点确认按钮的时候禁止执行并提示。

Answer 1

Public n As Byte '定义全局变量

Private Sub ComboBox1_Change()
If Me.ComboBox1 = "" Then Me.ComboBox1.List = Array(""): Exit Sub
If n = 38 Or n = 40 Then Exit Sub ‘不响应“向上”及“向下”按键
Dim arr, i&, d As Object
Set d = CreateObject("scripting.dictionary")
arr = [d1].CurrentRegion
For i = 1 To UBound(arr)
If Left(arr(i, 1), Len(Me.ComboBox1)) = Me.ComboBox1 Then d(arr(i, 1)) = arr(i, 1)
Next i
Me.ComboBox1.List = d.keys
Me.ComboBox1.DropDown
End Sub

Private Sub ComboBox1_KeyDown(ByVal KeyCode As MSForms.ReturnInteger, ByVal Shift As Integer)
n = KeyCode
End Sub
