推荐答案
我不确定这是一个答案，但如果你使用ASCII字符映射来获得
合法的字母和数字，这将是一种方法。
我无法帮助你不仅如此。

I''m not sure this is an answer, but if you use the ASCII character maps for
legal letters and numbers that would be a way to do this.
I can''t help you anymore than that.

我在供应商短名称中所做的事情我不允许使用特殊字符
来帮助搜索是使用KeyPress事件，例如
（编辑为简洁）
Private Sub txtShortname_KeyPress（KeyAscii As Integer）
Dim strchar As String
Dim strNoShortName As String
strNoShortName ="，。？/ \？`！"£
what I do in my supplier shortname where I disallow special characters
to aid searching is use the KeyPress event, e.g.
(edited for brevity)
Private Sub txtShortname_KeyPress(KeyAscii As Integer)
Dim strchar As String
Dim strNoShortName As String
strNoShortName = ",.?/\?`!"￡
