按钮验证textbox内长度为15位或18位数字，相当于身份证的判断，求代码

private sub text1_lostfocus() if trim(text1。text)15 or len(trim(text1。text)<>18 then msgbox "请输入15位或18位身份证号！",48,"提示" text1。 setfocus exit sub end if end ifend sub==============================================='直接判断是否正确Private Function CheckCode(sCode As String) As Boolean Dim S1To17 As String, S...全部

  private sub text1_lostfocus() if trim(text1。text)15 or len(trim(text1。text)<>18 then msgbox "请输入15位或18位身份证号！",48,"提示" text1。
