主题：DateTimePicker的ValueChanged

 如果你的表是外部表，你的数据库是sqlserver，你要把#改成单引号'

 如果还报错，就是日期格式问题，AfterOpenProject写代码

Dim cd As System.Globalization.DateTimeFormatInfo = System.Globalization.DateTimeFormatInfo.CurrentInfo
cd.ShortDatePattern = "yyyy年MM月dd日"
Dim DateInfo As System.Reflection.FieldInfo = cd.Gettype.GetField("generalLongTimePattern", System.Reflection.BindingFlags.NonPublic Or System.Reflection.BindingFlags.Instance)
If  DateInfo IsNot Nothing Then
    DateInfo.SetValue(cd, "yyyy-MM-dd HH:mm:ss")
End If
