如何检查哪些数据发送到数据库

在我的表单中，我有一个与数据库(mydatabase.mdb)的连接，在我的表单中，我想提交一个日期.

我使用绑定到该字段的DateTimePicker.

如果我在程序提交之前检查DateTimePicker的.Value或.Text不是Null，则程序表示不是.
因此它提交了记录，但是如果我回头看该记录，则该字段为Null.

希望有人能帮助我.

Hi,

In my form I have a connection to my database (mydatabase.mdb) and in my form I want to submit a date.

I use a DateTimePicker that is bind to the field.

If i check, before the program submit, the DateTimePicker''s .Value or .Text isn''t Null, the program says that it isn''t.
So it submits the record, but if I look back at the record the field is Null.

Hope someone can help me.
