如何编写BLOB代码？ [英] How to code for BLOB ?

问题描述

我正在为一名学生提供一张数据类型为BLOB的现场照片。



现在我想在桌面上执行添加/删除/修改操作但我不喜欢我不知道如何处理BLOB，因为我对这种数据类型一无所知。



一件重要的事情是需要使用vb6插入图片。



我尝试了一些非常糟糕的代码，例如：

I am having a table student with one field pics of data type BLOB.

Now I want to perform operations add/delete/modify on table but I don''t know how to deal with BLOB because I haven''t any idea about this data type.

One important thing is picture needs to be inserted using vb6.

I tried some very poor code for it like:

<br />
Private Sub IMAGE()<br />
Dim FILE As String<br />
FILE = App.Path ''path_name''<br />
If Picture1.Picture = Empty Then<br />
Open FILE For Binary Access Read As #1<br />
Get bytes<br />
rs("pics")<br />
<br />
End If<br />
End Sub<br />
<br />

你能帮帮我.........

Can you please help me.........
