我最近在筹划做一个小小的大头贴照相的小软件!!
可我们学数据库时从来没涉及到加照片,只是加数字啊 什么的!!!!
我想请教各位高手----怎么样才能把照片加到数据库中去??????
谢谢看我的帖子!!!

打开vb6,新建工程。
添加两个按钮,一个image控件
注意:Access中的photo字段类型为OLE对象.
SqlServer中的photo字段类型为Image
.
'** 引用 Microsoft ActiveX Data Objects 2.5 Library 及以上版本
‘2.5版本以下不支持Stream对象
Dim iConcstr As String
Dim iConc As ADODB.Connection
'保存文件到数据库中
Sub s_SaveFile()
Dim iStm As ADODB.Stream
Dim iRe As ADODB.Recordset
Dim iConcstr As String

'读取文件到内容
Set iStm = New ADODB.Stream
With iStm
.Type = adTypeBinary '二进制模式
.Open
.LoadFromFile App.Path + "\test.jpg"
End With

'打开保存文件的表
Set iRe = New ADODB.Recordset
With iRe
.Open "select * from img", iConc, 1, 3
.AddNew '新增一条记录
.Fields("photo") = iStm.Read
.Update
End With

'完成后关闭对象
iRe.Close
iStm.Close
End Sub
Sub s_ReadFile()
Dim iStm As ADODB.Stream
Dim iRe As ADODB.Recordset
'打开表
Set iRe = New ADODB.Recordset
‘得到最新添加的纪录
iRe.Open "select top 1 * from img order by id desc", iConc, adOpenKeyset, adLockReadOnly

'保存到文件
Set iStm = New ADODB.Stream
With iStm
.Mode = adModeReadWrite
.Type = adTypeBinary
.Open
.Write iRe("photo")
‘这里注意了,如果当前目录下存在test1.jpg,会报一个文件写入失败的错误.
.SaveToFile App.Path & "\test1.jpg"
End With

Image1.Picture = LoadPicture(App.Path & "\test1.jpg")
'关闭对象
iRe.Close
iStm.Close
End Sub
Private Sub Command1_Click()
Call s_ReadFile
End Sub
Private Sub Command2_Click()
Call s_SaveFile
End Sub
Private Sub Form_Load()
'数据库连接字符串
iConcstr = "Provider=Microsoft.Jet.OLEDB.4.0;Persist Security Info=False" & _
";Data Source=F:\csdn_vb\database\保存图片\access图片\img.mdb"
‘下面的语句是连接sqlserver数据库的.
‘iConcstr = "Provider=SQLOLEDB.1;Persist Security Info=True;" & _
‘ "User ID=sa;Password=;Initial Catalog=test;Data Source=yang"
Set iConc = New ADODB.Connection
iConc.Open iConcstr
End Sub
Private Sub Form_Unload(Cancel As Integer)
iConc.Close
Set iConc = Nothing
End Sub

谢谢高手赐教!!
试试看!!
