vb如何将多张图片写入到一个文件中并分别调用？

使用流对象保存和显示图片
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

资源文件不行的，他会在运行中添加文件，还是用流对象保存到数据库里比较好！把tianqing20wen的再完善一下就可以了！
