很多兄弟在這裡問關於VB6讀寫數據庫中的圖片的問題，在此有一例，希有所啟發。
1，以人名和相關圖片為例說明，數據庫為Access，有如下字段：Name char,picture OLE object,FileLength Number。當為ms sql時，將picture改為lob即可。
2，示例包含control：commom dialog,picture,listbox。
源碼如下：
Option Explicit
Private Declare Function GetTempFileName Lib "kernel32" Alias "GetTempFileNameA" (ByVal lpszPath As String, ByVal lpPrefixString As String, ByVal wUnique As Long, ByVal lpTempFileName As String) As Long
Private Declare Function GetTempPath Lib "kernel32" Alias "GetTempPathA" (ByVal nBufferLength As Long, ByVal lpBuffer As String) As Long
Private Const MAX_PATH = 260
Private m_DBConn As ADODB.Connection
Private Const BLOCK_SIZE = 10000
' Return a temporary file name.
Private Function TemporaryFileName() As String
Dim temp_path As String
Dim temp_file As String
Dim length As Long
' Get the temporary file path.
temp_path = Space$(MAX_PATH)
length = GetTempPath(MAX_PATH, temp_path)
temp_path = Left$(temp_path, length)
' Get the file name.
temp_file = Space$(MAX_PATH)
GetTempFileName temp_path, "per", 0, temp_file
TemporaryFileName = Left$(temp_file, InStr(temp_file, Chr$(0)) - 1)
End Function
Private Sub Form_Load()
Dim db_file As String
Dim rs As ADODB.Recordset
' Get the database file name.
db_file = App.Path
If Right$(db_file, 1) <> "\" Then db_file = db_file & "\"
db_file = db_file & "dbpict.mdb"
' Open the database connection.
Set m_DBConn = New ADODB.Connection
m_DBConn.Open _
"Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source=" & db_file & ";" & _
"Persist Security Info=False"
' Get the list of people.
Set rs = m_DBConn.Execute("SELECT Name FROM People ORDER BY Name", , adCmdText)
Do While Not rs.EOF
lstPeople.AddItem rs!Name
rs.MoveNext
Loop
rs.Close
Set rs = Nothing
End Sub
Private Sub Form_Resize()
lstPeople.Height = ScaleHeight
End Sub
' Display the clicked person.
Private Sub lstPeople_Click()
Dim rs As ADODB.Recordset
Dim bytes() As Byte
Dim file_name As
