好吧,這是我從這個網站使用的代碼。一切工作正常,但我需要一點點不同的代碼上傳圖片,我不知道該怎麼辦 - 這裏的代碼 -從vb.net上載圖像文件在sql server 2008中卡住代碼
Private Sub btnAttach_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles btnAttach.Click
Dim iLength As Integer = CType(File1.PostedFile.InputStream.Length, Integer)
If iLength = 0 Then Exit Sub 'not a valid file
Dim sContentType As String = File1.PostedFile.ContentType
Dim sFileName As String, i As Integer
Dim bytContent As Byte()
ReDim bytContent(iLength) 'byte array, set to file size
'strip the path off the filename
i = InStrRev(File1.PostedFile.FileName.Trim, "\")
If i = 0 Then
sFileName = File1.PostedFile.FileName.Trim
Else
sFileName = Right(File1.PostedFile.FileName.Trim, Len(File1.PostedFile.FileName.Trim) - i)
End If
Try
File1.PostedFile.InputStream.Read(bytContent, 0, iLength)
With cmdInsertAttachment
.Parameters("@FileName").Value = sFileName
.Parameters("@FileSize").Value = iLength
.Parameters("@FileData").Value = bytContent
.Parameters("@ContentType").Value = sContentType
.ExecuteNonQuery()
End With
Catch ex As Exception
'Handle your database error here
dbConn.Close()
End Try
Response.Redirect(Request.Url.ToString) 'Refresh page
End Sub
一切正常,當涉及到這部分除了 -
With cmdInsertAttachment
.Parameters("@FileName").Value = sFileName
.Parameters("@FileSize").Value = iLength
.Parameters("@FileData").Value = bytContent
.Parameters("@ContentType").Value = sContentType
.ExecuteNonQuery()
End With
我沒有這些參數。我只有1個字段在sql server表中,表示Img並且有圖像數據類型。我如何使用此代碼使用此插入語句在db中獲取映像? insert into table1(img)values(???)
