將 jpg 保存為附件的 Excel 宏

Question

我迷失了這個話題。 我將嘗試解釋我正在嘗試做的事情： - 我的想法是能夠將 jpg 文件上傳或保存到我的 access 2010 數據庫中，此過程由 excel 中的 usign 宏啟動。 我在互聯網上閱讀了很多，但老實說我被卡住了，我找不到一個例子。 我想使用ADO連接我的想法是使用post標簽，這個標簽會有所不同，我的意思是，我想用這些圖片打印這些標簽。

您可以在下面看到我正在嘗試做的事情。 我迷路了，我得到了錯誤，也許如果有人有一個例子，我可以調整它，因為我認為，我無法使用我擁有的那個。

程序如下：

Sub SUBIRIMAGEN() 'To save a file in a table as binary


    Dim adoStream               As Object
    Dim adoCmd                  As Object
    Dim strFilePath             As String
    Dim adoCon                  As Object

    Const strServerName         As String = ""  'Server Name

    Set adoCon = CreateObject("ADODB.Connection")
    Set adoStream = CreateObject("ADODB.Stream")
    Set adoCmd = CreateObject("ADODB.Command")


    strDBName = "database1.accdb"
    strMyPath = ThisWorkbook.Path
    strDB = strMyPath & "\" & strDBName

'Connect to a data source:
'For pre - MS Access 2007, .mdb files (viz. MS Access 97 up to MS Access 2003), use the Jet provider: "Microsoft.Jet.OLEDB.4.0". For Access 2007 (.accdb database) use the ACE Provider: "Microsoft.ACE.OLEDB.12.0". The ACE Provider can be used for both the Access .mdb & .accdb files.




    '--Open Connection to SQL server
    adoCon.CursorLocation = adUseClient
    adoCon.Open ConnectionString:="Provider = Microsoft.ACE.OLEDB.12.0; data source=" & strDB
    Rem adoCon.Open "Provider=SQLOLEDB;Data Source=" & strServerName & ";Initial Catalog = " & strDB & ";Integrated Security=SSPI;"
    '----

    strFilePath = "C:\Users\pc2\Downloads\frutossecosgranel.JPG" ' File to upload

    adoStream.Type = adTypeBinary
    adoStream.Open
    adoStream.LoadFromFile strFilePath 'It fails if file is open

    With adoCmd
        .CommandText = "INSERT INTO table1 (id,attach) VALUES (?,?) " ' Query
        .CommandType = adCmdText

        '---adding parameters
        .Parameters.Append .CreateParameter("@Id", adInteger, adParamInput, 0, 1)
            .Parameters.Append .CreateParameter("@attach", adVarBinary, adParamInput, adoStream.Size, adoStream.Read)
        '---
    End With

    adoCmd.ActiveConnection = adoCon
        adoCmd.Execute

    adoCon.Close


End Sub

使用以下代碼從 excel 將圖像附加到數據庫訪問。

用excel寫下這段代碼

根據需要修改常量

 Private Sub AttachImage()
    Const dbname = "c:\temp\Db.accdb"
    Dim sql As String
    Dim db As Database
    Dim rst As Recordset2
    Dim rstImage As Recordset2
    Dim imageField As Field2
    Dim path As String
    Dim lnga As Integer
    Dim lngkey As Long
    path = "c:\temp\table.png"

    'select the row to be attached by image
    sql = "SELECT * FROM table2  WHERE ID =  1"
    Set db = DBEngine.Workspaces(0).OpenDatabase(dbname)
    Set rst = db.OpenRecordset(sql)

    Set imageField = rst!Blob  ' Blob is the field name to store attachment
    Set rstImage = imageField.Value
     rst.Edit
    rstImage.AddNew
    On Error Resume Next
    rstImage!FileData.LoadFromFile path
    If Err <> 0 Then
    MsgBox "Error: " + Err.Description, vbInformation, path
    Exit Sub
    End If
    rstImage.Update
    rst.Update

   Set rst = Nothing
   Set db = Nothing
End Sub
