ACC2000: How to Load OLE Objects from a Folder into a Table

View products that this article applies to.

This article was previously published under Q198466

Moderate: Requires basic macro, coding, and interoperability skills.

SUMMARY

This article shows you how to automatically append all files with a particular extension from a specified folder on the hard disk to a table. This routine is good for loading OLE objects, such as .gif, .jpg, .doc, .xls, or .bmp files that are associated with an OLE Server, into a Microsoft Access database.

NOTE: To associate a graphic file with an OLE Server, open it with an OLE Server package, such as Microsoft Imager or Microsoft Paint, and save the file.

Method to Import OLE Object Files

Create the following new table in Design view. Save it as tblLoadOLE:

   Table: tblLoadOLE
   ------------------------
   Field Name: OLEID
      Data Type: AutoNumber
   Field Name: OLEPath
      Data Type: Text
      Field Size: 255
   Field Name: OLEFile
      Data Type: OLE Object

   Table Properties: tblLoadOLE
   ----------------------------
   PrimaryKey: OLEID

Use the AutoForm: Columnar Wizard to create a new form based on the tblLoadOLE table. Save it as frmLoadOLE.
Open the frmLoadOLE form in Design view.

Create the following three unbound text box controls in the form header section of the form:

   Form: frmLoadOLE
   ------------------------
   Text Box:
      Name: SearchFolder
   Text Box:
      Name: SearchExtension
   Text Box:
      Name: OLEClass

Create the following command button on the form:

   Command Button
   --------------
   Name: cmdLoadOLE
   Caption: Load Files

Type the following event procedure in the OnClick property of the cmdLoadOLE button:

Private Sub cmdLoadOLE_Click()

   Dim MyFolder As String
   Dim MyExt As String
   Dim MyPath As String
   Dim MyFile As String
   Dim strCriteria As String

   MyFolder = Me!SearchFolder
   ' Get the search path.
   MyPath = MyFolder & "\" & "*." & [SearchExtension]
   ' Get the first file in the path containing the file extension.
   MyFile = Dir(MyPath, vbNormal)
   Do While Len(MyFile) <> 0
      [OLEPath] = MyFolder & "\" & MyFile
      [OLEFile].Class = [OLEClass]
      [OLEFile].OLETypeAllowed = acOLEEmbedded
      [OLEFile].SourceDoc = [OLEPath]
      [OLEFile].Action = acOLECreateEmbed
      ' Check for next OLE file in the folder.
      MyFile = Dir
      ' Go to new record on form.
      DoCmd.RunCommand acCmdRecordsGoToNew
   Loop

End Sub

Save the frmLoadOLE form and open it in Form view.
In the SearchFolder text box, type the full path name of the folder that you want to search.
In the SearchExtension text box, type the file extension that you want to load, such as bmp, jpg, doc, xls, tif, or gif. Do not type a period as part of the extension. For example, do not type .bmp.
Type the Class name for the type of file that you are loading, such as Paint.Picture for .bmp files.

NOTE: To determine the Class name of an OLE object, see the documentation for the application supplying the object.
Click the Load Files button. Note that All files that match the SearchFolder and SearchExtension that you entered are added to the tblLoadOLE table.
