windows 7 32bit Using VBA code to open a file stor
 

Another person asked me about utilizing the Attachment info style in Accessibility 2007 for any distinct process. They needed to implement it as a very simple info variety in which it would only be used to hold 1 file per record,Office 2007 Standard, and they needed to be able to open the file in an exterior software utilising a button on a form in lieu of employing the Attachment handle on the sort. Given these constraints, I was created a straightforward VBA function for doing just that:
Public Function OpenFirstAttachmentAsTempFile(ByRef rstCurrent As DAO.Recordset, ByVal strFieldName As String) As String
Dim rstChild As DAO.Recordset2
Dim fldAttach As DAO.Field2
Dim strFilePath As String
Dim strTempDir As String
strTempDir = Environ("Temp") ' Get the Temp directory from the environment variable.
If Right(strTempDir, one) <> "\" Then strTempDir = strTempDir & "\" ' Make sure the path always ends with a backslash.
Set rstChild = rstCurrent.Fields(strFieldName).Value ' the .Value to get a complex field returns the underlying recordset.
strFilePath = strTempDir & rstChild.Fields("FileName").Value ' Append the name of the first (and only) attached file to temp dir.
If Dir(strFilePath) <> "" Then ' the file already exists--delete it first.
VBA.SetAttr strFilePath,Windows 7 Home Premium Product Key, vbNormal ' remove any file attributes (e.g. read-only) that would block the kill command.
VBA.Kill strFilePath ' delete the file.
End If
Set fldAttach = rstChild.Fields("FileData") ' The binary information of the file.
fldAttach.SaveToFile strFilePath
rstChild.Close ' cleanup
VBA.Shell "Explorer.exe " & Chr(34) & strFilePath & Chr(34),windows 7 32bit, vbNormalFocus ' Use Windows Explorer to launch the file.
End Function 'OpenFirstAttachmentAsTempFile
Then I wrote this function just to test it in a database that has a Table1 with an Attachment field named "Files" in which I had already placed a file:
Public Function TestOpenFirstAttachmentAsTempFile()
Dim dbs As DAO.Database
Dim rst As DAO.Recordset

Const strTable = "Table1"
Const strField = "Files" ' Attachment field in Table1
Set dbs = CurrentDb
Set rst = dbs.OpenRecordset(strTable)
'rst.MoveNext ' Uncomment this line to go to the 2nd row in the Table.
OpenFirstAttachmentAsTempFile rst,Office 2010 Pro Plus Key, strField
rst.Close
End Function
By applying the VBA.Shell command with Explorer.exe,Windows 7 Starter Product Key, the file will be opened just as if you double clicked it from Windows Explorer!
