Excel Automation

Zip file(s) with the default Windows zip program (VBA)

Information

Copy the code in a Standard module of your workbook, if you just started with VBA see this page.

Where do I paste the code that I find on the internet

Warning: The code below is not supported by Microsoft.

It is not possible to hide the copy dialog when you copy to a zip folder (this is only working with normal folders as far as I

know). Also there is no possibility to avoid that someone can cancel the CopyHere operation or that your VBA code will be

notified that the operation has been cancelled.

Note: Do not Dim for example FileNameZipas Stringin the code examples. This must be a Variant, if you change this the

code will not work.

If you want to Unzip files see this page on my site.

Unzip file(s) with the default Windows zipprogram (VBA)

Code used by every example macro on this page

Every macro use the sub NewZipand the first example also use both functions.

Sub NewZip(sPath)

'Create empty Zip File

'Changed by keepITcool Dec-12-2005

If Len(Dir(sPath)) > 0 Then Kill sPath

Open sPath For Output As #1

Print #1, Chr$(80) & Chr$(75) & Chr$(5) & Chr$(6) & String(18, 0)

Close #1

End Sub

Function bIsBookOpen(ByRef szBookName As String) As Boolean

' Rob Bovey

On Error Resume Next

bIsBookOpen = Not (Application.Workbooks(szBookName) Is Nothing)

End Function

Function Split97(sStr As Variant, sdelim As String) As Variant

'Tom Ogilvy

Split97 = Evaluate("{""" & _

Application.Substitute(sStr, sdelim, """,""") & """}")

End Function

Examples

There are five examples on this page that you can copy in a normal module of your workbook.
