Excel export chart to wmf or emf?

I am trying to export a chart from Excel to either the wmf or emf format.

The code works if you export to GIF but not with WMF as the filtername.

This works:

Chart.Export FileName:="current_sales.gif", FilterName:="GIF"

But

Chart.Export FileName:="current_sales.wmf", FilterName:="WMF"

fails giving the error:

Run-time error '1004': Application-defined or object-defined error

Powerpoint allows you to export to WMF. And I have "successfully" exported by copying the graph into Powerpoint and having Powerpoint export the image to WMF but there has to be an easier way - I hope.

I wonder if there may be a way of registering the WMF filter for Excel but I am unsure how to do this. Please help! Thanks.

This copy, save method worked for me, i put it into 3 sections (declarations, saves as EMF function, and the select/copy/function call section):

*I found this article detailing how to save to EMF then doctored it a bit to use the an ActiveChart instead of a arbitrary selection.

First off a couple declarations:

Option Explicit

Private Declare Function OpenClipboard _
    Lib "user32" ( _
        ByVal hwnd As Long) _
As Long

Private Declare Function CloseClipboard Lib "user32" () As Long

Private Declare Function GetClipboardData _
    Lib "user32" ( _
        ByVal wFormat As Long) _
As Long

Private Declare Function EmptyClipboard Lib "user32" () As Long

'// CreateMetaFileA DeleteEnhMetaFile
Private Declare Function CopyEnhMetaFileA _
    Lib "gdi32" ( _
        ByVal hENHSrc As Long, _
        ByVal lpszFile As String) _
As Long

Private Declare Function DeleteEnhMetaFile _
    Lib "gdi32" ( _
        ByVal hemf As Long) _
As Long

This is the actual save as emf function (the use of CopyEnhMetaFileA and DeleteEnhMetaFile are explained in the article):

Public Function fnSaveAsEMF(strFileName As String) As Boolean
Const CF_ENHMETAFILE As Long = 14

Dim ReturnValue As Long

    OpenClipboard 0

    ReturnValue = CopyEnhMetaFileA(GetClipboardData(CF_ENHMETAFILE), strFileName)

    EmptyClipboard

    CloseClipboard

    '// Release resources to it eg You can now delete it if required
    '// or write over it. This is a MUST
    DeleteEnhMetaFile ReturnValue

    fnSaveAsEMF = (ReturnValue <> 0)

End Function

Then the select, copy, and function call section:

Sub SaveIt()
Charts.Add
    ActiveChart.ChartArea.Select
    Selection.Copy
    If fnSaveAsEMF("C:\Excel001.emf") Then
        MsgBox "Saved", vbInformation
    Else
        MsgBox "NOT Saved!", vbCritical
    End If

End Sub

Through this forum entry you can find the marvelous Stephen Bullen's Excel Page and download the PastePicture utility which shows how you can export to the WMF format.

It basically copies the chart, pastes it into the clipboard as a picture and saves its content into a WMF file in a few lines of code.
