Icons for attachments added via VBA

[Nick-B]

Hi,

I have a spreadsheet which I have protected to stop people tampering
with it. As a result in order to add attachments to it I have included
a button and some VBA code. Now this all works fine, except the
attachment doesn't pick up the icon of the associated application (eg:
a word doc, etc), any thoughts on this would be appreciated, below is
the code, thanks:

Private Sub cmdInsert_Click()
Dim strFilename As String
Dim varNumber As Variant
Dim strPosition As String

strFilename = Application.GetOpenFilename(, , "Add Attachment")
If strFilename <> "False" Then
varNumber = InputBox("Enter attachment position number
(1 to 10)", "Add Attachement")

If varNumber >= 1 And varNumber <= 10 Then
strPosition = "D" & varNumber + 5
Range(strPosition).Select

ActiveSheet.OLEObjects.Add(Filename:=strFilename,
Link:=False, _
DisplayAsIcon:=True, *IconFileName:=strFilename*,
IconIndex:=0, _
IconLabel:=strFilename.Select End
If
End IfEnd Sub

FYI,
Putting on the macro recorder I pulled up...
-for a Word Document:
IconFileName:=
"C:\WINNT\Installer\{00020409-78E1-11D2-B60F-006097C998E7}\wordicon.exe"
-for a PDF:
IconFileName:=
"C:\WINNT\Installer\{AC76BA86-1033-0000-7760-000000000002}\PDFFile.ico"
-Excel file:
IconFileName:=
"C:\WINNT\Installer\{00020409-78E1-11D2-B60F-006097C998E7}\xlicons.exe"
Seems you need to determine the type of file being attached, find the
appropriate program and insert that value into the IconFileName value.

Thanks Gary, I did some similar tests this afternoon and was coming to
the same conclusion as you. My concern here is that strings like
"{00020409-78E1-11D2-B60F-006097C998E7}" in the path will not be the
same across different machines, which is essential for me.

Looking at this further this evening it looks like you can simply
specify the executable name without any path (eg:"excel.exe" for a
spreadsheet) and get the default icon for it, which avoids having to
specify the installer path. Unfortunately I will still have to have a
switch statement for at least the main types of file.

Thanks again for your help.

Certainly does help, thanks for this.

With this website and http://www.arcatapet.net/vbregget.cfm (note: all
except the "GetIcon" function were taken from this website) I've come
up with the following which I'm going to integrate into my spreadsheet

registry entry).
