VBA - Open a file with Shell if the filename contains a blank?

[OldBirdman]

I want to open a file in WordPad from Access. This code works correctly.

Private Sub cmdOpenRTF_Click()
Dim stAppName As String
    stAppName = "C:\Program Files\Windows NT\Accessories\WordPad.exe " & "D:\Convert\Convert.rtf"
    Call Shell(stAppName, vbNormalFocus)
End Sub

However, if the filename (or folder name) contains a blank, I get the non-trappable error "Failed to open document." No message number.
How can I open a file with Shell if the filename contains a blank?

Use the double-quotes format OB.

stAppName = "My silly space filled filename.Blx"
stAppName = "C:\Program Files\Windows NT\Accessories\WordPad.exe """ & stAppName & """"

Why didn't I think of that? So obvious. Thank you:)
