Opening a file with photoshop automation [resolved]

Update: I am, in fact, a bonehead. Problem solved:

VB Code:

Public Sub OpenPhotoFile_Click()
 
Dim PhotoDoc As IAutoPSDoc
 
 
'Opens Photoshop
Set photoshop = New PhotoshopApplication
'Opens the template
'Opens the first file
Set PhotoDoc = photoshop.Open("C:\whatever\testme.psd")

Hiya folks. I hope you can help me out.

I've started working on a project that requires extensive automation of Photoshop. My company isn't a member of Adobe's little club and so I don't have access to the SDK, and so if this is a completely boneheaded question I apologize in advance.

I run into an issue right off the bat:

VB Code:

Public Sub OpenPhotoFile_Click()
 
Set photoshop = New PhotoshopApplication
PhotoshopApplication.Open ("c:\whatever\testme.psd")
 
End Sub

Also, I have

VB Code:

Public photoshop As PhotoshopApplication

in my declarations.

The problem is that when I run this, while Photoshop starts up and testme.psd does open up, the file closes immediately afterwards -- almost instantaneously. I'm confused, as I certainly haven't told Photoshop to close testme.psd and (obviously) I really need that file to stay open. Can anyone tell me why this is happening, and more importantly how I can stop it?
