API: how can I eliminate dialogues to run my program in batch without interaction

Hello,
I want to get in a batch program the dependencies from an assembly
with the method GetDependencies():
docName = "J:\\Company\\rade\\sld_dev\\myAss.SLDASM"
swApp = win32com.client.Dispatch("SldWorks.Application")
swMod = swApp.OpenDoc(docName, 2)
dependencies = swMod.GetDependencies(1,1)
swApp.CloseDoc(docName)
swApp.ExitApp()
This works fine with assemblies was construct in my current SolidWorks
2005 installation.
But when I open assemblies from an older installation, I get the
dialogue "The following documents will be converted when saved" (in
german: "Die folgenden Dokumente werden beim Speichern konvertiert
werden.") and I must respond to this dialogue.
How can I eliminate this dialogue to run my program in batch without
interaction?
When I want to get the dependencies from an assembly with missing/
nonconforming files I get a dialogue "Internal ID of document does not
match the internal ID saved with the referencing document. Select yes
to except or no to browse for replacement model" and I must also
respond to this dialogue.
How can I eliminate this dialogue to run my program in batch without
interaction?
Thanks for your answer, Thomas
