How to check if ACCDE?

There was a question at MSDN Forums the other day on how to determine if an Access database file was compiled to an ACCDE. I found this question somewhat interesting, because I never had a need to determine whether a database was a true ACCDE file or not.

When I deploy a compiled database, I often rename the file extension to ACCDR to force Access into Runtime Mode. I use the following code to check if the database is running in Runtime Mode and exit the application if it is not.

SysCmd(acSysCmdRuntime)

However, I could not find an equivalent SysCmd constant to check for ACCDE, and I am not sure if there is a property for it as well. So, I came up with the following function, which seems to do the job.

Public Function IsACCDE() As Boolean
On Error GoTo errHandler

Application.VBE.CodePanes(1).Show
IsACCDE = False

errExit:
    Exit Function

errHandler:
    IsACCDE = True
    Resume errExit
    
End Function

I am not sure if it is the best way to perform the ACCDE check, but I just thought I would share it and see if you can tell me if there is a better way. Thank you!
