Question

I need to convert old .mdb Access files to the new .accdb format.
What’s the best way to do this in vb.net?

Answer 1

Use Office InterOp to instantiate Application of Access and try to open .mdb, file then save it using SysCmd method.

Honestly, I didn’t tried so far yet but here are some undocumented sysCmd code but there is a simple approach to convert .mdb to .acccdb via ConvertAccessProject method.

app = new  Application()

src ="c:\csnet\file.mdb"
dst= "c:\csnet\file.accdb"

app.ConvertAccessProject(src, dst, AcFileFormat.acFileFormatAccess2007)
app.Quit()
