Thanks for your reply
I've looked into this and you can also run direct from the command line as follows:
"filepath where SProStaad.exe is saved in quotation marks" /s staadfilepath.std
for example, open Notepad and save these lines as a *.bat file (saving in Notepad under "all files" as save type). The /s is a switch to run files sequentially.
"C:\Program Files\SProV8i\STAAD\SProStaad\SProStaad.exe" /s C:\MyStaadFiles\Model_1.std
"C:\Program Files\SProV8i\STAAD\SProStaad\SProStaad.exe" /s C:\MyStaadFiles\Model_2.std
"C:\Program Files\SProV8i\STAAD\SProStaad\SProStaad.exe" /s C:\MyStaadFiles\Model_3.std
"C:\Program Files\SProV8i\STAAD\SProStaad\SProStaad.exe" /s C:\MyStaadFiles\Model_4.std
etc etc.........
Double click your batch file and it will run the staad files sequentially. This is a vanilla way of running multiple files without having to open an application with VB.
Have a good day
