The easy way is to create a macro that will run your program that won't end until the program ends.

Another way is to make use of the $objecthandle$ parameter which, I pretty sure, will do what you need.

Hi Django,

Thanks for your reply.

I have tried both methods.

1. When I create a macro that calls the .exe, Sage desktop still allow to exit without prompting the opened window. This is my function call..is it correct? 
Do I need to add anything else to get it working as per a normal macro?

Sub MainSub()

Call Shell( myfiilepath, vbNormalFocus)

End Sub

2. I have tried the $objecthandle$ parameter as per Stephen Smith's blog
(https://smist08.wordpress.com/?s=objecthandle) but could not pass CreateSession line which throws a "Session is not initialized error"

strObjectHandle = Command$

lACCPACSignonID = 0 
Set ACCPACSessionMgr = New ACCPACSessionMgr
With ACCPACSessionMgr
.AppID = "XY"
.AppVersion = "64A"
.ProgramName = "XY1000"
.ServerName = "" 
.CreateSession strObjectHandle, lACCPACSignonID, ACCPACSession 
End With

I passed $objecthandle$ in my command line argument.

Am I missing anything?

Thank you for your kind attention and assistance.

Have you initialised the ACCPACSession  object?

I normally don't use that Session Manager object and use the AccpacSession object directly.

Something like:

       static AccpacCOMAPI.AccpacSession _session;

        private static void OpenSession(string objHandler)
        {
            _session = new AccpacCOMAPI.AccpacSession();
            _session.Init(objHandler, "XY", "XY1000", "66A");

            if (string.IsNullOrWhiteSpace(objHandler))
            {
                _session.Open("ADMIN", "ADMIN", "SAMINC", DateTime.Now, 0, "");
            }
        }

Hi, yes I have used an ACCPACSession.

Thanks. 

For anyone interested, I manage to do this by Django's answer to create a macro that will run the program, but the macro has to run some other functions in addition to calling the program.

Thanks!
