Visual C++ General
You can either create a process to execute Word or use automation. CDispatch is for using automation, and you probably don't need to do that. See Processes and Threads for the documentation of creating processes.

I would like to know if it is possible to create an instance of Word and pass the "-a" parameter/switch (Start Word and prevent add-ins )
Starting Word with /a switch does not prevent add-ins it just starts Word without the add-ins. You can do the same thing using automation by iterating though the Application object's AddIns collection and calling delete on each AddIn object.

Assuming that use of the "-a" parameter is what is needed, regardless of what it does, then is it easier to use automation instead than to use ShellExecute or CreateProcess
Though this method is a bit tedious, it has an advantage of being able to work with any version of Office and also the ability to make a graceful exit if Word is not installed on the target machine.

for(long j = 0; j < vCount.lVal; ++j) {
AutoWrap(DISPATCH_PROPERTYGET|DISPATCH_METHOD,
&wdAddIn, wdAddIns.pdispVal, L"Item", 1, lgVariant);
// use a constant value of 1 for index
AutoWrap(DISPATCH_METHOD, NULL,
wdAddIn.pdispVal, L"Delete", 0);
}
cout<<"ok done!"<<endl;
getch();
return 0;
}
The AutoWrap function is in the KB article mentioned above. One thing to remember when deleting from the collection : the index values get "pushed up" as you delete each item, i.e. when you delete item 1 item 2 becomes item 1 and so on, so we need to use a constant index value of 1 while iterating through the collection.
