>>>I have built an in-process DLL to handle changes to values in a view. In my main exe I create the server object, and call the appropriate method - say, MyDLL.changeview. Before I call the method I make sure my exe is on the appropriate view. However, the DLL is returning an error - that the alias can not be found. In the debugger I can see the alias is correctly selected immediately before the server object is created; but once inside the DLL it is no longer accessible. I have built the DLL on a CUSTOM class rather than a SESSION class as I assumed the latter would cause just the sort of problem I am seeing - as the SESSION class maintains it's own datasession. I thought the CUSTOM class would have the same datasession as the main exe.

Also bear in mind that each object has its datasession. Since you instantiate your object in the main it will have datasession=1

That object will not be able to access data in another datasession (form with private datasession) unless you use set datasession to ...

You may have to instantiate an object per datasession
