| async call to ActiveX is still blocking UI (VIP replies) |
| microsoft.public.dotnet.general |
| Hello, I am using asynchronous delegates to make a call to a COM ActiveX object, but even though the call occurs on a separate thread, my UI is still blocking. If i put the thread to sleep in my delegate call, the application is well behaved (no UI freeze), but the call to the com object causes the UI to lock up. Do I have to manage calls to an ActiveX object differently than using the BeginInvoke... |
