I have created an activeX dll which my app calls periodically, all well and good. The problem is that the app sits and waits for the dll to complete it execution before continuing.
What can I do to stop the app from waiting for the dll and just carry on?
Hmmm; although that link shows excellent technical proficiency, I wouldn't recommend using it for production code.
It is better in VB to have some form of messaging system like MSMQ, or bespoke, that allows asynchronous calls.
Incidentally, if you code your interfaces in IDL, you can expose your IUnknown stuff to return immediately after submitting the function stack to the proxy - which essentially allows asynchonous COM calls - you need to know a bit of C to do this, though.
Do you need to have a ActiveX DLL, this is a in-process component!
Why not convert your DLL to a ActiveX EXE, out-of process component. This will release control back to the calling exe.
I have converted my dll to an exe but the operation is still the same.
