popup dialogs in mfc activeX

I tried using PreModalDialog() and it didn't help.

Let me attempt to explaining the scenario better.
I am writing an ActiveX control. Class A is the control class that creates a
socket and listens asynchronously. The message handler function for this
Socket is a member function of Dialog A.

So when there is a connection request from a client, the message handler
function is invoked.

I basically want to

1. accept the conection request.
2. read the incoming message.
3. popup a yes/no Dialog B
4. based on yes/no send true/false back to the client and disconnect the
5. Start asynchronous listening again.

I am able to do 1,2,4 and 5. Am not able to do 3.

I am able to popup Dialog B from a member function of the control class
(Class A) if that member function is invoked directly from the webpage
through an interface function.

But when DoModal() on Dialog B is called from this message handler function
(which is a function of Dialog A class), it just doesn't do it.

Please help.

Handling Popup Menu Commands in Parent ?
Hi guys, I have a CWnd-derived child window that has a popup menu (when you right click), I want to handle some (not all) of those menu commands in the parent. I can get the parent to handle them by using GetParent() in TrackPopupMenu() but then the child can't handle any. If it's a big pain I can handle them all in either the child or the parent but maybe it's pretty easy to do ? Thanks. R.

How To: copy dialogs from one project to another ?

Is there a way to send a user message to any of app's active dialogs?
I have an app that receives external HW-driven events, and I need to pass that information along to any of a number of dialogs that may be active when the event occurs (there can only be one active at any given time). I thought some version of PostMessage would work, but I can't get it to work. It does work if the dialog, on initializing, passes back to the app its hWnd, and the app then uses that hWnd in PostMessage. I can use that technique if I need to, but I'm hoping there's a way for an app to post a message to an active dialog without first knowing its hWnd. Sorry if this...
