I have an SDI style (no doc/view) MFC application that has several windows. These the content of these windows take a while to initialise and the net result is that from double clicking the icon to the application apearing takes a long time and makes it apear that it has not been started.
I would like the main ui of this application to appear asap and then initialise the processes that take time to get going.
Anyone have suggestions how I might be able to achieve this?

You can start the task once the dialog is showing. You can use a thread that would keep on downloading and updating the controls and the data that you need to show in your application, also you can show a progress bar somewhere on the screen of your application that some work is in progress and the user needs to wait until he can work on the application.
Somethings seem HARD to do, until we know how to do them.

My app isn't dialog based! But I assume the technique would be the same for a dialog app and Windowed app. Would I start off my thread from OnShowWindow or OnActivate? (with traps to ensure it dosent get fired more than once)

So what are you having the application do?

I havent got to the point of working out what is taking up the time but I thint it might have somting to do with the 2 http (aspx) server (one used by the application only and the other for external access only) and displaying of a video file.
These are things I want to delay the start up/initialization of.

So don't start these things until after the application has fully shown itself.

This is exactly what I want to do hence the original post...
When do I know when the application has fully shown itself?

That's hard to say since you've removed the doc/view support from it. Do you still have a "main" frame? Has anything replaced the view?

I do still have a Main frame. The main frame contains a CChildView and this is where all the other visible elements are contained. CChildView inherits CWnd.

My first guess would be to post a message from CChildView::OnCreate(). In the handler for that message, start your other processing. This is likely to not work, however, if the "other processing" ties up the main thread enough such that it cannot finish rendering the UI.

After adding various handlers (WM_ACTIVATE & WM_SHOWWINDOW) which just produce trace statments so I can see the order of events. I have come to the conclussion there there are two ways of tackling this... (could be more!)
1) Start a thread in response to a WM_ACTIVATE (with mechanizm to prevent it from being run a 2nd time).
2) Finish off the initialization from the InitInstance() function in the CWinApp derived class.
Do these seem good options?
Out of curiosity how could it be done if was using doc/view?

Probably in the CView::OnUpdate() method.

First register a window message for your application using RegisterWindowMessage and provide a handler for this message, then broadcast this message.
This message will only be processed by your application since the Message id will be unique for your application.

i'm not sure at all the OP wants to send a own defined message.
it seems more that he is trying to send an already defined message to some windows the OP don't own at all

HWND_BROADCAST is one option, but this sends the message to all top level windows.

Another solution is to create another message( a unique message so that only your application can process this mesasge ) and send that message to the window you got through FindWindowEx. If the window responds, u can came in to conclusion that u have got the handle you want, if not find the next window with the same name using FindWindowEx

Well, wasn't that the point...? E.g. :aaaan wrote: i want to send a message to multiple windows,those window have same caption name
It sounds to me like you want to send messages to windows with the same title, but you cannot use ::FindWindow() because you find windows with the same title, which ...errhh... are the ones you want to send the message to...
I must have gotten you wrong. Can you rephrase it?
What message do you want to send? Is it your own user-defined or an ordinary windows message such as WM_CLOSE?
What is the criteria that makes a certain window a candidate for receiving such message?
What have you done so far and why do you think it's not working?

But do those same-titled windows belong to the same class?
