Hello NG,

when I start my MDI App, 2 DocTemplates are opened with
OpenDocumentFile(NULL).
Each window has special and time costing function calls in OnInitialUpdate.
Now I want the first window to be ready initialized and shown, and after
that open the second window. Sleep not work between both OpenDocumentFile.
So I tried the following:

FileNewWindow1();
if (pMainFrame->MDIGetActive())
(pMainFrame->MDIGetActive())->MDIMaximize();
pMainFrame->UpdateWindow();

int ikum=0;
while (::g_pWindow1==NULL && ikum<15)
{
Sleep(500);
ikum++;
}
if (g_pWindow1)
{
ikum=0;
while (g_pWindow1->m_bInOnInitialUpdate && ikum<15)
{
Sleep(500);
ikum++;
}
}
}
pMainFrame->UpdateWindow();
FileNewWindow2();

But this does not help me. The window1 is not shown totally, but the window2
already opens.

How can I manage to open the first window, let it show totally, wait e.g. 5
seconds, and then open the second window?

Thanks for help,
Guido

I don't think the framework will allow you to do that, but you could open
the second window as hidden (SW_HIDE) and then send a message to it from the
first when it is done doing whatever initialization it needs to do. Then
the second window can show itself and update controls or whatever.

Generally, the framework does not provide guarantees about initialization sequences.

I'm not even sure what you mean when you say "start 2 doc templates". Generally you will
use them to create views which you attach to a single document.

The use of a global variable scares me. It doesn't make sense to use one.

This makes no sense; all that happens is that the thread sleeps for 500ms, during which it
does NOTHING. This means that it cannot "concurrently" (while sleeping) initialize any
other window, because you've stopped the thread. A Sleep() in the main GUI thread is
ALWAYS a mistake!

A fundamental error repeated inside a loop!

You are confused about what is going on here.

First, you have not actually said what you are trying to accomplish; are you trying to get
two views on one document, or two document-view pairs up?

And the UpdateWindow() is for the main frame; if you want to see the view displayed, you
should attempt an UpdateWIndow in the OnInitialUpdate to see if this changes the picture.

Sleep() will NEVER change ANYTHING; all it does is stop the thread for 500ms, during which
it cannot do ANYTHING, including updating the other window.

In the OnInitialUpdate of the first window, do a SetTimer(IDT_LAUNCH_OTHER_WINDOW, 5000,
NULL). where IDT_LAUNCH_OTHER_WINDOW is some constant not used for any other timer in this
window class, e.g., if it is the only timer, "1" is a good value
#define IDT_LAUNCH_OTHER_WINDOW 1
In the OnTimer handler, when you get this notification, you can PostMessage to the main
fram to launch the other window, using a user-defined message.
