Hi,

I am developing an application that uses a full screen
kiosk type user interface, and has the capability of
launching a web browser based session (again in full
screen mode).

The problem is that when switching from the 'normal'
interface to the browser interface, I am getting a
noticeable flicker or white flash. Is there any way I can
prevent this?

For the browser interface, I have a CDialog derived class
that wraps the ActiveX web browser control, so
OnInitDialog looks a bit like this:

// Resolution is 1024X768
const int nMaxX = 1024;
const int nMaxY = 768;

// Create the main dialog window
CRect objRect(0, 0, nMaxX, nMaxY);
// IDD_BROWSER_DIALOG is a dialog resource specified to be
0 x 0 pixels so it is hidden initially, m_webBrowser is an
MFC generated ActiveX wrapper for the browser control
m_webBrowser.Create(BROWSER_FORM_NAME, WS_VISIBLE,
objRect, this, IDD_BROWSER_DIALOG, NULL, FALSE);
        
// Navigate the main dialog window to the holding page URL.
m_webBrowser.Navigate(szURL, NULL, NULL, NULL, NULL);

Then I trap a web broswer event OnDocumentComplete to know
when to actually show the web browser dialog, which looks
like this:

SetWindowPos(&CWnd::wndTopMost, 0, 0, nMaxX, nMaxY,
SWP_SHOWWINDOW);

Any help would most appreciated.

Regards,
Rick
