Hi

    In my dialog based application I must create a modeless, invisible
window:

class CDummyDlg :
        public CDialog
{
     // (...)
};

BOOL
CApp::InitInstance()
{
    // (...)
    InitCommonControls();
    this->TBase::InitInstance();

                CDummyDlg * m_dummy_dlg;
                this->m_dummy_dlg = new CDummyDlg();
    this->m_dummy_dlg->Create(IDD);

    this->m_pMainWnd = this->m_dummy_dlg;
    // (...)
}

Unfortunately the CDialog::Create() method somehow changes the
foreground window from, for example: Total Commander or MS Visual
Studio, or any other program, starting my application, into ....
nothingness - after finishing the Create method there is no Foreground
window in the system. I don't want it to happen till I actually show my
window, which happens after I hit the PrintScreen key, and fire an
event.

The IDD resource does not have the visibility flag set to on. Here is
the complete dialog definition from resource file:

IDD DIALOGEX 0, 0, 323, 201
STYLE DS_SYSMODAL | DS_SETFONT | DS_MODALFRAME | DS_SETFOREGROUND |
    DS_FIXEDSYS | WS_CAPTION
EXSTYLE WS_EX_PALETTEWINDOW
CAPTION "SCC"
FONT 8, "MS Shell Dlg", 0, 0, 0x1
BEGIN
END

How can I prevent the Create() method from changing the foreground
window?

Btw - I cannot delay the creation of this window.

Any help would be appreciated.

Thanks in advance
