Hello,

I have an application that will run in background and won't show a window.

I have a dialog, which I use to perform the actions my app needs to do.

I've tested my app with the wizard generated InitInstance() method:

BOOL CMyApp::InitInstance()
{
CWinAppEx::InitInstance();
SetRegistryKey(_T("MyCompany"));

CMyDlg dlg;
m_pMainWnd = &dlg;
INT_PTR nResponse = dlg.DoModal();
if (nResponse == IDOK)
{
// TODO: Place code here to handle when the dialog is
// dismissed with OK
}
else if (nResponse == IDCANCEL)
{
// TODO: Place code here to handle when the dialog is
// dismissed with Cancel
}

return FALSE;
}

Now I need to stop showing the main window, and the code above shows the
dialog modally. How I can do it? Can I show the CDialog derived class object
hidden? I think that would solve the problem.

After the line
m_pMainWnd = &dlg;
I tried
dlg.ShowWindow(SW_HIDE);

But I got ASSERT errors.

Change the dialog to modeless. To do that call Create in the dialog's
constructor. Then your InitInstance should do this:

m_pMainWnd = new CMyDlg();
return TRUE;
