To create a modal dialog box, you have
to use the CDialog constructor and
then DoModal()

If you want a modaless dialog box, you
have to call the constructor and then
Create() (and NOT DoModal()).

If you have generated your application
with AppWizard, you simply have to
find DoModal()
-> in C...App::InitInstance
and call Create instead of DoModal()
Don't forget you have to show it as well,

CMyDialog dlg;


You have to use the function
and NOT Show.

I get a runtime error that brings me here:

HWND CDialog::PreModal()
      // cannot call DoModal on a dialog already constructed as modeless
      ASSERT(m_hWnd == NULL);

      // allow OLE servers to disable themselves
      CWinApp* pApp = AfxGetApp();
      if (pApp != NULL)

I think i fixed that now i get:

SecurityDlg.obj : error LNK2001: unresolved external symbol "public: virtual int __thiscall CSecurityDlg::DoModal(void)" (?DoModal@CSecurityDlg@@UAEHXZ)
Debug/Security.exe : fatal error LNK1120: 1 unresolved externals

I could not understand Ur requirement properly. Why U want the dilaogbased apps main dialog to be modeless?. It makes no difference as such if it is modaled one.

But if U want to create the modeless dialog box, here r the steps.
1. using resource editor, create a dialog with id IDD_MYDIALOG.
2. Add the class to it, say CMyDlg.
3. Then say u want to pop it up in x.cpp, then go to x.h and add the follwing include header to it
#include "MyDlg.h"
Then declare a variable as public as
CMyDlg *m_dlg;

4. Then in the constructor of the x.cpp do
    m_dlg = NULL;
5. Then U want to pop up do
    m_dlg = new CMyDlg;
    m_dlg->Create(IDD_MYDIALOG, this);

Thats it.

There is one way. U can have the dummy SDi app, There pop up Ur main dialog as modeless as I mentioned. Then hide the main window of SDI.

Try it out.
A modeless application (dialog based or otherwise) doesn't make sense.

Do you want your app to float over all other applications? Then use SetWindowPos(wndTopMost, ...) or apply the WS_EX_TOPMOST style.
