strange things happen...

Ok. It seems to me that i'm never gonna get rid of some odd errors. Today's is the following:
I have a dialog opened with some buttons on it. When the user presses one of the buttons i want to open a new dialog, something like "advanced settings", the problem is that the second dialog doesn't show up but the controls in it they do. So i'm getting something like this (SEE ATTACHED JPG)
The code is the following, for the first dialog (called ID_NEWDLG) i use:

Code:

---

DialogBox(GetModuleHandle(NULL), MAKEINTRESOURCE(ID_NEWDLG), hwnd, NewDlg);

---

and then i use the following code to open the other dialog:

Code:

---

BOOL CALLBACK NewDlg(
HWND hwnd,
UINT Message,
WPARAM wParam,
LPARAM lParam) {
    switch(Message)
    {
        case WM_INITDIALOG: {
          }
          return TRUE;
        case WM_COMMAND:
            switch(LOWORD(wParam)) {
                case IDOK:
                    EndDialog(hwnd, IDOK);
                break;
                case IDCANCEL:
                    EndDialog(hwnd, IDCANCEL);
                break;
                case IDC_PARAMETERS: {
                    if (IsDlgButtonChecked(hwnd, IDC_RADIOFFWD)) {
                          EndDialog(hwnd, IDOK);
                          DialogBox(GetModuleHandle(NULL), MAKEINTRESOURCE(ID_FFWDPARAMDLG), hwnd, FFwdParamDlg);
                    }
                }
                break;
            }
        break;
        default:
            return FALSE;
    }
    return TRUE;
}

i don't know what is wrong with this code.
I will post the resource script just in case:

i'm pretty sure that the error is not in the resource, but anyway...
Any thoughts will be welcome.
thanks

sorry, i forgot to attach the image. Take a look and you'll see what i mean... :)

Hmmm..

Try CreateDialog() instead of DialogBox()

I noticed another thing that the second dialog you are creating has a parent window which you have allready destroyed.

Also Try to set the parent window to NULL

I tried both things and they didn't work either.
I have created a very simple program that is supposed to do this job, ie. to create a second dialog from a first one, but IT DOESN'T WORK. The code is attached. It is a very small piece of code and is not doing any advanced stuff, so i don't understand what is wrong :(
I would appreciate someone taking a look at it.
thank's
