C++ OPENFILENAME Dialog

I have a question about the GetOpenFileName() dialog. What is the flag that I should use to prevent the user from typing a non-existing file and open it? I would like to see a warning message stating that the file does not exist.

According to Microsoft's docs, the OFN_FILEMUSTEXIST flag should display the message, but it doesn't work in my code. What is missing in the code below?

void openfile(){
    ZeroMemory(&opn, sizeof(OPENFILENAME));
    opn.lStructSize       = sizeof(OPENFILENAME);
    opn.hwndOwner         = hWnd;
    opn.lpstrFile         = tz1;
    opn.nMaxFile          = sizeof(tz1);
    opn.lpstrFilter       = "JPG - JPEG File\0*.JPG\0TIF - TIFF File\0*.TIF\0PNG File\0*.PNG\0BMP - Bitmat File\0*.BMP\0";
    opn.nFilterIndex      = 1;
    opn.lpstrFileTitle    = NULL;
    opn.nMaxFileTitle     = 0;
    opn.lpstrInitialDir   = NULL;
    opn.hInstance         = hInstance;
    opn.Flags = OFN_PATHMUSTEXIST | OFN_FILEMUSTEXIST|OFN_NOVALIDATE;
    bfile=GetOpenFileName(&opn);    
}
