Hi

I have an application that uses .NET, but allows it to pass in a window handle, a window title, else it uses the active window as the parent window.  The code works, apart from the fact that using the TAB key tabs through the controls in reverse, and, if I then use Shift+TAB, they go in the opposite order (so they're swapped!
I have the tab order set correctly, and swapping the tab order around makes no difference it seems
I'd like the dialog window to act as any other window, and be able to react to TAB.  Also, the Default button does not work at all.  Pressing ENTER does nothing although the accept button for the dialog form is set
Any ideas would be highly appreciated, and code to go with it would be appreciated even more

Here is the code to show the window

public void DoModalWindow(IntPtr hParent, Form formToShow
     
        IntPtr hWnd = formToShow.Handle
        bool isClosing = false
        IntPtr parenthandle = IntPtr.Zero
        formToShow.Show()
        // Set parent of window..
        if (hParent != IntPtr.Zero
       
           parenthandle = SetWindowLong(hWnd, GWW_HWNDPARENT, hParent)
           EnableWindow(hParent, false)
       
        MSG msg = new MSG(IntPtr.Zero, 0, 0, 0, 0, new POINT(0,0))
        // These are more in the way of a test, I thought maybe adding accelerator keys might make
        // SHIFT, TAB, ENTER work, but it didn't seem to help.  Having said that, I might be calling i
        // all incorrectly
        ACCEL[] accel = new ACCEL[2]
        accel[0] = new ACCEL(0,(char)0,(char)0)
        accel[1] = new ACCEL(VF_SHIFT, (char)16, (char)0)

        while (formToShow != null
       
           if (PeekMessage(ref msg,IntPtr.Zero,0,0,PM_REMOVE)
           
              if (TranslateAccelerator(formToShow.Handle, ref accel, ref msg) != 0
             
                 continue
             
              else if (IsDialogMessage(formToShow.Handle, ref msg)
                 continue
              els
             
                 TranslateMessage(ref msg)
                 DispatchMessage(ref msg)
             
           
           if ((formToShow != null) && (formToShow.DialogResult != DialogResult.None) && (!isClosing)
           {
              // Get whether we authenticated of not, then kill off the window..
              this.authenticated = (formToShow.DialogResult == DialogResult.OK);    
              formToShow.Close()
              formToShow = null
              GC.Collect()
              isClosing = true
           
       
        if (hParent != IntPtr.Zero
       
           EnableWindow(hParent, true)
           // Set parent of window back to original value..
           SetWindowLong(parenthandle, GWW_HWNDPARENT, hParent)
           ShowWindow(hParent, SW_SHOW)
       
     

Thanks for your help in advance
