Hi,

I just recently used Marcio Ritter's tutorial on game programming to make a directX app. Sadly, it's not working (the OnIdle() function is causing problems). I asked Marcio about it, but I believe he is pretty busy, and was hoping that maybe some could glance at the code. It's very basic, and I'm sure it's something very simple that's causing it to crash. Oh well, if you would like to look at it, my e-mail is nreveles@austin.rr.com

Thanks for your time,

If you think OnIdle() crashes just post some source code.

I didn't think it would be much help by itself, but here it is anyway Smile | :)

        if( hRet == DD_OK )

Have you stepped through it with a debugger?

Where does it crash? Does it crash the first time through the loop? At the very least I would add some trace statements so that you can tell what happens each time through the loop.

With out any more information I dont really know how to help you.

Ok, sorry. I have not actually ran the debug because my app runs full screen and that seems to be causing debug problems. I also do not understand how to use trace properly Blush | :O

I have, however, determined that the following statement is causing it to crash:

g_Brick.Draw(g_pDDSBack, 10, 10, 2, 2, 10, 10);
</code>

Perhaps you could quickly explane how to use trace?

Sorry about the inadaquate information,

Hello, please excuse my bad english....

I want to create a resizeable rect. (I know I can do this with WS_THICKFRAME, but the Border is to thick...)

So I override the WM_NCCALCSIZE function and deflate my window about 5 pixel. So I had a new Non-Client area. When I receive for example a WM_NCMOUSEMOVE message the nHitTest-Paramter is HT_BORDER and not for example HT_LEFT (when I move from the left side). Why send the OnHitTest method not HT_LEFT? Is there a chance to calc the correct Message automaticly (as WS_THICKFRAME)

Creating a FrameWindow without View or doc

I did this in the InitInstance

m_pMainWnd = new CMainFrame;
m_pMainWnd->LoadFrame(IDR_MAINFRAME);
m_pMainWnd->ShowWindow(SW_SHOW);
m_pMainWnd->UpdateWindow();

The problem is that my toolbar insists on being in the child area. ie, it is inside the client edge of the framewindow.

What is wrong?

CMainFrame::OnCreate looks like this.

if (CFrameWnd::OnCreate(lpCreateStruct) == -1)
    return -1;

if (!m_toolbar.CreateEx(this, TBSTYLE_FLAT, WS_CHILD | WS_VISIBLE | CBRS_TOP
    | CBRS_GRIPPER | CBRS_TOOLTIPS | CBRS_FLYBY | CBRS_SIZE_DYNAMIC) ||
    !m_toolbar.LoadToolBar(IDR_MAINFRAME))
{
    return -1;
}


m_toolbar.EnableDocking(CBRS_ALIGN_ANY);
EnableDocking(CBRS_ALIGN_ANY);
DockControlBar(&m_toolbar);


return 0;

problem solved. it needed a view also - otherwise, RecalcLayout does not see the controlbars.

I can make my dialog to become a full screen dialog by using following putting code inside the OnInitDialog()

SetWindowPos(&wndTopMost,0,0::GetSystemMetrics(SMCXSCREEN),::GetSystemMetrics(SM_CYSCREEN),SWP_SHOWWINDOW);<br />

Only dialog get full screen but all the items, listctrl, combo box,etc.. on the dialog still the same size.. how can i make a full screen dialog and resizing all the item on that dialog as dialog get larger.

Thanks

GetParent when modeless

john john mackey14-Nov-02 7:40

14-Nov-02 7:40

I have a modeless dialog that pops up a MODAL dialog. What I want to do is position that MODAL child relative to the "parent" modeless dialog - offset upper-left corner by +50.

What I can't do is get a pointer to the modeless (parent) dialog. My code just references the governing MainFrame window. Here is what I'm trying:

BOOL CPopUpDlg::OnInitDialog()
{
CDialog::OnInitDialog();

CRect pRect;
CWnd *pParentWnd;

pParentWnd = GetParent(); // tried GetParentOwner() too
pParentWnd->GetWindowRect(&pRect);

MoveWindow(pRect.left + 50, pRect.top + 50, 400, 400, NULL);
return (TRUE);
}

Can you help/explain how I reference the correct modeless parent I want?

Thanks.
John

GetParent() should return a pointer to the modeless dialog, if that is in fact who created CPopUpDlg.

Ok, here is what I have:

A modeless CPropertySheet derived dialog with a CButton that pops up a modal dialog. The modal dialog I use to collect a couple fields of data SPECIFIC to the parent modeless Sheet.

What happens now is when I pop up the modal dialog, the positioning is relative to the Main Frame.

I want the modal dialog to be placed right over the modeless Sheet (dialog).

Also, I can see that my method of placing the modal dialog is relative to the Main Frame because when I move the Main Frame around, the modal dialog is offset +50 from the Main Frame.

Thanks for help (in advance)

Try using SetWindowPos() if MoveWindow() doesn't work. (Cheesy answer, I know).
