I would like to have my program look into a directory and return back all the filenames within it. Does anyone know what the class and function call does this?

Thanks!

FindNextFile API function or CFindFile MFC class.

Like it or not, I'm right.

How does the .clw file look like. You can edit it and restore it.Otherwise delete the .clw file and press Ctrl+W in the resource editor screen. This would restore the clw file

Enable3dControls failing assert

First off, I am using VS.NET. I have a dialog application which will compile fine in debug mode, however it does not compile in release mode. When I compile it in release mode I get the following error:

D:\Program Files\Microsoft Visual Studio .NET\Vc7\atlmfc\include\afxwin2.inl(1034): error C2039: 'Enable3dControls' : is not a member of 'CWinApp'

I know that in VS7 the Enable3dControls function has been deprecated and doesn't need to be called.. and it isn't anywhere in my dialog application either. For some reason it's not passing the assert on line 1034.

Has anybody seen this before? Any ideas on what I need to include, define, etc. to make it go away?

Thanks in advance,

In my CString variable, a "&" character can be in it. When it is displayed in a messagebox or in a dialog in converts the "&" to underline the next character. Is there a way to turn this feature off so it displays the "&" as an "&"???

Select the "No prefix" style of the offending control static text control. This will cause ampersands to be displayed normally, instead of underscoring the following character.

modeless dialog and memory leak

16-May-02 9:22

I want to display a dialog as a modeless one. And my code is:

CMyDialog *pDlg;
pDlg = new CMyDialog();
if ( pDlg != NULL )
    if ( pDlg->Create(IDD_DLG_MY, this) )
        pDlg->ShowWindow(SW_SHOW);

but where should I delete the pDlg? If I don't delete it, it causes memory leak.

Thank you very much!

make pDlg a member variable of the class that creates it. then delete pDlg in the destructor for the owning class.

Modeless dialogs are usually deleted in the OnNcDestroy routine. Just add that message handler and do a "delete this".

But being this here's CodeProject, the most powerful forums in the world and would blow your head clean off, you've got to ask yourself one question, Do I feel lucky? Well do ya punk?

Hi Tim, I add the following code to myView:
in myView.h:
afx_msg void OnNcDestroy();
in myView.cpp:
ON_COMMAND(WM_NCDESTROY, OnNcDestroy)

void CMyView::OnNcDestroy()
{
delete this;
CScrollView::OnNcDestroy();
}

But it is not called. And the memory leak is till there. How should I did it?

Do you need to use a pointer?

CMyDialog Dlg;
if (Dlg.Create(IDD_DLG_MY, this))
   Dlg.ShowWindow(SW_SHOW);

Like it or not, I'm right.

How do i catch events from a ListView control?

Click, ItemSelect, etc.?

I've noticed that when you click it or do some action on it, i don't get a WM_COMMAND message and i don't get the name of the control in the wParam parameter.

Thanks

Select the control in ClassWizard and choose a notify message handler for the appropriate notification.

Still having problems double buffering a CListView MDI

Hello,
Here is some code.. I am trying to double buffer my CListView MDI app.. I am getting all kinds of really weird drawing.. Alot of this code is from a CListCtrl double buffer.. I am trying to use it.. Anyone want to see if they can find some problems.. Thanks!!!

// This is my OnPaint()
CRect  rc;
	GetParent()->GetClientRect(&rc);

	if (rc.Size() == CSize(0,0))
		return;

	CPaintDC dc(this);
	CDC     MemoryDC;
	CBitmap Bitmap;
	CBrush  Brush;

	CRect rcWnd;
	GetWindowRect(&rcWnd);
	int rcWndW = rcWnd.Width(), rcWndH = rcWnd.Height();

	// Paint to a compatible DC
	MemoryDC.CreateCompatibleDC(&dc);
	Bitmap.CreateCompatibleBitmap(&dc, rcWndW, rcWndH);
	CBitmap *pOldBitmap = MemoryDC.SelectObject(&Bitmap);
   
	// Fill background (does what WM_ERASEBKGND would do)
	Brush.CreateSolidBrush(RGB(255,255,255));//GetBkColor());
	MemoryDC.FillRect(&CRect(0,0, rcWndW,rcWndH), &Brush);

	// Hook the header control so that paint gets redirected
	// to the memory dc
	CWMPaintHook  hookHeaderCtrl(GetListCtrl().GetHeaderCtrl()->GetSafeHwnd(), MemoryDC);

	// Do client and children areas first otherwise system
	// scrollbars don't draw correctly.
	Print(&MemoryDC, PRF_CLIENT|PRF_CHILDREN);
	Print(&MemoryDC, PRF_NONCLIENT);

	// Offset the MemoryDC drawing rectangle by rcBounds 
	CRect rcDraw = rc - rc.TopLeft();

	// Dump bits to real device context.
	dc.BitBlt(rc.left,rc.top, rc.Width(),rc.Height(), &MemoryDC, rcDraw.left,rcDraw.top, SRCCOPY);

	MemoryDC.SelectObject(pOldBitmap);

If you need more code, like from my .h let me know and I'll post it.

Thanks,

Rob
