Wait cursor in dialog

[ZM73]

How to displaying the hourglass cursor during some lengthy processing of a command handler implemented in dialog base application.
I've tried the BeginWaitCursor command, but like MSDN explain, the dialog box normally change the cursor to the standard arrow cursor, and leave the cursor in as the standard arrow cursor.

The nicest way is to use CWaitCursor, like this:

void CMyDlg::OnLengthyOperation()
{
CWaitCursor wait; // set wait cursor

....
} // restore cursor (on destruction)

The point is that there is function
OnSetCursor and each time u move mouse it restores old cursor. To prevent that u need:
1st: set wait cursor by
m_hCurrentCursor = AfxGetApp()->LoadStandardCursor(IDC_WAIT));
SetCursor(m_hCurrentCursor);

2nd: Overwrite function OnSetCursor in ur dialog or not dialog based application and put there code:

BOOL CUrViewOrDialog::OnSetCursor(CWnd* pWnd, UINT nHitTest, UINT message)
{
// TODO: Add your message handler code here and/or call default


SetCursor(m_hCurrentCursor);
return TRUE;

//return CScrollView::OnSetCursor(pWnd, nHitTest, message);
}

When u need to set old cursor place next code:
m_hCurrentCursor = AfxGetApp()->LoadStandardCursor(IDC_ARROW);
SetCursor(m_hCurrentCursor);
