I am trying to put progress control on the status bar and am using the code from example Statusbar:
int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
..............
SetupStatusBarProgress();
return 0;
}
void CMainFrame::SetupStatusBarProgress()
{
// Create the edit control and add it to the status bar
if (!m_ProgressCtrl.Create(WS_CHILD|WS_VISIBLE|PBS_SMOOTH,
CRect(0,0,0,0), &m_wndStatusBar, 0))
{
TRACE0( "Failed to create edit control.\n");
return;
}
// add the indicator to the status bar.
CXTPStatusBarPane* pPane = m_wndStatusBar.AddIndicator(ID_INDICATOR_PROG);
// Initialize the pane info and add the control.
int nIndex = m_wndStatusBar.CommandToIndex(ID_INDICATOR_PROG);
ASSERT (nIndex != -1);
pPane->SetCaption(pPane->GetText());
pPane->SetText(_T( ""));
m_wndStatusBar.SetPaneWidth(nIndex, 150);
m_wndStatusBar.SetPaneStyle(nIndex, m_wndStatusBar.GetPaneStyle(nIndex) | SBPS_NOBORDERS);
m_wndStatusBar.AddControl(&m_ProgressCtrl, ID_INDICATOR_PROG, FALSE);
// initialize progress control.
m_ProgressCtrl.SetRange (0, 100);
m_ProgressCtrl.SetPos (0);
m_ProgressCtrl.SetStep (1);
pPane->SetCustomizationVisible(FALSE);
}
then, before the long operation starts I call the following function that in normal circumstances produces marquee-style progress bar...
void CMainFrame::StartMarqueeProgress()
{
m_ProgressCtrl.ShowWindow(SW_SHOW);
// Set the progress control style to PBS_MARQUEE
//
HWND hWnd = m_ProgressCtrl.GetSafeHwnd();
LONG_PTR dwLong = GetWindowLongPtr(hWnd, GWL_STYLE);
LONG_PTR dwNewLong = dwLong | PBS_MARQUEE;
dwLong = SetWindowLongPtr(hWnd, GWL_STYLE, (LONG)dwNewLong);
// set progress control to blue
//
DWORD dwColor;
CBluetoothControllerApp* pApp = (CBluetoothControllerApp*)AfxGetApp();
if (pApp->IsVista())
dwColor = RGB(0,255,0);
else
dwColor = GetSysColor(COLOR_ACTIVECAPTION);
LRESULT lResult = m_ProgressCtrl.SendMessage(PBM_SETBARCOLOR, // message ID
0, // must be 0
dwColor); // normal color
DWORD dwTime;
if ( pApp->IsVista() )
dwTime = 10;
else
dwTime = 30;
lResult = m_ProgressCtrl.SendMessage(
(UINT)PBM_SETMARQUEE, // message ID
(WPARAM)TRUE, // set to marqee
(LPARAM) dwTime); // time in milisec between updates
}
I get no results... not only the marquee is not displayed, but nothing is displayed on the status bar... Anything I am doing wrong here?
