how to update StatusBar?

[Anonymous]

Howdy! I've managed to build a status bar and I can assign it a value when the application starts, but how can I update it while the application is running? In the CMainFrame::OnCreate I can use m_wndStatusBar.GetStatusBarCtrl() to get the address of the StatusBarCtrl, but how could I get it outside CMainFrame class? -Marko H. :confused:

If you want to set the text in leftmost part of status bar, use CFrameWnd::SetMessageText. For other statusbar panes, use normal ON_UPDATE_CMD_UI mechanism. Tomasz Sowinski -- http://www.shooltz.com

uh-oh... I'm a newbie. What I meant is that from a CDocument class function I want to change the status bar first pane text. How can I write status bar from there? I don't have inside CDOcument class the address of the CFrameWnd class object to use CFrameWnd::SetMessageText.

Use this:

static_cast<CFrameWnd *>(AfxGetMainWnd())->SetMessageText("I'm on status bar now");

Keep in mind that this changes the status bar text until next idle update UI cycle is executed. Do you want to change this text permantently? Tomasz Sowinski -- http://www.shooltz.com

Still baffled... I added the code, no effect. I want to show on the status bar when the data was last time saved successfully. Now it just shows the date & time once, when CFrameWnd is created. CDocument object function should be able to update the information permanently.

void CMainFrame::GetMessageString(UINT nID, CString & rMessage) const
{
if (AFX_IDS_IDLEMESSAGE == nID)
{
rMessage = "I'm on status bar";
return;
}

CMDIFrameWnd::GetMessageString(nID, rMessage);
}

have a look at this article http://www.codeproject.com/script/Submit/ViewHTML.asp?guid=%2Fuseritems%2Fstatusbar%2Easp%2D2%2F20%2F2002 HTH.

I take that you're able to create a status bar in MainFrame (including setting pane # and size). Once outside of MainFrame, youneed to get a pointer to it to modify the status bar remotely. #include "MainFrm.h"//or equivalent .h . . . CMainFrame* pFrame = (CMainFrame*)AfxGetApp()->m_pMainWnd;//pointer to mainframe object . . . pFrame->UpdateStatus(1, "1st panel message...");//and so on ralf.riedel@usm.edu

Aaaahh... I'm a moron (but not moron enough not to write under anonymous ;-) 1st: status bar has this default feature to show "ready" or tooltip on it. I forgot that. I had made my own simple status bar, and I mixed on the way SetMessageText and SetPaneText. 2nd: I couldn't get my hands on the CMainFrame object. Thanks to the replies, now I could! 3rd: (back to the being stupid) When I was instructed to use pFrame->UpdateStatus(1, "1st panel message...") I was just baffled ".. but there is no UpdateStatus in CFrameWnd class..." :-) Ok, here is how it works now, in case this helps someone else. I am NOT updating the default message text on the status bar, I have created my own pane with a text: in MainFrm.h must be lines public: void UpdateStatusBar(CString sMessage = ""); - - - - - - int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct) { if (CFrameWnd::OnCreate(lpCreateStruct) == -1) return -1; if (!m_wndStatusBar.Create(this) || !m_wndStatusBar.SetIndicators(indicators, sizeof(indicators)/sizeof(UINT))) { TRACE0("Failed to create status bar\n"); return -1; // fail to create } UpdateStatusBar(); return 0; } - - - - - - void CMainFrame::UpdateStatusBar(CString sMessage) { CWinApp* pApp = AfxGetApp(); // the values are read from the registry CString strValue, strValue2; strValue = pApp->GetProfileString("Latest update","Date"); strValue2 = pApp->GetProfileString("Latest update","State"); if (strValue.IsEmpty()) { m_sPaneText = "Data saved: n/a"; } else { m_sPaneText.Format("Data saved: %s, %s", strValue, strValue2); } CStatusBarCtrl &stCtrl = m_wndStatusBar.GetStatusBarCtrl(); // Let's keep it simple... stCtrl.SetSimple(); // in case you want send a different message to the status bar // m_sPaneText is a member of CMainFrame if (sMessage.IsEmpty()) stCtrl.SetText(m_sPaneText,255,0); else stCtrl.SetText(sMessage,255,0); } - - - - - - ...and then at the same in another class... In AppDoc.cpp must be line #include "MainFrm.h" - - - - - - void CAppDoc::SaveDataToServer() { // blah blah blah... save data and other dull jobs... // in my case write to registry. The values are read in // UpdateStatusBar later on and displayed. // update the status bar from CDocument class object CMainFrame* pFrame = (CMainFrame*)AfxGetApp()->m_pMainWnd;//pointer to mainframe object

The link is a dead end...? Or is it just my Netscape Navigator 4.75?

Use ((CFrameWnd*) AfxGetMainWnd())->SetMessageText("...");
