Thanks AIR.

I followed the MSDN documentation
msdn.microsoft.com/en-us/library/a9ys3wsb.aspx

, and I created a handler

BEGIN_MESSAGE_MAP(CMainFrame, CFrameWnd)
        ...
    ON_UPDATE_COMMAND_UI(ID_INDICATOR_TEST, OnUpdatePage)
END_MESSAGE_MAP()

static UINT indicators[] =
{
    ID_SEPARATOR, // status line indicator
    ID_INDICATOR_CONNECTSTATUS,
};

void CMainFrame::OnUpdatePage(CCmdUI *pCmdUI)
{
    pCmdUI->Enable();
    CString strPage;
    strPage.Format(_T("TEST1)"));
    pCmdUI->SetText(strPage);
}

Then in my child dialog, how can I call this handler to replace TEST1
with TEST2 at the status pane ?
in child function, I set
        CMainFrame *pMain = (CMainFrame*) AfxGetMainWnd();
        pMain->OnUpdatePage ...?

Thanks.

Kenji

1. WM_SETSTATUS is an example of a custom message. You will have to defin=

it somewhere. (I typically put them in a file called messages.h)

#define WM_SETSTATUS WM_APP+1

Then you need to put a handler for WM_SETSTATUS in your CMainFrame window
and there do the m_wndStatusBar.SetPaneText

2. You will accomplish this the same way you change the status window tex=

You tell the main frame which menu to disable, and it has to keep track o=

this information and when the OnUpdateUI handler of the menu item is call=

you are able to disable it there. If you have any questions on how the
ON_UPDATE_COMMAND_UI works let me know.

Hi,

1. ok. I used the AfxGetMainWnd()->SendMessage(WM_SETSTATUS,0,pStr);
   but I got:
   error C2065: 'WM_SETSTATUS' : undeclared identifier
   how to declare it ?

2. One more thing is how can I SendMessage to disable certain menu in
main frame window ?

Many thank to your kind help.

Regards.

There are several ways.

From you button handler you can either do this:

CMainFrame *pWnd = (CMainFrame *)AfxGetMainWnd();
ASSERT(pWnd);
pWnd->GetStatusBar().SetPaneText(0,"Test 123");

note that you need to write a method for GetStatusBar in your CMainFram=

class
CStatusBar &GetStatusBar();

Or you can send a message to the main window
AfxGetMainWnd()->SendMessage(WM_SETSTATUS,0,pStr);

Hi Expert,

I'm using SDI application

In Mainfrm.cpp, i have

static UINT indicators[] =
{
ID_SEPARATOR, // status line indicator
ID_INDICATOR_TEST,
};

I added a child dialog with one test button on it.
The child dialog is triggered via menu in main frame windows. the
class of child dialog is CDialog base.

class CChildDlg : public CDialog
{
public:
CChildDlg();
...
}

void CMainApp::OnEditDialog()
{
CChildDlg childDlg;
childDlg.DoModal();

}

void CChildDlg::OnBtnTest()
{
// how can I update the status bar in main frame windows ?
// the following code will trigger exception...!!!
CStatusBar m_wndStatusBar;
m_wndStatusBar.CommandToIndex(ID_INDICATOR_TEST);

m_wndStatusBar.SetPaneText(0, "TEST 123", TRUE);
m_wndStatusBar.UpdateWindow();

}

How can I update the status bar in main frame windows, upon clicking
Test button.

Thanks in advance.

Kenji
