Re: update status in main frame window
1. WM_SETSTATUS is an example of a custom message. You will have to define
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 text.
You tell the main frame which menu to disable, and it has to keep track of
this information and when the OnUpdateUI handler of the menu item is called
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 CMainFrame
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.
Regards,
Kenji
