May be you can send a WM_LBUTTONDOWN message to the main window.

Off the top of my head WM_CANCELMODE[^] is the way to go to cancel menus.

Thanks for your answers.
Anyway, I think it doesn't work.
What I need to do also is to 'close' Start Menu when a timer expires in my application, because that application should go to foreground, and Start Menu should disappear.
I tried to send WM_KEYDOWN and WM_LBUTTONDOWN to Windows task bar, but it does not work.
How could I close that Menu??
Thanks.

Sadly, the start menu is only an imitation menu. It has a load of non-menu features, and varies from one operating system and service pack to another.
About the only thing I can think of is to find the window with the current focus, and send a WM_KEYUP / WM_KEYDOWN with VK_ESCAPE as a parameter.

Hi,
I have a thirdy party OCX. There is a sample VB program which uses "On Error" to trap runtime errors when an OCX method is invoked.
I want to build my application using this OCX and VC++. How do I trap runtime errors ? Do I have to use exception handling ?
Thanks

Hello,
I'm using a print preview view to present the preview of a report in my program.
Things seem to be ok, but I don't like the default behavior that the view
will turn to empty when user press an Esc key and want to disable it.
How can I get this?
Thanks
Max

hi all,
as we can insert the text in an rich edit control with
SetWindowText(string) API
but is it possible to insert some character in between the existing string??
i mean if i know the caret position to insert that character and the actual character to insert then can i insert the characterwith this information??
e.g.
if current text in rich edit control is
love is in the air.
and if i want to insert the character after "in" as "in/" so how i can do that??
please let me know if someone know's how to do this!!
Thanks and Regards

Like this:
You can use CString::Replace() to replace the text.
CString m_str;
m_richedit.GetWindowText(m_str);
m_str.Replace ("in","in/");
m_richedit.SetWindowText (m_str);
Somethings seem HARD to do, until we know how to do them.

yes this is one way but in this way we need to call GetWindowText
and then after changing the text we will say SetWindowText
what i want to do is that
if i have a character and the caret position that is going to tell me where
to insert that character then i will do
SetCaretPos(point)
and now programmatically i want to insert that character ata that position
so how i can achieve that??
and thank's for replying

CPoint pt=m_richedit.GetCaretPos ();
int i=m_richedit.CharFromPos (pt);
CHARRANGE chRange;
chRange.cpMin =i;
chRange.cpMax =i;
m_richedit.SetSel (chRange);
m_richedit.ReplaceSel ("/");
I hope this helps and fits your requirement.

yes thank's anshuman
actually i am doing multilevel undo redo
thanks and regards

Another option is to use CRichEditCtrl::SetSel[^] to set the 'carret' position (in fact, the text which is selecetd in the control, if nStartChar is equal to nEndChar, then, you specify a carret position). You can then use CRichEditCtrl::ReplaceSel[^] to replace the text which is selected (ans thus, insert text also).

yes this is a good approach
actually i am doing multilevel undo/redo for richedit ctrl(CRichEditCtrl)
and when i searched on codeproject i didn't got any undo redo code for CRichEditCtrl.
so currently i am making dynamic stack in which i am storing the caret position and the character.in OnChar handler.
and i am thinking that when user will say undo i will pop one frame and will insert that character in the rich edit control at that position.
Is it a good approach??
and is there no other API that will just take the character and caret position o insert the character??
Thanks and regards

CString m_str;
m_richedit.GetWindowText(m_str);
m_str.Insert( Index, "string to be inserted" );
m_richedit.SetWindowText (m_str);

I have to launch from my code some third party program that may result in system restart. In case that the system restart is not performed immediately (for example with <shutdown t="" 30="" s="">), I need my program to terminate and prevent the user from cotinue running my program in the time remaining till shutdown.
Question: How can I detect that <system shutdown=""> was issued?
(I tried to start some process from my code an get the error code informing that the system shutdown is pending, but this solution is buggy, since I do not know which process can i start on user's machine and in case that there is no system shutdown pending it looks ugly - console opens, etc.)
|

All top-level windows receive a WM_QUERYENDSESSION message when a logoff/shutdown/restart is initiated. If no app cancels the action, windows get WM_ENDSESSION to indicate that the system is shutting down.

Thanks,
but the problem is I can not poll in a loop.
I need to run a single query when I got the control back from the T.P. program I'm running from my code.
Any ideas?

You don't poll to get those notifications, they arrive in the message queue like any other messages.
