hi man,

in fact, we uns pointers for many reasons. First, in C++, the existence of the pointers comes from the compatibility with the C, in which references don't exist.
We also use pointers instead of value copies in function calls because it become heavy and "memory hungry" if we transfer some big data structures... for that reason, we also have the const keyword to avoid writing on pointed datas.
The last reason i see wee use pointers for, it is because sometimes, we don't use variable names to refer to datas (tables, vectors, queues...). We so don't have other way to manipulate these addresses that with pointers...

Hi, I have two projects, one client and one server project. I would like to have both projects in one workspace, and when the user starts the application, he can choose to load either the client project or the server project. How do I do this?

THANKS!!

This is a complete answer but it will solve part of it.
What you do is on the workspace window, click on tabview, right click at the top of the treeview and say insert workspace, select the workspace either ther server or the cient depending on which workspace you are inserting to.

Now on the classview you will see 2 workspace, right click on the workspace and select 'Set active project'.
Now run the application , which ever is the active project will be executed.

Hope this solves ur problems.

Intercept PropertySheet tab notification

Can anyone please help? Confused | :confused:

I know that I can modify the style and icons associated with the tabs in a CPropertySheet, but how can I handle tab control notifications. One (among many) of things I want to do is determine when the user has clicked on an active tab and toggle the icon for that tab.
Thanks in advance.

One way i can thinkof is create a class derived from tab control, then
in oninitdialog of the propertysheet get the pointer of the tabcontrol and subclass it, this way you will recevie all the notifications of the tabcontrol to your tabcontrol class.

Thanks Mr.Prakash.
Just to clarify.
1. Derive a class object from CTabCtrl (CMyTabCtrl) with message handlers for tab messages like (IsChanging, Click etc).
2. Include the new header in my CMyPropertySheet.
3. Maintain a protected member (CMyTabCtrl m_oTabs) in CMyPropertySheet
4. In CMyPropertySheet::OnInitDialog do m_oTabs = GetTabControl();
Is there anything else I need to do in order to subclass the tabcontrol?
Thanks again.

and
no 4th is wroung.

4. Get the tabcontrol pointer using GetTabControl()
CTabCtrl *pTabCtrl = GetTabControl();

5. subclass the window.
m_oTabs.SubclassWindow(pTabCtrl->m_hWnd);

This will direct all the messages and notifications of the tab control to your tabcontrol.

Outlook problem - 'Saved' property for appointment item

YaronNir25-Feb-04 23:34

25-Feb-04 23:34

Hi all,

I've created my own form. when it opens, and i am not changing anything, and try to close it, i get the message 'do you want to save your changes'....
i've look via outlook spy at the appointment item properties and saw a 'read only' property called 'Saved' which has the value false.

my guess is that is what causing the form to be closed with the saved question first....

my question is how to start the form with the saved as true? (as i mentioned before it is a read only property)
can this be done using MAPI?

thanks in advanced

Yaron

The question was posted (and encoded) in Traditional Chinese. In English, it can be translated as "How to capture the 'Enter key' hit on an Edit Control"

My suggested solution would be to use PreTransMessage() and do something like the following;

BOOL CMyDlg::PreTranslateMessage(MSG *pMsg)
{
	int ctrlID;

	if (pMsg->message == WM_KEYDOWN)
		if (pMsg->wParam == VK_RETURN)
		{
			ctrlID = (GetFocus())->GetDlgCtrlID();

			if (ctrlID == IDC_MYEDIT)
				// do your stuff here

			return true;
		}

	return CDialog::PreTranslateMessage(pMsg);
}

Hope it helps

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
