If you are using MFC, check out the CDatabase and CRecordset classes. You may also want to read up on what a DSN is, although one is not required.

How can I be notifeid if the caret position has changed or not in a RichEdit control?

I'v a dialog based program with a RichEdit control in it and a few buttons to format the text within it. Now what I wanna do is to be notified whenever the caret positon changes through the lines. (and update the sate of some radio buttons accordingly).

Thank you masters!

My thinking...
"Golly, what a dumb question. Just look at the edit control, and see what messages it sends back. Probably EN_UPDATE or such."
"Hmm, OK, it's not that... Lets fire up a normal edit and look".
"Hmm, just CTL_COLOREDIT coming back"

lots of other thoughts, but in the end, I found:

EN_SELCHANGE

The EN_SELCHANGE message notifies a rich edit control's parent window that the current selection has changed. A
rich edit control sends this notification message in the form of a WM_NOTIFY message.

To receive EN_SELCHANGE notifications, specify ENM_SELCHANGE in the mask sent with the EM_SETEVENTMASK message. 

Note, when there is no selection (that is, the caret is displayed) we have, in fact, the empty selection. Thus,
when the caret position changes (for example, clicking a mouse, typing, or pressing an arrow key), an EN_SELCHANGE
message is sent.

I hope that works for you. Just note that you have to turn notifications on.

To clear the text box use SetWindowText("");
MSDN:
As users click tabs or buttons, the tab control (CTabCtrl) sends notification messages[WM_NOTIFY] to its parent window. Handle these messages if you want to do something in response.

You need to google first, if you have "It's urgent please" mentioned in your question.

You can simply map TCN_SELCHANGE[^] and the set/reset the text box using "SetWindowText" API.

Hi all,

I have SDI type application,i have split it in 1 row and 2 columns.

for first column i have use TreeView and for second column i have used FormView.

on click event on TreeView according to tree items, i have replaced a view in second column,here the replace view working fine but the replaced view not got the focus.

focus is remain at first column.

I want if i replace a view for second column and its is replaced succssfully than focus on second column instead of first column.

please tell me how can i do this.

thanks in advance.

You probably have to explicitly SetFocus to the view you want to be active?

Two linked lists intersect sometimes. What does this mean? They have the same value at intersection or?

Set 1: 1, 2, 3, 4
Set 2: 5, 6, 7, 9, 2

If I store these values in two linked lists, does it mean they have to intersect at 2 or does it mean something else.

You are making an assumption that everyone has access to a teacher. I googled and found many articles about how to find the intersection of two linked lists but none which explain why would they intersect and when/why would you want them to intersect. A real life example will help.

I have been programming for quiet a while but I never had to find out if two linked lists intersect. BTW I mostly have been using managed languages.

In set theory, the intersection on two sets is a third set that contains all the elements the first two have in common.

It means it's a coincidence that both lists contain a node having the value 2.

No reason that I can think of. Yes it's possible, but I've never heard of such an implementation. If you are visualizing something like:

class set : public list
{
};

This says that a set is-a list, which it can't be because a set does not do everything that a list does. Perhaps you wanted a has-a construct where the set contains a list.
