Hi
Can anyone tell me how i can set the position of the cursor in an Edit Control
i want to place a space after the user enters a full stop, im using the below, but this just
puts the cursor back to the start, rather than the end
CString csText, csText2;
m_c_sms.GetWindowText( csText );
csText2 = csText.Right(1);
if (csText2 ==".")
{
csText = csText+" ";
m_c_sms.SetWindowTextA(csText);
}

also :

don't use SetWindowTextA() but SetWindowText().
BTW, AFAIK, you can use CEdit::SetSel(end, end);

use m_edit.SetSel(pos, pos, TRUE);

I believe these are in the wrong order.
Why not something simple like:
CDatabase db;
db.ExecuteSQL("DELETE FROM table);

I guess it is to do with Update.
See MSDN help. It say's
Unlike AddNew and Edit, a call to Delete is not followed by a call to Update.

You mean launching an exe, no ? If yes, see the FAQ[^]

I want to use timers do some actions.
I read about
UINT SetTimer(HWND hWnd, UINT nIDEvent, UINT uElapse, TIMERPROC lpTimerFunc );
versus the
CWnd::SetTimer, UINT nIDEvent, UINT uElapse, TIMERPROC lpTimerFunc );
There is a nice document here explaining some facts. However, I still have some questions about who is handling the timers.
I want to create and handle the timers inside a CScrollView (by mapping and overwriting the inherited CWnd::OnTimer(UINT nIDEvent) and not via a TIMERPROC.
However, I am not sure which timer creation function to use and what value will be good for the nIDEvent on them.
i. How do I guarantee that the CScrollView which created the timer is the one that receives the WM_TIMER message (and subsequently process it). Is it possible that the
WM_TIMER expiration message ends up on another queue (I found that this is possible for mouse messages) or only the creating window can get it?
ii. Is the nIDEvent identifier a system unique one or a view unique one? How do I get a sufficiently unique nIDEvent value to make sure that I am processing the right timer?
iii. Is it possible that my CScrollView will receive time outs (i.e. WM_TIMER messages) by other views or even other threads or applications and under which conditions? If yes what should I do with those timers?
iv. Any idea why SetTimer may fail? Is this due to a system limit on running timers or due to a non unique nIDEvent? How can I know?

i. If you do "this->SetTimer(100, 2000, NULL)" inside your CScrollView class it will use the handle for your view.
ii. It is unique to your view. How many timers are you planning on using? If just one declare a constant.
iii. Yes if some sends the WM_TIMER message to that view. Really shouldn't happen though.
iv. How do you know it's failing?

Thanks a lot. It clarifies a lot of things.
Thus, I can be sure that my view and only this will handle the timers. My plans are to use one timer primarely but there are some rare cases that I may have two running similtaneously. However, if their ids are view unique ones I can use constants to guarantee uniquness and I am assuming that noone sends to my view a WM_TIMER message (according to what you said it sounds a reasonable assumption. Note that the thread will have more than one CScroll views of the same or different type).
According to my reading SetTimer indicates failure if it returns zero. Thus, I know that it is failed to create a timer. But it seems to me that this is due to system resources limits thus, nothing that I can do about it.
Well, was quite helpfull clarifying these points, hope now that they will work like these.
Dimitris...
