Depending on the amount to data to load that could be time consuming.

Well, one idea is to have two controls, and do exactly what you describe.
Load the data
into the "other" control, then slide the one on the screen off the right
while sliding the
one which is offscreen in from the left. Handle this with a WM_TIMER
message
void CMyClass::OnTimer(UINT nIDEvent)
{
switch(nIDEvent)
{ /* nIDEvent */
case IDT_SLIDE:
{ /* slide */
CRect oldR;
oldWnd->GetWindowRect(&oldR);
ScreenToClient(&old);
oldWnd->SetWindowPos(NULL, oldR.left + SLIDE_AMOUNT,
oldR.top, 0, 0,
SWP_NOZORDER | SWP_NOSIZE);
CRect newR;
newWnd->GetWindowRect(&newR);
ScreenToClient(&new);
int x = min(newR.left + SLIDE_AMOUNT);
newWnd->SetWindowPos(NULL, x, 0, newR.top, 0, 0,
SWP_NOZORDER |
SWP_NOSIZE);
if(x == 0)
KillTimer(IDT_SLIDE);
} /* slide */
break;
... other timers handled here
} /* nIDEvent */
}
void CMyClass::NextWindow(const CString & s)
{
CWhatever * w = newWnd;
newWnd = oldWnd;
oldWnd = w;
CRect newR;
newWnd->GetWindowRect(&newR);
ScreenToClient(&newR);
newWnd->SetWindowPos(NULL, -newR.Width(), newR.top, 0, 0, SWP_NOSIZE |
SWP_NOZORDER);
SetTimer(IDT_SLIDE, SLIDE_RATE_TIMER, NULL);
newWnd->SetWindowText(s);
}
CWhatever is the class of your window: CEdit, CStatic, or, well, whatever
you are using.
I'm writing this off the top of my head, so it may take a bit of
debugging, but you see
the basic idea. Create two windows, one of them the actual size you want,
one of them
little, tiny, tucked into a corner of your dialog. When the dialog starts
up, you set the
CWhatever * newWnd to point to the actual active window, the CWhatever *
oldWnd to point
to the little tiny window, then you resize the little tiny window to be as
big as the
newWnd, but positioned off-screen (but at the same vertical position)
e.g.,
oldWnd = &Wnd2; // the little window
newWnd = &Wnd1; // the window on the screen
CRect r;
Wnd1.GetWindowRect(&r);
ScreenToClient(&r);
oldWnd->SetWindowPos(NULL, - r.Width(), r.top, r.Width(), r.Height(),
SWP_NOZORDER);
This should get you started.

I am using CE 5.0. I need a control in a dialog box that will display
just text data. The challenge, for me, is that when the user pushes a
right or left arrow to load previous or next data, we would like to
scroll the new screen of data from the right or left with the
appearance that it is "pushing" the old data out of view.
Any ideas would be very much appreciated.
Thanks!
