refresh the screen

[ceodav]

Hi,

In my application i have several CEdit to display data. By clicking a button the program updates
all the data inside the CEdit but the values doesn't refresh at all!

The interesting thing is that if switch to another apllication with alt+tab and then i go back to my program all
the data displaying the right value...beside they were refreshed.

Looking with Spy i observed that the message WM_ACTIVATE and WM_CTLCOLORSTATIC were send by the system...
So, how can i send a message to completely redraw the screen at my will?


i hope to be clear...

thanks in advance
Davide

You can use InvalidateRect()

the syntax is:

InvalidateRect(hwnd, NULL, TRUE);

That code will refresh the entire area of hwnd. Or you can specify a certain part of the screen to refresh by sending a RECT structure as the second parameter.

Have you tried using
UpdateData(FALSE);
it might help.

ok i will try with invalidateRect...now a stupid question...

how to get the hwnd of a dialog in MFC?

I think Berras is more on the right track; it has to be something like that. You're probably doing things not the MFC way.

I didn't reply to Berras because UpdateData(FALSE) is the first thing i tried...

It doesn't work because i'm handling graphic element...i guess

You may want to explain a bit more detailed what you're doing, or trying to do. Preferably with some code, because it sounds to me you're doing some strange things. Like for instance: what data exactly gets updated when you click that button, a bound variable, the CEdit itself? Things like that are rather important to know.

And what do you mean by "I'm handling a graphic element"? How are you handling a grapic element with a CEdit?

The problem is very unclear and what you're doing is even more unclear.
