CodePudding user response:

Can try only in the old display content and new content of the rectangular area InvalidateRect
You can also try using double buffer technology
Remind: the use of any technology, full screen white and full screen black show alternately, sparkles,

CodePudding user response:

Don't use myedit - & gt; SetWindowText (outresult);

Edit. SetSel (1, 1);
Edit. ReplaceSel (pbufs) (char *);

CodePudding user response:

CodePudding user response:

Why can't use

CodePudding user response:

Edit box of double buffer will not quite, can you teach me

CodePudding user response:

myedit - & gt; SetSel (1, 1);//is your pointer

CodePudding user response:

Well, discovered, but as if it's no use, will flash, who would double buffer can teach me?

CodePudding user response:

Don't
The InvalidateRect (NULL, NULL, true);
Have a try

CodePudding user response:

I also met this problem, you direct SetWindowText will flash, can use ReplaceSel and SetSel,
If you want to use double buffer, then you have to rewrite the CEdit this class, one at a time to draw the last visible area of a string of a string,
As for the double buffering is under the temporary memdc drawing first, then a one-off drawing on the screen...

CodePudding user response:

You can also try RichEdit control

CodePudding user response:

Well, found the problem, it seems I have been in the timer timing to refresh

 
GetDlgItem (IDC_Timer1) - & gt; GetClientRect (& amp; The rect); 
HWND HWND=myedit - & gt; GetSafeHwnd (); 
The InvalidateRect (hWnd, & amp; The rect, true); 

Myedit - & gt; SetWindowText (wtime2); 

So that you can only refresh timer

CodePudding user response:

Why InvalidateRect (hWnd, & amp; The rect, true); ?
Myedit - & gt; SetWindowText (wtime2); They will be refresh

CodePudding user response:

Threads do not interface Time Thread
(PVOID pM)Initialization time
The SetTimer (1100, 0, 0);

The code in the OnTimer

CodePudding user response:

Ontimer used, but the timing is not, sometimes also gets stuck, so finally decided to use thread,

CodePudding user response:

The message in the thread
