CSocket nave Paint Issue Anilkumar K V24-Apr-06 21:05 Anilkumar K V 24-Apr-06 21:05  Hi I have set a Background image for my ActiveX ( ATL Composite Control) and it has some static text boxes. To make them transparent i did the painting of the static text controls ( in WM_PAINT). I.e after setting the image in OnEraseBkGnd(), i invalidated the static controls whose WM_PAINT is handled. This will TextOut the text above the BG image. But when i put this in web page, it seems that the OnEraseBkGnd() is calling frequently and thus the static control paint everytime, creating flickering of the static controls ( controls blink's). Also when i call SetWindowText() to set new string in static control, I have to call Inavlidate() the whole control to make the new text display correctly. If i just call invalidate of static control, it overwrite the old text. Next painting of the window will solve this!! How to solve these issues? i have used this CP link to set background. Re: Paint Issue KarstenK24-Apr-06 22:55 KarstenK 24-Apr-06 22:55  There is a OnCtlColor Member of CWnd, in which you can set the backmode to transparent. Greeting from Germany Re: Paint Issue Anilkumar K V25-Apr-06 0:31 Anilkumar K V 25-Apr-06 0:31  I did try with WM_CTLCOLORSTATIC, i could change the bgmode & color Not able to make it transparent. I did have to draw using WM_PAINT M_CTLCOLOR is not fired,I think it is due to ATL non MFC anil To speed data access in server sabitasamal24-Apr-06 20:09 sabitasamal 24-Apr-06 20:09  When a client using shared data from remote machine.It is very fast .But with server for same it is taking more time.

When you release a new version, update the version numbers in the DLL's version resource, and update the version numbers in the INF file (packaged inside the CAB) to match. Then on the web page, update the version field in the codebase attribute to match. IE will do the rest. --Mike-- Visual C++ MVP LINKS~! Ericahist | NEW!!

I've tried not responding to the following messages.... then I tried what you'll see below. I thought by handling them I'd be OK... but IM windows (from Gaim for instance) totally kills focus of my program. Thoughts? Thanks! case WM_KILLFOCUS: case WM_QUIT: case WM_CLOSE: case WM_DESTROY: return(DefWindowProc(hWnd, message, wParam, lParam)); Re: protecting your window from IM windows & other popups Michael Dunn24-Apr-06 20:18 Michael Dunn 24-Apr-06 20:18  You can't prevent your window from losing focus to something else. Imagine if two programs did this - they would constantly be fighting over which one is the active window. What is it about your app that makes you want to prevent other windows from being active? --Mike-- Visual C++ MVP LINKS~! Ericahist | NEW!!

However I've seen some applications deal with it, and not yield control. I'm building a simple screensaver which I think shouldn't be interrupted by such trivial things as IM windows. You still hear the noise afterall. So I *know* there is a way, because I've seen programs that don't change focus when another window requests it. So how do you do it? :P Re: protecting your window from IM windows &amp; other popups Michael Dunn24-Apr-06 22:25 Michael Dunn 24-Apr-06 22:25  Well, a screen saver is a special case (in NT at least). The screen saver runs on its own desktop, so it will be the only window visible no matter what, because the interactive desktop won't be visible. --Mike-- Visual C++ MVP LINKS~! Ericahist | NEW!!
