Vlad, obviously we have difference of opinion. I also respectfully disagree, I did not state that we do not need background being erased in all cases, I stated in majority of cases. As (I think Chinese) saying goes, picture is better than a thousand words: I have attached 2 zip file with four different executables, illustrating your first and second use case. In each case suffix _E denotes CS_HREDRAW | CS_VREDRAW class style used to create...

1. What is piArrVal and how is it used? 2. How do you create/update the pi[10] array and what does this magic number "10" mean??

I'm with JohnCz, I have 2 child windows (not inc. controls) that I set to resize when the main window is resized. I have both my main and 2 child windows with their styles set to 0 and I'm having no problems at all when I resize the main window, they're correctly resizing and not flickering at all, one of them is even rendering Direct2D and not having any problems.

Hi, I am using PROCESS_INFOMATION structure to get process status. I used it as global array variable. PROCESS_INFOMATION pi[10]; So, for every process creation, I incremented the array element. In seperate thread, I am using WaitForMultipleObjects() to get process status. after WaitForMultipleObjects(), i am using for loop to get which process terminated. Code: for(i=0; i<10; i++) { if(Result == (WAIT_OBJECT_0+i)) { pid =...

I checked those dll files and after some googling i found that i need to put those dll files inside "c:\windows\winsxs\x86_Microsoft.VC90.CRT_<some random no here>" of the target computer before running the application. so how to generate this directory path at the time of package installation. ?

A common cause of flickering is when the background of a window is painted again. You can avoid it in classical C programming with these three lines in your message loop: Code: case WM_ERASEBKGND: return(1); // Prevent erasing the background to reduce flickering break;

You tell us if it's possible. Who knows your app better than you do? Did you ever attempt to understand what in fact happens in your app? Does it crash on something related to your service, like shared memory, pipe or socket? Or actually gets terminated by OS? Did you try to launch it manually and see if it survives in this case?

The rule is: never paint the same pixel twice. If you are erasing your background, then drawing on it, you are painting at least some pixels twice and you get flicker. You can either take elaborate steps to ensure that you only paint specific areas at specific times, but that gets complicated quick. A much easier way is to do all your drawing to memory, then when everything is done, paint the memory to the screen in one step. This is known as...

Quote: Originally Posted by JohnCz You need this behavior in some windows but in majority of cases, redrawing is undesirable. I respectfully disagree. There are many cases where you DO need those styles: - if your view is scrollable - if you scale it when window is resized - if you change layout (move / resize controls) This basically leaves only ONE case when you don’t need them: - if you only show whatever part of content fits in the...
