Hello,
when I change the window size from the top or the left edges, I get flickering in the client, my program opposed to the usual behaviour want the client clipped from where the user resize the window and not always from the bottom and right. I couldn't find where windows draws the DC. if anyone could understand my poor english and also have any idea how to solve this problem, I'll appriciate it.
Thanks,
BishGada.;)

try overriding the WM_ERASEBKGND message with an empty function.
The default operation of the framework is to clear the window with its background colour when this message is recieved, which is probably what's causing the nasty flickering

thanks, but thats not that kind of flickering, I already override the erase bg the problem is that windows scroll the DC and thats what I want to prevent.
thanks anyway.
BishGada.

hi,
what method do you use to terminate a thread?
i am in a situation that after few thousands of restart a thread? it failed for me to create thread for me with AfxBeginThread().
i used TerminateThread() to terminate thread from the main program, in msdn, it is not a good method to terminate a thread.
i guess it leads to the problem that i can't create thread when restart.
do you have any good method to terminate thread?
thanks,
jim

You can usually end your thread from within the thread with Afxenthread(); If you want to do that remotedely from outside the thread, just use an event to tell your thread to end.
~RaGE();

hi,
i found that the thread would not terminate immediately after call AfxEndThread(). since i used TerminateThread() to terminate another thread at the same time, so i can observe such difference.
is it normal?
thanks,
jim

There are couple of ways to terminate thread safely based on the problem
here is the event approach,
- CreateEvent() (named event to use across process'es)
- CreateThread (or AfxBEginThread) and pass event as Thread Param
- Keep listening to Event Signaling at application atomic times (WaitForSingleObject).
- when Event is signaled or job is done, just return (use AfxEndThread() with AfxBeginThread() - MFC way)
From main/any thread signal the event, when u want to stop the thread safely.
To brutally kill the thread use: TerminateThread()
Refer to samples in codeproject.com OR codeguru.com.

Ramu,
thank you! your information is so useful.
currently, i am using a TerminateThread() to kill a thread.
due to some reasons, i need to restart the threads few mins once. after few days running, it failed to to create thread with AfxBeginThread(). i doubted that related to using TerminateThread() to kill a thread. so, i am trying other methods.
anyway, your information is useful and let me check with it!
thanks,
jim

does anyone know how can i use the MFC'S CBitmapButton?
thanx
|

CBitMapButton myBitMapButton;
You are now using CBitMapButton. You didn't say what you wanted to do with it, but there are only 2 methods, so it can't be hard to figure out. Look up CBitMapButton in MSDN.

I'm working with a class(CSizingControlBar, or CSCBar) derived from CControlBar, and I want to place CSCBar at a MDI's child Frame, such as the main view window. But these CSCBars can be placed anywhere of the screen, i don't like it. i want to the SCBBar behave like the child Dialog.
how to realize? thank you. ;)
Best Regards!

I want to add in the standard help file for my VB/VC++ application. Any VB6.0/VC++6.0 built-in tools can be used for this purpose? If not, any alternative can I choose?
Thanks

In that case look for a slightly older version of the same file under :-

How can I get info about printer paper tray alignment under W2k, XP ? It was possible to do it (Win98, 95, ME) using DeviceCapabilities with DC_BINADJUST parameter, but this one is now not supported. I need to know it when printing on custom-size paper to set starting offset.
Thanks
