Thanks for the links to the article and books. I'll look into them.
By the way, it is important to me to know when all threads are done so the code can proceed to release resources. The background threads are somewhat short-lived since they just generate a synthetic HTML page and send it to the requesting client. The foreground thread waits until all background threads (if any) are done and then deletes the server object.

I don't like polling, so I always use WaitForMultipleObjects()
I would have liked if they made it possible to have an event signaled every time the sempahore is in an unused state. You could simulate this by writing a small function with a critical section with the semaphore code inside and a counter.
Anyone who thinks he has a better idea of what's good for people than people do is a swine.

If you want to use GetSemaphoreCount(), try Linux 
In windows, such function could be
long GetSemaphoreCount(HANDLE hSem)
{
long tmp=0;
if (WAIT_TIMEOUT!=WaitForSingleObject(hSem,0)) ReleaseSemaphore(hSem,1,tmp);
return tmp;
}
Good luck

#define *** 0x000000AE
For hours now I have been trying to find out why my code was not working. It's that above message!! I've been playing with the icon on the titlebar and for some reason everything I did was painted over, even though I trapped just about every message I could think of. Through the aid of spy++ I found the culprit!

I believe it is undocumented. In WinUser.h the closest value is :
#define WM_NCXBUTTONDBLCLK 0x00AD
|
|
|
|

That was the first place I looked. A search on google has only revieled a few symbian references, nothing which would have an effect on what I am doing. It is sent prior to a WM_NCCALCSIZE message, with 0x04 in the wParam. I trapped it and returned 0, my app worked. Until I restarted VS when all of a sudden trapping it had no effect.
It doesn't matter, I wrote a function to bypass the whole routine. I now an animated icon on the title bar, and a static icon on the taskbar, switchable of course  )

I doubt it, most of the code is hijacked and modified to suit my needs. I think writing an article about this will get me into trouble. All I wanted was to create a re-usable library which would enable me to show animated icons, and to minimize the window to the tray (animated not just hide).
This is the first time for me to subclass a window. In MFC probably very easy, but for plain old Win32 it takes a few lines of code.

How do I set the background color of an individual edit box? Say it is IDC_EDIT1 and I want a red background with normal black letters.

Create a brush and override WmCtlColor()..i think that's the one.

Black letters on a red background are not very contrasting and thus may be hard to read.

I look for any function that can get me date that OS Windows was installed on the PC. From command line I get this information by running systeminfo, but I need this from Visual C++.
Please help.

Can you shell execute this command within your code?

I think WMI will be your thing.
Take a look at 'Win32_OperatingSystem', there's an InstallDate property.
Don't think you are, know you are...

Good answer![Rose | [Rose]](https://www.codeproject.com/script/Forums/Images/rose.gif) I thought about WMI, but did know Win32_OperatingSystem has a InstallDate property.

I have an Edit control in my dialog box that takes a 10 digit number, now my requirement is after entering the number in the control, i will hit the return (enter) button in the keyboard for some validation to take place.
remember only with the pressing of the enter key in my keyboard, the validation should take place, i have tried handling the ON_EN_KILLFOCUS and ON_EN_CHANGE notification messages but in vain!!!
i have also tried enabling the Want Return style of the edit button but still i am not able to achieve the task, pls help??
thanx in advance

You can try to put button near the edit control and make it a DEFAULT button. Then, after you insert the number and press Enter, the default button will be pressed. So you can validate the input.

Use PreTranslateMessage with VK_RETURN

If you are simply wanting to validate the contents of the edit control when it loses focus, just handle the EN_KILLFOCUS notification. Messing around with the Enter key and/or the EN_CHANGE notification is not necessary. Now if you want the OK button disabled until a valid number is entered in the edit control, that is a different problem requiring a different answer.

I have noticed that the on-kill-focus is not called for cases where the focus really doesn't leave the control, for example clicking on an icon or perhaps when you press the enter key? What I have done is to force a focus change. The first statement you should have within your method called by the enter click is to set focus somewhere. See if this then calls you on-kill-focus method for the edit box.
If only I had more time!
