You could use clock().
eg. Before the while loop: clock_t StartTime = clock();
Then in the loop: if ( ( clock() - StartTime ) > MaxWait ) ...
It would be better still if the worker thread didn't have to waist time and CPU cycles in this loop though. Typically worker threads use WaitForxxx for some event to occur, do whatever processing is required, and then either exit or return to the WaitForxxx function.
You might want to look at some of the socket articles here at CP and see how they handle whatever you are trying to do.

i considered this way, but i feel it's very un-effecient(nor the TIMER-Way), cos the CPU use all its time to check whether the time is over, but it can't determin which thread is more useful, every thread is treated equally.
do you think sleep() will be better? or another way?

Hello,
My program allows users print photos. How do I handle if they want to
print the same photo more than one copies? Do I really have to do StartPage
and EndPage for 100 times if they want 100 copies?
Thanks,
Hiu Sing Ngai

AFAIK, no. Have a look at the DEVMODE struct. It has a dmCopies member.
You can fill such a struct with a call to DocumentProperties, modify that single member, and set it back using another call to DocumentProperties. Please make sure the printer driver indeed handles multiple copies by checking the DM_COPIES flag in dmFields.

How do you get the red, green, and blue out of a COLORREF variable?
There's always one more bug.

Use GetRValue, GetBValue and GetGValue macros.

I got a lil problem here. I have several projects built with Visual Studio 6. Recently switched to Visual Studio.NET and found that it compiles/linkages all projects using MFC7 dlls. Of course it is not working on OS that doesn't have .NET framework installed. And this is not a good point. So my question is: is it still possible to use MFC6 in Visual Studio .NET and how to do that?
I even created a simple Test application with MFC, and tried it on Windows 98... "Get me MFC7 now!" it said 
I hope there is some way to do that, otherwise I'll have to bring the VS.NET back to store, no use of it then

MFC 7 works perfectly fine without the .NET runtime installed...

No, VS.NET comes with MFC 7 and that's what it uses. I'm an advocate of linking MFC and CRT statically so you never have to worry about the MFC DLLs. MFC7 does not use or require the .NET framework.

But doesn't it eat up all your memory if you have more than one of this kind of programs?

You're blowing things way out of proportion. It doesn't use "all" your memory. Each executable image will be larger, however that is preferable to having to debug screwy problems caused by different DLL versions, which will appear to be your fault because, hey, your program is crashing.

Sure, but there is always a trade-off

.NET framework is not needed. You need to distribute MFC7 dll files with your app.
See informations about redistributable files in MSDN.

Yeah, thanx. Looked around, read some MSDN help that comes with VS.NET... Well redistributing MFC7 is better than the whole .NET framework, although it takes like 4Mb  *sighs*

MFC libraries have nothing in common with .NET Framework except that MFC7 is part of VS.NET studio. MFC is classic unmanaged C++ library. .NET is from another world.

I have not used VC7 yet. If the .NET framework is not required for programs written with VC7, then what is .NET framework for?
|

You can write programs of two kinds using VC++ 7, unmanaged and managed. Unmanaged programs are using WIN32 API and optionally some libraries like MFC or ATL, nothing from .NET, it's the same programming as in previous versions with new IDE and some new features in libraries and compiler. Managed ones are interfacing with .NET framework using MS specific language extensions. .NET framework is an environment very similar to Java with bytecode(called MSIL here), garbage collector, objects and interfaces, rich libraries, see this[^].

Hello there,
It's my string that i added to Rich edit box:
Ali
Hadi
Asghar
I wrote them by my own function AddText:
AddText(m_Rich, "Ali\nHadi\nAsghar");
The problem is when i get the len, i got differet results in different OS ...
As i can remember, the result was same in Win98 and WinXP
But len was different in Win2000 
I think the problem in for Enter character !
So, how can i get real len in Win2000 ???

Thats a weird one.

I count 3+1+4+1+6 = 15
But the enter and lf would quite possible make 16 || 17
If it's a CString could you not perform a simple Replace on the text before input eg
m_Rich.Replace("\r","");
or use
m_Rich.TrimRight();

Hello Colin 
And thanks for reply ...
I used CRichEditCtrl, not CString !
In my real program i added the text like this:
AddText( "Ali" );
AddText( "\nHadi" );
AddText( "\nAsghar" );
Could u solve my problem from above code ??
I didn't understand why you used m_Rich.Replace("\r",""); 
Please help me ...

Does anyone know how I can set a timeout value for the connect() method of a socket? If it can't connect within about 200ms then I know that it never will.
At the moment the connect is waiting for about 5-10 seconds before it returns.
My code below:
<br />
target.sin_family = AF_INET;<br />
target.sin_addr.s_addr = *(long *)(host->h_addr);<br />
target.sin_port = htons(port);<br />
s=socket(AF_INET,SOCK_STREAM,0);<br />
<br />
if (s<0) exit(printf("Error creating socket.\n"));<br />
if (!connect(s,(struct sockaddr *)&target, sizeof(target)))<br />
{<br />
}<br />
if (closesocket(s)) exit(printf("error closing socket.\n"));<br />
<br />

I think you can use Winsock's "select" statement. Take a look at that along with the TIMEVAL structure.
Oh yeah, that only works on Winsock 2.0

Using Visual C++.NET, I want to insert a IWebBrowser2 control. I have created a class with the "Add Class" wizard choosing "MFC Class From ActiveX Control". It worked fine and the class was added.
I then add 2 controls in my dialog. How do I bind them to variables of the class I added. When right-clicking on the control, the "Add Variable" item is disabled from the context menu, and the "Add Class" don't show the ActiveX class from the drop-down.
How do I do it? It was so easy in Visual C++ 6.0, but now it seems very difficult.
