Only one copy of the DLL will be loaded. handle0 will be equal to handle1. The FreeLibrary will need to be called twice to unload the DLL as you called LoadLibrary twice. Steve

Im not sure see How a C++ compiler implements exception handling[^] does helpful? WhiteSky

Of course, I want to do a shared function by all thread. However, I hope to only have one synchronization in this function. I means, the first thread entered the synchronize, all following thread return the reference of object directly.

Are you using VC7.1 or VC8 release canditate. As far as I remember, this is a bug on those IDEs. -- ===== Arman

Or are you using a simple text editor (like errr, notepad) and a command line compiler ? If you are using any version of visual studio, simply press F5 to start the debugger. You can put breakpoints using F9 and watch the different variables state. Cédric Moonen Software developer Charting control [v1.2 - Updated]

I think you are adding __declspec(dllexport) to the class itself. Rather add it to the functions you want to export. Press: 1500 to 2,200 messages in just 6 days? How's that possible sir? **Dr.Brad :**Well,I just replied to everything Graus did and then argued with Negus for a bit.

So I understand... However, we're pretty much stuck with VS2003 (not that I mind too much - I did when we were stuck with VS6!), although I may well sneak a crafty VS2005 onto my PC here :-) We only do native code development here, as I work for a large company, which has a tightly controlled standard Windows build, which doesn't yet include any version of .NET framework. Fortunately, I'm quite happy doing C++.

You can place the data into a shared data segment. Be sure to protect access to it with some sort of thread-safe synchronization mechanism. Any sufficiently gross incompetence is nearly indistinguishable from malice.

You shouldn't use characters outside of the ASCII range in source code, because (as you saw) the parser may interpret the bytes differently according to the code page and character set that the app uses. Use the \x notation for the string literal: L"\x6c49" --Mike-- Visual C++ MVP :cool: LINKS~! Ericahist | PimpFish | CP SearchBar v3.0 | C++ Forum FAQ VB > soccer

This is probably because the VC++ compiler is trying to optimize memory allocations, by automatically choosing the ordering and layout of variables in memory in order to minimize memory usage. -- Wessam Fathi

I'm not sure but I'd guess it has something to do with char-to-int promotion. "Let us be thankful for the fools. But for them the rest of us could not succeed." - Mark Twain "There is no death, only a change of worlds." - Native American Proverb

Thank you! Steve I wanted to know more about the auto-ending of Server. I created a ATL EXE COM SERVER and used a client to conneted and disconnected it. After a moment, in system process list, the ATL EXE process disappeared. But, I didn't know when the CoSuspendClassObjects was called. Could you tell me more details. I'm learning COM/ATL. Thank you very much! Sincerely REMY:)

Hello Remy, That's great ! You are most welcome, Remy. Best Regards, Bio.
