Is it possible to invoke any class written in java within VC++?
I know, the vice versa is possible by "native " keyword and compiling with javah.exe and so on...

Anyone know of a pixel perfect correct way to determine the width/height of various control parts, thqat takes into account the current font used for the control?
For example, what are the correct dimensions of the a standard check box or radio button?
What about the proper height for a combo box or push button?
GetSystemMetrics() only covers certain general things. Any other solutions? I have tried to create a function that works out the pixels given a value in dialog units and a font, but this doesn't seem quite right.
For example, if you wanted to create a custom control that gets used as a header, how would you accurately determine the default header height so it matches to what the header in the ListView control has?

Hi guys, i'm writing an intros but it drives me crazy when someone says:
"Hey it says that i have no msvcrt/d.dll"
Is there any chanse to link those dlls so their copying into the intro dir wouldn't be needed?
Grtz.

You have two options.
1. Don't use the c run time - use C++ functions.
2. Distribute the msvcrt dll
Also, NEVER distribute a debug build, so that no-one ever asks you for a debug DLL again.

Hi!
I'm writing a program which needs to recieve a lot of data though a socket. Another application sends a lot of small portions (like 50 byte) of data (measurement data) to it over the network, like 1000 messages per second.
Which socket communication is the best/fastest? Right now I testet a blocking CSocket in its own thread, but that really slows down the machine. But how should I do instead? Any tip? Should I use CAsyncSocket instead, and how? Blocking or non blocking?
Thankful for any suggestion!!

I used
SetWindowPos(NULL, 0, 0, 100, 100, SWP_NOZORDER);
in OnInitDiaolog() (msvsC++6,.NET, dialog based project)
and as a result window appeared in the middle of the screen.
Then I try SetWindowPlacment(), it works, but only if window not hidden at startup.
How can I move window to (0,0) in OnInitDiaolog()?
(at present I use SetWindowPos(NULL, -1, 0,...)

Perhaps you need to clear the dialog style's DS_CENTER bit?

No. With DS_CENTER all ok (it's not set). Function works correctly if you set any position except (0, 0). If you move window in (0,0) window appears in the center that's my problem.

Are you talking about gethostname()?

It belongs to no class. It's just a Win32 function.

Hi.
I'm developing a program with visual C++ that creates multiple threads and each thread creates a new instance of the same DLL (which I have the the code, but I didn't developed it).
The problem I'm having is that when I create the first thread, the DLL is instantiated correctly but when I create the second thread and try to create a new instance of the dll, I didn't actually create a new instance, but just makes an instance of the DLL already instantiated, and so I overwrite some variables and stuffs like that.
If, instead create two threads I execute the program twice, running at the same time, I can make new instances of the DLL. Why in this way I can make a new instance of the DLL and using threads I can't?
How do I know if the DLL was created as a multithreaded DLL?
And another question is if the DLL wasn't created a multithreade DLL, how can I change this?

This is not about multithreaded dll - this is how the windows handles the dll libraries - it is loaded only once in the memory for saving resources. When you call subsequent LoadLibrary it simply increments the usage counter.
If you LoadLibrary from other process, it is a different story. There are some nifty stuff inside the windows, but for you it's like the dll is loaded again --> you can load your library only once into process memory.
Difference between library compiled as multithreaded or singlethreaded is AFAIK only difference with c runtime support libraries used. If you will not use functions like printf etc, there is no difference between dll compiled as multithreaded or singlethreaded.
There's no way, how to determine, if the dll was compiled as multithreaded, neither way how to change it (without having sources and recompile).
But for your problem as you described, it makes no difference I guess.

There are quite a few run-time library functions that have global/static variables whose storage specification changes for the multithreaded versions. The multithreaded versions use the __declspec( thread ) keywords to specify thread-local storage for those variables which means that each thread gets its own copies of each variable.

Thank you. Didn't know it. Or better didn't think about 
I just got it as - I don't know which functions have some global/static parts and I don't know if it can or cannot change. Therefore I decided to took the run-time library as a block - either use it, but then compile carefully with appropriate switch or dump it completely.

I'm not using LoadLibrary method.
I'm importing the .tlb of the DLL file and then linking to my program.
To create a new instance of the DLL, im using the methods CoInitializeEx with the parameters 0 and COINIT_MULTITHREADED and then CoCreateInstance with the parameters CLSID_DLL, NULL, CLSCTX_ALL, IID_IUnknown, (LPVOID*)&pointer);

CoCreateInstance does some COM dancing around and then calls LoadLibrary for you.
