1.One socket with 2 threads do read/write,is that ok?
2.One socket with 2 threads write to that socket with no lock,could the OS provide the receiver's pack oreded,that is,if thread A and thread B send message to the same socket with no sync protected,for exp A send "AAAA",B send "BBBB",is is possible for the receiver socket recive AAAABBBB(ordered) or ABAABAB(disorederd).
3.If using WSASend api to send a buf to several sockets,can we simply use a loop to send like following examples
WSABUF buf;
buf.buf = "test";
buf.len = 4;
Socket list[someNum];
for(i = 0;i++;i< someNum)
{
WSASend(list[0],&buf,1,...);//here we keeping use the same buf!!
}
if its not so correct,is there any good solutions?
Best regards!

Hello everyone!
I still don't quite get how C works... I always get weird, and I mean weird errors, like this one:
I have a char* string. It's a filename. If I printf() it, it gives me "x5" or other characters that don't have anything to do with it. But if I open the file, it opens correctly, and I can even display a string on the file...
Why is this? Is there a tutorial or something that explains this kind of stuff? Thanks!

I need some help converting between TCHAR strings and ASCII strings. (I understand that the actual type for TCHAR is decided by the compiler switches.) In this case, TCHAR is UNICODE. But I have a char* string passed into my function that I need to deal with. My questions:
What's the best way to convert the char* string (array) to TCHAR? I'm doing it one char at a time in a loop, but I am hoping for something more elegant.
How do I handle the ASCII end of string in TCHAR? For example, in one section I need to loop through the characters in the TCHAR string. I want to stop if I hit a new line from the char* string. That's easy in an ASCII string, but in UNICODE... well it's probably just as easy if you know what to look for!  Should I be looking for TWO TCHAR characters (0xA and 0x0)? or something else?
Thank you!

Place the macro USES_CONVERSION at the beginning of your function. You then have access to all of the string conversion macros. You can convert between any of ACSII (A), OLE (OLE), WIDE (W)and TCHAR (T). To convert ASCII to TCHAR do the following.
LPSTR *lpSrc;
LPTSTR *lpDest = A2T(lpSrc);
Similarly T2A, A2W, W2A, A2OLE, etc can be used. You can also put a C after the 2 to get a const string returned.
The good thing about these macros is that if you build the application with _MBCS defined, TCHAR is the same as ASCII so the A2T macros becomes nothing. If you build with _UNICODE defined then it will allocate a buffer and covert to Unicode for you. The memory is allocated on the stack with _alloca, so you can't keep the converted string after the function returns without taking a proper copy of it first. Also don't use inside a loop because it could allocate a lot of memory if the loop iteration is large.

If you use the newer ATL7 conversion macros then you do not have to use USES_CONVERSION and you can safely use the conversion macros inside a loop.

Thanks, this works fine. But I am wondering how the macros work. I followed the code and see that it ultimately ends up at defs for MultiByteToWideChar and others. But of course the code is not shown. So I wonder if this is implemented as just a big lookup table or if there is some better way to approach this.
Obviously this question has become somewhat academic at this point. My initial problem is resolved. But I am just thinking about how I would have implemented this and I don't see a better way than using a big lookup. That seems too clumsy.

An alternative to using the ATL macros is to use the _bstr_t class. It has constructors that take both ASCII and WIDE character sets, and have overloaded operators for both char* and wchar_t*. It will end up calling the same functions in the end (the MultiByteToWide, etc.) but it easier to read and debug since it isn't a macro.

Hi,
Im writing a webserver which loads an exe file as cgi application. What im trying to do is not make the window popup each time someone visits the site.
I still need the process visible in taskmanager though...
Heres what im using at this point to load the cgi app and get the std out... which is what i need to do...
char psBuffer[1024];
FILE *pPipe;
send(AcceptSocket, header, strlen(header), 0);
pPipe = _popen("test.exe", "r");
//..other functions
_pclose( pPipe );
Any Help on this matter is appreciated.

I assume you've got a console window popping up. If you make the exe a normal Win32 project instead of a console one you will not get a console window popping up.

Thnx.. I dont think thats going to help in this situation.. because if users were to write thier own cgi.. they would have to do the same.. and such is too much to ask in my opinion... Theres got to be another way to hide the bloody window...
|

Assuming you're on XP (or better..) can't you just run your Web Server as a different user - this way the web server will have a seperate desktop, on which any cgi programs will run

I work with vc++ 6 (don't lough).
I have an MFC project with a resource file created by the MFC wizzard.
I can not run rc.exe on this file. It says "RC: fatal error RC1107 :
invalid usage: use rc /? for help"
I have no problems running rc.exe my own (simple) resource files.
I assume that VC runs rc.exe with some more defines/swithces.
Can anyone tell me how should I run it (and succeed) ?
Thanks
Maurice
