I've found it hard to find any benchmarks that I can trust. If I was going to use dotNET I'd use C#. The main problems I have with dotNET is firstly memory consumption and secondly the speed. Many dotNET supporters concede that the memory consumption is high but say RAM is cheap. I don't buy this argument: as a developer I have many, many applications open at the same time - If they all consume heaps of memory then the computer will start paging sooner and the whole system suffers.

hi frnds,
this error come due to parameter conversion failures.... but i hav tried for the best....
anybody having some better n easy solution...
line that is having error in my code....
DWORD dw=nthol(i_net(Ip.Getbuffer(MAX_PATH)))
Ip is a CString class.....
|
|

|

Just a wild guess here,
Is inet_addr what your looking for?
|
|
|
|

Well, for starters, your missing a closing parenthesis.
secondly, no need to use CString::GetBuffer() when you are needing a const char* since CString already has an operator for that. Only use CString::GetBuffer() when you need a buffer to pass into something. It won't hurt you here except you forgot the corresponding ReleaseBuffer() but that's a different story.
Thirdly, C++ is case sensitive so that call to strIP.Getbuffer() won't get you anything except another error to add to the list. strIP.GetBuffer() is probably what you meant.
Fourth, I took your code and fixed the above statements, included the #include "winsock2.h"
and made reference to ws2_32.lib and I was able to compile it and run it so I'm not sure what your fighting...
CString strIP="192.168.1.1";
DWORD dw=ntohl(inet_addr(strIP));
TRACE("Big Endian dw = %u\n",dw);
Any additional data in the time since your last post?

what is i_net() function?
what is nthol() function is it supposed to be ntohl()? Which takes a u_long parameter so why would you be getting it from a CString object? I cannot understand what you are trying to do.

YEAH U R RIGHT....
I MISTYPED THE CODE....
CODE IS...
DWORD dw=ntohl(inet_addr(strIP.GetBuffer(MAX_PATH)));
strIP IS A CString class...
error message i m getting is...
C2664: inet_addr()..can not convert parameter 1 from "unsigned long *" to "const char *"
i m using eVC++4.0

inet_addr() take a "const char*" parameter. If your project is Unicode you cannot get an ASCII char pointer directly from CString. There are string conversion macros that have changed with versions of VC,ATL,MFC. Using the latest version would look like this:
CString strIP(_T("122.23.220.44"));
CW2A charIP(strIP);
inet_addr( charIP);
See the documentation[^] for more complete information about the different macros and versions of them.

Hi,
Simply add an Animate control on ur dialog
Then add a member variable for it.
Add "avi" in resource( IDR_AVI )
CAnimateCtrl m_aNimate;
m_aNimate.Open( IDR_AVI ) ;
m_aNimate.Play( 0,-1,-1 ) ;
"Dream bigger...Do bigger...Expect smaller"

its not the dialogue based,its a Win32 application...it wont support the things u send ......

Do you want a realistic waterfall, or just the illusion of a waterfall?

Well...that's pretty advanced, but, typically with any water effect, you need a water texture, and then you animate the texture by changing the texture coordinates. If you want realistic waterfall, you'd also need a particle engine to create mist.
I don't have any links to tutorials or code, maybe google for "opengl water tutorial" or poke around on http://nehe.gamedev.net/[^] (that's the second time I've linked to nehe today, what's up with that?!)

yeah i hv checked that link, i want ur verdict on a thing i-e i have downloaded an animated waterfall , itb has 20 frames. now i was wondering may be i shud load each frame using threads, shud i go for multithreading

Multi-threading is not the approach I would take. Is the animated waterfall an .avi? If so, check out Lesson 35 on the nehe site.
