I want to tell the program the receipient IP address....if not the program will not work.....it will execute till the printf statement " USAGE: udpsender <receiver ip="" address="">."
I have yet to modify the program with the IP address I want it to be.....
The rest of the statement won't be executed....
Also I need to put in the receipient IP address 172.20.145.45 so that I can transfer data from one PC to the other PC.....
I cannot just assume the IP is correct....

I am writing a program that interfaces with Flight Sim 2002 and 2004. I am writing this in .NET VC++ 7. I have one 100ms timer, and I am currently testing the program with only one funtion call. Every 100ms if a few variables are met the program accelerates the aircraft (writes a new velocity value to FS). That's the theory... in reality it only writes about once every 2-3 seconds or so. How can I make the program run faster, at a higher cpu priority, or whatever?

Is the timer actually firing every 100ms? I'm not sure of the answer but if the timer is at fault you may try using a mm timer instead of the standard WM_TIMER..

The timer fires fine when it is the only program running. When it has to share processor space with Flight Sim it fires UBER slow. It isn't flight sim or my pc because other add ons and program seem to respond normally. It has to be the default priority .NET assigns the program, which has to be LOW.

The mm timer doesn't rely on Window Messages, I believe it's more hardware orented. Being that the system is busy with the Sim program windows may be dropping the WM_TIMER messages... I would consider looking into using the mm timer instead.. I have some used it in app's where the timer portion is critical..
You can find samples here on cp and on codeguru.. If you have any problems i can post some of my code..
(only bad thing is my examples are in VC++ 6.0 not .NET)

Long back i had used some api to convert the file size in bytes in terms of KB,MB, etc
does any one remember that api.
Thanx in advance.

//Replace NULL with a pointer to a variable that holds the high-order size
//if the file is larger than can be represented by a DWORD
DWORD bSize;
DWORD kSize;
DWORD mSize;
bSize = GetFileSize(hMyFile, NULL);
kSize = bSize/1024;
mSize = kSize/1024;
Sorry; couldn't find anything else.

humm, thanx any way for replying actualy this is not what i was looking for,
suppose x = 1025
then there is a function which gives the following ouput
CString t = somefunction(x); //t = "1 KB"
any way i made that function myself that does that.

StrFormatByteSize. Defined in shlwapi.h and requires linking to shlwapi.lib.

I figured that, but having checked the Win32 functions, MFC reference, and run-time reference and finding nothing, I gave up. I should have just looked in MSDN[^], though actually finding anything there is often a challenge.

I'm trying to retrieve information through software about the system's chipset. Things like the brand, model#, revision# etc...
Would somebody be able to point me in the right direction? 
Thanks heaps!

Hey all
Just wondering if anyone knows of an "easy" way to get the computer's HOST name? (The host name of the computer that is running the application?)
Thanks!

ummm...how about GetComputerName()?

I've been reading a handy book I bought a while ago, but never got around to opening, called Microsoft Windows 2000 API SuperBible. It obviously was never a best seller, as I got it for $15 on the discount shelf, but it's full of thousands of API descriptions and examples in C++. Neat stuff I can get into real mischief with, like BlockInput(TRUE) and ExitWindowsEx(EWX_FORCE, NULL). It even identifies which OS versions (Win2K or Win9x) each call applies to, and points out usage differences if they exist.
Now that WinXP is the OS of the week, to what extent does XP add to, or invalidate the Win32 API that was current as of Win2K?

Hi!
I think it maybe a question difficult to answer. But I hope there are some people share the same experience with me will give me some hint.
I find one dll project very weird.
There are some functions in the dll to be export. They are declare with _declspec(dllexport).
But some function(about 5%) can't be find in the generated dll. (I used ultraedit to search for the name in the dll binary)
I finally find out it have some relation to its parameter. for example
int funcNoUse(long lRegionID)
{
return 0;
}
will be ok, it's generated in the dll.
But if i change it to
int funcNoUse(long lRegionID, long nPoints, float* pY, LPCTSTR szFlags, int makeCopy)
{
return 0;
}
it will not exist in the dll.
I really don't know what's up. I have test it on two computer one with VS7 and another with VS7.1 have the same result.
any idea?

Sounds like you be being a victim of "Name mangling". This is something the C++ compiler does so that overloaded functions with the same name but different parameters can be properly resolved by the linker. You can force the compiler to turn of "Name mangling" for a specific function by using extern "C" in the function declaration.
extern "C" int funcNoUse(long lRegionID, long nPoints, float* pY, LPCTSTR szFlags, int makeCopy)

Message digest is something similar to digital signature. I would like to insert it in my mp3 id3 tag. There is an extended header that has variable length in id3 tag. How can I add message digest in the extended header using visual c++?
|
|
|
|
|
what ? say that again ?
AFAIK, you can pretty much insert anything in an mp3 ID3v2 tag. have a look at http://www.id3lib.org[^] for more info on id3 tags.
