you just mention length '2'.

recv(new_fd,buf,strlen(buf),0)

instead use this

recv(new_fd,buf,2,0)

It seems that you find your answer but see an article about transfer file with socket on codeproject maybe it helpful for you.

In my opinion there could be many reasons for this code not working. The most important and in my opinion the one with the brightest chances is the connection not properly set up. post the full code then may be anybody would be able to help!

Hello friends,

I have an appication of recording a wave file.

But i want to specify the sound device through which only

the wave file should be recorded. That is if my machine has more than one sound card

then i want to select one (through Programmatically) and record sound from that one only.

How to do that.

Thanks in Advance.

Hi,

I get the file size and I want to format it using the format (xxx,xxx,xxx), for example:

35456931 --> 35,456,931 bytes.

how can I do it??

Like this:

CString strNum="123467890";
int len=strNum.GetLength ();
for(int i=len-3;i>0;i-=3)
{
	strNum.Insert (i,',');
}
AfxMessageBox (strNum); // Here you have the formatted string

Somethings seem HARD to do, until we know how to do them.

Here is some code that will format a number using the current locale settings:

std::string format(unsigned int n)
{
	std::stringstream strm;
	// Use current locale formatting
	strm.imbue(std::locale(""));
	strm << n;
	return strm.str();
}

This version should handle any number (int, long, etc.):

template <typename T>
std::string format(T t)
{
	std::stringstream strm;
	// Use current locale formatting
	strm.imbue(std::locale(""));
	strm << t;
	return strm.str();
}

Use GetNumberFormat() to format a number with commas (or whatever you use in your locale).

Hi,

I am using Visual studio 2005 (VC.Net). I am getting a very strange error in my application when i am calling managed code function ie. When I am loading XML file through load function with System::XML::XmlDataDocument object variable. The error message is

Managed Debugging Assistant 'FatalExecutionEngineError' has detected a problem in 'C:\TestApp.exe'.
Additional Information: The runtime has encountered a fatal error. The address of the error was at 0x79f9432a, on thread 0x3d4. The error code is 0xc0000005. This error may be a bug in the CLR or in the unsafe or non-verifiable portions of user code. Common sources of this bug include user marshaling errors for COM-interop or PInvoke, which may corrupt the stack.

Please kindly help me.
