RECEVING BINARY DATA using WINSOCK

[pfaisalbe]

Hi

I am using winsock to receive binary data from an electronic device. PC and electronic device are in adhoc configuration. My C code works very well but VB.net code doesnot work well which gives data which are not in binary.

Here is my C code first


int nlen = 32768;
char SendBuf[800],RecvBuf[65535];
i = 0;

FILE * pFile;
pFile = fopen("mybin.bin","ab");

while(i != (nlen + 3))
{
recv(m_socket, &byte, 1, 0);
RecvBuf[i] = byte;
i++;
}

fwrite(RecvBuf, 1, nlen + 3, pFile);





Hers is vb.net code


i = 0
j = 0

'For i = 0 To 32768 + 3
SOCKET.GetData(sData, VariantType.Byte, eventArgs.bytesTotal)
SOCKET.Refresh()
FileOpen(iFileNumber, Environment.CurrentDirectory & " mybin.bin", OpenMode.Append)
PrintLine(iFileNumber, sData)
FileClose(iFileNumber)
'Next




What is the error in VB.net code


Please suggest

What data type is the variable sData? If it's a string, that would explain why the data does not appear to be binary. I would use an array of bytes.

I have used sdata as byte data type

Thanks
