AnyOne Please Guide Me on my This Error <
    "Stack around the variable 'Student' was corrupted."
    
    I Receives it when I copy Members of Structure  "StudentInfo" into Structure "FailStudents" 
    using  
    list[i].FullName  =  Student[i].FullName ;
    list[i].RollNo = Student[i].RollNo;
    
    Here list is Structure Variable of Structure "FailStudents" and Student is Structure Variable of Structure "StudentInfo"

Hi

Can any one help me convert the C++ code to python 

        <pre lang="c++">char buf[1024];
	int nBufLen1;

	CString sendBuffer("$Magic $Command AudienceCount 0 10000");
	//int nBufLen1 = sendBuffer.GetLength();
	buf[0] = 0;
	buf[1] = 0;
	WORD len = sendBuffer.GetLength() * 2;
	nBufLen1 = len + 5;  // length of message

	buf[2] = (BYTE)len;
	char *pStr = T2A(sendBuffer);
	strncpy(&buf[3],pStr,len);    // actual string to send

	buf[len + 3] = 0;
	buf[len + 4] = 0;


	if(sock.Send (&buf,nBufLen1) != nBufLen1)
	{
		OutputDebugString(L"Socket Send Failed");
		return FALSE;
	}

What I have tried:

I have been trying to use seasnake, but unable to install using pip. 
A few online converter are also there, but many are not working.
