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.

Hi I have Dialog based mfc applciation using visual studio 2013.

Dialog contains multiple controls. It has two threads - main ui thread and worker thread

In a particular control (some static test)  i have to show some counts (like number of Cars produced 

and Number of Bikes prodcued, and total ). Actually these counts are given by worker thread. 

Worker thread continuously gives the counts (that is live data)

I have to update UI from main thread based on these data lively.

Please help me to design this use case. My ui contains multiple controls. I don't want to block the UI

How to pass the data(counts) from worker thread to main thread? how to avoid block in main thread?

Is there any need for queue or another thread?

That is UI will be some thing like

 number of Cars produced:10 

 number of Bikes produced: 20

Total: 30
