QuestionWSACancelBlockingCall Pin
Bedke2-Sep-10 2:51

Hi,
Does any one know when is this "WSACancelBlockingCall" called.
I am facing a very strange problem with this. We have a editor to write our scripts, one of the script captures a window rectangle and send it to a COM api to get the text from the image. We use FineReader as the OCR tool which is on a different server.

The problem is when we run the script through the editor it returns the correct result. However we have another script which can run the scripts in batch files, when run through this, the socket to the sever returns "WSACancelBlockingCall"

Following is the code:

CSocket RecvSockSrv;
RecvSockSrv.Create(nPort);
RecvSockSrv.Listen();

CSocket RecvSock;
//**************************************************************************************
SocketData data;
data.socket=&RecvSockSrv;
data.event = CreateEvent(NULL,FALSE,FALSE,NULL);
if (data.event==NULL)
{
// Error
}
data.nTimeOut = 15000; // Set TimeOut to 15 seconds

DWORD threadID;
HANDLE threadHandle = CreateThread(NULL,0,&ThreadFunc,&data,0,&threadID);
if (threadHandle==NULL)
{
// error during thread creation
}

int returnVal;
returnVal = RecvSockSrv.Accept(RecvSock); // Returns non zero when run through editor and 0 when the script is used.

Can anyone pls help me with this.. I want to know under wht circumstances the call is blocked with "WSACancelBlockingCall".

Thanks in advance for any help
