DS_OpenEx fails, error creating default control

[Changchih]

Hi 

I'm using datasocket to get data from a website and find this fatal error sometimes where DS_OpenEx is called

ComponentWorks
Error creating default control

I'm using Labwindows CVI 2012 sp1, windows 7 64bit,and DS_OpenEx is called in a thread

CmtScheduleThreadPoolFunction (DEFAULT_THREAD_POOL_HANDLE, getData, NULL,NULL);

int CVICALLBACK getData (void *functionData)
{
......
while(1)
{
Delay(0.05);
res = DS_OpenEx (url, DSConst_ReadAutoUpdate, NULL, NULL,DSConst_PollingModel,10000,
&dsHandle);

if(res == E_DATASKT_TIMEOUT_EXPIRED)
{
continue;
}
......

DS_DiscardObjHandle (dsHandle);
}

return 0;
}

this error occurs randomly.I have no idea about how it happens.

Can anyone help me? Thanks in advance.
