C++

I am developing project in which I want to capture video from two webcam at same time from two different side.
But when I started recording from both webcam it shows "END RECORDING" status ;
But when I started recording single webcam it record a video.
I am mentioning the code used for recording.
Also I am using vfw32 library of Microsoft Sdks for this webcam functionality.

//CONNECTION FOR WEBCAM1

hMyWindow1 = capCreateCaptureWindow("", WS_CHILD |WS_VISIBLE,rect.left, rect.top,rect.right,rect.bottom, hw, 0);

capSetCallbackOnStatus(   hMyWindow1,    capStatusCallback1);

SendMessage(hMyWindow1,WM_CAP_DRIVER_CONNECT,0,0);

SendMessage(hMyWindow1, WM_CAP_SET_SCALE, true , 0);
SendMessage(hMyWindow1, WM_CAP_SET_PREVIEWRATE, 66, 0);
SendMessage(hMyWindow1, WM_CAP_SET_PREVIEW, true , 0);
SendMessage(hMyWindow1,WM_CAP_DLG_VIDEOSOURCE,0,0);


//CONNECTION FOR WEBCAM2

hMyWindow = capCreateCaptureWindow("", WS_CHILD |WS_VISIBLE,rect.left, rect.top,rect.right,rect.bottom, hw, 0);
