__vtblIFacePtr->lpVtbl->CaptureImage_ error

[nallav]

HRESULT CVIFUNC RemComVNCIF_ICRemComInterfaceCaptureImage (CAObjHandle objectHandle,
ERRORINFO *errorInfo,
const char *bstrDevIP,
const char *bstrImgPath,
VBOOL *pRetVal)
{
HRESULT __result = S_OK;
RemComVNCIF_ICRemComInterface_Interface * __vtblIFacePtr = 0;
int __didAddRef;
int __errorInfoPresent = 0;
BSTR bstrDevIP__AutoType = 0;
BSTR bstrImgPath__AutoType = 0;
VBOOL pRetVal__Temp;

__caErrChk (CA_CStringToBSTR (bstrDevIP, &bstrDevIP__AutoType));
__caErrChk (CA_CStringToBSTR (bstrImgPath, &bstrImgPath__AutoType));

__caErrChk (CA_GetInterfaceFromObjHandle (objectHandle,
&RemComVNCIF_IID_ICRemComInterface,
0, &__vtblIFacePtr, &__didAddRef));
__caErrChk (__vtblIFacePtr->lpVtbl->CaptureImage_ (__vtblIFacePtr,
bstrDevIP__AutoType,
bstrImgPath__AutoType,
&pRetVal__Temp));

if (pRetVal)
{
*pRetVal = pRetVal__Temp;
}

While capturing the image in RemcomInterfaceCaptureImage function using CaptureImage_ (),pRetVal__Temp value is updated to 1 instead Zero.I am getting an error here. I have searched for CaptureImage_ function description, but I have not received any info in LabCVI2012 help. 

HRESULT ( STDMETHODCALLTYPE __RPC_FAR *CaptureImage_) (RemComVNCIF_ICRemComInterface_Interface __RPC_FAR *This,
BSTR bstrDevIP,
BSTR bstrImgPath,
VBOOL *pRetVal);

Can you please help us understanding about this function?

The tool you are using for image acquisition appears as an external piece of software which you are interfacing to via ActiveX; this is the reason why you cannot find any documentation inside CVI help: you'll need to search for the appropriate reference in internal tool documentation or ask the software vendor.
