How to use ADO to insert BYTEA data?

[sunpeng <bluevaley@xxxxxxxxx>]

I try to write this code for postgresql (for mysql working fine):

try
 	{
 		m_pRecordset->AddNew();
		iTimes++;

 		VARIANT bitdata[3];

 		SAFEARRAY *psafe[3] = {NULL, NULL, NULL};
 		SAFEARRAYBOUND  band[3];
		
			bitdata[0].vt = VT_ARRAY | VT_UI1;
			band[0].cElements = FreImgSize;
			band[0].lLbound = 0;
			psafe[0] = SafeArrayCreate(VT_UI1, 1, &band[0]);

			for (long iSize = 0; iSize < FreImgSize; iSize++)
			{
				SafeArrayPutElement(psafe[0], &iSize, &pFreImg[iSize]);
			}

			bitdata[0].parray = psafe[0];
			if (bitdata[0].parray != NULL)
			{
				m_pRecordset->GetFields()->GetItem("CapturePic")->AppendChunk(&bitdata[0]);
			}

When calling AppendChunk error occurs.
Please help me, thks!
