Insert bytea type into PostgreSQL

Hi,

I'm having a problem right now getting error message "Operation is not
allowed in this context" when I'm trying to INSERT/UPDATE to Database.
I'm using Visual Basic (ADO).

This is the code :

Dim rs As ADODB.Recordset
Dim varImg As Variant
Dim varChunk As Variant
Dim lngImgSize As Long
Dim lngImgOffset As Long

If Len(objMsgFormat.sImageData) > 0 Then    ' String
   varImg = objMsgFormat.byteArrayImage     ' Convert String to Byte
   lngImgSize = LenB(varImg)
   lngImgOffset = 0
   Do While lngImgOffset < lngImgSize
      varChunk = LeftB(RightB(varImg, lngImgSize - lngImgOffset), 100)
      rs!Signature.AppendChunk varChunk   ' This line cause the error
      lngImgOffset = lngImgOffset + 100
   Loop
End If

Can somebody assistance me to sovled this.

Rgds
