Can we have an alternative to EnumCompositeBuffer in LotusScript? (by Johnny Jiang, 10/26/2007 10:24:25 PM) |  |
Hi Normunds,
This is my 2nd question sent to you for help, as I couldn't find out an existing solution at ls2capi.com and even google.
I wonder if there is a way we can simulate EnumCompositeBuffer in Lotus C API in LotusScript to traverse richtext items?
I got the following statement from Lotus C API reference:
...Since each CD record may have a different header and a different length, parsing a CD buffer is fairly complex....
I viewed your ready-to-use samples, it seems that if we know how CD-Records align in a richtext item, it's simpler for us to read them through. But if we are facing a completely strange richtext item and have no idea how it's CD-Records align, we must use some special methods such as EnumCompositeBuffer. I hesitate to try LotusScript version of EnumCompositeBuffer as I saw your comments:
• Function uses callback(s) or is used by a callback; from LotusScript may be used in a limited way or may not be usable all.
• The use is either non-verified or requires special considerations; see comments if available!
Even with the regular ODSReadMemory, I'm even expreriencing diffculty using it.
I was trying to retrieve the $ACTIONS item from Notes forms, and iType is returned as 0 or 1, I doubt if it is correct.
'Get the actionbar field in the note
ret = CNSFItemInfo(m_hMemory, _
ITEMNAME_ACTIONS, _ '$ACTIONS
Len(ITEMNAME_ACTIONS), _
biItemBlockID, _
longValueDataType, _
biValueBlockID, _
longValueLen _
)
If (ret <> C_NOERROR) Then
Error ret, Me.GetErrorMessage(ret)
End If
'Lock the block and get the memory pointer
longPtrMem = COSLockObject(biValueBlockID.pool) + biValueBlockID.block
'Get type, skip it as I don't know what iType means ***
Call CODSReadMemory(longPtrMem, ODS_WORD, iType, 1)
'Read the actionbar information from the memory pointer
Dim structCDActionBar As CDACTIONBAR
Call CODSReadMemory(longPtrMem, _
ODS_CDACTIONBAR, _
structCDActionBar, _
1)
Thanks for your time and appreciate your help.
Kind Regards,
Best regards,
Johnny
