Fail to save attribute value if it is null

ImvecUser1_(Delete)_2148388

We are using LAPI9.0 on VB and we have questions regarding saving attribute values in particular catVersion. Actually I can successfully save the attributes if the value is not null. However if it is an empty value, the attributes cannot be updated. Please advise.Here is the code:For i = 0 to hiddenAttrNo - 1Select Case hiddenAttrType(i)Case 10'10 is for type StringPopupDim inStrValue2 as stringinStrValue2 = ""'if inStrValue is not null, the following codes work fine and be able to save attributes 'however if the inStrValue2 is null, the first and second status return zeros but it shows "101404"'in the final statusstatus = LL_ListSetString(hiddenAttrValues, v, inStrValue2)status = LL_AttrSetValues(hiddenSession, hiddenCatVersion, hiddenAttrName(i), LL_ATTR_DATAVALUES, hiddenAttrPath, hiddenAttrValues)status = LL_SetObjectAttributesEx(hiddenSession, hiddenObjectID, hiddenCatVersion)msgbox statusCase -1:::End SelectNext i This is pretty urgent. Please advise. Thanks in advance.Jovi

To determine why a lapi function returned an error and to provide more details you might want to use code similar to that shown in the following Reply from another LAPI Discussion thread,https://knowledge.opentext.com/knowledge/livelink.exe?func=ll&objId=2510790&objAction=viewIn addition to what that code segment does, I would output the "status" and "message" variable's values as well.
