[fdo-users] How to attach/detach a property from a propertyvalues of IInserCmd

[Romica Dascalescu]

So we have:
public class DataValue : LiteralValue
{
  public virtual void SetNull();
}
public class GeometryValue : LiteralValue
{
  public void SetNull();
} 

public class PropertyValue : Disposable
{
    public ValueExpression Value { get; set; }
}
public class Expression : Disposable
{
   public ExpressionItemType ExpressionType { get; }
}

PropertyValue mypVal=...;
ValueExpression vexp = mypVal.Value;
switch (vexp.ExpressionType)
{
    case ExpressionItemType_DataValue:
    { 
       DataValue dv = vexp as DataValue;
       dv.SetNull();
    }
    break;
    case ExpressionItemType_GeometryValue:

    { 
       GeometryValue gv = vexp as GeometryValue;
       gv.SetNull();
    }
    break;
}

Or in case FDO 3.4 do not have ExpressionItemType :

PropertyValue mypVal=...;
ValueExpression vexp = mypVal.Value;

DataValue dv = vexp as DataValue;
if (dv != null){
   dv.SetNull();
}else{
    GeometryValue gv = vexp as GeometryValue;
    if (gv != null)
        gv.SetNull();
}

Hi Romy,

I don't see a SetNull() method in either PropertyValue or PropertyValues. I
am using FDO 3.4 and .NET API.

Thanks,
Ray
