I want to create a new object in a layer. The method is simple : layer.addfeature (feature, rowvalues)
Creating and filling feature is OK. Filling rowvalues is also OK. But what is the best method for creating an empty set of rowvalues ? I use the following code (VB6) : dim ds as dataset dim rvs as rowvalues dim l as layer Set l = MapXMap.Layers.Item("mylayer") Set ds = MapXMap.DataSets("mylayer") Set rvs = ds.RowValues(0).Clone() This does not work if you call l.BeginAccess miAccessReadWrite before the line "set rvs = ...", in which case the "set rvs" call raise error 1049. The solution was to call "set rvs" before "l.BeginAccess", but that is probably some kind of voodoo programming since using the program through Citrix and TFE causes the error again... (Well, I know, i'm looking for troubles :-). Even worse, the same error occurs on an other PC on a big file ... but works on mine. This is looking more and more like black magic ! Is there other solutions ? I use also the following sequence elsewhere : Set rvs = New MapXLib.RowValues Set rvst = layer.DataSets.Item("mylayer").RowValues(0) For i = 1 To rvst.Count rvs.Add rvst(i) Next i which give also strange results : the first time, row values are filled with the values of the latest object read in "mylayer", but after that, it's OK and the values are empty or null depending the definition in the table... Any idea is welcome, as any better documentation than the MapX manual...
